Description

7802814-9 The most common type of staple today is the fourth type, listed above, other types have not been satisfactory for various reasons. Thus, it has often happened that sheet metal roofs have blown off due to the sliding clamps being unhooked or otherwise loosened. either at the breathing seam or at the connection of the sliding part to the anchoring plate.

For example, the following errors occurred on the first mentioned of the above types.

The sliding part at this is folded 180 degrees along one of its edges and is hooked in a corresponding fold of 180 degrees in the upright part of the anchoring plate bent at 90 degrees, the other part of which is anchored in the base.

The sliding part is usually folded at the upright seam of the plate. In the case of large suction forces and in the case of a longitudinal pulsation of the seam, it can happen that the plate 'detaches from' the substrate by hooking the sliding part out of the anchoring plate. This occurs even if the seam is folded outwards downwards and then straightened again, which can occur due to, for example, carelessness during assembly.

Sliding clamps with metal wire have now practically been withdrawn from the market, as they are considered to be too space-consuming and too expensive. The technical quality is also degraded due to the coarse wire, which exerts a certain wear on the plate.

The object of the present invention is to provide a sliding clamp intended for cladding sheet, which does not suffer from the above-mentioned disadvantages of known sliding clamps, and in addition is material-saving.

The sliding clamp according to the invention is characterized in that the anchoring member in the second, relatively first part angled part is provided with said enclosed slot, which extends along a substantial part of said second part, and that the lower hook of the sliding part is placed in said slot and runs therein. and extends over the upper edge of the second part with its legs, which are mutually fixed, suitably welded together.

By one end of the sliding part gripping the corresponding edge of the anchoring member or plate and then welding the lower part of the Vif sliding part, a certain movement perpendicular to the plate surface between the anchoring plate and the sliding part and thus between plate and base without any risk of the sliding part being unhooked , as is the case with the previously mentioned, now common staples. The invention is described in detail in the following with reference to the accompanying drawings, in which two embodiments of the invention are schematically illustrated by way of example. 7802814-9 §ig¿_1 shows an embodiment of the invention, where the fastening base for the bracket lies directly under the cladding or surface plate, and §ig¿_g shows an embodiment, where an insulating layer is present between the surface plate and the fastening base. Corresponding parts have been provided with the same reference numerals in the two figures.

The sliding clamp according to Fig. 1 consists of an anchoring plate 1 and a sliding part 2 bent in 180 degrees. One angle leg of the sliding part is attached to the upwardly folded seam of the plate 12, while the other angle leg is bent and welded at 6 around the anchoring plate 1. The anchoring plate 1 has holes 5 for attaching the sheet metal to the base 13 and a slot 4 for passing the sliding part. The folding 3 of the tin bent upwards at 90 degrees also contributes to better slidability, which also stiffens the tin.

The anchoring plate 1 is screwed or nailed to the base 13 and the sliding part 2 is fastened by folding 7 to the folded-up seam of the plate 8 after it has been mounted and before the next plate 9 is applied to the roof. Of course, methods other than folding can be used for attaching the sliding part to the plate 8. It can thus, for example, be welded to the stand seam 10. Since the staple is attached to the plate and substrate in this way, the next plate 9 is laid on the substrate so that it covers the staple. The upwardly folded fold of the plate 9, which is laid against the fold of the plate 8, is higher than the latter and is folded, at the same time as the folds are folded at each other, over the fold of the plate 8. The seam is illustrated at 11.

The buckling of the anchor plate 1 bent upwards by 90 degrees can vary in height depending on the fact that different attachment levels may be required.
