Abstract

To simplify the assembly of facing panels (18) designed on the groove/spring principle, a fastening device has hooks (16) each of which engages between groove (20) and spring (22). The hooks are placed at predetermined distances equal to the width of the facing panels on metal or plastic assembly rails or plates (12). An insulating panel (14) can be permanently mounted on the rear face of the assembly panel (12).[EP0535011A1]

Description

Description of the invention The invention relates to a mounting device for covering plates such as profile boards, panelings and the like, based on the tongue and groove principle.

Such covering plates are frequently used in attics below or in between rafters. For mounting the covering plates or the profile boards, z-shaped, bent hooks made from sheet metal are known, which after mounting the profile boards are generally fastened with nails to the rafters or the slat construction such that they engage in the grooves of the profile boards without obstructing the insertion of the tongue in the groove of the next board.

The mounting of the profile boards by means of the mounting hooks is, however, rather laborious, because the hooks have to be individually positioned and fastened with nails. To simplify the mounting procedure DE-GM 82 29 239 suggests to form the hooks with suitable spacings in one piece on an extended mounting rail. The mounting rails then replace part of the slat construction and the covering plates have only be wedged into the gaps in between the prefabricated hooks. The hooks are preferably punched directly from the sheet metal of the mounting rail and raised accordingly.

To improve the thermal insulation one generally inserts insulating panels made from mineral fibers, synthetic fibers or natural fibers into the gap between the roofing and the covering plates. The mounting of the insulating plates has so far generally been performed in a separate process before mounting the covering plates. Since the profile boards of the covering should not touch the insulating plates, one iA IE 911®52 has to provide a gap below the insulating plates for the slat construction which holds the covering. In this manner the available gap between the upper side of the insulating plates and the roofing is reduced which deteriorates the ventilation of the roof.

The invention has the goal to provide a mounting device for the above mentioned covering plates which allow a simpler and safer mounting of a thermally insulating covering. This goal is achieved with the mounting device of claim 1 according to the suggested invention, in which the hooks are formed in the covering surface of the extended mounting plate and where the insulating plates are firmly mounted on the backside of the mounting plate opposite to the hooks.

The mounting plates are preferably made from synthetic material or from thin zinc sheet metal, aluminum sheet metal or refined steel sheet metal which may be cut and delivered in the form of large plates or material sold by the metre and are properly cut directly on the building site. The thermally insulating plates and the mounting plates are combined in the manufacturing process to one thermally insulating and mounting plate such that the mounting of the thermally insulating and the covering plate may be done in one working cycle. Besides easing the work this solution has also the advantage that the thermally insulating layer is located directly on the side of the mounting plate which is turned away from the covering such that a smaller construction height is finally achieved and that the acoustic insulation is improved.

Further advantageous developments and designs of the invention axe mentioned in the subsections of the claims.

The hooks may be welded, riveted or glued to the IE 911852 mounting plate. In a prefered embodiment the hooks are formed by straps punched and raised out of the mounting plate. In. another embodiment the hooks are formed separately from the mounting plate and provided with clamping springs such that they may be wedged into corresponding openings of the mounting plate. In that case the openings may be placed, if necessary, shifted in several rows in a rather fine raster such that an adaptation to the covering plates of different widths is possible by arranging the hooks in the necessary spacings.

In the following, prefered embodiments of the invention are shown in the drawings.

Fig. 1 shows a cross section of the mounting plate with the attached thermally insulating plate.

Fig. 2 shows a section of the mounting plate seen from below according to Fig. 1.

Fig. 3 shows a cross section of the mounting plate according to a modified embodiment.

Fig. 4 shows a side view of a hook of the mounting plate according to Fig. 3.

Fig. 5 shows an outline of the hook according to Fig. 4.

Fig. 6 shows part of the mounting plate in a view from below according to Fig. 3.

In Figs. 1 and 2 a composite plate 10 is shown which is formed by a mounting plate 12 made from sheet metal of galvanized steel and a thermally insulating plate 14 which is connected over the whole area. In case of the thermally insulating plate one may have, for example, a plate of mineral fibers, polystyrol and the like, which are glued or laminated to the mounting plate 12. Out of the mounting plate 12 L-shaped hooks 16 are punched which project to the opposite side of the thermally insulating plate and which serve the mounting of the covering plates, profile boards and the like. In Fig. 1 the cross section of the covering plate 18 is indicated by a dash dotted line.

The hooks 16 are arranged in several parallel rows whose spacing corresponds to the width of the covering plates 18. As indicated in Fig. 1, the covering plates are attached to the hooks in a slightly tilted position so that one row of the hooks 16 insert into the grooves 20 of the covering plate. One side of the covering plate 18, which is furnished with the spring 22, is pushed against the mounting plate 12 from the position shown in Fig. 1 so that the shoulder, which is formed between the spring 22 and the main body of the covering plate, engages into the hooks of the next row. In this manner the covering plate IS is temporarily fixed on the mounting plate 12 and is finally held in position on the mounting plate after inserting the next covering plate. As indicated in Fig. 2, the hooks 16 have a triangular shaped tip 24 at their free end, which facilitate the insertion of the hook into the space between tongue and groove of the covering plate.

The composite plate 10 may be formed, for example, from an extended plate, whose width may be a multiple of the normal spacing between rafters. If the composite plate should be mounted below the rafters, the thermally insulating plate 14 is cut and removed according to the width between rafters such that the mounting plate 12 may be screwed or fastened with nails directly to the bottom of the rafters, while the remaining parts of the thermally insulating plates 14 fill the gap between the rafters. The screws or nails for fixing the mounting plate 12, are finally covered by the subsequent positioning of the cover plates 18.

Alternatively, the composite plate 10 may be manufactured in the factory already in slices, whose width is adjusted according to the spacing between rafters and where the mounting plate 12 extends beyond the thermally insulating plate 14 on its sides and form mounting flaps for attaching them to the rafters.

If the covering should only be mounted on the gaps between the rafters so that the rafters remain visible, then the composite plate may be fixed to the slats between the rafters analogous to the above mentioned procedure. In this case the mounting plate 12 may be tilted on its sides in such a manner that they form mounting flanges on the sides of the rafters.

Figs. 3 to 6 show a modified embodiment of a composite plate 10, where the hooks 16 are formed separately from the mounting plate. The mounting plate 12 provides in this case only mounting openings 26, which in turn serve for accepting one of the hooks 16 and which are limited on one side by a resilient tongue 28 which is slightly raised above the surface of the mounting plate. According to Figs. 4 and 5 every hook 18 has on its free end of the basisleg a pointed clamping spring 30 which is bent by 180° to the end of the spring, whose length is smaller than the length of the opening 26 of the mounting plate 12.

For mounting a hook 16 to the mounting plate 12 the hook is put directly on the surface of the mounting plate 12 and is shifted to the right in Figs. 3 and 6 so that the clamping spring 30 enters the opening 26 and takes hold of the tongue 28 which is protruding by a small amount. After further shifting the hook, the tongue 28 is elastically pressed back in the plane of the mounting plate 12 resulting in a firm clamp connection between the clamping spring 30, the tongue 28 and the base side of the hook.

Also in this embodiment the spacing between the openings 28 corresponds to the measure of the covering plate raster. If necessary, several series of mounting openings 26 may be formed on the mounting plate 12 whose spacing is adjusted to different rasters of the covering plates.
