Definitions

  • the invention relates to a reinforcement according to the preamble of the main claim.
  • the invention has for its object to provide a reinforcement that is suitable to be used in connection with flexible formwork, wherein there are special requirements that the reinforcement cannot come loose when the concrete is poured into the formwork.
  • the invention is based on the consideration that warp mats for underground mine construction are known which, when subjected to pressure from the mountains, lead to an automatic, tensile locking of the mats with one another.
  • the use of such mats as formwork aids, which are now adapted to the new application in terms of their design, has the advantage that when the concrete is poured into the formwork and the pressure then occurs, the mats tighten each other, the through the between the longitudinal and parts of the flexible formwork passing through cross wires formed fields cause the reinforcement to be firmly fixed on the outside of the formwork.
  • A indicates a concrete pillar which has a formwork made of a flexible mat B , this formwork being protected on the outside by three reinforcing mats 1, 2 and 3.
  • Each reinforcing mat 1, 2 or 3 consists of longitudinal wires 4 and transverse wires 5, which are welded together at 6 at their crossing points.
  • the longitudinal wires 4 of the reinforcing mat 1 are hook-shaped o angled in their Endbreich at 10 to about 90 and then bear on their outer side a cross member 7, which is formed by a passage extending over the entire mat width rod firmly welded to the outside of the longitudinal wires 4 is.
  • a crossbar 9 lies freely against the back of the longitudinal wires 4. In its end region it is bent onto the inside of the reinforcement mat 1, 2 or 3 and welded firmly to the longitudinal wires 4.
  • each reinforcement mat 1, 2 or 3 hooks 8 are provided, which can be achieved by simply bending back the respective longitudinal wire 4.
  • a tensile connection of the reinforcement mats 1, 2 and 3 to be connected takes place when pressure is applied due to the concrete A filled in the formwork B.
  • the forces exerted by the hooks 8 on the crossbar 9 cause the hooks 8 to be closed in a loop-shaped manner in connection with the cross element 7, so that the connection thus created is able to transmit tensile forces up to the tensile strength of the longitudinal wires 4.
  • the longitudinal bars 4 are bent or slightly angled, so that - as the drawing shows - through the interaction of the different mats 1, 2 or 3 and the corresponding bend the profile of the pillar can be achieved.
  • the number of longitudinal wires 4 depends on the height of the pillar, but it is also possible to place several mats on top of one another.
