PROBLEM TO BE SOLVED: To provide a floor joint device that can absorb swaying without breakage of a joint plate, a cover plate and a floor skeleton even if differential settlement occurs in left and right floor skeletons due to an earthquake.SOLUTION: A floor joint device 1 is constituted of: multiple support bars 4 attached to left and right floor skeletons 3 provided through a joint part 2; a bearing plate 5 attached to the upper surface of multiple support bars 4; a joint plate 6 supported to the bearing plate 5; and a cover plate 8 provided across a space 7 where the joint plate 6 slides on the upper part of the bearing plate 5. The support bar 4 comprises: multiple cylindrical support arms 10 with a rear end attached to any of the left and right floor skeletons 3, and having a roller 11 in an upper inner wall; and multiple insertion support arms 13 where the tip part having a roller 12 is inserted into the cylindrical support arm 10 and the rear end is attached to the other floor skeleton 3 facing any one of the floor skeletons 3 attached with the support arm 10.SELECTED DRAWING: Figure 2 |
