DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary power supply system for extending temporary power mains at the time of each floor expansion in a construction work of a building or the like and supplying power from the temporary power mains to a temporary distribution board / power board installed at each floor. The present invention relates to a power trunk unit unit.

[0002]

2. Description of the Related Art Referring to FIG. 3, a temporary electric power work in a conventional construction work will be described. 6 is laid via a staircase or shaft 4, and a temporary distribution board 2 and a temporary power board 3 installed on each floor are provided.
Are sequentially connected in series.

[0003]

However, in the above-mentioned conventional temporary electric power construction, the electric light main line 5 and the power main line 6 are connected in series to the temporary distribution panel 2 and the temporary power panel 3 installed on each floor. The temporary distribution board 2
Also, as a result of the complicated intersection of cables around the temporary power board 3, there is a problem in the management of electric security. Also,
There is a problem that the cable processing is complicated when each floor is added, and the work of moving the temporary distribution board / power board at the time of re-arrangement becomes troublesome, which increases the working time and cost.

[0004] The present invention solves the above-mentioned problems, and makes it easier to manage electric safety by unitizing a temporary power trunk, and also to perform cable connection processing or re-arrangement at the time of each floor expansion. Temporary distribution board
It is an object of the present invention to provide a temporary power trunk unit unit that can easily move a power board.

[0005]

For this purpose, a temporary power main unit unit according to the present invention comprises a temporary power distribution panel 2 and a temporary power panel 3 installed on each floor 1 of a building under construction, and a vertical direction of the building. And temporary power trunks 5 and 6 to be laid in
The temporary power trunk 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. The branch portion 10 is connected to the temporary distribution board 2 and the temporary power panel 3 by each floor cable 11. It is characterized by becoming. The numbers added to the above configuration are for comparison with the drawings to facilitate understanding of the present invention, and the configuration of the present invention is not limited by this.

[0006]

According to the present invention, the unit cables are manufactured and processed in advance, and are simply connected to the temporary power distribution panel and the temporary power panel from the branch of the unit cable at each floor of the building under construction. Each floor cable can be pulled in.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a temporary power trunk unit unit according to the present invention. FIG. 1 (A) is a schematic configuration diagram for explaining temporary power work, and FIG. 1 (B) is a schematic plan view of a unit cable. FIG. 2 is a front view showing an attached 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.
Temporary power trunks such as power trunks 6 are laid via the staircase or shaft 4. As shown in FIG. 1B, the electric light main line 5 and the power main line 6 are formed by connecting a plurality of unit cables 7 each having a length corresponding to a floor height. A female (female) 8 and a connector (male) 9 are provided, and a branch 10 is provided in the middle of the cable. The branch 10 of the unit cable 7 is connected to the temporary power distribution panel 2 and the temporary power panel 3 installed on each floor 1 by each floor cable 11.

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 suspension member 16 is fixed to a lower surface of the slab 15, and a suspension member The unit cable 7 is supported by the slab 15 by engaging the hook portions 16 a of 16 with the engagement holes 14 a of the support net member 14. In addition, 17 is a connection terminal.

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

[0011]

As is apparent from the above description, according to the present invention, the provision of the temporary power trunk unit makes it easier to manage the electric security as compared with the conventional system. In addition, cable connection processing at the time of each floor expansion or re-arrangement and movement of the temporary distribution board / power board,
This can be performed easily and in a short time, and the length of the trunk cable can be shortened. Further, since the trunk unit can be used repeatedly at other sites, the total cost can be reduced.
