Definitions

  • the present invention relates to a wood-concrete composite structure comprising a concrete element, e.g. a flat concrete slab and a wooden beam.
  • the present invention therefore has the object to solve the problem of creating wood / concrete composite structures with simpler means and more cost-effective in static and heat and sound immaculate way.
  • the rod bundle can be arranged close to the edge for the lateral engagement of the concrete element in the masonry in the concrete element. Randnah is interpreted in a way that the distance of the rod bundle of the masonry is small against the length and / or width of the concrete slab.
  • the rod bundle can be formed of welded Arm istsstäben that occupy the corners of a rectangle and its center of area in cross-section, wherein the penetration points are formed by interruptions of the centrally extending Arm istsstabes.
  • the concept of interruptions in the centrally extending reinforcing bar is particularly simple with regard to the required welding points for creating the rod bundle executable.
  • the masonry for establishing the engagement of the lateral areas of the concrete element is provided with a groove.
  • this groove can be poured in the preparation of the concrete slab by means of the flowable in-situ concrete.
  • the concrete slab For further connection of the concrete slab with the wooden beam, it may be provided to screw the concrete element additionally by aligned at an angle to the vertical screws with the wooden beam.
  • FIG. 1 shows a schematic representation of a cross section through an inserted into a masonry 2 wood-concrete composite structure 4.
  • the masonry 2 may be a static load-bearing structure of any kind and is not limited in the context of the present invention to a masonry exterior wall.
  • the wood-concrete composite structure 4 comprises a concrete slab 6 with reinforcements 8 and a wooden beam 10.
  • the concrete slab 6 and the wooden beam are screwed on the one hand with screws 12 which extend at an angle of approximately 45 ° to the vertical.
  • the connection is achieved by vertically oriented screws 14 (only one screw 14 is shown in the illustration shown), which rest with their screw heads 16 on a rod bundle 18.
  • the screws 14 are of particular importance for the stability of the wood-concrete composite structure 4.
  • the perpendicular to the drawing representation plane extending rod bundle 18 contributes quite considerably to support the forces acting on the screws 14 and prevents forces a tearing out of the screws 14 from the concrete slab 6.
  • the screws 14 are through breakthrough points 22 (man could also speak of interruption points) in the rod bundle (respectively in parts thereof) screwed into the wooden beam.
  • the flat concrete slab 6 positively and non-positively engages its lateral areas in a recess 20 in the masonry 2 similar to a groove.
  • the concrete slab 6 has been produced by means of in-situ concrete, whereby this lateral recess 20 could be poured positively and non-positively.
  • the new building it is so that no explicit groove is created, but is bricked up to the lower edge of the concrete slab 6 or concreted or prefabricated elements are created and then the wood-concrete composite structure 4 is created. Subsequently, then further bricked or concreted or wall panels can be mounted. Nonetheless, even in new construction, the concrete slab 6 with its lateral areas in the recess 20 in the masonry 2.
  • the recess In the renovation of old buildings, the recess must actually be created in the rule, for example, by lamming in the masonry. The recess is then usually open to the top designed to be able to easily bring in-situ concrete for Auflagerung.
  • FIG. 2 shows very clearly that in the flat concrete slab 6, the rod bundle 18 is substantially parallel to the masonry 2 and is arranged substantially centrally above the wooden beam 10.
  • the rod bundle 18 consists in this Au Originalsbeispiel of five selectively welded together reinforcing bars, which occupy the corners of a rectangle and its center of area in cross section (see. Fig. 4 ).
  • the breakthrough points 22 for screwing in the screws are presently formed by interruptions in the centrally extending reinforcing bar 18z.
  • FIG. 3 shown excerpt from the FIG. 2 In the area of the screw heads 16, this entire arrangement and geometry of the rod bundle 18 again makes it clear.
  • FIG. 1 it allows the inventive design of the wood-concrete composite structure 4, not to introduce the wooden beams 10 into the supporting masonry 2, but to let him only to the masonry 2 protrude. All support forces are carried by the concrete slab 6, which then, together with the wooden beam 10, for example, required for a room floor and / or ceiling structure. In this way it can be avoided that the wooden beam 10 must be integrated into the masonry 2, whereby the associated disadvantages can also be avoided.
  • the present solution is also particularly inexpensive (especially in the renovation of old buildings), because, for example, rotten or for other reasons no longer sufficiently stable beam heads can be easily cut off the masonry and a connection of the concrete slab 6 to the wooden beams 10 in a comparatively simple manner by the screw with the screws 12, 14 and the use of the rod bundle 18 for the shear forces receiving screws 14 can be realized. Nevertheless, the non-load-bearing beam heads can also be left simply because the concrete slab 6 takes over the load in the support area. If then the outer wall is still rehabilitated moisture technology, which is usually required, and the rotting of the beam head comes to a standstill.
  • FIGS. 5 to 9 now show a schematic representation of further design options for the reinforcing element 18.
  • FIG. 5 is a running as a downside U-profile reinforcing element 50 is shown.
  • the reinforcing element 50 extends again substantially parallel to the edge regions of the concrete slab not shown here.
  • At comparatively centrally located holes in the substantially perpendicular screws 14 are arranged.
  • This basic pattern is also illustrative FIG. 6 been maintained, which is designed as an upwardly directed U-profile reinforcing element 60.
  • a cup-shaped Arm istselement 70 is conceivable, as this in FIG. 7 is shown.
  • FIG. 8 shows in a further schematic representation of a rail-like designed reinforcing element 80 and FIG.
