Description

SEISMIC ISOLATION DEVICE FOR DISTRIBUTION BOARD

The present invention relates to a seismic isolator that effectively absorbs earthquake motion in horizontal and vertical directions to attenuate seismic energy. It relates to a seismic isolator for the entire waterside that prevents breakage, overturning and separation.

With the recent increase in the frequency and intensity of earthquakes around the world, the importance of seismic stability and seismic design of non-structural materials as well as prevention and safety of the building itself is emerging in securing the seismic performance of buildings in preparation for earthquakes.

In particular, if non-structural materials within a structure, such as telecommunications equipment, which are a key element in performing the functions of modern buildings, are damaged due to an earthquake, the disaster prevention function of the building is paralyzed, which is a major obstacle to immediate crisis response for disaster relief, etc. 2 It can cause car damage, so securing the seismic stability of non-structural materials is very important.

For example, in the event of a disaster, damage recovery measures are established on the premise that the electricity supply is stable. Therefore, among the numerous telecommunication facilities in the building, electricity is received into the building, and an appropriate amount of electricity is distributed to each room. Seismic performance is required at the time of design for water distribution panels such as switchboards, motor control boards, switchboards, and distribution boards (hereinafter collectively referred to as 'water distribution boards'), which are the most important in power supply and demand in a building, from control of electric devices.

This water substation requires continuous inspection, repair and maintenance, so it is easy to repair and inspect, and it is a modular cubicle type with high reliability. It consists of a housed structure, and due to its morphological and structural characteristics, it does not move only in the vertical or horizontal direction due to vibrations such as earthquakes, but moves in arbitrary directions such as tilting up, down, left and right. It must be approached differently from seismic design.

Currently, the methods commonly used to improve the seismic performance of the entire waterside are, for example, increasing the strength of the frame or adding braces to increase the lateral strength, and applying the seismic energy from the support to the entire waterside using springs, rubber There are methods such as absorption with devices such as pads, vibrating balls, electromagnets, and ball bearings, and methods of installing isolators to separate the entire water basin from the ground.

However, in the case of a spring, because it attenuates only vertical vibration, it is not suitable for damping the horizontal force in an earthquake. It is not suitable for damping vertical vibrations as it separates the structure from seismic loads.

Accordingly, the conventional technologies applied to the entire waterside attenuate seismic vibration by combining a vibration-proof element that can withstand only vertical rigidity and a vibration-proof element that withstands only horizontal rigidity, but it is difficult to respond immediately to vibration in other directions. As the damping effect is significantly reduced, there is a problem in that the entire waterside is overturned due to the inclination direction.

On the other hand, the entire waterside must satisfy the specific displacement limits suggested by the state and institutions, that is, it must be able to attenuate the horizontal displacement that occurs during earthquakes, so seismic isolators are mainly applied.

These seismic isolators are largely divided into the elastic bearing series using the shear stiffness and damping of rubber, and the sliding bearing series using a friction damping between PTFE (Poly Tetra Fluor Ethylene) and a stainless plate and having a separate restoration device.

In the case of the elastic bearing series, there is a limitation on the proper operating temperature, and there is a problem that the performance is not sufficient due to the change in the characteristics of the rubber in other temperature ranges.

In the case of sliding bearing series, when the structure receives lateral force, the ball supporting it moves freely between the concave sliding surfaces with frictional force, and the damage can be minimized by responding to the damping force by friction and the restoring force by the pendulum motion.

On the other hand, seismic waves can be divided into P-waves, S-waves, and surface waves, Love and Rayleigh waves, which have different speed, amplitude, frequency characteristics, and direction of motion, so the degree of damage to structures is different. do.

However, most of the seismic isolators have a limitation in that the seismic isolating performance is inferior because only vibration components in one direction, up and down or left and right, can be subjected to vibration isolation.

In particular, it is very important to minimize the friction coefficient on the contact surface of the sliding bearing series vibration isolator. Because it may vary depending on

As an example of such a sliding bearing series seismic isolator, Patent Document 1 discloses that a ball caster moves on a rolling plate coupled to the upper end of the coil spring to prevent damage to the structure or the ground when the ground is tilted, and also to dampen the vibration in the horizontal direction. A 'seismic support' is disclosed.

However, since it has a structure in which one coil spring and one ball caster are combined, structural stability is poor when vibration occurs in the horizontal direction, so it is difficult to expect a smooth vibration damping effect.

That is, when the lower structure vibrates in the horizontal direction, it is impossible to form a stable support force because the ball caster moves on a rolling plate coupled to one coil spring.

In addition, in the method of using one coil spring, damping is achieved only when the vibration generated in the horizontal direction is converted to the vertical direction. In order to do this, the spring constant and size must be quite large, so there is a limit in that it is difficult to miniaturize the device.

The main operation and operating principle of the seismic isolator for the entire water substation according to the embodiment of the present invention configured as described above will be described as follows.

6, when a compressive load (vertical load) occurs due to an earthquake or the like in a state installed on the entire lower surface of the waterside, the lower plate 30, the stay 40, the guide block 60, and the casing 80 are excluded. The remaining components move organically, and in this process, the sliding action of the slides 50 and the coil spring 90 can absorb or dampen the vibration and load transmitted to the entire watershed by contracting and extending naturally by dispersing it.

That is, the upper plate 10 and the coupler 20 move in the vertical direction according to the guidance of the stay 40 and the casing 80 , and at the same time the slide 50 slides the stay 40 and the guide block 60 . As it slides vertically along the surface 61, it effectively absorbs compressive load (vertical load) and shear load (horizontal load) to dissipate the energy, thereby suppressing and minimizing the direct transmission of vibrations caused by earthquakes. .

In particular, when the upper plate 10 and the slide 50 generate vertical and horizontal loads due to earthquakes, etc., they can absorb or damp vibrations by appropriately responding to horizontal and vertical displacements while moving up, down, left and right within a certain value, In addition, it is possible to quickly and smoothly return to the original position by the elastic restoring force of the coil spring 90 and stably maintain the overall state of the waterside.

That is, by limiting the horizontal and vertical displacement of the overall waterside due to earthquakes or vibrations to a certain value or less due to the interaction of the upper plate 10 with the slides 50 and the guide block 60, the entire waterside can easily shake or either side By preventing the inclination of the water and minimizing the movement distance, Seismic safety can be greatly improved.

Moreover, since the slides 50 do not move excessively in either direction in the horizontal direction even when they receive an unbalanced load from the upper structure, the vibration duration can be reduced as well as the dispersion effect of vibration can be increased, and when an earthquake occurs, the slide 50 In the course of their operation, the movement speed changes and absorbs vibrations, so they can respond naturally to any direction, such as horizontal or vertical, to flexibly disperse and dissipate the energy.

Not only that, the slide 50 spreads and closes in the left and right directions by the induction action of the bearing bolt 130 more smoothly and adjusts the operating range by itself, as well as the stay 40 and the guide block 60 ) in the process of ascending and descending along the sliding surface 61 of the upper plate 10, the guide block 60, the stopping plate 70, etc., while limiting the displacement by a certain value or more, the vibration energy is absorbed and converted into other energy. By converting it to reduce the magnitude and intensity of vibration, when the overall waterside is distorted in the horizontal direction due to external factors such as earthquakes or vibrations, the distortion is minimized, and the distortion is quickly restored and restored to the original state, and the vibrations throughout the waterside When this is applied, it can be prevented from leaning to either side and can be safely restored to its original state.
