Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall surface joint device for covering joint portions between wall surfaces of left and right buildings built via joint portions.
[0002]
[Prior art]
Conventionally, this type of wall joint device supports one end portion of a joint cover that covers the joint portion between the wall surfaces on the housing of one building, and the other end portion is slidable along the wall surface of the other building. It is mounted using a mounting bracket that can be energized.
[0003]
[Problems to be solved by the invention]
In conventional wall joint devices, if the overlap between the other end of the joint cover and the wall surface of the other building is not set large, the other end of the joint cover will move if the left and right buildings are greatly shaken in different left and right directions due to an earthquake, etc. In addition to the disadvantage that the part enters the joint and damages it, the large joint cover makes handling difficult and difficult, and the strength of the mounting bracket has to be increased, resulting in high costs. It was.
