Definitions

  • the present invention relates to an assembly jig for a connection of two at least partially flat juxtaposed wooden elements and an insert element for generating screw channels in a flat concrete element. Further, the present invention relates to a wood / concrete composite element with at least one such insert element and to a wood / concrete composite structure with at least two wood / concrete composite elements and to the corresponding connection methods.
  • the present invention therefore has the object to solve the problem of connecting wood / wood composite elements, wood / concrete composite elements for the creation of wood / concrete composite structures with simpler means and more cost-effective.
  • the static properties of a connection of the wooden beams which can be achieved by screwing the screws through the conduits, can be achieved particularly well if the spatial course of the conduits in a Cartesian coordination system with the directions x, y and z a course of a spatial diagonal ( or with several conduits also several spatial diagonals) corresponds.
  • This is basically to be understood that in a compound with, for example, four screws, the four screw tips and the four screw heads an octagonal, essentially represent cuboid composite.
  • connection it is also expedient with regard to the computability of the connection and the uniform distribution of tensile and compressive moments on the screws, if the spatial course through an angle of 30 to 60 °, preferably in the range of 45 °, to each of the three directions x, y and z is coined.
  • the screws can be screwed with a manageable amount of force and have an X-shaped arrangement to each other.
  • the one or more conduits of the insert elements during the concreting concrete element can not be closed (unintentionally), the base plate opposite the end of the empty tube with a removable lid can be designed lockable.
  • Screwing the screws through the conduits into the wooden beams requires a comparatively high pressure of the screwing tool on the screw head, which may not protrude significantly beyond the thread cross section of the screw.
  • the above object is achieved by a wood / concrete composite element with at least one insert element according to the above type.
  • a suitable number of such integrated insert elements is provided.
  • a wood / concrete composite structure in particular wall and / or ceiling part, having at least two of the above wood / concrete composite elements, wherein adjacent timber support of at least two Wood / concrete composite elements are connected flat by means driven by the screw channels screws.
  • FIG. 1 shows a perspective view of two wood / concrete composite elements 2, 4, which must be connected to form a wood / concrete composite structure.
  • Each wood / concrete composite element 2, 4, has a concrete slab 6, which runs in the diagram in the xy plane and is significantly longer in the x-direction as well as in the y-direction than they strong in the z-direction.
  • the concrete slab 6 is in the drawing on wooden beams 8, wherein the adjacently arranged wooden beams 8l and 8r are to be connected to create a wood / concrete composite.
  • FIG. 2 now shows, in an enlarged detail view, the two wood / concrete composite elements 2, 4.
  • an insert element 10l and 10r On each of the wooden beams 8l and 8r there is an insert element 10l and 10r.
  • the insert elements 10l, 10r have a flat base plate 12l, 12r which in each case terminate flush with the lateral edge region of the concrete elements 6 extending in the xy direction.
  • the insert elements 10l, 10r have been fastened here with screws not shown here on the wooden beams 8l and 8r before the concrete slab 6 were concreted.
  • This screw 22 is shown in Figure 2 in an enlarged view (relative to the remaining contents of Figure 2) on the left edge of the picture.
  • the empty tubes 14l, 16l and 18r, 20r have a spatial course in such a way that the at the base plates 12l, 12r opposite ends 24 of the conduits 14l, 16l and 18r, 20r entering screws 22 takes a ringweg over the lateral edge regions of the concrete elements 6 goes out, which is shown in Figure 3 and will be explained in more detail below.
  • the spatial course depending on the selected cuboid composite can be characterized by angles of 30 to 60 °. Especially for static reasons and because of the better predictability of the load moments in the three directions of the Cartesian coordinate system, an angle of about 45 ° is selected for the spatial course, as is the case here in the exemplary embodiments.
  • the two empty tubes 14l, 16l and 18r, 20r are provided, which are aligned substantially orthogonal to each other, but have a certain asymmetrical arrangement, so that their through the screw channels pre-drawn screw paths are crossing free.
  • the distance of the empty tube 18r from the lower edge of the base plate 12r is substantially smaller than the distance of the empty tube 20r from the upper edge of the base plate 12r. This can also be clearly seen on the insert element 101 positioned on the other side, the position of which results from the rotation of the insert element 10r by 180 ° in the xy plane.
  • FIG. 3 shows the cutout according to FIG. 2 after a connection of the two wood / concrete composite elements 2, 4 to a wood / concrete composite structure 26.
  • the asymmetrical alignment of the empty tubes 14l, 16l or 18r, 20r is clearly recognizable two with their base plates 12r, 12l abutting insert elements 2, 4 predetermined screw paths essentially the four space diagonals of a cuboid, preferably a cube, describe, the screw paths are crossing free.
  • the screw 22vl is here passed through the empty tube 14l when screwing. Accordingly, the screws 22hl, 22vr and 22hr have been screwed through the empty tubes 16l and 18r and 20r, respectively.
  • Figure 4 shows a sketch of ervous T1 to T4 for a cubic Elemementarzelle with an edge length of 10 cm.
  • the screw T1 to T4 each extend at an angle of 45 ° to all three directions x, y, z.
  • the screw paths T1 to T4 run through the unit cell without crossing (unlike the four space diagonals of the unit cell meeting in the center Z).
  • the ends 24 of the conduits 14l, 16l, 18r, 20r can be closed with a removable, but not shown here lid.
  • the conduits 14l, 16l, 18r, 20r are telescopically adjustable in length in not shown here.
  • FIG. 5 shows, in strong analogy to FIG. 3, a connection of two wooden beams 291, 29r with the aid of an assembly jig 30.
  • the assembly jig 30, unlike in the exemplary embodiment according to FIG. 3, is now configured in one piece and therefore has a substantially square base plate 32, from the (analogous to the embodiment of Figure 3) now more the four conduits 14l, 16l, 18r and 20r protrude.
  • the empty tubes 14l, 16l, 18r and 20r give Here, due to their spatial orientation, the screw paths for the four screws 22vl, 22hl, 22vr and 22hr, wherein the letters attached to the reference numeral 22 represent, through which the conduits 14l, 16l, 18r and 20r, the respective screw was screwed. Also in this embodiment, the diameter of the head 28 of the screw 22 is only about as large as the diameter of the screw 22 itself.
  • openings may also be present in the base plate 32, in which other screws for temporary fixing of the assembly jig 30 on the two wooden beams 291, 29r can be arranged.
  • An alternative or additional fastening method can also be achieved by means of screw clamps. After screwing the four screws 22vl, 22hl, 22vr and 22hr through the four empty tubes 14l, 16l, 18r and 20r, these temporary fixing means can be released again and the assembly jig 30 can be inserted elsewhere.
  • the assembly jig 30 can also be made entirely of metal or a correspondingly stable plastic.
  • the conduits 14l, 16l, 18r and 20r may each be supported in their own position by additional means, for example by supporting webs.
  • additional means for example by supporting webs.
  • other means may also be provided which also support the empty tubes 14l, 16l, 18r and 20r with one another and thus contribute to the stability of the assembly jig 30.
