Description

Technical field

The present invention relates to the fastening and sealing of tiles, preferably flat tiles, on a roof structure. The invention will be partially described by the example of flat tiles, but is not limited to this. Used in the description and formula, the term "tile" should be understood as a roof tile, roof tile, slate, flat tile of lumber or other material or any similar roofing material.

State of the art

Various roofing systems for attaching flat roof tiles to a roof are known.

Australian patent N672286 describes a roofing system with a tile in which parallel connecting rails spaced apart from each other are located between two adjacent battens, and each tile is supported by its opposite edges on adjacent battens. In this patent, the fastening means fixing the lower end of the corresponding tile from the rise, made in one piece with the rail. Such slats, known as "slat rails", are used to prevent the passage between tiles and moisture, dust, etc. from entering the attic. Two types of fasteners are described. In one embodiment, at the lower end of each slat rail there are legs made with it in one piece and bent around the lower edge of the corresponding tile. In the second embodiment, each slat rail has a hook located in its center and protruding upward to engage the lower end of the tile located in the next row, which is upper relative to the slat rail, in order to prevent the tile from rising.

GB 2160559 describes a slat rail having an element similar to a protruding hook that engages with the lower end of a tile located in the next upper row relative to the slat rail. This design is virtually identical to the design described in Australian patent N672286.

DE 800784 describes a slat rail extending between the upper and lower battens, the lower end of the slat rail having tabs that engage with the lower end portion of the corresponding tile.

In these documents, devices in the form of various paws or hooks are used to hold the lower end of the corresponding tile and prevent it from rising, for example, in strong winds, etc.

However, in practice, it turned out that in constructions using the system described, for example, in Australian patent N672286, good weather resistance is not achieved and problems arise due to corrosion of the part of the railing which is bent or extends beyond the lower end of the tile.

It would be desirable to have an alternative retention system for fixing tiles, especially flat tiles, where there are no problems associated with corrosion.

SUMMARY OF THE INVENTION

Therefore, in one embodiment of the invention, which is not the only or all-encompassing one, a slat rail is designed to support roof tiles and be installed between adjacent battens with support on them, and each slat rail is of such length that when installed on the roof its lower end the part stands for the lower of the neighboring battens, as a result of which each tile rests with its opposite edges on adjacent underbody battens; the upper surface of each specified lath is in contact with the neighboring edges of adjacent tiles adjacent to each other by the edges, and serves as a support for them; wherein the rake rail includes a tile holding means designed to prevent it from rising and comprising a wire clip coupled to the rake rail and having at least one leg with a hook bent portion for engaging with the lower end of the tile when installed on the roof.

Preferably, the wire clamp wire was made of an elastic material. Preferably, the wire is made of stainless steel.

In one embodiment, the holding means may comprise a substantially U-shaped wire body having legs that, when mounted on the roof, are substantially parallel to each other, and an eye that extends laterally from each leg for placement in an opening in the side flange of the battens, the leg ends with a hooked part. When the retaining means are made, the legs can be diverging, but they must be resilient so that when installing the racks on the roof, each eye is fixed in the corresponding hole.

The slat rail may have at least two longitudinal strips of sealing material designed to create a seal under the respective sides of adjacent tiles. The slat rail may also have a wider central longitudinal sealing strip. The lateral edges of adjacent tiles can rest on this wide central longitudinal sealing strip.

The slat rail may also have longitudinally extending grooves formed on its upper surface, which facilitate the flow of water. These grooves may be between two longitudinal stripes and a wider central longitudinal longitudinal sealing strip.

In the case when the slat rail is to be used with laths of lumber, it can have side legs that, when installed on the roof, are adjacent to the lower lath, for fastening the slat rail to the wooden lath with nails or screws, and the upper foot for fastening the lath rail with nails to the upper from the neighboring battens.

If the slat plate is to be used with metal sheathing, it may include a means of engaging with the lower of adjacent sheathing, comprising an installation groove located near the bottom surface of the sheathing rail and its lower end and open toward that lower end, so that the upper shelf of the lower of the neighboring sheathing when installing the roof racks, it enters this installation groove. The upper end of the slat rail may rest on the lower shelf of the upper of the adjacent battens.

The slat rail may have a foot extending downward at its upper end, which, when mounted on the roof, engages with the corrugation of the lower shelf of the supporting battens.

In addition, the slat rail may have lateral shelves extending downward, which are bent outward at a slight angle, which makes it possible to stack the underbody rails.

The hook-curved part can be adapted to accommodate and hold tiles of different thicknesses due to the essentially U-shaped clamping part at the second end, such that the lower edge of the tile enters this U-shaped part, and the U-shaped clamp part is resilient relies on the top surface of the tiles.

The invention will now be described in more detail with reference to the accompanying drawings, in which a preferred embodiment is illustrated.

The terms "upper" and "lower" in the description and claims are used in relation to the position of the rails and the clamp, which they have when installed on an inclined roof.

The slat rail, indicated generally by 10, has an upper surface 12, side flanges 14 extending downward and an upper end tab 16 located at that end of the slat rail, which when used, i.e. when installed on the roof, occupies the upper position. On the upper surface 12 there are two grooves 18 and a peripheral sealing strip 20, which extends along each side of the strip and is bent at the top to form an arcuate portion 22. There is also a central sealing strip 24, wider than the side sealing stripes 20. Two longitudinal stripes sealing material designed to create a seal under the respective sides of adjacent tiles. The lateral edges of adjacent tiles can be supported by a wider central longitudinal sealing strip.

The side shelves 14, located on each side of the racks, end, not reaching its lower end, and where these shelves end, there is a groove 26, open towards the lower end of the racks and when used interlocked with a shelf of battens 50, as will be described in more detail when considering figure 4.

A clip 30 for holding the tiles located below it is installed on the slatting rail 10, shown in more detail in FIGS. 5 and 6. This clip is generally U-shaped and includes an upper end 32 and legs 34 and 36 on which the ears 38 are made. When installing the clamp 30 in the rails, these ears 38 enter the holes 40 made in its side shelves 14 to hold it in place. As can be seen in FIGS. 5 and 6, the legs 34 and 36 diverge, but since the clamp is made of elastic wire, they can be moved so that the ears fall into the holes 40, while the legs become essentially parallel to each other, and due to the elasticity of the wire the ears 38 are held in the holes 40.

Each leg 34 and 36 ends with a hook portion bent 42, located at right angles to the common plane of the holding clamp.

In figure 4, depicting the assembly, it is clear that the battens 50 is Z-shaped and consists of a vertical wall 51 with an upper shelf 52 and a lower shelf 53 extending in opposite directions. The lower shelf 53 is preferably grooved in the longitudinal direction. The end of the upper flange 52 fits into a groove 26 at the end of the lateral flange 14 of the racks. The tile 54 lies on the slat rail 10, being in contact with the sealing strip 20, providing a seal on the lateral edge of the tile. The hooked portion 42 of the holding clip 30 extends beyond the tile 54 and contacts its upper surface, preventing the tile from slipping. The specified part 42 is quite elastic and therefore it can include tiles of different thicknesses, although if it is intended to use a significantly thicker tile, the retaining clips 30 may have parts of various sizes bent in the form of a hook. The thickness of the tile can be in the range of 3 to 12 mm, so that one holding clip can be provided in which the part bent in the form of a hook has a pharynx corresponding to the tile 3-7 mm thick, and another holding clip in which this part has the pharynx corresponding to a tile 8-12 mm thick.

It should be noted that to facilitate the replacement of the holding clip, it is advisable to have a guide groove, as shown by arrow 56, between the upper shelf 52 of the Z-shaped battens 50 and the lower side of the rails 10 so that it is relatively easy to push the new holding clip with the ears 38 in the holes 40. If the battens are made of lumber, there will still be a gap through which a holding clip can be inserted so that the ears enter the holes 40 on the sides of the battens.

The invention has many advantages compared with known technical solutions. As indicated above, in the known technical solutions, the tabs for holding the tiles are made on the slat rail and are its integral part. The slat rail and tabs are made of mild steel, and therefore, so that the tabs are strong enough, they must have an appropriate width.

A particular advantage of the elastic holding clip according to the invention is that it can be removed without removing the entire slat rail by sliding the hook sections 42 of the legs so that the ears 38 extend out of the holes 40 on the sides of the slat rail, after which completely remove the holding clip, which will remove the tiles.

The wire clip is attached to the slat rail in a place remote from the corrosive atmosphere and, thus, from the condensation area, and reaches the end of the tile.

The shape of the wire can be easily changed to hold the tiles of various shapes without the need to produce another slat rail, which is economically viable.

If you want to remove only one tile, then you need to move only one of the two bent in the form of a hook parts 42 on each of the two adjacent rails, and release the tile.

The wire clip is not very visible on the roof, while the paws attached to the battens are relatively visible, even if they are painted or coated with a coating similar to the surface of a tile. Therefore, when using shingles of different colors, body rails have to be replaced, while when using a wire clip, there is no need to replace slats. In addition, in the case of replacing the tile, bending the legs to release the tiles and then bending them to secure the new tile can lead to cracking of the paint or coating on the legs.

Further, in the climatic zones where snow falls, when the snow leaves the roof, the legs can bend down and stop holding the tiles. When using a wire clamp, a small area confronts the snow sliding along the roof, and the stiffness of the stainless steel wire clamp prevents it from bending.

It should be noted that to facilitate the replacement of the holding clip, it is advisable to have a guide groove, as shown by arrow 56, between the upper shelf 52 of the Z-shaped battens 50 and the lower side of the rails 10 so that it is relatively easy to push the new holding clip with the ears 38 in the holes 40. If the battens are made of lumber, there will still be a gap through which a holding clip can be inserted so that the ears enter the holes 40 on the sides of the battens.

Since the clamp is preferably made of stainless steel, it will not corrode in the atmosphere and, therefore, rusty stripes will not appear on the tile. Due to the fact that the wire has a relatively small diameter, it will not be visible on the roof and the roof surface will appear more even. The wire clip will also not be an obstacle that traps moisture and debris on the roof, unlike the wider legs.

Various examples have been presented in the description, however, the invention is not limited to any of them and may include two or more examples combined together. The examples serve only to illustrate the invention and do not limit it.

In the description and claims, the words “includes” and contains, as well as “including” and “comprising” mean, unless the context indicates otherwise, the presence of an element or group of elements indicated after these words, not excluding the possibility of any other element or another group of elements.
