An upper layer vertical columnar member 15 made of six single section steels attached horizontally and parallel to the lower layer vertical columnar member 14 at equal intervals, forming a large number of lattice-like voids 16, forming a two-layer structure. It is shaped like a lattice frame. The electric wire cables 10, 11, 12, each having one end connected to the central control panel 5, pass through the floor 3 and enter the laying floor 4, and run inside the laying floor 4 above the lower straight column member 14 and above the upper straight columnar member 14. The vacant space of member 15 was handed over to the left,
The electric wire cable 10.11 is routed downward at a branching point 16m which is the - of the square-chee-shaped space 16, and in the space below the upper layer straight member 15 and between the F layer straight member 14. It curves to the right and to the left, and is bent upwards in suitable further grid-like cavities 16, the other end passing through the floor 3 and being connected to the central control panel 6.7. The electric wire cable 12 is straightly bent downward through the abrasive grid-like cavity 16 (16b), passes through the concrete flat floor 13 and descends, and the other end is connected to the control 99φζ.

The construction work was carried out with great care.

[Problems with background technology]

Generally, the electric wire cable is multi-core and has considerable thickness and rigidity, and when a large number of these 11t wire cables are installed, it is necessary to arrange the wires at branch point iii 16a or other branch point not shown. However, because the electric cables are piled up and jumbled, the wire arrangement becomes a problem, and if you try to forcefully bend and change the installation direction of a large number of 11LIIs cables that are piled up and jumbled, it not only takes a lot of man-hours but also makes the work complicated. There is a risk of damaging the tIII cable due to excessive heat. This causes a prolongation of the construction period of a power plant in which these electric wires and cables are installed, and a decrease in the reliability of its operation.

[Purpose of the invention]

This invention was made in order to solve the problems of the conventional iI#i laying method for electric layer cables. Prevents piles from stacking up and getting mixed up, thereby making installation work easier and reducing work time.
