ANCHORING SYSTEM FOR ANCHORING VERGE TILES AND/OR RIDGE TILES

Abstract: An anchoring system for anchoring verge tiles and/or ridge tiles consists of a rail (4) to be fixed to a roof verge or roof ridge, a number of essentially U-shaped clamping elements (3) which can be slidably accommodated in said rail and a projecting rib (2) provided on the underside of each verge tile (1) or ridge tile (14), which rib (2) can be clamped in one of the said clamping elements (3).

Description: Anchoring system for anchoring verge tiles and/or ridge tiles The invention relates to an anchoring system for anchoring verge tiles and/or ridge tiles. Verge tiles and ridge tiles are at greater risk of being blown off the roof in a storm than are ordinary roof tiles which are joined to one another and to the roof battens by so-called tile clips. The aim of the invention is to substantially reduce this risk and to provide an anchoring system by means of which verge tiles and ridge tiles can be firmly fixed to the roof. Another aim is to design such an anchoring system such that verge tiles and ridge tiles can very easily be brought into the anchored position. According to the invention the anchoring system is to this end characterised in that it comprises the following components: a rail to be fixed to a roof verge or roof ridge, a number of essentially U-shaped clamping elements which can be slidably accommodated in said rail and a projecting rib provided on the underside of each verge tile or ridge tile, which rib can be clamped in one of the said clamping elements. In order to be able to improve the clamping and anchoring the arms of the clamping elements can be angled towards one another in a V-shape and provided with at least one barb. The invention also relates to a building construction, the pitched roof of which is provided, close to a sloping verge thereof, with verge tiles which are anchored using the system according to the invention. The arms of the rail preferably have end pieces angled towards one another and the rail is fixed to a roof batten by means of strips or sections, which strips or sections have a trapped part located between the arm end pieces angled towards one another. The invention also relates to a building construction, the pitched roof of which is provided with ridge tiles which are anchored using the system according to the invention. The rail of this anchoring system can be fixed to the ridge board of the roof ridge or fitted as a replacement for the ridge board of the roof ridge. It is pointed out that from French Patent Application 2 756 308 it is known per se to clamp ordinary roof tiles which have a projecting rib on the underside in a U-shaped clamping element. However, the clamping elements are not slidably mounted in a rail. Furthermore, German Patent Application 2 622 056 shows a roof ridge where ridge tiles are fixed in place by means of a row of clamps, which are slidable on a rail. However, the ridge tiles do not have moulded-on ribs, on their underside, which can be clamped in U- shaped clamping elements. The invention will now be explained in more detail with reference to the figures. Figure 1 shows a perspective view of a pitched roof, on a sloping verge of which a verge tile has been anchored by means of the anchoring system according to the invention, part of the verge tile being imagined as broken away. Figure 2 shows a cross-section through the ridge of a pitched roof with a ridge tile anchored in accordance with an anchoring system according to the invention. Figure 3 shows a cross-section through the ridge of a pitched roof with a somewhat modified embodiment of said anchoring system. Figure 4 shows a perspective view of an essentially U-shaped clamping element of the anchoring system according to the invention. Figure 1 shows a verge tile 1 which is known per se and is provided with a moulded-on rib 2 on the underside. The verge tile is located on the sloping verge of a pitched roof. The said rib 2 has been pushed into an essentially U-shaped clamping element 3. As Figure 4 shows the arms of this clamping element are angled towards one another in a V -shape and on pushing the verge tile rib 2 into the clamping element 3 are pushed apart, as a result of which the verge tile is firmly clamped. The clamping element 3 is slidably accommodated in a rail 4 by means of its bottom portion, which rail 4 is joined to a roof batten 6 by means of an L-shaped section 7. The section 7 has a portion 8 that extends into the rail and is provided with two slots into which end pieces 9a, which are angled towards one another, of the arms 9 of the U-shaped rail 4 project. The section 7 is firmly screwed to the roof batten 6 at 10. The roof batten 6, in turn, is nailed or screwed to the counter-battens, one of which (11) is shown. The counter-battens 11 are fixed in a manner known per se to the roof boarding, which is not shown. Each of the arms of the U-shaped clamping elements 3 is provided at its top with an oblique barb 12. These barbs 12 can engage in the rib 2 and thus form an extra facility for preventing the verge tiles blowing off the roof. The verge tile shown is, of course, one of a row of overlapping verge tiles which have each been anchored in the same way. In the case of application of the anchoring construction for anchoring a ridge tile 14, as is shown in Figures 2 and 3, essentially the same anchoring system is used, consisting of a rib 2 which projects from the underside of the ridge tile 14 and is inserted in an essentially U- shaped clamping element 3 which is slidably accommodated in a rail 4 by means of its bottom portion. In the embodiment according to Figure 2, the rail 4 has been screwed onto the ridge board 16 of the roof ridge construction. With this arrangement the ridge board 16 is located between the plates 17 of the roof ridge construction. In the embodiment according to Figure 3 the rail 4 replaces the ridge board. The rail 4 can also be integrated with the plates 17 of the roof construction. In Figures 2 and 3 the upper ordinary roof tiles are indicated by 18, the upper roof battens by 19 and the upper sections of the roof boarding by 20. In addition to the advantage of an exceptionally high resistance to storms, the anchoring system with ribs 2, clamping elements 3 and rail 4, which has been described, also has the advantage that anchoring of the verge tiles or ridge tiles can be carried out quickly and efficiently.
