  In addition, even if the left and right buildings 2 and 5 swing in different directions in the front and rear directions and the left and right, the opposite ends of the left and right buildings 2 and 5 that are the other building absorb the shaking motion. Existing handrails and wall joint devices can be installed as needed.

  In the floor joint device 1 having the above configuration, the passages 3 and 6 of the left and right buildings 2 and 5 are normally located between the cover plates 25 and 25 and the cover plates 25 and 25 as shown in FIGS. It is covered with a plurality of joint plates 24 and can travel safely.

  When the left and right buildings 2 and 5 are swung so that the joint part 4 becomes narrow due to the earthquake, the central support bar 13 is positioned at the center part of the joint part 4 by the central maintenance links 11 and 11 as shown in FIG. The both ends of the joint plate support bars 15, 15, 15, 15, 15 are pivotally supported by the central support bar 13 with the pivot pins 16, 16, 16, 16, 16. It will be in the state which entered into the inside of the recessed parts 7 and 7, and it will be in the state in which a few number of joint plates 24 were located between the cover plates 25 and 25, and absorbs the shaking motion.

  The slide movement of the pair of joint plate slide support recesses 7 and 7 of the joint plate support bars 15, 15, 15, 15, 15 is caused by the bottom surfaces near both ends of the joint plate support bars 15, 15, 15, 15, 15. The rollers 14, 14, 14, 14, 14, 14, 14, 14, 14, 14 are smoothly moved.

Therefore, both ends of the joint plate support bars 15, 15, 15, 15, 15 that are pivotally supported by the center support bar 13 by the pivot pins 16, 16, 16, 16, 16 are a pair of joint plate slides. The support recesses 7 and 7 are slid and moved to the joint portion side, and a large number of joint plates 24 are positioned between the cover plates 25 and 25 to absorb the shaking motion.

  When the left and right buildings 2 and 5 are swung in different front and rear directions due to the earthquake, the joint plate support bars 15, 15, 15, 15, and 15 are moved in the front and rear directions by the left and right guide means 18 and 18, as shown in FIG. Since the joint plate 24 is pivoted, the joint plates 24 pivotally supported by the joint plate support bars 15, 15, 15, 15, 15 with the pivot pins 19 are in the front-rear direction and the contraction gap 20 is small. It slides so as to absorb the shaking movement.

  At this time, since the plurality of joint plates 24 slide and move in the front-rear direction, it is possible to prevent a gap from being generated on the floor surface at both ends between the passages 3 and 6 of the left and right buildings 2 and 5.

  In this state, even if the left and right buildings 2 and 5 swing in different left and right directions, the above-described operations are combined to absorb the swinging motion.
