It is intended to provide a joint cover device that can be used for a long time.

The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a method in which left and right skeletons on the joint side of right and left buildings built through joints are placed in front and rear or vertical directions of the left and right skeleton surfaces. A pair of slide rails slidably mounted on the pair of slide rails, and a pair of slide rails having both ends attached thereto, and a center maintaining bar attached to a central portion being always located at a central portion between the pair of slide rails. At least two or more center maintaining link mechanisms, and both ends capable of constantly positioning the center maintaining bar at the front and rear of the left and right frames on the joint side of the left and right buildings or at the center of the upper and lower parts. A front / rear or up / down center maintenance device attached to the front / back or upper / lower portion of the skeleton, and a joint cover covering the joint portion attached to the center maintenance bar. Constitute a joint cover device.
