DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall structure of a building in which outer walls of a plurality of buildings installed on independent foundations are connected to form a single building in appearance.

[0002]

2. Description of the Related Art Generally, a curtain wall is attached to a building frame installed on a foundation as an outer wall structure of a building. In this case, the displacement of the curtain wall due to the behavior of the building due to an earthquake or the like is small, The displacement can be absorbed by the cubic connecting portion of the curtain wall or the like.

[0003]

However, in the case of two buildings in which curtain walls are attached to the building frames respectively installed on independent foundations, the behavior of the two buildings due to an earthquake or the like is different. By connecting the curtain wall and the curtain wall of the other building, 1
In the case of a single building, the behavior of both curtain walls is different and the displacement of the connecting portion is large, so that the connecting portion may be damaged.

Accordingly, an object of the present invention is to provide an outer wall structure of a building capable of solving the above-mentioned problems.

[0005]

Means for Solving the Problems A pair of lower buildings 1, 1 which are installed on a first foundation at an interval in the left-right direction, and are located above the pair of lower buildings 1, 1, and The upper building 2 is installed on a second foundation independent of the first foundation, and the outer wall 8 is attached between the outer walls 1b, 1b of the pair of lower buildings 1, 1 and between the first foundation and the upper building 2. The outer wall 8 is composed of an upper outer wall 8a supported on the upper building 2 and a lower outer wall 8b supported on the first foundation, and a lower end of the upper outer wall 8a and an upper end of the lower outer wall 8b. Are connected so as to be relatively slidable in the in-plane direction and up-down direction and relatively displaceable in the out-of-plane direction, and the vertical edge of the upper outer wall 8a is formed on the outer wall 1b of the outer wall 1 of the lower building 1. The lower rim 8b is connected to the vertical edge by an expansion joint 110, and the lower outer wall 8b is The outer wall structure of the building is connected to the outer wall 1b lower.

[0006]

[Operation] The upper building 1 and the lower building 2 behave differently due to an earthquake or the like.
Is greatly displaced with respect to the lower outer wall 8b and the outer wall 1b of the lower building 1, but the displacement is absorbed by the connecting portion between the upper outer wall 8a and the lower outer wall 8b and the expansion joint 110. When the outer wall 1b and the outer wall 2b of the upper building 2 are connected by the outer wall 8 to form a single building in appearance, the connecting portion of the outer wall 8 is not damaged by an earthquake or the like.

[0007]

[Embodiment] As shown in FIG. 1 and FIG. 2, a building is composed of left and right lower buildings 1, 1 and an upper building 2. The left and right lower buildings 1, 1 are obtained by attaching a building foundation 3, for example, an outer wall 1b made of a curtain wall to a building frame 1a installed on the left and right portions of the remaining underground portion by removing the ground portion of an existing building, respectively. is there. Building foundation 3
And four pillars 6 are provided on a pillar foundation 5 independent of the above. An artificial ground 7 having a truss structure is attached between the upper parts of the four pillars 6, and the building frame 2a installed on the artificial ground 7 The upper building 2 is provided by attaching an outer wall 2b made of a curtain wall. The outer wall 1b and the artificial ground 7 of the lower building 1
