Title: Expansion joint
Inventor: KOBAYASHI NOBUYUKI
IPC: E04B1/62
Filed: 1996-02-22
Abstract: PURPOSE: To prevent a skeleton face and a cover body from being damaged by absorbing the fluctuation of a gap between th skeletons in the connection of the skeleton faces through an expansion joint. CONSTITUTION: Supporting members 2, 2 are fixed at the corners of floors (a), (a) in the longitudinal direction of a gap A. A movable plate 3 is insertedly set on a lower side to spread a floor covering body 4 over the supporting member 2, 2 and the movable plate 3 so as to support from a back side. In addition to that, external facing bodies 5, 5 are coveringly attached from a surface side to coveredly close the gap A with the floor cover body 4 not abutting on an inner wall. The movable plate 3 has a width being able to spread over the supporting protrusive parts 2b, (2b) of the supporting members 2, 2, and length (t) along the length direction of the gap is formed shorter than the length (s) of a low stage part 2d to spread over the end of the movable plate to abut on the inner wall.  The length (s), (s) of the low stage parts 2d, 2d of the supporting members 2, 2, namely the length about twice as long as the length (t) of the gap A is secured as slidable width of the movable plate 3. Thus fluctuation in the direction of gap length can be absorbed by the movable plate 3.
