Description

  The present invention relates to an architectural support that can be easily and quickly attached to a fastening connection portion of a tightening type lower roof in a two-layer roof and can be attached extremely firmly to the lower roof.

  Conventionally, there are many enclosures such as a two-layer roof or a wall composed of a lower roof and an upper roof. These enclosures include a newly-installed two-layer roof (or wall) and a modified roof in which a new roof (or wall) is newly installed on the existing roof (or wall). The lower roof (or wall) is constructed by a metal folded plate construction board. In this type of enclosure, there is a building board in which a lower eaves part and an upper eaves part are formed, so that the lower eaves part and the upper eaves part of the adjacent building boards are wound together. In some cases, the plate members for construction are connected to each other while forming the fastening connection portion.

  In order to construct the upper roof (or wall) on the lower roof (or wall), a receiving metal fitting is installed on the lower roof (or wall). In particular, if the lower roof (or wall) is of a clamped type, the bracket is fixed to the lower roof (or wall) using the clamped connecting portion. Many of the metal fittings that are fixed using this type of tightening connection portion are of a type that is fixed in a state in which the tightening connection portion is sandwiched. Specifically, as shown in Patent Document 1, there are many ones mainly composed of two members separated into left and right.
