Definitions

  • the present invention relates to a connecting element for panels for the formation of coverings and the related roofing system (or covering), i.e. the assembly comprising the panels that are connected by the interposition of at least one connecting element.
  • the present invention relates to a connecting element for transparent panels for forming coverings suitable to let the light to pass through the same (such as skylight), for example in buildings for industrial use, such as warehouses, storehouses and the like.
  • the invention relates also to the relative connection way and in particular to a roofing system comprising at least two panels that are connected through the interposition of at least one connecting element according to the invention.
  • Transparent panels comprise a layer made of light material, such as for example polycarbonate, or polyester, plexiglas or other plastic materials, and in particular polymers.
  • transparent panels can be made of thermo-plastic material, for example by extrusion.
  • Transparent panels can be either of compact type or of honeycomb type.
  • Transparent panels are constrained to panels, preferably made of metal material, forming the covering.
  • transparent panels are constrained laterally to covering panels, preferably to panels made of metal.
  • the reinforcing net is constrained in contact with the surface of the layer made of transparent material, in particular to the lower surface of the layer made of transparent material, in contact with it.
  • This constraint can be made, for example, by means of an adhesive suitable for this purpose, such as for example a two-component adhesive.
  • an adhesive of fluid type is used.
  • Panels also have constraining ends, or protruding portions, forming constraining cavities suitable to accommodate corresponding constraining ends of the adjacent metal panels of the covering.
  • the constraining ends or protruding constraining portions have substantially a 'U' shape, and in particular an 'inverted U' shape and preferably comprise three inclined surfaces, according to the shape of a greek profile, widely used in the sector of roofing panels.
  • each panel is provided with two protruding constraining portions, preferably 'U'-shaped and extending at the two opposite sides of the panel.
  • protruding portions for example with an 'inverted U' shape, are used to constrain the panel to the covering, for example by means of screws or bolts.
  • a covering is provided with a series of metal panels alternated to skylights, i.e. areas of the covering designated to let the light pass through from the outside of the structure, the skylights being realised by means of the transparent panels described above.
  • An aspect of the present invention provides for a connecting element for transparent panels for forming covering, wherein the above mentioned connecting element comprises a main portion having at its ends two lateral portions, where each lateral portion connects the main portion to a respective supporting portion. Each supporting portion is spaced out (arranged at a distance) from the main portion and each supporting portion is configured for the connection to a transparent panel, and in particular for the connection to a constraining end or protruding constraining portion of a transparent panel.
  • An advantage of this embodiment is the fact that the connecting element has a complementary shape of the constraining ends or protruding constraining portions of the transparent panels, thus allowing an easy installation of one panel next to another, by means of the interposition of the connecting element.
  • the lateral portions connected to the supporting portions are arranged in correspondence of two ends, i.e. two sides of the main portion, and therefore they determine the formation of two protrusions, or raised portions (in relief) with respect to the main portion, substantially complementary to the constraining ends or protruding constraining portions of the transparent panel.
  • two transparent panels can be quickly and effectively constrained one next to another, by means of the interposition of the connecting element, each one in correspondence of a supporting portion of the connecting element.
  • the presence of lateral portions extending in correspondence of two ends, or sides, which are opposite sides and are preferably parallel to the main portion, from which in turn supporting portions extend spaced from the main portion determines the formation of two raised portions of the connecting element, having cavity underneath, each one is intended to cooperate with (in particular to be at least partially inserted into) the constraining ends or protruding constraining portions of a transparent panel.
  • each of the supporting portions extend towards the centreline of the main portion.

  • each supporting portion depart from the centreline of the main portion, i.e. it extend away from the centreline of the main portions.
  • the supporting portion extends from the lateral portion away from the centreline of the middle part, i.e. extending outwardly with respect to the main portion.

  • the width of the main portion smaller than the width of the metal panels commonly used on coverings, which, as it is known have an extension in width greater than one metre, allows the constraint of two transparent panels one next to the other and one close to another, without overlapping the respective constraining ends or protruding constraining portions, thus reducing the covered (non-transparent) area occupied by the connecting element.
  • the connecting element leads to the effective, safe and stable connection of two transparent panels, without their overlapping.
  • the connecting element has a predominant lengthwise extension.
  • the connecting element has an extension in length (Y) greater than the other two dimensions, and in particular greater than the width (X).
  • the length of the connecting element i.e. the extension in length of the ends, or opposed sides, of the main portion where the lateral portions extend from, is greater than the width of the main portion measured between these two ends, or opposed sides, of the main portion from which the lateral portions extend.
  • the width of the connecting element that is reduced in comparison with its extension in length, allows to keep close the supporting portions allowing the connection to two panels, and in general allows to keep close the supporting portions with respect to the main portion which are intended to cooperate with the constraining ends or constraining portions of the panel.
  • This configuration allows to give to the connecting element the necessary stiffness, while at the same time keeping its size limited when arranged between two panels which are connected through it.
  • each one of the two lateral portions is angled with respect to the main portion.
  • the lateral portion extends from the main portion forming an angle ( ⁇ ) with it. This angle allows to set the supporting portion, that is connected to the main portion through the lateral portion, at a distance (spaced out) from the main portion.
  • each one of the two lateral portions is connected to an end of the main portion forming an acute angle.
  • the lateral surface is extending from the end of the main portion forming an acute angle between them.
  • the angle is measured internally with respect to the two surfaces, i.e. the angle faces the centreline or the middle part of the main portion.
  • an acute angle allows the lateral surface extending from the main portion to project towards the centreline (middle part) of the main portion forming an inclined lateral surface cooperating in increasing the stability and the stiffness of the connecting element.
  • the presence of an acute angle provides that the lateral surface, as well as the supporting portion extending from it, do not extend sideways outside the size in width of the main portion.
  • each one of the two lateral portions is connected with an end of the main portion forming an obtuse angle.
  • the lateral surface and the supporting portion extending from it extend sideways outside the size in width of the main portion.

  • the protection element is provided with a main portion, that can comprise two surfaces 40b and 40c arranged at a small folding angle between them, and ending in correspondence of two ends of the main portion with two angled portions 40a and 40d.
  • the protection element 40 can be realized in metal plate, for example in aluminium plate.
  • a layer 41 of insulating material (for example a foamed polyurethane) can be arranged on the lower surface of the protection element which is intended to contact, in use, with the upper portion of the constraining portions 20' that is constrained to the connecting element 30, 30'.
  • This layer of insulating material allows to increase the tightness and consequently acts as a gasket against the passage of water, dust, impurities, etc. from outside.
  • this layer of insulating material 41 profitably allows the elimination, or at least the reduction, of any possible formation of water condensation.
  • Figure 6 is a section view of an alternative embodiment of the connecting element, shown with the numerical reference 30'.
  • the connecting element 30' of panels 15 comprises a main flat portion 30g having at its ends 31 two lateral portions 30a,30d angled (at an obtuse angle ⁇ ) with respect to the main portion 30g, where each one of the lateral portions 30a,30d is connected to a supporting portion 30b,30e which is spaced out from the main portion.
  • each of the supporting portions 30b,30e depart (extend away) from the centreline (A) of the main portion 30g.
  • the connecting element 30 is shaped in such a way that the supporting portions 30b,30e, extending from the respective lateral portions 30a, 30d, do not overlap, in general, with the main portion 30g, but are anyway on a different plane with respect to the main portion 30g.
  • this shape results in the presence of two cavities substantially arranged underneath each supporting portion 30b, 30e, which allow, like in the case of the connecting element 30 previously described, the housing of at least parts of connection means 60 of the panels 15 to the connecting element, as for example screws, etc.
  • each one of the two lateral portions 30a,30d is connected at obtuse angle to one end of the main portion 30g.
  • the connecting element 30 can be referred to a further embodiment of the connecting element shown in Figure 6 , and vice versa, with the exception of the different extension of the supporting portions 30b, 30e, that in one case extend towards the centreline of the main portion so as to result overlapped to it, and that in the second case they extend sideways as regards the main portion away from the centreline.
  • the connecting element 30, according to the present invention allows the connection of two panels in adjacent position, i.e. one next to the other one, by the interposition of the connecting element 30 between them, in a quick and simple, but also effective and safe way.
  • the roofing system comprises, as described above, at least two panels and a connecting element 30, 30' every two panels 15 that has to be connected, as for example shown in Figure 2 and in the detailed view of Figure 1 .
  • a roofing system (or set of panels for forming covering) comprises a plurality of panels where two adjacent panels 15 are constrained by means of a connecting element 30, 30'.
  • connection of the constraining ends 20' of the transparent panels 15, for example of a surface 20b of the constraining ends with a connecting element 30, and in particular with the respective supporting portions 30b, 30e, is carried out by connection means, preferably screws 60.
  • the second surface 20b allow the installation of connection means 60, and in particular of screws that, when in use, are let to pass through it, and through the supporting portion 30b, 30e of the connecting element, down until remaining at least partially housed in the cavity formed underneath the supporting portion which, as already said, is spaced out from the main portion 30g.
  • connection means 60 for example screws, will be installed at variable spacing according to constructive requirements.
  • the reinforcing layer, and in particular the net 25, is laid, as said before, in correspondence of the constraining ends or protruding constraining portions 20' of the panel and interposed between the panel and the connecting element.
  • the net 25 is arranged in a such way that the connection means 60 (for example screws) are inserted at least in one mesh of the net, as for example shown in the embodiment of Figure 1 .
  • connection means 60 for example screws
  • At least one mesh of the net 25 is positioned externally compared to the mesh where the connection means 60 are inserted.
  • the net extends also on the surface 20c of the protruding constraining portions 20' of the panel 15, and the meshes arranged in correspondence of this surface 20c remain outside the connection means 60.
  • the reinforcing layer 25, and in particular the net has an extension on the constraining ends or protruding constraining portions 20' of the panel, so as, after the installation of the connection means 60 (for example a screw), at least one wire 25a, and preferably at least two wires 25a of the net (as for example shown in the embodiment of Figure 1 ), extending preferably along the panel length, remain outside the connection means 60.
  • the connection means 60 for example a screw
  • the connecting element 30, 30' of panels 15, can have an extension along the length and therefore an extension along the ends 31, or sides of the main portion, so as to have a curvature instead of having a straight extension as shown for example in the embodiment of Figure 5 .
