Technical Field

[0001] The present invention relates to a temporary box.

Background Art

[0002] Generally, a temporary box is mainly installed on scaffolds at construction sites such as construction sites, building sites, and work sites, and is temporarily used when necessary. A temporary box is a container for storing construction equipment, and is a box for temporarily storing electric equipment such as generators and compressors and tools used at construction sites. Conventionally, when temporary power is required, a temporary power pole for the lead-in wire is erected at a construction site such as a building site, and a temporary box is arranged to secure a power source.

[0003] On the other hand, lighting fixtures are widely used not only for indoor lighting of general buildings such as detached houses and offices, but also for indoor lighting of special buildings such as schools, gymnasiums, hospitals, theaters, exhibition halls, department stores, factories, and warehouses, as well as for outdoor street lights and work lights at work sites. Work lights are used as lights at work sites outdoors, such as road construction and tunnel cutting work at night, and illuminate the surrounding area of the work site. Work lights are generally referred to as work lights, floodlights, etc. Work lights are lit by receiving power supply such as AC100V, 200V, or three-phase alternating current, which is a commercial power source. Many products have a large light output, high waterproofness, and high durability, and are used not only for work at construction sites outdoors and indoors, but also for lighting of buildings and exhibits.

[0004] So far, at a construction site, a temporary box for storing necessary construction equipment and storing tools for efficiently proceeding with construction during the construction period has been proposed (Patent Document 1). In addition, a device has been developed in which a pair of support members are provided vertically in a manner of being erected on a pair of columns of a portal frame member, and a casing of a distribution board device (so-called temporary box) is connected and fixed from the back side (Patent Document 2).
