[0002]
[Prior art]
For example, as shown in FIG. 3, in the case where a dirt floor 53 of a garage 52 of an automobile is constructed in a seismically isolated building 51, a high floor is constructed using beams under the floor, so that it corresponds to at least the garage 52. The base 54 of the part to be dug down is dug, and the dirt floor 53 is dropped into the dug down part. In the figure, 55 is a slope, and 56 is a seismic isolation device interposed between the foundation 54 and the column 57.
[0003]
In addition, when installing an elevator in a base-isolated structure, particularly a base-isolated house, a pit is required under the floor. In this case as well, as in the case of the garage 52 described above, the foundation is at least partially provided. It was necessary to dig down and drop the floor to fit.
[0004]
[Problems to be solved by the invention]
However, when constructing the garage 52 or elevator floor described above, at least part of the foundation must be dug down, and an elevated floor with beams under the floor must be dropped into the dug up part, making the construction complicated. In addition, there was a problem that the risk of rainwater flowing into the foundation that was dug up increased.
[0005]
In addition, when the floor used for the garage 52 or the elevator is cut directly from the upper seismic isolation building body and directly constructed on the ground, the vehicle, the elevator, the storage shed, the shelf or the like and the exemption Since it is necessary to secure a certain space as a slide allowance for seismic isolation between the seismic building bodies, there is a problem that is disadvantageous in terms of space utilization.
[0006]
Furthermore, when installing a carport around the exterior of the seismic isolation building body, the seismic isolation building body and carport are installed in the same way as when a car, elevator or installation is stored in the seismic isolation building body. It is necessary to secure a space as a slide allowance for a predetermined seismic isolation, and there is a problem that becomes disadvantageous in space utilization.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Specifically explaining an embodiment of a MenShinyuka structure according to the present invention with reference to FIG, 1 is a longitudinal sectional simplified view of MenShinyuka structure of a first embodiment according to the present invention, FIG. 2 exemption of Reference Example It is a longitudinal section simplification figure of a seismic floor structure.
[0011]
The seismic isolation floor structure of the first embodiment will be described with reference to FIG. 1. Reference numeral 1 denotes a seismic isolation building body, and each seismic isolation device is provided between each pillar 2 and the foundation 3 of the seismic isolation building body 1. 4 is interposed. 5 is a floor surface of a residential part.
[0012]
Reference numeral 6 denotes a garage provided in the seismic isolation building main body 1, and a slope 7 is provided at the entrance. A floor pallet 8 capable of forming a low floor on which a car, an elevator, or the like can be placed is laid on the floor surface of the garage 6, and a predetermined space is provided between the floor pallet 8 and the ground surface 3 a of the foundation 3. A horizontally movable device 9 having a friction degree of 5 is interposed. The floor pallet 8 is detachably connected to a predetermined position of the seismic isolation building main body 1 via a detachable connecting device (not shown).
[0013]
The horizontally movable device 9 is composed of, for example, a rolling device such as a bearing or a caster, or a sliding device configured by stacking synthetic resin panels having a desired sliding surface. As with the seismic isolation device 4 provided between the base 2 and the foundation 3, the floor pallet 8 placed on the horizontally movable device 9 can be moved while being regulated with predetermined friction. It is configured.
[0014]
In the first embodiment described above, in constructing the floor of the garage 6, the horizontally movable device 9 having a low height is provided between the floor pallet 8 laid on the floor and the ground surface 3a of the foundation 3. Since a low floor is formed by interposing it, it is not necessary to form a high floor with a beam under the floor as in the prior art, and for that purpose, a conventional digging down part on the foundation 3 corresponding to the floor of the garage 6 is provided. There is no need to provide.
[0015]
Therefore, as shown in the figure, the foundation 3 corresponding to the floor of the garage 6 can be formed on the same plane as the foundation 3 of the dwelling part. Can be prevented.
[0016]
Further, a horizontally movable device 9 having a predetermined friction is interposed between the floor pallet 8 laid on the floor of the garage 6 and the ground surface 3a, and the floor pallet 8 is connected via a connecting device. Since it is connected to the base-isolated building main body 1, the floor pallet 8 can be moved following the base-isolated building main body 1 in the event of an earthquake.
[0017]
Therefore, it is not necessary to secure a seismic isolation slide cost that is conventionally required between the vehicle, the elevator, the storage, and the installation in the base isolation building body 1. For this reason, the space in the seismic isolation building body 1 can be used effectively.
[0018]
In the case of the first embodiment of the present invention, the garage 6 has a feature that the underfloor beam as in the prior art can be made unnecessary. However, by omitting the underfloor beam, there is a problem that the column 2 provided at the entrance of the garage 6 is likely to vibrate independently from the base isolation building body 1. Therefore, in the present invention, the floor pallet 8 is interposed between the column 2 at the entrance of the garage 6 and the column 2 on the center side of the base isolation building body 1 as described above. Since both the pillars 2 and 2 are connected to each other, the two pillars 2 and 2 can be integrated to prevent only one pillar 2 from vibrating separately or greatly.
[0019]
Referring to MenShinyuka structure of Reference Example In Fig. 2, in the case of this reference example, a reference example of installing a carport close to the outer periphery of the seismic isolation building body 1.
[0020]
In the figure, 10 is a carport, which is installed close to the outside of the seismic isolation building body 1. A floor pallet 8 similar to that of the first embodiment is laid on the floor in the carport 10. In addition, the horizontally movable device 9 is interposed between the floor pallet 8 and the ground 11 such as a paved surface cured by pouring the ground surface or concrete. The carport 10 is connected and fixed to the seismic isolated building body 1 through a connecting device 12 so as to be detachable.
[0021]
In this reference example, since the floor of the carport 10 is composed of the floor pallet 8 having the structure as described above, the carport 10 follows the seismic isolation building body 1 in the event of an earthquake or the like. Can be moved. Accordingly, in this case, it is not necessary to secure a slide allowance for seismic isolation between the seismic isolation building body 1 and the carport 10, and the carport 10 can be installed close to the seismic isolation building body 1. I can do it. Therefore, the laying space can be used effectively.
[0022]
In the first embodiment and the reference example, the floor pallet 8 is used on the floor of the garage 6 or the carport 10, and the horizontal surface between the bottom surface of the floor pallet 8 and the ground surface 3a or the ground 11 is used. Since the movable device 9 is interposed, when the floor pallet 8 is separated from the seismic isolation building body 1 and made independent by releasing the connecting device, a desired place is left with the automobile on the floor pallet 8. Can be moved to.
[0023]
【The invention's effect】
In the present invention, in the floor structure is installed in MenShinKen was low floor using a floor pallet capable of forming, in the device or sliding device or the like rolling on the ground surface or the ground on the floor pallet Since it is installed directly through a horizontally movable device having a predetermined degree of friction, it is not necessary to dig up the foundation of the part constituting the elevator or garage. Therefore, there is an effect that it is possible to solve the problem that rainwater intrudes into the foundation portion while making the conventional digging work unnecessary.
[0024]
Further, in the present invention, as described above, the floor pallet is installed on the ground surface or the ground via the horizontally movable device having a predetermined degree of friction, and the floor pallet is connected to the seismic isolation building body. The floor pallet can be moved following the seismic isolated building during an earthquake. Therefore, as in the past, there is a special slide allowance for seismic isolation between the seismic isolation building body and the interior car, elevator or installation, or between the seismic isolation building body and a car port provided around the outside. This has the effect that it is not necessary to ensure.
[0025]
In the present invention, when the floor pallet is detachably attached to the base-isolated building body, the floor pallet can be separated from the base-isolated building body and moved as necessary. Therefore, in a parking lot in a small space, etc., the floor pallet is installed in the seismic isolation building body in the same way as a parking pallet that enables parallel parking, such as placing a car on its side and letting it run sideways into the parking space. It has the effect of being able to be used when storing a car or escaping the car.
