Definitions

  • the invention relates to a formwork system for pouring a concrete wall or partition and a method for assembling this system, in which two walls which define between them a pouring cavity are formed by adjoining panels supported by uprights provided with means which make it possible to adjust the balance and the spacing of the walls.
  • panels are used to constitute the walls of the casting cavity. are fixed directly to the interior faces of the uprights. These panels, which can be made of wood, have a limited height (80 cm in approximately), have a variable length and are divided into two or more contiguous parts. These parts are connected by vertical joints, such as for example hinges or sockets. This division of the panels aims to allow their transport in a small footprint.
  • the object of the invention is to provide a system which allows on the one hand the use of economical panels, such as wooden boards, and on the other hand the use of panels intended to be left in place, and this by allowing at the same time the pouring of walls or partitions of any length.
  • the invention as characterized in the claims, achieves this object thanks to the fact that the side members allow the side-by-side fixing of very economical panels, such as wooden planks. This makes it possible to provide, at low cost, a large assortment of panels of different widths, thereby eliminating the difficulty of obtaining the desired lengths of wall or partition.
  • the beams allow the hydrostatic thrust of the fluid concrete to be transferred properly to the uprights.
  • the spacing of the latter can be chosen in an arbitrary manner, since this spacing does not depend on the width of the panels.
  • a pair of wooden planks 10 and 12 ( Figures 1, 2 and 7), parallel and spaced, are placed on a base or other preconstituted base surface. one of the other.
  • the two boards 10 and 12 are arranged at a predetermined distance from one another and with the board 10 parallel and located at a predetermined distance from the baseline LB from one face of the wall or partition to flow.
  • shoring means in the form of tripods 14 (figures there 5).
  • Each tripod 14 is constituted by a frame of profiles which, seen from the side, has a configuration in a right triangle.
  • the substantially horizontal lower side of the triangle is defined by a pair of elements 16, the substantially vertical other side is defined by a pair of elements 18, and the oblique side is defined by a pair of elements 20 or struts.
  • the connection angle zones of the elements 16 and 18 are placed on the board 10.
  • Each of the elements 18 is provided with a lateral leg 22.
  • the two legs 22 also bear on the board 10 and serve to prevent the tripod 14 to tip aside.
  • connection angle area of the elements 16 and 20 is provided with a foot 24 provided with an adjustment screw 26.
  • the screw 26 is used to adjust the plumb of the elements 18, with the aim which will be better clarified by the after.
  • the tripods 14 are placed on the boards 10, 12 so that they are aligned as much as possible.
  • each of them is associated with an upright 28 ( Figures 1 to 5, 7, 9 and 10).
  • Each upright 28 includes a U-shaped element made of robust sheet metal, indicated by 30.
  • the trellis reinforcing structure 32 is welded to the wings of this element.
  • welded members lateral attachment 34 which engage in corresponding attachment members 36 of the parallel elements 18 of the tripod 14.
  • the reciprocal attachment of the members 34 and 36 is carried out so as to retain the upright 28 in an upright station in which the flat outer face 38 of the profiled element 30 is parallel to the elements 18.
  • the elements 18 also carry, near the latching members 36 located higher up, respective pivoting hooks 40 which are intended to engage the latching members 34 to make the connection between the upright 28 and its tripod 14 more solid.
  • Each upright 28 has a length slightly greater than the height of the wall or of the partition to be produced (3.25 m for example).
  • transverse plumb of these uprights 28 is adjusted by means of the screws 26 associated with the feet 24.
  • transverse plumb is meant the plumb in a plane vertical normal to said baseline LB ( Figure 1).
  • each profiled element 30 that is to say in its wall which defines the flat face 38, a series of transverse slots arranged in pairs is provided.
  • the slots of each pair are indicated by 42a and 42b.
  • the pitch of the slots 42a, on the one hand, and the pitch of the slots 42b, on the other hand, are constant.
  • the spacing between the slots 42a, 42b of each pair has a predetermined value, which will be specified further.
  • a hooking lug 44 is constituted by a sheet metal element folded so that it has a housing 46 substantially in a U, having in cross section a square shape.
  • the housing 46 is defined, inter alia, by a pair of sheet metal cheeks 48 and 50. From the free end of the cheek 50 is bent square to the outside a flat tongue 52 which is pierced with a hole 54.
  • a lug 44 is carried out by introducing the tongue 52 into the selected slot 42a or 42b, so that the cheek 50 is applied against the flat face 38 and the hole 54 is on the side of the face interior of the core of the profiled element 30.
  • the hole 54 in this position, receives a retaining pin 56.
  • the lugs 44 in the installed condition are clearly visible in FIGS. 7 and 10. In these conditions the housings 46 are open up.
  • tabs 44 along the uprights 28 at suitable arbitrary intervals, from 30 cm to 80 cm for example, as shown in, inter alia, in FIG. 7.
  • beams 58 are visible in the housings 46 thereof, visible in FIGS. 1, 2, 4, 10 and 11.
  • Each spar 58 comprises a C 60 iron with flat outer faces which are parallel to each other.
  • the cavity of the iron 60 is filled with a square slat made of wood or similar soft material.
  • the slat 62 is retained in the iron 60 by means of nails or screws such as 64.
  • the slat 62 has an accessible face, indicated by 66, which corresponds to the open face of the iron 60 and which is at the same level as the edges of the wings of the latter.
  • the cross section of the side members 58 is preferably square with flat faces, as shown, and the spacing of the cheeks 48, 50 of the legs 44 corresponds to the length of the section side of the side members 58.
  • the two cheeks 48 and 50 have on the contrary, a height greater than the length of said side, in order to be able to receive in each housing 46 at least two beams 58 superimposed.
  • the longitudinal members 58 have a suitable length, from 2 to 4 m for example, so that they can extend at least between two adjacent uprights 28 and arranged at a reasonable distance from one another.
  • the adjacent uprights 28 are connected in this way at least two by two, and this at intervals in the direction of the height of the uprights.
  • a subsequent adjacent upright 28 can be connected by inserting into the housing 46 a lug 44, already occupied by a spar 58, one end of another superimposed spar 58 , as shown in Figure 4.
  • the latter spar may be superimposed, in the same lug 44, on another connecting spar to a still successive amount of the series. According to an alternative, this other end may be applied to the bottom of the housing 46 with a tab 44.
  • a tab 44 in which there are two superimposed longitudinal members 58 will be fixed in the lower slot 42a of a pair of slots an upright, while at its other end the upper spar will be supported by the bottom of the housing 46 with a lug 44 fixed in an upper slot 42b of a pair of slots located at the same level of the pair of slots of the adjacent post.
  • the arrangement of the side members 58 for connecting together the different uprights 28 of the series can be chosen in the manner deemed most suitable.
  • the first result is that of perfecting the alignment of the uprights 28, and this thanks to the rather precise embedding of the longitudinal members 58 in the housings 46.
  • the transverse plumb can be adjusted later using screws 26, if this should be necessary.
  • planar faces 67 of the side members 58 opposite those facing the faces 38 of the uprights in turn define a vertical plane.
  • the longitudinal members 58 thanks to the way in which they are received in the housings 46 of the tabs 44, can slide in their horizontal direction of elongation.
  • the longitudinal members 58 therefore do not have a forced position relative to the uprights 28. This allows on the one hand to choose at discretion the distance between the consecutive uprights 28 and on the other hand not to cause the longitudinal members 58 to exceed the position in which a wall or partition must terminate, for example, in order to be connected to a wall or partition arranged at 90 ° or for continuously executing a wall or partition disposed at 90 °.

  • the veil 76 ends, at its end opposite to the gusset'74, by a pair of flanges 78a, 78b folded at right angles to the veil 76 and on both sides of the latter.
  • a flange 70 is placed on each longitudinal member 58, as shown in FIG. 4, so that the flange 78a tightens the panel 68 between itself and the face 67 , and that the web 76 is pressed against the side of the panel.
