効果が得られる。In the case of the RC column coated with a reinforced steel plate of the present invention,
The compressive strength of the concrete on the RC column 2 is increased by the confined effect due to the restraint of the reinforcing steel plate 1, and therefore, the strength of the covering concrete 13 is also similar to that of the core concrete 12 even after compression yielding.
It does not drop sharply. Furthermore, reinforcing steel sheet 1
Upper and lower edges, upper beam 3 and lower beam 4
And the gaps 5 and 6 are provided between
Is not transmitted to the reinforcing steel plate 1, so that the axial rigidity and the bending rigidity of the reinforcing steel plate 1 are substantially equal to those of the internal RC column 2. In addition, by appropriately securing the sizes of the gaps 5 and 6, the reinforcing steel plate 1 does not contact the upper beam 3 and the lower beam 4 even when the building structure 18 is largely deformed. The above-described effects can be obtained.

できる。According to the present invention, a tubular reinforcing steel plate 1 is disposed at intervals on the entire peripheral surface of an RC column 2, and the upper and lower edges of the reinforcing steel plate 1, Gaps 5 and 6 are provided between the lower edge of the lower beam 3 and the upper edge of the lower beam 4, and a time-hardening filler made of cement paste or mortar between the reinforcing steel plate 1 and the RC column 2 17, the periphery of the RC column 2 is constrained by the reinforcing steel plate 1 attached so as to surround the entire periphery of the RC column 2 via the time-curable filler 17, and the occurrence of the confined effect, etc. Thereby, the axial strength and the shear strength of the RC column 2 can be increased,
In addition, a large earthquake occurs due to gaps 5 and 6 between the upper edge and the lower edge of the reinforcing steel plate 1 and the lower edge of the upper beam 3 and the upper edge of the lower beam 4 in combination with the above configuration. Then, even if the building structure 18 rolls greatly, there is no danger that the upper beam 3 and the lower beam 4 will be damaged by the upper edge and the lower edge of the reinforcing steel plate 1. Is not transmitted, and the axial rigidity and bending rigidity of the reinforcing steel plate 1 do not change.
This can be easily performed in the same manner as in the case of the ordinary RC column 2.
