For example, when repairing or refurbishing roofs and outer walls that have been rolled up with slate corrugated sheets or folded plates, the existing roofing materials and outer wall materials must be stacked without overlapping existing roofing materials or outer wall materials. Tensioning is done.
Various fixing methods using a protruding portion from the top surface of the roof material of the hook bolt for fixing the existing roof material have been proposed for fixing the roof material for laying on the existing roof.

However, this hook bolt is often rusted or damaged over time, and is not screwed, and cannot be reused as it is for fixing roofing materials.
Therefore, in Patent Document 1 below, the bolts are placed on the hook bolts fixing the existing roof with the head facing down, and both the bolts are inserted into a metal pipe, and the inserted metal A bolt connection method is disclosed in which both bolts are connected by crimping a pipe made by a nut and a head portion of both bolts.

However, in the above bolt connection method, a metal pipe is crimped to the nut or head of the bolt in a hexagon, and therefore, a dedicated bolt connector with a hexagonal shape between the pressing portion and the arm portion is hydraulic or pneumatic. When a large area is to be constructed, it is necessary to work by lifting such dedicated bolt connectors on the roof to improve work efficiency.
