Definitions

  • the object of the invention is to provide these methods with a method, self-supporting screens and installations making it possible to improve their efficiency.
  • the self-supporting mold banks have a metal frame furnished with shells capable of taking charge of the tensioning efforts, equipped with mobile and self-supporting screens and, in certain cases, group tensioning devices, frame can be provided with rolling means.
  • the mobile and self-supporting screens, the group setting-up and tensioning devices and the self-supporting benches of molds, described above, make it possible to improve, on the one hand, the load-bearing structures of the molds and, on the other hand, the concrete hardening and demoulding facilities for the various processes.
  • the mobile and self-supporting separation screens Es (FIGS. 5 and 20), provided, in certain cases, with temporary fixing means relative to the molds, are constituted in the same way as the head screens, without obviously being provided with means anchoring and hanging.
  • the group tensioning devices by deformable parallelogram MT2 (FIG. 13), comprise a multitude of skies 20, provided with hooking means 21, head screens, linked by ordinary articulations 22, to a series of connecting rods 20a , for fixing by articulation at the ends of the structure for taking charge of tensioning forces, and on the other hand for locking means 23, so that the assembly described works as a deformable parallelogram which, in the stretched position, is self-locking and which, by unlocking, ensures the slow relaxation of the armatures, facilitates demolding and frees the head screens which thus remain pressed against the ends of the demolded products.
  • the devices for tensioning by sliding in parallel MT3 include a few sliding beams 24, of high resistance, provided with hooking means 25, and locking means 26, head screens, and a few parts 27 , sliding, beams linked via one or more rods 28, provided in particular with screwing means 29, to arms 30, fixed at the two ends of the benches or self-supporting structures, using removable means 31 , so that, by the screwing operation of the rods, the group is tensioned and so that, by unscrewing, the prestressing forces are taken over by said self-supporting screens which remain thus pressed against the ends of demolded products.
  • FIG. 8 shows a chain equipped with self-supporting mold benches provided with own rolling means, benches moving on rails in a manufacturing circuit, in horizontal plane, closed by means of two head conveyors 57, so as to pass the molds filled with concrete and closed by means of covers C, through two adjacent chambers F1, of intensive heating in a tunnel and to present them at the demolding station from below an installation D1, consisting either of an overhead crane, or in particular of a gantry 58, equipped with a?
