Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a seismic isolation floor system using a high damping multi-stage laminated rubber in which a seismic isolation floor using the high damping multi-stage laminated rubber is arranged on a floor slab. Concerned.

[Conventional technology]

FIG. 2 is a diagram showing an example of the installation structure of the high-damping multistage laminated rubber, and FIG. 3 is a diagram showing a configuration example of the air conditioning room space and the computer room space. In the figure, 11 is a high-damping multi-stage laminated rubber, 12 is a concrete frame, 13 is a floor slab, 21 and 26 are computer room spaces, 22 and 23 and 27 are air conditioning room spaces, 2
Reference numerals 4, 25, and 28 indicate air blowing directions.

Computer centers and the like use seismic isolation floors that support high-damped multi-stage laminated rubber on floor slabs to support floor panels. In such seismically isolated floors, the space below the floor panel on the floor slab is used as an air conditioning duct and a duct for wiring. Therefore, the height of the space between the floor slab and floor panel required to use these is determined. To be done. At that time, since the high-damping multi-stage laminated rubber is determined based on the design of the base isolation floor and cannot be increased indefinitely, generally,
There are cases where the required space height cannot be ensured only with the high-damping multistage laminated rubber. In such a case, as shown in FIG. 2, the concrete pedestal 12 is erected on the floor slab 13, and the seismic isolation device made of the high-damping multistage laminated rubber 11 is installed on this. With this, floor slab 1
It is possible to cast the concrete pedestal 12 integrally with the concrete of the floor slab 13 when the concrete 3 is cast.
The workability can be improved accordingly.

Generally, in the computer center plan configured with the above-mentioned seismic isolation floor, as shown in FIG. 3 (a), the air conditioning room space 22 where air conditioners are installed on both sides of the computer room space 21,
23 is provided, an air-conditioning outlet is provided in the wall between the floor slab below the floor panel, and air is sent to the space below the floor panel on the floor slab to provide slits or mesh floors on the floor panel surface. The air is blown upward into the computer room through the air outlet on the panel surface, and conventionally the air distance from the air outlet for air conditioning to the air outlet on the floor panel surface is kept to a maximum of about 15 m.

However, recently, with the heavy equipment of computers, Fig. 3 (b)
In order to secure a large space as the computer room space 26 as shown in FIG. 2, it is considered to adopt a layout in which only the air conditioning room space 27 is provided and one air conditioning room space is eliminated. In this way, the maximum distance in the air blowing direction is 20 to 25 m, so there is a need to increase the air blowing distance. Along with this, securing new air-conditioning space to be used as an air-conditioning duct under the seismically isolated floor is emerging as a new requirement.

[Problems to be solved by the device]

However, as shown in FIG. 2, if the seismic isolation floor is installed by starting up from the floor slab 13 with the concrete stand 12, the concrete stand 12 is used because it is used as an air conditioning space under the seismic isolation floor as an air conditioning duct. There is a problem in that turbulent flow and uneven air-conditioning occur, which prevents air from being evenly sent in the air blowing direction at a maximum distance of 20 to 25 m, resulting in a reduction in air-conditioning efficiency.

Further, in the seismic isolation floor installation method using this concrete pedestal 12, even if the concrete pedestal 12 is placed integrally with the concrete of the floor slab 13, the formwork of the concrete pedestal 12 is placed on the reinforcing bars of the floor slab 13. There is also a drawback that it is necessary to set it, and the formwork work and the reinforcing bar work increase by one process.

The present invention solves the above problems, and provides a seismic isolation floor system using a high-damping multi-stage laminated rubber that secures a sufficient air-conditioning space that does not cause uneven air-conditioning and enables level adjustment of the seismic isolation device. The purpose is.

[Means for Solving the Problems]

To this end, the present invention constructs a seismic isolation floor by launching a high-damping multi-stage laminated rubber on a floor slab and supporting the floor panel. The pipe is erected on the floor slab to support the high-damping multistage laminated rubber.Furthermore, at least one of the high-damping multistage laminated rubber and the floor slab is used as a pipe with at least both ends threaded. The feature is that the screw receiving part is fixed and the pipes are connected so that the level of the seismic isolation floor can be adjusted.

[Action]

In the seismic isolation floor system using the high damping multi-stage laminated rubber of the present invention, since a plurality of pipes are erected on the floor slab to support the high damping multi-stage laminated rubber and the floor panel is supported thereon, the air conditioning unevenness is It is possible to secure a sufficient air conditioning space that does not cause

Also, use a pipe with at least both ends threaded as a pipe, and fix the screw receiving part to at least one of the high damping multi-stage laminated rubber and floor slab to connect the pipes so that the level of the seismic isolated floor can be adjusted. Since it is supported, it is possible to adjust the level of the seismic isolation floor by adjusting the screw engagement.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a view showing the configuration of an embodiment of a base isolation floor system using a high-damping multistage laminated rubber according to the present invention, wherein 1 is a floor panel, 2 is a high-damping multistage laminated rubber, 3 is a pedestal, and 4 is a pedestal.
Is a frame, 5 is expanded metal, 6 is a threaded pipe, 7 is a threaded nut, 8 is a base, and 9 is a floor slab.

In FIG. 1, the threaded pipe 6 is of at least both ends threaded type, and the threaded nut 7 is screwed to the threaded pipe 6 and is welded and fixed to the base 8. Then, the base 8 is bolted to the floor slab 9 as shown in FIG. 1 (b). Further, a threaded nut that is screwed with the threaded pipe 6 is also fixed to the lower end of the high-damping multistage laminated rubber 2.

Therefore, in the high-damping multi-stage laminated rubber 2, the base 8 is bolted to the floor slab 9, the lower end of the threaded pipe 6 is screwed into the threaded nut 7, and the upper end thereof is the bottom surface of the high-damped multi-stage laminated rubber 2. It is installed by screwing it onto a threaded nut fixed to the. By doing so, since only four pipes stand, for example, instead of the concrete pedestal, the air sent out from the air outlet for air conditioning can pass between the pipes without resistance, preventing turbulence and uneven air conditioning. It is possible to secure an air-conditioning space that will serve as an air-conditioning duct for sending air under the seismic isolation floor. Further, unlike the conventional example shown in FIG. 2, it is not necessary to start up the concrete pedestal, so that the process is unnecessary.

Then, a frame 4 is constructed on the high-damping multi-stage laminated rubber 2, a pedestal 3, an expanded metal 5,
A seismic isolated floor can be constructed by attaching the floor panel 1. The expanded metal 5 is to be installed in an area where wiring is required.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, although a threaded pipe is used in the above embodiment, a pipe without threading may be used if level adjustment is not particularly required. Further, although threaded nuts are used at both ends of the pipe, it is needless to say that they may be used for only one. Furthermore, although the four pipes are used to support the high-damping multistage laminated rubber, it goes without saying that the number can be arbitrarily changed according to the strength.

[Effect of device]

As is clear from the above description, according to the present invention, the pipe is erected on the floor slab to support the high-damping multi-stage laminated rubber, so that a sufficient air-conditioning space that does not cause turbulence or air-conditioning unevenness is ensured. You can Moreover, since the concrete pedestal is not necessary, the process can be eliminated. In addition, a pipe with at least one end threaded is used as the pipe, and the screw receiving part is fixed to the high damping multi-stage laminated rubber side and the floor slab and is supported by screwing the screws together. It is possible to adjust the level of.
