Definitions

  • the present invention relates to an H-beam, that is, to a beam comprising a central part or core, and two side-flanges, and which can be used for constructions, or restorations of buildings, etc.
  • H-beams form solid, that is non-hollow monolithic elements, fabricated according to standardized sizes, and must be necessarily cut in certain cases, in order to adapt to the required span.
  • the beam also has a disadvantageous ratio weight/load bearing capacity. This is seen as a drawback by the consumer, and moreover it complicates transport.
  • the laying of the beam is particularly troublesome, because it is necessary to first introduce one end of the beam in a wall hole, and thereafter to move the whole beam body in the opposite direction, in order to introduce the other end of the beam inside the hole previously realized in the opposite wall.
  • the conventional beam is moreover very bulky in certain specific applications in which civil buildings are to be restored, and it would be advisable to have available a kind of modular beam, and even a lighter beam, that is a beam with an advantageous ratio of weight to load bearing capacity.
  • US 3,224,154 discloses a multi-piece readily assembled building beam, which has a generally rectangular cross-section with opposite side walls and a bottom and top wall.
  • US 3,328,931 discloses an improved beam comprising a pair of channels preferably made of sheet metal and bolted or welded together back to back in a relation in which the channels are slightly offset longitudinally for lapping connection with another beam. Even if the object is to make lighter and less expensive beams, which may be readily assembled, the channels do not have folded flanges as in the present application. Therefore, even if some of the objects are similar, the present application discloses a beam which structurally differs from the beam of US 3,328,931.
  • BE 374 538 discloses a beam comprising two identical U-shaped strips of sheet metal, connected in face contact by their backs, in order to form a core or web of double thickness and lateral fins, and comprising further U-shaped covering strips which enclose said fins and clamp the latter so as to cover them and maintain all components in an assembled state. This document does not disclose a way to connect the components in a staggered way.
  • An object of the present invention is to realize an H-beam of a modular (sectional) kind, so as to eliminate size drawbacks.
  • a further object is to optimize the ratio of weight to load bearing capacity.
  • a third object of the present invention is to include the possibility to adapt the beam features, in the regions (flanges) which are more subject to bending stress, to particular situations or applications, in other words to the load, so as to increase the versatility of the beam.
  • a fourth object of the present invention is to include the possibility of adapting the beam to a definite span, by assembling the same with the use of said modules.
  • the module 1 comprises two identical half-structurals, or half-parts of structural steel, denoted by 2a, 2b.
  • half-structurals 2a, 2b are formed e.g. by a thin-walled steel sheet of 2 mm of thickness.
  • Fig. 2 illustrates the configuration of the half-structural 2b.
  • the half-structurals 2a, 2b are preferably obtained by means of a forming machine, even if the use of a moulding process should not be excluded.
  • the forming machine performs the folding operations in order to obtain the half-flanges 4a, 4b - and 4c, 4d respectively -, of the half-structurals 2b and 2a. It can be noticed that the half-flanges 4a, 4b, 4c and 4d are actually "hollow", that is, they enclose a cavity 5 between two parts of the respective half-flange 4a, 4b, 4c and 4d, connected to each other by a bent portion 6.
  • plates 7, 7' are respectively inserted inside the cavities 5.
  • Plate 7 is introduced in the cavities 5 associated with the half-flanges 4a, 4c, whereas plate 7' is inserted inside the gaps 5 of the half-flanges 4b and 4d.
  • the "filling" plates 7, 7' of the half-flanges are provided with a plurality of holes 8, 8' respectively, and the same is true for both half-structurals, which have holes 9 on their central part (or core) 10, and holes 9'on the flanges, these holes being provided on both parts of each half-flange 4a-4d, in aligned relationship, and also aligned to the holes 8, 8' of the plates 7, 7' (after assembling, as shown in Fig. 1).
  • the holes are used for the connection of all components 2a, 2b, 7, 7', which is obtained by riveting, and in the central part, they serve - in conjunction with the beads 3,3'- in order to avoid instability effects, like an enlargement of the central part and the concomitant detachment of the two parts 10, 10 which form the central part (core) of the beam.
  • Rivets like those used in the aeronautical field are preferably introduced in the holes 8, 8', 9, 9', but the use of bolts or the like is obviously not excluded.
  • the particular construction process allows to distribute the material in a more rational way, thereby reducing the amount of material employed.
  • the lower flange formed by the half-flanges 4b,4d which corresponds to the region more subject to bending stresses, may be strengthened by inserting a plate 7' having an increased thickness and/or an increased width.
  • modules with "symmetric” or “asymmetric” structurals having flanges with different thicknesses and/or widths, to take into account - for the latter case - the greater bending stress of the lower flange 4b, 4d.
  • Holes may be provided between the beads 3, 3', 3", etc. realized on the cores 10 of the half-structurals, said holes being adequately reinforced at their edges and being used as lightening holes or for providing a passage for a system (e.g. lighting system, water supply, etc.).
  • a system e.g. lighting system, water supply, etc.
  • the H-beam according to the present invention may be realized by moulding its components.
  • a forming machine which, starting from a strip, is able to shape it (formation of the beads and the holes for the passage of the systems), and to cut it to the desired size.
  • the advantage with respect to a foundry process is due to the fact that it is not necessary to modify the whole production plant in order to vary - for instance - the thicknesses of the half-flanges 4b, 4d if it is desired to insert a plate 7' with a larger thickness.
  • the structure of the H-beam according to the invention is also advantageous because it allows a greater "flexibility" of the production process as compared to the conventional processes.
