Description

  The present invention relates to a ceiling joint device for covering ceiling joint portions of left and right buildings provided via joint portions.

Conventionally, this type of ceiling joint device has a rear end attached to the left and right ceiling housings, and the front end is constructed using left and right ceiling panels that rise as the joints become narrower. There is one that uses a lifting mechanism using a wire that can be lifted upward when the joint is narrowed due to an earthquake, with the end portion attached and the tip of the ceiling panel located near the other ceiling housing.

  For this reason, when a shaking motion occurs due to an earthquake in which the width of the joint is half or 1.5 times the width, there is a disadvantage that a gap is generated in the ceiling joint, or the ceiling mechanism The lifting mechanism has to be provided at a height higher than the width of the joint portion from the position, and there is a drawback that it can be used only in a place with such a margin.

Japanese Patent No. 3817168 Japanese Patent No. 3611536

  In view of the above-described conventional drawbacks, the present invention can cover the joint portion without any gap even if the width dimension of the joint portion is halved or 1.5 times, and the upper surface of the ceiling panel. It is an object of the present invention to provide a ceiling joint device that can be installed without a large dimension and that can use a plurality of small ceiling panels.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
