By installing a large reinforced concrete wall that was restored from on-site construction on the lower floors of the side of the new high-rise building, there is no joint and the landscape before restoration is well preserved.

Further, since the upper and lower ends of the wall body are supported by the deformation follow-up type support mechanism against horizontal force, the wall body follows the deformation of the new high-rise building against a large horizontal force at the time of an earthquake or the like. The generation of cracks is prevented.

[0010]

The present invention will be described below with reference to the illustrated embodiments. A is a large reinforced concrete wall that has been restored from on-site construction, and is constructed with stone or bricks, is a new high-rise building with a steel frame structure, and is installed on the lower floors of the side surface of B, for example, the 1st to 3rd floors. The upper and lower ends are supported by the high-rise building B by upper fasteners a and lower fasteners b at four or more places respectively.

FIG. 2 shows a conceptual diagram of the above structure. The lower fastener b supports the weight of the wall B, supports the pins horizontally in the out-of-plane horizontal direction, and has a proportion in which the wall does not float up in the in-plane horizontal direction. It is fixedly supported by this.
Further, the upper fastener a is configured to freely displace the wall body in the vertical direction and the in-plane horizontal direction, and to support the wall body in the out-of-plane horizontal direction.

Therefore, according to the above-described embodiment, the wall A follows the deformation of the high-rise building B due to a large horizontal force such as an earthquake, and the wall body A does not crack. 3 and 4
Indicates an upper fastener a made of casting, and a pull-out preventing leg piece 2 projecting from a horizontal anchor metal 1 is fixed to the concrete of the wall A, and a long slot 3 extending in the in-plane horizontal direction.
