Description

  The present invention relates to a fixing bracket for fixing a folded roof material to a roof base material, and in particular, to a fixing bracket fastened and fixed to the roof base material.

  When renovating the existing slate roof, a method of spreading the folding roof material on the outer surface of the slate roof (see Patent Document 1), a method of removing all the slate roofing material, and newly spreading the folding roof material There is. In the former, the roof structure is complicated because an existing hook bolt is used to construct a roof base for the folding roof material on the outer surface of the slate roof. In many cases, the slate roofing material is fastened and fixed by hook bolts that are hooked on the roof base. Therefore, in the latter construction method, after removing the slate roof material and the hook bolt, it is necessary to newly fix the tight frame to the roof base. The tight frame is fixed by welding to the roof base or by bolt fastening.

  The fixing metal fitting of the present invention is fastened and fixed to the roof base material with bolts. However, it is known in Patent Document 2 that the metal fitting for assembling the folded roofing material is fastened and fixed to the roof base material with bolts. It is.

  When welding the tight frame to the roof base, it is inevitable that spatter will scatter and fall. Moreover, when fixing a tight frame to a roof base | substrate by bolt fastening, when forming a bolt penetration hole in a roof base | substrate with a drill, it is inevitable that chips will fly and fall. In any case, there is a possibility that mechanical equipment and products installed indoors may be damaged by the spatter and chips scattered. In order to prevent scratches due to such spattering, it is only necessary to protect indoor machinery and products, but this requires additional labor and cost for roof repair. Since the tight frame welding work can only be done manually, the work results tend to vary, and it is difficult to obtain a stable roof strength. In addition, as represented by the indoor heated pool roof, in a hot and humid environment, when the tight frame is welded, the paint applied to the roof base material burns away, so the welded part is easily rusted and rust-proof. Extra cost is required.

  The object of the present invention is to fix the fixing bracket for spreading the folded roofing material to the roof base material without causing spatter and chips, and thus has an influence on the machinery and equipment installed indoors. In addition, the present invention is to provide a fixing member for an engraved roof material that can be used for repair work of a slate roof, construction work of an engraved roof, or the like. An object of the present invention is to provide a fixing member for an engraved roof material that can be used to replace a roof by using an existing roof base material as it is.

  The fixing member for the folding roof material according to the present invention includes a first metal member 6 fastened and fixed to a roof base material 1 having a support wall 3 on the upper surface and a mounting wall 4 that is bent downward continuously from the support wall 3.
