Description

Quake-absorbing device and installation method therefor}

The present invention relates to a vibration absorbing device and a method of installing the vibration absorbing device.

For example, Japanese Unexamined Patent Application Publication No. 2000-14472 discloses an up and down curved rail between an upper base fixed to a vibration absorbing object and a lower base fixed to a floor surface, and a roller that rolls the rail at an angle of about 90 degrees. A vibration absorbing device is described, which is arranged by arranging a well in a shape of a well.

In this conventional vibration absorbing device, when the roller raises the rail by vibration in the left and right direction and absorbs the vibration in the left and right direction, the roller lowers the rail by its own weight (a load to be subjected to vibration absorption, etc.). The vibration (earthquake vibration, etc.) is absorbed and attenuated by the movement displacement of the vertical movement of the roller.

However, in the case where computer-related equipment such as a server becomes a vibration absorbing object, wiring facilities such as communication and electric circuits, which extend from the floor surface, are often connected to the vibration absorbing object. In this situation, the wiring equipment was inserted between the rail and the roller.

Therefore, even when the conventional vibration absorber is used for the vibration absorbing object to which the wiring facility is connected, there is a high possibility that the wiring facility will come into contact with the left and right moving ranges of the vibration absorbing device, and the vibration absorbing performance may be reduced. In many cases it was not available. In addition, since the rails and the rollers are fixedly arranged in a two-stage structure, the installation space between the vibration absorbing object and the floor surface becomes large, and there is a problem that it is difficult to install wiring equipment using this installation space. In addition, there are similar problems in cable wiring such as lighting even in exhibition stands such as works of art.

In addition, when a conventional vibration absorbing device is to be installed on an already installed vibration absorbing object, the operation of the vibration absorbing object should be temporarily stopped, and the wiring facility must be disconnected once, and then the wiring facility must be reconnected after the vibration absorbing device is installed. There is a problem.

Therefore, it is difficult to add a vibration absorbing device later to the vibration absorbing object already installed, and the current situation is that the actual vibration absorbing object is firmly fixed to the floor using an anchor or the like.

However, in vibration such as earthquake vibration, there is a limit to firmly fix the vibration absorbing object to prevent conduction, and therefore it is urgent to install a vibration absorbing device that absorbs and attenuates the vibration.

In addition, since the roller rolls up and down the rail in the left and right direction, the seismic vibration is absorbed and attenuated. Therefore, in order to sufficiently exhibit the vibration absorbing performance, it is necessary to secure the rolling distance of the roller and require a required rail length. . Therefore, the external dimensions of the vibration absorbing device are limited to the rail length, and it is difficult to design an external dimension smaller than the dimension satisfying the rail length of the two rails, and there is a shortage in generality.

The present invention has been made in view of the above problems, and exhibits stable vibration absorbing performance with respect to the vibration absorbing object to which the wiring facility is connected, and does not stop the operation of the vibration absorbing object with respect to the vibration absorbing object already installed. An object of the present invention is to provide a vibration absorbing device and a method of installing the vibration absorbing device which can install the vibration absorbing device.

In order to solve the above problems, the method for installing the vibration absorbing device and the vibration absorbing device of the present invention is characterized by providing an insertion passage area through which wiring equipment connected to the vibration object can be inserted.

In the event of an earthquake, it is possible for the wiring facility to exhibit stable vibration absorption performance without contacting the vibration absorption device.

Then, the vibration absorbing units 111 and 112 are connected to the connection members 121 and 122 to form the vibration absorbing apparatus 100. At this time, the distance between the mall 1 of each of the vibration absorbing units (111, 112) is W16, the distance between the lower stand 2 is W17, the vibration absorbing units (111, 112) and the connecting members 121, If the opening areas of the openings 7a and 7b surrounded by 122 are K1 and K2, then K1 <K2.

Next, the installation method of the vibration absorbing device 100 will be described with reference to FIG. 9.

First, as shown in Fig. 9A, the vibration absorbing object P is connected to a wiring facility C which extends from the floor surface F. A lifting device such as a claw jack 150 having a claw 151 is provided on both sides of the vibration absorbing object P installed in the state shown in FIG. 9 (a). Here, the toe jack 150 is employed as the lifting device, but the object is to lift the vibration absorbing object P from the floor surface F to provide a vertical gap Y. Therefore, the vibration absorbing object ( The upper and lower gaps Y may be raised by lifting P), and the lifting device and the like are not limited.

Then, the vibration absorbing object (P) is upright by the jack 150, the vertical gap (Y) for inserting the vibration absorbing units (111, 112), that is, the vibration absorbing unit 111 and the vibration absorbing unit ( An upper and lower gap Y larger than the height W of 112 is ensured. If the upper and lower gap Y is secured, the temporary support stand 160 is inserted into the upper and lower gap Y, and is installed near the wiring facility C to stably support the vibration absorbing object P, The toenail jack 150 is removed (FIG. 9 (b)).

The vibration absorbing unit 111 is inserted into the vertical gap Y supported by the temporary receiving stand 160. The vibration absorbing unit 111 is provided so that the end P1 of the vibration absorbing object P becomes near the center of the mall 1 (FIG. 9 (c)). Next, the vibration absorbing unit 112 is similarly equipped so that the end P2 of the vibration absorbing object P is approximately near the center of the mall 1 (Fig. 9 (d)). The vibration absorbing units 111 and 112 provided in this way form an insertion passage portion Z of the wiring facility C, without contacting the wiring facility C, to facilitate the vibration absorbing object P. FIG. It is possible to be equipped, the wiring arrangement (C) is arranged in the insertion passage (Z) formed by combining the vibration absorbing units (111 and 112).

When the installation of the vibration absorbing units 111 and 112 is completed, the temporary support stand 160 is removed. For dismantling the temporary support base 160, toenail jack 150 used to lift the vibration absorbing object (P) is used. The toenail 151 is provided at the base of the vibration absorbing object P adjacent to, for example, the vibration absorbing units 111 and 112 except for the places where the vibration absorbing units 111 and 112 are provided, and the toe jack 150 is provided. Install). After the vibration absorbing object P is stably supported by the claw jack 150, the temporary support base 160 is removed from the vertical gap Y (Fig. 9 (e)).

If the temporary support base 160 is dismantled, the last positioning adjustment is performed to accurately position the vibration absorbing units 111 and 112 at a predetermined position. Then, by the claw jack 150, the vibration absorbing object (P) is slowly lowered, and the vibration absorbing object (P) is mounted on the upper surface of each mall 1 of the vibration absorbing units (111, 112). (FIG. 9 (f)).

It is confirmed that the vibration absorbing object P is stably installed in the vibration absorbing units 111 and 112, and the connecting members 121 and 122 are mounted on the mall 1 and the lower stand of the vibration absorbing units 111 and 112. In connection with each of (2), the installation of the vibration absorbing apparatus 100 is completed (FIG. 9 (g)).

The vibration absorption operation in the earthquake vibration and the like of the installed vibration absorption device 100 will be described.

As shown in FIG. 6, in the first rails 3a and 3b extending linearly in the horizontal direction and curved in the vertical direction, the first rollers 5a and 5b are approximately the center portion 30a of the first rail 3. ). At this time, for example, as shown in FIG. 8, when the floor surface F moves in the D direction due to an earthquake vibration or the like, each of the vibration absorbing objects P mounted thereon is connected to the connecting member 121. The mall 1 moves in the E direction.

The first rails 3a and 3b provided to the mall 1 are rotated or slipped on the first rollers 5a and 5b as the floor surface F moves in the D direction, thereby providing a rail. The movement starts so that the end part 30c is located in the first rollers 5a and 5b. The first rollers 5a and 5b have a stroke length (approximately 1/2 of the rail length) in the range from the central portion 30a to the end portion 30c. Therefore, the vibration absorbing object P also moves the distance (1/2) x W12 horizontally to E direction horizontally by the 1st rail 3 which rolls in E direction.

For example, the first rail 3a rolls on the first roller 5a in the E direction at the amplitude of the maximum stroke length. At that time, the 1st rail 3a rolls and moves to the one end part 30c on the 1st roller 5a. Thereafter, the first rail 3a starts to move in the D direction, and the first rails 3a and 3b are positioned such that the first rollers 5a and 5b are positioned near the other ends 30b. Move. Therefore, in response to the vibration in the left and right directions, the first rail 3 is lifted on the first roller 5 by the curved portion, and the vibration in the left and right directions is lost, and the first rail 3 is self-weighted (vibration). Drop by the load or the like of the absorbent object P). The vibration in the left and right directions is absorbed and attenuated by the vertical displacement of the first rail 3.

Moreover, the positional relationship of the 1st rail 3 and the 1st roller 5 is reversed in the 2nd rail 4 and the 2nd roller 6, and the movement of a vertical movement of the 2nd roller 6 is carried out. The vibration in the left and right directions is absorbed and attenuated.

According to the first embodiment, the vibration absorbing units 111 and 112 are combined such that the insertion passage portion Z through which the wiring facility C is inserted is formed in the vertical direction of the center of the vibration absorbing object P. FIG. It is arrange | positioned, and is installed around the wiring installation C in the vertical clearance Y between the vibration absorption object P and the floor surface F raised from the floor surface F. As shown in FIG. Therefore, since the wiring installation C is inserted and passed through the insertion-passing part Z by a combination, the later addition arrangement | positioning to the vibration absorption target P already installed is attained. Therefore, the vibration absorbing apparatus 100 separates the wiring facility C once from the already installed vibration absorbing object P to which the wiring facility C is connected, without stopping the operation of the vibration absorbing object P. It is possible to provide a vibration absorbing device that can be installed on the vibration absorbing object (P), so that the connecting members 121 and 122 are connected to each of the vibration absorbing units after the vibration absorbing units 111 and 112 are disposed. It does not interfere with wiring facility (C).

In addition, each of the vibration absorbing units (111, 112) divided by the vibration absorbing device is provided with a pair of the first rail (3) and the first roller (5), and the orthogonal to the first rail (3) Two pairs of the second rail 4 and the second roller 6 to be arranged are provided, and as shown in FIG. 4, the mall 1 is formed with a long side W11 and a short side W12, as shown in FIG. 4. Since the length of the installation direction (short side 12 direction) in which (3) is installed is short with respect to the length of the installation direction (long side 11 direction) in which the said 2nd rail 4 is equipped, unitization of a vibration absorption apparatus is carried out. It is possible to provide a vibration absorbing device having high versatility with respect to the vibration absorbing object P regardless of whether it is newly installed or newly installed.

Since each of the facility intervals W16 and W17 of the vibration absorbing units 111 and 112 are independent, by adopting a variety of long and short connecting material 120 according to the shape, size, and installation of the vibration absorbing object (P) Also, various vibration absorbing objects P can be appropriately installed, and thus the vibration absorbing device 100 which does not depend on newly installed or already installed vibration absorbing objects P can be provided.

For example, as shown in FIG. 10, when a plurality of vibration absorbing objects P are already installed in parallel, one vibration absorbing unit 110 is disposed at two vibration absorbing objects P. FIG. . Conventionally, one vibration absorbing device is installed for one vibration absorbing object P. However, if three vibration absorbing units 110 are disposed for two vibration absorbing objects P, the number of the vibration absorbing units 110 is reduced. The cost reduction of the vibration absorbing apparatus 100 is promoted. Also, by changing the length of the connecting member 120, the distance between the vibration absorbing units 110 (the area of the insertion passage portion Z) can be freely adjusted and the plurality of vibration absorbing units 110 can be set to 1. It is also possible to connect with two connecting members (120).

Since the vibration absorbing apparatus 100 is composed of unitized vibration absorbing units 111 and 112 and connecting members 121 and 122, the respective weights of the vibration absorbing units 110 themselves are reduced, and thus the transport and carry-in are carried out. It is effective to reduce the cost of carrying and carrying out by carrying out smoothly and the like.

Since the opening 7b of the lower stand 2 has an opening area larger than the opening 7a of the upper stand 1, the region of the insertion passage portion Z on the floor surface F is a vibration absorbing object. It becomes larger than the area | region of the insertion part Z of the side (P). Therefore, the overlapping area with the opening 7b of the lower stand 2 when the upper stand 1 moves during the vibration absorbing operation becomes large, thereby interfering with the wiring facility C connected to the vibration absorbing object P. There is no work.

Since each of the vibration absorbing units 111 and 112 is connected to the mall 1 and the cradle 2, in particular, the work to be added later is facilitated. In addition, since the connecting member 120 is connected to the side surfaces of the mall 1 and the bottom 2, it facilitates the installation work of the connecting member 120, and at the same time stable vibration absorption without lowering the vibration absorption operation It is possible to exert.

In addition, the vibration absorbing unit 110 does not need to be fixed to the vibration absorbing object P and the floor surface F, and thus the vertical gap Y between the vibration absorbing object P and the floor surface F lifted from the floor surface. In the periphery of the wiring facility C and the like, the vibration absorbing object P and the floor surface F are independent. Therefore, it does not depend on the installation situation.

In addition, in the operation of absorption and attenuation of the vibration energy, since the first rail 3 is reinforcemently attached to the mall 1 that is in contact with the vibration absorbing object P, the seismic strength is increased to prevent torsional deformation. . Therefore, the effective vibration absorption function is effective for a long time.

11 and 12 show Embodiment 2 according to the present invention.

In this Embodiment 2, before inserting the vibration absorbing unit 110 into the vertical gap Y, the plurality of vibration absorbing units 110 of Embodiment 1 described above are combined at intervals into which the wiring facility C can be introduced. Place them side by side. By connecting each side 131 of one side of the plurality of vibration absorbing units 110 juxtaposed such that the insertion passage portion Z is formed with the connecting member 120, the combinations are formed in a substantially U shape, and the connecting member 120 A plurality of vibration absorbing units 110 are inserted into the vertical gap Y from the side surface 132 on the other side not connected to each other. In addition, the vibration absorption unit 110, the connection member 120, and all other configurations are the same as in the first embodiment described above.

In the vibration absorbing apparatus 100 of the second embodiment, the positional relationship between the plurality of vibration absorbing units 110 and the wiring equipment C becomes clear, and the position can be adjusted in advance so as not to interfere with the wiring equipment C. Since the vibration absorbing unit 110 is easily arranged, a plurality of insertion passages Z are formed in advance in correspondence to the vibration absorbing object P to which the plurality of wiring facilities C are connected.
