In this embodiment, the central support device 10 keeps the substantially central portion of the central support member 9 positioned substantially centrally of the joint portion 2 at all times. Instead of using the center support device 10, the center support member 9 may be positioned at the center of the joint by utilizing the biasing force of a spring such as a coil spring. Although it is desirable to always position the substantially central portion of the central support member 9 at the substantially central portion of the joint portion 2 in this way, a fall prevention means (not shown) is provided to prevent the central support member 9 from falling off the guide rails 12. ), the central support member 9 may simply be constructed so as not to drop off from the guide rail 12 .

Since the central support member 9 is provided between the one support member 7 and the other support member 8, the one support member 7 and the other support member 8 form a straight line in plan view with the central support member 9 interposed therebetween. One end is attached to one frame 3 or the other frame 4 with a space in the front-rear direction by a width for attaching the central support member 9 so as to form a shape.

The upper surfaces of one supporting member 7, the other supporting member 8, and the central supporting member 9 are connected so as to be substantially horizontal, so that the joint cover 6 can be efficiently supported.

The joint cover 6 has a central joint cover 14 whose substantially central portion is always positioned substantially centrally of the joint portion 2 and whose position is displaceable in the vertical direction, and a central joint cover 14 whose substantially central portion A center support device 10 which is always positioned substantially in the center of the part 2, and a pair of right and left sides which are provided so as to substantially abut against both ends of the center joint cover 14, respectively, and which have free ends formed with upwardly inclined surfaces 15.

The center joint cover 14 is a metal plate, and as shown in FIG. A support bar 19 extending in the front-rear direction is fixed to the bottom surface of the center joint cover 14 at the substantially central portion thereof, and the support bar 19 is supported by the joint cover support mechanism 5 . The support bar 19 is connected to the central support device 10 by a connecting member 20 , and the substantially central portion of the central joint cover 14 is always positioned substantially centrally of the joint portion 2 .

The connection member 20 is attached to the central support device 10 so as to be slidable in the vertical direction. Displace.

The pair of end joint covers 16 are metal plates, and as shown in FIG. 6, one end is fixed near one frame 3 or the other frame 4 . In this embodiment, a support bar 19 extending in the front-rear direction is fixed to the bottom surface of one end of the end joint cover 16 , and the support bar 19 is connected to the end pivotal support of the link member 18 . Also, the support bar 19 is always supported by the joint cover support mechanism 5 . One end of the end joint cover 16 may be fixed to the floor surfaces of the frames 3 and 4 or the like.

A push-up inclined surface 15 for pushing up the central joint cover 14 is formed on the projecting end of the end joint cover 16 .
In this embodiment, the pair of support covers 17 is a metal plate member formed in a flat plate shape or a downward U-shape when viewed from the front, as shown in FIG. A support bar 19 extending in the direction is fixed, and the support bar 19 is always supported by the joint cover support mechanism 5 .

A support bar 19 fixed to the bottom surface of the central portion is connected to a pivotal portion of a link member 18. The link member 18 keeps the center joint cover 14 and the pair of end joint covers 16 in contact with each other at all times. A central portion of the support cover 17 is located. As described above, in this embodiment, the link member 18 is used to position the support cover 17. However, the link member 18 is not used and a biasing member such as a spring is used to position the center joint cover 14 and the pair of end portions. It may be always positioned near the contact portion of the joint cover 16 .

The link member 18 is a pantograph-like member having a plurality of pivots, one end of which is attached to the wall surface of one of the skeletons 3 and the other end of which is attached to the wall of the other skeleton 4 . A plurality of link members 18 are provided at predetermined intervals in the front-rear direction, and two link members 18 are provided in this embodiment.

As shown in FIG. 8, a plurality of center support devices 10, two in this embodiment, are provided in the front-rear direction. , a pinion 22 which meshes with the pair of rack members 21 and whose center is always positioned approximately in the center of the joint portion 2 in the left-right direction; It is composed of a connection member 20 that is connected to a substantially central portion in the left-right direction of the cover 14 . By connecting the connecting member 20 to the substantially central portion of the central joint cover 14 in the horizontal direction, the central portion of the central joint cover 14 can always be positioned substantially in the central portion of the joint portion 2 in the horizontal direction. The connecting member 20 also serves as the central axis of the pinion 22, and is provided so as to be slidable in the vertical direction. Fixed to the bottom. As a result, the center support member 9 can also be positioned substantially at the center of the joint portion 2 .

One end of the rack member 21 is attached to the one frame 3 or the other frame 4 so as to be rotatable in the front-rear direction, and the tip portion is provided with a rotating portion 23 via a fulcrum 23a such as a pivot pin. ing. The rotating portion 23 rotates in the front-rear direction about the fulcrum 23a, and the tip portion is bent slightly outward. With this configuration, when the joint portion 2 becomes narrower, even if the tip portion of the rack member 21 is pressed against the wall surfaces of the facing frames 3 and 4, the rotating portion 23 at the tip rotates at the fulcrum 23a. and the rocking motion can be absorbed without damaging the rack member 21. - 特許庁In addition, it is desirable that the tip end portion and the pivotal support portion of the rack member 21 are provided with a biasing means (not shown) such as a spring so that the rack member 21 can be returned to the original position after being rotated.

When the left and right skeletons 3 and 4 sway in the left-right direction due to an earthquake and the joint 2 narrows, as shown in FIG. The joint cover 14 is displaced upward to absorb shaking motion caused by an earthquake.

When the frames 3 and 4 sway laterally due to an earthquake and the joint 2 widens, the end joint covers 16 slide away from each other as shown in FIG. 10 to absorb the sway caused by the earthquake. At this time, a gap is created between the protruding end of the end joint cover 16 and both ends of the center joint cover 14, but since the support cover 17 is positioned in this part, the joint 2 does not open and an earthquake can occur. It can absorb the shaking motion caused by
