Fixing metal fittings, a plurality of cover supporting metal fittings that are attached to the fixing metal fittings and are bridged between the joints of the left and right buildings, and the plurality of cover supporting metal fittings are always in contact with the left and right frames. A mounting metal fitting attached to a support portion of the fixing metal fitting that is biased to come into contact with each other, and joints attached to the plurality of cover supporting metal fittings by a plurality of screws so as to cover the plurality of cover supporting metal fittings. It is composed of a cover.

[0003]

In the conventional joint cover device for the inner wall surface, since the supporting portion of the fixing metal fitting for supporting the cover supporting metal fitting is located in the joint portion, the fixing metal fitting is swayed by an earthquake or the like. There was a defect that the structure hits the supporting part of the and damages it, and the amount of swaying motion of the left and right buildings decreases.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
Even if the left and right buildings shake due to an earthquake, etc., it will not be damaged,
It is an object of the present invention to provide a joint cover device capable of covering the joint portion following the swaying movement and allowing the left and right buildings to sway by the width dimension of the joint portion.

[0005]

In order to achieve the above object, the present invention provides a cover attachment portion on the joint portion side fixed to one of the frames on the joint portion between adjacent left and right buildings. A fixing metal fitting having a bearing portion on the ground side, a cover mounting metal fitting having a cover mounting portion on the joint side, which is fixed to the other body near the joint, and a cover of the cover mounting metal fitting. One end is attached to the mounting part, the other end is attached to the cover of the fixing bracket, and the waterproof cover has a substantially Ω shape, and the bearing part of the fixing bracket is rotatably mounted at a predetermined interval. A plurality of cover supporting metal fittings, each of which has a shaft portion formed at its rear end portion and a tip portion of which protrudes so as to come into contact with the other skeleton body, and the tip portions of the plurality of cover supporting metal fittings are always connected to the other skeleton body. To the fixing brackets that urge them so that they touch each other. A joint cover including a plurality of urging members and a joint cover fixed to the cover support fitting with a plurality of screws to cover the joint by covering the plurality of cover support fittings. -It constitutes the device.

[0006]

In the joint cover device configured as described above, the cover mounting bracket is rotatable with respect to the bearing part of the fixing bracket even if the left and right buildings move in the front-rear, left-right and up-down directions, and the tip part is Since it is biased by the biasing device so as to come into contact with the other structure, the joint cover follows and keeps the joint part covered, and since the mounting bracket is not located at the joint part, the left and right buildings are jointed. It can sway by the width of the part.
