[0012] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, the left-right direction (horizontal direction), up (upper part of the drawing), and down (lower part of the drawing) direction are used with reference to Figure 1. The front (lower part of the drawing) and back (upper part of the drawing) directions are used with reference to Figure 2.

[0013] In the first embodiment for carrying out the present invention shown in Figures 1 to 8, 1 is a joint device installed between left and right structural bodies 3 and 4 (in this embodiment, the right structural body is referred to as one structural body 3, and the left structural body as the other structural body 4) via a joint portion 2.

[0014] As shown in Figures 1 to 3, for example, this joint device 1 consists of one (right) structural body 3, another (left) structural body 4 provided with the first structural body 3 via a joint 2, a first joint plate support 5 provided on the first structural body 3, a walkway 6 provided on the wall surface 3a of the first structural body 3 on the joint 2 side so as to protrude toward the other structural body 4, a second joint plate support 7 provided on the other structural body 4 so as to face the first joint plate support 5 via the joint 2, a joint plate 8 with one end slidably supported in the front-rear direction by the first joint plate support 5 and the other end supported by the second joint plate support 7, and a cover device 9 provided on the first joint plate support 5 so as to be slidable in the front-rear direction, which can prevent people, animals, objects, etc. from entering below the walkway 6.

[0015] In this embodiment, one body 3 has a floor surface 3b and a passage side wall surface 3c erected on the side of this floor surface. A first joint plate support portion 5 is provided on the wall surface 3a on the joint portion side continuous with the floor surface 3b. Further, a dogleg 6 is formed at a position higher than the floor surface 3b of the joint portion side wall surface 3a continuous with the passage side wall surface 3c so as to protrude toward the other body 4 side.

[0016] The first joint plate support portion 5 is composed of a rail-shaped guide member 10 provided so as to extend in the front-rear direction on the wall surface 3a on the joint portion side of the one body 3, and a bar-shaped slide member 11 slidably supported in the front-rear direction by the guide member 10.

[0017] In this embodiment, the guide member 10 is provided by fixing a substantially L-shaped or substantially crank-shaped metal fitting to the joint portion side wall surface 3a of the one body 3. The length of this guide member 10 is formed to be such a length that the slide member 11 does not drop off from the guide member 10 when the one and the other (left and right) bodies 3 and 4 sway in different front-rear directions.

[0018] Further, the guide member 10 is provided at a position such that the floor surface 3b of the one body 3 and the upper surface of the joint plate are substantially flat in a state where the joint plate 8 is installed on the first joint plate support portion 5.

[0019] Preferably, a sliding member 12 such as a roller or a sliding material is provided at the bottom of the slide member 11. A plurality of locking piles 13 to be inserted into a pile case 17 provided at one end side of the joint plate 8 are fixed to the upper surface of the slide member 11, and a mounting member 14 constituting the cover device 9 is fixed thereto.

[0020] The dogleg 6 is formed at a higher position (above) than the floor surface 3b of the one body 3, and in this embodiment, is formed to have a length substantially the same as the total length (length in the left-right direction) of the joint plate. The bottom surface of this dogleg 6 is formed to have a height of about 300 mm to 2000 mm from the floor surface 3b of the one body 3.

[0021] A small gap, specifically about 50 mm, is formed between the upper end of the cover device 9 and the bottom of the dog run 6. In the present invention, the cover device 9 may be used with such a gap that prevents people or objects from entering.

[0022] By creating such a small gap, when the left and right structural bodies 3 and 4 sway in different front-to-back directions during an earthquake, the cover device 9 can smoothly absorb the seismic swaying without hindering it.

[0023] Alternatively, instead of creating a gap, bearings, rollers, or lubricants may be installed in this area.

[0024] A second joint plate support portion 7 is formed on the other structural frame 4. This second joint plate support portion 7 is a recessed portion formed on the floor surface 4a of the other structural frame 4, and is formed to face the first joint plate support portion 5 via the joint portion 2. At the end of this second joint plate support portion 7 opposite the joint portion 2, an overhanging inclined surface 15 is formed on which the joint plate 8 will ride during an earthquake.

[0025] Furthermore, in this embodiment, the second cover member 23 of the cover device 9, which will be described later, is provided on the floor surface 4a near the second joint plate support portion 7.

[0026] In this embodiment, as shown in Figure 4, the joint plate 8 consists of a shallow dish-shaped joint plate body 16, pile cases 17 formed at both ends of one end of the joint plate body 16 into which the locking piles 13 are inserted, a filling member 18 such as mortar or concrete filled into the joint plate body 16, a decorative plate 19 provided to cover the upper part of the filling member 18, and a cover plate 21 provided on the other end of the joint plate body 16 so as to be rotatable in the vertical direction via a hinge member 20. In this embodiment, multiple joint plates 8 are used to seal the joints 2 between floor surfaces. Furthermore, various known joint plates can be used for the joint plates 8.

[0027] As shown in Figure 5, the cover device 9 consists of a mounting member 14 whose lower end is fixed to the slide member 11, a first cover member 22 whose one end is fixed to the mounting member 14 and which extends in the left-right direction and whose bottom is substantially in contact with the upper surface of the joint plate, a second cover member 23 which is provided so as to substantially contact the other end of the first cover member 22 or the other building structure near the other end of the first cover member 22 and which extends in the front-rear direction, and a third cover member 24 which is fixed near the upper end of the first cover member 22 and closes the joint portion 2 so as not to open when the left and right building structures 3 and 4 swing in different front-rear directions.

[0028] This cover device 9 covers the lower part of the outer perimeter of the dog run 6 to prevent people, animals, objects, etc. from entering below the dog run 6. For example, it is installed to prevent people from entering, animals from getting in and settling down, and objects of a certain size, such as balls, from rolling in.

[0029] In this context, "approximately in contact" does not mean excluding cases of contact, but rather includes not only contact but also cases where there is a slight gap between them. In this embodiment, preferably, the bottom of the first cover member 22 is in contact with and supported by the upper surface of the joint plate 8.

[0030] The first cover member 22 consists of a fixed cover member 25, which is fixed near one end to the mounting member 14 and has an open bottom, and a movable cover member 26, which is inserted into the bottom of the fixed cover member 25 and whose bottom is supported by the upper surface of the joint plate 8.

[0031] In this embodiment, the fixed cover member 25 is formed so that its lower end is inclined, and one end of the movable cover member is attached to the fixed cover member via a hinge 27.

[0032] Specifically, the other end of the fixed cover member 25 on the building structure side is formed on an inclined surface such that its vertical length is shorter than the length of the other end on the building structure side. This allows the movable cover member 26 to be pushed up when the other end of the joint plate 8 rotates upward and rises during an earthquake, and rotates around the hinge 27 as a pivot point to enter the interior of the fixed cover member, thereby absorbing the shaking so that the joint plate 8 does not collide with the fixed cover member 25. In addition, the hinge 27 prevents the movable cover member 26 from falling off the fixed cover member 25.

[0033] Furthermore, the bottom of the fixed cover member 25 may be made approximately horizontal, so that when the other end of the joint plate 8 rotates upward during an earthquake, the movable cover member 26 is pushed up and moves vertically, entering the interior of the fixed cover member, and the structure can absorb the shaking caused by the earthquake so that the joint plate 8 does not collide with the fixed cover member 25.

[0034] Alternatively, a stopper or the like may be provided on the hinge 27 or the like to prevent the bottom of the movable cover member 26 from rotating below horizontal, so that the bottom of the movable cover member 26 does not come into contact with the upper surface of the joint plate 8, but is in near contact with it.

[0035] By the way, in this embodiment, the fixed cover member is formed in the shape of a box with an opening at the bottom, but it may also be formed in a shape that allows the movable cover member 26 to be inserted into the bottom, for example, a shape that is roughly like a lip-shaped channel steel in a horizontal cross-sectional view.

[0036] In this embodiment, the second cover member 23 is a plate-shaped or wall-shaped member, with its bottom fixed to the floor surface 4a of the other structure 4. In other words, it is formed to rise upward from the floor surface 4a of the other structure 4. The upper end of this second cover member 23 is formed to be at approximately the same height as the upper end of the first cover member 22, and the surface of the second cover member 23 is provided to be approximately flush with the tip of the dog run 6. The end of this second cover member 23 is provided to be in approximately contact with the other end of the first cover member 22.

[0037] Furthermore, the second cover member 23 may be provided on the other end side of the first cover member 22, rather than on the floor surface 4a of the other structural frame 4. In such a case, the lower end should be formed so as to be in substantially contact with the floor surface 4a of the other structural frame 4, and a sliding material or the like should be provided at the bottom of the second cover member 23 so that it is supported by the floor surface 4a of the other structural frame 4. By providing such a sliding material, the second cover member 23 can be provided more stably, and the shaking can be smoothly absorbed when the left and right structural frames 3 and 4 shake in the left and right directions due to an earthquake.

[0038] The third cover member 24 is a plate-shaped member that is fixed to the first cover member 22 or integrally formed with the first cover member 22 such that its bottom portion substantially abuts against the upper end of the second cover member 23. By providing such a third cover member 24, it is possible to prevent the joint portion 2 from opening up and people or objects from falling into the gap when the left and right structural bodies sway in different front-to-back directions due to an earthquake. Alternatively, the third cover member 24 may be made of a bent plate material and configured to cover the surface between the upper end of the first cover member 22 and the upper end of the second cover member 23 with a plate-shaped member, and the surface parallel to the joint portion side wall surface 3a of one of the structural bodies 3.

[0039] When the left and right structural members 3 and 4 sway due to an earthquake or other event, causing the joint to narrow, as shown in Figure 6, the other end of the joint plate 8 rides onto the ramping inclined surface 15 and rises upward, and the movable cover member 26, pressed by the other end of the joint plate 8, enters the interior of the fixed cover member 25, absorbing the shaking caused by the earthquake.

[0040] If the left and right structural members 3 and 4 sway due to an earthquake or other event, causing the joint to widen, the joint plate 8 slides horizontally on the second joint plate support 7, as shown in Figure 7, absorbing the shaking caused by the earthquake.

[0041] When the left and right structural bodies 3 and 4 sway in different front-to-back directions due to an earthquake or the like, as shown in Figure 8, the joint plate 8 is pressed against the wall surface of the second joint plate support 7 (the step between it and the floor surface of the other structural body), and the joint plate 8 and cover device 9 sway in sync with the other structural body 4, absorbing the swaying caused by the earthquake. At this time, if the walkway 6 sways in a direction away from the joint plate 8, the third cover member 24 can close the space between the walkway 6 and the joint plate 8, thereby preventing the joint 2 from opening.
