Definitions

  • the subject of the present invention is a method of constructing roofs in round tiles on self-supporting bins and a roof obtained.
  • the technical field of the invention is that of the construction of Tiled roofs channel or round tiles of cylindro-conical form.
  • FR 2 541 709 describes a method which makes it possible to provide new roof tiles made of round tiles, which make it possible the architectural aspect of the traditional roof, a process in which the round tiles are laid on a sub-roof that presents a good water and air tightness, which is easy to install and reduces the cost of roof.
  • This process involves the use of metal bins self-supporting, usually galvanized or oven-lacquered bins, which are used to build roofs of industrial buildings or side siding.
  • Self-supporting tanks made of laminated sheet metal or laminated resins have, thanks to their ribbed niche shape, very good resistance to bending, so that the failures that support them can be spaced.
  • This crenellated profile makes it possible to stiffen the tray and thus to works of reduced thicknesses and therefore lighter bins compared to a tray in profile with fluted corrugations, that is to say of round shape.
  • roofs of this type is very fast and does not require not a highly qualified workforce and this method of constructing roofing reduces the time and cost of building roofs in round tiles.
  • This process makes it possible to obtain a good mechanical connection between the tiles and self-supporting bins thanks to the presence of a formed reinforcement expanded metal band or wire mesh extending over any the length of the bins, which is attached to the anchor bolts of these on the These self-supporting bins can be made by hand cold rolling or bending of galvanized or kiln-lacquered steel sheet, standard width.
  • roofs of this type compared to tiled roofs rounds laid on corrugated fiber-cement plates, lies in the fact they allow to build roofs with lower slopes thanks to better sealing and thanks to the shape of the recessed grooves which allow a better flow of water.
  • a disadvantage is that tiles, whose round concave shape is not supported by the crenellations whose vertices are flat, must be supported by a interlayer material or device adherent on the tray and supporting the roof tiles.
  • the implementation of a lattice reinforcement which allows the adherence of the mortar on the self-supporting tray, represents a laying work additional weight and additional weight.
  • the mortar also has some disadvantage. Firstly, its weight is relatively high, a material with a density of more than 1000 kg / m 3 and, in practice for roofing, a surface density greater than 25 kg / m 2 . In addition, the mortar reacts differently from the constituent material of the tile as a function of the ambient temperature, generating different dimensional variations that can induce delamination of the tile, or even the breaking of tiles. Finally, the mortar does not provide regular continuous support on the underside of the tile because, when the mortar dries, it retracts in a non-homogeneous manner, which generates mini zones of vacuum under the tile which constitute as many points of the tile. sound insulation failure but also risk of delamination or fragility of the tile.
  • the object of the present invention is therefore to provide a method of realization of round tile roofs placed on a profiled steel tank in niche that does not have the disadvantages of the process of the prior art, in particular described in FR 2 541 709, in particular with means for supporting and adhering tiles on said bins self-supporting that do not have the disadvantages of implementation a metal lattice reinforcement combined with a mortar for adhesion and supporting the tiles on said bin.
  • the present invention provides a method for producing of a roof tile channel in which said tiles are placed on supports including self-supporting ribbed bins, crenellated, by arranging the son of said sloping tiles on the tops of said crenellations, and said overlapping tiles in such a way that the lower end of each tile covers the upper end of the tile located immediately lower in the slope, said tiles presenting, all, a concavity directed downwards.
  • the present invention offers several advantages.
  • the means of connection between the tiles and the steel tanks constitutes a continuous bearing surface on the underside of the tile and this, as well in the case of old-fashioned tiles of shapes non-repetitive irregularities for which we will then advantageously a so-called expanded polyurethane foam material in situ, which in the case of industrial tiles of identical regular shapes for which can then be used as well preformed wedges that shims of expanded polyurethane foam in situ.
  • said wedges preforms are made of polystyrene, polyurethane or a mixture of cement and light particles such as expanded glass beads, expanded clay beads or mineral or vegetable fibers.
  • said material, consisting of said polyurethane foam or said preformed wedges has a density of 35 to 55 kg / m 3 .
  • said material consisting of said expanded polyurethane foam or said shims preforms occupies the volume formed between said tiles and said vertices said slots so that said vertices of said slots are located substantially at a height corresponding substantially to half of the depth of said tiles.
  • the inventors have, in fact, discovered that the quantity of said material and in particular expanded polyurethane foam thus implemented is sufficient to confer both support and support Reliable mechanical tiles on the self-supporting tray ..
  • the weight of said material depending on the nature of the material may be from 10 g / m 2 to 10 kg / m 2 , more particularly from 5 g / m 2 to 1000 g / m 2 .
  • the weight will generally be 5 to 10 kg / m 2
  • this weight will generally be 100 to 1000 g / m 2
  • the weight of the material will be more particularly from 20 to 500 g / m 2 .
  • a laying of about 10 tiles per m 2 is carried out , said tiles overlapping in each line over a length of 5 to 10 cm.
  • said vertices of said crenellations have two longitudinal grooves, each of which is said to be grooves being disposed along the side edges of said slots and thus delimiting the width of the area initially covered by the moss expanded polyurethane at the time of its removal on said vertices of said slots in the form of polyurethane foam cords.
  • said tiles are glued to each other at their ends at said area of cover without fixing hook.
  • said tiles are shaped tiles uniformly identical and said material is constituted by said wedges preformed.
  • said tiles are tiles of irregular shape and not identical and said material consists of said expanded polyurethane foam.
  • said vertices of said crenellations have a width of 110 to 115 mm, said slots having a height of about 50 mm and the side of said slots trapezoidal angles diverging upwards at an angle between 0 and 15 °.
  • These self-supporting tanks are made of sheet metal 0.5 to 1 mm thick and have a weight of the order of 4 to 10 kg / m 2 which is a relatively low weight compared to that of other known sub-roofs, this which allows to lighten the frame.
  • the present invention also relates to a roof of the type comprising round tiles, obtained by a method according to the invention, characterized in that it comprises, interposed between said tiles and said tray, a said material as defined above.
  • the present invention aims to facilitate the construction of roofs of individual houses but it is not limited to this application and roofing according to the present invention can be used for cover other buildings, including collective dwellings or industrial premises.
  • the roof according to the present invention results from the laying of tiles 1 frustoconical on a preformed steel tray 2, a material 3, 4 ensuring the maintaining tile 1 on tray 2.
  • Figure 1 shows a first embodiment

  • the sheet thus formed advantageously has a variable length, maximum 1200 mm, a working width of 660 mm and a height of crenel of 50 mm.
  • a vertex 21 forms a convex trapezium the length of which Small upper base 212 is about 113 mm.
  • Slot 22, less broad, forms a concave trapezoid whose length of the small base lower 221 is about 85 mm.
  • bins are supported by unrepresented structural elements which may be metal or wood frames or precast concrete. They are for example fixed on non-represented battens by bolts or lag bolts, or threaded rods, or any other equivalent fastener, which pass through fastening advantageously drilled through the small base 212 of the vertices 21, in contact with the tiles, the small base 221 concave slots 22 being in contact with the battens.
  • each tank advantageously has each of its ends a portion of vertex 21, made so that the portion 21 of a second tank that covers the summit portion 21 of a first tank next to it, has a small base 212 full and part side 211 extending over at least one third of the length of the side 211 complete the top portion 21 of the first bin. This last also a small base portion 212 which extends under at least the half the length of the small base 212 complete the second bin.
