At least a pair of guide rails fixed in a substantially horizontal state to the left and right floor frames on the joint side, at least two guide rails having both ends slidably attached to the at least one pair of guide rails and pivoted at the center one or more X-shaped support links, a central support bar pivotally supported by pivot pins on the central pivots of at least two or more of the X-shaped support links, and substantially central portions of the plurality of joint plates. A joint plate center maintaining mechanism comprising engagement pins for moving the joint plate that is slidably inserted into the pin insertion holes formed in the center maintaining bar and fixed to both side portions. is known (Patent Document 1).

In such a floor joint device, two or more X-shaped support links are used, and the bar member that constitutes the support link must be formed longer than the horizontal dimension of the joint. There is a drawback that it is difficult to accurately position the centering bar in the center of the joint part because it bends in the direction and the front-rear direction.

In addition, the length of the support link is increased and the range of movement is increased, which limits the number of joint plate center maintenance mechanisms that can be provided.

As shown in FIG. 5 , the central support device 10 of the present invention used for the joint plate 7 has one end slidably provided in the front-rear direction on one of the skeletons 3 , and the other end slidably attached to the other skeleton 4 . A long rod member 19 attached so as to be rotatable in the front-rear direction, one end of which is attached to the one frame 3 so as to be slidable in the front-rear direction, and the other end of which is attached to the other frame 4 in the front-rear direction. It is composed of a pantograph-like link mechanism 20 that can be attached, and a connecting portion 9 that is connected to the link mechanism 20 and whose central portion is always positioned in the central portion of the joint.

The long rod member 19 is bridged between the one frame 3 and the other frame 4 in a state of being oblique in a plan view and maintaining a substantially horizontal posture, and one end side is the wall surface 3a of the one frame 3. A slide member 22 such as a roller is provided on a guide rail 21 provided on the one frame 3 so as to be slidable in the front-rear direction. The guide rail 21 is a substantially crank-shaped member when viewed in cross section, and is provided so as to extend in the front-rear direction on the wall surface 3a on the joint portion side of one of the skeletons 3. As shown in FIG. As the guide rail 21, a guide rail 21 having a substantially channel shape in cross section or a rail-shaped member composed of two or more parts may be used.

The other end of the long rod member 19 is rotatably mounted on the wall surface 4a of the other frame 4, and the other end of the link 23 constituting the link mechanism 20 is also pivotally supported. It is pivoted by pin 24 .

One end of the link mechanism 20 is provided so as to be slidable in the front-rear direction indirectly on the guide rail 21 via a sliding member 22, and the other end is indirectly attached to the wall surface of the other skeleton 4 via a mounting bracket. is rotatably pivotally attached to the . The link mechanism 20 is formed in a substantially rectangular shape in plan view, and the long rod member 19 also serves as one link 23 of the links 23 whose ends are pivotally supported by the other skeleton 4 . Specifically, the other end of a link 23 having one end attached to one of the skeletons is pivotally supported at a substantially intermediate portion of the long rod member 19, and the portion up to the intermediate portion of the long rod member 19 and the three links 23 are connected. A substantially square-shaped link mechanism 20 is configured by.

Moreover, a bar member 25 is pivotally supported in a state of being bridged between substantially intermediate portions of the opposing links 23 , and a connecting portion 9 is provided at the central portion of the bar member 25 .
In the present embodiment, the pin member 9 pivotally supported at the central portion of the bar member 25 serves as the connecting portion 9, the pin member 9 is connected to the beam member 11, and the beam member 11 is always substantially at the center of the joint portion 2. located in the department.

A plurality of center maintenance devices 10 are provided at predetermined intervals in the front-rear direction.

The inserted member 12 is a pipe-shaped member having a hole shape such that the inserted member 8 can slide in the vertical direction and is in a substantially fitted state. It is provided so as to extend below the plate thickness of the girder member 11 . The lower end of the inserted member 12 is open, and the insertion member 8 may protrude below the lower end of the inserted member 12 . Since it is possible to provide the insertion member 8 in a penetrating state in this way, the length of the member to be inserted 12 may be shorter than the length of the insertion member 8, but it is desirable to have a length of at least about 200 mm.

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, as shown in FIG. The joint plate 7 rises substantially vertically upward while maintaining a substantially horizontal state due to the run-on inclined surface 13 of 6, and absorbs shaking motion due to an earthquake. At this time, it is desirable to form the insertion member 8 to a length that does not fall off the inserted member 12, preferably to a length that allows it to be inserted into the inserted member 12 by about 100 mm.

When the frames 3 and 4 sway in the lateral direction due to an earthquake and the joint 2 widens, both ends of the joint plate 7 move toward the first joint plate supporting portion 5 and the second joint plate supporting portion 6 as shown in FIG. It slides left and right to absorb the shaking caused by an earthquake.

When the frames 3 and 4 sway in different front-back directions due to an earthquake, one end of the central support device 10 slides in the front-back direction, the other end rotates in the front-back direction, and both ends of the joint plate slides the first joint plate supporting portion 5 and the second joint plate supporting portion 6 in the front-rear direction to absorb shaking motion caused by an earthquake. In the present invention, since the insertion member 8 and the elongated member 12 to be inserted are in a substantially fitted state, the load applied to the insertion member 8 and the like can be dispersed.

[Different Modes for Carrying Out the Invention]
Next, different modes for carrying out the invention shown in FIGS. 8-10 will be described. In describing these different modes for carrying out the present invention, the same components as those in the first mode for carrying out the present invention are denoted by the same reference numerals, and duplicate descriptions are omitted.

In the second mode for carrying out the present invention shown in FIGS. 8 to 10, the main difference from the first mode for carrying out the present invention is that a hole-shaped or tubular connecting portion 9A is formed. The insertion member 8 is fixed to the substantially central portion of the bottom surface of the joint plate 7 by using the central support device 10A, and the insertion member 8 is directly inserted into the connection portion 9A without using the beam member 11 to attach the joint plate 7. In the point that it is positioned in the center of the joint portion 2, even in the center maintenance device 10A and the floor joint device 1A using the center maintenance device 10A, the first embodiment for carrying out the present invention is described. A similar effect can be obtained.

In the central support device 10A of the present embodiment, a bar member 25 is pivotally supported in a state of being bridged between substantially intermediate portions of the opposing links 23. A portion 9A is provided, and the insertion member 8 is inserted into the connecting portion 9A, so that the substantially central portion of the joint plate 7 can be positioned substantially centrally of the joint portion 2 at all times.

In the embodiment of the present invention, a joint plate using a shallow dish-shaped joint plate body is used, but other known joint plates may be used.

The present invention finds application in the industry of manufacturing floor joint systems.
