Definitions

  • the present invention relates to angles for formwork, and more particularly those which make it possible to form formwork serving as concrete molds for the manufacture of posts, pylons or the like. It also concerns a process for producing formwork using angles of this type.
  • Angles are already known which make it possible to form forms serving as molds for the production of concrete parts, in particular of substantially parallelepiped shape.
  • Such angles are essentially made up of two branches forming a dihedral with a salient angle, for example at an angle, and means for holding or hooking these two branches with a whole set of other most diverse elements.
  • angles and at least three boards makes it possible to form a prismatic formwork by arranging the boards against the branches of the angles, their edges joining along the edges of the dihedra defined by these branches, and by surrounding with a hoop the angle-plank assembly so as to keep them tightly tight, thereby defining a substantially prismatic space with a triangular, rectangular, square base, etc. depending on the number of angles and boards used, in which concrete can be poured to constitute, for example, a post or the like.
  • the present invention thus aims to achieve a formwork angle which allows to overcome the drawbacks of those of the prior art as described above and which facilitates the production of forms as well as their disassembly.
  • the present invention relates to a formwork angle, comprising two first and second branches forming a dihedral of non-zero projecting angle, a third branch integral with at least one of the other two said branches and a through hole produced in said third branch, characterized in that the axis of said breakthrough is substantially parallel to the edge of the dihedral defined by the first and second branches.
  • Figures 1 to 3 show three respectively front, top and side views of a preferred embodiment of an angle for formwork according to the invention.
  • This formwork angle 1 has two first 2 and second 3 branches forming a dihedral 4 with a non-zero salient angle 12 and intersecting along the edge 5 of the dihedral.
  • These two branches 2 and 3 are generally planar and form an angle different from a plane angle. In the embodiment illustrated in the figures, this angle is equal to ninety degrees, which allows to produce, as will be explained below, formwork for the construction of posts, beams or the like in a rectangular parallelepiped shape.
  • This angle iron 1 further comprises a third branch 6 secured to at least one of the other two branches 2 and 3 and a through hole 7 made in this third branch 6 so that its axis 8 is substantially parallel to the edge 5 of the dihedral 4.
  • the third branch 6 is located in the bisector plane 9 of the dihedral 4 and it is therefore integral with the other two branches 2 and 3, in their parts 10 which meet at the edge 5.
  • This third branch 6 is located in the re-entrant angle 11 defined by the dihedral 4 so as to allow the establishment of the strapping link mentioned below.
  • the through hole 7 is made in the third branch 6 at its second end 18 opposite the first 17 which is linked to the two branches 2 and 3, and the external face 19 of the second end 18 of the third branch 6 is advantageously curve to facilitate the passage and maintenance of the strapping link.
  • the formwork angle 1 further comprises means 20 for fixing a spacer on at least one of the first 2 and second 3 branches, and advantageously on both as in the embodiment illustrated in the figures.
  • fastening means 20 of a spacer on at least one of the two branches 2, 3 are advantageously constituted by a stud 21 integral with one face of the branch 2 or 3 on which the spacer must be fixed and by a orifice 22 advantageously tapped made in this stud.
  • FIGS. 1 to 3 make it possible to produce formwork for pouring, for example, full posts of rectangular parallelepiped shape and are particularly advantageous for casting such posts in a vertical position, at the same place where they must be in place.
  • the embodiment of a formwork for the production of such a post using angles according to the invention is described below with reference to FIGS. 4 and 5.
  • each panel 31, 32, 33, 34 is assembled to form a vertical rectangular parallelepiped 35 so that their edges are advantageously in contact with one another, for example by the face 36 of one and the edge 37 of the other. These panels are temporarily held in this position by any means.
  • sets of four angles 101-104 are placed in planes 41, 42, 43, ... regularly spaced from each other, as illustrated in Figure 5, so that each angle follows the corners of the panels in contact.
  • Each set of four angles 101-104 is surrounded by a link 44 which passes over the curved external face 19 of the second end 18 of each third branch.
  • a link can for example be constituted by a relatively flexible but solid metal strip and allows the angles to be well maintained on the corners of the panels in contact and against the panels, and to form the desired parallelepiped space 35, as appears on the Figures 4 and 5.
  • spacers 46, 47 ... such as plates or the like, can be arranged between two angles 201-202, 202-203,. .. the edges of which are aligned, the two ends 48, 49 of a spacer plate 46, 47, ... being respectively held, for example by screwing, on a stud 21.
  • angles reach substantially to the ground 54 while being guided, that is to say in complete safety for the people in the vicinity.
  • the worker continues his work by removing the strapping from the set of four angles located just above the first which has been uncoupled. The angles also fall towards the ground 54 by superimposing themselves on the previous uncoupled angles. The sets of four angles are thus uncoupled until the last and all the angles are released while remaining gathered on the four rods. They can thus, before being easily retrieved, retain the panels sufficiently to prevent them from falling before completely releasing them, whereas, in the prior art, panels and angles fell on the ground in a completely random manner and risked even, in their fall, to injure the workers present.
