Mode for Carrying Out the Invention
[0011] Hereinafter, the present invention will be described in detail according to the mode for carrying out the present invention shown in the drawings. In this specification, the left-right direction, the up (upper side of the drawing) - down (lower side of the drawing) direction are defined based on FIG. 1, and the front (lower side of the drawing) - rear (upper side of the drawing) direction is defined based on FIG. 2.
[0012] In addition, in the present invention, the structure refers to a building such as a building, a road, a slab, an elevator shaft, etc. where a joint plate can be installed, and the entrance / exit includes not only the entrance / exit where a door or a gate is provided, but also a passage through which people, vehicles, etc. can pass.
[0013] In the first mode for carrying out the present invention shown in FIGS. 1 to 9, reference numeral 1 denotes a joint device for a wall surface that closes the joint part 2 between one structure 3 and the other structure 4.
[0014] As shown in FIGS. 1 and 2 for example, this joint device 1 for a wall surface includes a pair of guide members 5 extending in the vertical direction fixedly provided on one housing 3 and the other housing 4 respectively, a bar-shaped movable member 6 provided movably in the vertical direction on each of the pair of guide members, a position adjusting means 7 for adjusting the vertical position of the movable member 6 in a telescopic link mechanism 8 connected to one housing 3 and the other housing 4, a plurality of telescopic link mechanisms 8 each having left and right end portions attached to the movable member 6 and provided at a predetermined interval in the vertical direction, a joint cover attachment member 10 connected to a pivot support portion 9 of the telescopic link mechanism 8 and extending in the vertical direction, and a plurality of joint covers 11 each having one end portion attached to the joint cover attachment member 10 and closing the joint portion 2.
[0015] The pair of guide members 5 in this embodiment is, for example, a square pipe-shaped member having a slit 12 formed in the longitudinal direction at a substantially central portion of one side wall as shown in FIG. 3. And as shown in FIG. 4, a bottom plate-shaped base member 13 constituting the position adjusting means 7 is fixed to the lower end portion thereof so as to substantially close the bottom. In this embodiment, the guide member 5 is formed in a square pipe shape, but it may be formed in a round pipe shape or may be a rail member of other shapes. For example, a guide member having a substantially crank shape or a substantially U shape in cross-section may be used, and a movable member 6 that is movably engaged or externally fitted in the vertical direction may be provided on this guide member. In such a case, the slit 12 may not be formed in the guide member 5.
[0016] In this embodiment, a rectangular pipe-shaped movable member 6 is provided inside the guide member 5 so as to be movable in the vertical direction. As shown in Figure 1, the left and right ends of the telescopic link mechanism 8 are connected to the left and right movable members 6 via slits 12. In this embodiment, a mounting portion 6a is formed on the movable member 6 that passes through the slits 12 and protrudes toward the telescopic link mechanism 7, and the left and right ends of the telescopic link mechanism 7 are attached to this mounting portion 6a. Alternatively, the telescopic link mechanism 7 may be directly attached to the movable member 6 without forming such a mounting portion 6a. Furthermore, any shape is acceptable as long as the telescopic link mechanism 8 can be connected to it. In this embodiment, the movable member 6 is fitted into the guide member 5 and is provided to be movable in the vertical direction while being guided. In this embodiment, the bottom of the movable member 6 is supported by the position adjustment means 7.
[0017] The position adjustment means 7 consists of a base member 13 provided on the guide member 5 or the left and right structural members (one structural member 3 or the other structural member 4), and a support member 14 that is screwed onto the base member 13 and whose upper end supports the bottom of the movable member 6. By rotating the support member 14, the movable member 6 is moved in the vertical direction, and the vertical position of the movable member 6 is adjusted.
[0018] While it is desirable to provide the guide member 5, movable member 6, and position adjustment means 7 on both the one structural frame 3 and the other structural frame 4 as in this embodiment, they may be provided on only one of them depending on the installation situation of the left and right structural frames 3 and 4. In such cases, one end is attached to either the one structural frame 3 or the other structural frame 4 via the movable member 6, and the other end is directly or indirectly attached to the wall surface of either structural frame 3 or the other structural frame 4. That is, for the structural frames 3 and 4 that are provided with the guide member 5, movable member 6, and position adjustment means 7, the telescopic link mechanism 8 is attached to the movable member 6, and for the structural frames 3 and 4 that are not provided with the guide member 5, movable member 6, and position adjustment means 7, the telescopic link mechanism 8 is directly or indirectly attached to the wall surface of either structural frame 3 or the other structural frame 4.
[0019] In this embodiment, the guide member 5 is formed as a single long rail member, and the movable member 6 is formed as a single bar located inside this rail member. However, multiple guide members 5 and movable members 6 may be provided near the mounting portion of the telescopic link mechanism 8. In such cases, position adjustment means 7 are also provided for each guide member 5, etc.
[0020] In this embodiment, the base member 13 is a plate-shaped member fixed to the bottom of the guide member 5 by welding or the like, and a screw hole 15 into which the support member 14 is screwed is formed approximately in the center of the base member 13.
[0021] In this embodiment, the support member 14 is a bolt 14, which is screwed into the screw hole 15 (female thread) with its head 14a positioned downwards, and the upper end of the bolt 14 (the end opposite the head, the flat part of the screw tip) supports the movable member 6. Alternatively, a support plate that does not rotate in conjunction with the bolt may be provided at the upper end of the bolt 14, and this support plate may support the bottom of the movable member 6. The length of the screw portion 14b of the bolt 14 is formed to be longer than the expected range of movement due to uneven settlement. By rotating this support member 14 (bolt 14), the upper end of the support member 14 is displaced vertically, and as a result, the movable member 6 supported by the support member 14 is displaced vertically. Since the telescopic link mechanism 8 is connected to the movable member 6, the end of the telescopic link mechanism 8 is also displaced vertically in conjunction with the positional displacement of the movable member 6. As a result, if either the left or right structural frame 3 or 4 sinks, the position adjustment means 7 can be used to displace the movable member 6 on the side of the sinking structural frame 3 or 4 upward, thereby adjusting (repairing) the joint cover 11 so that its lower end, etc., is approximately horizontal, just as it was before the sinking. Incidentally, the telescopic link mechanism 8 may be connected to the movable member 6, etc., via angle-shaped mounting brackets or hinge members, etc.
[0022] The telescopic link mechanism 8 may be a simple pantograph-like link mechanism in which so-called four-bar link sections 17, formed by connecting link members 16 in a roughly square shape, are arranged in a roughly straight line in the left-right direction. However, in this embodiment, it is composed of a number of roughly square-shaped link sections 17 arranged in a roughly straight line in the left-right direction, and reinforcing link sections 18 formed between adjacent roughly square-shaped link sections 17, so that the telescopic link mechanism 8 as a whole is roughly trapezoidal. As mentioned above, a simple pantograph-like link mechanism or a link mechanism with another configuration may also be used as the telescopic link mechanism 8.
[0023] In this embodiment, the reinforcing link portion 18 is constructed by extending the link material 16 that forms the link portion 17 upward or downward, connecting its end, and sharing two sides with the link portion. By further providing such a reinforcing link portion 18, the strength of the telescopic link mechanism 8 against deflection in the front-rear direction can be improved.
[0024] This telescopic link mechanism 8 is provided with connection points between link members 16 that do not shift position vertically even when the telescopic link mechanism 8 is extended or retracted, when the left and right ends (attachment points to the movable member 6) are in a horizontal position. These connection points are designated as pivot points 9. A bar-shaped joint cover mounting member 10 for attaching the joint cover 11 is connected to this pivot point 9 either directly or indirectly via mounting brackets or the like.
[0025] The joint cover mounting member 10 is a bar-shaped member such as a rectangular prism or rectangular pipe, and is connected to the pivot 9 of the telescopic link mechanism 8. The joint cover mounting member 10 can be any shape as long as it can accommodate the joint cover 11, and is preferably bar-shaped, but is not limited to this. For example, a plate-shaped member may be fixed to the pivot 9, and this plate-shaped member may be used as the joint cover mounting member 10 to attach the joint cover 11, or the pivot pin that pivots the pivot 9 may be used as the joint cover mounting member 10, and the joint cover 11 may be attached to this pivot pin. In the present invention, since multiple telescopic link mechanisms 8 are provided in the vertical direction, the joint cover mounting members 10 are connected to the pivots of the upper and lower telescopic link mechanisms 8 respectively, and are provided so as to be substantially perpendicular to the extending direction of the telescopic link mechanism 8.
[0026] In this embodiment, the joint cover 11 is a plate-shaped joint cover formed in a roughly crank shape, with one end fixed to the joint cover mounting member 10. The other end overlaps with the adjacent joint cover 11, and during an earthquake, the width of this overlap changes to absorb the shaking caused by the earthquake.
[0027] In this embodiment, the end joint covers 11a located at the ends of one structural body 3 side and the other structural body 4 side of the joint cover 11 have window-shaped openings 19 near the lower end of the end joint cover 11a, which allow the support member 14 of the position adjustment means 7 to be operated, and a cover member 20 is further provided to cover these window-shaped openings.
[0028] Figure 5 shows the case where either one of the structural members 3 or the other structural member 4, in this embodiment, the other structural member 4, settles. When the other structural member 4 settles, the lower end of the joint cover 11 becomes stepped, like a staircase descending towards the settled other structural member 4. In this state, if the width of the joint 2 changes due to an earthquake, the lower end of the joint cover 11 may collide with the floor joint plate, floor joint device (not shown), the floor surface of the left and right structural members 3 and 4, etc., and be damaged. When such uneven settlement occurs, as shown in Figure 6, the cover member 20 is removed to expose the opening 19, and the bolt 14, which is the support member 14, is rotated from this opening 19 to push the movable member 6 upward according to the amount of settlement. As a result, as shown in Figure 7, the support member 14 can be operated from the opening 19 to repair the uneven settlement, so the work can be completed easily and quickly. Furthermore, even if no openings 19 are provided, the uneven settlement can be repaired by removing only one of the end joint covers 11a and manipulating the support member 14, making the work significantly easier and quicker than in the conventional method.
[0029] When the left and right structural members 3 and 4 sway during an earthquake, causing the joint 2 to narrow, the expansion link mechanism 8 contracts in the left-right direction and displaces itself so that the overlap width of adjacent joint covers 11 increases, as shown in Figure 8, thereby absorbing the shaking caused by the earthquake. When the left and right structural members 3 and 4 sway during an earthquake, causing the joint 2 to widen, the expansion link mechanism 8 extends in the left-right direction, as shown in Figure 9, and the overlap width of adjacent joint covers 11 is reduced, thereby absorbing the shaking caused by the earthquake without the joint 2 opening.
[0030] [Different forms for carrying out the invention] Next, different embodiments for carrying out the present invention shown in Figures 10 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.
[0031] In the second embodiment for carrying out the present invention shown in Figures 10 to 12, the main difference from the first embodiment for carrying out the present invention is that a position adjustment means 7A is provided which is a substantially angle-shaped base member 13 fixed to the wall surface of one structural frame 3 and the other structural frame 4. Even with a wall joint device 1A using such a position adjustment means 7A, the same effects and advantages as in the first embodiment for carrying out the present invention can be obtained.
[0032] In the embodiment of the present invention, a position adjustment means comprising a base member and a support member screwed into the base member was used. However, other position adjustment means may also be used, such as suspending the movable member from above with a bolt or the like, or moving the movable member vertically by passing a bolt through it and rotating the bolt, or providing an engaging member on the wall surface that is vertically movable and capable of supporting the movable member, and adjusting the position by engaging the movable member with the engaging member. Furthermore, when suspending the movable member from above, it is preferable to form an opening near the upper end. [Industrial applicability]
