DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lid, for example, provided between a seismic isolation structure and a non-seismic isolation structure to cover a gap between the two structures.

[0002]

2. Description of the Related Art Conventionally, in a base-isolated building supported on a foundation via a base-isolation device, a base-isolation device including a base-isolator 2 and a damper 3 is usually provided as shown in FIG. For protection, the lower part of the building 1 is housed in a recess 5 provided in the ground 4 or in an area surrounded by a protective wall. Then, the building 1 is built at a predetermined distance from the retaining wall 6 and the protection wall of the recess 5 so that the building 1 can move in the horizontal direction at the time of an earthquake or a strong wind.

For this reason, a gap is formed between the non-seismic structure including the retaining wall 6 and the protective wall and the base-isolated building 1. The purpose is to prevent people and objects from falling into the gap. In order to protect the seismic isolation device from the external environment such as wind and rain that affects the seismic isolation device 2 and 3 through the gap, the non-seismic structure 6 is used.
A lid for shielding a gap is provided between the base and the seismic isolation structure 1.

[0004] The gap between the non-seismic isolated structure 6 and the seismic isolated structure 1 changes because the relative positions of the two structures 1 and 6 are relatively displaced during an earthquake or a strong wind. The amount of change in the gap at that time depends on the magnitude of the vibration of the ground 4 and the swing of the seismic isolation structure 1, and the degree of change is large.

Conventionally, the above non-seismic structure 6 and seismic isolation structure 1
As a lid for shielding the gap between the building 1 and the building 1, there is a projecting floor 7 projecting from the lower part of the base-isolated building 1 so as to cover the gap between the retaining wall 6 and the building 1. In the event of an earthquake or strong wind, the building 1 jumps out of the floor 7
A gap is formed between the lower surface of the jumping floor 7 and the upper end surface of the retaining wall 6 so as to be able to move up, down, left, and right without being disturbed by.

[0006]

However, the above-mentioned conventional lids for seismic isolation structures have the following problems.
That is, considering the horizontal movement of the building 1 at the time of an earthquake or a strong wind, the amount of protrusion of the jumping floor 7 from the outer wall of the building 1 is as follows.
Retaining wall 6 and building 1 at least by horizontal movement a of building 1
It is necessary to set more than the gap with the outer wall of the vehicle.
However, in an urban area where buildings are densely populated, buildings are often built close to the adjacent land boundary line 8, and the horizontal movement amount a cannot be secured on the adjacent land side in some cases. Furthermore, even if the rising floor 7 falls within the neighboring land boundary line 8, even if the tip of the rising floor 7 crosses the neighboring land boundary line 8 and damages the neighboring building due to horizontal movement of the building 1 during an earthquake or strong wind, etc. There is also.

Further, as described above, wind and rain enter from the gap between the lower surface of the pop-out floor 7 and the upper end of the retaining wall 6 provided to facilitate the movement of the building 1 during an earthquake or a strong wind, This has an adverse effect on the seismic isolation devices 2 and 3. In particular, in winter or summer, the rubber member used for the isolator 2 may harden or soften under the influence of the cold or hot air entering from the gap, and the seismic isolation devices 2 and 3 may deviate from the applicable range and malfunction. Occurs.

Accordingly, an object of the present invention is to provide a movable lid which can reliably cover a gap between two structures without exceeding one of the structures when a gap between the structures changes. It is in.

[0010] In the above structure, the object falling from above toward the gap between the two structures is blocked by the movable plate provided between the two structures and enters the gap. Will be blocked. In this state, when the gap between the two structures changes, the lower end of the movable plate body is rotatably attached to the one structure, while the upper end is on the wall surface of the outer wall of the other structure. Since it can be moved smoothly, the inclination angle is changed. Thus, the gap between the two structures is covered without the relative movement of the two structures being hindered by the presence of the movable lid.

[0011]

Further , an upper end, which is a free end of the movable plate, is covered by the cover without being hindered from moving. Thus, rain is prevented from entering the gap between the two structures from the gap at the upper end of the movable plate.

By configuring the movable lid 18 as described above, the free casters 23 provided on the upper end 21a of the movable plate 21 can move freely on the outer wall 11a of the building 11, while A free caster 27 provided at the lower end can freely move on the movable plate 21. further,
The movable plate 21 includes an outer wall 11 a and a retaining wall 16 of the building 11.
The mounting angle of the lower end 21b can be freely changed according to the change of the distance between the lower end 21b and the lower end 21b. As a result, the building 11 is
Can be moved up, down, left, and right with respect to the retaining wall 16 without being disturbed by the existence of the. Therefore, even if the distance between the outer wall 11a of the building 11 and the retaining wall 16 fluctuates, the movable plate 21 remains
The space between the outer wall 11a of the building 11 and the retaining wall 16 can be completely covered while being attached. In other words, the outer wall 11a and the retaining wall 16
The movable lid 18 is moved to the adjacent
It does not invade inside.

By constructing the movable cover 18 as shown in FIG. 2, the movable cover 18 covers the gap between the outer wall 11a of the building 11 and the retaining wall 16 without intruding into the adjacent ground boundary line 19. Can be. However, the seismic isolation device 12,
From the viewpoint of completely protecting the device 13 from the external environment, it is difficult to say that the device 13 is complete because there is still a gap between the movable plate 21 and the cover 22.

Therefore, in FIG.
8 comprises the movable plate 21 and the leaf spring 31 described above. The upper end of the leaf spring 31 is fixed to the lower surface of the eave 25 of the building 11 by the metal fitting 32, and the lower lower surface is adhered to the upper surface of the movable plate 21 by elastic force. And, between the lower surface of the leaf spring 31 and the upper surface of the movable plate 21,
A gap filling material 33 attached to the lower end of the leaf spring 31
Is closed by. By doing so, there is no gap between the movable plate 21 and the leaf spring 31, and the isolator 12 can be protected from the outside air in winter or summer, and the hardening and softening of the rubber member can be prevented. The movable plate 21 is pressed against the outer wall 11 a of the building 11 by the elastic force of the leaf spring 31. Therefore, it is possible to prevent the movable plate 21 from being shaken by the strong wind.

The material of the movable lid 18 is not particularly limited, but by using a stainless steel material, the durability against rain is improved, and the movable lid 18 can be used semipermanently.
