    Carrier-like profile
    The invention relates to a profile, comprising a first layer and a second layer, which form a hollow structure by at least one web, preferably by a plurality
    Webs, are connected.
    Furthermore, the invention relates to a construction element formed from a plurality of profiles.
    Furthermore, the invention relates to a use of such a profile or such a construction element.
    Support-like profiles consisting of two layers, which are connected to webs and thereby form a hollow structure, are known from the prior art. such
    Profiles are used as building blocks of construction elements, with which the conflicting requirements on the one hand high load capacity, on the other hand at the same time low weight is turned off.
    From EP 1 957726 A1 a support element consisting of two layers, which are connected with webs to form a hollow structure, is known. The webs have along the support member at regular intervals one-sided cuts, creating a lamellar expression is achieved. To improve the stability of adjacent web plates are deformed equal to each other and spaced from each other with the incision side layer connected. To fulfill further heat and sound technology
    Requirements, the cavities may be filled with materials.
    Although, according to the prior art, a good compromise between the
    Carrying capacity and the weight of beam-like profiles is achieved by their
    Void content is increased so far that only a supporting skeleton remains in the form of webs, the strength and in particular the breaking strength and the stiffness of profiles is limited by the fact that in case of load of local inhomogeneities in
    Layer material or web material stress increases occur
    Starting points for crack formation in the material represent. By further spreading such cracks in the material structure in the sustained load case, the strength and rigidity of the overall structure of the profile is reduced. In particular, in the case of
    Wood materials the cracking of wood defects by inhomogeneous swelling and
    Shrinkage of the wood, especially in moisture-changing environment, further reinforced and thereby further reduces the strength of the profile.
    This is where the invention starts. The object of the invention is to provide a carrier-shaped profile of the type mentioned, in which the load-bearing properties, in the
    Particular strength and / or rigidity of the profile are increased.
    Another object is to provide a structural element of the type mentioned, in which the load-bearing properties, in particular strength and / or rigidity of the profile, are increased.
    Further, it is an object to provide a use of such a profile or design element.
    The object is achieved in that in a profile of the type mentioned, the first layer and / or the second layer is at least partially formed with a plurality, preferably glued together veneer layers.
    An advantage achieved by the invention is the fact that in addition to the known
    Optimization of the load-to-weight ratio by forming a hollow structure, the carrying capacity and in particular the strength and / or rigidity of the profile is further increased in that a homogenization of the sheet material is achieved by at least partial formation with multiple veneer layers. As a result, on the one hand cracking is reduced, as greater inhomogeneities in the
    Material structure are inhibited within a veneer layer sequence, and on the other hand, a crack propagation inhibited because a veneer layer assembly, consisting of a sequence of several interconnected veneer layers is an obstacle to an already formed crack.
    Another advantage of at least partially formed with multiple veneer layers
    Location is in which acting in the case of the load on the outer surface of a layer
    To divert forces within the situation. The individual veneer layers can also be formed with different thicknesses or the veneer layer thicknesses can vary within and / or between the layers. The veneer layers can, depending on
    Requirement and expected later load, be arranged at different angles to a layer outer surface. Particularly preferred is a
    Veneer sheet orientation parallel or vertical to the sheet outer surface. A layer can be formed largely of veneer layers; However, the veneer layers can also, depending on the requirement, only be introduced in a targeted manner to specific, in particular loaded, locations of a layer. Further, several non-contiguous sequences of veneer layers within a layer can not be arranged parallel to one another. This makes it possible to influence the rigidity, in particular the bending stiffness of the layers and thus a further tuning of the
    Profile structure on the load case.
    It is additionally advantageous to see that the shape design of a layer is simplified by at least partially forming a layer with veneer layers, since curvatures, in particular those with a small radius of curvature, can easily be formed by veneer laminations. This makes it possible to match the profile shape early on to the intended purpose.
    A veneer layer is preferably formed with a thickness of less than 8 mm, preferably with a thickness between 0.2 mm and 6 mm, particularly preferably with one
    Thickness between 0.5 mm and 3 mm, in particular about 1 mm. A connection of
    Veneer layers with each other preferably by means of adhesive or a
    Adhesive layer. It is useful to glue, preferably synthetic resin or
    Polyurethane glue (PU glue) used. Depending on the later application but can also plaster or cement as a material for connecting layers between
    Veneer layers be expedient.
    Depending on the desired material properties, the veneer layers can be connected to one another with respect to their fiber directions parallel to one another or at an angle to one another. Particularly preferred is an alternating crosswise
    Alignment of the fiber courses, in which the fiber path of a veneer plate to the next an angle of about 90 ° and this includes
    Arrangement system along the next veneer layers continues analogously. It is expedient if the two outer veneer layers of a sequence of interconnected veneer layers aligned parallel to each other
    Have fiber gradients to avoid warping.
    On the one hand, this makes it possible to restrict the swelling and shrinkage behavior of the wood and, on the other hand, to influence a direction-dependent breaking strength.
    In a particularly preferred variant, the first layer and / or second layer is completely formed with a plurality of veneer layers, preferably glued together. When a layer is formed entirely of veneer layers, the material properties within the entire layer are homogenized and larger wood defects in the material avoided and the effects of remaining inhomogeneities only inhibited effective. Depending on the angle formed by the veneer layer surfaces with the layer outer surface, the material properties of the layer, such as strength, in particular breaking strength and rigidity, can be determined and thus specifically influenced on the overall load bearing behavior of the profile. It is particularly expedient here a veneer layer surface alignment parallel or perpendicular to the outer layer surface.
    In a preferred variant, the first layer and / or second layer with a, preferably glued together juxtaposition of solid elements and
    Veneer layers formed. This represents a compromise between a variant in which a layer of solid material such as solid wood exists, and a variant in which a layer is formed entirely of veneer layers. Both the individual
    Solid elements as well as veneer plywood can be made of different
    Wood species, such as beech, birch or larch, exist and thus combine the various known to the expert properties of the wood species. Veneer layers separated from each other by solid elements can not be aligned parallel to each other, i. have different angles between veneer layer surfaces and outer layer surface. Particularly preferred is an alignment of the veneer layer surfaces parallel or perpendicular to
    Location exterior surface. It can be advantageous if one or more
    Solid elements are formed with solid wood and / or concrete and / or metal and are thus matched to the intended use of the profile. Advantageously, one of the layers may be formed entirely of solid material.
    It is expedient if at least one web projects at at least one end into a groove or fold of one of the layers and is connected there to the layer. By connecting the layers by means of webs, by grooves or folds are introduced into the layers, the webs protrude into these grooves or folds and are connected there to the layers, a continuous component in the form of a profile is created. Such a connection is possible both only for individual webs and only on one side of a web, but particularly preferably on a plurality of webs and on both layers. The webs thus joined to the layers are preferably adhesively bonded to the layers within the grooves or folds, thereby providing a durable bond.
    It may be advantageous to form one or more webs with solid wood and / or concrete and / or metal, which can be influenced in particular on the rigidity and breaking strength of the profile.
    In a preferred variant, at least one web with at least one end, preferably both ends, extends as far as an outer surface of the first layer and / or second layer and terminates flush with the outer surface of the layer. As a result, such a bridge executed over a large area on the side surfaces of its end with the position connectable and a particularly stable connection produced. The side surfaces of the end of the web are preferably by means of adhesive or an adhesive layer with the adjacent
    Connected location element. By a web extends to the outer surface of the situation with which the web is so connected, the web is thus an integral part of this situation and allows reliable dissipation of the forces occurring in the
    Loading case. In an expedient variant, particularly stressed webs are connected in this way to the layers, in particular all the webs, whereby the layers and webs are combined to form a stable component.
    It is particularly preferred that at least one web is formed of a plurality of veneer layers, preferably glued together. As a result, similar to the advantages resulting from an at least partial formation of the layers of veneer layers, a homogenization of the web material is achieved, whereby strength, in particular
    Breaking strength and rigidity of the webs are improved and thus in the case of load, an effective dissipation of the forces is achieved. Furthermore, the formation of the webs from a plurality of joined veneer layers enables a simple design of the webs, since, for example, shapes with curvatures can be easily implemented by veneer layers. The veneer layers can vary depending on
    Requirement have a certain angle to the outer layers surfaces; Particularly suitable is an orientation of the veneer layer surfaces parallel or perpendicular to the outer layers surfaces. A web may be formed of veneer layers of different thicknesses and / or the veneer layer thickness may be between the webs or between
    Bars and layers vary. The veneer layers of the webs are preferably by means of
    Adhesive connected. Appropriately, this glue, preferably resin glue or PU glue is used. Depending on the later application, however, gypsum or cement or concrete can be useful as material for the bonding layers between veneer layers. The veneer layers can be as required
    Material properties with respect to their fiber directions parallel to each other or at an angle to each other. In this case, an alternately crosswise orientation of the fiber progressions is particularly preferred, in which the fiber path of one veneer plate encloses an angle of approximately 90 ° to the next, and this arrangement system continues analogously along the next following veneer layers. It is expedient if the two outer veneer layers of a sequence of interconnected veneer layers aligned parallel to each other
    Have fiber gradients to avoid warping. A veneer layer is preferably formed with a thickness of less than 8 mm, preferably with a
    Thickness between 0.2 mm and 6 mm, more preferably with a thickness between 0.5 mm and 3 mm, in particular about 1 mm. The webs formed from veneer layers can be formed from a different type of wood than the veneer layers of the layers and also the webs with each other may differ in the wood species of their veneer layers. Thus, the requirements for strength and rigidity of the profile can be further tailored to the application.
    It is also advantageous if at least one web, preferably a plurality of webs, as
    Extension of veneer layer surfaces of the first layer and / or second layer oriented transversely to the inner layer surfaces are formed and constitute an integral part of the veneer layer surfaces of the first layer and / or second layer. By the veneer layers of a web are formed as part of the veneer layers of one or both layers, the individual elements web and layer (s) merge into one unit, whereby a particularly effective dissipation of the forces acting on the load is achieved. At particularly stressed points of the tread structure webs may be connected to the one or more layers; In a preferred variant, all webs are fused with two layers and thus created a particularly compact profile. In a particularly preferred variant, both the two layers, as well as all webs are made
    Veneer layers formed and formed the webs as an extension of the veneer layers of the layers, whereby a particularly resilient profile is formed.
    In a preferred embodiment of the profile, the side surfaces of the profile are formed by webs that are flush with the side surfaces of the layers or attached to the side surfaces of the layers and flush with the outer surfaces of the layers. As a result, an edge-free side surface of the profile is given and due to a seamless juxtaposition and extensive bonding, preferably by
    Gluing, multiple profiles to a construction element possible.
    In an advantageous variant, the profile in the profile cross-section has layers with different lengths, wherein the layers are connected by the webs such that the layers are aligned centered with each other, wherein the side surfaces of the profile are mirror-symmetrical to each other. The centered alignment of the layers with simultaneous mirror symmetry of the profile side surfaces allows profiles next to each other to arrange and connect as a result of a structural element.
    By rotating a profile 180 ° at an axis of rotation normal to the profile cross-sectional area, i. the profile cross-section is rotated so that the upper layer is now down and the lower layer is now up, results in a profile shape that can be completely connected to an originally aligned profile shape. Thus, an arrangement is possible in which alternately connect first layer to second layer and vice versa each other and the side surfaces of the profiles rest on each other and stabilizing each other gapless. When loaded, adjacent profiles act as additional stabilizing elements and absorb part of the acting forces across all profiles.
    In an expedient variant, the ends of the webs are connected in the profile cross-section at regular intervals on the first layer and at regular intervals on the second layer, wherein the distances between the ends of the first layer not with the distances between the ends of the webs on the second Match location, whereby a non-parallel arrangement of the webs is realized. Due to the non-parallel arrangement of the webs, which, however, tie at regular intervals to both the first and the second layer, although the layers have different lengths, a force distribution is ensured on the entire opposite layer.
    It is particularly preferred that at least one reinforcing layer which contains adhesive and reinforcing fibers is added between veneer layers of the layers and / or veneer layers of the webs. By joining together two veneer layers by means of a layer comprising adhesive and reinforcing fibers, the strength, in particular breaking strength, is further enhanced. Such a reinforcing layer can be used at particularly stressed points between two
    Veneer layers a layer and / or a web introduced, but also the
    Replace glue joint between a veneer layer and a solid element. In a particularly resistant embodiment, reinforcing layers are introduced between all veneer layers.
    Depending on the type and properties of the reinforcing fibers used, the load-bearing properties, especially strength and stability, of the profile can be further improved and adapted to the later loading case.
    It is useful if the reinforcing layer has a thickness which is smaller than the thickness of a veneer layer. Preferably, the reinforcing layer is formed with a thickness smaller than 3 mm, more preferably with a thickness smaller than 1 mm, in particular with a thickness between 0.1 mm and 0.5 mm. In an advantageous variant, the thickness of a reinforcing layer matches the thickness of an adhesive bond without reinforcing fibers, whereby the structural structure of the profile is not disturbed by introducing one or more reinforcing layers.
    A reinforcing layer has a reinforcing fiber content of 20% by volume to 80% by volume, preferably about 40% by volume to 60% by volume, particularly preferably about 50% by volume. This makes it possible, on the one hand, a desired contribution to the
    To adjust the strength properties of the introduced fibers, but at the same time to ensure a sufficiently strong adhesive bond between the veneer layers, between which the reinforcing layer was introduced. As an adhesive in the reinforcing layer, it is expedient to use glue, preferably synthetic resin glue or PU glue. Depending on the later application, however, gypsum or cement may also be advantageous as a bonding layer between veneer layers.
    It is advantageous if the reinforcing fibers in the reinforcing layer are completely enclosed by adhesive. This ensures that a pronounced
    Adhesive bond between the veneer layers, between which the
    Reinforcing layer was introduced, is present. The effect of
    Reinforcing fibers in the introduced between two veneer layers
    Reinforcing layer can be further influenced by a defined orientation of the reinforcing fibers. While a disorderly orientation of the
    Reinforcing fibers have an isotropic effect in the plane of the introduced
    Reinforcing layer entails, an orderly orientation of the fibers to each other can define a preferred direction of the effect of the reinforcing fibers.
    By a parallel orientation of the reinforcing fibers to each other, their effect can be determined depending on the direction and thus adjusted to the load case. The reinforcing fibers can only within a respective
    Reinforcing layer have a defined orientation to each other; However, a coordination of the orientation of the reinforcing fibers can also take place between several or all reinforcing layers of the profile.
    In a preferred variant, the reinforcing fibers are aligned continuous fibers, whereby a pronounced effect of the reinforcing fibers is determined depending on the direction. In further advantageous embodiments, the reinforcing fibers may be in the form of a braid, fabric, knitted or nonwoven fabric. Thereby, an effect of the reinforcing fiber in several directions can be turned off and, moreover, the introduction of the reinforcing fibers into the reinforcing layer can be accomplished more efficiently and easily.
    The reinforcing fibers may consist of vegetable fibers, animal fibers, mineral fibers, synthetic fibers or metallic fibers, in particular glass fibers, carbon fibers or aramid fibers. It may also be advantageous to incorporate several different types of fibers in one reinforcing layer or to use different types of fibers in different reinforcing layers so as to tune to a specific later loading case.
    In an advantageous embodiment is in the veneer layers of the layers or
    Veneer layers of the webs at least one veneer layer with respect to their
    Wood fiber alignment is not aligned parallel to the wood fiber alignment of the subsequent layer. If the wood fiber orientation of interconnected layers is not parallel, the swelling and shrinkage behavior of the wood is restricted. Furthermore, the directional properties of the wood can also be made more isotropic. If the wood fiber orientation of two or more consecutive veneer layers becomes perpendicular to each of the following
    Oriented veneer layer, can be comparable in these directions accordingly
    Strength and stiffness properties can be adjusted. A more even
    Distribution of the properties is achieved in such a way that a plurality of successive veneer layers an irregular orientation with respect to
    Have wood fiber alignments, or in that one or more
    Veneer layers are formed of a material with irregular fiber distribution, such as chipboard or fiberboard.
    It may also be advantageous, between veneer layers, a layer of concrete or
    Metal bring in order to achieve an additional reinforcement of the layer structure.
    In a further advantageous embodiment, the cavities defined by layers and webs are filled with a material or insulating material. Depending on
    Purpose, such as increasing the carrying capacity, thermal insulation, sound insulation, etc., the cavities may be filled with different materials, such as PU
    Foam, sand, wool material, fiber material etc.
    Another object of the invention is achieved with a construction element of the type mentioned in that profiles according to the invention are arranged side by side and connected to each other, preferably glued together. By connecting several profiles together, a large-scale construction element is created according to the properties of the individual elements of which it consists. The profiles are preferably connected by means of adhesive or an adhesive layer. Appropriately, this glue, preferably resin glue or PU glue used. Depending on the later application but can also plaster or
    Cement be useful as a bonding layer between profiles.
    A use of a profile according to the invention or an inventive
    Construction element is advantageously carried out as a component, which in particular has increased load capacity properties, in particular increased strength and / or stiffness properties.
    Further features, advantages and effects will become apparent from the embodiments illustrated below. In the drawings, to which reference is made, show:
    Fig. 1 shows an inventive profile;
    Fig. 2 shows three variants of a profile according to the invention;
    3 shows an inventive profile with alternating mirror-symmetrical webs.
    4 shows a further variant of a profile according to the invention with solid elements;
    5 shows an inventive profile with a more complex configuration of webs.
    Fig. 6 shows a sequence of veneer layers glued together with a
    Reinforcing layer.
    Fig. 1 shows an inventive profile 1, comprising a first layer 2 and a second layer 3, which are connected to form hollow chambers by a plurality of webs 4 with each other. Both the two layers 2, 3, as well as the webs 4 are formed with interconnected veneer layers 5, wherein the webs 4 are formed as an extension of transverse to inner layer surfaces 8 aligned veneer layers 5 of the first layer 2 and second layer 3. This is on the one hand a homogenization of
    Material properties achieved, eliminating localized material defects and consequential
    Voltage overshoots are avoided, and on the other hand achieved by the formation of the webs 4 as an integral part of the veneer layers 5 of the layers 2, 3, a stable structure and effective dissipation of the forces acting under load. Side surfaces 10 of the profile 1 are formed by webs 4, which are attached to side surfaces 9 of the layers 2, 3 and flush with outer surfaces 7 of the layers 2, 3.
    This edge-free side surfaces 10 of the profile 1 are given and possible as a result of a gapless juxtaposition and effective joining several profiles 1 to a structural element. The side surfaces 10 are mirror-symmetrical to each other. A juxtaposition to a structural element takes place by alternating a profile which is normal to the axis of rotation by 180 ° with a rotation axis
    Profile cross-sectional area is rotated, i. the profile cross-section is rotated so that the first layer 2 now below and the second layer 3 is now above, and a profile 1 with original orientation arranged side by side and preferably connected by adhesive. The webs 4 are also connected at regular intervals to the first layer 2 and at regular intervals on the second layer 3, wherein these distances do not coincide with each other, whereby a non-parallel arrangement of the webs 4 is realized. This allows a power transmission to the entire opposite layer 2, 3rd
    FIG. 2 shows three variants of a profile 1 according to the invention. All three
    Variants have the same basic shape with different length layers 2, 3 and mirror-symmetrical side surfaces. A profile 1 of FIG. 2 a) corresponds to the
    Profile of FIG. 1. Both first layer 2 and second layer 3 and webs 4 are formed with veneer layers 5. Fig. 2b) shows a profile whose first layer 2 with a
    Stringing together of solid elements 6, such as solid wood, and
    Veneer layers 5 is formed. The second layer 3 is completely formed with veneer layers 5. The two layers 2, 3 are connected to webs 4 which are formed from veneer layers 5 and constitute an extension of veneer layers 5 of the second layer 3 oriented transversely to the inner layer surfaces 8. The webs 4 extend with their ends to the outer surface 7 of the first layer 2 and terminate flush with the outer surface 7 of the first layer 2 from. As a result, the webs 4 can be extensively connected to the solid elements 6 at the ends facing the first layer 2, preferably glued.
    Fig. 2 c) shows a profile whose first layer 2 and second layer 3 with a
    Stringing together of solid elements 6, such as solid wood, and
    Veneer layers 5 are formed. The webs 4 are formed of veneer layers 5 and provide extensions of transversely to the inner layer surfaces 8 aligned
    Veneer layers 5 of the two layers 2, 3dar. The webs 4 extend with their ends to
    Outer surfaces 7 of the two layers 2, 3und flush with the outer surfaces 7 of the two layers 2, 3 from. The individual solid elements 6 can consist of different types of wood, whereby the different properties of the wood species within a layer 2, 3 are combined. The formation of the webs 4 with veneer layers 5 in addition to the homogenization of the wood properties within a sequence of veneer layers 5 in addition a simple shaping, whereby the formation of bends can be easily accomplished. Also in this variant webs 4 are connected at regular intervals to the first layer 2 and at regular intervals on the second layer 3, wherein these distances do not coincide with each other, so as to effect a force transmission to an entire opposing plate.
    FIG. 3 shows a profile according to the invention in which first layer 2, second layer 3 and webs 4 are formed with veneer layers 5. The webs 4 are also formed as an extension of veneer layers 5 of the two layers 2, 3, whereby a particularly stable structure is created. The webs 4 are formed such that directly adjacent webs 4 are mirror-symmetrical to each other. Characterized a regular distribution of the cavities formed between the layers 2, 3 and webs 4 is created, which can be better matched to sound requirements, especially when using filler in the cavities.
    Fig. 4 illustrates an inventive profile 1, in which the first layer 2 of a
    Arrangement of solid elements 6 and veneer layers 5 and the second layer 3 is completely formed with veneer layers 5. The webs 4 are formed as an extension of veneer layers 5 of the second layer 3 and extend with their ends to the outer surface 7 of the first layer 2. Again, as shown in FIG. 3, adjacent webs 4 are mirror-symmetrical, but have the difference, that at the first layer 2, the ends of the webs 4 of two adjacent webs 4 are connected directly to each other. Thus, as shown in FIG. 4 are the
    Solid elements 6 are each inserted between two narrowing in their shape webs 4, whereby an additional structural stabilization of the solid elements 6 takes place through the webs 4.
    FIG. 5 shows a profile 1 according to the invention, which is completely formed with veneer layers 5. The profile 1 is characterized by a more complex configuration of webs 4. The webs 4 have a wavy shape, wherein adjacent webs 4 are each formed mirror-symmetrically to each other. The webs 4 are arranged spaced as closely as possible, whereby a vielzählige hollow chamber structure is formed.
    FIG. 6 shows a section VI from FIG. 1 and shows a representation of a sequence of veneer layers 5 glued together. Two veneer layers 5 are connected to one another by means of a bonding layer 12, preferably an adhesive layer. A
    Connecting layer 12 is characterized by a reinforcing layer 11, the adhesive and
    Contains reinforcing fibers replaced. Such a reinforcing layer 11 can be introduced in isolated places at particularly stressed points between two veneer layers 5, or also between a veneer layer 5 and a solid element 6. To maximize the load-bearing properties, all the veneer layers 5 can also be connected by reinforcing layers 11.
