PURPOSE:To improve earthquake proof property, and reduce installation space, by fixing the bottom part of a box body which contains an electrical instrument to the floor through the foundation, and at the same time, fixing the upper part to the ceiling through a supporting fixture. CONSTITUTION:The device is formed such that a box body 11 such as a resister, a computer or the like which contain an electrical instruments in the inside is fixed to a base plate 12 with bolts 20, the base plate 12 is installed to the floor with anker bolts 19, furthermore among the upper part of the box body 11 and the ceiling 21, supporting fixtures 22 whose shape are U letter shape are provided at the four corners and the upper part of the box body 11 and the ceiling 21 are connected. Therefore, the structure is the beam supported at both side which is supported at the upper and the lower parts, the strength is reinforced, the earthquake-proof property is improved, and at the same time, since it is not necessary to use an iron column or an iron plate for reinforcement, installation space can be reduced. |
