Description

{Seismic Access Floor System Installed by Non-Anchoring Method}

The present invention relates to an earthquake-resistant flooring for installation of electrical and communication facilities, and more particularly, to a floor-standing structure for installation of electrical and communication facilities, and more particularly to a floor- H-beams, and after installing a seismic steel lattice plate, a wood top plate is finally installed thereon. In the event of an earthquake, it is possible to support vertical and horizontal vibrations in the support frame part and the compression device, And to protect the floor surface of the building. The present invention relates to a non-anchoring indirect fusing type earthquake-resistant floors.

Generally, electrical and communication equipment such as computers, communication panels, relay panels, etc. are mounted in special facilities such as substations and power plants, and various public and private facilities. Of these, electrical and communication equipment are often installed at the upper level of high-rise buildings.

The magnitude of the seismic force affecting the buildings in the event of an earthquake varies depending on the structural characteristics such as height, shape and material of the building, and affects electrical and communication equipment installed in the building. Especially, in case of telecommunication equipments installed in the upper part of the high - rise building, the seismic force works more because of the height of the building.

According to the Earthquake Disaster Countermeasures Act (Law No. 9636) and the Earthquake Disaster Countermeasures Enforcement Decree (enacted on March 25, 2009, Presidential Decree No. 21362), earthquake countermeasures are mandatory for all public buildings and facilities. The demand for earthquake resistance is increasing even in areas with high publicity such as facilities, water treatment, aviation, and railroad.

Particularly, there is a desperate need for countermeasures against such vibration resistance in a field in which real-time processing is required on-line, such as an industrial information processing control device, an OA device, and an associated auxiliary equipment.

However, since the earthquake-resistant design method of generally used electric and communication equipments is such that these equipments are fixed to an concrete floor slab of a building or a facility by an anchor, there is a problem that the anchoring work damages the floor surface of the building.

Especially, in the case of leased buildings, due to the problem of damaging the floor surface, it is impossible to construct such anchoring, so that it is impossible to install the facility for the seismic reinforcement of the system.

A dual floor module equipped with a three-dimensional earthquake isolator disclosed in Japanese Patent No. 10-1419308 includes a first frame, a second frame coupled to the upper side of the first frame, and a second frame coupled to the lower side of the first frame, And a vertical direction earthquake isolator provided between the first frame and the second frame for attenuating vertical seismic force. However, the structure is complicated and general electric and communication equipment is installed There is a problem of overcapacity due to high construction cost.
