ASEISMATIC REINFORCING STRUCTURE AND ASEISMATIC REINFORCING METHOD FOR WALL TYPE RC STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an aseismatic reinforcing structure and an aseismatic reinforcing method for a wall type RC structure capable of attaining aseismatic reinforcement for the wall type RC structure easily, quickly and reliably by concurrently using a reinforcing steel sheet winding method using mechanical rolled joints and high-tension rods via the boring of the wall type RC structure by ultrahigh-pressure water injection. ;SOLUTION: Joint sections 49, 40 provided on the side edge sections of reinforcing steel sheets 18-35 and having first and second coupling lugs 51, 54 and first and second coupling grooves 52, 53 on overlap faces are overlapped together and fastened by fastening means 55, 56 to form cylindrical reinforcing walls 15-17 around a wall type RC structure 10. Multiple high-tension rods 42 are inserted into multiple through holes 41 formed in the thickness direction by ultrahigh-pressure jet water injection on the wall type RC structure 10, and both ends of the high-tension rods 42 are fastened.;COPYRIGHT: (C)2000,JPO
