By moving up along, it is possible to escape from the relative displacement.

[0007]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to FIGS. In the drawings, A is a building, and B is an artificial ground formed around the building A, which is adjacent via a joint s. Although not shown, the lower part of the building A is supported by a seismic isolation device having a buffer function, and has a seismic isolation structure. Further, the joint s is formed with a predetermined width along the periphery of the building A, so that the joint s can absorb relative horizontal shaking between the building A and the surrounding ground B during an earthquake. I have.

On the upper surface of the side edge of the ground B, an inclined receiving edge 1 that is inclined at a gentle downward gradient toward the joint s is formed. A water channel 2 is formed at the lower edge of the inclined receiving edge 1, and rainwater or the like flowing from the upper surface 3 of the ground B is drained by the water channel 2 to remove rainwater or the like. The inflow to the joint s is prevented. A support member 4 for supporting a lower surface of a cover C, which will be described later, is provided on an upper edge of the inner wall 2 ′ of the water passage 2.

[0009] A cover C is provided between the building A and the ground B to cover the joint s. A plurality of the cover bodies C are continuously arranged along the longitudinal direction of the joint s. Each of the cover bodies C has a lower end at one end connected to an outer wall surface 5 of the building A as described later. The other end is a free end which is swingably connected via a means 6A, and the free end is formed with an inclined end 7 which is gently inclined from the lower surface toward the upper surface of the outer end. The slope end 7 has substantially the same slope as the slope receiving edge 1 of the ground B. The inclined end 7 is mounted on the inclined receiving edge 1 such that the upper surface 8 of the cover C is substantially flush with the upper surface 3 of the ground B.

[0010] The cover C has a rectangular peripheral frame which is vertically divided by a partition plate 9, an upper portion of which is formed with a concave portion 11 filled with a finishing material 10, and a lower portion of which has a plurality of members. The rigid base frame 13 is formed by arranging the crossbars 12a and the crossbars 12b in a grid pattern. The rigid base frame 13 has the same structure as that generally used as grating, and the rigid base frame 13 has a strength capable of withstanding a large load even if a large load is applied on the cover body C. I have. The front edge of the peripheral frame of the cover C is formed into an L-shaped cross section by a vertical plate portion 32a and a horizontal plate portion 32b projecting forward from the upper end of the vertical plate portion 32a. A plurality of generally triangular inclined plates 32c are disposed between the horizontal plate 32a and the horizontal plate portion 32b, and these are used as the inclined ends 7. The recess 11 is filled with a floor finishing material 10 made of mortar m, tile t and the like.

The cover C is not limited to the above-described structure as long as it has a strength capable of withstanding a predetermined load.

Next, the connecting means 6A will be described with reference to FIGS. A bracket 14 is provided on the outer wall surface 5 of the building A so as to extend along the longitudinal direction of the joint s. The bracket 14 is formed in an L-shaped cross section having a horizontal piece 14a and a vertical piece 14b, and the vertical piece 14b is fixed to a bolt 15 protruding from the outer wall 5 with a nut 16. Thereby, the horizontal piece portion 14a is projected horizontally outward from the outer wall surface 5 of the building A. As shown in FIG. 3, a support member 17 having a semicircular cross section is provided on the upper surface of the horizontal piece 14a. Arrangement The peripheral surface is formed as a supporting edge 18 which is in line contact with the lower surface of the cover C and supports the cover C in a swingable manner. The support edge 18 may be formed by forming the support 17 into a triangular cross section, and using the upper ridge line as the support edge 18. Thus, by providing the support 17 provided with the support edge 18 on the upper surface of the horizontal piece 14a, the fulcrum of the cover C when swinging is made constant.

Further, a plurality of connecting rods 19 composed of screw rods are erected at predetermined intervals on the horizontal piece 14 a of the bracket 14. Each connecting rod 19 is loosely fitted into an insertion hole 21 formed in a bottom plate 20 of the cover body C in a state where the lower surface of the cover body C is supported by the support edge 18, and a spring formed by a cap nut at the upper end thereof. The receiving member 22 is screwed. A coil-shaped spring 23 is fitted on each connecting rod 19 so as to be interposed between the spring receiving member 22 and the bottom plate 20 of the cover body C. C is constantly biased downward. As a result, one end of the cover C can swing with respect to the bracket 14.

Thus, a connecting means 6A is formed, and one end of the cover C is swingably connected to the outer wall 5 of the building A by the connecting means 6A. In this connection state, the upper surface 8 of the cover C is flush with the upper surface of the floor f of the building A.

In such a configuration, the cover body C is arranged such that the upper surface 8 on the free end side thereof is substantially flush with the upper surface 3 of the ground B. As shown, there is no step between the cover C and the ground B. Further, when the building A and the adjacent ground B are relatively displaced in the approaching direction during the earthquake, the cover C is moved with the one end connected by the connecting means 6A as a fulcrum, as shown in FIG. When the inclined end 7 formed at the free end is displaced along the inclined receiving edge 1 formed on the upper surface of the side edge of the ground B, it is possible to escape from the relative displacement. This can prevent the building A and the cover C from being damaged.

When the building A and the adjacent ground B are relatively displaced away from each other, the cover C is supported by the lower surface of the support member 4 as shown in FIG. Sliding on the support member 4, the free inclined end 7 separates from the inclined receiving edge 1 of the ground B and follows the relative displacement thereof. When the building A and the ground B return to their normal positions after the earthquake, the free end of the inclined end 7 is mounted on the inclined receiving edge 1 of the ground B, and the cover C is moved as shown in FIG. It returns to the steady state shown in 4a.

The joint cover device according to the present invention can be applied to a general building other than a building having a base-isolated structure whose lower portion is supported by a base-isolating device.

[0018]

[Effect of the invention]

 As described above, the present invention forms the inclined end 7 at the free end of the cover body C from the lower surface toward the upper surface of the outer end, while forming the inclined end 7 on the upper surface of the side edge of the ground B with substantially the same inclination as the inclined end 7. The inclined edge 1 of the cover C is mounted on the inclined edge 1 so that the upper surface 8 of the cover C is always attached to the upper surface of the ground B. 3 and can be kept substantially flush. As a result, it is possible to solve the conventional problem that the step at the entrance of the building A causes an obstacle such as traffic.

Further, when the building A and the adjacent ground B are relatively displaced in the approaching direction during the earthquake, the cover body C has an inclined end 7 formed at the free end and the upper surface of the side edge of the ground B. Since it is possible to escape from the relative displacement by moving up along the inclined receiving edge 1 formed in the above, there is an excellent effect that damage to the building A and the cover C can be prevented.
