104) SLEEVE TILE FOR A BUILDING COVER PROVIDED WITH BULB BONDING PROTECTION.

FR 3 062 663 - A1 _ The subject of the invention is a socket tile for a building covering, intended to be placed in the middle of standard tiles (2), this socket tile (20) comprising a perforated tile (22) , and a bulb (24) extending the drilling of this pierced tile (22), characterized in that the base of the bulb (24) has a contour which fits into the bore of the pierced tile (22), and has around this contour a continuous rim (26) having an end which approaches the upper surface of this pierced tile (22), forming below a channel receiving a bead of glue (28).

SLEEVE TILE FOR A BUILDING COVER PROVIDED WITH BULB BONDING PROTECTION

The present invention relates to a roof tile for a building roof, as well as a method of manufacturing this roof tile, and a building roof comprising such roof tiles.

Buildings for residential use, or for professional use, in particular for tertiary activities, may have a tiled roof resting on a frame. The tiles are often made of terracotta, but also of concrete, or of synthetic material such as a resin.

We install battens fixed on the frame transversely to the slope of the roof, spread evenly, receiving on each a row of tiles.

The tiles meet different aesthetic criteria depending on the region. Through their shapes, colors and sizes, the tiles help to form a style and an identity for the homes of a region.

In addition, given the high level of thermal insulation necessary for heating buildings, and the airtightness of the entire building which results, it is common to use ventilation means such than mechanical ventilation controlled "VMC". Air is admitted at different points in the building, it is then extracted in a controlled manner by a motorized turbine, and generally expelled by exits in the roof.

For air outlets it is known to use a specific tile, called a roof tile, having a general shape and identical dimensions to be inserted like the other standard tiles in a section of the roof.

The socket tile has in its center a substantially vertical circular outline, produced by an upward deformation of the surface, which ends in a horizontal crown having in the center a circular passage.

The horizontal crown receives a hat called a lantern, comprising a generally cylindrical shape arranged vertically, comprising a closed top to prevent water ingress, and a vertical contour having a series of openings allowing the exit of the extracted air.

A problem which arises with this type of roofing tile and that it is produced in very small quantity compared to the other standard roofing tiles, whereas it is necessary for aesthetic reasons to be able to propose it with all the variants of aspects and colors shown on these standard tiles.

The complicated shape of these socket tiles requires specific production tools which are expensive to produce. In addition it is necessary to maintain a stock available in all the variants of aspects and colors, which involves significant costs.

As a variant, a type of known socket tile, presented in particular by document EP-A1-2759652, has a generally flat shape similar to other standard tiles, having a central opening comprising a small rim of constant height around its contour. A plastic insert added to the opening is fixed by gluing or clipping on it.

However, the small edge on the outline of the opening of this tile is simpler to manufacture than a circular shape extending over the height, but still requires specific tools, and keeping in stock these particular tiles according to all variants, which results in costs.

As a variant, another type of known socket roof tile, presented in particular in document DE-U1-29815502, comprises a roof tile having an entirely standard shape, in which an opening has been made for the passage of a vertical sleeve, intended to receive inside an extraction air passage duct. The junction of the vertical sheath and the tile receives a bonding bead on the complete periphery of this sheath, in order to ensure mechanical support and sealing.

However, this type of adhesive bonding disposed on top of the socket tile presents aging problems which can reduce the life of this tile. In particular, the ultraviolet radiation from the sun degrades the qualities of the adhesive over time, it may result in leaks of rain water trickling onto this tile which infiltrate through the degraded bonding, or a takeoff of the sheath.

The object of the present invention is in particular to avoid these drawbacks of the prior art.

To this end, it offers a socket tile for a building covering, intended to be placed in the middle of standard tiles, this socket tile comprising a pierced tile, and a bulb extending the drilling of this pierced tile, this socket tile being remarkable in that the base of the bulb has a contour which adjusts in the drilling of the pierced tile, and comprises around this contour a continuous rim having an end which approaches the upper surface of this pierced tile, forming in below a channel receiving a bead of glue.

An advantage of this socket tile is that it can be cut in the middle of a standard tile to obtain the pierced tile, which allows the use of standard tiles kept in stock according to all their variants.

Then simply put in the channel inside the rim a continuous bead of glue, then press the bulb on the pierced tile by centering it around the outline of the base adjusting in the hole. The bead of glue fixing on the top of the tile around the cut, constitutes an effective fixing means, ensuring a tightness on the complete contour, which is protected in particular from mechanical aggressions and ultraviolet radiation by the rim completely covering it .

The perforated tile produced from a standard tile manufactured in large series with all the necessary nuances, not requiring any particular storage, makes it possible to avoid specific tools for molding a socket tile, as well as inventory management. of different tiles. We cut costs.

The tile according to the invention may further include one or more of the following characteristics, which can be combined with one another.

Advantageously, the continuous flange comprises in a cross section a part facing radially outwards, then a descending part directed towards the top of the pierced tile.

In this case, the channel below the continuous rim may have a generally rectangular cross section with a side which may be biased.

Advantageously, the bulb comprises, above the continuous rim, a conical shape which narrows, then a horizontal crown having a central bore.

Advantageously, the bulb is formed in one piece by molding.

In this case, the bulb can be formed by molding in a mold having an opening along a vertical axis.

Advantageously, the cutout of the bore has an edge arranged vertically when the pierced tile is inclined along the slope of the roof.

The invention also relates to a method of manufacturing a socket tile comprising any one of the preceding characteristics, comprising a step of cutting the central bore on a standard tile to form the pierced tile.

The invention further relates to a roof covering a building comprising roof tiles comprising any one of the preceding characteristics.

Other characteristics and advantages of the invention will emerge on reading the description which follows, given solely by way of example, with reference to the following appended figures:

- Figure 1 is an axial sectional view in the longitudinal direction of a socket tile according to the prior art;

- Figure 2 is an axial sectional view in the longitudinal direction of a socket tile according to the invention;

- Figure 3 shows the tile pierced with this socket tile;

- Figure 4 shows the bulb of this socket tile; and

- Figure 5 shows in axial section the continuous rim of this bulb containing the bonding.

For the sake of clarity, identical or similar elements are identified by identical reference signs in all of the figures.

Figure 1 shows a cover with standard tiles 2 held on battens 4 of the frame to form rows of tiles, surrounding a socket tile 6 having in the center an elevation of the surface 8 of slightly conical shape tightening upwards , forming a circular outline around a vertical axis A.

The surface elevation 8 ends with a horizontal crown 10, having a central bore receiving the air flow from an aeration tube 18 which once installed arrives a little below this crown.

A molded lantern 12 has a generally cylindrical shape, comprising at the base a flare provided for fitting on the crown 10 of the socket tile 6. Above the flare, a straight cylindrical surface has a series of vertical slots 16, protected by a domed upper closure 14 projecting around this cylindrical surface to prevent rainwater from entering the slots.

The sleeve tile 6 requires specific molds to make it, comprising the circular contour of the elevation of the surface 8. It is in particular necessary to make moldings of these sleeve tiles 6 in all the possible appearance variants included in the standard 2 tiles, and maintain stocks to meet customer demands. These features represent a significant cost.

FIG. 2 shows a socket tile 20 comprising a pierced tile 22 having a shape and an appearance identical to those of standard tiles 2, receiving on a central bore a bulb 24 having in the upper part the horizontal crown 10 receiving below its bore central the ventilation tube 18.

The contour of the base of the bulb 24 has a continuous rim 26 fitted on top of the pierced tile 22, containing inside a bead of continuous glue 28, which is glued on top of this pierced tile so as to ensure a tightness and mechanical strength on this complete contour.

Figure 3 shows the pierced tile 22 formed with the same mold as a standard tile 2, comprising an upper surface visible after mounting the cover, comprising looking at the lower edge 40, on the left a flat part 30, and on the right a curved portion 32 of reduced width relative to this planar portion.

The left edge of the pierced tile 22 has a longitudinal groove 34 ending in a rim, receiving the right edge of the adjacent tile in order to form a channel for the flow of rainwater.

The upper edge of the pierced tile 22 comprises two parallel upper ribs 36, 38 delimiting between them a transverse groove which opens on the side in the longitudinal groove 34.

The underside of the lower edge 40 has grooves 42 fitting onto the upper ribs 36, 38 of the adjacent tile of the lower row.

The pierced tile 22 has a circular central bore 44 formed largely on the flat part 30, and projecting over the domed part 32. The central bore 44 can be produced by any cutting means adapted to the material of a standard tile 2, including in particular machining with a cutting tool, stamping with a press tool, or other cutting methods such as laser cutting or water jet cutting.

In particular, the central hole 44 can be cut to form an edge 46 of this cut arranged vertically when the pierced tile 22 is inclined along the slope of the roof, which is generally between 20 and 45 °.

The central bore 44 may be circular, or have any other shape, in particular an oval shape, along the contour of the bulb 24 to be adjusted therein.

Figures 4 and 5 show the bulb 24 which can be made of any material, in particular by molding a plastic material.

The bulb 24 has at its base a contour 50 which adjusts in the bore 44 of the pierced tile 22, with minimum clearance so as to position this bulb.

In particular the base of the contour 50 can form a vertical cylinder, fitting into the edge 46 of the central bore 44 which is also cut along a vertical when the pierced tile 22 is inclined in its mounting position.

The continuous rim 26 surrounding the base of the contour 50, comprises a first part facing radially outward 52, disposed generally in a plane parallel to the surface of the pierced tile 22, then a second descending part 54 coming close to this tile , which is perpendicular to the first part. As a variant, the second descending part 54 can join the surface of the tile 22 in a direction parallel to the axis of the contour 50.

A continuous channel is obtained having a substantially rectangular section with a side which may be oblique depending on the position on the contour, arranged parallel to the surface of the pierced tile 22.

The continuous rim 26 follows the undulations of the surface of the pierced tile 22, in particular the curved part 32, so as to remain at a constant distance from this surface. The channel under the rim 26 has a generally constant section over the whole of its developed.

The bulb 24 allows in particular a molding with a mold having an opening movement in the vertical direction, which has only two elements due to the absence of undercut of this bulb for demolding in this direction. The mold is simple to manufacture, and the production costs of bulb 24 are reduced.

During the manufacture of the socket tile 20, the bulb 24 is turned over and a continuous bead of adhesive 28 is deposited in the channel under the rim 26. Then the bulb 24 is placed on the pierced tile 22 by easily centering it in the hole 44, and it is pressed so as to continuously glue the bead of glue 28 on this tile. During this pressing operation the glue 28 remains in position thanks to the rim 26 surrounding it.

There is thus obtained in a simple, efficient and rapid manner, the finished sleeve tile 20. The rim 26 covering the entire bead of glue 28 protects this glue against mechanical attack, and in particular against exposure to ultraviolet rays.

It will be noted that the pierced tile 22 does not have a thick rim around the bore 44, the bulb 24 glued continuously around this bore constitutes an effective reinforcement of this tile in order to reinforce it in its central part which is more fragile.

It will also be noted that the bulb 24 may have relatively thin walls, with a thickness in particular between 1.5 and 3 mm, the base of the contour 50 inserted in the bore 44 occupies a reduced radial distance which makes it possible to provide a large diameter passage of the aeration tube 18. By comparison, the thickness of the surface elevation produced in the same material as the tile for a socket tile according to the prior art, is generally between 8 and 12 mm.
