Definitions

  • the present invention relates to a method of manufacturing a wall element and in particular a ceiling element, consisting of a support frame ensuring the maintenance of a stretched canvas. It also relates to the wall elements obtained by this method and more particularly wall elements of translucent or transparent type.
  • slabs some of which consist of a light frame formed of an aluminum profile on a edge of which is fixed, in particular by gluing, a polyvinyl chloride plastic cloth. , which is previously subjected to a high voltage. It was found that, under the effect of this tension, the amounts of the frame tended to deform inwardly thereof. This is why we are forced, when we want to implement this type of technique, to make frames that either have a reinforced cross section, which increases the cost and weight of the realization, or are equipped with square or reinforcing bars that provide a connection between their adjacent or opposite sides.
  • a wall element of this type has also been proposed in which the frame consists of four tubular elements inside which is arranged a prestressed holding element intended to improve the resistance. bending each of these four elements. If such a device makes it possible, to a certain extent, to prevent the deformation of the sides of the frame, this improvement is obtained in return for a greater complexity of the structure, a higher weight and, consequently, an increase in its manufacturing cost. Moreover, if such a technique is satisfactory for making wall slabs, it is much more difficult to implement on large elements such as wall elements.
  • the present invention aims to remedy these drawbacks by proposing a manufacturing method for producing ceiling elements consisting of a frame supporting a stretched fabric avoiding the type of aforementioned deformations and not using specific reinforcement means likely to harm its aesthetics or increase its manufacturing cost.
  • the present invention thus relates to a method of manufacturing a wall element, in particular a ceiling element, consisting of a polygonal frame on which a fabric is stretched, in which prior to the fixing of the fabric, it is subjected to on each side of the frame a bending outwardly thereof, so as to give it an arrow such that, when fixing the canvas on the frame, the tension exerted by it deforms in the opposite direction said side and returns it to the initial position existing before its predeformation, characterized in that the bending is made at a distance from the ends of each of the sides.
  • the predeformation of each of the sides of the frame will preferably be carried out before the assembly thereof.
  • This embodiment is particularly interesting in that it makes it possible to use methods for obtaining a gradual, regular and controlled deformation of the sides, such as those usually obtained by means of a bender.
  • assembly means of the different sides of the frame consisting of connecting elements at right angles whose branches will respectively be secured to the two adjacent sides of the frame.
  • bending will be performed at a distance from the ends of each of the sides at least equal to the length of the branch of the bracket secured to the frame side concerned.
  • Frames may be of any cross section and preferably of square or rectangular shape. Interestingly, this cross section will preferably consist of a closed line conferring on this side a tubular structure.
  • the subject of the present invention is also a wall element, in particular a ceiling element, of the type comprising a rigid polygonal frame on which a fabric is stretched, each side of said frame consisting of a bending preformed element facing outward before the introduction of the fabric, said frame becoming straight after the introduction of the fabric, said bending being made at a distance from the ends of each of the sides.
  • the present invention is interesting for forming ceilings but it can also be used to make vertical walls using a transparent fabric or not.
  • FIGS. 1 and 3 show a schematic top view of a rectangular ceiling element which comprises a metal frame 1 on which is stretched a sheet 3 of polyvinyl chloride or PVC.
  • the frame 1 is formed of four sides, namely two opposite large sides 5a and two small sides 5b which are connected together by means of securing means which consist of angle elements 7 which are arranged in the corners and whose branches are respectively integral with these two sides.
  • securing means which consist of angle elements 7 which are arranged in the corners and whose branches are respectively integral with these two sides.
  • each of the sides 5a and 5b are subjected to respective forces F1 and F2 which are directed in a direction such that the resultant deformation of the sides produces respective arrows f1 and f2 in the center of these sides which are oriented, after assembly of the frame, from the inside to the outside of the latter.
  • such deformation of the sides 5a and 5b is effected by means of a bending machine, which makes it possible to produce a deformation allowing the sides to have a regular curve. So that the angled elements 7 maintain their angle at the top of 90 ° and, in order not to disturb their assembly with the sides 5 'a and 5'b, it will perform the bending of these sides only to a length l inferior to the total length L of the considered side.
  • the length l ', which is not curved is at least equal to that of the corresponding branch of the bracket 7.
