Definitions

  • the invention relates to the technical field of so-called sloping roofs made from tiles or slates arranged on a building frame. More particularly, the invention relates to a roof accessory, such as a closing.
  • Plain square tiles and slates are elements arranged on the framework and assembled together to form a roof.
  • Plain square tiles can be made of terracotta, concrete or synthetic material, and slates can be made of natural slate or synthetic cement-based slate.
  • the roof comprises at least one side and preferably two sides covered with plain square tiles or slate. Each side is inclined at a determined angle.
  • the roof includes a ridge line in the upper part of the pan. This ridge line follows the same direction as the ridge purlin of the roof frame of the building. Conventionally, the ridge line consists of specific ridge tiles compared to plain square tiles covering the roof section by their shape, their positioning on the roof and their function.
  • plain square tiles and slates The primary function of plain square tiles and slates is to form a layer impermeable to bad weather, and more particularly to the penetration of rainwater into the home. This sealing is obtained either by interlocking the plain square tiles one on top of the other by baffles, or by a high rate of overlap of the plain square tiles or slates one on top of the other. In all cases, the necessary waterproofing to rain also results in airtightness.
  • the ridge tiles cover the ridge, the upper part of the roof corresponding to the ridge formed by the meeting between the two sides of the roof, for aesthetic purposes and with the objective of watertightness.
  • the ridge tile seals off the upper junction line of two roof sections, and thus becomes a dividing line and rainwater evacuation.
  • Ridge tiles are curved, rounded, angular or even hat-shaped tiles which are arranged astride the top of the two sides of the roof.
  • This part arranged under the ridge tiles, is generally in the form of a very long profile with an inverted V-shaped section extending generally over the entire ridge line of the roof.
  • the closing is obtained by a flexible sheet, sometimes embossed transversely, which is unrolled along the ridge line and which is folded symmetrically on each section of the roof or by long rigid elements formed of a metal sheet extended on the longitudinal side edges by two flexible, embossed flaps placed on each side, these flaps being folded down symmetrically on each roof panel.
  • the closing fitting the surface of the roof provides sufficient waterproofing to water and air.
  • the middle part of the closure is perforated.
  • the escaping air is blocked under the ridge line and it is difficult to raise these ridge lines to allow the air to pass without also letting through the water from the precipitation pushed by the wind.
  • the required ventilation section is not controlled and often insufficient.
  • a known alternative consists of providing the ridge with protruding support points to lift them, but this modification leads to costly production tools, and the manufacture of the ridge becomes more difficult.
  • the object of the invention is to remedy all or part of the aforementioned drawbacks and in particular to allow ventilation of the roof at the level of the ridge line while protecting itself from water inlets and respecting the general aesthetics of the roof. .
  • the closure of the invention allows a watertight connection of the roof sections while improving the ventilation under the roof by the double ventilation operated directly under the ridge tiles thanks to at least one opening made on the central portion of the closure and to the base of the ridge tiles thanks to at least one ventilation opening fitted each side fin.
  • the closing is largely covered by the succession of ridge tiles forming the ridge line.
  • the first part of each fold of each side fin makes it possible to mimic the thickness of a plain square tile placed under the ridge. This configuration makes it possible to maintain the aesthetics of the roof up to the ridge line.
  • the closure comprises a first face intended to be covered by a ridge tile and a second opposite face intended to be opposite the roof and the framework.
  • the closing device is a part preferably made of metal, for reasons of manufacturing costs.
  • the closure according to the invention can be made of plastic.
  • the closing device is in the form of an elongated profile along a longitudinal axis.
  • the closure has the overall shape of an inverted “V”.
  • the profile of the closure is symmetrical along a median longitudinal axis X-X.
  • the length of the cap is about 2 meters, depending on the embodiment and the size of the ridge line to be covered.
  • several closoirs are arranged on the ridge line, one after the other.
  • the closure has a first end and a second end.
  • the first end is straight in the direction of the length, as if it were cut clean in a plane perpendicular to its length.
  • the second end is asymmetrical with respect to the first end along a median transverse axis Y-Y.
  • the second end has an extension of each lateral fin over a determined length, each extension being shaped to cover and / or cooperate with the lateral fins of an adjacent closing, that is to say aligned side by side lengthwise.
  • the upper portion is intended to overlap the extension rail of the frame.
  • the upper portion is flat, preferably narrow, intended to be placed in a centered manner on the ridge line of the frame.
  • each side of the central portion is inclined.
  • each side of the central portion is inclined from the flat upper portion, at an angle that is neither flat nor straight, and preferably at an angle of between 15 ° and 60 °.
  • each side of the central portion comprises a plurality of openings distributed over the length of the closure.
  • the openings are preferably regularly distributed and regularly spaced.
  • each opening can have an identical or different shape.
  • each opening can be in a circular or ovoid shape or any other shape suitable for the air discharge.
  • each opening can be equipped with a louver, in order to prevent any possible infiltration of water between two ridge tiles from falling directly into the openings.
  • the opening (s) are configured to ventilate the air remaining under the ridge tiles.
  • the openings contribute to the weakening of the closure, by a loss of rigidity, which makes the flexible closure at the level of the openings and in particular at the level of the inclined face accommodating said openings. This flexibility makes it possible to vary the spacing of the closure and the distance between the two fins by deformation.
  • the central portion comprises two steps, each step is positioned at one end of a side of the central portion.
  • Each step is configured to stop any upwelling of water from precipitation that can infiltrate under the ridge, and be pushed by the wind.
  • each fin is connected to a side of the central portion by one of the steps.
  • each fin extends in a plane substantially parallel to that of the roof.
  • each fin is shaped to cooperate with the base of a ridge tile.
  • the first part of each fold of each fin is generally perpendicular to the inclined portion of the fin.
  • the inclination of the inclined portion is oriented towards the roof.
  • the first part of each fold of each fin is equipped with the at least one ventilation opening and preferably a plurality of ventilation openings.
  • each ventilation opening comprises a louver oriented towards the roof, which makes it possible to prevent water infiltration through these openings and thus protect them from spraying rainwater.
  • the ventilation openings are advantageously oriented in a determined direction, so that the precipitation does not infiltrate the ventilation openings.
  • the ventilation openings are preferably arranged over the entire length of the closure.
  • the ratio of the length of a ventilation opening relative to the length of a first fold-back part is at least 50%.
  • the height of the ventilation openings is at least 4mm and even more preferably between 4mm and 10mm.
  • the ventilation openings are embossed by cutting and / or by deformation of the first part of the fold of each fin.
  • the second part of the fold constitutes a return towards the interior of the closure.
  • the second part of the fold is intended to cooperate with the surface of the roof and more particularly is intended to be arranged on the plain square tiles or flat slates constituting the roof.
  • the second part of the fold has a determined width so that the second part of the fold has a contact sufficient with the surface of the square tiles or slates constituting the roof, so as not to allow precipitation to penetrate.
  • the fold can comprise at least one compensation member positioned under the second part of the fold in order to compensate for the variations in thickness of the plain square tiles or slates of the roof.
  • the compensation member is configured to locally create contact with the plain square tile or slate in the event of a variation in the thickness of the roof.
  • the compensation member is a bead or a tongue or a part of elongated shape optionally made of an elastically deformable material such as a foam or an elastomer bead.
  • the compensation member can be configured to secure the closure to the roof and acts as a seal.
  • the subject of the invention is also a roof assembly comprising at least one closing according to the invention and a ridge tile partially, preferably predominantly, covering said closing.
  • the roof assembly comprises a plurality of ridge caps one after the other along a longitudinal ridge line, the plurality of ridge tiles is covered by a plurality of ridge tiles.
  • the air admitted under the surface of the roof travels by convection to the top of the latter and emerges mainly through the at least one ventilation opening. Part of the air passes through the at least one opening in the central portion, which allows the interior of the ridge tiles to be ventilated.
  • the closures of the roof assembly are identical.
  • the closing 10 is configured to be positioned under at least one ridge tile of a line of ridge tiles of a roof.
  • the ridge line of a roof is covered with a plurality of closures, preferably identical, aligned longitudinally along the ridge line.
  • the closures thus aligned form a line of closures, covered by ridge tiles aligned one after the other longitudinally, along the ridge line. This configuration is illustrated in figure 4 .
  • the closure 10 illustrated comprises a first face intended to be covered by a ridge tile 101 and a second opposite face intended to be opposite the roof 103 and the frame.
