Definitions

  • This application relates to a triangular, supporting modular structure for constructing trellis geodetic vaults; be they cloister vaults; barrel vaults or spherical domes.
  • trellis geodetic vaults be they cloister vaults; barrel vaults or spherical domes.
  • US Patent 4009543 describes a geodetic vault made by joining a large and a small triangular frame together, and having the features of the preamble of claim 1 or 3.
  • each frame has a flange and are connected by means of three "V" shaped couplings which make up the three vertices of the triangle.
  • Adjacent triangles are connected by means of bolts which fix the adjacent flanges of the adjacent bars.
  • Each side of the reticule of the geodetic vault consequently consists of a pair of adjacent, bolted tubular bars belonging to two different adjacent triangles.
  • the object of the US-A-4009543 disclosure was to design a triangular modular frame which could be connected to the adjacent frames at their vertices and not at the bars, for constricting geodetic vaults.
  • the object of the present invention is to design a new modular supporting structure for vault constructions being simple and inexpensive to construct, fast to assemble, easy to transport thanks to reduced sizes and weight, and being versatile, i.e. easy to adapt to the most varied requirements with the possibility of easily extending or reducing the same in the future.
  • the above joint elements consist of thick box shaped sheet plate sleeves whose cross section has a "U" profile.
  • the base of this "U" shape forms, which the two parallel and opposite sides, an angle equal to the half of the "alpha” angle corresponding to the angle at the centre of each circular section in which the geometric circle of the roofing vault is subdivided for the construction of trellis vaults.
  • Two half-sleeves as above are fitted at the two base vertices of the modular structure, the length of these being equal to half of the top sleeve which is obviously upside down with respect to the base half-sleeves, so that the ends of the two slanted bars can be filled and bolted into the parallel and opposite sides of the two sleeve and of the base half-sleeves, at the top and at the bottom respectively.
  • a shelf is welded under the central side of the base half-sleeves, the same being turned towards the inside of the triangular frame and ending with a transverse tubular spacer which perfectly fits into the horizontal tubular bar of the modular structure in question. At the two ends of this bar there is a hole for the bolt which passes the above tubular spacer to fix both half-sleeves to the base bar.
  • two base half-sleeves being part of two adjacent modules are positioned precisely over a top sleeve being part of a third module under the above adjacent modules.
  • each sleeve is fixed firmly to the two overlying half-sleeves by means of a pair of bolts which pass the matching and superimposed bases of the sleeve and half-sleeve.
  • the same consist of a pair of gusset plates in which the ends of the bars are inserted and bolted.
  • the sizes and shape of the top pair of gusset plates, in which the two slanted bars of the triangular frame join, are obtained by positioning the two base pairs of half-gussets next to each other.
  • the bottom edges of the half-gussets are bent around a horizontal axis to form an "alpha" angle equal to the angle at the centre of each circular section in which the geometric circle of the vault is divided for the construction of trellis "vaults".
  • the two top gusset plates are characterized by a double 90° horizontal bend of their upper edges, which are consequently parallel but closer with respect to their lower edges, so that at each node of the trelliswork realized using several modular structures as described above, a male and female type coupling occurs in such a way that the upper edges of each pair of top gusset plates exactly fits into the bent lower edges of two pairs of base half-gusset plates being part of two adjacent modules.
  • the final fixing between the top and base joint elements can be made by means of a pair of bolts passed through the upper edges drawn closer together, of a pair of top gusset plates and through the bent lower edges of two pairs of base half-gusset plates.
  • the modular supporting structure consists of a frame having the shape of an isosceles triangle, formed by a tubular base bar (1) and by two slanted tubular bars (2) with holes (1a) and (2a) at their ends.
  • the two slanted bars (2) are connected by means of a joint sleeve (3), made of a "U" box metal element positioned upside dawn, into whose opposite sides the ends of the converging bars (2) are fitted; the converging bars (2) are fixed to the top sleeve (3) by means of bolts, which are not illustrated in the enclosed drawings, and which pass through holes (3a) made for this purpose on the sleeve (3) and through the holes (2a) of the bars (2), where an internal tubular spacer (2b) is welded as illustrated in section A-A of fig. 1.
  • connection between the slanted bars and the horizontal base bar (1) is by means of two half-sleeves (4) each consisting of a metal box element having the same shape, but turned upside dawn with respect to that of the sleeve (3), having half the length of the latter.
  • each bar (2) is fitted into the opposite sides of the box shaped element (4) where it is fixed firmly by means of bolts which pass through a hole (4a) made on the half-sleeves (4) and through the bushing (2b), welded in the bar (2) at the height of the above end holes (2a).
  • connection between the bar (1) and the two side half-sleeves (4) is by means of a shelf (4b) welded on each half-sleeve (4) and ending with a transverse tubular spacer (4c) which perfectly fits into the bar (1) to allow the passage of the bolt which is fitted into the holes (1a) of the bar (1) so as to fix the latter to each half-sleeve (4).
  • these joint elements consist of pairs of gusset plates having suitable shape and sizes, in which the ends of the bars are bolted.
  • the pair of top gusset plates (30) in which the slanted bars (2) converge is formed by two identical, adjacent metal plates, each of which has two holes (30a) through which two bolts - not illustrated in the drawing - pass and fix the two slanted bars (2) inside the pair of gusset plates (30) respectively.
  • top gusset plates are characterized in that they have a double bend of 90° along the upper edges of each plate between which there is a space less than the existing space between the lower edges of these plates in which the ends of the slanted bars (2) are fitted and bolted.
  • Each base element joining the slanted bars (2) and the horizontal bar (1) consists of a pair of half-gusset plates (40) composed of two identical adjacent metal plates, whose shape and sizes are half that of the plates forming the pair of top gusset plates (30).
  • the distance between the two plates forming the pair of base half-gusset plates (40) is such that the edges drawn closer together, of the pair of top gusset plates (30) can fit perfectly into the lower bent edges of said pair of base half-gusset plates (40) where these edges drawn closer together can be fixed firmly by means of a bolt passing through holes (40c) and (30c) on the edges drawn closer together of the base half-gusset plates (40) and on the lower bent edges of the top gusset plates (30) respectively.
  • top sleeve is a ridge sleeve, i.e. a part of the module with which the trellis structure ends at the top, it has two side shelves (3b) terminating with a transverse spacer (3c) for connecting the horizontal bars (10) which join the top vertices of the adjacent modules with which the trellis structure ends at the top, as shown in fig 8.
  • top gusset plate is a ridge gusset plate, it has two holes (30b) for the bolts connecting the horizontal bars (10) which join the top vertices of the adjacent modules with which the trellis structure ends at the top; in this case there is no double 90° bend of the upper edges of the gusset plates.
