Definitions

  • the present invention relates to a panel structure, particularly for roofs of buildings.
  • the panel structure of the present invention is specifically designed to form covering layers for flat roofs.
  • Flat roofs are characterised by a minimal slope, sufficient to ensure the runoff of water to the drainpipes. According to UNI standards, flat roofs are defined as those with a slope of less than 5%.
  • insulating metallic panels that generally consist of a layer of insulating material coupled with a metal sheet.
  • This known type of insulating metal panels generally has a coupling side along which the sheet is folded so that it can be coupled to the sheet of the adjacent panel.
  • this known type of panels has an interlocking system that makes the covering subject to infiltrations if the slope is not substantial.
  • DE 20 30 482 A1 discloses a composite building panel comprised of a plank element provided with a main body portion which terminates at each end thereof in upstanding flanged portions one of which includes a terminal bead and the other of which includes a deformable sleeve that can be folded tightly about the bead on a similarly configured panel when a pair of such similarly configured panels are disposed in adjoining relationship.
  • a backer member is secured to the underside of the main body portion of the panel, the marginal side edges of such backer member terminating adjacent the normal planes of the flange portions and a joint sealing strip of sponge-like material is affixed to one of the marginal edges of the backer member and closely adjacent the side of the panel that is to constitute the warm face of the panel.
  • DE 102 17 190 A1 discloses a profiled plate for the covering of roofs of buildings having a profile of a first elbow seam on a hood-type profiled section and inside this section forming in the longitudinal direction of the seam a first location, and on one side of a reference plane extending perpendicularly to the plane of the plate and for locating against a first inclined face on the section of the second elbow seam gripped by the first.
  • the first elbow seam on a side of the reference plane facing away from the first locating face forms a second inclined face for a second location formed on the part of the second elbow seam gripped by the first.
  • JP S52 28314 U discloses a panel structure including an insulating body and a sheet with coupling edges.
  • US 4 476 659 A discloses establishing an insulation cavity by connecting rail tracks to roofing panels, slidably engaging adjustable suspension clips within the tracks, and connecting ceiling panels to the depending end of the suspension clips.
  • the suspension clips are slidable within the track connections to allow the relative displacement between the roof and the depending ceiling. This freedom allows flexibility in the alignment of the ceiling panels in relation to the roofing panels and thereby simplifies installation procedures.
  • WO 2017/214642 A1 discloses a roofing sheet having a mounting component interconnected with a covering component, the mounting component including a profile which includes a longitudinally extending base shaped and configured to be fastened to a purlin and a first side wall extending from one side of the base.
  • the mounting component includes a retaining means in the form of a first extension extending from the first side wall and a second side wall extending from an opposing side of the base and a receiving means in the form of a first clip formation which extends from the second side wall.
  • the covering component includes a profile which includes a longitudinally extending valley defined by a base having a first side wall and second side wall extending from opposing sides of the base and a second retaining means in the form of a second extension extending from the first side wall of the covering component for receiving and retaining the first extension of the mounting component therein.
  • the covering component further includes a connecting member extending from the second side wall shaped and configured to receive a mounting component and second extension therein in an operative connected condition with an adjacent roofing sheet.
  • the aim of the present invention is to provide an insulating panel structure particularly suitable for creating covering layers for flat roofs.
  • one object of the present invention is to provide a structure comprising a system for coupling the panels to one another that will ensure a perfect seal from atmospheric elements.
  • Another object of the present invention is to provide a panel structure that is easy to install.
  • a further object of the present invention is to provide a structure that, for its peculiar structural characteristics, is capable of ensuring ample guarantees of reliability and safety when used.
  • the panel structure particularly for roofing of buildings, according to this invention, generally indicated by the reference number 1, comprises a sheet 2 associated with an insulating body 3 and provided, on two opposite sides, with a first coupling edge 4 and a second coupling edge 5.
  • the coupling edges 4 and 5 are elastically deformable so that, by moving one structure towards another, the edges 4 and 5 mutually engage, defining an interlocking area in which the coupling edges 4 and 5 form one or more inner chambers.
  • the first coupling edge 4 comprises a first lower upright 41, substantially vertical, which extends in an inner wing 42 and a first upper upright 43 connected to a first flat portion 44.
  • the flat portion 44 end in a first turn-under 45.
  • the second coupling edge 5 comprises a second lower vertical upright 51 which extends in a second lower bend 52.
  • the second lower bend 52 then extends into a second upper upright 53, which ends in a second upper bend 54 having a recess 55.
  • the second upper bend 54 extends in a C-shaped portion, indicated with the reference number 57, which ends in an end wing 56.
  • the coupling edges 4 and 5 When engaged, the coupling edges 4 and 5 form a plurality of inner chambers: a first chamber 61 formed between the first upper upright 43 and the first flat portion 44, of the first edge 4, with the second upper bend 54 and the C-shaped portion 57, of the second edge 5.
  • the first chamber 61 is partially divided into two semi-chambers by the presence of the end wing 56 of the second upper bend 54.
  • a second chamber 62 and a third chamber 63 are formed between the second upper upright 53, the second lower bend 52 and the second upper bend 54, of the second edge 5, and the first lower upright 41 and the inner wing 42 of the first edge 4.
  • the panel structure 1 also comprises brackets for fastening to the purlin, which are indicated with the reference number 7, adapted to fasten the panels to the support structure of the covering layer.
  • Each purlin fastening bracket 7 comprises a base 71 connected to a purlin bracket upright 72 that ends in a hook element 73.
  • the base 71 has holes for engagement of screws 74 adapted to engage the purlin or another support structure of the covering layer.
  • the purlin bracket upright 72 varies in length according to the thickness of the panel.
  • the structure 1 also comprises wind-barrier locking clips consisting of two metal profiles, indicated with the reference numbers 8 and 9, adapted to be fastened to the edges 3 and 4, after having carried out the coupling thereof.
  • the profiles 8 and 9 are fastened together with screws, for example with countersunk heads 10 or hexagonal heads 11, as can be seen in figures 4 and 5 , respectively.
  • the structure 1 also has fastening brackets for accessories and other auxiliary structures typically present on roofing, such as lifelines, solar panels, etc.
  • Figure 8 illustrates a universal bracket, indicated with the reference number 12, consisting of a pair of profiles, indicated with the reference numbers 121 and 122, respectively, each of which has a lower portion that envelops the interlocking area of the panels and an upper portion adapted to be secured by means of screws 123.
  • the upper portions of the profiles extend sufficiently and comprise holes 124 for the fastening of various types of components.
  • Figure 9 illustrates a plastic bracket, indicated with the reference number 13, consisting of a pair of profiles indicated with the reference numbers 131 and 132, respectively, each of which has a lower portion that envelops the interlocking area of the panels and an upper portion adapted to be secured by means of screws 133.
  • the upper portion of at least one of the two profiles, profile 131 in figure 9 comprises a shaped portion 134 adapted to engage various types of components.
  • the structure of the covering panel of the present invention is installed, on an essentially flat roof, by fastening a first panel to the support structure, by means of the brackets fastened to the purlin 7.
  • a second panel 1 is caused to slide towards the first one and pushed until the first edge 4 of the second panel engages the second edge 5 of the first panel.
  • the second panel is coupled to the first one, it is then necessary to secure the second panel to the support structure of the covering layer, by means of the purlin fastening brackets 7, and then couple a third panel to the second one, and so on.
  • the coupled edges 4 and 5 can be secured together by means of the wind-barrier clips 8 and 9 and/or the auxiliary fastening brackets 12 and 13.
  • Figures 10 and 11 illustrate a fastening system of the structure by means of a special bracket 107, which is fastened laterally to the purlin, according to a further aspect of the invention.
  • the structure 1 does not have, on the lower side, the "step" shape to leave room for screws and bracket, but rather has a special bracket 107 adapted to be fastened laterally to the purlin.
  • Each special bracket 107 comprises a base 171 connected to a bracket upright 172 that ends in a hook element 173.
  • the base 171 has holes for engagement of at least one screw 174 adapted to laterally engage the purlin or another support structure of the covering layer.
  • the base 171 extends at a right angle and vertically relative to the bracket upright 172.
  • the special bracket 107 is not as easy to fasten as the bracket 7 of the previous example, which is preferable and mostly used in industrial sheds, however, on a production level, it is possible to quickly and easily vary the structure 1 by including the bracket 7 or the bracket 107.
  • a panel structure has been provided, specifically designed for covering essentially flat roofs, i.e. having a slope of 1% or less.
  • the coupling system makes it possible to easily install large and heavy panels since, thanks to the elastic deformability of the edges, it is not necessary to tilt one of the panels to couple it to another and it is sufficient to slide the panel to be coupled against a panel already fastened to the structure.
  • the coupling system ensures an excellent seal against atmospheric agents, even the most intense ones, thanks to the labyrinth-like conformation created by the inner chambers inside the interlocking area, which prevents water from leaking in, and thanks to the wind-barrier clips that firmly secure the edges to each other.
  • Another advantage of the structure is due to the accessory fastening brackets that exploit the interlocking area of the edges to secure them and provide a support to auxiliary components to be installed on the roof.
