[0012] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, directions are referred to as left-right (horizontal), top (top of the drawing), and bottom (bottom of the drawing) directions based on Fig. 1. Directions are referred to as front (bottom of the drawing) and rear (top of the drawing) directions based on Fig. 2.

[0013] In the first form for implementing the present invention shown in Figures 1 to 8, in this embodiment, 1 is a joint device installed between left and right bodies 3 and 4 (in this embodiment, the body on the right side is one body 3 and the body on the left side is the other body 4) arranged via a joint portion 2.

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

[0015] In this embodiment, one of the frames 3 has a floor 3b and a passage-side wall 3c standing on the side of the floor, and a wall 3a on the joint section 2 side that is continuous with the floor 3b is provided with a first joint plate support 5. In addition, a curb 6 is formed on the joint section side wall 3a that is continuous with the passage-side wall 3c at a position higher than the floor 3b so as to protrude toward the other frame 4.

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

[0017] In this embodiment, the guide member 10 is provided by fixing a generally angle-shaped or crank-shaped metal fitting to the joint side wall surface 3a of one of the bodies 3. The length of this guide member 10 is set to a length that prevents the slide member 11 from falling off the guide member 10 when the one and other (left and right) bodies 3, 4 swing in different forward and backward directions.

[0018] In addition, the guide member 10 is positioned so that when the joint plate 8 is installed on the first joint plate support portion 5, the floor surface 3b of one of the bodies 3 and the upper surface of the joint plate are approximately flat.

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

[0020] The curb 6 is formed higher (above) than the floor surface 3b of one of the bodies 3, and in this embodiment, is formed to have a length approximately equal to the overall length (length in the left-right direction) of the joint plate. The curb 6 is formed so that its bottom surface is about 300 mm to 2000 mm above the floor surface 3b of one of the bodies 3.

[0021] A small gap, specifically a gap of about 50 mm, is formed between the upper end of the cover device 9 and the bottom of the berm 6. In the present invention, the cover device 9 may be used with such a gap formed that people, objects, etc. cannot get in.

[0022] By forming such a small gap, when an earthquake causes the left and right frames 3 and 4 to sway in different forward and backward directions, the cover device 9 can smoothly absorb the shaking caused by the earthquake without interfering with the shaking.

[0023] It is also possible to provide a bearing, roller, sliding member, etc. in this area without forming a gap.

[0024] The other body 4 is formed with a second joint plate support portion 7, which is a recessed portion formed in the floor surface 4a of the other body 4, and is formed so as to face the first joint plate support portion 5 via the joint portion 2. At the end of the second joint plate support portion 7 opposite the joint portion 2, a sloped surface 15 is formed on which the joint plate 8 climbs up during an earthquake.

[0025] In this embodiment, a second cover member 23 of a 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 is composed 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 and 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 panel 19 arranged to cover the top of the filling member 18, and a cover plate 21 arranged on the other end side of the joint plate body 16 so as to be rotatable in the vertical direction via a hinge member 20. In this embodiment, the joints 2 between the floor surfaces are closed by a plurality of joint plates 8. As the joint plates 8, various known joint plates can be used.

[0027] As shown in Figure 5, the cover device 9 is composed of an attachment member 14 whose lower end is fixed to the slide member 11, a first cover member 22 whose one end is fixed to the attachment member 14, extending in the left-right direction, and whose bottom roughly abuts the upper surface of the joint plate, a second cover member 23 which extends in the front-to-back direction and is arranged so as to roughly abut the other end of the first cover member 22 or the other body near the other end of the first cover member 22, and a third cover member 24 which is fixed near the upper end of the first cover member 22 and blocks the joint portion 2 so as not to open when the left and right bodies 3 and 4 sway in different front-to-back directions.

[0028] This cover device 9 covers the lower part near the outer periphery of the berm 6 to prevent people, animals, objects, etc. from entering below the berm 6, and is installed to prevent, for example, people from entering, animals from entering and settling in, and objects of a certain size, such as balls, from rolling in.

[0029] It should be noted that the term "almost" in "almost abutting" does not mean excluding the case of abutting, but includes not only a state of contact but also a state of being disposed with a slight gap. In this embodiment, the bottom of the first cover member 22 is preferably in contact with the upper surface of the joint plate 8 and is in a state of being supported.

[0030] The first cover member 22 is composed 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 on 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 fixed cover member 25 is formed on an inclined surface such that the vertical length of the end portion on the other frame side is shorter than the length on one frame side. As a result, when the other end portion of the joint plate 8 rotates upward and rises during an earthquake, the movable cover member 26 is pushed up and rotates around the hinge 27 as a fulcrum 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 provision of the hinge 27 can also prevent the movable cover member 26 from falling off the fixed cover member 25.

[0033] In addition, the bottom of the fixed cover member 25 may be made approximately horizontal, and 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, thereby absorbing the shaking caused by the earthquake so that the joint plate 8 does not collide with the fixed cover member 25.

[0034] In addition, 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 rather is in approximate contact with it.

[0035] In this embodiment, the fixed cover member is formed in a box shape 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 approximately like a lip channel steel when viewed in horizontal cross section.

[0036] In this embodiment, the second cover member 23 is a plate-like or wall-like member, the bottom of which is fixed to the floor surface 4a of the other body 4. In other words, it is formed so as to rise upward from the floor surface 4a of the other body 4. The upper end of this second cover member 23 is formed so as 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 so as to be approximately flush with the tip of the berm 6. The end of this second cover member 23 is provided so as to be in approximate contact with the other end of the first cover member 22.

[0037] Note that this 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 frame 4. In such a case, it is preferable to form the lower end so as to be in approximate contact with the floor surface 4a of the other frame 4, and provide a sliding member or the like at the bottom of the second cover member 23 so as to be supported by the floor surface 4a of the other frame 4. By providing such a sliding member, the second cover member 23 can be provided more stably, and when the left and right frames 3, 4 sway left and right due to an earthquake, the shaking can be smoothly absorbed.

[0038] The third cover member 24 is a plate-like member that is fixed to the first cover member 22 or is formed integrally with the first cover member 22 so that its bottom substantially abuts the upper end of the second cover member 23. By providing such a third cover member 24, it is possible to prevent people or objects from falling into the gap that would otherwise open in the joint portion 2 if an earthquake causes the left and right frames to sway in different forward and backward directions. Note that the third cover member 24 may be made of a bent plate-like member that covers the surface between the upper ends of the first cover member 22 and the second cover member 23 and the surface of one frame 3 that is parallel to the joint side wall surface 3a.

[0039] If the left and right bodies 3 and 4 shake 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 will climb up onto the sloped surface 15 and rise upward, and the movable cover member 26, pressed by the other end of the joint plate 8, will enter the inside of the fixed cover member 25, absorbing the shaking caused by the earthquake.

[0040] If the left and right bodies 3 and 4 shake due to an earthquake or other event, widening the joint area, the joint plate 8 slides left and right on the second joint plate support part 7, as shown in Figure 7, and absorbs the shaking caused by the earthquake.

[0041] If the left and right frames 3, 4 shake in different forward and backward directions due to an earthquake or the like, the joint plate 8 is pressed against the wall surface of the second joint plate support part 7 (the step with the floor surface of the other frame), as shown in Figure 8, and the joint plate 8 and cover device 9 shake in unison with the other frame 4, absorbing the shaking caused by the earthquake. At this time, if the berm 6 shakes in a direction away from the joint plate 8, the third cover member 24 closes the space between the berm 6 and the joint plate 8, preventing the joint part 2 from opening. [Industrial Applicability]

[0042] The present invention finds application in the jointing equipment manufacturing industry. [Explanation of symbols]
