In the present invention, the framework refers to buildings, roads, slabs, elevator shafts, and other structures in which joint plates can be installed. It also includes passable passages.

As shown in FIGS. 1 to 3, for example, the floor joint device 1 includes a first joint plate support portion 5 provided on one skeleton 3 and a second joint provided on the other skeleton 4. a plate supporting portion 6; a plurality of joint plates 7 having one end supported by the first joint plate supporting portion 5 and the other end supported by the second joint plate supporting portion 6; A rod-shaped insertion member 8 provided at the bottom of the and extending downward in a substantially hanging state, one end of which is attached to the joint side wall surface 3a of the one skeleton 3 so as to be rotatable in the front-rear direction, and the other end a plurality of center maintaining devices 9 each of which is attached to the joint side wall surface 4a of the other skeleton 4 so as to be rotatable in the front-rear direction, and whose substantially center portions are always positioned substantially at the center of the joint portion 2; A girder member 10 connected to the central support device 9 and extending in the front-rear direction, and a cylindrical inserted member 11 provided on the girder member 10 and into which the insertion member 8 is inserted so as to be vertically slidable. It consists of

A recessed first joint plate support portion 5 is provided on the floor surface of one skeleton 3, and the floor surface of the other skeleton 4 has the same configuration as the first joint plate support portion 5. A second joint plate support portion 6 is formed. At the end of the first joint plate supporting portion 5 and the second joint plate supporting portion 6 opposite to the joint portion 2, there is a run-on inclined surface 12 on which the joint plate 7 rides when the joint portion 2 becomes narrow. , and a joint plate receiving portion 23 for supporting the bottom surface of the joint plate 7 is formed continuously with the run-on inclined surface 12 . The joint plate receiving portion 23 is formed so as to be slightly higher than the floor surface 3b of one frame 3 and the floor surface 4b of the other frame 4, and the joint plate is supported by the pair of left and right joint plate receiving portions 23. It has a length that can be held almost horizontally.

By forming such a joint plate receiving portion 23, even when artificial turf or the like is laid on the floor surfaces 3b and 4b of the one skeleton 3 and the other skeleton 4, the raised joint plate 7 can be removed. , which slides on the joint plate receiving portion 23, does not damage the floor surfaces 3b, 4b of the frame such as artificial turf and veneer.

All or part of the first joint plate supporting portion 5, the second joint plate supporting portion 6, the run-on inclined surface 12 and the joint plate receiving portion 23, or any portion of these portions may be replaced with a metal plate or the like. It may be covered with reinforcing means.

For example, as shown in FIG. 4, the joint plate 7 includes a shallow dish-shaped joint plate main body 13, a rod-shaped insertion member 8 provided substantially in the center of the bottom of the joint plate main body 13 in the left-right direction, and the joint plate. A filling member 14 such as cement or mortar filled in the plate main body 13, a decorative member 15 provided so as to cover the upper part of the filling member 14, and hinge members 16 provided at both ends of the joint plate main body 13. It is composed of a cover plate 17 that is

In the present embodiment, the insertion member 8 is a downwardly extending round bar-shaped member, and is provided at substantially the center of the bottom of the joint plate 7 in the left-right direction and the front-rear direction. The length of this inserting member 8 is such that when the joint plate 7 rises upward due to an earthquake, it does not drop off from the inserted member 11, which will be described later. Preferably, the joint plate 7 rises upward due to an earthquake. It is desirable to form the length so that it can be inserted into the inserted member 11 by about 100 mm. The insertion member 8 can be shaped like a pipe, a square bar, a square pipe, or the like, and can have an arbitrary cross-sectional shape as long as it is a long bar.
A plurality of insertion members 8 may be provided for one joint plate 7 .

The decorative member 15 may be a decorative board made of stone or plate material, but artificial grass is used as the decorative member 15 in the present embodiment. By using such a decorative member 15, for example, an artificial turf having a length of about 30 mm is laid between a base-isolated building as one skeleton 3 and a ground as a floor surface 4b of the other skeleton 4. When the joint part 2 exists, by providing a short artificial turf of about 10 mm as the decorative member 15, it becomes a state as if the artificial turf is laid all over, and the joint part 2 can be closed without a sense of incongruity. It can improve aesthetics.
A decorative member 15 such as an artificial turf can also be provided on the upper surface of the cover plate 17. By providing the decorative member 15 on the upper surface of the cover plate 17, the appearance can be further improved.

The central support device 9 has a pivot portion pivotally supported by a pivot pin so that a pair of left and right long rods 18a and 18b forming an angle in a front view with reference to FIG. It is composed of a link member 18 and a connection member 20 attached to a center pivotal support portion 19 positioned at the center of the upper end of the link member 18 and connected to the beam member 10 . Both ends of the upper end of the link member 18 are attached to the wall surface 3a on the side of the joint portion 2 of the one skeleton 3 and the wall surface 4a on the side of the joint portion 2 of the other skeleton 4 so as to be rotatable in the front-rear direction. . With this configuration, the pivotal support portion at the upper end is always arranged substantially horizontally, and even if the link member 18 expands and contracts, in other words, the angle formed by the pair of left and right elongated rods 18a and 18b having the substantially inverted mountain shape is maintained. The upper end of the link member 18 can be expanded and contracted while maintaining a substantially horizontal position even if the angle of the link member 18 increases or decreases.

By using such a center support device 9, even if the center support device 9 expands and contracts, it has little effect on the insertion member 8 and the like. can be kept stable.

A plurality of central supporting devices 9, four in this embodiment, are provided at predetermined intervals in the front-rear direction.

Since the connecting member 20 is attached to the central pivotal support portion 19 of the upper end portion of the link member 18 , it is always positioned substantially in the center of the joint portion 2 .

In this embodiment, the beam member 10 is a square pipe or square bar-shaped member, and the connection member 20 is fixedly or detachably connected to the substantially central portion in the left-right direction. As a result, the girder member 10 is always positioned substantially in the center of the joint portion 2 .

The beam member 10 is provided with a plurality of pipe-shaped inserted members 11 into which the insertion member 8 is inserted in a substantially fitted state at predetermined intervals.

The inserted member 11 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 10 . The lower end of the inserted member 11 is open, and the insertion member 8 may project downward beyond the lower end of the inserted member 11 . 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 11 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. 6, the joint plate 7 rises substantially vertically upward while maintaining a substantially horizontal state, slides laterally on the joint plate receiving part 23, 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 member to be inserted 11, preferably to a length that allows it to be inserted into the member to be inserted 11 by about 100 mm.

In addition, since the central support device 9 uses a link mechanism formed in a substantially inverted triangular shape when viewed from the front, even if the joint portion 2 becomes narrower and the link mechanism is deformed, it interferes with the insertion member 8 and the like. never.

Furthermore, since the upper surface of the joint plate receiving portion 23 is slid to absorb shaking motion due to an earthquake, damage to the floor surfaces 3b, 4b of the left and right frames 3, 4 can be reliably prevented.
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 longitudinal directions due to an earthquake, both ends of the central support device 9 rotate in the longitudinal direction, and both ends of the joint plate move toward the first joint plate support portion 5 and the second joint plate support portion 5. 2 joint plate supporting portion 6 is slid forward and backward to absorb shaking motion caused by an earthquake. In the present invention, since the insertion member 8 and the elongated member 11 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. 7 and 8 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. 7 and 8, the main difference from the first mode for carrying out the present invention is that a pair of rack member 21 and pinion 22 are used. In view of the fact that the central supporting device 9A is used, even if the floor joint device 1A using such a central supporting device 9A, the same effects as those of the first embodiment for carrying out the present invention can be obtained.

The central support device 9A of this embodiment includes one rack 21a having one end attached to the wall surface on the joint part 2 side of the one skeleton 3 and one end attached to the wall surface on the joint part 2 side of the other skeleton 4. and the other rack 21b, which is engaged with the pair of rack members 21, and a pinion 22 whose central portion is always positioned substantially in the central portion of the joint portion 2 so as to be substantially coaxial with the central portion of the pinion 22. and a connection member 20A connected to the beam member. In addition, even if the pair of rack members 21 (the rack 21a and the rack 21b) move in mutually different directions, the same movement as the pair of left and right elongated rods 18a and 18b that constitute the link mechanism of the first embodiment is possible. The object of the present invention can be achieved because it corresponds to the change in the lateral width of the joint portion 2 .

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.
