Corrugated support frame fastening structure

摘要

[Problem] To provide a corrugated support frame fastening structure in which corrugated sheets have high fixing strength, rainwater does not enter factories and the like even during natural disasters such as typhoons, and corrugated sheets are not blown away even in strong winds. To do. A corrugated plate 10 in which a support member 20 is in contact with an outer surface and a steel structure 30 is in contact with a back surface, and a through hole penetrating the corrugated plate from an outer surface of the support member are inserted, In the corrugated plate support frame fastening structure including the tightening bolt 40 inserted through the steel structure, the cylindrical structure includes a plurality of locking members that form a strip shape and come into contact with each other to form a tubular shape. One end of the nut is gradually reduced in thickness and has an engaging portion 52, and the expansion nut 60 has a polygonal outer diameter, one end is gradually reduced in diameter, and one end having a smaller outer diameter is the regulating sleeve. The sealing member 70 has an annular shape and is disposed between the support member and the corrugated plate. The sealing member 70 has an annular shape and is inserted into one end of the cylindrical structure in the axial direction. [Selection] Figure 1
