    专利说明:

    The invention relates to a reinforcing element as well as to a double wall equipped with the reinforcing element and to a method for producing a structural part, as specified in claims 1, 14 and 15.
    Generic reinforcement elements usually have a two-dimensional base element and intermediate elements for providing a three-dimensional structure. The intermediate elements are usually formed in the form of a lattice girder, with additional pole elements being connected to the two-dimensional base element so as to be detached therefrom, and with the additional pole elements being connected to longitudinal bars on the side remote from the base element.
    Embodiments known from the general state of the art have the disadvantage that the reinforcing element is time-consuming to produce and that at least one shell of a double wall provided with the reinforcing element is in danger of breaking out.
    The present invention has for its object to provide a reinforcing element, which is stably constructed and its production is well automati¬sierbar, and to specify a method for producing such a component.
    This object of the invention is achieved by the measures according to claims 1, 14 and 15.
    According to the invention, a reinforcing element is formed, which comprises a first and a second reinforcing mat with metallic mat rods which are welded at nodal points at an angle to one another. The reinforcing mats are kept at a normal distance from each other with respect to their first and second mat plane by rod-shaped spacers. The spacers are metallically and non-releasably connected by welds, preferably Widerstandsschwei߬, with individual mat rods of the first and the second Beweh¬rungsmatte, wherein at least individual spacers zumin¬dest the first mat plane of the first reinforcing mat in a direction away from the second reinforcing mat direction around a first projection tower over to the outside.
    An advantage of the embodiment according to the invention is that by welding the two reinforcing mats to one another by means of the spacers, a stable three-dimensional reinforcing element can be formed. This reinforcing element can easily be moved by means of a crane or other lifting means and can therefore be transported in an automated or semi-automated production line and can thus be manufactured at any location in order to minimize the throughput times on a production line. Due to the fact that the spacers project beyond the first mat plane of the first reinforcement mat around a first projection, it can be achieved that the three-dimensional and stable reinforcing element can be placed on a flat surface such that the first reinforcing mat lies at a predefined distance to that of the first Supernatant corresponds, can be arranged away from die¬ser flat surface. Thus, the first reinforcing mat can be inserted at the desired location in a component, without having to provide additional support means. A further advantage of the reinforcing element according to the invention is that it can be produced by using as few individual parts as possible and thus has the lowest possible weight on the one hand and, moreover, is easy and cost-effective to manufacture.
    Furthermore, it may be expedient that the spacers also project beyond the second mat plane of the second reinforcing mat in a direction away from the first reinforcing mat towards a second protrusion. The advantage here is that not only the first reinforcing mat in it can be kept defined distance from a flat support surface, but that at a turning of the reinforcing element and the second Be¬ reinforcement mat can be ge maintained at a defined distance from a flat support surface in order to arm a concrete component well.
    Furthermore, it can be provided that the first and second projections are of the same size and between 5 mm and 100 mm, in particular between 10 mm and 50 mm, preferably between 15 mm and 30 mm. The advantage hereby is that when using the reinforcing element according to the invention for creating a double wall, the two wall shells can be executed symmetrically or the same. In particular, can be achieved by the supernatant in angegebne¬nen area that required by the standard or static Überle¬gungen concrete minimum coverage over the first and / or second reinforcement mat can be achieved.
    In addition, it can be provided that the spacers are aligned normal to Mat¬tenebenen. It is advantageous here that the spacers can be positioned quickly and easily between the reinforcement mats during the production process. In addition, thereby the first Beweh¬rungsmatte and the second reinforcing mat can be well positioned to each other.
    Also advantageous is an embodiment according to which it can be provided that protective caps are arranged in at least one end section of at least individual spacers. The protective caps serve in this case during the production process of a double wall as protection for the surface of a Schaβlungspalette on which the reinforcing element rests. After completion of the double wall, the protective caps serve as corrosion protection for the spacers provided with the protective cap. Without a protective cap, the spacers on the surface would be accessible to oxidation-promoting air.
    According to a development, it is possible that the protective caps are made of a plastic material, in particular formed by an injection molded part, and have a receiving bore whose diameter is equal to or ge¬ slightly smaller dimensioned than the diameter of the spacers in the region of the supernatant. In particular, protective caps made of a plastic material have good corrosion resistance and can be produced quickly and easily in mass production. In particular, injection molding parts are suitable for production in a series production process, wherein the shaping of injection-molded parts can be freely selected. If the receiving bore of the protective caps is selected to be slightly smaller than or equal to the diameter of the spacers, the protective caps can be well fitted onto the spacer, so that they do not fall down undesirably during the production process.
    Furthermore, it may be expedient that the protective caps are tapered and / or rounded in an end section facing away from the receiving bore. The advantage here is that the protective caps thereby have a support surface or support end, which can be attached to a formwork element. Furthermore, can be achieved by the taper that in the finished component, such as a double wall, the visible on the surface support the protective cap is as small as possible or as little as possible from the Schutzkappeand the surface can be seen.
    In addition, it can be provided that at an angle to the Abstandhal¬tern extending tie rods are welded to the mat rods of the first and the second Be¬ungsungsmatte. An advantage of the additional tension rods is that the possible parallel displacement of the first and the second reinforcing mat to one another can be prevented or such a parallel displacement can be opposed by a large resistance force.
    Furthermore, it can be provided that the spacers and / or the tension rods are connected to the latter at a distance from the nodal points of the mat rods. The advantage here is that the spacers and / or the tension rods, in particular at their connection points with the mat rods are easily accessible to be welded, for example by means of a manufacturing robot. Thus, a manufacturing robot for producing the reinforcing element according to the invention can be constructed as simply as possible.
    According to a particular embodiment, it is possible for support rods arranged parallel to the reinforcement mats in the region of the second reinforcing mat to be welded to the spacers and / or to the tension rods and form a support plane for the second reinforcing mat. The advantage here is that a positioning of the second reinforcing mat in the manufacturing process for the production of the reinforcing element can be done quickly and easily. Thus, it can be achieved that the second reinforcing mat is arranged as positionally accurate as possible relative to the first reinforcing mat.
    According to an advantageous development, it can be provided that at least one lifting bracket extending between the first and second reinforcing mat and welded thereto is arranged. An advantage here is that the lifting bracket can be arranged as possible in the center of gravity between the two reinforcing mats in order to facilitate handling of the reinforcing element. Furthermore, the lifting bracket can contribute to an additional Stabilisie¬ rung the reinforcing element. Another advantage of a lifting bar welded to the reinforcing mats is that it is connected to the reinforcing element or the double wall with an increased strength. Thus, the likelihood is reduced that during Verhe¬bevorganges of the reinforcing element, or equipped with the Beweh¬ rungselement double wall, this can solve the lifting bracket and thus represents a potential source of danger for people.
    Furthermore, it may be expedient if the mat rods of the first and of the second reinforcing mat are arranged in the normal direction on the mat planes congruent to one another. The advantage here is that the blank of the two reinforcing mats can be made identical or congruent, whereby the production of the reinforcing mats is well automatable. Another advantage of this embodiment is that especially spacers, which are arranged normally on the individual reinforcing mats, can be well positioned on the reinforcing rods and welded to them.
    Furthermore, it can be provided that the spacers and / or the mat strips are made of a reinforcing steel with rolled-in ribs or other surface contours. The advantage here is that with the use of reinforcing steel for the reinforcing element this can absorb increased tensile forces, since concrete can be well connected to the reinforcing steel.
    According to the invention, a double wall is furthermore provided, comprising a first and a second wall shell made of concrete, in which first and second wall shell a reinforcement element according to the invention is at least partially integrated. The first reinforcing mat of the reinforcing element is integrated into the first wall scarf and the second reinforcing mat is integrated into the second wall shell. It is an advantage of the double wall according to the invention that the built-in reinforcing element according to the invention has two mutually distanced Beweh¬ mats, which are integrated into the two wall shells. The use of reinforcing mats increases the pull-out strength of the reinforcing element out of the wall shell compared to a comparable double wall with lattice girder arrangement. Thus, the security can be increased, since unwanted detachment of the wall shell can be kept behind by the reinforcing element. This is particularly important at the construction site, as concrete parts falling down during lifting would pose a serious safety risk to the workers. By using the reinforcing element according to the invention in a double wall, it is moreover possible to increase the filling speed when concreting the double wall against conventional double walls, since the two wall shells are connected in an improved manner to the stable reinforcing element. In addition, the concrete cover of the wall shell can be reduced by the use of a reinforcing element according to the invention, whereby the complete double wall can be manufactured with reduced weight. This brings savings in the production with it. In addition, a weight-reduced double wall can be transported in a cost-effective and environmentally friendly manner, with the handling of the double wall additionally facilitated in the course of a lifting operation.
    In the method for producing a component, it is provided that this method comprises the following steps: providing a first reinforcing mat with metallic mat rods welded at an angle to one another at intersections; - Positioning rod-shaped spacers relative to the mat rods of the first reinforcing mat; - Welding the spacers with the mat rods of the first reinforcement mat; - Positioning a second reinforcing mat at a normal distance from the first reinforcement mat, wherein the second reinforcing mat is positioned such that the spacers between the first reinforcing mat and the second reinforcing mat extend; - Welding the spacers with the mat rods of the second Beweh¬rungsmatte to provide a three-dimensional reinforcement element.
    An advantage of the method according to the invention for the production of a component, in particular of the reinforcing element according to the invention, is that the rod-shaped spacers can be easily positioned or welded to the first reinforcing mat by a production line, in particular by a robot system. The second reinforcing mat can then also be positioned by the production plant, in particular the robot system, relative to the first reinforcing mat and subsequently welded to the spacers, so that a stable, three-dimensional reinforcing element is produced. Such a reinforcing element is so stable that it can be transported as a whole within a production plant or even to external production facilities in order to be able to be used in prefabricated at any place. In particular, the reinforcement element can be prefabricated in a separate production section and subsequently be used as a whole for use in a production process for the production of a double wall. Furthermore, it can be provided that the individual method steps are carried out in a sequence which is different from this enumeration.
    Furthermore, it may be expedient that the spacers are positioned relative to the mat bars of the first reinforcing mat such that the spacers protrude relative to the mat bars of the first reinforcing mat around a first projection. The fact that the spacers project beyond the mat bars of the first reinforcing mat to the outside by a first protrusion, it can be achieved that the three-dimensional and stable reinforcing element can be placed on a flat surface, so that the first reinforcing mat in ei¬nem a predetermined distance corresponding to the first supernatant , can be arranged away from this flat surface. Thus, it is no longer necessary to prepare the formwork pallet with any bottom rails, lattice girders, spacers, etc., as is the case with conventional double-walled windows.
    Furthermore, it can be provided that the second reinforcing mat is positioned in such a way that the spacers protrude with respect to the mat rods of the second reinforcing mat around a second protrusion. The advantage here is that thereby not only the first reinforcing mat can be kept at a defined distance to a flat support surface, but that at einWenden the reinforcing element and the second reinforcing mat can be kept at a defined distance from a flat support surface in order to arm well a concrete component ,
    In addition, it can be provided that before the positioning of the rod-shaped spacers they are cut to length and provided with protective caps on at least one end section. The advantage here is that the rod-shaped spacers, if they are cut to length only in the manufacturing process, can be delivered as Stan¬genmaterial. Thus, an individually adjustable length of all spacers can be realized. It is also advantageous if the spacers are provided with protective caps already after cutting to length and before installation or welding in the first reinforcing mat, since this working step can be combined well with a cutting process in terms of manufacturing technology.
    According to a further development, it is also possible that tension rods running at an angle to the spacers are welded to the mat rods. The advantage here is that the tension rods can be welded easily and inexpensively to the mat stalls during the production process.
    Furthermore, it may be expedient that before the positioning of the second reinforcement mat, support rods running parallel to the first reinforcing mat are positioned and welded to the spacers and / or the tension rods. The advantage here is that support elements are formed by the support rods, on which the second reinforcement mat can be placed during the manufacturing process. Thus, it is easier for the production system or a production robot to be able to end position the second reinforcement mat and to weld it to the spacers and / or the tension rods. In addition, this results in an excessive sagging of the second reinforcement mat during the positioning process relative to the first reinforcement mat te prevented or largely refrained.
    In addition, it can be provided that, after the provision of a three-dimensional reinforcing element, the following method steps are carried out: provision of a horizontally oriented formwork pallet and optional attachment of delimiting formwork on the formwork pallet; - Positioning of the reinforcement element on the formwork pallet; - Optionally supplement or attach limiting formwork on the Schahtlungspalette; Applying a layer of concrete to the formwork pallet, shaking the formwork pallet or layer of concrete as required, until the first reinforcing mat is completely covered; - Storage of the component until solidification or hardening of the concrete layer to a first wall shell. The advantage here is that for Fierstellung a Doppelwand the formwork pallet can be prepared as much as possible and the reinforcing element can be lifted as a whole in the formwork pallet. Thus, it is no longer necessary to prepare the formwork pallet with any bottom rails, lattice girders, spacers, etc., as is the case in the case of conventional double walls. This can greatly improve the quality of the double-wall manufacturing process. On the one hand, the process speed can be increased because the defense element can be lifted as a whole. On the other hand, the
    Process accuracy or repeatability can be increased because the Beweh-tion element can be executed by its preparation as a dimensionally stable component.
    In an alternative variant, it can be provided that, after the provision of a three-dimensional reinforcement element, the following method steps are carried out: provision of a horizontally oriented formwork pallet and attachment of boundary formwork on the formwork pallet; - orders of a concrete layer on the formwork pallet; Dipping the first reinforcing mat of the reinforcing element into the concrete layer, shaking the formwork pallet and / or the reinforcing element as required, until the first reinforcing mat is completely covered with concrete; - Storage of the component until solidification or hardening of the concrete layer to a first wall shell. The advantage here is that the manufacturing process can be additionally accelerated since the concrete layer can already be applied to the formwork pallet before the reinforcement element is inserted. This manufacturing method or Fierstellverfahren can only be carried out using the inventive reinforcing element.
    Furthermore, it can be provided that, after the first wall panel has been flung, the following method steps are carried out: lifting the reinforcement element together with the first wall shell attached thereto from the shuttering pallet; - Turning the reinforcement element together with the attached first
    Wall shell; - Providing a horizontally oriented shuttering palette and attaching Begrenzungsschalungen on the formwork pallet; - orders of a concrete layer on the formwork pallet; Dipping the second reinforcing mat of the reinforcing element into the concrete layer, shaking the formwork pallet and / or the reinforcing element as required, until the second reinforcing mat is completely covered with concrete; - Storage of the component until solidification or hardening of the concrete layer to a second wall shell. The advantage here is that the reinforcing element is already integrated into the first wall shell and due to the stable construction of the reinforcing element, this component can be well moved or positioned in the production process. In addition, the part-ready component can be dipped by a turning device in the exact position in the concrete layer of the preliminary formwork palette, so that the second wall shell can be produced position exact.
    Finally, it can be provided that the storage of the component is carried out until a solidification or hardening of the concrete layer to a first and / or second wall shell in a curing chamber. The advantage here is that the curing process of the wall shells can be accelerated. Thus, the period can be shortened to a sufficient curing of the wall shells so that they are transportable as soon as possible and the shuttering pallet is free again.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the directly described and illustrated figure and these conditions are to be transferred in a change in position mutatis mutandis to the new situation.
    FIG. 1 shows an example of a reinforcement element 1 according to the invention shown in a perspective view. FIG. 2 and FIG. 3 show the Beweh¬ rungselement 1 in a plan view of II of FIG. 1 and a side view nachIII of FIG. 1, wherein the same reference numerals or Bauteilbezeichnungen used for the same parts as in the respective preceding figures become. To avoid unnecessary repetition, reference is made to the detailed description in the respective figures. To illustrate or to explain the invention, the Beweh¬ rungselement 1 is shown only in an exemplary section, wherein the reinforcing element 1 may have larger dimensions than shown.
    The reinforcing element 1 according to the invention can be used as a reinforcement or Armie¬ rung in reinforced concrete. The reinforcement element 1 comprises a first reinforcing mat 2 and a second reinforcing mat 3, each having a first mat plane 4 and a second mat plane 5. The two mat levels 4, 5 are, as can be better seen in FIG. 3, respectively defined by the outermost points of the reinforcing mats 2, 3. It is advantageous if at ei¬nem reinforcement element 1 at least three spacers 8 vorgesehen.Dadurch the reinforcing element 1 can rest well on the spacers 8.
    The reinforcing mats 2, 3 each have a plurality of mat bars 6, which are arranged at an angle to each other. This results in a grid shape wherein the mat bars 6 are welded together at nodes 7 where they overlap. The mat bars 6 are preferably made of a reinforcing steel. A reinforcing mat 2, 3 is a lattice structure of bars welded together. The distance between the individual bars relative to each other can be regular or even irregular.
    These reinforcing mats 2, 3 can be purchased as standard prefabricated parts and cut accordingly on site. In an alternative variant, it is also possible to cut off the mat rods 6 in the course of the manufacturing process of the reinforcement element 1 on site and to weld them together.
    As further shown in FIG. 1, rod-shaped spacers 8 are provided, which keep the individual reinforcing mats 2, 3 spaced apart from each other at a desired and predefined normal spacing 9. The normal distance 9 is the distance in which the two mat levels 4, 5 of the reinforcing mats 2, 3 are arranged at a distance from one another. The rod-shaped spacers 8, which are made of a metallic material, are connected by a Schwei߬ 10 with the mat rods 6. The welded joint is preferably realized by a resistance welding, in particular by a Wi¬derstandspunktschweißung. The advantage here is that this welding process is easy to automate, and that in this welding process no filler material is needed. However, as an alternative to resistance welding, it is also possible for the spacers 8 to be replaced, for example, by a MAG
    Welding process or be connected by a laser welding together.
    Furthermore, as can be seen particularly well in FIG. 3, it may be provided that the spacers 8 protrude in a direction 11 facing away from the second reinforcing mat 3 about a first projection 12 opposite to the first plane of the mat 4. By this expression can be achieved that the reinforcing element 1 can be ideally used for purposes where it is required that the first reinforcing mat 2 from a support plane on which the reinforcing element 1 rests, are arranged at a distance. This is the case, for example, in the production of double walls 13, precast concrete components or in the case of element cladding and the like. In addition, the reinforcing element 1 according to the invention can also be used ideally in order, for example, to reinforce components in situ concrete.
    Furthermore, it can be provided that the spacers 8 are arranged in a direction away from the first reinforcing mat 2 direction 14 about a second projection 15 with respect to the second mat plane 5 protruding. The advantages of this can be seen analogously to the first projection 12.
    By varying the first supernatant 12 and the second supernatant 15, the desired concrete coverage can be adjusted. In other words, it can be set by how far the first reinforcing mat or the second reinforcing mat is arranged away from a concrete surface. The projections 12, 15 are preferably chosen to be the same size, so that the reinforcement element 1 or a double wall 13 equipped therewith is designed to be symmetrical. In an alternative variant or for special applications, however, it is also possible for the supernatants 12, 15 to be selected to vary in size.
    Furthermore, it can be provided that in addition to the spacers 8 also tensile bars 16 are arranged on the reinforcing element 1, which are arranged at an angle 17 to the spacers 8 or to a normal on the mat levels 4, 5. The tie rods 16 preferably extend between the first mat plane 4 and the second mat plane 5. Furthermore, the tie rods 16 are preferably arranged in pairs V-shaped, whereby the reinforcing element 1 increased rigidity can be imparted. In particular, it can be achieved that a parallel displacement of the two reinforcing mats 2, 3 is opposed to one another by increased resistance or increased strength. The tension rods 16 may preferably have a smaller diameter than the spacers 8. In addition, it may be provided that the tension rods 16 have the same diameter as the mesh rods 6.
    Furthermore, it can be provided that, as can be seen from FIG. 2, the spacers 8 and / or the tension rods 16 are connected to them at a distance 18 from the nodal points 7 of the mat bars 6. It can thereby be achieved that the spacers 8 and / or tension bars 16 are readily accessible at their connection points with the mat bars 6. Automated processing by means of a manufacturing robot or a manufacturing plant can thereby be facilitated.
    Furthermore, it can be provided that in the region of the second reinforcing mat 3Auflagestäbe 19 are formed, which define a support plane 20. These support rods 19 may be particularly advantageous in the position of the reinforcement element 1, since they can be well connected to the spacers 8 and tie rods 16, respectively, and to form the support plane 20 upon which the second reinforcement mat 3 can be applied in the manufacturing process. Thus, it can be achieved that the second reinforcing mat 3 is already approximately in its final position during the manufacturing process.
    How out. It can be provided that the spacers 8 are arranged normally on the first mat plane 4 or on the second mat plane 5 on the reinforcement element 1.
    FIG. 4 shows a further embodiment of the reinforcing element 1, which may be independent of itself, and in which again reference signs or component designations are used for the same parts as in the preceding FIGS. 1 to 3. To avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 3 or reference. In FIG. 4, as in FIG. 3, a view according to III of FIG. 1 was also selected.
    In the embodiment of Fig. 4, the rod-shaped spacers 8 are not normal standing on the mat levels 4, 5, but are arranged at an angle zudiesen. It can thereby be achieved that the spacers 8 can assume the function of the tension rods 16 from FIG. 3 and thus the tension rods 16 are not necessary in this exemplary embodiment.
    As can be seen from FIGS. 1 to 4, provision can be made for protective caps 22 to be arranged on at least one end section 21 of the spacers 8, which protect the spacer 8 against corrosion or serve as a contact element in the manufacturing process.
    5 shows a section of a spacer 8 with a protective cap 22 shown schematically. As shown in FIG. 5, the protective cap 22 has a receiving bore 23 in which the spacer 8 can be received. In the illustration from FIG. 5, the protective cap 22 is not completely plugged onto the spacer 8 in order to better represent the interior of the protective cap 22. Preferably, the protective cap 22 will be plugged onto the spacer 8 until it stops. A diameter 24 of the receiving bore 23 is selected to be the same size or smaller than a diameter 25 of the spacer 8. It can thereby be achieved that the protective cap 22 can be pushed onto the spacer 8 under the action of force and firmly seated thereon taken. Thus, the protective cap 22 can not be accidentally shaken down during the manufacturing process. Furthermore, it can be provided that, as can be seen from FIG. 5, the protective cap 22 is designed to be tapered and / or rounded in an end section 26 facing away from the receiving bore 23. In particular, it can be provided that the protective cap 22 has a cone-like shape in the end section 26. As a result, it can be achieved that the protective cap 22 in the end section 26 is made as slim as possible, so that the protective cap 22 is as far as possible or only little visible on the surface of a double wall 13.
    The protective cap 22 is preferably made of a plastic material. This may include, for example, a thermoplastic resin having high chemical resistance and high aging resistance.
    6 shows a side view or a sectional view of a double wall 13, which is equipped with the reinforcement element 1 according to the invention and already described. As can be seen from FIG. 6, a first wall shell 27 is formed in the region of the first reinforcing mat 2, and a second wall shell 28 is formed in the region of the second reinforcing mat 3. In a double wall 13, an intermediate region 29 is formed between the two wall shells 27, 28, which is filled with concrete after erection of the double wall 13 on site to obtain a solid concrete wall. Ideally, the wall shells 27, 28 have the smallest possible wall thickness 30, 31, so that the double wall 13 is as easy as possible for transport. The limits for the minimum wall thickness 30, 31 of the wall shells 27, 28 arise on the one hand due to the minimum coverage, which must have the wall shells 27, 28. This minimum coverage is, for example, that distance from the outer surface 32 of the first wall shell 27 to the first mat plane 4. The minimum coverage can be set by the positioning of the spacers 8 and is the same size as the first projection 12. The same applies to the second wall shell 28, wherein the minimum overlap is also calculated from the outer surface 33 of the second wall shell 28. The wall thicknesses 30, 31 are further given by a required minimum distance of an inner surface 34 of the first wall shell 27 to the first reinforcement mat 2 or an inner surface 35 of the second wall shell 28 to the second reinforcement mat 3. By constructing the reinforcing element 1 according to the invention can be achieved that the wall thicknesses 30 31 can be as small as possible. Due to the use of two reinforcing mats 2, 3 which are stably bound together by the spacers 8, the risk can be reduced that the reinforcing element 1 breaks out of one of the wall shells 27, 28.
    In FIGS. 7 and 8, the production process for producing a double wall 13 is explained or explained on the basis of the schematic illustrations, identical reference symbols or component designations being used for identical parts as in the respective preceding figures. To avoid unnecessary repetition, reference is made to the detailed description in the respective preceding figures.
    In this document, the semi-finished product of the reinforcing element 1bzw. the double wall 13 is referred to as a component 36.
    To create the reinforcing element 1, the first reinforcing mat 2 is provided in a first method step. The first reinforcing mat 2 can in this case be a purchased part or else it is also possible for the first reinforcing mat 2 to be produced directly on site by welding mat rods 6.
    In addition, the spacers 8 are prepared, which are cut to length and can already be fitted with the protective caps 22. Alternatively, it is possible that the protective caps are attached to the spacers 8 only after completion of the reinforcement element 1.
    After providing the first reinforcing mat 2, the bar-shaped spacers 8 are positioned opposite the mat bars 6 of the first reinforcing mat 2 such that the spacers 8 project from the first protrusion 12 opposite the mat bars 6 of the first reinforcing mat 2. If the spacers 8 are correctly positioned, they can subsequently be welded to the mat rods 6 of the first reinforcing mat 2.
    In order to be able to position the spacers 8 projecting above the mat rods 6 of the mat 2, it can be provided that the mat 2 is placed on pad blocks and thus the free space for the first projection 12 is created. Furthermore, it is also conceivable for the first reinforcing mat 2 to rest on a flat surface in which recesses are introduced, whereby the spacers 8 can be introduced into these recesses and thus can be arranged above the first reinforcing mat 2 in the flanging position process.

    In a variant, it is also conceivable for the first reinforcing mat 2 to be held in position by a gripping system of a robot and for the robots to position and weld the spacers 8 relative to the first reinforcing mat 2 by means of another robot.
    Furthermore, it is also conceivable that in addition to the spacers 8 also tensile bars 16 are positioned on the first reinforcing mat 2 and welded thereto.
    In a subsequent method step, the second reinforcing mat 3 is positioned at the normal distance 9 from the first reinforcing mat 2 and welded to the spacers 8. Again, it is possible that the second Beweh¬ mat 3 is held by means of a robot system or other manufacturing plant in position and then welded.
    Furthermore, it is also conceivable that before positioning the second Beweh¬ mungsmatte 3 parallel to the first reinforcing mat 2, the support rods 19 are positioned parallel to the first reinforcing mat 2 and welded to the spacers 8 and or Zugstäben 16, so that the support plane 20 is formed. The second reinforcing mat 3 can now be laid on this support plane 20, whereby an excessive deformation of the second reinforcing mat 2 is reduced or avoided during the manufacturing process.
    With these method steps, the three-dimensional reinforcement element 1 is now produced, which serves as the basis for the further method steps for producing the double wall 13. The reinforcing element 1 can be transported or positioned well in a production shop or in the production process for producing the double wall 13 by means of a load lifting crane within the production facility, which enables the reinforcing element 1 to be prefabricated independently of the actual production steps for producing the double wall 13. As a result, the production process for producing the double wall 13 can be considerably simplified or rationalized.
    As can be seen from FIG. 7, provision can be made for the welded and thus stable reinforcing element 1 to be positioned on a shuttering pallet 37, the spacers 8 resting in particular on their end section 21 on a surface 38 of the shuttering pallet 37.
    In this case, it is possible for the reinforcing element 1 to be placed on the shuttering pallet 37 first, and then limit shuttering 39 to be positioned on the shuttering pallet 37 in order to allow the concreting operation. Alternatively, it is also conceivable that the boundary shuttering 39 are first positioned on the shuttering pallet 37 and then the reinforcing element 1 as a whole is lifted onto the shuttering pallet 37.
    If the reinforcement element 1 is positioned as shown in FIG. 7, the actual concreting process can be started. Here, a concrete layer 42 is applied to the formwork pallet 37 by means of a concrete supply device 40. It can be provided that the Betonbereitstellungsvor¬richtung 40 is moved back and forth in a horizontal direction of movement 41, so that the concrete layer 42 is evenly distributed on the shuttering pallet 37. In this step, so much concrete is applied to the shuttering pallet 37 until the desired wall thickness 30 of the first wall shell 27 is reached, and thus the first reinforcement mat 2 is completely covered by the concrete layer 42.
    In an alternative variant, it may also be provided that the concrete layer 42 is first applied to the shuttering pallet 37 prepared with boundary formworks 39, and then the reinforcement element 1 is lifted onto the mounting pallet 37 so that the first reinforcing mat 2 enters the passing concrete layer 42 dips.
    In order to sufficiently compact the concrete layer 42, it can be seen that in the manufacturing process the shuttering pallet 37 vibrates or that a vibrating bottle is introduced externally into the concrete layer 42 in order to adequately compact or homogenize the concrete layer 42.
    After this covering of the first reinforcing mat 2 with a concrete layer 42, the concrete layer 42 is brought to harden and thus forms the first wall shell 27. The curing process can take place here at ambient conditions, or it is also possible that the curing process beispiels¬weise in a curing chamber at elevated temperature is carried out. If the first wall shell 27 is sufficiently hardened to be able to move, the semi-finished component 36, in particular the reinforcement element 1 with the first wall shell 27 arranged thereon, is lifted off the formwork pallet 37 by means of a lifting means and turned over.
    After the turning process, a position as shown in Fig. 8 results. As shown in Fig. 8, after the lifting of the member 36, the Schaβlungspalette 37 again covered with a concrete layer 42 to the concrete for the second wall shell 28 ready to deliver. After this filling process, the structural part 36 is immersed in the provided concrete layer 42 and optionally compacted under Rüt¬teln.
    Subsequently, the concrete layer 42 is cured analogously to the production of the first wall shell 27, so that the second wall shell 28 is produced.
    FIG. 9 shows a further embodiment of the reinforcing element 1, which may be independent of itself, and in which again reference signs or component designations are used for the same parts as in the preceding FIGS. 1 to 8. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 8.
    Fig. 9 shows a perspective view of a complex reinforcement element 1, as is required for the double wall 13 of a house. As can be clearly seen from FIG. 9, recesses 43, for example for windows or doors, are provided in the reinforcement element 1.
    Furthermore, as can be seen from FIG. 9, it is conceivable that lifting hooks 44 are arranged in the reinforcement element 1, by means of which the reinforcement element 1 or, as a further consequence, the finished double wall 13 can be positioned or displaced with a lifting means.
    FIG. 10 shows a further embodiment of the double wall 13, which is possibly independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 9. To avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 9. As an alternative to use in a double wall 13, as shown in FIG. 6, according to FIG. 10 it can be provided that the reinforcement element 1 according to the invention is inserted in a solid wall 45. In contrast to the double wall 13, there is no solid wall 45 Zwi¬ area 29, but the reinforcing element 1 is completely encapsulated in concrete already in the precast plant, so that the solid wall 45 is formed, which can be enthralled or transported as a whole.
    The exemplary embodiments show possible embodiments of the Beweh¬rungselementes 1 or a double wall 13 equipped therewith, it being noted at die¬ser point that the invention is not limited to the specifically illustrated Aus¬führungsvarianten same, but rather also diverse combinations of the individual embodiments with each other are possible and this possibility of variation due to the teaching of technical action by objective invention in the skill of those skilled in this technical field.
    Furthermore, individual features or combinations of features from the different embodiments shown and described can also represent solutions that are inventive, inventive or inventive.
    The problem underlying the independent inventive solutions can be taken from the description. All statements on ranges of values in the description of the subject should be understood to include any and all subsections thereof, e.g. the indication 1 to 10 should be understood to mean that all subregions, starting from the lower limit 1 and the upper limit 10, are included, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
