<P>PROBLEM TO BE SOLVED: To provide a reinforcement structure for suppressing the widening of a crack generated at the peripheral edge part of an additional skeleton and preventing the decline of the effective strength of the concrete of the additional skeleton. <P>SOLUTION: The reinforcement structure includes an existing skeleton 10 and an additional wall 20 additionally placed to the existing skeleton 10. A vertical reinforcement 21 and a horizontal reinforcement 22 of the additional wall 20 include a reinforcement bar body 40 which is extended linearly, and a fixing part and a fixing mechanism 41 provided on both end sides of the reinforcement bar body 40 and fixed to the peripheral edge part of the additional wall 20. Since the concrete at the peripheral edge part of the additional wall 20 is restrained by the fixing part and the fixing mechanism 41, even when a crack is generated at the peripheral edge part of the additional wall 20 in an earthquake, the widening of the crack is suppressed. Thus, the decline of the effective strength of the concrete near the crack and the decline of integration with the existing skeleton 10 and reinforcement bearing force can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
