Definitions

  • the invention deals with a spatial structural prefabricated element made by means of folding and/or molding, conceived to make a rigid body, like a sandwich, with a high resistance to compression, bending and sagging in such a way that, having an internal structure such as spatial structures, nevertheless, it has the peculiarity that the inner polygons delimited by the bars of the spatial structures themselves are embodied, and are flat polygonal surfaces.
  • This determines a prefabricated material that can be used in any industrial field, in engineering, building and agriculture to obtain forging, partition walls, enclosures, panels of any kind to build walls, insulation, floating bodies and in general terms, any kind of application field for many different uses.
  • the prefabricated element can be obtained easily, either folding a sheet of the adequate material or by means of molding always obtaining a prefabricated material with a light weight and a high resistance thus providing more advantages and better mechanical and economic performance than the elements and/or products known up to now.
  • a spatial structure is a setting of resistant elements whose behavior analysis can be determined by the traditional system of independent planes such as in the case of frameworks, roof trusses, tiles, arches, lattices, etc...
  • the calculation complexity of a spatial structure resides in the determination of the axial stresses of each of the elements (bars) of which the set, taken as a whole consists.
  • these sets are composed by a studding or a triangle shaped mesh of equal bars joined at common corners called spatial knots.
  • the invention is related to the so called spatial structures but not in its design and/or its formal execution aspect.
  • the main difference is that whereas spatial structures are assembled like a meccano by means of joints between bars and knots, the prefabricated spatial element, object of the invention is obtained from filling the flat surfaces defined by the above bars (which are transformed into the sides or edges) and the knots (which are transformed in the polyhedral vertices of the resulting pyramids).
  • the differences are obvious.
  • the prefabricated element of the invention is the result of the shaping by means of folding, molding or extruding of the geometrical surfaces defined by the bars and the nuts of the spatial structures.
  • the prefabricated element can be complemented with supplementary fittings, zig-zag shaped, joined to the inclined edges from vertex to vertex in such a way that, as they coincide with the orthographic crossings of the edges formed in each of the horizontal surfaces, they could easily be electrowelded to any net superimposed on the above horizontal surfaces.
  • the technical problem to be solved is the prefabrication of a new building material, light, in a higher or lower degree according to its components and to the resistance necessary in each case, a material with which we can obtain better advantages and performances than with the materials known up to now.
  • the prefabricated element obtained in each case either by folding or by molding or extrusion will have a texture or inner folding and a flat or spherical finishing in one or in both external surfaces independently from the shape of the side edges.
  • the desired element can be used plates or sheets of natural or artificial elements provided they can be folded by molds and/or molded.
  • the four inner sides of the above tetrahedrons and their common assembly point "0" are precisely the sides and the vertex of the respective inverted pyramid (1') of figure 3, whose inclined edges coincide exactly with de edges, equally inclined of the pyramids converging at point "0".
  • the sides of the basis of such inverted pyramid (1') are in turn the upper edges of each of the inserted tetrahedrons (2), with sides equal to the distance between each of two consecutive vertexes, within the set of the four pyramids considered (1) shown in figure 4.
  • the aim is to obtain a sheet formed by polyhedral figures in which the sides of the relevant pyramids are embodied. That is, the aim is to obtain laminar bodies of any adequate material but this body should be formed by a series of pyramid figures obtained by means of any polygon configuration; or similarly, to obtain a spatial structure in which the faces defined by the bars of the above spatial structure are embodied such as it happens with the circle which is the embodiment of the inner space of the circunference.
  • the material execution of the laminar body which will constitute the spatial structural prefabricated material, according to the object of the invention, can be made by means of folding or molding.
  • the lower mold (the tongue) will be composed by a series of pyramids (1) arranged as shown in figure 4, whereas the upper mold (groove) will be composed by as many void pyramids (fig. 1) as necessary, and arranged as the above to make the upper and the lower fit.
  • the external faces are closed by means of an adequate sheet or mesh with determines the plane shape of the former. This is achieved by means of adherence or welding of the edges of the basis of the pyramids to the above sheet or mesh thus obtaining the sandwich element already mentioned.
  • the mold should be identical and they should have as many tetrahedrons as necessary to be fitted between every two consecutive pyramids.
  • the edges of the above should be made according to the kinds of joint that should be obtained between the different panels.
  • figure 5 shows an straight external edge (3); figure 6 shows a projective external edge (3'); figure 7 shows a French roof edge (3'').
  • a specific element shape can be obtained according to the polygon combination chosen.
  • the left area A shows a plan view with some pyramids missing; the right area B corresponds to the depiction of the upper edges; the lower area C shows the lower edges whereas the lower area D, shows the inclined edges.
  • the lower figure (elevational view) corresponding to figure 7, shows the French roof edge (3'') and the plates (4) which could close horizontally the upper and lower side of the prefabricated element obtained.
  • the spatial structural prefabricated element obtained either by folding or molding, according to the invention and generally referred to as #5 in addition to the insulation panels (6) of figure 5, can be stiffened by means of bars either in zig-zag or broken which would follow the relevant edges.
