Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a joint device for a seismic isolation building or the like that covers a joint portion between a wall of a lower outer wall of the base isolation building or the like and a wall provided via the joint portion.
[0002]
[Prior art]
Conventionally, a building such as a seismic isolation building has a joint part between a frame of the lower outer wall and the wall, and an expandable joint bag is used to directly cover the joint part.
[0003]
[Problems to be solved by the invention]
When using an expandable joint bag that directly covers the joint, the problem does not occur when the joint expands and contracts in the vertical direction. There was a drawback that it would not return to the state of.
[0004]
In view of the conventional drawbacks as described above, the present invention can directly restore the original joint state without damaging even when the joint portion expands or contracts in the vertical direction or shifts in the different left and right directions. The purpose is to provide joint devices such as seismic isolation buildings that can cover parts.

[0020]
(1) Joint part provided so that the upper part is pivotally attached to a housing of the lower outer wall of a building such as a seismic isolation building, and the lower part is movably contacted with the wall so as to be provided via the joint part. A joint cover covering one end of the joint cover, and one end of the joint cover is attached to the casing of the lower outer wall, and the other end of the joint cover can be guided in the lower part of the joint cover when the joint is widened or shifted in different left and right directions. Since it is composed of a plurality of extendable support wires attached to the upper part of the wall, the joint part swings due to earthquakes etc. in different left and right directions and rotates so that the lower end part of the joint cover enters the joint part In some cases, it can be moved by being supported by a plurality of support wires that can be expanded and contracted.
Therefore, it is possible to reliably prevent an accident in which the lower end portion of the joint cover enters the joint portion and is damaged due to the stop of the shaking motion.
[0021]
(2) According to the above (1), even if the joint portion expands and contracts or shifts in different left and right directions, the lower end portion of the joint cover moves up and down, or moves along a plurality of extendable support wires, The shaking motion can be absorbed without damage, and can be automatically restored to the original state when the shaking motion stops.
Therefore, no special maintenance work is required and it can be used easily.
[0022]
(3) Since the joint portion is directly covered by (1), it is not necessary to install a joint device or the like on the outer peripheral portion in order to cover the joint portion, and a large space is not required, and the joint portion can be installed compactly. it can.
[0023]
(4) According to the above (1), the structure is simple and can be easily installed.
