Definitions

  • the present invention relates to a cover element prefabricated consisting of a quadrilateral panel having on two of its opposite sides a rim extending substantially over the entire length of these sides, these two edges rising on the same face of the panel and comprising means making it possible to connect the edge of a first panel with the adjacent edge of a second adjoining panel oriented in the same sense and located in the same plane as said first panel.
  • One of the essential aims of the present invention is to propose a cover element which can be mass-produced industrially and precisely in the workshop at a low cost compared to the elements of prefabricated roofing known and whose implementation does not generally require no know-how and specific equipment, which in common cases allows installation by a single non-specialist person.
  • BE-A-528371 discloses cover elements obtained from from a rectangular metal sheet. These elements are provided on their raised edges of a clamp and an edge border allowing the engagement of bins juxtaposed, folding forming joint cover. There is therefore no need to resort crimping of juxtaposed elements, but the problems due to assembly by strength are not resolved.
  • FR-A-929893 describes metal cover sheets, to rolled side edges fitting into the corresponding edge of a neighboring sheet.
  • a stapling device is provided, consisting of a transverse strip welded to the upper bet of each sheet and intended to receive a fold of the sheet immediately superior. These sheets are rectangular. They don't have upward side edges forming said standing seals which provide sealing in heavy rain.
  • the cover element is essentially consisting of a panel having substantially the appearance of an isosceles trapezium, the two non-parallel sides have said edges, the length of one of bases of the trapezoid being substantially equal to that of the other base increased by twice the thickness of the wall of said edges, in such a way as to allow to engage the ends of the flanges on the side of the shortest base with the ends at the side of the longest base of another extending element in the extension of said determined element and parallel to said flanges.
  • the panel has on its aforementioned face, at near its longest base, a retaining member allowing to immobilize, one with respect to the other, in a determined position, two successive elements engaged in the extension of one another according to the longitudinal direction of their edges.
  • the aforementioned retainer has the form of a clamp oriented towards the base the shorter of the element on which it is provided, this base having an edge which is at least partially folded in the shape of a clamp towards the opposite side to that on which is arranged the retaining member, so as to allow the retaining member of a specific element to cooperate with the above folded edge of another element engaged in the extension of this determined element in a direction parallel to the longitudinal direction of their edges.
  • Figure 1 is a perspective view of an element of cover according to this particular embodiment.
  • Figure 2 is a section along line II-II of Figure 1.
  • Figure 3 is a section along line III-III of Figure 1.
  • Figure 4 is a perspective view of a part of the roof formed by cover elements according to this embodiment with seals aligned.
  • Figure 5 is a view similar to that of Figure 4 with staggered joints.
  • Figure 6 is a section along line VI-VI with broken Figure 4.
  • Figure 7 is a partial section along line VII-VII of the figure 4.
  • Figures 8 and 9 are schematic plan representations of two possible assemblies.
  • the particular embodiment of the cover element prefabricated consists essentially of a panel 1 having the appearance of an isosceles trapezium whose two non-parallel sides 2 and 3 have two flanges 4 and 5 standing on the same face of the panel 1.
  • the length of the large base 6 of the trapezoid is substantially equal to that of the small base 7 increased by twice the thickness of the wall of the ledges 4 and 5.
  • the edges 4 and 5 have such a geometry that it is possible to engage their ends 8 on the side of the small base 7 of an element of cover determined with the opposite ends 9 located at the side of the large base 6 of another element extending in the extension of the element cited in first place.
  • the panel 1 has on its upper face, near its large base 6, a retaining member 10 for immobilizing, one relative to the other, in the position of laying on a roof, two cover elements successive engaged in the extension of each other according to the direction longitudinal of their edges 4 and 5.
  • the retaining member 10 has the form of a strip extending over the entire width of the upper face of the panel 1 parallel to the large base 6 and has a somewhat Z-shaped cross section, so as to form two wings 10a and 10b which are interconnected by a zone intermediate 10c now these two wings 10a and 10b at a distance one of the other somewhat greater than that of the thickness of the panel 1.
  • the wing 10a which is oriented towards the large base 6, is fixed to the panel 1 by means of suitable fasteners 11 such as clinching or rivets, so that a slot 12 is formed between the panel 1 and the wing 10b.
  • the small base 7 has a folded edge 13 in the form of a clip of the side of the rear face of the panel 1, while the large base 6 has an edge 14 which is folded towards the upper or front face of the panel 1, the function of which is essentially allow the panel to be fixed by the use of tabs adapted and to prevent the penetration of water by capillarity, as it will still be set out below.
  • the free edge 4 ′ of one of the edges 4 is folded towards the other edge 5, while the free edge 5 'of the latter is folded towards the outside of the element blanket.
  • the free edge 4 ′ has a section transverse in the shape of a clamp, while the free edge of the other flange 5 has the shape of a hem or bead 5 'delimiting a longitudinal cylindrical hollow 15 and having a slot 16 extending along the external lateral side of the rim 5.
  • the cross section of the portion of the bead 5 'nearby of the large base 6 as well as that of the bead 5 'and of the slot 16 near the small base 7 are such that the portion of the bead 5 'near the large base 6 can fit into the part of it near the small base 7.
  • the height of the rim 5, near the base most short 7 is substantially equal to that of the rim at the level of the retaining member 10, reduced by the height of said retaining member 10. This height corresponds to minus twice the thickness of panel 1 plus once the thickness of the slat forming the retaining member 10.
  • the height of the rim 4 near the base most short 7 is such as to be able to engage below the corresponding part of this ledge located near the longest base 6. This operation is facilitated by a bevel 22 of the edge 4 'of the rim 4 near the longest base 6.
  • the part of the 5 'bead close to the large base, has a neck-shaped stop 17 making it possible to limit the length of engagement of the portion of the bead 5 ′, located near the small base 7 of a second panel, around the part of the bead 5 'located near the large base 6 of a first panel.
  • a clearance of a few millimeters is preferably provided between two successive cover elements 1 along their longitudinal direction of so as to allow interception of the effects of thermal expansion of said elements 1 in this direction.
  • the axis of the cylindrical hollow 15 of the bead 5 ' extends more or less in the plane of the rim 5 presenting said bead 5 ', this especially for aesthetic reasons.
  • edges 4 and 5 varies from gradually and continuously between the two bases 6 and 7 of panel 1.
  • the covering element can in principle be produced in any weather-resistant material and suitable for use on the roof, a preference is given to a prefabricated cover element consisting of a sheet of zinc, copper, stainless steel or galvanized steel.
  • the particular geometry of the following covering element the invention greatly facilitates installation on a roof to be covered.
  • a second element 1b is placed above of element 1a, said element forming an angle of approximately 45 degrees with the element la so that their corresponding 5 'beads are located in the extension of one another and that the edge 4 of the second element 1b is located above the first element 1a.
  • the second element 1b is then subjected to a displacement downwards, as indicated by the arrow 18, so as to engage its bead 5 'the along that of the element la until the stop on the stop device 17 disposed on said bead, device consisting of a constriction.
  • the assembly of the two hems constituting an axis of rotation it is then possible to rotate the second element 1b so as to engage its edge 4 'under that of element 1a, by effect of clipping. This operation is facilitated by the bevel cut 22 of the edge 4 'of element 1a at its longest base 6.
  • the panel 1 of element 2a is brought into the same plane as that of panel 1 of element 1a, then in its exact position by sliding it on the rim 4 of the element 1a, that is to say with the corresponding bases 6 and 7 in the extension one others in the case of installation with aligned joints.
  • the offset between the bases corresponds to a half length of an element coverage standard.
  • element 2b For the installation of element 2b, we proceed first as with element 2a in the way just described then as with element 1b on element 1a to allow engagement of the folded edge 13 of element 2b in the slot 12 of the retaining member 10 of the element 2a.
  • the folded edge 4 'in the form of a clamp of the rim 4 forms with this last an angle less than 90 ° so as to prevent the ingress of water by capillarity in the lateral joint between two adjacent rows of elements of blanket. It is the same for the folded edge 14 at the large base 6 which prevents therefore the water rising by capillarity between the superimposed parts of two successive elements can pass over the large base 6.
  • the minimum slope of these elements is preferably higher or equal to 15%.
  • These elements can also be used as cladding, that is to say in a substantially vertical position, for example in coating of facade of a building.
  • the free edges of the ledges 4 and 5 may have other shapes.
