2. Description of the Related Art Temporary electric power work in conventional construction work will be described with reference to FIG. 3, in which a temporary distribution board 2 and a temporary power board 3 are installed on each floor 1, for example, from an underground temporary substation to a light trunk line 5 and a power trunk line. 6 is laid via the staircase or the shaft 4, and the temporary distribution board 2 and the temporary power board 3 are installed on each floor.
Are connected in series in sequence.

[0003]

However, in the above-mentioned conventional temporary electric power construction, the electric light trunk line 5 and the power trunk line 6 are connected in series to the temporary distribution board 2 and the temporary power board 3 installed on each floor. Therefore, the temporary distribution board 2
As a result of complicated crossing of cables around the temporary power board 3, there is a problem in electric safety management. Also,
There is a problem that the cable processing is complicated at the time of adding each floor, and the work at the time of refilling and the movement of the temporary distribution board / power board becomes a troublesome work, and the work time and cost increase.

The present invention is to solve the above-mentioned problems. By unitizing the temporary power trunk line, the management of electric safety is facilitated, and at the time of cable connection processing or replacement at the time of expansion on each floor. Temporary distribution board of
It is an object of the present invention to provide a unit device for a temporary power main line that can easily move a power board.

[0005]

Therefore, the unit device for a temporary power main line of the present invention has a temporary distribution board 2 and a temporary power board 3 installed on each floor 1 of a building under construction, and a vertical direction of the building. And temporary power lines 5 and 6 laid in
The temporary power trunk line is formed by connecting a plurality of unit cables each having a length corresponding to the floor height.
Is provided with connectors provided at both ends of the cable and a branch portion 10 provided at an intermediate portion of the cable, and the branch portion 10 and the temporary distribution board 2 and the temporary power board 3 are connected by a cable 11 on each floor. It is characterized by It should be noted that the numbers added to the above-mentioned configurations are for comparison with the drawings for facilitating the understanding of the present invention, and the configurations of the present invention are not limited thereby.

[0006]

In the present invention, the unit cable is manufactured and processed in advance, and it is easy to simply connect the connector from the branch portion of the unit cable to the temporary distribution board and the temporary power board on each floor of the building under construction. You can pull in the cable on each floor.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows one embodiment of a unit device for temporary power main line of the present invention, FIG. 1 (A) is a schematic configuration diagram for explaining temporary power construction, and FIG. 1 (B) is a schematic plan view of a unit cable. 2 is a front view showing a mounted state of the unit cable.

In FIG. 1 (A), a temporary distribution board 2 and a temporary power board 3 are installed on each floor 1 of a building under construction.
A temporary power main line such as the power main line 6 is laid via the staircase or the shaft 4. As shown in FIG. 1B, a plurality of unit cables 7 each having a length corresponding to the floor height are connected to the light trunk line 5 and the power trunk line 6, and the unit cables 7 are connected to both ends of the cable by connectors ( It has a female) 8 and a connector (male) 9, and a branch 10 in the middle of the cable. Then, the branch portion 10 of the unit cable 7 is connected to the temporary power distribution board 2 and the temporary power board 3 installed on each floor 1 by the cable 11 on each floor.

In FIG. 2, a branch cable 12 is branched from a trunk line at a branch portion 10 of the unit cable 7, and is connected to each floor cable 11 via a connector 13. A supporting net member 14 having a locking hole 14a is attached to the outer periphery of the unit cable 7 below the branch portion 10, while a hanging member 16 is fixed to the lower surface of the slab 15 and a hanging member is provided. The unit cable 7 is supported by the slab 15 by engaging the hook portions 16 a of the 16 with the engaging holes 14 a of the supporting net member 14. Reference numeral 17 is a connection terminal.

The unit cable 7 having the above structure is
It is manufactured and processed in a factory in advance, and each floor cable 11 can be easily pulled in by simply connecting the connector from the branch portion 10 of the unit cable 7 to the temporary distribution board 2 and the temporary power board 3 on each floor 1. In addition, when the temporary power is added, the unit cable 7 can be easily connected by simply connecting the connector, and the temporary power distribution board and power board can be easily moved at the time of refilling by simply removing the connector. it can.

[0011]

As is apparent from the above description, according to the present invention, by unitizing the temporary power trunk line, it is possible to facilitate the management of electric security as compared with the conventional system. In addition, when connecting cables at the time of expansion on each floor or at the time of refilling and moving temporary distribution boards and power boards,
This can be performed easily and in a short time, the length of the main line cable can be shortened, and the main line unit can be used repeatedly at other sites, so that the total cost can be reduced.
