Description

[0001] The present invention relates to an earthquake-

The present invention relates to a distribution box having an earthquake-proof structure, and more particularly, to a distribution box having a seismic structure capable of providing seismic performance without changing the existing distribution box structure while providing a complete buffer structure between the building and the distribution box to which the distribution box is fixed.

Generally, the switchboard is installed in the building where the electric facility is installed, and the control and monitoring of electricity are performed by arranging safety devices, instruments, indicators, relays, switches and the like. Such a switchboard usually controls and monitors high-voltage electricity, so it protects the switchboard itself and safely protects the switchboard to prevent accidents caused by the switchboard.

FIG. 1 is a view illustrating a configuration of a conventional distribution box, which includes a main body 10 formed in a box shape and configured to be able to constitute an electric distribution panel therein; And a bracket 20 formed on both sides of the lower portion of the main body and fixed to the floor. By installing the main body on the bracket, the main body is spaced apart from the floor by a predetermined height, thereby preventing leakage due to leakage of water or the like. The main body and the bracket are fastened together by welding or bolts / nuts, while the main body and the bracket are fastened together by installing a door (not shown) in a state that the front surface of the main body is open, .

However, since the main body of the conventional power distribution box is fixed directly to the floor through the bracket, when the earthquake or other large impact occurs, the vibration and impact are directly transmitted to the switchboard. Therefore, when the shock is applied to the switchboard, various internal structures are easily damaged.

Particularly, in recent years, not only earthquakes occur frequently but also the intensity of the earthquakes is gradually increasing. When a building is severely shaken against such an earthquake, a greater impact is transmitted to the switchboard inside the switchboard, thereby increasing the possibility of breakage of the switchboard.

In addition, it can be seen that various structures are collapsing due to natural disasters such as typhoons in recent years as well as the above support. The collapse of such a structure can directly or indirectly impact other neighboring buildings, high portential.

Therefore, a stable earthquake-resistant structure for the switchboard is urgently required due to these problems.

The present invention seeks to provide a distribution box having an earthquake-proof structure that can be installed on the floor of a building to form an electricity distribution board, and to safely protect the power distribution board from earthquakes or other large impacts.

In addition, there is an object to construct an earthquake-proof structure while maintaining the structure of existing distribution board as much as possible.

The present invention relates to an electric distribution box including a pair of brackets provided on both sides of a floor and a body formed in a box shape to be installed on the both side brackets and constituting an electric distribution board therein, A first support piece symmetrically formed on the front and rear sides of the upper surface so as to extend in a direction perpendicular to the side surface, And a second support piece bent downward to face each of the first support pieces at four points on the bottom, A first spring installed in the incision of the bracket and protruding upward through the incision so as to support the bottom of the main body to support the vertical force; And a second spring installed between the facing first and second support pieces to support a horizontal force.

The first and second support pieces are integrally bent from the bracket and the main body through a punching operation.

A fastening piece is formed at an end of the second spring and fastened to the first and second support pieces in a state of being tightly fastened to the first and second support pieces.

And a guard panel fixed to the floor at both sides of the main body and having a cushion pad on the inside facing the main body.

According to the present invention, since the main body is detached from the bracket and is supported by the plurality of springs, when the earthquake or other large impact occurs, the springs buffer the shock to safely protect the switchboard.

3 and 4 are explanatory diagrams showing a main configuration of a distribution box having a seismic resistant structure to which the present invention is applied.
5 and 6 are explanatory diagrams showing another embodiment of a distribution box having a seismic resistant structure to which the present invention is applied.

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

The power distributing box having the earthquake-proof structure according to the present invention includes a bracket 100 formed with a cutter 110 and a first support piece 120, a main body 100 having a second support piece 220 200), a first spring (300) installed in the incision of the bracket to support the bottom of the main body, and a second spring (400) installed between the first and second support pieces.

The bracket 100 is formed as a pair symmetrically installed on both sides of the floor. The bracket 100 has a cross section formed in a 'C' shape, and a cutout 110 penetrating vertically through the front and rear of the upper surface is formed. The first support piece 120 is symmetrically formed so as to be bent so as to be seen in a diagonal direction in a plan view. 3, the bracket 100 can be fastened with an anchor bolt or the like for fixing to the floor through one opened side.

However, it is possible to form more than three points in front of and behind the bracket in consideration of the weight of the switchboard, the distribution box, the elasticity of the first spring to be described later, and the like.

In addition, the first support piece 120 may be formed by bending a metal plate separately and then welding or bolting, but it is preferable that the first support piece 120 is integrally formed from the bracket through a punching operation as shown in the figure.

The main body 200 is formed in a box shape so as to be mounted on the both side brackets 100 and a second supporting piece bent downward to face each of the first supporting pieces at four points of the bottom.

Alternatively, the second support piece 220 may be formed by bending a metal plate and then welding or bolt-fastening it. However, the second support piece 220 may be integrally bent from the main body 200 through a punching operation as shown in the figure desirable.

Meanwhile, the front surface of the main body 200 can be easily inspected and repaired by installing an opening / closing door (not shown) in the opened state, and the inside surface can be closed with an insulating material or a waterproofing material.

The first spring 300 is installed in the incision 110 of the bracket 100 so as to protrude upward through the incision so as to support the bottom of the main body 200 to support the vertical force. That is, the first spring 300 supports the main body 200 in such a state that the bottom of the main body 200 is lifted so as not to touch the bracket 100, thereby supporting the main body from moving up and down from the bracket, Buffer. Therefore, the elastic force of the first spring 300, which is provided in each of the incision openings formed before and after the bracket, must be constant.

The lower end of the first spring 300 is welded to the bottom of the bracket by welding or bolt / nut fastening. The upper end of the first spring 300 is joined to the bottom of the main body by welding or bolt / Tighten with nut to secure.

The second spring 400 is installed between the first and second supporting pieces 120 and 220 to support the horizontal force. That is, the second spring 400 is installed between the first and second support pieces 120 and 220 facing each other in the oblique direction on the plane, thereby supporting the body from the bracket so as not to move back and forth, When it occurs, it cushions forward, backward and leftward and rightward shaking. Therefore, the elastic force of the second spring 400 installed in each of the four directions must be constant.

Both ends of the second spring 400 may be fastened to the first and second brackets by welding or bolts / nuts. At this time, in the latter case, as shown in FIG. 5, a fastening piece 410 is formed at an end of the second spring 400 and tightened with bolts / nuts in tight contact with the first and second support pieces.
