Definitions

  • the present invention relates to a spatial lattice structure and to the struts used to obtain it.
  • Spatial lattice structures are extremely interesting, being based on the principle of versatility and modularity of the junction nodes and rods that form them. They represent a valid modern architectural alternative solution for the fitting out of trade shows, booths, roofing for sports facilities, industrial and civil buildings.
  • Lattice structures of this type are known and largely used regardless of numerous disadvantages.
  • the spatial lattice structure according to the known art comprises two types of rods: struts that form the bearing frame of the structure, and diagonal rods that complete the lattice structure.
  • junction node indicates the points where struts, and eventually diagonal rods, converge.
  • struts and diagonal rods are assembled in junction nodes with basically spherical connection means where struts and eventually diagonal rods converge. Structures only formed by struts are also available.
  • the configuration of the structure with spherical connection means requires soldering or screwing the diagonal rods and/or struts on the spherical connection means, directly on site, and this is not practical, in view of the large dimensions and weights of the different parts.
  • the assembly collars according to the known art are shaped as an internally hollow prism with triangular cross-section.
  • the assembly collar is soldered at the end of the strut by soldering one side of the prism with triangular cross-section.
  • Soldering is of circular type because it represents the connection of a circular profile, that is to say the strut, with a plane, that is to say the side of the prism with triangular cross-section.
  • Soldering is difficult to perform, being of the so-called "head-to-head” type and can have problems in terms of strength and resistance.
  • Another inconvenience consists in the difficulties encountered to insert the typical bolts and nuts with large diameter inside the small triangular cross- section of the collar, in order to support the heavy loads applied on struts and rods.
  • the purpose of the present invention is to obtain a spatial lattice structure that provides a simple inexpensive solution to the inconveniences of the known structures.
  • the aforementioned purposes are achieved by the present invention with a spatial lattice structure that comprises at least a lattice made of struts, in which the struts are provided at least at one end with a V-notch in which a corner of the assembly collar is inserted and soldered to assemble struts in junction nodes with bolts or similar parts.
  • the struts can have any type of cross-section, meaning a circular, elliptical, square or polygonal cross-section.
  • the assembly collar is advantageously soldered to the strut with a corner and not with a side, in such a way that, if the struts have a circular or elliptical cross-section, soldering develops according to a semi-ellipse, with total soldering length higher than the soldering length of the known art.
  • a higher soldering length ensures a better hold and higher strength of soldering.
  • this type of soldering is easier to make, since it is not of head-to-head type.
  • the collar is shaped as a prism with four or more sides, thus increasing the space inside the collar, and facilitating the insertion and tightening of the bolts and nuts that are used to connect collars to form the junction node.
  • the present spatial lattice structure is simple to make and assemble and inexpensive; in fact, traditional sections can be used to obtain struts, rods and assembly collars.
  • the present invention also relates to a strut for lattice structures, which comprises an elongated strut body shaped as a rod or similar item, provided at least at one end with a V-shaped notch in which a corner of the assembly collar is inserted and soldered to assemble the strut in junction nodes with bolts or similar parts.
  • - figs. 1 A and 1 B are a top view and a side view, respectively, of a strut of the spatial lattice structure according to the present invention
  • - figs. 2A and 2B are a top view and a side view, respectively, of a diagonal rod of the spatial lattice structure according to the present invention

  • the strut (1 ) illustrated in figs. 1 A and 1 B is a strut with circular cross- section.
  • struts (1 ) can have any type of cross-section, meaning a circular, elliptical, square or polygonal cross-section.
  • the strut (1 ) is provided at least at one end with a V-shaped notch (2) in which an assembly collar (3) is inserted and soldered.
  • the assembly collar (3) is provided at both ends of the strut (1 ).
  • the shape of the assembly collar (3) depends on the geometry of the spatial lattice structure; in the executive embodiment illustrated in figs. 1 A and 1 B, the assembly collar (3) is an internally hollow parallelepiped with square cross-section.
  • the assembly collar has a rhomboidal cross-section in the executive embodiments illustrated in figs. 4 and 5, and a circular cross-section in fig. 6.
  • the two free sides of the assembly collar (3) that is to say the sides facing the sides soldered in the V-shaped notch (2) of the strut (1 ), are provided with a fixing means (4) to assemble the struts (1 ) and eventually the diagonal rods (5) in junction nodes, as illustrated in figs. 2A and 2B.
  • the fixing means (4) is a seat shaped as a hole, in which a bolt closed with a nut is inserted and fixed.
  • the assembly collars (3) are shaped in such a way to facilitate the insertion of the bolts used to connect struts with struts and/or struts with diagonal rods, also in case of bolts with large diameter.
  • Figs. 2A and 2B are a top view and a side view, respectively, of a diagonal rod (5) of the spatial lattice structure according to the present invention.
  • the diagonal rod (5) illustrated in figs. 2A and 2B is a diagonal rod with circular cross-section.
  • the diagonal rods (5) can have any type of cross-section, meaning a circular, elliptical, square or polygonal cross- section.
  • the diagonal rod (5) is provided at least at one end with a soldered flat assembly plate (6).
  • the flat assembly plate (6) is provided at both ends of the diagonal rod (5).

  • Fig. 3 is a top view of a junction node (8) of a first preferred executive embodiment of the spatial lattice structure according to the present invention.
  • the struts (1 ) are equally spaced along the circumference with junction node (8) as centre.
