Definitions

  • Handling and transporting these roofs involves first mounting the supporting structure, then deploying the covering surface, fixing it to the structure, and finally tensioning it.
  • the present invention proposes to offer a solution making it possible to avoid the drawbacks of transport and implementation of tensioned roofs, while bringing advantages of esthetics and modularity making it possible to quickly build and on any ground of the covered spaces.
  • the subject of the invention is a roof made of stretched flexible material, characterized in that it consists essentially of six beams, connected to each other, at their ends, by articulated connecting pieces, so as to form three triangles of the same base. two of which, which we will call lateral triangles, have their vertices located respectively on each side of this base, and the third, which we will call ridge triangle, at its vertex located above the planes of the other two, and a flexible material is stretched, on the one hand, between the sides of said ridge triangle and the sides of one of the lateral triangles, on the other hand, between the sides of said ridge triangle and the sides of the other triangle lateral, thus creating a roof in the form of two hyperbolic paraboloids joined along the sides of the ridge triangle.
  • the roof according to the invention is of an extremely simple assembly, since it comprises, as can be seen, only six beams and five articulation means, namely three articulations between two parts and two articulations between three parts.
  • the flexible material of the roof can be fixed permanently, by the appropriate selvedges, on the six beams of the triangles and the assembly does not require any more whereas the positioning of the lateral triangles relative to the ridge triangle, then causing the tensioning of the flexible surface.
  • the fixing of the flexible material on the beams can be obtained by providing them with grooves and the edges of the material of rods with a diameter slightly smaller than that of the cross section of the grooves.
  • the beams are of equal lengths two by two, and, preferably all of the same length, thus giving the three triangles the form of isosceles triangles.
  • This embodiment has additional advantages of simplicity and convenience of storage and transport of the constituent elements of the roof. Indeed, the joints between beams being properly oriented, they can fold in parallel and against each other then occupying minimal space.
  • the roof according to the invention can be carried by any means connecting the four vertices of the two lateral triangles to the chosen support.
  • these vertices are connected to the load-bearing surface by parallel feet, the upper ends of which are connected by articulation to the said vertices.
  • the support legs can, of course, also be against them.
  • Maintaining the beams in position can be ensured by any rigid connection means articulated on the beams and feet of each of the dihedrons of the vertices of the lateral triangles.
  • the ridge triangle ABB ′ is constituted by the two beams 5, 6 and the two lateral triangles CBB ′ and C′BB ′ by the beams 1, 2 and 3, 4 respectively. These three triangles are here equilateral.
  • the vertices BB′CC ′ are connected to the support surface S by feet 7, 8, 9, 10 respectively, the length of which is chosen according to the inclinations desired for the roof. Here the feet 7 and 8 of the same length are smaller than the feet 9, 10 also of the same length.
  • appropriate means of articulation are provided. In At the joint allows the folding of the beam 5 against the beam 6; in B and B ′ respectively the drawdown of 2 and 3 against 5 and the drawdown of 1 and 4 against 6. In C and C ′, respectively, the drawdown of 1 against 2 and that of 3 against 4.
  • Each of the beams 1, 2, 3, 4 has a groove along its edge and the beams 5 and 6 each have two grooves along two of their edges. They could have up to 4 grooves.
  • the flexible surface forming the vault a coated fabric S for example, carries on its edges a rod of diameter slightly less than the cross section of these grooves. These rods are introduced into these grooves so as to ensure, on the one hand, the seal between the beam and the fabric, on the other hand, a connection as regular as possible between the beam and the fabric in order to ensure distribution regular tensions.
  • the beams are held in position by articulated bars 11, 12 forming triangles in each dihedron of the corner pieces B, B ′, C, C ′ and folding back parallel along the beams 1, 2, 3, 4.
  • the implementation of the vault which has just been described is particularly simple since it consists only in unfolding the beams 1, 2, 3, 4, 5 and 6 on the chosen site and then placing the bars 11, 12 ... in each dihedral to obtain, at the same time, the final geometry of the whole and the perfect tension of the flexible surface.
  • the four corners B, B ′, C, C ′ are here located at different heights above the ground, equal in pairs diagonally, depending on the lengths of the feet 7, 8, 9 and 10, which can be telescopic to allow adjustment on the site according to the unevenness of the ground so as to direct the flow of rainwater when several elements are assembled.
  • FIG. 1 Another important advantage of the invention lies in the modularity of the system.
  • the grooves located along the edges of the side beams can be used to introduce a seal between two structures, made for example in the same material as the roof and having identical rods, similarly identical grooves located along the edges of the feet allow the subsequent installation of side panels for use as a closure or partition.
  • Figure 2 clearly shows how it is possible to assemble the elements four by four ensuring the flow of rainwater in the middle of each side of the assembly.
  • the device according to the invention can be made in any dimension, the limit being fixed by the resistance of the materials used for its construction. However, to keep all the advantages of ease of implementation and transport, it will be preferred dimensions compatible with the usual means of transport and masses compatible with light handling equipment.
