Definitions

• the invention relates, according to its most general aspect, to insulating panels with a composite structure, commonly used for the construction of walls, flooring, doors, roofs and the like, in civil, industrial or other kinds of buildings.
• the structure of these panels is often referred to as "sandwich" structure because it comprises at least one layer of insulating material, arranged between two outer walls at sight; the insulating material is generally a polyurethane foam or the like (but may also be rock wool or other insulating material), while the outer walls are in most cases made of sheet metal.
• the flexural rigidity of the panels improves when the height of its ribs is increased, the other conditions such as the thickness of the panel and of the metal sheets, the materials used, etc., obviously remaining unchanged; there are, however, drawbacks which prevent this height from being increased beyond certain limits.
• the technical problem underlying the present invention is therefore that of providing a panel with improved rigidity obtained by increasing the height of its ribs, without however encountering the drawbacks referred to above in connection with transportation.
• the idea for solving this problem consists in providing panel reinforcing sections, to be applied onto the ribs at the time of installation of the panel: these sections increase the height of the ribs and therefore the flexural rigidity of the panel, without negatively affecting the transportation costs since they are light and are mounted on the panel only for installation thereof.
• the reinforcing sections are fixed to the ribs by means of mating shapes which prevent them from sliding in the longitudinal and transverse directions; furthermore, the sections preferably have dimensions such that they may be stored, for example, in the empty spaces present between the stacked panels during transportation.
• FIG. 1 is a perspective view of an insulating panel on which a reinforcing section according to the invention is applied;
• - Fig. 2 is a cross-section through the above panel and section;
• FIG. 3 shows a cross-sectional view of two panels like the one above, in the stacked condition
• reference 1 denotes a composite insulating panel fixed to a beam 2 of a general support structure, such as, for example, the flooring of an industrial warehouse or a garret.
• Panel 1 (only a portion thereof is shown in the drawings) comprises an upper face 4 made of sheet metal, profiled with projecting ribs 5 of trapezoidal shape onto which screws 6 for fixing the panel to the beam 2 are applied.
• the screws pass through, from above, the insulating layer 7 of expanded polyurethane, mineral wool or the like, and the lower sheet-metal face 8 of the panel, so as to engage in the underlying beam 2 and thus ensure the required fixing.
• the sides of the trapezoidal ribs 5 of the panel are provided with impressions 10 obtained by means of pressing or other sheet metal processing operation, intended to engage with similar impressions 1 1 fonned on a reinforcing section 12.
• the latter a part thereof has been cut away in the drawings in order to reveal the underlying panel, is a metal section with an open cross-section which therefore has a certain degree of elasticity, so that it can be snap-engaged onto the respective rib 5 of the panel.
• the reinforcing section 12 does not operate like an ordinary covering element (of the type also called “junction cover” by persons skilled in the art) used to prevent the infiltration of rain water between the panels, but instead it co-operates with the underlying rib owing to the fact that it is locked with respect thereto in the longitudinal and transverse direction, thereby increasing the moment of inertia of the overall cross- section and hence the flexural rigidity of the panel.
• an ordinary covering element of the type also called "junction cover” by persons skilled in the art
• cross-section of the reinforcing sections may have a shape different from that shown in the drawings.
• Figures 4 and 6 show an embodiment where the width of the frets is much greater than that of the previous example.
• impressions 10 and 1 1 are only one of the possible solutions for fixing the sections to the panels; it may, however, be replaced by alternative solutions wherein the same result is obtained with other form-fitting arrangements, or using fixing means such as glue, adhesive tape or also welds.
• the reinforcing section 12 has free edges 15 which are folded and which engage in a respective groove 17, formed longitudinally in the side of the ribs 5 of panel 1.
• the groove is advantageously fonned with undercuts so that any flexural deformations of the panel are also transmitted to the reinforcing section, thereby obtaining the same effects explained above as regards the overall flexural rigidity.
• the folded edges 15 of the section 12 may slide longitudinally along the grooves 17 like along guides, they must be fixed in some way.
• the reinforcing sections be applied also in other zones of the panels, further to on the ribs; for example they may be applied along the junctions between the panels or in intermediate locations between the ribs.
• the effect of increasing the rigidity of the panel could also be obtained by applying sections according to the invention, between one rib and another; in this case the sections act as additional ribs with respect to those already present on the panels and do not have the (sole) function of increasing the dimensions thereof.
• suitable fixing means such as impressions, grooves, adhesives or any of the means mentioned above, in these intennediate zones where the sections are to be mounted.
