Definitions

  • the present invention relates to a method for producing a concrete-wood composite element.
  • the present invention therefore has the object to solve the problem of connecting wood / concrete composite elements for the creation of wood / concrete composite structures with simpler means and more cost-effective.
  • This method produces the desired result of a shear-resistant, ductile composite of the wooden support structure and the flat concrete slab relative to each other.
  • the reinforced concrete plug can be designed as a cylindrically shaped metallic cladding tube with a cylinder cavity substantially filling high-strength concrete mass.
  • the reinforced concrete plug should in the present case have a substantially cylindrical shape, wherein the concrete plug may also have a conical or frustoconical shape. Also, a bottle-like bulbous shape is possible.
  • the reinforced concrete plug can also have an annular groove, for example for receiving transverse loads during prefabrication.
  • the pot-like hole on the hole bottom with a vertical or laterally extending, emerging from the wooden beam Venting channel is equipped.
  • it can be ensured that when filling the hole with fluid concrete no static air pollution extremely reducing air holes remain.
  • this can be safely avoided such an occurrence of air leaks in the hole.
  • the method can be upgraded to the effect that the cladding tube of the reinforced concrete plug against the concrete mass on one side has a supernatant, wherein in the supernatant slit-like incisions are formed.
  • the reinforced concrete plug can also be formed such that the cladding tube has a projection over the concrete mass on one side, wherein the supernatant has crescent-shaped recesses for supporting a washer or a screw head.
  • the concrete plug can be held with an externally mounted screw in the pot hole or on the wooden structure, whereby a mounted in the concrete plug central hole can be avoided.
  • the screw head or the washer then rest on the crescent-shaped recess and thus hold the concrete plug in its position.
  • FIG. 1 shows a schematic view of a reinforced cylindrically designed concrete plug 2 and a only slightly changed concrete plug 2 ', both of which has a cylindrically constructed metallic reinforcing core 4 in its interior.
  • This reinforcing core is made of a wire mesh, for example, a grid 10mm x 10mm and a wire thickness of 1 mm identifies.
  • the wire here is a stainless steel; but it could also be designed, for example, as black steel or hot-dip galvanized steel.
  • the grid can also be chosen to be smaller or larger than shearing forces (eg 16 mm ⁇ 16 mm or 25 mm ⁇ 25 mm).
  • the wire thickness for example, 1.5 mm or just be chosen according to the static requirements.
  • the reinforcing core 4 is surrounded by a concrete body 6 penetrating it and surrounding it.
  • the concrete body 6 is produced, for example, by the pouring of flowing concrete in a form not shown here.
  • the reinforcing core 4 is thus as Concrete wire cage designed; For example, it can also be configured in multiple layers in the form of a rolled-up wire mesh.
  • the concrete plug 2 has a central, running along the cylinder axis hole 8, in which a screw 10 (as in FIG. 2 shown) can be used and the concrete plug 2 can be mounted on a wooden beam 12.
  • the only slightly modified concrete plug 2 ' has an annular groove 7, which can serve for example for receiving transverse loads during prefabrication.
  • FIG. 2 now shows a first wood-concrete composite element 14 with concrete plug 2 used before concreting FIG. 1 with dimensioning.
  • the wooden beam 12 is first provided and equipped with the static requirements bill bearing pot holes 16.
  • the pot holes have, for example, a diameter of 70 mm and a depth of 30 mm.
  • a formwork (not shown here) may be provided for defining the volume to be filled with concrete.
  • the pot holes 16 are of course on the later concrete layer 18 facing side.
  • a reinforced concrete plug 2 is now fixed in each pot hole 16, wherein the concrete plug 2 protrude from the pot holes 16 and thus protrude into the volume of concrete layer to be created 18.
  • FIG. 3 now shows the starting position at one opposite the Figures 1 and 2 slightly changed procedure.
  • a prefabricated concrete plug 2 is - as in FIG. 3 shown - initially only the Arm istskern 4 inserted into the pot hole 16 and fixed by means of the screw 10 therein.
  • the flowing concrete is poured to create the concrete layer 18 and the entire armor core 4 is cast around the tile concrete. So that no bubbles remain in the pot hole 16, each pot hole 16 has at the bottom of the hole with a vertically extending, exiting the wooden beam 12 vent passage 20th
  • FIG. 5 now shows another reinforced concrete plug 22.
  • This concrete plug 22 includes a cylindrical shaped metallic cladding tube 24 and a cylinder cavity substantially filling high-strength concrete mass 26.
  • the cladding tube 24 has a typical dimensioning an outer diameter of 40 to 60 mm and has a wall thickness from 2 to 6 mm.
  • FIG. 6 now shows a variant 28 of the concrete plug 22.
  • This slightly modified concrete plug 28 can be upgraded to the effect that the cladding tube 24 against the concrete mass 26 on one side a projection 30 (see FIG. 5 ), wherein in the supernatant 30 slit-like incisions 32 are formed.
  • a projection 30 see FIG. 5
  • two crescent-shaped recesses 34 for supporting a washer or a screw head 36 in the supernatant 30 has.
  • the concrete plug 28 can be held with an externally mounted screw 38 in the pot hole or on the wooden structure, whereby a mounted in the concrete plug 28 central hole can be avoided.
  • the screw head 36 and the washer are then on the crescent-shaped recess 34 and thus hold the concrete plug 28 in its position, which in FIG. 7 is shown in the sectional image accordingly.
  • the optionally attached additional screw fuses to prevent lateral twisting of the concrete plug 28 under load , as well as at the same time to avoid any occurring block scissors of the wood between the concrete plug 28, especially at narrower plug intervals.
