Description

Earthquake-resistant unit in rack {EARTHQUAKE-RESISTANT APPARATUS OF RACK}

The present invention relates to an earthquake resistant device of a rack, and more particularly, when fixing the top and bottom of a rack (other independent structure), a seismic structure can be implemented at low cost even without a separate structure fall prevention facility and a shock absorbing device. The present invention relates to a seismic device of a rack that flexibly copes with external shock and vibration to protect a structure.

In general, a rack may be referred to as an equipment installation frame structure in which communication equipment, a measuring instrument, a broadcasting equipment, and the like are installed therein to ensure operational efficiency. Such a rack is a facility for increasing the efficiency of work and operation by bringing together the devices constituting the entire system for electronic communication into a system.

As such, the conventional rack can prevent direct impacts (eg, collisions) applied from the outside due to the structure of the steel frame, but uses die-casting made of a rigid metal to withstand its own load. The structure is very vulnerable to the earthquake impact generated from the bottom of the lower surface, and thus, there is a problem that the economic loss due to malfunction, service failure, etc. due to the impact of the structure and equipment mounted inside the structure.

The present invention insulates the ground from the lower sides of the rack, while distributing the load while supporting the displacement (變 位; state or degree of change of the position of the object), the lower earthquake-resistant to provide an independent movement in the event of earthquake movement Way; And an upper seismic means for fixing two upper parts of the rack in a displaced state with respect to the building structure to provide an independent movement when earthquake movements occur, and to reduce the load applied to the lower seismic means. It is done.

According to the present invention, the upper and lower portions of the rack are simultaneously fixed in a displaced state with respect to the building, and the attenuation of the transfer of the earthquake movement to the rack is attenuated through dispersion absorption, thereby maintaining a stable state of the rack against the earthquake movement.

This is attenuated while being delayed in the process.

At this time, the rubber pillar (112a) and the inner / outer spring (112b) (112c) is flexibly shaking in all directions to cope with the displacement, thereby preventing the earthquake movement to act on the rack (1) linearly.

As described above, the attenuated earthquake motion is passed through the iron plate 2 (113c), the insulator 2 (113b), and the rubber plate (2) (113a) of the second support (113) having a symmetrical structure with the first support (111). This buffer protects the rack 1 from earthquake movements.
