Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seismic isolation floor designed to reduce seismic forces acting on computers and the like installed on the floor.

(Conventional technology) Computers are generally installed on raised floors for wiring, piping, air conditioning, etc.; however, the usual method of installing computers is to facilitate loading and unloading and maintenance and inspection. Leave the casters mounted so that it can be moved by hand. ) Stop the rotation of the caster with the stopper. ) Methods such as lifting the caster and attaching another leg are used.

However, in the methods of ) and ), electronic computers are easily moved during earthquakes, resulting in cable breakage. Also, method (2) poses a risk of falling.

For this reason, conventional earthquake countermeasures have been to support computers directly on reinforced concrete floors, or to connect them to supporting hardware on access floors.

In addition, a seismic isolation device is installed on the support metal part,
A floor panel on which a computer is installed is also proposed to prevent large seismic forces from acting on it.

(Problems to be Solved by the Invention) However, the conventional device is a fairly large-scale device and requires a large amount of cost, which has caused delays in earthquake countermeasures.

(Means for Solving the Problems) The present invention was proposed in order to solve the above problems. The seismic isolation floor is separated into a supported lower floor panel and layered so that the upper and lower floor panels can move horizontally independently of each other during an earthquake.

(Function) Since the present invention is configured as described above, in the event of an earthquake, the upper floor panel on which electronic computers, etc. are installed, and the lower floor panel supported on the floor structure via supporting hardware are mutually connected to each other. By independently and relatively moving horizontally, seismic input to important equipment such as electronic computers on the upper floor panels is reduced, and this equipment is prevented from being damaged by earthquakes and is also protected from damage in the event of a major earthquake. It operates without stopping its functions.

(Example) The present invention will be described below with reference to the illustrated embodiments.

1 is an upper floor panel; 2 is a lower floor panel supported on a supporting hardware 3 disposed on a reinforced concrete floor; a ball bearing 5 is mounted on a supporting piece 4 erected on the lower floor panel 2; The upper floor panel 1 is slidably supported through the upper floor panel 1, and an ammunition 6 is interposed between the upper floor panel 1 and the support piece 4.

Since the illustrated embodiment is configured as described above, in the event of a major earthquake, the upper floor panel 1 will be able to move the ball bearing 5 on the support piece 4 erected to the lower floor panel 2 from the lower floor panel 2. They slide against each other through the upper floor panel 1, thereby reducing earthquake input to the computer on the upper floor panel 1, preventing damage to the computer due to an earthquake, and allowing the computer to operate without stopping its functions even in the event of a major earthquake.

The ammunition 6 is stored as the upper and lower floor panels 1 and 2 move relative to each other, and both panels return to their original positions at the end of the earthquake.

Figures 2 and 3 show a seismic isolation floor panel a partially consisting of the above-mentioned upper and lower floor panels in a computer room.
In this example, seismic isolation floor panel a is applied to equipment that is considered necessary from the viewpoint of maintaining functionality of electronic computer b, or equipment that is at risk of falling during a major earthquake, and other parts are By making the size of the seismic isolation floor panel a the same as the conventional floor panel c, the current non-seismic isolation floor can be easily changed to a seismic isolation floor. can do.

In the figure, d is the reinforced concrete floor, e is the floor panel support hardware, f is the gap for moving the seismic isolation floor panel,
g is a protective cover.

(Effects of the Invention) As described above, the seismic isolation floor according to the present invention is separated into an upper floor panel on which a computer etc. are installed, and a lower floor panel supported on the floor frame via supporting hardware, By layering the upper and lower floor panels so that they can move horizontally independently of each other in the event of an earthquake, computers, etc. are protected from earthquakes, and their functions can continue to operate without stopping even in the event of a major earthquake. The upper and lower floor panels make part or all of the raised floor a seismically isolated floor, and by making the size of the floor panel the same as a conventional floor panel, existing non-seismically isolated floors can also be easily isolated. It can be changed to an earthquake bed.
