Description

  The present invention relates to a fixture for fixing a folded-plate roof material suitable for fixing a folded-plate roof material widely used in a large-area roof such as a factory, a warehouse, or a large store. In addition, the fixing bracket for the folded-plate roof material of the present invention can be used only when a new folded-plate roof material is installed on the existing folded-plate roof material and the roof is repaired (double-folded folded-plate roof). It is also used when a folded-plate roofing material is installed on a tight frame and the roof is lifted (newly installed). Hereinafter, a new folded-plate roofing material is installed on the existing folded-plate roofing material. The case where the roof is repaired will be described as an example.

  Folded roofing materials are originally made of steel sheet coils, which are formed into a desired shape and length using a roll forming machine installed at the manufacturing plant and the operation site, and used as roofing materials as they are. Therefore, it is widely used as a roofing material that can economically secure workability, wind pressure strength, and waterstop.

  In particular, in recent years, this type of roofing material has been widely used as a roofing material for the so-called cover construction method, in which a new folded-plate roofing material is placed on an existing folded-plate roofing material and the folded-up roof is lifted up. This has enabled efficient refurbishment of folded-plate roofs.

  As a prior art in this regard, the neck portion of the clap portion of the existing folded plate roofing material is clamped by a pair of clamping pieces, and is connected to a hanging element fixed to the clamping piece or the clamping piece. A metal folded-plate roof as disclosed in Patent Document 1, for example, can be raised by associating a new folded-plate roof material with a hanging member fixed to the upper support portion. Replacement fittings are known.
