Definitions

  • the present invention relates to an arched monolithic panel (or plate) structure, of the type constituted of two sheets from key-patterned or micro-staved metal plate with the interposition from thermally insulating material and provided with means of high sound-absorption and sound-insulation acoustic capacity, such as to render the panel particularly useful for the roofing of industrial and civil buildings and the like.
  • the arched or curved monolithic panels for the roofing of buildings are constituted of an external sheet from key-patterned plate from steel, aluminum or other alloys and an internal sheet from metallic plate, also key-patterned or micro-staved, between which a layer from thermally insulating material, usually expanded or rigid polyurethane foam, is interposed.
  • the assembly of the acoustic or curved panels involves for the operator special care and special equipment in the adjustment of the position of each panel relatively to the position of the adjoining panel, in order to prevent the creation, between the flat edges of each couple of adjoining panels, of an irregular fissure throughout the length of the joint lines; said fissure involves the drawback, after the fastening of the panels, of causing the passage of air not only between the planes in touch with each other, but also between the inclined walls of the key-patterns overlapping each other of each couple of adjoining panels.
  • US-A-3,290,845 discloses an insulated roof panel system. Each panel is of rectangular configuration and is curved or bent in an arcuated form. The panel has an outer skin and an inner skin. Between said skins a central insulating core of foamed plastic is provided, which is bonded to the outer and inner skins. During joining of the panels fissures are formed which become air tight by means of using gaskets between the joining inner skins and foam cores.
  • An object of the invention is to realize a structure of arched monolithic panel of the type constituted of two key-patterned and/or micro-staved metal sheets, which panel incorporates a thermally insulating material, said structure being so designed and structured as to impart the panel a high sound-absorption and sound-insulation acoustic capacity.
  • a further object of the invention is to realize an arched monolithic panel of the above specified type incorporating means for stiffening the ends of said panel such as to ensure a correct and suitable fastening of the panel to the bearing structure, as well as an increase in the bearing capacity of said panel.
  • a not least object is to realize an arched and key-patterned monolithic panel of easy realization and assembly and high reliability in the time.
  • an arched monolithic panel suitable for the realization of building roofing of the type constituted by an external or upper sheet from key-patterned metal plate, an internal or lower sheet from micro-staved metal plate substantially shaped as a small tank or tray lower tray-shaped sheet, and a thermally insulating material interposed between said plate sheets
  • said panel structure comprising, according to the present invention, air-tight closing means to prevent the passage of air through fissures created by the coupling by the overlapping of each panel of the roofing structure on the adjoining one, said closing means being constituted by at least a gasket from elastically yielding material inserted between the end of the flat edge protruding from the lower sheet of each panel and the flat edge of the lower sheet of the adjoining panel intended for the ledge-overlapping on said end of the flat edge of the adjoining panel, so as to seal the fissure created after the stable coupling between said two adjoining panels, preventing in this way the passage of air also between the
  • said air-tight means preventing the passage of air through said fissure are constituted by the combination of said gasket from yielding material, inserted between said flat edges ledge-overlapped of each couple of adjoining panels, and of a like gasket from yielding material interposed between the intrados of the high part of the key-pattern of the upper sheet in a panel and the extrados of the high part of the upper key-pattern of the adjoining panel after the coupling by overlapping of the two panels.
  • said sound-absorbing and sound-insulating material is positioned above or close to the lower sheet or tray of each panel, in the form of pads or spaced-band gaskets or also in the form of a continuous gasket; in this way, also the bottom of said tray may be realized as a separate-band micro-holed bottom, said bands corresponding to the widths of the overlying pads.
  • the structure of arched panel realized according to the present invention utilizes an arched monolithic panel of a known type, for instance the one shown in Figure 1, wherein there is indicated by 1 the key-patterned external or upper support panel, substantially a sheet from key-patterned plate, by 2 there is indicated the internal or lower plate sheet either micro-staved or key-patterned according to a key- pattern different from that of the external or upper sheet 1, while by 3 there is indicated a thermally insulating material of either the expanded or the rigid type, such as expanded polyurethane or mineral wool; said insulating material 3 is substantially contained in a tray obtained by shaping the internal or lower metal sheet 2.
  • each arched panel in order to allow the joining by overlapping of the lower sheet of a panel on the lower sheet of the adjoining panel, each arched panel, indicated as a whole by P in the various figures, has a flat edge 2a that protrudes from the lower sheet 2 parallel to the key-patterned lines of the external or upper supporting sheet 1 (see p. 1).
  • the flat edge 2a protruding from the lower sheet 2 has usually a length 2b (Fig. 1) bent up until it tilts on plane 2a.
  • the structure of monolithic panel that constitutes the object of a first embodiment of the present invention utilizes a panel P of a known type and realizes the coupling with an adjoining like panel P1 (Figs. 2 and 3) according to the known technique, namely by overlapping, on the upper side, of the arched side key-patterns 1a and 1b of the two adjoining panels and, on the lower side, by ledge-bearing of the flat edge 2c of the adjoining panel P1 on the protruding flat edge 2a of panel P (Figs. 2-3).
  • the ledge-bearing of said two flat edges 2a-2c creates, as is known, between the two edges a fissure which is the more accentuated the more irregular are the parallelism between the faces of the flat edges and the accuracy employed during the assembly of the two adjoining panels.
  • the present invention provides the interposition between said flat edges 2a-2c of the two coupled panels of a compressible air-tight gasket 4 (Fig. 3) from open-cell expanded material or the like; said gasket may be stably anchored, during the production of the panel, to the internal face of either flat edge of the panels to be coupled; besides, instead of a gasket from expanded material, the air-tightness through said fissure may be realized by means of a silicon band or the like.
  • a like gasket 5 may be inserted also between the two high key-patterns 1a and 1b, overlapping each other.
  • the structure of monolithic panel is realized as shown in Figures 4 and 5, i.e., by interposing between the lower sheet 2 having the shape of a tray with alternated-band micro-holes in the lower part, as indicated by 2d in Figure 4, or also for its whole development as indicated by 2e in Figure 4, and the thermally insulated material 3, an acoustic barrier, substantially a gasket 6 from open-cell expanded material or also a rigid material, such as mineral wool, rock wool or the like, suitable to impart the panel advantageous sound-absorbing and sound-insulating characteristics.
  • a stiffening element 7 (Fig. 6) is inserted which is substantially a metal sheet, suitably sized and so bent as to have a cross-section shaped as a capital "C", and of a length allowing to position said stiffening element at the opposite ends of the panel, transversally to the development of the key-patterned lines 1.
  • said stiffening element 7 increases the mechanical resistance and the bearing capacity of the panel, and prevents screws 8 fastening said panel to the underlying bearing structure 9 (Figs. 7 and 8) from causing tears of the lower sheet 2 during the permanence of said panel and an undesired compression of thermal 3 and acoustic 6 insulating materials.
  • Figure 7 shows the anchoring system of a panel 1 provided with a stiffening element 7 onto a fixed support 9 where the fastening screw 8 is inserted in the panel from the innermost side of the key-pattern 1; in both realizations there are in practice obtained the same results of stable anchoring, without strains of the gaskets and/or pads interposed between the upper key-patterned sheet and the lower one or tray, independently on whether the latter is solid or micro-holed.
