ている。2. Description of the Related Art In a general office building or the like, a small space called an electric shaft which vertically penetrates a predetermined position of a building body is formed as a facility for distributing power to an office space on each floor. Equipment such as switchboards on each floor is installed inside, and cables spanning each floor are laid.

That is, an electrical shaft is formed by a concrete partition as part of the wall structure of the building. The electric shafts on each floor are in the same position, and wiring holes are formed in the slab between the upper and lower electric shafts. In addition, a window-shaped opening is formed in the partition that divides the electric shaft,
There will also be work to install an inspection door to open and close the opening. After the skeleton work is completed, move to electrical equipment work, install equipment such as a switchboard inside the electric shaft, and perform cable wiring work inside and outside the shaft.

に点検扉を取り付ける付帯作業もある。The above-mentioned conventional general construction work method has some problems as described below. First, in construction work, in order to form a partition with openings for inspection doors, wiring holes, etc. to form an electric shaft (a narrow space extending up and down for electric wiring equipment), a detailed formwork of complicated shape And sleeve installation work is required, and it is a troublesome work despite the fact that it is a small construction work. There is also incidental work to attach an inspection door to the opening of the electric shaft after concrete construction.

覆の損傷などの面で工事品質に不安がともなう。In addition, in the electrical installation work, a narrow space of the electric shaft is entered to install a switchboard and a terminal board to perform wiring work on the same floor and wiring work on upper and lower floors. This on-site work performed on is extremely tedious and time consuming. There is also a problem that the reliability of the finish of electrical wiring equipment depends on the construction technique of the workers on site, and there is concern about the construction quality in terms of maintaining the insulation distance between cables and damage to the cable coating.

Due to the relationship between the progress of construction work in a small space and the work of electrical equipment, there are many situations in which it is difficult for two parties to coordinate the difficult process.

An object of the present invention is to provide an electric shaft unit and an electric equipment construction method using the electric shaft unit.
