ES2295535T3 - WIND RESISTANT TILE. - Google Patents

Abstract

The tile, designed to be fixed to roof battens, is made with two stepped sections - an upper section (7) with lateral interlocking channels (10), and a lower section (8) that overlaps the lateral edges of the tile in the row beneath. The front edge (11) of the lower section projects downwards to overlap the front edges of adjacent tiles on either side. The tile can be made in flat, ridged and curved versions.

Description

Windproof tile.

The present invention relates to a tile of lace.

In the field of lace tiles used usually for building coverage, a recurring problem  that arises is that of the resistance to the start by the wind.

Traditionally, lace tiles comprise a top edge called "head edge", an edge bottom called "tail edge", two side edges, one upper surface that can have different shapes or reliefs, and a lower shape usually provided with spikes or studs directed downwards that serve to hook the tile over the slats or the shingles of the structure.

Known tiles usually comprise a throats system whose concavity is turned up and that are arranged along the head edge and along a first lateral edge, and also comprise a system of downwardly oriented flanges arranged along the edge of tail and the second side edge of the tile.

The tail edge of a tile covers the Tilehead throat of the lower row with respect to the direction of the slope of the roof and the side flange covers the Side throat of the adjacent tile. Thus, for a given tile, there is a coating on two edges: the leading edge of the tile and one of its lateral edges.

It has been seen that when the roof is subjected to a strong wind, during a violent storm or during a storm, and in particular when the wind direction is substantially contrary to the slope of the roof or when it blows laterally attacking each tile by the side of its lateral edge not Coated, the risk of starting the tiles is important. In effect, the angle of the tile that is common to the edges not coated is a point of small resistance to lifting, since no weight is applied on this angle.

Solutions have been provided to counteract this inconvenience. Thus, tiles have been proposed that comprise a hook system on the slats or shingles at the level of the common angle to the uncoated edges of the tile. Such hitch it can be done by nailing with the help of a point that crosses the tile from part to part, whose head rests on the surface top of the tile and whose tip is driven into the slat or shingle That supports the tile. The hitch can also be done by harpooned, that is, by means of a hook or loop located in the lower surface of the tile in the region of the uncoated angle of said tile and that is fixed on the slat or the shingle that supports the tile.

A lace tile according to the preamble of the claim 1 is described in DE 539600 C.

In all cases, these solutions are not entirely satisfactory, since they demand an annoying placement and therefore expensive in labor.

The main objective of the present invention is to provide a tile that is very resistant to starting by the wind and avoid the above mentioned inconveniences.

This objective is achieved with a lace tile intended to be placed and fixed on the slats or shingles for realization of a roof comprising an upper surface, a lower surface, a head edge, a tail edge and some lateral edges, the tile also comprising two parts that have substantially the same length, namely:

(i) a general plate-shaped upper part water receiver of the upper row of tiles and that presenting some lace turned up along its head edge and its lateral edges, and

(ii) a lower part located substantially in the extension of the upper part and bordered laterally by two parts covering the side lace of the part upper of the adjacent tiles of the upper row, comprising the tile tail edge a covering lace of the two adjacent shingles, substantially half-length from this one, and from the tile of the lower row in its head socket, the width being from the bottom of the roof tile to the width of the part higher.

Advantageously, the lower part of the tile according to the invention it is stripped down, in its entirety or only in its central zone, with respect to the upper part.

According to a first embodiment of the invention, it is a flat or weakly pumped roof tile, of general rectangular shape.

In any case, the invention will be fine. understood with the help of the description that follows, making reference to the attached schematic drawing presented, by way of non-limiting example, various embodiments of tiles according to the invention.

The examples in figures 1, 2, 3 and 6 are not covered by the claims and are presented not as modes of embodiment of the invention, but as useful examples for the understanding of the invention

The tile 1 represented in figure 1 comprises a head edge 2 and a tail edge 3 corresponding to the small sides of the tile, as well as two lateral edges 4. It comprises a lower face 5 and an upper face 6, whose most part large is a visible surface 6 when several tiles are assembled to form a cover.

The tile 1 according to the invention is a flat tile or weakly pumped to be fixed according to the rules of the branch to slats (or shingles) of a structure in order to form a roof.

It is made in any material adapted to this use, for example composite materials, but more generally mud cooked (clay or other), molded and then cooked to high temperature according to the methods known to the expert.

In order to solve resistance issues at the start by the wind exposed in the preamble, the tile of lace 1, as shown in figures 1 or 2, comprises two parts that have substantially the same length, namely:

(i) a top 7 in general form of plate, water receiver of the upper row of tiles presenting  some lace 10 turns up, along its edge of head 2 and its two lateral edges 4, and

(ii) a lower part 8 located substantially in the extension of the upper part 7 and bordered laterally by two cover parts 11 of the side fittings 10 of the upper part 7 of the adjacent tiles of the lower row, the tail edge 3 of the tile 1 comprising a lace of covering 10 of the two adjacent tiles, substantially to medium length of this one, and of the tile of the lower row in its lace of head 2.

The bottom 8 of the tile 1 is bent down with respect to the top 7, thus creating two upper and lower levels separated by a "nose of movement "12 arranged transversely to approximately half length of the tile.

The tile 1 can be flat, in general rectangular.

When several tiles are assembled as illustrated in figure 2, these overlap so that a single tile gives the appearance of two tiles. In addition, a tile being rectangular, the fitting areas 10 of the upper part 7 reduce the surface visible from this top 7; well, when several tiles are placed on a roof, and even if they are rectangular and are arranged one behind the other as shown in figure 2, a the angles of each tile correspond not four tiles adjacent, but only three adjacent tiles. Thus, they are reduced the overlays of one tile in another and, consequently, They also reduce infiltration problems.

The tightness is also improved due to that the areas of union are usually made between three Texas instead of four tiles.

The top 7 and bottom 8 of tile 1 they can be flat, as illustrated in figures 1 or 2.

The top 7 and bottom 8 of tile 1 they can comprise at least one concavity 13 open upwards which defines at least one corresponding channel 13 whose axis is oriented according to the slope of the roof, as illustrated in the figure 6.

Alternatively, but similarly, while maintaining a generally flat tile plane, the parts  upper 7 and lower 8 of tile 1 may comprise a series of grooves and / or ribs whose axes are oriented according to the slope from the roof.

According to the invention, the width of the part lower 8 of the tile is greater than the width of the upper part 7, as depicted in figures 4, 5, 7 and 8.

Thus, the tile according to the invention represented in Figure 4 comprises a lower part 8 of width greater than the of the upper part 7. In addition, a nerve 14 of purpose essentially aesthetic is arranged along the longitudinal axis of the tile, in the middle part of the lower part 8, so that the upper surface 6 of the tile, once placed makes three tiles appear instead of just one, as shown in the Figure 5. As explained above, such a structure of tile allows to cover the same given surface with three times less of tile than with the tiles known in the prior art. So, the placement and disassembly are easier and therefore need less labor and are less expensive. Finally for a given roof surface, fewer tiles are needed to perform the roof and so there are less overlays between tiles and, therefore, there are fewer infiltration risks.

According to an alternative of the invention, the upper 7 and lower 8 of tile 1 are flat as illustrated in figures 4, 5 or 7. As depicted in figure 7, the side edges 4 of the bottom 8 of the tile can understand then some arches 15 whose convexity is directed towards the upper part of the tile and whose axis is confused with the axis longitudinal of the tile. These bows 15 play the role of parts covering 11 of the lateral fitting areas of the parts upper roof tiles adjacent to the lower row.

According to another alternative -not represented- of the invention, the upper 7 and lower parts 8 of the tile comprises a concavity 13 open upwardly defining a channel 13 whose axis is oriented according to the slope of the roof. Similarly to the alternative described above, the bottom 8 can understand then, along its lateral edges 4, about arches 15 whose convexity is directed towards the upper part of the tile and whose axis is confused with the longitudinal axis of the tile, as It is represented in figure 8.

In all embodiments of the invention described above, the angle of inclination of the tile 1, when placed on the roof, is comprised of preference between 7º and 70º with respect to the horizontal.

It follows from the foregoing that anyone who be the preferred embodiment of the present invention, three of the four edges of the tile are always covered by tiles adjacent and the side edges are coated in at least the half its length. Thus, the stability of the tile is increased and its resistance to wind start, particularly when it is rotating or blowing against the slope of the roof, since that no angle of the tile is common to two edges not coated.

In addition to its excellent capabilities for resist starting by the wind, the tile according to the present invention allows to effectively prevent water infiltration, particularly when the rains are accompanied by a strong wind lateral or against the slope of the roof.
