Summary:PROBLEM TO BE SOLVED: To increase bearing force of a beam-to-beam joint part so as to be able to construct a large structure, and reduce the number of beams to be used so as to increase the freedom of a plan and to reduce cost by arranging dowel washers provided with biting claws at the time of fixing the end part of one beam to a joint hardware bolt-fixed to the side face of the other beam. SOLUTION: In a joint part where the end part of a beam is fixed to a joint hardware 5 bolt-fixed to the side face of a girder 1, dowel washers 15 provided with claws biting into the peripheral parts of bolt holes 18 of the girder 1 are arranged between the side face of the girder 1 and the joint hardware 5. The outer face of a contact part 6 of the joint hardware 5 is brought into contact with the side face of the girder 1 from the outside of the dowel washers 15, 15, and the bolt holes 18 of the girder 1 and bolt holes of the joint hardware 5 are made coincide with each other and positioned. A nut 28 is screwed with a bolt 21 inserted in the bolt hole 18 to fix the joint hardware 5 to the girder 1. With this fastening, the dowel washer 15 is held with the claw biting deep into the peripheral part of the bolt hole 18.
