Definitions

  • the invention relates to a reinforcement of at least one upper and / or lower horizontal bending reinforcement and shear reinforcement elements for supported on columns flat slabs of steel or prestressed concrete, which in order to increase the carrying capacity of transverse stress zones, in particular punching zones in the area of these zones according to the requirements of the thrust cover is provided in the interior of the flat ceiling extending shear reinforcement elements, and that the shear reinforcement elements are arranged with respect to the longitudinal axis of the supports viewed in a horizontal plane at least approximately radially, and a method for producing such a reinforcement.
  • Object of the present invention is to provide a reinforcement of the type mentioned, which does not have the above-mentioned disadvantages, i. which in the hazardous areas, no risky weld has, in conjunction with which is not in the punching zone located adjacent, adjacent concrete, the lower reinforcement additionally supported, and is extremely simple in training, handling and storage.
  • the subject of the present invention is furthermore a method according to claim 7 for producing a reinforcement according to claim 1.
  • the reinforcement arranged in a ceiling 2 supported on a support 1 has an upper and a lower horizontal bending reinforcement 3 and 4, respectively.
  • the elements of the flat cover 2 with respect to the longitudinal axis 5 of the support 1 are radially arranged shear reinforcement elements 6 provided.
  • the shear reinforcement elements 6 consist, as shown in Figures 1 and 2 It can be seen from upright erect, perforated over its entire surface, preferably made of steel sheets, which extend beyond the punching endangered zone A out and there in non-punching endangered area of the ceiling 2 firmly in the concrete Flat ceiling 2 are anchored, which causes a significantly increased effectiveness of the shear reinforcement elements 6 in the punch-endangered area A.
  • the shear reinforcement elements 6 are supported on the lower and / or upper bending reinforcement 4 and 3 and / or, for example. attached with fastening wires.
  • FIGS. 3 to 6 analog FIGS. 3 to 6
  • arrangements of the shear reinforcement elements 6 are shown in the ground plan.
  • FIG. 3 are the shear reinforcement elements 6 welded together in the center, according to FIG. 4 loosely laid, ie, for example, by means of fastening wires or auxiliary structures attached to the upper and / or lower bending reinforcement 3 and 4, respectively FIG. 5 welded on its front sides with a steel core 7, according to FIG. 6 welded on its front side with a steel tube 8, and according to the FIGS. 7 and 8 by means of a welded on its top, extending over two opposing shear reinforcement elements 6 extending high-strength steel wire 9 additionally reinforced.
  • FIGS. 9 to 17 are shown in plan view respectively in side view different embodiments of inventive shear reinforcement elements 6, wherein the FIGS. 9 and 10 a shear reinforcement element 6 as shown in Figures 1 and 2 see, show, FIG. 11 shows a shear reinforcement element 6 provided with mutually staggered holes 10, FIG. 12 shows a two-part V-shaped welded together shear reinforcement element 6, FIG. 13 one of two about bolt 11 to a pair of sheets assembled shear reinforcement element 6, and FIG. 14 a shear reinforcement element 6 consisting of a V-shaped bent, perforated sheet metal.
  • the shear reinforcement elements 6 according to the FIGS. 16 and 17 are for their preparation in the openings 10 of the sheets according to FIG. 15 Bolt 12 ( Fig. 16) or 13 (Fig. 17 ) and welded to the sheet. In this way, projections for anchoring in the adjacent concrete when used in a reinforcement according to claim 1.
  • the bolt 13 can be like FIG. 17 be seen, for example, be provided with anchoring heads 14 at their two-sided ends.
