Moving floor for seismic isolation

In order to safely protect computer, electric power, and communication-related equipment placed on the floor of a room from vibration or impact caused by an earthquake or the like, a plurality of movable plates are horizontally installed at a predetermined height by a support frame In which the floor is movable.

In recent years, as a result of frequent occurrence of natural disasters such as earthquakes, it is possible to safely protect various information and communication equipments such as computer equipment, power equipment, and communication equipment, which can be damaged and collapsed easily by vibration or shock caused by earthquake, The movable floor is installed on the floor of the hazardous room.

Such an isolation movable floor comprises a support frame provided at a predetermined interval in the front, rear, left and right sides of the floor, an isolation block provided on the support frame, a support frame interconnecting the support frames, And a movable plate which is continuously installed in close contact with each other.

At this time, when the floor is mounted on the floor, a movable space is provided between the movable plate and the wall so that the movable plate can be seated horizontally by vibration.

However, the displacement space as described above allows the movable plate to be counter-displaced, but exposes the floor as it is, thereby causing the following problems.

In other words, the temperature and humidity are kept constant, so that the information and telecommunication equipments can be stably operated. The wind for constant temperature and humidity is not supplied to the room, but the temperature and humidity are kept constant There is a problem that is difficult to do.

Also, there is a problem that the body of the manager who manages information and communication equipment falls into the displacement space, causing large and small safety accidents. In addition, since foreign matter such as dust existing in the room along with the wind is also introduced into the floor through the displacement space, there is a problem that the seismic block does not operate properly due to foreign matter.

Korean Registered Patent No. 10-1230056, Feb. 15, 2013.

Disclosure of the Invention The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a method of separating a displacement space existing between a movable plate and a wall surface in such a manner that seismic motion of a movable plate is possible, And to prevent a safety accident caused by a foreign object and to prevent a failure of an isolation block due to a foreign object.

The blocking plate is installed at the same height as the movable plate so that a step is not generated between the blocking plate and the movable plate, and the non-moving plate is installed at a height lower than the movable plate by the step difference.

The blocking plate is fixed to the end portion of the movable plate by a fixing member. One end and the other end of the fixing member are vertically bent, one end is connected to the end side of the movable plate, and the other end is connected to the lower surface of the blocking plate A first fixing bolt fixing one end of the connecting piece to the side surface of the movable plate and a second fixing bolt fixing the other end of the connecting plate to the lower surface of the blocking plate.

Wherein the second fixing bolt is formed of a dish bolt having a bolt head so as not to protrude to the upper portion of the blocking plate, a bolt hole through which the dish bolt penetrates is formed in the blocking plate, And a bolt head insertion groove corresponding to the bolt head is formed to be depressed.

And a guide ball is rotatably supported on the other end surface of the blocking plate.

According to the present invention, since the displacement space, which is an empty space existing between the movable plate and the wall surface, is always blocked through the blocking plate regardless of the seismic motion of the movable plate, It is possible to guarantee the operability of the thermo-hygrostat system by eliminating various kinds of conventional clogs and to prevent various safety accidents due to the dropping of the body, and to prevent the abnormal operation of the seismic block due to foreign matters such as cotton There is an effect.

Next, the second strut frame 500 is vertically installed on the floor at a certain distance from the wall surface to support the non-moving plate 600.

That is, the second strut frame 500 supports the movable plate 600 so that the non-movable plate 600 is installed horizontally as the movable plate 400.

At this time, it is preferable that a plurality of the second strut frame 500 are installed at a predetermined interval so as to firmly support the non-moving plate 600 whose number is determined according to the entire length or width of the movable plate 400.

Although not shown, the second support frame 500 may further include a second support frame connected between the second support frame 500 to stably support the load of the movable plate 400.

Next, the non-moving plate 600 is horizontally installed on the upper portion of the second column frame 500.

That is, the non-moving plate 600 is configured to block a certain portion of the displacement region contacting the wall surface among the displacement regions with respect to the wall surface existing for the counter-movement motion of the movable plate 400.

Lastly, the cut-off plate 700 is horizontally installed at the end of the movable plate 400 to block the displacement space which is present for the seismic motion of the movable plate 400.

That is, the blocking plate 700 blocks the remaining portion of the displacement space existing between the movable plate 400 and the non-moving plate 600.

At this time, when the movable plate 400 is not seated in the horizontal direction due to no earthquake or the like, the blocking plate 700 always blocks all the displacement spaces together with the non-moving plate 600, 400 are provided so as to be movable counterclockwise in the horizontal direction.

That is, one end of the blocking plate 700 is fixed to the end of the movable plate 400, and the other end of the blocking plate 700 is mounted on the non-moving plate 600. However, it is preferable that the blocking plate 700 is spaced apart from the wall surface by a distance larger than the seismic distance of the movable plate 400 so as not to collide with the wall surface during the seismic motion of the movable plate 400.

Therefore, the shutoff plate 700 can maintain the temperature and humidity of the room where the constant temperature and humidity system is applied constantly by shutting off the displacement space both when the movable plate 400 is not seated and when it is seated, It is possible to prevent a safety accident caused by the foreign matter and also to prevent the failure of the isolation block due to the foreign substances flowing into the floor.

Here, the blocking plate 700 is preferably fixed to the end of the movable plate 400 by a fixing member 800 as shown in FIG.

However, it is preferable that the second fixing bolt 830 is formed of a plate bolt having a bolt head so as not to protrude from the upper portion of the blocking plate 700. A bolt hole 710 through which the second fixing bolt 830 passes is formed in the blocking plate 700 and a bolt head insertion hole 730 corresponding to the bolt head of the second fixing bolt 830 is formed at the periphery of the bolt hole 710. [ It is preferable that the groove 720 is recessed.

Although not shown, a guide ball may be rotatably supported on the other end surface of the blocking plate 700 contacting the upper surface of the non-moving plate 600.

When the blocking plate 700 is moved in the horizontal direction while counterclockwise moving with the movable plate 400, friction between the upper surface of the non-moving plate 600 and the lower surface of the movable plate 400 is reduced, .

At this time, it is preferable that the guide ball is installed and supported by the retainer which is inserted into the lower surface of the blocking plate 700 so as to freely rotate while projecting downward at a predetermined height on the lower end surface of the blocking plate 700 without step.

As described above, according to the present invention, since the displacement space existing between the movable plate and the wall surface due to the seismic motion of the movable plate is always blocked regardless of the seismic motion of the movable plate, The structural limitations of the seismic movement can be compensated.

The above-described embodiments are merely illustrative, and various modifications may be made by those skilled in the art without departing from the scope of the present invention.
