Definitions

  • the present invention regards a prefabricated insulating panel for roofing of buildings, comprising:
  • the structure of the panels of the type referred to made up of the aforesaid layer of insulating material fixedly set between the two mutually parallel rigid or semirigid sheets, is substantially monolithic, and this guarantees good characteristics of water-tightness to any infiltration, of thermal insulation, and of mechanical resistance. For said reason, the panels of the type referred to above are widely used for the construction of roofs of buildings.
  • the panels are generally produced in some versions, which are differentiated from one another as regards thickness of the upper sheet, of the lower sheet, and of the layer of insulating mass.
  • the length of the panels can be varied, in the production stage, according to the final installation.
  • each pitch is formed by a respective plurality of juxtaposed panels.
  • the sealed junction between the two opposite inclined pitches, each formed by a respective plurality of panels, is obtained by installation of an additional ridge element, which defines the ridge line of the roof.
  • Rectilinear panels of this type require relatively complex or extensive substructures, designed to support the panels that provide each pitch in an inclined position.
  • prefabricated insulating panels designed for covering individual bays of buildings, where by "bay” is understood the span or space comprised between two load-bearing rests or elements of the structure of a building, such as for example prefabricated parallel beams made of reinforced concrete of an industrial building.
  • these panels In order to guarantee off-flow of water, these panels have a curved shape so as to present a ridge region. Also the monolithic structure of these panels comprises an upper sheet and a lower sheet, curved according to one and the same radius and set parallel to one another, provided between which is the layer of insulating material.
  • the two parallel longitudinal ends of the panels can be supported by means of the two load-bearing rests or elements defining the span of the bay, without the need for complex or extensive supporting substructures.
  • the aforesaid load-bearing rests or elements are set at an inter-axis that is generally comprised between 5 and 7 m, and the curved panels are mounted perpendicular to them.
  • the free span to be covered is generally comprised approximately between 2 m and 4 m.
  • the length of the curved panels - understood as distance between the two longitudinal ends - is generally comprised approximately between 2.5 m and 5 m, whilst the width (or pitch) - understood as distance between the two side edges of the panel - is generally approximately 1 m.
  • these curved panels are modular, with the possibility of coupling together the front and back of different panels, in the direction of length of the bay.
  • additional units such as, for example, photovoltaic modules.
  • the installation of an additional unit on the curved surface of the panel is evidently inconvenient for the persons responsible for installation, on account of the aforesaid steep slope.
  • panels with wide radius of curvature have comparatively reduced structural characteristics: the installation of an additional module evidently reduces the possibility of the panel supporting further loads thereon, such as for example snow, or the weight of persons responsible for carrying out repair/maintenance of the module.
  • an additional unit having a planar or rectilinear configuration such as for example a photovoltaic module, imposes prior mounting on the curved panel of a relatively complex structure for supporting and fixing the unit.
  • DE102008031453 A1 upon which the preamble of claim 1 is based, discloses a prefabricated roof module having a set of sandwich roof elements with an insulation between an outer upper metal sheet and an inner lower metal sheet. Both the metal sheets form side-inclinedly bent regions and horizontally bent edge regions.
  • FR 2376931 A1 discloses a multilayer load bearing element suitable for roofing, comprising a punched metal sheet, an intermediate layer comprising an expanded mineral material and a lower layer made of reinforced glass fibers.
  • GB 1282144 A discloses a roof covering unit for securing to a roof structure comprising a decorative skin of material shaped to simulate a plurality of roof tiles, at least two spaced walls extending from the skin to give the roof covering unit an overall thickness that is in excess of the overall thickness of the skin, a further skin spaced from the decorative skin and interconnecting the spaced walls, and counter-battens disposed and retained between the skins for receiving fixing means extending from the roof structure.
  • the object of the present invention is basically to overcome one or more of the aforesaid drawbacks of curved panels of the type referred to in a simple and inexpensive way.
  • the object of the present invention is solved by the technical features of claim 1. Said object is achieved, according to the invention, by a prefabricated insulating panel having the characteristics specified in the annexed claims, which form an integral part of the technical teaching provided herein in relation to the invention.
  • Figure 1 represents a prefabricated insulating panel provided according to one embodiment of the invention for the roofing of individual bays of buildings.
  • the panel designated as a whole by 1, has a monolithic structure that comprises a lower sheet 2, preferably but not necessarily made of metal material, and an upper sheet 3 made of metal material.
  • the layer 4 can be provided with a foamed material, such as, for example, a self-extinguishing polyurethane resin or a polyisocyanurate foam or a foam containing flame-retardants.
  • the very gluing capacity of the foamed material used can be advantageously exploited for fixing the aforesaid components 2-4 of the panel 1 to one another in order to obtain the aforesaid monolithic structure and thus prevent the need for welded or mechanical connections.
  • two longitudinal ends may be identified, designated by S, and two side edges, designated by F and R, hereinafter defined as front and back, respectively, only by way of reference of the modalities of coupling between a number of panels.
  • the panel 1 has a length L, understood as distance between the ends S, and a width or pitch W, understood as distance between the front F and the back R.
  • At least the upper sheet 3, and preferably also the lower sheet 2 are fretted or corrugated; i.e., they have parallel ribbings, which extend substantially throughout the length of the sheets themselves, between the ends S.
  • the sheets 2 and 3 can be obtained via rolling from sheet metal, for example stainless-steel or galvanized sheet, or sheet of aluminium or copper, possibly painted or subjected to other surface treatment.
  • parallel ribbings that are the same as one another, some of which are designated by 5 in Figure 3 .
  • longitudinal ribbings projecting upwards, in such a way that the top surface of the panel 1 presents a recurrent pattern.
  • the upper sheet 3 envisages a plurality of deep (high) ribbings, some of which are designated by 6a, 6b, 6c, and a plurality of shallow (low) ribbings, some of which are designated by 7.
  • the lower sheet 2 can present a plurality of ribbings 5 substantially parallel to one another and with respect to the front F and to the back R of the panel.
  • the front F and the back R are shaped so as to enable watertight juxtaposition of a number of similar panels 1.
  • the front F (or the back R) of one panel 1 can be coupled via overlapping to the back R (or to the front F) of another panel 1.
  • the upper sheet 3 in a region corresponding to the front F of the panel 1, is shaped to provide part of a deep ribbing 6a, which is external to the space of containment of the insulating mass 4 (it should be noted that said external ribbing 6a could be formed also by shaping appropriately the lower sheet 2, in the case where said sheet 2 is intended to be used for "closing" laterally the space for containing the insulating mass 4).
  • the upper sheet 3 is shaped for defining a deep ribbing 6b, designed for shape fit with the ribbing 6a of another panel 1.
  • Figure 3 is a schematic illustration of the step of superposition of the ribbing 6a of one panel 1 on the ribbing 6b of a different panel 1.
  • Figures 2 and 4 are, respectively, a schematic cross section and a perspective view of a number of panels 1 coupled in the way described. Final fixing between the panels 1 juxtaposed in the aforesaid way can be obtained with modalities and means in themselves known in the sector, for example, screws and U-bolts.
  • the coupling of the panels 1 via overlapping must be deemed preferred, but is not indispensable.
  • the front F and back R of two panels can be just set alongside and coupled in a water-tight way by means of a butt strap, according to a technique in itself known in the sector.
  • the shape fit between the front F and the back R of two different panels 1 also includes a longitudinal appendage 8 (comprising, for example, a shaped portion of the rear edge of the lower sheet 2) of a panel 1, designed to fit into a longitudinal recess 9 defined in the face of the insulating mass 4 corresponding to the front F of another panel 1.
  • the panel 1 has a ridge region that extends between the front F and the back R.
  • the upper sheet 3 defines, in opposite parts with respect to the ridge region, two opposite rectilinear pitches of the panel 1.
  • the sheet 3 is shaped so as to define two inclined surfaces, designated by 10, which form the two aforesaid pitches, with the ridge region of the panel 1, designated by 11, that is defined in the intermediate area or area of transition between the two inclined surfaces 10.
  • the panel 1 according to the invention has a configuration substantially with rectilinear double pitch, and said shape, in addition to guaranteeing the necessary running off of water, enables the problems typical of curved panels of the type described previously to be overcome, in particular so that it will be possible to walk on them and/or in order to guarantee a sturdiness and resistance thereof to loads and/or facilitate mounting thereon of additional units, such as rectilinear photovoltaic modules.
  • additional units such as rectilinear photovoltaic modules.
  • the slope of at least one of the inclined surfaces 10, preferably of each inclined surface 10, is less than 25%. In the embodiment currently deemed preferential, said slope is comprised between approximately 3% and approximately 8%, preferably approximately 5-6%. Said reduced slope constitutes a considerable advantage in that it means that the panel 1 can be walked on by a person carrying out maintenance operations without any risk of him slipping.
  • the configuration of the sheet 3 with opposed inclined surfaces 10 facilitates, when necessary, also installation of additional elements on the panels 1, such as, for example, the photovoltaic modules.
  • the two inclined surfaces or pitches 10 can have one and the same slope and length, with respect to the ridge of the panel 1, as in the case of Figure 1 . In other embodiments, however (see, for example, Figure 9 ), there may be envisaged different slopes and/or lengths for the two rectilinear pitches 10.
  • the two sheets 2 and 3 are not parallel to one another; namely, the general development of the sheet 2 in a longitudinal direction (i.e., between the two ends S) is different from the general development of the sheet 3 in a longitudinal direction.
  • the lower sheet 2 has a longitudinal general development that is substantially rectilinear, i.e., it lies substantially in a plane.
  • the upper sheet 3 has, instead, a longitudinal general development that defines the two inclined surfaces 10 having opposite slopes.
  • the panel 1 has, in cross section, a shape that is at least approximately triangular, approximately the shape of an isosceles triangle (in actual fact, in the example shown, the cross section is substantially shaped like an irregular pentagon, but as may be seen, the geometrical shape recalled visually is at least approximately triangular).
  • the thickness of the layer of insulating material 4 is variable starting from each end S up to the area corresponding to the ridge region 11.
  • the thickness increases from a minimum, in an area corresponding to the ends S, to a maximum, in an area corresponding to the ridge region 11.
  • the overall structure of the panel 1 is very sturdy and distinguished by an increased load-bearing capacity.
  • the panel 1 according to the invention consequently has also an insulating mass of increased thickness.
  • the configuration of the base constituted by the sheet 2 presents the further advantage - in the condition where the panels are installed - of reducing the internal space of the building that must be heated in the cold seasons as compared to a roofing obtained via the curved panels described previously. It should be noted that the panels 1 can be exploited to provide directly also a substantially plane false ceiling, in which case the respective lower sheets 2 will be preferably painted or subjected to a surface treatment.
  • the same advantages highlighted above can be achieved also with a sheet 2 that is not exactly rectilinear.
  • the sheet 2 could even be undulated (albeit arranged according to a respective substantially rectilinear general plane), or again it could be a slightly arched sheet 2, with concavity facing upwards or downwards.
  • the two inclined surfaces 10 defined by the upper sheet 3 intersect at the ridge region 11 to define a ridge line 11a of the panel 1 ( Figure 1 ).
  • the shaping of the sheet 3, after the latter has possibly undergone rolling is relatively simple in so far as it requires a simple operation of folding of the sheet itself.
  • the angle formed between the two inclined surfaces 10 can be comprised between 169° and 177°, preferably between approximately 172° and approximately 174°.
  • the ridge region defined by the upper sheet 3 may not be “sharp”: in other words, the sheet 3 can be bent during the production stage to define - for example between the two inclined surfaces 10 - an intermediate area or area of transition that is horizontal or has some other form.
  • the distances D and E indicated correspond evidently to different thicknesses of the insulating mass 4 that fills the gap between the two sheets 2 and 3.
  • the length L of the panel 1 is between 2 m and 5 m, preferably between approximately 2.5 m and approximately 4 m.
  • the preferred pitch or width W of the panel 1 is not greater than 1.5 m; preferably, the useful width W is approximately 1 m.
  • the prefabricated insulating panels 1 according to the invention can be used for top roofing of individual bays, i.e., of the span or space comprised between two parallel load-bearing rests or elements of a building, with each panel 1 arranged perpendicular to the aforesaid rests, i.e., with the ends S of the panels 1 that are supported by them.
  • Figure 7 is a partial and schematic illustration, merely by way of example, of an application of the above sort.
  • Figure 7 shows the structure with bays of a generic building, which is assumed as being a shed for industrial use, said structure being provided via elements made of pre-compressed reinforced concrete.
  • the width or span of each bay is basically represented by the distance between the two parallel load-bearing elements designated by 20, which here are assumed as being beams made of reinforced concrete, supported via columnar elements 21, which are also made of concrete.
  • the prefabricated insulating panels 1 according to the invention are used for roofing the individual bays.
  • a number of panels 1 are coupled one after another - in the way described previously with reference to Figures 2-4 - in the direction of length of the bays themselves (said direction is perpendicular to the plane of the sheet of Figure 7 ), i.e., according to the direction of width W of the panels.
  • Anchorage of the panels 1 with respect to the beams 20 can be provided with methodologies and means in themselves known in the sector.
  • the roofing of each bay can be completed at the two ends S of the panels via suitable accessories according to the known art, not represented, such as, for example, flashing, gutters, drip edges, or edge trims, designed to enable collection and/or running-off of water and/or prevent the risk of infiltration of water into the building.
  • suitable accessories such as, for example, flashing, gutters, drip edges, or edge trims, designed to enable collection and/or running-off of water and/or prevent the risk of infiltration of water into the building.
  • FIGS 8, 9 and 10 illustrate some possible variant embodiments of the panel 1 according to the invention.
  • the panel 1 of Figure 8 presents a construction and use that are generally similar to the ones described previously with reference to the Figures 1-7 .
  • the upper sheet 3 is shaped so as to present, in the regions of the ends, stretches S' that are at an angle with respect to the corresponding inclined surfaces 10, are preferably generally plane or rectilinear, and are substantially parallel to the lower sheet 2.
  • the longitudinal-end regions of the panel are defined by parallel stretches of the sheets 2 and 3, but in other embodiment not illustrated herein the stretches S' can project in a cantilever way towards the outside, beyond the insulating mass 4 and/or the lower sheet.
  • the stretches S' may indicatively have a length of approximately 10 cm.
  • the provision of these rectilinear stretches S' in the two longitudinal-end areas is particularly advantageous during production of the panel in so far as it facilitates the operations of cutting of the sheet 3.
  • FIG. 9 The embodiment of Figure 9 is conceptually similar to those already described above, with the difference that in this case the two inclined surfaces 10 have different lengths and slopes. Panels having a configuration of this type can be used, for example, for providing roofing of a "shed" type. It may be noted that, also in the case of the panel 1 of Figure 9 , the presence of the stretches S' of the sheet 3 substantially parallel to the sheet 2 are to be deemed preferred, but not strictly indispensable.
  • the panel described is a roofing panel that can be numbered amongst monolithic prefabricated modular components.
  • the structure of the panel described is simple and guarantees the necessary modularity. Said structure moreover enables panels of dimensions also different from one another to be obtained, without this causing substantial variations in the production cycle.
  • the panels according to the invention enable considerable advantages to be obtained as compared to the known curved panels envisaged for similar applications.
  • Figure 10 regards a possible alternative embodiment of a panel according to the invention.
  • This embodiment differs from the previous ones substantially in that the longitudinal general development of the sheet 2 is similar to that of the sheet 3.
  • the sheet 2 is shaped so as to define two opposed inclined surfaces, here designated by 10'.
  • both of the sheets 2 and 3 of a panel of this sort have respective end stretches S', for the reasons already explained previously.
  • the two longitudinal-end regions lie in one and the same general plane, and this facilitates positioning of the panels on plane surfaces, such as for example the top surfaces of the corresponding load-bearing elements 20, as may be clearly seen in Figure 11 .
  • the angle formed between the two inclined surfaces 10' of the lower sheet 2 is different from the angle formed between the two inclined surfaces 10 of the upper sheet 3, so as to have in any case a thickness of the insulating material 4 that is variable between the ends S and the ridge region 11.
  • the panel 1 of the embodiment of Figures 10 and 11 renders walking on the panel safe, thanks to the modest slope of the inclined surfaces 10, and enormously facilitates installation of additional units, such as plane photovoltaic modules, as explained previously.
  • the upper sheet 3 of the panel 1 has shaped ribbings for resting and/or supporting opposite edges of an auxiliary panel unit, i.e., a unit having a configuration structurally or functionally similar to those described in the Italian patent No. 1.346.172 and/or in the Italian patent application No. TO2007A000633 , filed in the name of the present applicant.
  • an auxiliary panel unit i.e., a unit having a configuration structurally or functionally similar to those described in the Italian patent No. 1.346.172 and/or in the Italian patent application No. TO2007A000633 , filed in the name of the present applicant.
  • the aforesaid ribbings can be exploited for providing in themselves a supporting structure for an auxiliary unit, such as, for example, a rectilinear or plane photovoltaic panel.
  • these supporting ribbings extend in height above the plane of lie of the auxiliary unit, as described in TO2007A000633 , and are shaped so as to define each both a resting surface for the corresponding edge of the auxiliary unit and a surface of delimitation of a seat for the auxiliary unit, orthogonal to the aforesaid resting surface.
  • At least one channel for the passage of cables and/or pipes, for example cables for electrical connection of a photovoltaic unit.
  • the thermally insulating mass 4 can be made of any material suitable for the purpose, even other than a layer of foamed material, for example a layer of mineral fibre, or else it could comprise a number of layers, such as a foamed layer and a fibre layer.
  • the lower sheet 2 can be made of a rigid or semirigid non-metal material, for example asphaltic felt paper, glass-reinforced resin, or glass fibre.
  • the panels forming the subject of the invention are used for providing a roofing for a building of an industrial type with a number of bays. It is, however, evident that the panels according to the invention can be used also for providing roofs of other types of buildings with a single bay, such as for example roofs for garages, whether prefabricated or not, even with metal load-bearing structure.
