Description

Technical field

[0001] The present invention relates to a sealing device capable of being placed under a layer of tiles, or any other covering element, of a roof in order to ensure sealing at the level of an air outlet of a ventilation system of the VMC type or similar, said sealing device advantageously replacing a socket tile. State of the art

[0002] In the field of residential buildings, or buildings for professional use, particularly for tertiary activities, it is well known that these buildings can have a tile roof resting on a framework. The tiles are often made of terracotta, but also of concrete, or of a synthetic material such as a resin. Battens are installed fixed to the framework transversely to the slope of the roof, spaced regularly, receiving on each one a row of tiles. The tiles meet different aesthetic criteria depending on the region. Through their shapes, colors and sizes, the tiles contribute to forming a style and identity for the homes of a region.

[0003] Among others, we find, for example in the South, interlocking tiles called strongly curved, such as Roman tiles which, once laid, resemble canal tiles. We also find, rather in the North and the Center, interlocking models called weakly curved, commonly called mechanical tiles. Finally, we find tiles without any interlocking, called flat tiles, whose watertightness is obtained by a strong mutual overlap.

[0004] Furthermore, given the high level of thermal insulation required for heating buildings, and the resulting airtightness of the entire building, it is common to use ventilation methods such as controlled mechanical ventilation known as "CMV". Air is admitted at different points in the building, it is then extracted in a controlled manner by a motorized turbine, and generally expelled through air outlets in the roof. For air outlets in the roof, it is usual to use a specific tile, called a socket tile, with a general shape and dimensions identical to the other tiles on the roof to fit like other standard tiles in a section of the roof.

[0005] Such a socket tile has in its center a substantially vertical circular contour, produced by an upward deformation of the surface, which ends in a horizontal crown having in the center a circular passage.

[0006] The horizontal crown receives a hat called a lantern, comprising a generally cylindrical shape arranged vertically, including a closed top to prevent water from entering, and a vertical contour presenting a series of openings allowing the extracted air to exit.

[0007] It is therefore clear that it is necessary to have a specific socket tile model for each tile model, so the manufacturing cost of these socket tiles is particularly high.

[0008] In addition, needs are evolving and leading to a demand for reducing air pressure losses in the VMC stale air extraction circuit.

[0009] One solution to reduce the air pressure losses of the circuit is to increase the diameter of the outlet on the roof, therefore downstream of the ventilation unit. In this respect, the regulations have evolved in this direction, by prohibiting any outlet with a diameter less than 125 and 160 mm, depending on the case, or at least by limiting the pressure loss of this outlet (outlet + lantern) to 25 Pa.

[0010] To allow a larger through diameter, one possible solution is to replace the terracotta protrusion carrying the lantern with a plastic protrusion glued tightly to the surface of a tile previously drilled to the correct diameter.

[0011] This is the case of French patent application FR3062663, filed by the applicant, which describes a socket tile for a building roof, intended to be arranged in the middle of standard tiles. Said socket tile comprises a pierced tile and a plastic bulb extending the drilling of this tile, the base of the bulb comprising a contour fitting into the drilling of the pierced tile and comprising, around the contour, a continuous peripheral edge which has a lower end which approaches the upper surface of this pierced tile, forming below a channel receiving a bead of glue.

[0012] The low thickness of the plastic, around 2 mm instead of 10-13 mm for terracotta, and the lesser clearance required for demolding lead to a larger useful diameter. This can provide a solution for large format tiles, therefore with a large useful length and a large useful width. For these large tiles, the available dimensions excluding mutual overlap with the surrounding tiles allow the passage of a 160 mm insulated ventilation duct + insulation without interfering with the mutual overlap areas of the tiles, high, low and side. Interfering with these areas means having to cut them locally, which results in a loss of roof waterproofing, leading to water infiltration.

[0013] However, it is not always possible to provide a hole with a diameter of 160 mm on a tile, or even more if there is insulation around the ventilation duct, depending on the format of the tiles, the shape of the tiles or the spacing of the battens supporting the tiles. Small and medium formats pose difficulties in accommodating a hole with a diameter of 160 mm and prohibit going beyond this.

[0014] Document DE19518746 discloses a sealing device according to the preamble of claim 1. Disclosure of the invention

[0015] One of the aims of the invention is therefore to remedy these drawbacks by proposing a sealing device capable of being arranged under a layer of small covering elements forming a roof, of simple and inexpensive design, providing increased sealing against water flow, intended to allow a ventilation duct to pass through and capable of receiving a ventilation lantern, thus replacing a socket tile.

[0016] For this purpose, and in accordance with the invention, a sealing device is provided according to claim 1. The sealing device is capable of being arranged under a layer of small roofing elements, such as tiles, forming a roof comprising a plurality of rows (n, n+1, etc. from the bottom to the top of the roof), said roofing elements each comprising an external face facing the sky and an internal face facing a frame and being placed on rows of battens of the frame, the sealing device comprising at least: a central portion which is substantially planar, two longitudinal partitions located on either side of the central portion, the two longitudinal partitions extending from the external face of the central portion and laterally delimiting the central portion, a foot portion capable of cooperating with a head portion of at least one n-1 row covering element of the roof by bearing on the latter, two lateral portions arranged on either side of the central portion, each of the lateral portions being separated from the central portion by one of the longitudinal partitions, each of the lateral portions comprising a lateral edge which is oriented upwards and which extends at least partly along a lateral edge of the respective lateral portion, and a ventilation portion which is tubular and which projects from the external face of said central portion, the ventilation portion being configured to house at least partly a ventilation duct,the ventilation portion comprising a lower end opening which opens into the internal face of said central portion and which is intended to allow the ventilation duct to pass, and an upper end opening, the ventilation portion being capable of receiving a ventilation lantern, , each of the longitudinal partitions being provided with breakable portions which are pre-cut vertically, so as to be able to adapt the length of each of the longitudinal partitions.

[0017] In the event of rain, the majority of the rainwater, which flows from the n+1 row covering elements located upstream of the waterproofing device, falls by gravity onto the central portion of the waterproofing device, and is channeled and guided towards the foot portion of the waterproofing device by the two longitudinal partitions located on either side of the central portion. The rainwater, channeled and guided by the two longitudinal partitions, is evacuated onto the head portion of the n-1 row covering elements located downstream of the waterproofing device, under the surface of the two n row covering elements located on either side of the waterproofing device.

[0018] A small portion of the rainwater, which flows from the n+1 row covering elements located upstream of the waterproofing device, can penetrate along the outer faces of the longitudinal partitions, between these longitudinal partitions and the two n row covering elements located on either side of the waterproofing device. This flow is then channeled and guided towards the foot edge of the two lateral portions by the two lateral edges and the two longitudinal partitions, and is evacuated onto the n-1 row covering elements located downstream of the waterproofing device.

[0019] Thus, the sealing device according to the present invention avoids any risk of water infiltration at the junctions of the sealing device and the covering elements located near the latter, and therefore provides perfect sealing against water flow.

[0020] The sealing device may further have one or more of the following features, taken alone or in combination.

Method of carrying out the invention

[0052] In the following description of the sealing device according to the invention, the same numerical references designate the same elements. The different views are not necessarily drawn to scale.

[0053] THE figures 1 to 8 represent a sealing device 1 according to a first embodiment of the invention, which is capable of being arranged under a layer of small roofing elements 2, such as standard tiles, forming a roof comprising a plurality of rows (n, n+1, etc. from the bottom to the top of the roof). The roofing elements 2 each comprise an external face facing the sky and an internal face facing a frame, and are placed on rows of battens 3 of the frame.

[0054] The sealing device 1 comprises a main body 5 having a generally rectangular shape. The main body 5 may for example be made of synthetic material, and for example of injected plastic. However, the main body 5 could also be made of metallic material.

[0055] The main body 5 comprises a central portion 6 which is substantially planar and which is configured to be centered on the lateral junction between two covering elements 2 of rank n-1, when the covering elements 2 are laid using a cross-joint installation.

[0056] The main body 5 also comprises two longitudinal partitions 7 located on either side of the central portion 6. The two longitudinal partitions 7 extend substantially vertically from the external face of the central portion 6 and laterally delimit the central portion 6. Each of the longitudinal partitions 7 extends over all or part of the length of the central portion 6. Advantageously, each of the longitudinal partitions 7 extends from the leading edge of the central portion 6 and towards the footing edge of the central portion 6.

[0057] According to the first embodiment of the invention, each of the two longitudinal partitions 7 has a height substantially equal to the thickness of the covering elements 2, and for example approximately 25 mm. According to the invention, each of the two longitudinal partitions 7 is provided with breakable portions 8 which are pre-cut vertically, so as to be able to adapt the length of each of the longitudinal partitions 7.

[0058] The main body 5 also comprises two lateral portions 9 arranged on either side of the central portion 6. Each of the lateral portions 9 is separated from the central portion 6 by one of the longitudinal partitions 7, and is configured to be at least partially covered by a covering element 2 of rank n.

[0059] Each of the lateral portions 9 comprises a bottom wall 11 which is substantially planar and which is substantially parallel to the central portion 6, and a lateral rim 12 which is oriented upwards and which extends at least partly along a lateral edge of the respective lateral portion 9. Advantageously, each of the lateral rims 12 extends substantially vertically, and each bottom wall 11 is delimited laterally by the respective lateral rim 12 and by the respective longitudinal partition 7.

[0060] According to the first embodiment of the invention, each lateral portion 9 further comprises a lateral support part 13 which is configured to bear on a batten 3 of row n, and which extends over all or part of the length of the respective lateral portion 9. In order to allow the lateral support parts 13 to be placed on the row of battens 3 of row n, said row of battens is interrupted.

[0061] Advantageously, each lateral support portion 13 is flat and horizontal. According to the first embodiment of the invention, the lateral support portions 13 and the central portion 6 are parallel, and for example coplanar, and each lateral portion 9 comprises a horizontal extension which extends from the respective lateral rim 12 and which forms the lateral support portion 13 of the respective lateral portion 9.

[0062] As shown on the Figure 1 , the longitudinal partitions 7, the bottom walls 11 of the lateral portions 9 and the lateral edges 12 delimit two lateral water flow channels 14. Advantageously, the central portion 6 is raised relative to the bottom of each of the lateral water flow channels 14, and the downstream end of each lateral water flow channel 14 comprises a water evacuation ramp 15 which is inclined upwards.

[0063] According to the embodiment shown in the figures 1 to 8 , each lateral water flow channel 14 has a width which is reduced in the upstream portion of said lateral water flow channel 14, to leave room for the respective lateral support portion 13. These arrangements make it possible to obtain a main body 5 having a generally rectangular shape. However, according to an alternative embodiment of the invention, each lateral water flow channel 14 could have a constant width over its entire length.

[0064] The main body 5 also comprises a transverse partition 16 extending substantially vertically along the leading edges of the central portion 6 and the two lateral portions 9 and from the external faces of the central portion 6 and the two lateral portions 9. Advantageously, the transverse partition 16 closes the central portion 6 and the lateral portions 9 near the leading edges of the central portion 6 and the two lateral portions 9.

[0065] As shown more particularly on the figures 3 And 6 , the main body 5 further comprises a foot portion 17 capable of cooperating with a head portion of at least one covering element 2 of rank n-1 of the roof by bearing on the latter.

[0066] The sealing device 1 further comprises a ventilation portion 18 which is tubular and which projects from the external face of the central portion 6. Thus, the longitudinal partitions 7 extend on either side of the ventilation portion 18. Advantageously, the ventilation portion 18 has a height greater than 2.5 times the thickness of the covering elements 2, and this so as to extend beyond the covering elements 2 of rank n+1.

[0067] According to the first embodiment of the invention, the ventilation portion 18 is located in the downstream half of the central portion 6, and consists of a bulb in the form of a truncated tube. Thus, the ventilation portion 18 has a generally truncated shape, and has a cross-section which is circular. However, according to an alternative embodiment of the invention, the ventilation portion 18 could have an oval or even polygonal section, such as square or rectangular, and for example have a generally pyramidal shape.

[0068] Advantageously, the main body 5 and the ventilation portion 18 are in one piece. In other words, the ventilation portion 18 is advantageously made of the same material as the main body 5.

[0069] The ventilation portion 18 is more particularly configured to house at least in part a ventilation duct. Advantageously, the ventilation portion 18 comprises a lower end opening 18.1 which opens into the internal face of said central portion 6 and which is intended to allow the ventilation duct to pass, and an upper end opening 18.2 configured to allow the evacuation, towards the outside of the cover, of the air flow coming from the ventilation duct.

[0070] The vent portion 18 is also configured to receive and support a vent lantern 19 (see figure 8). In a known manner, the ventilation lantern 19 comprises a base configured to fit on the upper end portion of the ventilation portion 18, a peripheral wall provided with air discharge openings, and an upper cover, for example domed, configured to prevent rainwater from entering the air discharge openings.

[0071] The sealing device 1 further comprises a flexible foot extension 21 extending the foot portion 17. The flexible foot extension 21 is integral with a foot edge of the foot portion 17, and is intended to be mounted on the leading edge of at least one covering element 2 of the row n-1. The flexible foot extension 21 may extend, continuously or discontinuously, over all or part of the foot edge of the foot portion 17, and may have, for example, a width L of between 30 and 120 mm.

[0072] According to one embodiment of the invention, the flexible foot extension 21 comprises on its internal face an adhesive layer, for example made of butyl, in order to allow the flexible foot extension 21 to be bonded to the external face of the leading edge of the covering element 2 of the n-1 row and to ensure a sealed connection between the sealing device 1 and said covering element 2 (even if the covering elements 2 have imperfections or shape details creating discontinuities). According to an alternative embodiment of the invention, the flexible foot extension 21 could however consist of a lead strip or an embossed aluminum strip.

[0073] As shown on the figures 5 And 7, the two cover elements 2 of row n arranged on either side of the sealing device 1 are each cut so as to be able to bypass the ventilation portion 18 of the sealing device 1. More precisely, each of the aforementioned cover elements 2 of row n is cut so as to have a notch extending from a head edge of the respective cover element 2 and from a lateral edge of the respective cover element 2. The two notches are more particularly made so as to preserve the foot edges of the two aforementioned cover elements 2 and also to preserve at least in part the interlocking means provided on the two cover elements 2 and configured to cooperate together. After cutting, the two cover elements 2 respectively have a generally L-shape and a generally inverted L-shape.

[0074] When installing each of the two cover elements 2 that have been cut, the longitudinal edge of the respective notch is aligned with an external face of a respective longitudinal partition 7 of the sealing device 1. To guarantee the stability of the two cover elements 2 that have been cut, the latter are advantageously fixed, for example by screwing into the row of battens 3 of row n, or even onto the lateral support parts 13 of the sealing device 1.

[0075] The cover elements 2 of rank n+1 are then laid normally, or if necessary, the two cover elements 2 of rank n+1 intended to cover the sealing device 1 can also be notched in a mirror image in their downstream part in order to be able to bypass the ventilation portion 18 of the sealing device 1. In the event that these two cover elements 2 of rank n+1 come into conflict with the longitudinal partitions 7 of the sealing device 1, the longitudinal partitions 7 could be cut on demand (by cutting the breakable portions 8).

[0076] In the event of rain, the rainwater, flowing from the cover elements 2 of rank n+1 located upstream of the sealing device 1, will fall on the central portion 6 of the sealing device 1 and on the two cover elements 2 of rank n cut out and located on either side of the sealing device 1. Given the presence of the two longitudinal partitions 7, the water falling by gravity on the central portion 6 of the sealing device 1 is guided towards the foot edge of the central portion 6, and is evacuated onto the head part of the cover elements 2 of rank n-1, under the surface of the two cover elements 2 of rank n cut out and located on either side of the sealing device 1.

[0077] A small part of this flow can penetrate along the outer faces of the longitudinal partitions 7, between these longitudinal partitions 7 and the two cover elements 2 of row n located on either side of the sealing device 1. This flow is then collected in the lateral water flow channels, blocked by the lateral edges 12 and will be evacuated via the water evacuation ramps 15 on the cover elements 2 downstream. Thus, the configuration of the sealing device 1 prevents any infiltration of water at the level of the sealing device 1.

[0078] For aesthetic purposes, the sealing device 1 may be at least partially covered by a covering portion 22. As shown in the figure 8, the covering portion 22 is configured to at least partially cover the central portion 6 and the longitudinal partitions 7 of the sealing device 1. For this purpose, the covering portion 22 comprises a central opening 23 intended for the passage of the ventilation portion 18.

[0079] Advantageously, the covering portion 22 comprises two downwardly oriented lateral edges. Each lateral edge of the covering portion 22 is configured to extend between the external face of a respective longitudinal partition 7 of the sealing device 1 and one of the cover elements 2 of row n which has been cut out.

[0080] There figure 9 represents a sealing device 1 according to a second embodiment of the invention which differs from the first embodiment essentially in that it comprises a head extension 24 configured to bear on a row of battens 3 of row n.

[0081] The head extension 24 may for example be substantially flat and horizontal, and extend along all or part of the head edge of the central portion 6. According to such an embodiment of the invention, the lateral portions 9 are devoid of a lateral support part.

[0082] Finally, it is quite obvious that the examples which have just been given are only particular illustrations and in no way limitative as to the fields of application of the invention which is defined by the appended claims.
