Description

  The present invention relates to a ceiling joint cover device that covers joint parts of ceiling parts of left and right seismic isolation buildings built via joint parts.

  Conventionally, the tip of the joint cover that covers the joint of the ceiling is pivotably attached to the frame of one of the left and right buildings, and the tip of the joint cover is attached to the other building of the left and right buildings. It is configured to slidably contact one end portion of a ceiling member attached to the housing of the ceiling portion so as to absorb the expansion and contraction motion in the left-right direction.

The conventional ceiling joint cover device is useful in that it has a simple structure and can be easily installed, but when the joints on the left and right are repeatedly narrowed or widened due to shaking such as a severe earthquake. In addition, there is a drawback that the contact portion between the joint cover and the ceiling material is damaged or deformed due to a collision. For this reason, once an earthquake occurs, it must be replaced with a new joint cover or ceiling material, which is uneconomical.
