摘要

PROBLEM TO BE SOLVED: To provide a technique for eliminating the need for welding work at a site even when a treatment at a rigid joint is required after assembling a steel frame at a construction site. SOLUTION: A roof receiving material 10 has an L-shaped angle shape and has two main body members 1 including a receiving portion 3 for roof receiving and a supporting portion 4 for fixing a set screw portion 2, and both main body members. It consists of one or more set screw portions 2 provided between 1 and 1, and has a substantially T-shaped cross-sectional shape in which the support portions 4 and 4 of both main body members 1 and 1 face each other with the set screw portion 2 interposed therebetween. The set screw portion 2 is composed of a set screw accommodating body and a set screw charged inside the set screw housing. [Selection diagram] Fig. 1
