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 part of the drawing) - down (lower part of the drawing) direction are defined based on FIG. 1, and the front (lower part of the drawing) - rear (upper part of the drawing) direction is defined based on FIG. 2.

[0012] In addition, in the present invention, the body 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 refers not only to an entrance provided with a door or a gate, but also includes 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 8, 1 is a joint device for a wall surface that closes the joint part 2 between one body 3 and the other body 4.

[0014] This joint device 1 for the wall surface is provided, for example, as shown in FIGS. 1 and 2, on at least one of the one body 3 or the other body 4, and a column 5 that extends in the vertical direction with its lower end supported by the one body 3 or the other body 4, a movable member 6 provided movably in the vertical direction on the column 5, a position adjusting means 7 for adjusting the vertical position of the movable member 6, a telescopic link mechanism 8 provided between the one body 3 and the other body 4, a joint cover attachment member 10 provided at a plurality of pivot parts 9 of the telescopic link mechanism 8, and a plurality of joint covers 11 whose one ends are respectively attached to the joint cover attachment member 10 and close the joint part.

[0015] In this embodiment, as shown in FIG. 3 for example, the support column 5 is a prismatic member provided on the wall surface on the joint portion side of the other housing 4, and its bottom is supported by a housing-shaped support portion 12 protruding from the other housing 4 toward the one housing 3 side. The upper end portion of the support column 5 protrudes upward beyond the upper end portion of the movable member 6 to be described later in this embodiment, and it is advisable to connect the vicinity of the upper end portion of the support column 5 to the other housing 4.

[0016] In this embodiment, the support column 5 is formed in a square pipe shape, but it may be formed in a prismatic shape, round pipe shape, cylindrical shape, etc., or may be a columnar member of other shapes.

[0017] In this embodiment, a square pipe-shaped movable member 6 is provided outside the support column 5 so as to be movable in the vertical direction. The movable member 6 is formed to be shorter than the support column 5, and the support column 5 protrudes in the vertical direction from the upper and lower end portions of the movable member 6.

[0018] The movable member 6 of this embodiment is inserted outside the support column 5 and is provided so as to be movable in the vertical direction while being guided. As shown in FIG. 1, the end portion on the other housing 4 side of the telescopic link mechanism 8 is connected. In this embodiment, the movable member 6 is supported by a connection member 13 that constitutes the position adjustment means 7. Specifically, a large number of through holes 14 are formed in the movable member 6 and the support column 5, and the pin-shaped connection member 13 is inserted so as to penetrate the through holes 14 of the movable member 6 and the support column 5 to support the movable member 6. Thereby, the load applied to the movable member 6 is supported by the support column 5 via the connection member 13. Note that only one connection member 13 may be used to connect the movable member 6 and the support column 5, but it is desirable to insert a plurality of connection members 13 into the through holes 14 to disperse the load. By the way, in this embodiment, the through holes 14 are formed in a staggered manner in the support column, but the through holes 14 may be provided in any arrangement.

[0019] In this embodiment, the position adjustment means 7 consists of a lifting device 15 connected to the movable member 6 and moving the movable member 6 in the vertical direction, and a connecting member 13 that connects the movable member 6 and the support column 5 and supports the load applied to the movable member 6 by the support column 5. When adjusting the position of the movable member 6 using the position adjustment means 7, the lifting device 15 is operated to move the movable member 6 in the vertical direction to position the movable member 6 in a predetermined position, and then the connecting member 13 is used to connect the movable member 6 and the support column 5 to adjust the vertical position of the movable member 6.

[0020] In this embodiment, the lifting device 15 uses a hoisting device, connecting a wire 16 or chain to the movable member 6, and moving the movable member 6 vertically by winding up the wire 16 or chain with the hoisting machine 17. After the movable member 6 has moved to the appropriate position, the movable member 6 and the support column 5 are connected with a pin-shaped connecting member 13 to position it. The support column 5 and the movable member 6 have through holes 14 formed at predetermined intervals into which the connecting member 13 is inserted.

[0021] Incidentally, a guide portion 18 with an elongated hole may be formed in the support column 5, and a pin-shaped guided portion 19 that engages with this guide portion 18 may be provided on the movable member 6. By providing such a guide portion 18, the movable member 6 can be moved without being swung in the left-right direction or other directions when it is moved in the vertical direction. Incidentally, in this embodiment, a wire 16 or the like is connected to the guided portion 19, and when vertical movement of the movable member 6 is required, the guided portion 19 is pulled up with the wire 16 or the like to move the movable member 6 almost vertically in the vertical direction. When a solid support column 5, such as a rectangular prism, is used, the wire 16 or the like may be connected near the upper end of the support column 5.

[0022] In this embodiment, the support column 5, the movable member 6, and the position adjustment means 7 are provided only on the other structural frame 4, but they may also be provided on both the structural frame 3 and the other structural frame 4. In such a case, both ends of the telescopic link mechanism are indirectly attached to the structural frame 3 and the other structural frame 4 via the movable member 6.

[0023] In this embodiment, the telescopic link mechanism 8 is composed of a number of roughly square-shaped link sections 21, which are so-called four-bar link-like structures formed by connecting link members 20 in a roughly square shape, and reinforcing link sections 22 formed between adjacent roughly square-shaped link sections 21, so that the telescopic link mechanism 8 as a whole is roughly trapezoidal. Note that a simple pantograph-shaped link mechanism or a link mechanism with another configuration may be used as the telescopic link mechanism 8. Furthermore, the telescopic link mechanism 8 may be connected to the movable member 6 or the left and right body sections 3 and 4 via angle-shaped mounting brackets or hinge members, and in this embodiment, it is attached via a hinge member 23.

[0024] In this embodiment, the reinforcing link portion 22 is constructed by extending the link material 20 that forms the link portion 21 upward or downward, connecting its end, and sharing two sides with the link portion. By further providing such a reinforcing link portion 22, the strength of the telescopic link mechanism 8 against deflection in the front-rear direction can be improved.

[0025] This telescopic link mechanism 8 is provided with connection points between link members 20 that do not shift position vertically even when the telescopic link mechanism 8 is extended or retracted, when the left and right ends are horizontal. 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.

[0026] 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 by a pivot pin 24 or the like via a mounting bracket (not shown) that is roughly U-shaped in cross-section. 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 24 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 24. 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 roughly perpendicular to the extending direction of the telescopic link mechanism 8.

[0027] 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.

[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 hoisting machine 17 of the position adjustment means 7 is operated to push the movable member 6 upward according to the amount of settlement. This makes it possible to complete the work more easily and in a shorter time than before.

[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 7, thereby absorbing the shaking caused by the earthquake.

[0030] 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 8, and the overlap width of adjacent joint covers 11 is reduced, thereby absorbing the shaking caused by the earthquake without the joint 2 opening.
