OPENING SECTION EARTHQUAKE RESISTANT REINFORCING STRUCTURE AND OPENING SECTION EARTHQUAKE RESISTANT REINFORCING METHOD

PROBLEM TO BE SOLVED: To increase construction efficiency of an earthquake resistant reinforcing technique of the constitution making use of an anchor bolt for the circumferential edge material of an opening section. SOLUTION: A reinforced concrete beam 10a forming the opening section 30 and a bolt 40a planted in a reinforced concrete column 20a fasten a nut 42 to the bolt 40a in a state to make them pass through a frame material 50a forming a frame body 50 to connect the frame body 50 to the bolt 40a with a direct attaching means. A spiral hoop is placed between the anchor bolt and a stud by adopting such a constitution, and labor, etc. necessary to form a form for injecting mortar to such a part can be saved, and the construction efficiency of earthquake resistant reinforcing construction work having the frame body 50 for earthquake resisting reinforcement providing a brace 52a to the opening section 30 can be increased.
