Definitions

  • the invention relates to a wood component for a wood-concrete composite construction, wherein for surface bonding of the wood component with concrete in the composite surface to the concrete at least one engageable with the concrete and / or fillable recess is provided, which for receiving shear forces between concrete and Wooden component has at least one substantially transversely to the composite surface oriented edge.
  • the invention relates to a wood-concrete composite construction of at least one such timber component and a bearing element and a profile insert for a wood-concrete composite construction.
  • Wood-concrete composite structures have long been known from the prior art and consist of wooden elements or wooden components, which are shear-resistant connected to a adjacent to a composite surface of the timber component concrete component. Wood-concrete composite structures are used in the construction industry in particular, where the advantages of the building material wood should be combined with the advantages of the building material concrete. Such a construction is based on the basic idea of assigning the compressive forces to the wood in the composite cross section, above all the tensile forces and the concrete.
  • Wood-concrete composite construction can be used as a supporting and / or raumabumbledes component both in new construction as well as in the upgrading of existing wood or wood material constructions.
  • timber component is to be understood as meaning all load-bearing and / or space-enclosing wooden constructions which can be combined with concrete to form a wood-composite construction. These can be both ceiling and wall-forming constructions.
  • the so-called beam construction consisting of a beam layer and possibly arranged thereon wooden formwork, and the so-called board stack construction of juxtaposed standing, nailed or doweled side boards used.
  • cross-plywood or cross-ply timber constructions are increasingly being used. These are cross-glued layers of boards arranged side by side, similar to the construction of conventional plywood panels. Due to their areal structure, such wooden components are suitable for both ceiling and wall-forming constructions.
  • the recesses preferably so-called cervical, which are filled with concrete or are in engagement with the concrete.
  • the recesses In order to introduce the thrust forces, which run essentially parallel to the composite surface, into the wooden component, the recesses have, as abutments for the concrete, substantially flanks aligned transversely to the composite surface.
  • transverse means not only a flank orientation perpendicular to the composite surface, but also any inclined flank orientation different from 0 ° or 180 °.
  • connection means which are firmly connected on the one hand with the concrete and on the other hand with the wood component.
  • mechanical fasteners such as screws, dowels, nails u.
  • fasteners such as screws, dowels, nails u.
  • For use in the distributed over the wooden component recesses long wood screws or dowels are screwed in, which protrude perpendicular to the composite surface over the wood cross-section and anchor-like with the concrete engaged.
  • composite systems of crossed pairs of screws or dowels inclined at 45 ° to the composite surface are also known.
  • Out DE 298 16 002 U1 is a composite construction in which the simultaneous absorption of shear and shear forces is achieved by a positive connection between concrete and wood.
  • the wood-concrete composite construction in the area of the composite surface reinforced concrete strips, glued profiled slats or milled depressions, which extend transversely to the clamping direction of the composite structure.
  • the strips or recesses have in cross section a conical shape and thus an undercut, which serves to accommodate Querzug practitionern.
  • Object of the present invention is therefore to improve wood components and wood-concrete composite structures of the type mentioned in that a flat, durable and sustainable bond between concrete and wood can be achieved regardless of the specific course of the longitudinal thrust forces. Furthermore, the cost and time compared to the known wood-concrete composite structures be further reduced while achieving a high degree of prefabrication.
  • the wooden component is distinguished by the fact that a deformable bearing element is provided on the at least one edge of the recess oriented essentially transversely to the composite surface.
  • a certain longitudinal displaceability between the concrete and the wooden component can be achieved by means of a deformable bearing element on the flank, ie in that region of the recess in which the pressure forces from the concrete are introduced directly into the timber component an effective redistribution of shear forces within the timber component results.
  • a failure of the connecting means in the region of maximum stress, ie in the region of the recesses can be avoided because the redistribution of the shear forces the load capacity of the wood component is used in otherwise less stressed areas with.
  • the arrangement of the recesses can take place independently of the specific course of the longitudinal thrust forces.
  • the recesses or composite means can be arranged substantially at equal intervals. Since the deformable bearing elements all composite means or recesses experience approximately the same stress, and the computational effort to determine the exact number and distribution of the recesses in a concrete composite construction is significantly reduced. The wood component is therefore universally applicable for various applications and less prone to error in its manufacture. Since, in particular, a differentiated distance arrangement of the composite means over the length of the carrier element is eliminated, a total of a fast and systematic production process can thus be ensured.
  • the bearing element consists of an elastically deformable, material. It is conceivable, for example, an elastomeric plastic, rubber and / or bitumen. By a suitable choice of material, the degree of deformability and thus the degree of redistribution of forces can be specifically influenced. Furthermore, it may be provided that the deformability in the limit state of the load-bearing capacity of the construction passes into a plastic or ductile deformability in order to fully exploit the rearrangement capability.
  • the bearing element may be formed substantially rod, strip, rail-shaped or the like.
  • the bearing element may be formed substantially rod, strip, rail-shaped or the like.
  • the bearing element In order to ensure the scheduled adjustment between concrete and wooden component and thus the redistribution of the longitudinal thrust forces, the bearing element according to a further advantageous embodiment of the invention cavities and / or chambers which allow a deformation of the bearing element with a corresponding force.
  • the bearing element with the edge in which the thrust forces are introduced from the concrete into the timber member, firmly connected.
  • the bearing element is glued to the flank, nailed, stapled and / or screwed.
  • other mounting options are conceivable. Accordingly, the bearing elements on the timber component factory pre-assemble, which can increase the degree of prefabrication of wood-concrete composite construction.
  • the at least one recess is formed as Kerve, in particular as milled into the wood component Kerve.
  • the milling of the Kerve allows a particularly simple and fast production of the wood component.
  • the at least one recess for receiving transverse tensile forces between concrete and wooden component at least one, preferably in cross-section wedge-shaped, undercut.
  • the undercut creates a toothing between the wood component and the concrete engaging with the recess, so that a lifting of the concrete from the timber component is avoided.
  • the arrangement described above can for example be achieved in that the two upper layers of the cross-laminated timber are not formed over the entire surface, but that the individual boards are set to gap, so that between the resulting recesses and undercuts concrete can be introduced. Accordingly, the tensile forces resulting from the composite effect can be removed by the toothing of the concrete with the upper board layer.
  • a deformable bearing element is provided on at least one flank of the two upper board layers, preferably on at least one flank of each board of the two layers, so that tensile stresses between concrete and wood cross-section can be distributed evenly on almost all crossed board layers.
  • at least one flank of each board of the two upper layers has a deformable bearing element, a biaxial load transfer in the wood-concrete composite construction can advantageously be achieved due to the crossed arrangement.
  • At least one recess has a profile insert adapted to its cross section, which preferably lines the recess completely, but at least in the region of the flank, the undercut and / or the bottom.
  • the profile insert adapted to the cross section of the recess can be used to fix the deformable bearing element on the region of the profile insert assigned to the flank. Vorzugsswiese, the profile insert a sufficient rigidity or dimensional stability in order to wear the bearing element can.
  • the profile insert should also be sufficiently flexible or deformable in order to be able to introduce it, if necessary, into undercuts of the recess.
  • the profile insert at least partially covers the composite surface in the edge region of the recess, so that the profile insert is also supported on the composite surface.
  • the profile insert is adapted to the shape, in particular to the cross section of the recess. It is conceivable, for example, that the profile insert is trough-shaped or U-shaped and is inserted from above into the recess or Kerve. Preferably, the profile insert is also adapted to the contour of the example wedge-shaped undercut. The length of the profile insert is also measured advantageously according to the length of the recess or Kerve.
  • the profile insert preferably with bearing element fixed thereto, can already be introduced into the recesses or cages at the factory.
  • the bearing element can be either fixed on the side facing the wood component or on the concrete facing side of the profile insert, in particular glued and / or laminated.
  • the profile insert made of plastic and / or metal.
  • a metal sheet preferably a galvanized sheet steel.
  • these materials can be easily adapted to the shape of the recess.
  • metal sheets advantageously have a sufficient rigidity or dimensional stability for receiving and fixing the bearing element, but are at the same time sufficiently flexible or deformable in order to be able to be introduced into undercut areas, if appropriate.
  • the profile insert is fixed to the wood component, in particular via at least one screw connection.
  • the screw connection if present, preferably takes place in the region of the undercut, so that the undercut is automatically reinforced by the screw connection. Accordingly, it is possible to absorb greater transverse tensile forces via the undercut.
  • screws suffice, for example, short full-thread screws with a length of about 5 cm, which are significantly cheaper than the usual for receiving transverse tensile forces composite screws or dowels with a length of at least 20 cm.
  • a first independent aspect of the invention relates to a bearing element of a wood-concrete composite construction with at least one of the features described above, which is suitable for arrangement on a wooden component and / or a profile insert of the type described above.
  • a second independent aspect of the invention relates to a profile insert for a wood-concrete composite construction having at least one of the advantageous features described above.
  • the profile insert is provided with a bearing element according to the invention.
  • a third independent aspect of the invention relates to a wood-concrete composite construction with at least one concrete part and at least one timber component according to the invention, wherein the concrete component is engaged with at least one recess in the composite surface of the timber component.
  • the recess has at least one flank aligned essentially transversely to the composite surface.
  • at least one deformable bearing element in particular a bearing element of the type described above, is arranged to redistribute the thrust forces within the timber component on the at least one flank.
  • the Fig. 1 and 2 show a first embodiment of a wood-concrete composite structure 100 according to the invention, which consists of a wooden component 1 and a so that over the composite surface 4 area connected concrete component or concrete 30.
  • the timber component 1 has a plurality of recesses 2, in particular cervicals 3, which are filled with concrete 30 or with which the concrete 30 is engaged. In this case, any shear forces between the concrete 30 and the timber component 1 are taken up by the flanks 5 of the recesses 2, which are aligned essentially transversely to the composite surface.
  • a deformable bearing element 10 is provided on each of the flanks 5.
  • This preferably consists of a ductile, elastically deformable material, such as an elastomeric plastic, whereby between concrete 30 and wooden component 1 a certain, on the material properties of the Bearing element 10 scheduled to be adjusted displaceability results.

  • the recesses 2 and 3 cerves each have a wedge-shaped undercut 6 in cross-section. This serves to absorb transverse tensile forces, which result from the composite action between concrete 30 and wooden component 1, so that a lifting of the concrete 30 from the timber component 1 is avoided.
  • the undercuts 6 each show from the two ends of the timber component 1 for reasons of static reasons to its center.

  • This ensures that the timber component 1 is isolated from the adjacent concrete 30 in the recesses 2, in particular in the areas of the highly absorbent forehead wood, so that the wood can not extract moisture from the concrete 30 when filling the cerverts 3.
  • For the hydration of the cement is thus always sufficient moisture available, so that the concrete 30 on the entire cross section can achieve a sufficiently good quality and in particular locally sufficient pressure and strength properties.
  • the profile insert 20 also serves to fasten or for receiving the bearing element 10. This is the first embodiment according to the Fig. 1 and 2 at the the timber component 1 facing side of the profile insert 20, in the region of the edge 5, glued.
  • the profile insert 20 with attached bearing element 10 may be formed in particular as a pre-assembly and accordingly constitutes an independent idea of the invention.
  • this pre-assembly can be inserted in a single operation in the milled canned 3.
  • the insertion into the cervix 3 can be done either at the construction site or already at the factory in the production of the timber component 1, which increases the degree of prefabrication of the composite structure accordingly.

  • rod or strip-shaped bearing elements 10 are conceivable.
  • the deformability of the bearing element 10 can also be realized by means of chambers and cavities within the bearing element 10.
  • the screw 40 is advantageously introduced in the region of the undercut 6 in the timber member 1 and there serves at the same time for fixing the profile insert 20 on the timber member 1 and for receiving the resulting transverse tensile forces.
  • a wooden component 1 without concrete 30 neither screws nor other connecting means emerge from the construction, so that several of these elements can be transported in batches one above the other.
  • such elements can easily be committed to the construction site without the risk that protruding fasteners could break off or be damaged in any other way.
