A plurality of telescopic bars slidably supported by a guide rail fixed substantially horizontally on the joint side of one floor surface, and the plurality of telescopic bars are always stored in the rotary lifting bar. A plurality of lifting mechanisms composed of a plurality of urging springs for urging the urging bar, and pivoting so as to project upward due to the pivoting of the pivoting bar when the joint portion becomes narrow due to an earthquake or the like. Then, a plurality of push-up pieces rotatably supported by the frame on the joint side of the other floor surface that pushes up a portion near the other end of the joint plate upwards, and the joint are damaged by an earthquake or the like. The joints become narrower Since it is composed of a joint plate slide movement mechanism that slides one end of the plate onto one floor surface, if the joint portion becomes narrow due to an earthquake, etc., one end of the joint plate will be moved to one floor surface. The other end of the joint plate can be slid upward, and the other end of the joint plate can be rotated and pushed upward by the rotation raising bar of the raising mechanism so that the joint plate can be positioned in a substantially horizontal state. Therefore, it is possible to prevent a dangerous state in which one end of the wedge-shaped joint plate is inclined as in the conventional case and the joint plate protrudes above one floor surface.
