There is a problem in that it is necessary to open the line hole 18, and it takes a lot of time to process the hole in the floor 2b. In addition, the total wiring length becomes long for the plurality of wall outlets 8f, 8f. That is, conventionally, since the individual wirings 32 in the partition wall 4 are laid out under the floor, the length of the entire wiring from each wall outlet 8f, 8f to the underfloor wiring 30 becomes long, and there is a problem that wiring loss occurs. . Further, when the number of the through holes 18 on the floor 2b is large during the maintenance of the wiring, especially when the layout of the wiring equipment is changed or reformed, the through holes 18 are repaired or a new through hole 18 is drilled by that amount. There is also a problem that it is troublesome and that wiring mistakes easily occur due to wiring under the floor.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to reduce the number of through-holes on the floor floor and to eliminate wiring loss and wiring mistakes. The objective is to provide an effective partition wall wiring structure that can realize the rationalization of construction work and can easily respond to changes in the position of wiring equipment.In addition, it is easy to maintain the wiring while improving the aesthetics of the room.

The floor 2b is provided with a partition wall rail 9 having a substantially U-shaped cross section along the lower surface of the partition wall 4, and the partition wall 4 has a plurality of rails 9 for partition walls at the lower end surface thereof. A leg portion 15 having an inverted T-shaped cross section that is fitted into the rail 9 is provided in a protruding manner, and the leg portion 15 extends laterally between the lower end surface of the partition wall 4 and the rail 9 for the partition wall. A passage 16 is formed. An end hole 1 opened vertically is provided near the end 9a in the longitudinal direction of the partition wall rail 9.
8 ′ is provided, and the floor floor 2 b is provided with a through hole 18 that faces the end hole 18 ′, and the underfloor wiring 30 inside the double floor 2 is provided from the through hole 18 to the end portion. Hole 18 '
It is adapted to be drawn into the under-wall wiring passage 16 via the.

The end hole 1 in the under-wall wiring passage 16 is also provided.
A joint box 17 is installed near 8 ', and the underfloor wiring 30 and the wiring 32 in the partition wall 4 are connected via the joint box 17, and further, FIG.
