Definitions

  • the invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a cantilevered outer part, consisting of an insulating body to be laid between them with integrated metallic tensile, compressive and transverse force rods which extend transversely to the insulating body and through it in the case of the tensile and transverse force rods protrude on both sides into the components to be concreted, whereas the pressure rods are aligned at both ends with the sides of the insulating body and the transverse force rods run obliquely from top to bottom through the insulating body from the building side and then in the area of the pressure zone protrude towards the cantilevered outer part to be concreted.
  • each insulating body is equipped with several horizontally continuous tension and compression rods and with diagonally installed shear force rods, the number of reinforcing bars depends on the length of the insulating body and on the forces to be transmitted between the subsequent concrete parts. While the tensile and transverse force rods must protrude from the insulating body so that a sufficient overlap with the connecting reinforcement of the components adjoining on both sides is ensured, the compression rods can close with the outer sides of the insulating body.
  • the object of the present invention is to improve the component described at the outset by cost-effective measures in such a way that the risk of flaking at the joint of the pressure rods with the adjacent concrete components is reliably eliminated.
  • transverse force bars arranged in the vicinity of the pressure bars are bent downward in the area of the part of the building to be concreted and, crossing the neutral zone, enter the pressure zone by further turning and then run back towards the insulating body, its deepest Area under which the pressure bars run.
  • the invention is therefore based on the basic idea of giving the shear bar, which previously only ran in the tensile zone of the building part, a further function by bending it down and back to the insulating body so that it forms a concrete reinforcement in the pressure area of the pressure bar .
  • the splitting tensile forces introduced into the concrete by the compression rods are absorbed by the bent region of the transverse force rod and the feared breaking out at the joint is excluded.
  • the solution according to the invention is characterized by low costs, because no additional parts are required, but only the already existing transverse force bars need to be shaped and laid differently.
  • the shear bars in the area of the part of the building to be concreted expediently have approximately the shape of a 3/4 oval. In terms of manufacturing technology, it is most advantageous to bend the bars into a closed or almost closed circular ring shape.
  • the bent end of the shear force rod can run a bit into the insulating body, so that it does not get caught with on-site reinforcement bars or prevent accidental bending.
  • it can be welded to the diagonal central section of the transverse force rod.
  • the transverse force rod In the opposite area of the transverse force rod, that is to say in the region of the projecting component, the transverse force rod has previously been running in the vicinity of the pressure rod, so that the risk of breakout is lower here. Nevertheless, for safety reasons it is also recommended to lower the shear force rod so that it runs below the level of the pressure rod and causes a more effective strengthening of the pressure range in the concrete. It is particularly advantageous if the transverse force rod is then bent upwards out of the pressure zone and runs at least into the neutral zone of the projecting concrete component, it also being possible for it to be hook-shaped at its end.
  • the transverse force rod may also be expedient to allow the transverse force rod to run in mirror image as on the opposite side, that is to say that it comes from the pressure zone and is bent upwards and, crossing at least the neutral zone, runs back towards the insulating body by at least a further bend and there with is connected to the opposite end or to the central region of the transverse force rod.
  • the shear force rod then has approximately the shape of a horizontal figure eight and represents a self-contained system for shear force absorption. This not only gives the pressure range in the concrete a strengthening on both sides with the possibility of transferring positive and negative shear forces.
  • the transverse force bars run at a lower level than before in their lower region and, as a result, their concrete coverage is also significantly less. It is advisable to make the shear bars from stainless steel throughout so that the inevitable oxygen diffusion cannot cause corrosion. In this case, the concrete cover can decrease to zero.
  • the pressure rods often have a cross-sectional widening at their ends in order to reduce the Hertzian pressure occurring at the joint.
  • bell-like pressure pieces are used which are open to the outside and are flush with the insulating body at their edge.
  • the transverse force rods should be pulled down so that they run at least in the lower area of these bell-like pressure pieces or even below.
  • the insulating body 1 carries a series of shear bars 4, which serve in the usual way to absorb the vertical weight of the projecting outer part.
  • shear bars 4 serve in the usual way to absorb the vertical weight of the projecting outer part.
  • FIG. 1 It can be clearly seen in FIG. 1 that the vertical tensile stresses which are triggered by the pressure rod 3 on the building side and which have occasionally led to flaking on the end face of the building-side concrete slab are absorbed by the transverse force rod.
  • the shear bars are, of course, for this purpose 4 always arranged in the immediate vicinity of the pressure rods 3, as is clear from FIGS. 2 and 3.
  • the insulating body In the exit area of the transverse force rods 4, the insulating body has cutouts 1 a of approximately 1 cm depth. As a result, the shear bar is reliably enclosed in the concrete in the bending area.
  • the transverse force bars On the side facing the projecting outer part B, the transverse force bars always emerge from the insulating body 1 in the lower region and there form the desired support of the concrete against the aforementioned chipping forces. It is only necessary to ensure that the transverse force rod is arranged here, just like on the other side of the insulating body, somewhat lower than usual so that it falls below the level of the pressure rods. The transverse force rod is then expediently bent upward and runs out in a hook-like manner, as is illustrated by section 4c.
  • Figure 4 shows an alternative design, in which the transverse force rod 4 on the side of the projecting part B is bent similar to that on the side of the building A.
  • the transverse force rod has the shape of a lying figure eight with two approximately vertical loops 5 and 6, which on both sides from the Protruding insulating body 1 while the crossing area lies in the insulating body.
  • the ends of the shear bar are welded together, expediently by an overlap in the concrete area, not shown in the drawing, that is outside the insulating body 1.
  • the component can be installed on both sides and at the same time is characterized by a particularly high transverse force absorption, so that the splitting tensile forces emanating from the pressure elements are also reliably absorbed.
