Definitions

  • the present invention relates to a metal frame for reinforced concrete.
  • metal reinforcements for reinforced concrete hot formed, in the form of bars, with an oval cross section, provided with oblique ribs each extending over approximately 180 ° from the periphery of the bar, the inclination of said ribs. about the axis being about 60 °.
  • the rollers of the latter subject the bar to torsional forces generating in the latter stresses which are released when said bar is subsequently subjected to a folding force.
  • the frame, object of the present invention which remedies these drawbacks are remarkable in that the core of the frame has a square section and has on each of its faces inclined ribs extending over a little less than 90 °.
  • the frame has a central core l, the cross section of which assumes the shape of a square, the vertices 2 of which are truncated, defining four lateral faces 3 each having ribs 4 oblique with respect to to the axis XX l of the armature and extending over a little less than 90 °.
  • the angle formed between the ribs and the aforementioned axis is of the order of 25 ° to 45 °.
  • the assembly is substantially in a circle and the vertices 2, truncated, are rounded.
  • the distance Dl separating the center C of the frame and the apex of the rib is slightly less than that D2 separating said center and an apex 2 of the core. In this way, the contacts between the frame and the V-shaped section rollers or the rotating frames of the straightening machine, are made at the vertices 2, which prevents crushing of said ribs.
  • the ribs of two adjacent faces are associated in pairs so that the apex of each rib on one face is contained in an oblique plane passing through the apex of a rib on the other face.
  • the trace of one of these planes appears in YY i in Figure 1.
  • the ribs of the other two faces are inclined in opposite directions.
  • the faces of the core are slightly curved.
  • the sections of the armature are substantially uniform and are inscribed in a circle.
  • the reinforcement bar can have a polygonal section with n sides defining n faces each having, or some of them, ribs similar to those 4.
