CONSTITUTION:In ridge material 2, one end 2B1 of a downward inclined part 2B inclined at the flow pitch of a triangular roof part C2 is rigidly fixed to one end of an ridge part 2A formed of shape steel and passing a main ridge A. This ridge material 2 is erected by outer bundle material 7, 7 disposed at both ends of joint material 6 bolt-fastened to the other end 2B2 of the inclined part 2B, and inner bundle material 9 disposed at the other end 2A2 of the ridge part 2A. Fitting pieces 3, 3 for bolt-fastening up-beam material 4, 4 extended to the outer bundle material 7, 7 along down-ridge B, B are previously provided at one end 2B1 and both side faces of the inclined part 2B.</p> |
