Description

1 2791117

  The present invention relates to a construction element more particularly, but not exclusively, intended for the realization

  of structure capable of forming the framework of a building.

  The element of the invention is characterized, in its simplest form, by the cross assembly of two bars, preferably identical, arranged so as to extend each on either side of a

common plan.

  Other characteristics of the invention will emerge more clearly from the

  description which follows made with reference to the drawings appended to

  indicative example only, in which - Figure 1 is the top view of an element according to the invention; FIG 2 is the elevational view of the element of Figure 1; FIG. 3 is a view, similar to that 1, showing an alternative embodiment; FIG. 4 shows, on a smaller scale, a structure produced using elements conforming to that of FIG. 1; FIGS. 5 and 6 show alternative embodiments of the structure of FIG. 4; - Figures 7 and 8 illustrate the possibility of making composite elements from two elements conforming to that of Figure 1; - Figure 9 shows a structure made from composite elements conforming to that of Figure 7; FIG 10 is a view, similar to that 4, using elements in accordance with that of Figure 3; FIG. 11 is an alternative embodiment of the element of the invention; FIG. 12 illustrates an example of a composite element produced using elements conforming to that of FIG. 11;

  FIG 13 is a view, similar to that 1, showing another embodiment; FIGS. 14 and 15 illustrate structures produced using

  of elements conforming to that of FIG. 13.

  Referring to Figure 1, we see that the element of the invention is formed by the assembly in cross of two identical bars 1 and 2, each arranged on either side of a common plane whose the trace

appears at P in Figure 2.

  Figure 1 shows a symmetrical element that is to say an element whose branches also extend on either side of the assembly point 3, but it is possible to produce elements

  asymmetrical like that of figure 3.

  FIG. 4 illustrates a structure produced using elements conforming to that of FIG. 1. Only three elements are shown, but it is understood that the aim is to produce a structure in the form of a crown, structure included in a plan. For this purpose, if we consider the elements 10a, 10b and 10c, we see that the branch 12b of the element 10b rests on that 11a of the element 10a and that the branch 12a, of the latter, rests on that 11b of said element 10Ob, and so on for the other elements. The elements are assembled, at the contact points by any appropriate means, final assembly or

removable.

  In FIG. 4, the branches 12a and 11b are in line with one another, but they can form a different angle between them

of 180.

  Figure 5 shows that it is possible, by sliding, to modify the dimensions of the structure, while that 6 shows that it is posible

  to realize a sinuous structure.

  It is possible to produce composite elements from the assembly of two elements, this possibility is illustrated with reference to FIGS. 7 and 8. The principle of assembly consists in attaching laterally the branch 12a of an element to that 12b of the other. By assembling a plurality of elements in accordance with that of FIG. 7, it is possible to produce a structure (see FIG. 9) which can support, for example, a floor or the like. It should be noted that it is possible to slide a composite element relative to another or from th

  rotate to obtain a three-dimensional structure.

  FIG. 10 illustrates the possibility of making a structure in the shape of a left crown, that is to say a structure according to which certain elements are not in the same plane. If we consider the two elements 20a and 20b, we see that the ends 21b and 22b pass under those 21a and 21b of the element 20a. Relative to the plane of the drawing containing the element 20a, that 20b extends partly above

of said plan.

  FIG. 11 illustrates another embodiment according to which the point of contact 3 between the two bars 111 and 112 is situated at one of the ends of these. With the help of such elements, it is possible to produce a composite element such as that of FIG. 12 being pointed out that, the angle A can vary from a few degrees to a value

4 2791117

  close to 180. The choice of the value of this angle depends on the type

of structure to achieve.

  FIG. 13 illustrates another embodiment according to which the element is formed by the assembly of two curvilinear bars 31 and 32. According to another characteristic of the invention, the assembly, at B, of the two bars is carried out by l 'through a means allowing the two said bars to slide and pivot independently of one another. Such a means can be constituted by two superimposed sleeves, each crossed by a bar, of cylindrical section, and being able to pivot one relative to the other along an axis orthogonal to those of said sleeves. FIG. 14 illustrates a crown-shaped structure produced using elements conforming to that of FIG. 13. The ends of branches of the element 30a can pivot along the fixed axes XXi and YY1. It will therefore be understood that if an ascending force is exerted, by any appropriate means on the elements 30 of this structure, a dome-shaped structure is sketched out which will only be maintained

  by firmly fixing the bars 31 and 32 relative to each other.

  Using sleeves as described above, this attachment is not a problem. As shown in Figure 15, we can add to the crown of Figure 14 a second crown, formed of smaller elements, assembled to the previous one, in C, using a means similar to that used to assemble bars 31 and 32. In the case of a sleeve assembly device, a third sleeve will then be used, crossed by the corresponding bar of the lower crown and able to pivot around the same axis as that of pivoting of the two other.

  It should be noted that each bar of an element can be made in two telescopic parts. It should also be noted that the bars

  can be made of an elastically deformable material, and, or, 5 inflatable.
