Description

  The present invention relates to an installation method for installing, on a wall surface, an electrical equipment storage box (hereinafter referred to as a storage box) for storing various electrical equipment such as distribution boards, switchboards, and control boards. .

  Conventionally, as a storage box for storing various types of electrical equipment such as power distribution equipment and communication equipment, a frame is formed by welding angle frames, etc., and a closing plate is attached to each surrounding surface by welding or screwing. There is a frameless structure in which a metal plate is bent and a back plate and side plates are continuously formed, and a top plate and a bottom plate are attached to the metal plate by welding or the like.

However, both the frame-structured storage box and the frameless-structured storage box are shipped in a state of being assembled in a factory or the like, and storage and transportation are performed in the assembled state. Therefore, a large space is required for storage, the efficiency during transportation is poor, and there are problems that many storage boxes cannot be transported at one time.
Therefore, a storage box has been proposed in which a back plate, a top plate, a bottom plate, a side plate, and the like can be assembled at the installation site by screwing or the like (for example, Patent Document 1). With this configuration, each plate can be stacked and stored until it is assembled at the installation site, so the storage space can be reduced and the efficiency during transportation can be improved. There is an advantage that it can be reduced.
