Definitions

  • the present invention relates to frameworks or frameworks of solid volumes and, more particularly, framework structures or trusses for frameworks or frameworks of buildings.
  • the present invention relates specifically to new types of curved portal frames or trusses with structural self-resistance.
  • the subject of the present invention is assemblies of structures making it possible to build, from straight, standard elements, of small dimensions, and made of various materials, farm structures or light and robust frames, for the rapid assembly of curved frames with variable spans intended to receive a protective cover, for example for the production of greenhouses or light covers for swimming pools or gymnasiums.
  • Another object of the present invention is the production of framework structures which can be stacked to form self-supporting hollow solid volumes of various dimensions.
  • a framework or framework of solid volumes comprises at least one frame or truss structure constituted by the assembly of at least two adjacent rows each formed of a plurality of successive, identical elongated structural elements of short length, each row having a general configuration of regular polygon whose sides are formed by said elements, each element of a row being angularly offset by the same an - gle of successive adjacent elements of the other rank by being connected to each of these adjacent elements of the other rank to form a frame structure having the general shape of a regular star.
  • first means for securing each element of a row to the successive adjacent elements of the other row and second means for securing between them the adjacent ends of two successive elements d 'same rank.
  • these second means are arranged to allow the mounting of transverse secondary frame elements or purlins.
  • FIG. 1 represents a farm structure constituted, according to the principle of the present invention, of at least two adjacent polygonal rows referenced I and II, joined to each other, each row being constituted by a successive series of identical straight elongated elements, of short length and made of wood, metal, reinforced plastic or even light concrete.
  • Each element present in the embodiment of FIG. 1 a general trapezoidal shape symmetrical with respect to a median transverse plane 7, and comprises, in the vicinity of each longitudinal end, at least one through hole of end 4, at the level of the median zone between one end and the median plane 7, an intermediate through mounting hole 3, and, on either side of this median plane 7, two central through holes 8.
  • an element such as that referenced A, of rank I is secured, for example by means of a tie rod or a screw-nut assembly such as 9, to two successive adjacent elements, marked B and C, of row II with the holes 3 of the adjacent end parts of the elements B and C coinciding, for the mounting of the screw or the tie rod, with the holes 3 distant longitudinally of the element A.
  • the elements B and C are angularly offset with respect to the element A symmetrically with respect to the median plane 7 of the latter, so that the central holes 8 of the element A coincide, for a fixing by screw or pulling, with the holes of adjacent end 4 of elements B and C, the opposite end holes 4 of element A each being in alignment with one of the respective central holes 8 of the elements associated therewith B and C.
  • next element A 'of the row I is secured in the same way to the associated elements C and D of rank II, and so on, for c create a double structure of two rows I, II juxtaposed, each row achieving the shape of a regular polygon, the sides of which are formed by the constituent elements of this row, the polygons thus formed by rows I and II being offset angularly around a common center to produce a structure with an external profile in a regular star, the successive vertices of which are formed alternately by the opposite ends of successive elements of one and the other rank. Cutouts forming shoulders L are provided in the opposite ends of the elements, to provide a space allowing the mounting of elements of a secondary frame, such as purlins 5, which are secured to the adjacent element of the other row. by at least one jumper 6 mounted in orifices 60, formed in the field of the element on either side of the median plane 7.
  • FIGS. 2 to 4 Another embodiment of such a frame structure is shown in FIGS. 2 to 4.
  • This structure is, this time, made from identical elements 10, of flat parallelepiped shape, on which we find the holes 3 arranged at the median zone between the end of the element and its median plane of symmetry 7 , the assembly of the respective elements of two adjacent rows I and II being similar to that shown in FIG. 1.
  • the adjacent ends of two successive elements of the same row are joined together by means of 'a fitting 11 or 11', having at least one pair of opposite lateral wings 12, pierced with holes to cooperate with corresponding holes 8 ', provided at the ends of the elements, and at least one lower wing preferably a pair of lower wings 13 extending down parallel to the pair of wings 12, at a distance therefrom, and having an orifice intended to be aligned with a corresponding orifice 14, formed in the center of each element 10 for its fixing ation to the latter.
  • certain fittings 11, 11 ′ can only be used to join together the adjacent ends of two successive elements of the same row without being secured to the element next to the adjacent row .
  • each fitting 11 and 11' comprises, coming from foundry or added, a housing 15, 15 'for receiving and fix these faults.
  • a fitting 11 with a cylindrical housing 15 for mounting tubular purlins 5 ' and a fitting 11', with a rectangular gutter-shaped housing 15 ', for accommodating parallelepipedic purlins such as those represented in 5 in FIG. 1. It will be noted in FIGS.
  • each fitting 11 or 11 ′ can be provided with two lower straight pairs 13 symmetrical with respect to the first wings 12 for the juxtaposition of three rows of successive elements, the outer rows being paired to constitute a first double polygon and the polygon of the row interior being angularly offset with respect to this first polygon.
  • FIGS. 5, 6 and 7. Another embodiment of the frame structure according to the present invention is shown in FIGS. 5, 6 and 7.
  • This embodiment is very similar to that of FIGS. 2 to 4, except that, as can be seen in FIG. 5 and in the diagram in FIG. 7, the successive elements of each rank I and II , are interlaced, element A of row I being arranged, as seen in FIG. 5, so as to pass behind element B, but in front of element C, of row II, element C of row II passing in turn in front of the next element A 'of row I, and so on.
  • the elements of each row are, in accordance with the principle of the invention, secured in the vicinity of the two middle intermediate zones between the median plane of symmetry and the ends of the elements with two successive elements of the adjacent row with the opposite holes 3 and secured by a screw and bolt system 9.
  • the iron rures 15 here have only a lower wing 13 'thick corresponding to the thickness of the individual elements which have a parallelepiped configuration, this wing comprising at least one hole 130 intended to be aligned with corresponding holes 80, formed at the ends elements.
  • the corresponding ends of two successive elements of the same row are therefore assembled here not end to end, but overlapping, as can be clearly seen in Figure 5.
  • the corresponding ends of two successive elements of the same row can be joined directly by a screw and nut assembly 9 ′, without the need for a fitting 110 or 110 ', the top thus produced not being designed to receive a breakdown of a secondary member.
  • the fittings 110 comprise, as in the previous embodiment, a cylindrical housing 15 for mounting tubular purlins, or a housing forming a rectangular gutter 15 'for mounting purlins of rectangular section.
  • one of the fittings, for example the ridge fitting 111 may comprise a wing 112 extending up to the adjacent element A ′ of the neighboring row for attachment to the latter.
  • the embodiment with interleaving of the elements increases the mechanical strength of the frame structure and allows a more efficient connection of these elements to each other by overlap compared to the butt connection of the previous embodiment, which also allows folding or articulation of elements of the same row, without having to dismantle the support fittings.
  • This assembly also allows the reinforcement of the frame structure by lateral or vertical stacking of corresponding structures, respectively identical or homotetic, facilitated by the clearance created by the alternating offset of these elements.
  • FIGs 5 and 6 to vary the curve of the structure slightly according to the needs, provision will be made, in place and place, for a single intermediate hole 3, in the vicinity thereof, close holes 3 'always intended to be brought opposite to the corresponding holes 3 or 3 ', of the adjacent element of the other row.
  • the assembly with direct overlapping of the ends of successive elements without the interposition of a supporta fitting moreover realizes a real braiding of the elements and gives the structure additional resistance without affecting its flexibility and its ease of assembly.
  • the embodiment with interlacing furthermore realizes, as can be seen in FIG. 12, a truss structure, the constituent elements of which are progressively offset from the base to the level of the element F so that it normally exists , between the latter and the base or support elements, a cantilever d particularly suitable for the production of light buildings, in particular greenhouses, thus allowing a resumption of the traction forces induced on trusses or frames end by the tensioning of the skin or the cover of these light buildings.
  • Figure 12 there is shown, on the right side, one of these end trusses E and, on the left side, in accordance with another aspect of the present invention, an intermediate truss M for such a structure of light buildings , more specifically greenhouses.
  • FIGS. 8 to 11 show another embodiment of a framework structure according to the present invention, more particularly suitable for the production of closed pseudo-cylindrical structures, for example for the production of basins or small removable pools.
  • each element 100 has a trapezoidal shape symmetrical with respect to a median transverse plane 7 and comprises, on at least one of its lateral faces, two mortises 18 of depth slightly less than the thickness of l element, and extending symmetrically in V, with respect to the transverse median plane 7, the bottoms 180 of the mortises being coplanar and parallel to the longitudinal direction of the element.
  • each mortise is parallel to each other, and they are intended to come to bear, during assembly with an adjacent element of another rank, with, respectively, the upper face 20 and the underside of this adjacent element.
  • two such adjacent elements for example A and B, are assembled in the middle of the timber in an inverted position so that, as seen in this FIG.
  • intermediate elements 101 will be used, of the type of elements referenced B and C in FIG. 9, consisting in fact of two elements 100 joined symmetrically along a longitudinal plane of symmetry H, only the rows d the end being made up of single-sided elements 100;
  • the dimensions of the mortises 18 are determined so as to allow a mutual assembly of two adjacent elements of two neighboring rows with a slight clearance around the intermediate adjoining zones Z, this clearance disappearing completely in the final nesting of the elements under the effect of an inwardly concentric load distributed over all of the elements, thus producing a self-locked structure, by abutting the various shoulders constituted in particular by the small faces of the mortises and the corresponding zones of the upper and lower faces of the elements, without the need for additional fixing means such as bolts or keys, the addition of glue or the need for welding.
  • These assemblies, made on a reduced scale, are particularly suitable for the production of construction sets or even exhibition models.
  • the mortises 18 are arranged so as to converge upwards towards each other, leaving between the small internal faces 19 ′, a bracing surface 21 extending in the plane of the upper surface 20 of the elements.
  • This bracing surface 21, of width e thus spares, between the opposite ends of two adjacent elements of the same rank, a spacing 22 at the level of the vertices of the star of the final structure allowing the establishment of trusses or secondary member elements.
  • this bracing surface 21 disappears, the small internal faces 19 ′ of the mortises connecting along an edge 23, coplanar to the upper face 20 of the elements.
  • the elements can be produced by fitting mortises in wooden parts or directly by molding for plastic or light alloy parts.
