Definitions

  • the present invention relates to an anchoring node of a plurality of tubes or metal bars usable for the assembly of a construction work, an interior decoration or a game of assembly.
  • nodes constitute the most important elements for the stability and for the functional arrangements of the buildings thus produced. These nodes must in fact take over not only the load of the constituent elements of the structure but also various external stresses, in particular those due to the wind.
  • the nodes consist of metallic parts of geometric shape adapted to the orientations which the tubes or the bars to be assembled must take, these being then joined by means of several bolts or by welding.
  • assembly is slow and complicated due to the multiplicity of attachment paints.
  • shape of the nodes used hardly lend themselves to large variations in the directions of the elements to be assembled.
  • the present invention aims to remedy these drawbacks by providing anchoring nodes offering multiple directional possibilities for the tubes or bars to be assembled, ensuring effective stability and maintaining the various elements e :. place by a single fastening means, which allows to accelerate the er er assembly. giving it great flexibility.
  • the invention relates, in fact, to an anchoring knot of a plurality of tubes or metal bars usable for assembling a three-dimensional structure for a work ie construction or interior decoration, said node con- s istant in a full spherical assembly comprising a central component forming the core node and a middle portion of the surface of the sphere, surrounded by a number of shells forming in the sphere an upper dome and a lower dome, the various parts constituting this set being molded from a hot-pourable alloy into shapes with non-rectilinear edges capable of integrating tightly and firmly with each other by producing a coherent solid sphere: nais however, leaving a multiplicity of penetration orifices and bearing and retaining surfaces for nipple ends each secured to one of the tubes or one of the metal bars to be assembled, the whole being made coherent by a single fixing means.
  • good cohesion is ensured between the central core and the shells by giving the edges and the contact surfaces of the central part and the shells a more or less sinusoidal outline. This prevents parts from sliding over each other.
  • the central part can be surrounded by two to four shells forming upper and lower domes.
  • the penetrations of the nipple ends which extend along the tubes or the bars are made by superimposing notches specially provided for this purpose in the parts of the central part and of the shells surrounding the outer surface of the sphere. These orifices have a diameter slightly greater than that of the end of the end piece (before the nipple) and are followed in the knot, at a distance sufficient for solidity, by a more spacious cavity making it possible to house and retain the tip nipple. It goes without saying that said tips must be placed in the knot before the final closure of the spherical knot.
  • the means of closing the node that is to say the means of single fixing of the various elements of the assembly, consists of a submerged bolt or a quick fixing ("clips") placed so as to penetrate all the elements.
  • the single means of fixing the various elements of the assembly can be produced by welding.
  • the various elements of the knot are molded from a hot-cast alloy.
  • ends of the tubes or bars to be assembled have a stud connected via one beveled surface to a cylindrical part itself connected to a frustoconical part associated with the tube or the bar. This provides better resistance to forces and facilitates the self-locking of the tips.
  • the anchor nodes of the present invention can in particular be used for the assembly of tubes or metal bars forming the frame of a construction. They can also be used for the erection of greenhouses or halls of all kinds, in particular industrial halls, school yards, etc. They can also be used to create a three-dimensional structure for interior decoration.
  • Figure 1 shows an anchor node of the invention, closed but not connected to tubes or bars.
  • the central part or nc y au of node 1 the upper dome 2 and the lower dome 3. All these elements are made, for example, of steel or nylon.
  • the hatched surfaces 4 indicate the holes for penetration of the end pieces, holes formed by the superposition of notches provided for this purpose in the central part 1 and in the domes 2, 3.
  • Figure 2 gives a perspective view of the node of the invention, the upper dome 2 being raised to facilitate the vision of six end pieces 5 of metal tubes 6 anchored in the node. Two other end pieces, not visible in this figure, are also connected on the other side of the node (see Figure 6).
  • the shape of the end pieces 5 frustoconical part connected to the tube 6, followed by a cylindrical part and a stud connected to the cylindrical part by a bevelled surface which improves the resistance to the forces and facilitates the self-locking tips.
  • the nipples of the tips are larger than the penetration holes and feels retained therefore, after closing the node, by the thickness 7 left between the surface of the sphere and the housing of the nipple.
  • Figure 3 shows, in vertical section, the central part 1 of the node of Figure 2 along the AAAA plane. There are two tips 5.
  • the axes 8 are the axes of slashes. This central part constitutes the core of the node and is full.
  • FIG. 4 represents, in vertical section, the upper 2 and lower 3 domes of a node of the invention. It also shows the bolt 9 and its tightening nut 10 which, by themselves, ensure the closure of the cohesion of the node.
  • Figure 5 shows the central part 1 of the node of Figure 2 in an oblique section made along the plane BBBB of Figure 2. We see the ends 5 of the oblique bars and, in broken line, the passage for the tightening bolt .
  • Figure 6 shows the node of the invention, in plan view, upper dome removed, connected to eight tips.
  • the end pieces 5 1 are those of the horizontal tubes and the end pieces 5 "relate to oblique tubes.
  • the invention is obviously not limited to the embodiment which has just been described.
  • We can vary in particular the number of shells, the shape of the separation path between the elements of the node, depending on the desired angles for the bars, the number of holes for penetration of the tips and their orientation, the nature of the castable alloy hot used for molding elements, etc.
  • the dimensions of the nodes can vary according to their destination and the number of tubes or bars they must connect; this notion is independent of the principle of the present invention.
