Definitions

  • the present invention relates to a number of significant improvement in prefabricated reinforced concrete self-bearing roofings used for industrial buildings.
  • Prefabricated reinforced concrete self-bearing roofing elements are known, for istance, from the German patent DE-A 1 919 200.
  • Said patent describes reinforced concrete elements having generally "V"-shaped cross section, disposed side by side and linked at the top by joint elements, for example transparent material made, to build skylights.
  • the general object of the invention is to embody a roofing element for buildings that has the dependability, practicality and efficiency of prepared (damp-proofed) prefabricated corrugated roofing, generally made of asbestos lumber or iron sheeting, and the appearance of a plane structure.
  • the object of the invention is to embody a roofing element that is able to fulfil the following functions:
  • a further object of the invention is to embody a roofing element that is not only able to accept overlaid prepared corrugated sheets, but also to provide:
  • the said objects are attained by embodying a prefabricated self-bearing reinforced concrete roofing element of the type having a generally "V"-shaped cross section, wherein the sides of the "V” of the said element extend from a longitudinal rainwater gutter characterized in that spaced longitudinal ribs are provided on the sides of the "V” onto which are fixed roofing sheets which converge on the said gutter.
  • the sheets are forming a hollow space that serves both to contain insulant material and for the passage of air for ventilating the structure, and wherein the said roofing element terminates at its opposed ends in respective headpieces each comprising a shoe for a support girder, which shoe also features a series of projecting ridges for bearing a shoe of an identical overlaid roofing element.
  • the roofing element in question is indicated overall by 9 and consists of a prefabricated self-bearing reinforced concrete article of substantially "V"-shaped cross section with sides 10 of the "V” that typically terminate in headpieces 11 and outerly present two pairs of spaced longitudinal ribs 12, the more inward of which demarcate a central longitudinal rainwater gutter 19.
  • the headpieces 11 are provided with a shoe 13 for a support girder 14 carried by pillars 15.
  • the shoe 13 also features two pairs of projecting ridges 16, 18, terminal and central respectively, which serve as bearing members for the shoe 13 when a number of roofing elements are stacked as shown in Figure 4 and, in addition, exactly space the stacked elements so as to prevent the weight from coming to bear on the roofing. Particulars used for raising the roofing element are buried in the central projecting ridges 18.
  • FIG. 1 of the drawings clearly shows, to the longitudinal ribs 12 there are secured corrugated roofing sheets 20, for example made of asbestos lumber, which, with the element 9, form a hollow space for air circulation and for containment of a layer 21 of insulant material, for example rockwool ( Figures 5-8).
  • corrugated roofing sheets 20 for example made of asbestos lumber, which, with the element 9, form a hollow space for air circulation and for containment of a layer 21 of insulant material, for example rockwool ( Figures 5-8).
  • Figures 10, 11 and 12 show the use of the roofing elements disposed spaced apart while Figure 13 shows them in side-by-side arrangement.
  • Figure 11 shows the provision for lean-to copings 23, while a continuous skylight 24 is shown in Figure 12.
  • the roofing elements according to the invention as a result of the absence of ribs on their underside, in no way impede light from entering.
  • the structures described above, employing the tiles of the invention, have the great advantage that they permit a summertime ventilation of the roofing, which is conceived and realized so as to set-up air circulation that prevents the irradiation of the damp-proofed roof struck by sunlight from accumulating heat in the underlying structure, which latter can then re-distribute the air into the workplace.
  • the air inlet and outlet point (shown by the arrows in Figures 10-13) must not allow small birds to pass through and possibly make their nests. This is assured by means of a special element 25 made of plu- ri-perforated plastics material ( Figure 9) which adapts perfectly to the profile of the asbestos lumber sheets and allows air to pass through: the element 25 has a continuous flat base 26 which is bonded to an underlying listel or gasket, and a wavy upper profile which harmonizes with the section of the asbestos lumber sheeting.
