Description

MULTI-FUNCTIONAL MODULE HAVING EARTHQUAKE-RESISTANT AND VIBRATION-PROOF FUNCTION AND ACCESS FLOOR STRUCTURE THEREOF}

The present invention relates to a multi-module having earthquake-proof and anti-vibration performance for protecting electrical and communication equipment such as computers, communication panels, relay panels installed in substations, power generation facilities or various buildings, public and private facilities during an earthquake. More specifically, it can not only maintain the seismic performance in the event of an earthquake, but also maintain the anti-vibration performance, thereby reducing the seismic force on the electrical and communication equipment mounted on the double-floor structure. A multi module with performance.

In general, equipment installed in power supply facilities such as switchboards or relay panels, monitoring panels, distribution panels, communication panels, protection panels, control rooms, communication control lines, control rooms, computer rooms, etc. is to be installed on the floor of a building.

As an example of the prior art documents there is disclosed a registered patent No. 740801. This patent relates to a switchboard in which a panel transformer, a terminal box, a current transformer, and a control unit are incorporated. More specifically, a panel transformer having a plurality of transformers having the same capacity and load characteristics, and a panel transformer made of an auto circuit breaker connecting or separating the transformer from the load, and a low voltage power supply drawn out to the car circuit breaker of the panel transformer. It consists of a terminal box connected to the, a current transformer for detecting the amount of load current flowing in the low-voltage cable, and a control unit for controlling the operation of the automotive circuit breaker by comparing the amount of after-current detected by the current transformer with a predetermined reference data value.

However, this prior art has a problem that the switchboard is installed on the floor of the building, so that deformations may occur in the switchboard due to the impact of the earthquake wave when an earthquake occurs, or various electrical devices built into the switchboard are damaged.

In this case, power cannot be stably supplied to a place where power is required, and there is a problem that safety accidents such as a short circuit and a fire occur.

In order to solve this problem, as shown in FIG.

Referring to Figure 1, first, on the concrete floor slab (2) is a holding rod (3) attached by applying an epoxy adhesive is installed at regular intervals. The stringers 4 are installed in a lattice structure on the support rods 3, the support top plate 1 is installed on the stringer 4, and the switchboard 10 is installed on the support top plate 1.

A shock pad is placed on the surface of the support top plate 1, and the stringers 4 are connected to the holding rods 3 in all directions to fix them with bolts to form a frame. Then, the support top plate 1 is assembled in all directions to fit the impact pad grooves, thereby completing. The material of the support top plate 1 mainly used a steel plate, but recently used a polyurethane and a particle board (Particle Board) integral type that solves the shortcomings of the iron plate.

The overall height of such a conventional double-floor structure is about 20 ~ 40cm, the basic supporting force of the support top plate is 1.5 tons / m ² , the support force is 3.5 tons / m ² when reinforced with a support rod. The switchboard weighs about 100 ~ 800kg and has sufficient support. However, since the basic structure type of the double-floor structure is a ramen structural formula, each corner is not a completely fixed end, so the structure is vulnerable to lateral force or vibration in the event of an earthquake.

In addition, when installing various equipment or equipment inside a building or structure to which seismic design is applied, before installing the double-floor structure, make a steel frame according to the size of the supporting plate of the equipment or equipment such as switchboard, place it in the designated position, and anchor the slab floor. Then, install the supporting floor plate over the remaining space to install and assemble the double-floor structure, and install the control cable to finally assemble the support top plate after the connection work to finish the installation. Therefore, the installation of the conventional double-floor structure according to the size of the floor area of the electrical and communication panel is customized because of the high unit cost, the height is difficult to adjust even during installation, there are many construction restrictions.

On the other hand, as an earthquake countermeasure in the fields where industrial / industrial processing systems such as industrial information processing controllers and OA equipments and related auxiliary equipment are required, especially in high public areas such as electric power, nuclear power, water treatment, aviation, and railway. Not only is the demand for seismic resistance increasing, but also the mandatory seismic measures for all public buildings and facilities are required under the Seismic Disaster Countermeasures Act (No. 9636) and the Enforcement Decree of the Earthquake Disaster Countermeasures Act (Presidential Decree No. 21362). to be.
