A slide member 9 such as a roller is provided on a support portion 11 of the support rail 5 , and a bar-shaped joint plate support 10 extending in the front-rear direction is supported by the slide member 9 . The joint plate 7 is supported on this joint plate support 10 . That is, the joint plate 7 is indirectly supported at its one end by the support portion 11 of the support rail 5 via a slightly thick elongated joint plate support 10 .

The joint plate support 10 is formed in a cross-sectional shape such as a prismatic shape substantially engaged with the support portion 11 of the support rail 5 or a square pipe shape with both ends closed. each protruding in the front-rear direction from the end in the front-rear direction. In this embodiment, a plurality of locking piles 14 for attaching the joint plate 7 are fixed to the joint plate support 10 .

Here, when a plurality of joint plates 7 are used, the term "ends in the front-rear direction of the joint plate 7" in the present invention refers to the joint plate 7 located at the end of the plurality of joint plates 7. front end (7a) or rear end (7b) of the That is, the front end 7a of the joint plate 7 located on the frontmost side and the rear end 7b of the joint plate 7 located on the rearmost side are the "ends in the front-rear direction of the joint plate 7" ( See Figure 3).

Next, on the floor surface of the other skeleton 4, there is formed a recessed joint plate supporting portion 6 in which the other end portion of the joint plate 7 can be slid in the left-right direction. At the end opposite to the joint part 2 of the joint plate supporting part 6, there is formed a run-up inclined surface 12 on which the other end of the joint plate 7 rides when the joint part 2 becomes narrower due to an earthquake.

Next, as shown in FIGS. 2 and 4, for example, the joint plate 7 is provided with a shallow dish-shaped joint plate body 13 and both sides of one end of the joint plate body 13 to support the joint plate. A pair of cylindrical pile cases 15 with an open bottom into which locking piles 14 fixed to the body 10 are inserted, and a filling member 16 such as cement or mortar filled in the joint plate main body 13 (see FIG. 2). ), a decorative plate 17 provided to cover the upper portion of the filling member 16, a cover plate 19 provided at the other end of the joint plate main body 13 via a hinge member 18, and an end on the front or rear side. It is composed of a cover member 8 provided on the part.

When the joint portion 2 is covered with a plurality of joint plates 7 as in this embodiment, the cover member 8 is not provided for the joint plate 7A located in the middle.

In this embodiment, the cover member 8 is a rail-shaped member that has a substantially angular cross section and extends in the front-rear direction. is provided in The cover member 8 may have any shape as long as it can cover the support rails 5. For example, the cover member 8 may have a substantially crank-shaped or circular-arc cross-sectional shape.

The lid body 21 is fixed to the cover member 8 so as to substantially abut on the front-rear end of the support rail 5. By providing such a lid body 21, fallen leaves and the like are reliably prevented from entering. can.

In addition, a biasing member 22 such as a coil spring is provided with one end attached to the lid 21 and the other end attached to the joint plate support 10 . and the cover member 8 is urged substantially against the joint plate support 10 .

When the left and right frames 3 and 4 sway in the left-right direction due to an earthquake and the joint portion 2 narrows, the other end of the joint plate 7 is pushed up by the joint plate support portion 6 on the inclined surface 12 as shown in FIG. The other end rises upward and absorbs shaking caused by an earthquake.

When the frames 3 and 4 sway laterally due to an earthquake and the joint portion 2 widens, the other end of the joint plate 7 slides laterally on the upper surface of the joint plate support portion 6 as shown in FIG. Absorbs vibrations.

When the frames 3 and 4 sway in different longitudinal directions due to an earthquake, the joint plate 7 slides in the longitudinal direction on the support rails 5 as shown in FIG. 7 to absorb the swaying motion caused by the earthquake. At this time, since one end of each of the joint plates 7 is attached to the joint plate support 10 by the locking pile 14, the joint plates 7 and the joint plate support 10 are integrated. to slide forward and backward.
In the state shown in FIG. 7, the rear cover member 8 slides forward and backward in synchronism with the joint plate support 10, but the front cover member 8 slides along the lid 21 and the ends of the support rails 5. abut to prevent sliding movement of the cover member 8 and remain in its normal position out of alignment with the joint plate support 10, leaving the gap between the cover member 8 and the end 7a of the joint plate 7 at the joint. covered by a plate support 10; As a result, even when shaking due to an earthquake, the shaking can be absorbed without opening the support rails 5 . When the shaking movement due to the earthquake ends, the joint plate 7, the cover member 8 and the like automatically return to their normal state.
