Definitions

  • the invention relates to a reinforcement consisting of at least one upper and / or lower horizontal bending reinforcement and shear reinforcement elements for flat slabs made of reinforced or prestressed concrete supported on supports which, in order to increase the load-bearing capacity of zones subjected to shear forces, in particular zones prone to punching, meet the requirements of shear coverage in the area of these zones is provided in the interior of the flat slab extending shear reinforcement elements, a shear reinforcement element for such shear reinforcement, and a method for producing such reinforcement.
  • shear reinforcement elements have the disadvantage that they are almost as expensive to manufacture if they are designed for use in the lower load range as if they are designed for use in the upper load range, and that their shear reinforcement bar density cannot be changed after the manufacture of these elements .
  • the object of the present invention is to create a reinforcement whose shear reinforcement elements, in particular for the lower load range, are very simple and inexpensive, e.g. from a wire or tape reel, continuously producible and after their production can be easily adapted to their use in different load ranges by changing the winding spacing or the helix pitch.
  • the present invention furthermore relates to a shear reinforcement element for insertion into a bending reinforcement, and to a method for producing a reinforcement according to claim 1 by means of shear reinforcement elements according to claim 5.
  • FIG. 1 shows a side view of an embodiment of a shear reinforcement element 1 made of round material (steel) and in FIG. 2 an embodiment made of flat steel.
  • the embodiment made of flat steel has the advantage of a wider supporting surface in the concrete surrounding it when it is concreted in.
  • flat ceilings 3 are in the area of these zones in accordance with the requirements of the thrust cover in order to increase the load-bearing capacity of zones subjected to shear forces, in particular zones subject to punching shear the flat ceiling 3 arranged shear reinforcement elements 1 are provided, for example are attached accordingly by means of fastening wires on the underside of the upper horizontal bending reinforcement 4.
  • FIGS. 6 to 14 show three further exemplary embodiments of shear reinforcement elements 1, each of which is firmly connected to a mounting iron 5.
  • the assembly iron 5 serve to fasten the prefabricated shear reinforcement elements 1 by means of wires 6 to the upper bending reinforcement 4, as is e.g. 13 and 14 can be seen.
  • the reinforcement also has a lower bending reinforcement 7.
  • the assembly iron 5 are welded to the associated shear reinforcement element 1, and it is also conceivable that the shear reinforcement elements 1 are provided with anchoring irons additionally welded to them for better anchoring in the concrete.
