Furthermore, the end portion on the first joint plate receiving portion side is formed with a substantially angle-shaped fixing portion which is fixed in an embedded state to the second joint plate support portion. It is characterized by the following:

[0011] Claim 2 The floor joint device described herein is characterized by comprising: a substantially horizontal cover plate receiving portion formed to be continuous with the second inclined surface; a ramping inclined surface formed to be continuous with the cover plate receiving portion and on which the cover plate can be mounted during an earthquake; and a horizontal portion that is continuous with the ramping inclined surface and is substantially flat with the floor surface of the other structural body, wherein the height of the step difference between the cover plate receiving portion and the horizontal portion is substantially the same as the height of the cover plate. [Effects of the Invention]

[0012] As is clear from the above explanation, the present invention provides the following effects. (1) Claim 1 In the invention described above, the length of the second joint plate receiving portion is formed to be approximately the same as or longer than the assumed maximum width of residual deformation. Therefore, even if residual deformation occurs in the left and right structural members due to an earthquake, causing the joint to become somewhat narrower, the other end of the joint plate can be supported by the horizontal second joint plate receiving portion. Therefore, it can stably support the joint plate. (2) The height of the step between the first joint plate receiving portion and the second joint plate receiving portion is formed to be substantially the same as the height of the cover plate attached to the joint plate. Therefore, even when residual deformation occurs in the left and right building bodies or the like due to an earthquake and the joint portion becomes slightly narrow, the cover plate can be in a substantially horizontal state or a state where the protruding end portion is slightly downward. Therefore, it is possible to prevent the protruding end portion of the cover plate from protruding obliquely upward. (3) Claim 2 Also in the invention described in, the same effects as those in (1) to (2) can be obtained, and during normal times, the upper surface of the joint plate, the cover plate, the horizontal portion, and the floor surface of the other building body are substantially flat, and the joint portion can be passed more safely.

Mode for Carrying Out the Invention

[0014] Hereinafter, the present invention will be described in detail according to the mode for carrying out the present invention shown in the drawings. In the first embodiment for carrying out the present invention shown in FIGS. 1 to 8, reference numeral 1 denotes a floor joint device installed between one housing 3 and the other housing 4 provided via a joint portion 2. The left - right direction is the left - right direction in FIG. 1 (plan view) (the longitudinal direction of the joint plate 7), the front - rear direction is the up - down direction in FIG. 1 (the direction orthogonal to the left - right direction, the width direction of the joint plate 7), and the up - down direction is the up - down direction in FIG. 2 (the thickness direction of the joint plate 7). In the present invention, the housing refers to a structure on which a joint plate such as a building, a road, a slab, an elevator shaft, etc. can be installed, and the entrance / exit includes not only the entrance / exit provided with a door or a gate but also a passage through which people, vehicles, etc. can pass.

[0015] As shown in FIGS. 1 and 2, the floor joint device 1 of the present embodiment includes a first joint plate support portion 5 provided on one housing 3, a second joint plate support portion 6 provided on the other housing 4 so as to face the first joint plate support portion 5 via the joint portion 2, a joint plate 7 having one end portion supported by the first joint plate support portion 5 and the other end portion supported by the second joint plate support portion 6, and a guide plate 8 provided on the second joint plate support portion 6. A first joint plate support portion 5 is formed on one housing 3. In the present embodiment, as shown in FIG. 3, the first joint plate support portion 5 is a recess - shaped portion formed to extend in the front - rear direction on the floor surface on the joint portion 2 side of one housing 3. A locking pile 10 inserted into a pile case 9 provided on the joint plate 7 is provided on the first joint plate support portion 5.

[0016] In this embodiment, a recessed first joint plate support portion 5 is formed in one of the structural members 3. However, an angle-shaped or crank-shaped metal fitting or the like may be fixed to the wall surface on the joint portion 2 side of one of the structural members 3 to serve as the first joint plate support portion 5. On the floor surface of the other structural frame 4, a second joint plate support portion 6 is formed so as to face the first joint plate support portion 5 via the joint portion 2. This second joint plate support section 6 is formed to a length that allows the joint plate 7 to slide from side to side during an earthquake. In addition, a guide plate 8 is provided near the end of the second joint plate support section 6 opposite to the joint section 2, and is provided so as to cover its surface from near the end of the second joint plate support section 6 opposite to the joint section 2 to the floor surface of the other structural frame 4.

[0017] As shown in Figures 3 and 4, the guide plate 8 is composed of a substantially horizontal first joint plate receiving portion 11 that receives at least the bottom of the other end of the joint plate 7, a first inclined surface 12 formed to be continuous with the first joint plate receiving portion 11 and on which the joint plate 7 can ride up during an earthquake, a substantially horizontal second joint plate receiving portion 13 formed to be continuous with the first inclined surface 12, a second inclined surface 14 formed to be continuous with the second joint plate receiving portion 13 and on which the joint plate can ride up during an earthquake, a substantially horizontal cover plate receiving portion 15 formed to be continuous with the second inclined surface 14, a ride-up inclined surface 17 formed to be continuous with the cover plate receiving portion 15 and on which the cover plate 16 can ride up during an earthquake, and a horizontal portion 18 continuous with this ride-up inclined surface 17.

[0018] In other words, a flat first joint plate receiving portion 11, a first inclined surface 12, a second joint plate receiving portion 13, a second inclined surface 14, a cover plate receiving portion 15, a ride-up inclined surface 17, and a horizontal portion 18 are continuously formed from the joint portion 2 side.

[0019] The upper surface of the first joint plate receiving portion 11 is provided to be substantially flat with the upper surface of the second joint plate support portion 6 without any step difference, and the height of the step difference between the first joint plate receiving portion 11 and the second joint plate receiving portion 13 is formed to be substantially the same height as the height of the cover plate 16 attached to the joint plate 7.

[0020] Furthermore, the length of the second joint plate receiving portion 13 is formed to be approximately the same as or longer than the assumed maximum width of residual deformation when the left and right structural members undergo residual deformation due to an earthquake. As a result, even if the left and right structural members undergo residual deformation, the other end of the joint plate 7 can be reliably supported by the horizontal portion, and the joint plate 7 can be stably supported.

[0021] In this embodiment, the guide plate 8 is formed by bending a metal plate, and a substantially angle-shaped fixing portion 19 is formed at the end on the side of the first joint plate receiving portion 11, which is fixed in an embedded state to the second joint plate support portion 6 of the other structural body 4. The height of the guide plate 8 from the first joint plate receiving portion 11 to the horizontal portion 18 is formed to be approximately the same as the height (thickness) of the joint plate 7, and the height of the step between the cover plate receiving portion 15 and the horizontal portion 18 is formed to be approximately the same as the height of the cover plate. Therefore, under normal circumstances, the upper surface of the joint plate 7, the upper surface of the cover plate 16, the horizontal portion 18, and the floor surface of the other structural frame 4 are formed to be approximately flat. Incidentally, it is desirable that the other end (protruding end) of the cover plate 16 be formed to be curved or to be an inclined surface at approximately the same angle as the ramping inclined surface 17. By forming it in this way, the cover plate 16 can rise more smoothly onto the ramping inclined surface 17 during an earthquake. Furthermore, in this embodiment, the first joint plate receiving portion 11 of the guide plate 8 is formed to receive only the vicinity of the other end of the joint plate 7. However, the entire second joint plate support portion 6 may be covered by the first joint plate receiving portion 11, and it may be formed to receive the entire other end of the joint plate 7.

[0022] As shown in Figure 5, for example, the joint plate 7 consists of a metal joint plate body 20 that is roughly rectangular in plan view and formed in the shape of a shallow dish, pile cases 9 provided on both sides of one end of the joint plate body 20, a filling member 21 such as mortar or concrete filled inside the joint plate body 20, a decorative plate 22 such as marble tiles or bricks attached to the upper surface of the filling member 21, and a cover plate 16 attached to the other end of the joint plate body 20 via a hinge member 23. In this embodiment, a shallow dish-shaped joint plate body 20 filled with a filling material 21 is used, but a solid (thick plate-shaped) joint plate body 20 may also be used to construct the joint plate 7.

[0023] In normal operation, as shown in Figures 1 and 2, for example, one or more of these joint plates 7 are provided in the front-to-back direction (up-and-down direction with respect to Figure 1) of the joint 2. In this state, one end of the joint plate 7 is supported when the locking pile 10 provided on the first joint plate support part 5 is inserted into the pile case 9 formed at one end, and the other end is directly or indirectly supported (via the guide plate 8) on the second joint plate support part 6. In this embodiment, multiple joint plates 7 are provided, and adjacent joint plates 7 are arranged with virtually no gaps in the front-to-back direction, while there is a gap of approximately 2 mm between adjacent joint plates 7. However, "virtually no gaps" includes not only the state where adjacent joint plates 7 are in contact, but also the case where there is a slight gap of a few millimeters between them.

[0024] Furthermore, although the drawing shows an example where the lid of the pile case 9 is exposed on the surface of the joint plate 7, it is also possible to configure it so that the pile case 9 is not exposed on the upper surface of the joint plate 7 (almost the entire surface is covered with a decorative panel).

[0025] When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to narrow, the joint plate 7 rides up over the first inclined surface 12 and the second inclined surface 14, as shown in Figure 6, absorbing the shaking caused by the earthquake. Normally, once the shaking caused by the earthquake stops, the joint plate 7 and cover plate 16 automatically return to their original state, becoming nearly horizontal.

[0026] However, if residual deformation occurs in the left and right structural members 3 and 4 due to an earthquake, they will not return to the normal state shown in Figure 1, etc. Instead, the bottom of the other end of the joint plate 7 will be supported by the second joint plate receiving portion 13, and the other end of the cover plate 16 will be supported in a nearly horizontal state by the horizontal portion 18 or the floor surface of the other structural member. As a result, the joint plate 7 will be stably supported on a horizontal portion, and the protruding end of the cover plate 16 will not protrude diagonally upward. When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to widen, the joint plate 7 slides from side to side on the second joint plate support 6, as shown in Figure 8, absorbing the shaking caused by the earthquake.

[0027] [Different forms for carrying out the invention] Next, different embodiments for carrying out the present invention shown in Figures 9 to 12 will be described. In describing these different embodiments for carrying out the present invention, the same reference numerals are used for components identical to those in the first embodiment for carrying out the present invention, and redundant descriptions are omitted. In the second embodiment for carrying out the present invention shown in Figures 9 to 12, the main difference from the first embodiment for carrying out the present invention is that the guide plate 8A does not have a cover plate receiving portion and a ramping inclined surface, and the floor joint device 1A uses this guide plate 8A. Even with such a floor joint device 1A, the same effects and advantages as in the first embodiment for carrying out the present invention can be obtained. In this embodiment, a horizontal portion 18 is formed so as to be continuous with the second inclined surface, but this horizontal portion 18 is not necessarily required. [Industrial applicability]
