Definitions

  • the present invention relates to an assembly of battens allowing their rapid storage and installation, at the desired spacing, on rafters forming a receiving surface for the subsequent fixing of covering elements and consisting of a series of battens, parallel and regularly spaced, fixed on a continuous sheet formed of a flexible material, the battens being, moreover, connected to each other by parallel, thin, flexible, resistant and substantially inextensible strips which are arranged transversely to the axis of the battens and fixed to them at their intersection.
  • batten assemblies are known where the batts are connected together by parallel, thin, flexible, resistant and substantially inextensible strips which extend transversely to the axis of the battens and are fixed to these at their intersection, so that each strip is disposed between the sheet and the strips and isolated by the sheet from the atmosphere prevailing on the other side of the sheet.
  • batten assemblies have been found to be suitable for rapid installation on a roof but relatively expensive to manufacture because it is necessary to provide a double stapling: - to fix the resistant bands and - for the flexible continuous sheet of relatively weak plastic and intended to be torn off after the installation of the battens on rafters and just before the installation of the cover to allow normal ventilation of the roof.
  • batten assemblies Another function envisaged for such batten assemblies, namely the provisional removal of water from the building and the recovery of leaks under the roof, could not be achieved using batten assemblies of this type.
  • the present invention aims to achieve this additional function while reducing the manufacturing costs of such assemblies.
  • the subject of the present invention is an assembly of battens in which the continuous sheet has good resistance to tearing and tearing and is inserted between the battens and the resistant parallel strips whose spacing corresponds substantially to that of the rafters of the surface. receiving, in which the continuous sheet is held in place by the stapling of said strips on the battens at their intersection with the latter, and in which the length of the flexible sheet between two contiguous parallel parallel strips is greater than the length of the battens separating these two contiguous bands, so as to form at least one channel between two rafters when the two contiguous bands are placed on two contiguous rafters.
  • the continuous flexible sheet comprises perforations arranged in zones distinct from that of the channel.
  • the continuous flexible sheet has perforations whose edges are raised in the direction of the battens.
  • the perforations can advantageously be replaced by microperforations originally produced in the flexible sheet and which, by a surface tension effect, prevent the flow of water while allowing the passage of ventilation air. of the roof.
  • the transverse thin parallel strips are stapled at their intersection with at least each of the end strips of the assembly using several staples. This increases the resistance to stapling of this first batten subjected to adjustment pulls during installation.
  • the continuous flexible sheet extends beyond all of the battens and the stapling of the parallel strips on the battens is carried out using staples with divergent ends or with a bevel bent towards the outside, so that the staple penetrates deeply into the batten in the direction of the length of the batten and parallel to the surface of the continuous flexible sheet, without protruding outside said batten, and achieves a local clamping of the flexible sheet continues with strong parallel strips.
  • the fixing on the roof rafters is carried out by nails simultaneously passing through the flexible sheet and the resistant strips.
  • the method according to the present invention for fixing a batten assembly as defined above on a receiving surface, preferably a roof is characterized in that after the laying of the batten assembly on the rafters correspondents of the reception surface, placed along a line of greatest slope of the roof by pressing resistant parallel strips on said elements, the continuous flexible sheet forms between two adjacent rafters a relatively deep central channel of water flow out of the roof which delimits a ventilation space of the roof and which is suitable for temporarily putting the building out of water and for recovering leaks in the under-roof.
  • the sheets of two assemblies are covered placed side by side on a roof, at the ends of the assembly in the direction of the roof slope and at the roof ridge at least before laying the cover by folding down and the lower part of the sheet is curved to bring towards the means of collecting the water collected on the flexible sheet.
  • the assembly of battens shown in Figure 1 consists of a series of battens 10 (noted here 10 a to 10 c ) usually made of rough sawn wood, in common dimensions (in particular between 15 x 36 mm and 50 x 50 mm) and if possible free of knots to facilitate stapling by force engagement, in dry or partially green wood, of U-shaped staples of a preferred type which will be described below.
  • the battens could be made of another material capable of being stapled, in particular plastic and / or elastomer.
  • the battens are arranged parallel and equidistant from each other at pitch L to be fixed on the rafters 11 of a roof and are stapled by means of staples 14 on one side of a continuous thin sheet 12 of a flexible resistant material and generally transparent, for example polyethylene or polyane.
  • the battens are further connected to each other by parallel strips 13, thin, flexible, resistant and substantially inextensible and equidistant from each other, extending transversely to the axis of the battens and fixed by the clips 14 to each of these by tightening on the strip 10 the sheet 12 which is also crossed by the staple 14.
  • the U-shaped staples 14 are preferably oriented with the U bar parallel to the axis of the battens to better support small misalignments of stapling.
  • the head strip 10a of the assembly is connected by stapling to the parallel strips 13, each time using two staples 14a and 14b, in order to ensure a more resistant assembly of this strip 10a which will be placed in top or bottom of the roof and will therefore undergo all the pulling of the installation of the batten assembly which is carried out by pulling on the strips 13 from the batten placed at the bottom after nailing the batten 10a on the top of the roof.
  • the sheet 12 which has good resistance to tearing or tearing from its fixing points on the battens 10 under the strips 13, is mounted loose between two parallel strips 13 corresponding to two rafters 11 of the roof.
  • the length of the flexible sheet between two contiguous strips 13 is thus significantly greater than the length of the battens 10, relatively rigid in the axial direction, separating the two contiguous strips.
  • the load of water or other material acting on the channel 15 is supported by the pinching of the flexible sheet 12 between the thin strip 13 and the strip 10, this pinching being further increased by the tightening of the nails 16 for fixing the strips 10 on the rafters 11. These nails punctually cross the sheet 12 and the strips 13 coming to be inserted in the rafters 11.
  • the load of the cover (not shown) placed above the battens (tiles, slates, etc.) increasing further in use the pinching of the flexible sheet 12 between the batten 10 and the strips 13, there is no risk of seeing the sheet 12, made of a resistant flexible material such as polyane or other synthetic material, in particular a waterproof material but porous to air to allow ventilation, tear under the effect of the water load or the wind applied to it.
  • perforations 17 are provided at a distance from the bottom 18 of the channel 15, preferably in the vicinity of the parallel strips 13. These perforations which can be produced at the time of manufacture of the assembly by stapling strips 13 on the battens 10, provide ventilation for the part of the roof situated above the rafters 11.
  • the sheet 12 is provided before its fixing to the battens 10 with perforations 19 (produced for example by a heated tip) whose total section is small compared to the surface of the sheet and which are each surrounded by a flange 20 projecting from the side of the sheet looking outwards when laid, that is to say from the side of the batten.
  • perforations 19 produced for example by a heated tip
  • the sheet 12 is provided before its fixing to the battens 10 with perforations 19 (produced for example by a heated tip) whose total section is small compared to the surface of the sheet and which are each surrounded by a flange 20 projecting from the side of the sheet looking outwards when laid, that is to say from the side of the batten.
  • the continuous flexible sheet 12 largely extends beyond all of the battens 10, not only laterally so as to allow the covering of two assemblies placed side by side on a roof, but especially at the two ends of the to unroll (see the upper end 12a).
  • This end overflow 12a in fact makes it possible to cover the ridge of the roof by folding down the protruding strip which is placed on the other side of the roof.
  • the roof ridge is thus covered, as a temporary cover, with two layers 12a of continuous sheet superimposed and folded down each on the other side.
  • the folded-down parts are generally cut to ensure high-flow ventilation of the roof ridge.
  • the protruding strip (identical to the strip 12a but not shown) is used to discharge outside the rainwater which flows on the continuous flexible strip operating in temporary cover and to bring back leaks that accidentally occur when the continuous strip fulfills the function of sub-roofing.
  • the bar 22 of the staples 14 with U-section is connected by two branches cut into a point 23, 24 whose pointed face is directed at a bevel 25 outwards. Thanks to this arrangement of the staples 14, during the stapling by pressure on the bar 22 of the U, the branches of the staple penetrate into the wood or the synthetic material of the batten 10 by orienting itself, at least in part, parallel to the axis of the batten 10 and even returning in a hook on themselves, as shown in 23 and 24 in FIG. 2.
  • the clip 14 is thus nevertheless deeply anchored in the material of the batten and exerts a significant and persistent pressure over time on the flexible strip 13 by tightening the flexible sheet 12 indirectly well, which is opposed to the tearing of the flexible sheet subjected to traction.
  • the batten assembly according to the invention is generally delivered and transported in a roll corresponding to the standard length of a roof panel.
  • the assembly is unrolled on the roof to the bottom where the last batten is placed, after slight traction on the assembly and lateral orientation, just at the position provided at the bottom of the standard roof panel.
  • the first series of battens is aligned on the edge of the roof while the second series of battens is placed next to the first series on the same rafter. It is possible, in the event of too great a shift, to simultaneously cut the battens on the two series, substantially in the center of the rafter, avoiding reaching the flexible sheet 12.
  • the sheet continuous flexible 12 constitutes not only a wall for collecting and evacuating rain and bad weather but also, in first insulation, a wall separating the interior from the external environment in contact with which are placed permanently the roofing (tiles, slates etc) and the assembly of battens according to the invention which thus participates after its installation, not only in the putting out of water, but also in the general insulation of the building.
