Definitions

  • the invention relates to a connector reinforcement element made of a coulter or structural steel mat and at least two bars bent in an angular shape as connecting reinforcement for the main reinforcement of a reinforced concrete structure, wherein one leg of the bars can be supported on the main reinforcement running parallel to it.
  • Ironing mats e.g. B. from AT-PS-346 046 known coulters, coulters and mats with spacers, spacers in snake or other shapes, push ladders and. Developed to name just a few.
  • the object of the invention is to save the above-mentioned additional consumption of steel, to reduce the amount of work required and to enable the connecting reinforcement to be laid exactly, without the risk of displacement during concreting.
  • a connector reinforcement element is to be provided, which makes it possible, after laying the main reinforcement above, not first to install individual bars but rather a plurality of bars combined into elements (coulters or special mats), secondly to securely connect the elements laid in this way to the overhead reinforcement and thirdly, to enable the distance between two rows of plugs, which is predetermined by the wall thickness, to be kept precisely without measuring through the intended stop.
  • this object is achieved in that the bars bent in an angular form are arranged parallel to one another with their other leg on the bar coulter or the structural steel mat and in that the bars of the bar coulter or mat running parallel to the latter leg are bent over the corner of the corner Stick out freely.
  • a preferred embodiment consists in the fact that two angle bars are connected by a cross bar or that two angle bars form parts of an integrally formed bracket. This enables the stop function to be implemented in a simple manner.
  • 1 denotes a family of rods in which the mutually parallel rods 1 'are combined and connected by holding rods 2.
  • 1 to 3 is a U-shaped rectangle on the coulter 1
  • Form-shaped reinforcement bar 3 arranged at both free ends at 90 ° from its plane.
  • the bar coulter 1 with the reinforcement bar 3, as described above, forms a connector reinforcement element, which is designated as a whole by E1 and can be used as a connection reinforcement to any reinforcement network.
  • the length Y1 of the leg 4 "expediently determines the distance between two rows of connector reinforcement elements E1, since then the bars 1 'of the adjacent connector reinforcement element (not shown) rest against the middle part 11 of the bow-shaped reinforcement bar 3 as a stop.
  • the length Y1 of the leg 4 “must correspond to the prescribed or required wall thickness.
  • a connector reinforcement element E2 is shown, which differs from the element E1 of Figs. 1 to 3 in that the central part 11 of the bow-shaped rod 3 is omitted, so that two rods 4 remain, which are bent in an angular shape.
  • the legs of these bars 4 are designated 4 'and 4 "and correspond to the legs of the bow-shaped bar 3 with the same designation.
  • the legs 4' are welded to the bars 1 '. This embodiment saves time by bending, but does not offer a stop for one second connector reinforcement element if two parallel connector reinforcement elements are to be installed.
  • a reinforcement element E3 is formed analogously to the elements described above, from bars 1 ', which are rigid by holding bars 2, i. H. dimensionally stable, connected to one element.
  • Angle bars 4 are provided for fastening the reinforcement element E3 to any reinforcement network. At least two of these rods 4 bent in an angular shape are connected with their shorter legs 4 ′, preferably by welding, to two rods 1 ′ of the set of rods 1. Two angle bars 4 are connected by a straight bar 5, u.
  • FIG. 6 shows two such connector reinforcement elements E3 and E3.1, in the front view in the direction of arrows Pf2 in FIG. 5, the second connector reinforcement element E3.1 being identical to or different with respect to rod diameter E3.1 can be. Installation is carried out as follows:
  • the plug reinforcement element E3 is to be laid in such a way that the horizontal leg 4 "of the angle bar 4 rests on the top reinforcement 8, 9 of a plate.
  • the bar 4 is then closed with the top reinforcement 8, 9, preferably by binding with wire
  • the plug reinforcement element E3.1 can be installed, or in such a way that on the one hand the horizontal leg 4 "of the angle bar rests on the reinforcement 8, 9 above, but on the other hand the element E3.1 in the direction of the arrows Pf3 as far is pushed until the vertical leg 4 'of the angle bar 4 abuts the bar 5 of the already laid element E3.
  • the prescribed distance between the two rows of connectors E3 and E3.1 can be precisely maintained without additional measurement.
  • Fig. 7 shows in section a foundation slab with a rising (vertical) concrete wall in this installation.
  • the plate reinforcement at the bottom consists of bars 6 and 7, the reinforcement at the top from bars 8 and 9.
  • the plug reinforcement elements E3 and E3.1 are first pushed downwards in the direction of arrow Pf4 until bars 2 and 5 attach to the Hit rods 9. Then the element E3.1 is pushed in the direction of the arrow Pf5 until its rods 1 'meet rod 5 of the element E3. The rods 2 and 5 are then bound to the rods 9 with wire. An additional rod 10 can then be inserted parallel to the rods 8.
  • connecting reinforcement is possible within the scope of the invention.
  • more than two angle bars 4 can also be provided.
  • the angle that the legs 4 ′′ to the plane of the coulters 1 or the structural steel mat can also be other than a right angle.
