    专利说明:

    The invention relates to a wood / concrete composite component for large spans of over 8 meters according to the preamble of claim 1.
    It is already known to manufacture the ceilings of a building in a wood / concrete composite construction. A wooden beam ceiling or a cross laminated timber ceiling is connected to an overhead concrete slab made of in-situ concrete in such a way that the concrete slab takes over the compressive force and the wooden substructure takes over the tensile force. These layers are sheared together using mouths, screws and special shear connectors.
    The advantages of this wood / concrete composite construction are the higher load capacity compared to a wooden ceiling, - in addition, this wood / concrete composite construction is characterized by physical advantages in fire and noise protection and a very high horizontal rigidity of the Cover for bracing the building.
    In contrast, the disadvantages of this previously known construction are not insignificant. For the application of the concrete, the ceiling has to be poured over all floors like a usual filigree ceiling in a solid construction and harden for several days. In addition, the application of the concrete layer made of in-situ concrete brings a lot of water into this ceiling structure, which contradicts the dry wooden construction. The sealing must therefore be carried out very carefully and is therefore complex. The reinforcement for the concrete slab must be stored and processed in the storeys, which further restricts the available space. Due to the usual massive design of the composite component, its cross-section cannot be used for the building services required today, which is why an additional suspended ceiling is necessary.
    One has therefore already created prefabricated composite components, which are designed, for example, as composite beams (see. DE-A-804036). The previously known composite beam has a wooden upper and lower chord which are connected to one another by a concrete bridge. In order to prevent mutual displacements of the straps and the concrete web, the wooden straps are provided on their sides facing the concrete web with mouths or similar recesses into which the concrete of the web engages. The shear forces are essentially absorbed by the engagement of the concrete web in the recesses of the wooden webs.
    The fundamental disadvantage of these previously known wood / concrete composite components is always the limited span of these composite components, since, as in solid construction, spans over 8 meters are not possible without bias, otherwise the deflection of the composite components is too large and the construction is uneconomical becomes. In addition, the formwork expenditure is noticeable disadvantageously, since the cross-section cannot be used as a finished raw ceiling.
    With the flexible floor plans required today in multi-storey residential and commercial buildings, however, the most possible joist and column-free execution of the floor slabs and thus spans of over 8 meters is crucial for an economical solution.
    There is therefore the particular task of creating a wood / concrete composite component of the type mentioned, with which the construction of a structure can be simplified and accelerated and with which, for example, a resilient floor ceiling can be carried out with spans greater than 8 meters can.
    [0009] The solution to this problem according to the invention consists in the features of the applicable patent claim 1.
    The composite component according to the invention has a lower chord made of wood on which protrude in the longitudinal direction of the lower chord wooden webs which are spaced apart such that the lower chord and the spaced wooden webs have a U-shaped cross-sectional profile. If wood is used here, for example in connection with the lower chord and / or the wooden webs, this term also includes suitable wood-based materials and in particular glued wood, such as glued laminated timber (BSH), laminated veneer lumber (LVL or FSH) or cross laminated timber (BBH) ). An upper belt rests on the wooden webs of this composite component. The top chord is also made of wood, whereby the term wood also means suitable wood-based materials and in particular glued wood, such as cross-laminated timber (BBH), glued laminated timber (BSH), or laminated veneer timber (LVL or VSH). The upper chord, made for example from cross laminated timber (BBH), is placed on the webs connected to the lower chord and can be glued and / or screwed to the wooden webs. The interior of the wood / concrete composite component according to the invention, formed by the U-shaped cross-sectional profile, thus forms a mold cavity into which the concrete required for the concrete walkway can be introduced in the factory or, alternatively, on the construction site, without the need for a complex seal against the wooden components or a sprouting would be necessary during assembly. The usual reinforced concrete reinforcement for the concrete footbridge can already be inserted into this interior space before the concrete footbridge is concreted in the interior of the wood / concrete composite component according to the invention at a given time, possibly also after completion of the building. This means that there is no need to wait for the concrete to harden, which would otherwise hinder construction progress. Concreting the concrete walkway in the U-shaped cross-sectional profile of the composite component, which is designed as an interior, does not require a specialist company, but can be carried out by each company itself after instruction. No special work is required for the production of the composite components according to the invention; rather, these composite components can also be manufactured by a timber construction company itself. With the help of the composite component according to the invention, load-bearing capacities are now also possible in timber construction which are otherwise achievable in solid construction. Since the wood / concrete composite component according to the invention has the concrete walkway as a load-bearing element in its interior, floor slabs with spans over 8 meters, for example 12 meters, are possible, as were previously only possible with the help of prestressed concrete boards. Fire protection REI 90 without fire protection cladding is also possible and the technical building equipment can be planned independently of the supporting structure. Although the wood / concrete composite component according to the invention enables significantly larger spans than was previously possible with the constructions available in wood construction, and although the wood-concrete composite component according to the invention is characterized by a high load-bearing capacity, which corresponds to the load-bearing capacity of solid ceilings is comparable, a floor slab manufactured with the aid of wood-concrete composite components according to the invention has a quarter of the weight compared to a solid slab. The high proportion of wood in the wood / concrete composite component according to the invention also results in a CO2 reduction and improved sustainability. With the help of the wood / concrete composite component according to the invention, the construction of a structure is simplified and accelerated, so that within a short time For example, a resilient floor ceiling, also with spans greater than 8 meters, can be implemented.
    The high resilience of the wood / concrete composite component according to the invention is additionally favored if at least one lower voltage is provided, which is held on both sides with their end regions on an upper chord made of wood and in the section of the at least one lower chord on the lower chord between the end regions is. In order to limit the deflection, at least one lower tension can be provided in the wood / concrete composite component according to the invention, which is held on both sides with its end regions on the upper chord and in the section of the at least one lower tension on the lower chord between the end regions. Since the prestressing force generated by the at least one sub-tension is introduced into the upper flange of the wood / concrete composite component according to the invention, the problem of the marginal moments occurring in the known prestressed constructions and in particular in prestressed concrete hollow planks is eliminated. A defined pre-tensioning is applied by the at least one undervoltage, whereby the composite cross-section of the wood / concrete composite component according to the calculations is “pushed up” by the deflection forces and therefore increased. A precise adjustment of the composite components used for a floor slab can be achieved by a subsequent further prestressing on the finished concreted wood / concrete composite component. Such an under-tensioning can also be dispensed with if the wood / concrete composite component according to the invention is to be used with a span of less than 8 meters or if, even with larger spans, a particularly high load-bearing capacity is not required.
    In order to be able to easily fill the concrete required for concreting the concrete footbridge into the interior space formed by the U-shaped cross-sectional profile, it is advantageous if the U-shaped cross-sectional profile formed from the lower flange and the wooden webs is open at the top.
    So that a space-saving use of the wood / concrete composite components according to the invention is additionally promoted, it is advantageous if reinforcement for the concrete pier is provided in the interior of the composite component limited by the U-shaped cross-sectional profile. The reinforcement therefore does not have to be stored in the storeys and processed on the construction site itself.
    In order to pass on the thrust and pressure forces acting on the wood / concrete composite component, it is advantageous if the concrete web forms a shear assembly with the lower chord and / or the upper chord.In order to make the U-shaped cross-sectional profile formed from the lower chord and the wooden webs open towards the top despite the upper chord placed on the wooden webs and to be able to pour the concrete required to complete the concrete web into the interior of the concrete composite component on the construction site, if necessary advantageous if at least one filling opening for filling in the concrete forming the concrete web is provided in the upper flange.
    A preferred embodiment according to the invention provides that the shear connection between the upper flange and the concrete web is formed or supported by the concrete web protruding into the at least one filling opening.
    In addition or instead, it can be advantageous that the thrust connection between the lower chord and / or upper chord is formed or supported by means of mouths in the lower chord or upper chord. The mouths in the lower chord and in the upper chord are provided at roughly the same points of the lower chord and upper chord and establish the shear connection between the concrete web and the upper or lower wooden chord.
    In order to be able to deliver the components of the wood / concrete composite component according to the invention with the least possible effort to the construction site, and to additionally reduce the manufacturing costs for completing the wood / concrete composite component according to the invention, it is advantageous if the concrete walkway is made In-situ concrete and / or made of self-compacting concrete.
    The completion of the wood / concrete composite component according to the invention at the construction site itself is favored if the interior is designed as a mold for the concrete footbridge and if the interior space bounded by the lower chord and the wooden webs is decided at its end oriented transversely to the longitudinal extension of the composite component . Thus, the in-situ concrete must be poured into the interior space provided with the concrete reinforcement on the construction site, possibly only after completion of the building, in order to form the concrete web provided in the interior space after the concrete has hardened.
    A floor slab created with the help of the wood / concrete composite components according to the invention can be produced in a simple manner and integrated into the structure when the top chord protrudes over the cross-sectional profile formed by the lower chord and the wooden webs and when the protruding end regions of the upper chord each Form a support for the composite component. Thus, the composite component with the end regions of its upper chord protruding on both sides only has to be placed on a shoulder of the building that defines the floor slab in order to complete the required floor slab by stringing together several such composite components, without the need for complex sealing or spewing.
    A preferred embodiment according to the invention provides that the at least one lower voltage is designed as a steel rod, which is preferably made from a high-strength steel bar.
    A preferred development according to the invention provides that the at least one lower tension is held on the upper chord at at least one of its end regions by means of at least one support bracket, a lug or the like anchor. Through this anchor, designed for example as a steel bearing bracket, the desired prestressing force is stored in the upper flange of the wood / concrete composite component according to the invention, so that the problem of marginal moments occurring in the known prestressed constructions is eliminated. Such an anchor also makes it possible to place the composite component according to the invention by means of the end regions provided on the upper chords and serving as supports. Therefore lintels and joists can be integrated into the ceiling and, in contrast to the usual wood and wood-concrete composite ceilings, can be made flush with the ceiling without any effort.
    [0022] An embodiment is preferred in which the composite component has at least two sub-voltages which are held at at least one of their end regions by means of a common anchor.
    A particularly advantageous further development according to the invention provides that the composite component has at least one installation channel oriented transversely to the longitudinal extension of the composite component and penetrating the wooden webs and the concrete web of the composite component. Several installation ducts are also possible in the composite component according to the invention without static disadvantages. With the help of these installation ducts integrated into the composite component according to the invention, the ceiling space between the upper flange and the lower flange can be fully used for installations of the TGA in the longitudinal and transverse directions. In the case of a floor slab completed with the aid of the composite components according to the invention, a complex, suspended ceiling can thus be dispensed with.
    A particularly advantageous embodiment according to the invention provides that a structural ceiling can be produced by means of a plurality of composite components abutting one another along their length.
    [0025] Further developments according to the invention emerge from the following description of an exemplary embodiment according to the invention in conjunction with the claims and the drawing. The invention is described in more detail below using a preferred exemplary embodiment.
    It shows:<tb> Fig. 1 <SEP> a wood / concrete composite component shown in a perspective side view, whereby a floor ceiling can be produced in a simple manner with the aid of several composite components lying alongside one another,<tb> Fig. 2 <SEP> the composite component from FIG. 1 in a cross section,<tb> Fig. 3 <SEP> the composite component from FIGS. 1 and 2 in a longitudinal section, wherein the composite component in FIG. 3 rests on both sides on a building shoulder or the like and wherein the end regions of an upper chord of the composite component protruding on both sides serve as supports, and<tb> Fig. 4 <SEP> the composite component from FIGS. 1 to 3 in a plan view of the upper chord, the upper chord being shown transparently in the area of an interior formed by the lower chord and the wooden webs connecting the lower chord to the upper chord.
    1 to 4, a wood / concrete composite component 1 is shown in different views. With the help of several such composite components, which are adjacent to one another along the length, the floor slabs in a multi-storey residential building or commercial building can be created quickly and easily. The wood / concrete composite component shown here is characterized by its high load capacity, even with large spans of over 8 meters.
    The composite component 1 has a lower chord 2 made of glued laminated timber. On this lower chord 2, wooden webs 3, 4 protrude in the longitudinal direction of the lower chord 2, which are spaced from one another in such a way that the lower chord 2 and the spaced-apart wooden webs 3, 4 have a U-shaped cross-sectional profile. The interior space formed by the U-shaped cross-sectional profile forms a mold cavity into which the concrete required for a concrete pier 5 can be placed in the factory or alternatively on the construction site without the need for an expensive seal against the wooden construction elements 2, 3 and 4 or a sprouting of the Composite component 1 would be required during assembly. In the interior space formed by the lower chord 2 and the wooden webs 3, 4, two lower tensions 6, 7 are provided, which are held on both sides with their end areas on an upper chord 8 and in the section of the lower chord 6, 7 between the end areas on the lower chord 2 .
    The lower chord 2 forms the U-shaped cross-sectional profile that is open at the top by screwing and / or gluing to the wooden webs 3, 4. A conventional reinforced concrete reinforcement is inserted into the U-shaped cross-sectional profile that forms the interior of the composite component 1. In the U-shaped cross-sectional profile, the two steel rods forming the under-tensions 6, 7 are installed in the form shown so that after completion of the composite component 1, these under-tensions 6, 7 can be prestressed in such a way that a calculated elevation of the composite component 1 occurs. The top chord 8, which is preferably made of cross-laminated timber, is placed on the wooden webs 3, 4. The upper belt 8 is glued and / or screwed to the wooden webs 3, 4. In the upper flange 8 there is at least one filling opening 9 and preferably several filling openings 9 which are used to introduce the concrete required for the concrete web 5. The concrete required for the concrete web 5 is poured into the mold cavity formed by the U-shaped interior space in such a way that the concrete web 5 also engages in the at least one filling opening 9 after hardening. Thus, after the concrete required for the concrete web 5 has hardened, the filling openings 9 partially produce the shear bond between the concrete web 5 and the upper chord 8. In addition, in the upper chord 8 and in the lower chord 2, for example, 4 cm deep and approximately 25 cm long mouths or similar depressions are provided, which are arranged on the upper chord 8 and the lower chord 2 at approximately comparable points. The arrangement of the mouths 10 producing the shear assembly and of the filling openings 9 is preferably provided in accordance with the static load on the composite component 1. A simple transport of the composite component 1 to the construction site and the simple and quick assembly of a floor slab with the aid of the composite components 1 is promoted if the concrete web 5 provided in the composite components 1 is made of in-situ concrete and / or self-compacting concrete. For this purpose, the interior of the composite component 1 is designed as a casting mold or promnest for the concrete web 5. In order to facilitate the sealing of the interior serving as a mold cavity for the concrete web 5, the interior bounded by the lower chord 2 and the wooden webs 3, 4 is designed to be closed at its end faces oriented transversely to the longitudinal extension of the composite component 1.
    1 and 3 it can be seen that the upper chord 8 protrudes beyond the cross-sectional profile formed by the lower chord 2 and the wooden webs 3, 4 and that the protruding end regions of the upper chord 8 each form a support for the composite component 1. For this purpose, the end regions of the upper flange 8, which serve as supports, each rest on a shoulder 12, 13 provided on the walls of the building.
    In FIGS. 1, 2 and 4 it can be seen that the lower tensions 6, 7 are held on the upper chord 8 at their end regions by means of a catch, a support bracket or similar anchor 14. The two lower voltages 6, 7 are each held at their end regions by means of a common armature 14. The undervoltages 6, 7, designed as steel rods and made of high-strength steel bars, are anchored and secured in the anchors 14. The anchors 14 are held in recesses that are open at the edge on the end regions of the upper chord 8, which also serve as supports. The composite component 1 can be concreted in the factory or on the construction site in the installed state without further support and without further sprouting. The top-side filling openings 9 provided in the upper chord 8 are used for this purpose. It is possible to tension the composite cross-section of the composite component 1 again after the concrete required for the concrete web 5 has hardened, in order to obtain a precisely defined additional elevation of the composite component 1. This elevation can be designed in such a way that the deflection caused by the weight of the composite component 1 in the center of the field is eliminated.
    Since the interior, essentially formed by the lower chord 2 and the wooden webs 3, 4, forms the cavity for the concrete web 5, only a small amount of water is produced. Due to its high proportion of wood, the composite component 1 can also be manufactured by a timber construction company itself, whereby no specialist company is required for concreting the concrete bridge 5 in the composite component 1, but can be carried out by each company itself after instruction. Since no complex sealing is required and since the composite component 1 does not need to be sprouted off during assembly and hardening of the concrete web 5, the space required to assemble the composite component 1 at the construction site is low. Since the reinforcement required for the concrete web 5 can already be inserted into the interior of the composite component 1, additional reinforcement on site at the construction site can be avoided. Since the concreting of the concrete pier 5 can also take place after the building has been completed and since there is no waiting for the concrete pier 5 to harden, the construction progress is not hindered.
    Since the prestressing force of the undervoltages 6, 7 is introduced into the upper chord 8 by means of the armature 14, 15, which is designed here as a steel bearing bracket, the marginal moments occurring in the known prestressed constructions are omitted. The composite component 1 can be placed on both sides of the end regions of the upper chord 8 by means of the anchors 14, 15, which are designed here as steel bearing brackets. As a result, lintels and joists can be integrated into the ceilings produced with the help of such composite components 1 and, in contrast to conventional wood and wood-concrete composite ceilings, can be made flush with the ceiling without any effort. In Figure 3 it can be seen that the composite component 1 has at least one and preferably at least two, oriented transversely to the longitudinal extension of the composite component 1 and the wooden webs 3, 4 and the concrete web 5 of the composite component 1 penetrating installation channels 16. The integration of these installation channels 16 in the composite component 1 is possible without static disadvantages. The installation channels 16 already integrated in the composite component 1 according to the invention and the spaces remaining between the wooden webs 3, 4 of adjacent composite components 1 open up the possibility of fully filling these ceiling cavities between the upper flange 8 and lower flange 2 for installations of the building services in the longitudinal and transverse directions of the floor slab to use. This means that there is no need for an expensive, suspended ceiling.
    A preferred use of the composite component 1 shown here provides that a structural ceiling can be produced by means of a plurality of composite components 1 abutting one another along their length. With the help of the composite component 1, floor slabs with spans over 8 meters and, for example, 12 meters, can also be created quickly and easily. The concrete web 5 integrated into the composite component 1 serves as a supporting web. To limit the deflection of the composite component 1, a prestress is achieved with the aid of the undervoltage 6, 7. The prestressing applied by the sub-stresses 6, 7, by which the composite cross-section is pushed up as a result of the deflection forces according to the calculations, can be repeated again after the concrete web 5 has hardened in order to achieve an exact adjustment of all composite components 1 used for the floor slab. Concreting of the concrete web 5 provided in the composite component 1 can take place not only in the factory but also on the construction site without sprouting during assembly. Several installation ducts 16 are planned in the composite component 1, which significantly simplify the integration of the building services into the floor. The composite component 1 shown here allows significantly larger spans of over 8 meters than was previously the case with the constructions previously available in timber construction. A high load-bearing capacity is achieved, the composite component 1 having only about a quarter of the weight of a comparable solid ceiling. Due to the high proportion of wood in its wooden elements 2, 3, 4 and 8, a CO2 reduction and improved sustainability can be achieved. Since only a little water is required and since the composite component 1 can be additionally stiffened by the under-tensioning 6, 7, only the slightest deformations are to be expected. The construction height of the floor ceiling formed from several such composite components 1 can - contrary to known designs - be used both in the longitudinal direction of the composite components 1 as well as transversely thereto, and also subsequently for building services.
    The composite component 1 shown here makes it possible to achieve load-bearing capacities that are comparable to solid construction. Spans are also possible that were previously only possible with prestressed concrete boards. The storey ceiling created with the aid of such composite components 1 is characterized by a high level of fire protection without the need for additional fire protection cladding. The TGA can be planned independently of the structure. Due to the significantly lower load of the floor slab created with the aid of the composite components 1, considerable savings can be achieved in the case of the beams and the foundations in the basement or the underground car parks. Since load-bearing inner walls can be saved due to the large achievable spans, the structure constructed with the aid of the composite components 1 is characterized by maximum flexibility.
