Description of the Related Art Conventionally, the most widely spread and practically applied technology for building earthquake countermeasures is a method called seismic resistance that resists seismic force due to the structure of the building. There is a rigid structure type. The seismic method is
It is intended to prevent the collapse of the building due to the seismic force, and humans and objects in the building are directly affected by the earthquake, so they could not escape the primary or secondary damage of the earthquake.

Therefore, the floor of a building having an earthquake-resistant structure has an independent double-floor structure which is separate from the building frame, and the independent double-floor is arranged on the foundation of the floor through a displacement mechanism such as rubber. , A seismic isolation double floor that is designed to escape or absorb and reduce the seismic force applied to the building has been proposed and put into practical use.

The seismic isolation double floor prevents the collapse of the building from being transmitted to the floor on which humans and articles are placed, while preventing the collapse due to the earthquake by making the building itself a seismic resistant structure and preventing the humans and articles in the building from being affected by the earthquake. Since it is possible to avoid the primary or secondary damage, and only the floor in the building of the earthquake-resistant structure can be made a floor separate from the building frame, and a structure corresponding to the seismic force can be provided. , It has the advantage that only the floor of the existing building can be renovated and constructed.

The floor panel is placed on the panel support plate while fitting the engaging projections and the engaging recesses, and is connected by the connecting screws to construct a double floor. The periphery of the double floor is terminated at a distance from the walls and columns of the building frame, and the gap is horizontally displaced and closed vertically by a sealing panel that is free. When a seismic force is applied, the elastic legs of the support column bends in response to horizontal shaking and expands and contracts in response to vertical shaking, reducing seismic force. Since the periphery of the double floor is separated from the walls and columns, the double floor is separated from the building frame and the seismic force is blocked.

By fitting the engaging projection and the engaging recess, the panel support plate and the floor panel integrally resist the force in the horizontal direction, so that the entire double floor is operated integrally. .
Further, since the entire double floor is integrated in this way, it becomes easy to flatten the floor surface by adjusting the height of the panel support plate.

According to the present invention, a floor panel can be placed directly on the upper part of a column to construct a double floor, and the elastic members thereof can be individually reduced, so that the double floor is removed from the foundation floor. The height can be made extremely small compared to the case where joists are used, and when installed in an existing building, the indoor height can be made sufficiently large, so of course not only for new buildings. Therefore, it can be applied to existing buildings without any problems.

Since the connection between the panel support plate and the floor panel is strong and stable and is supported by the elastic body, even when an earthquake force is applied, the earthquake force is absorbed and reduced to reduce the damage to the person or property on the double floor. Eliminates the risk of primary or secondary damage to.

Since the wiring outlet can be easily created, the wiring can be easily taken out.

Place a smoke hood close to the smoking area,
Since the air can be exhausted under the double floor, the room can be kept clean, and the surface of the space under the double floor and the inner wall surface of the floor panel itself with side holes are used as the adsorption and removal surface for nicotine and tar. It becomes possible to do.
