Definitions

  • Document FR-A 2 352 928 relates to a reinforcement module comprising several frames in the general shape of a U, parallel to each other and on the lower branch of each of which are fixed two lower struts. Each open edge of the frame is associated with a closure element on which are fixed two other threads or upper threads.
  • the object of the invention is to propose a reinforcement module of simple shape of straight tube with U-section, which is of simplified manufacture compared to the known prior art, thanks in particular to a noticeable simplification of the assembly phase.
  • this module of the type comprising a series of generally U-shaped frames arranged parallel one behind the other and on the lower branch of each of which are fixed two lower ropes, two upper ropes being intended to be associated at the side of each frame opposite to that equipped with the lower struts, is characterized in that at least two frames from the series of frames are double, each of these being arranged so that the upper parts, constituting the ends free of the two vertical branches of the U, are arranged in a complementary and elastic manner so as to allow the two upper strands parallel to the first two to be wedged therewith, integral with the lower branch, and respectively vertically vertical to each of these.
  • a module 1 according to the invention is a metal frame for reinforced concrete, with a general U-shaped section.
  • Each double frame 6 is composed of two 5 E 8 frames, placed side by side or very slightly apart, made of steel wire with elasticity, hardened by wire drawing as is the case for frames 5.
  • the 5 E frames are identical to the frames 5.
  • the frames 8 comprise, from bottom to top in FIG. 1 for each of their two lateral branches, successively a first straight part 9 and returning in a gentle slope towards the inside of the frame, then a second substantially vertical part 10 , then a last rectilinear part 11 which widens abruptly towards the outside as shown. Between each part 11 and the corresponding curved branch 7 of each free end of the frame 5 E is then provided a space 12 in which one of the two upper strands 14, 15 can be elastically wedged.
  • FIGS. 3 to 6 another example of application of the basic module of FIG. 2, allowing the fabrication of a metal frame for beams of rectangular section and of fairly large width.
  • the following operation consists, without moving the module 16, of engaging the module 1 in the latter as shown in FIG. 4.
  • the module 1 is then rotated to align it with the module 16, then, after having removed its two re-entrant lateral branches (9-11 in FIG. 1), it is pulls to the right in the drawing to embed the two right-hand threads 17,18 of the module 16 in the brackets 7, and then the two re-entrant branches are released to cause the two threads 17,18 to be jammed as we had, for the realization of Figure 1, stuck the two strands 14,15.
  • This last operation takes the form of the final position shown diagrammatically in FIG. 6, where the module 1 is keyed onto the module 16 to form an armature 31.
  • FIG. 7 shows how the modules 1 of the invention can be packaged by fitting into each other, eight modules being shown in this drawing. Thanks to the double frames 6, the modules cannot hang on to each other, so that their use is greatly facilitated. Furthermore, the modules can thus be transported in reduced volume, which constitutes an appreciable advantage.
  • FIG. 8 shows a frame 30 for a wide U-shaped beam produced by assembling five modules 1 of the invention, all of square shape in this example, that is to say of lateral branches of the U of the same length as the transverse branch of this U.
  • FIG. 9 shows an armature for a part with an approximately S-section, produced by assembling 32 of four modules 1, also each of square appearance, and of a conventional element 19 with an equilateral triangle section.
  • FIG. 10 shows a frame for a section with a staircase section, produced by assembling 33 of seven modules 1 according to FIG. 2, of a similar module 20, but with a square appearance instead of rectangular, and a module 21 of the prior art, with square section.
  • FIGS. 11 and 12 a module, quite specific but in accordance with the invention, intended to form the frame of a beam with six threads, and with frames distributed in a non-uniform manner for normally more variable cutting forces. important towards the two ends of the beam only in the middle.
  • beams in particular comprise a base 23 formed by two parallel struts 22, with curved ends, and assembled by crosspieces 24 to form a sort of ladder.
  • base On this base are normally welded rectangular metal frames, irregularly spaced to be denser at the ends, two other threads 25 then being welded to the frames.
  • the extensions 11 E furnished with end pieces 26 allow the module to bear, at the time of pouring, on the side panels, and thus rigorously wedge the reinforcement in position.
  • the plastic tips 26 make it possible to avoid the installation of orange buffers between the frame and the forms.
