Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional (3-D) seismic isolation module and a seismic isolation device having the three-

The present invention relates to a three-dimensional earthquake-proof module for protecting electrical and communication equipment such as a computer, a communication panel, and a relay panel installed in a substation, a power generating facility or various buildings, public and private facilities in case of an earthquake, Dimensional seismic module capable of stably operating the installed expensive equipment by reducing the seismic force in the vertical direction and the seismic force in the horizontal direction applied to electrical and communication equipment in case of an earthquake.

Seismic forces affecting the buildings in case of earthquakes are different according to the structural characteristics such as the height, shape and material of buildings. Particularly, in the case of electrical and communication equipment installed in the upper part of a high-rise building, seismic force greatly affects the seismic design method of anchoring the electrical and communication equipment to the concrete floor slab.

Especially in areas where public / high power such as power, nuclear power, water treatment, aviation, railway are high, such as industrial information processing control equipment, OA equipment and related facilities, (Law No. 9636) and the Earthquake Disaster Preparedness Act Enforcement Decree (Presidential Decree No. 21362, dated March 25, 2009), all seismic measures for public buildings and facilities In order to achieve the goal. However, when installing an electrical and communication equipment that is highly sensitive to vibration in a high-rise building where high vibration is expected in case of an earthquake, applying the earthquake-resistant design method has a limitation that the precision equipment can endure an earthquake, It is necessary to install electric and communication equipment sensitive to vibration or shock in an earthquake-proof system so as to be continuously operated.

Most of the seismic isolation systems developed so far have been developed by using the LM Guide crossing method, the curved line bearing crossing the rail, the oil damper method, the friction pendulum method, the general bearing method, And the like. This method consists of upper and lower frames to generate relative displacement when vibration occurs due to earthquake, absorbing earthquake energy to prevent vibration. However, the LM guide system is susceptible to conduction or active breakdown of the mounting equipment due to its resistance to the initial behavior at a place where many dusts are generated, and the bearing system can move the mounting equipment stably even during small impacts. There are many problems.

In order to solve such a problem, Registration Practical Utility Model No. 281721 is disclosed as an example of prior art documents. The registered utility model is composed of an upper rubber damping part where the equipment is seated and a lower dustproof part connected to the upper dust damping part, respectively, to reduce vibration transmitted from a vibration source such as an earthquake.

However, this prior art is configured in two dimensions, so that it is possible to reduce vibrations only in the vertical direction among the earthquake motions affecting the devices due to earthquakes, and thus there is a problem in the protection of electric and communication equipment.

Registration Utility Model No. 281721

The rubber elastic body 131b And is inserted into the reinforcement portion 131a to elastically support the support plate 120. The rubber elastic body 131b has a cylindrical shape and preferably has the same shape as the reinforcing portion 131a to be inserted. The vibration absorbing member 131b absorbs vibration in a vertical direction generated from a vibration source such as an earthquake to prevent vibration from being transmitted to the equipment 10 mounted on the support plate 120. In the present invention, 131b. However, the elastic member 131b can be changed to other forms as long as it absorbs vibration in the vertical direction, such as the rubber elastic body 131b.

The adjusting unit 150 includes a moving plate 151, an adjusting bolt 152, and an adjusting nut 153. The moving plate 151 is made of L-shaped steel like the fixing wall 132c and is fixed to the lower surface of the bottom plate 110. The moving plate 151 is made of L-shaped steel, and can be changed into other shapes as well as a c-shaped steel, an H-shaped steel, an I-shaped steel and a T-shaped steel. One end of the adjusting bolt 152 is fixed to the bottom plate 110, and the other end passes through the moving plate 151. The adjusting nut 153 is screwed into the adjusting bolt 152 passing through the moving plate 151. [ The adjusting nut 153 is screwed on the upper surface and the lower surface of the moving plate 151 with the adjusting bolt 152 passing through. Since the height of the bottom plate 150 can be adjusted even if the height of the installed floor is not constant, the adjustment unit 150 can adjust the distance of the bottom plate 110 to the floor, As shown in FIG.
