Abstract

PURPOSE: To facilitate the lead-out of a wiring, by providing wiring lead-out ports communicating with wiring grooves in the corners of a floor plate or a composite floor plate. CONSTITUTION: Supporting shelfs 11 are provided in the whole periphery of a floor plate 1, and in the four corners o the floor plate 1, long-semicircle-form engraved holes each of which reaches larger depth than the supporting shelf 11 are so provided as to form wiring lead out ports 2. Such floor plates 1 are so laid on the surface of a floor that their adjacent peripheries are opposed to each other with a wiring groove 3 between them. Between the opposite supporting shelfs 11 to each other, a cover 4 made of a strip-form steel plate is so provided removably as to cover the wiring groove 3, and thereby, the whole surface of the floor comprising the laid floor plates 1 is made flat. A cord 5 laid in the wiring groove 3 in the state of the cover 4 being removed therefrom is drawn out from the wiring lead-out port 2 provided in the corner of the floor plate 1 onto the floor. In this case, it is convenient that the cord 5 is drawn out from the wiring lead-out port 2 present beyond an intersecting portion 31 of the wiring grooves 3, because the cord 5 can be drawn out without bending it in a small radius of curvature. In this way, the cord 5 laid in the wiring groove 3 is prevented from being led out from the side surface of the floor plate 1 while bent orthogonally.

The width is 10 cm, the length is 25 cm, and the height is the same as the floorboard. Is 3 cm. The semi-cylindrical internal space is continuous in the longitudinal direction. A semi-arched notch 62 having a width of 2 cm is provided at both ends of the side surface 61, and an arched notch 62 is provided at the center. At both ends in the longitudinal direction, a reinforcing edge 63 having a width of 1 cm, which is obtained by bending an extension portion of the face plate downward, is attached. Since the reinforcing edge is provided, the width can be as wide as 10 cm even if the half-cylindrical material is formed of a thin plate.

FIG. 6 shows an intersecting half-cylindrical member 6. Similar to the above semi-cylindrical material, it is made by bending a zinc-plated steel sheet having a thickness of 2 mm into a semi-cylindrical shape having a U-shaped cross section with an opening facing downward, and has a width of 10 cm and a length of 30 cm. The height is also 3 cm. Two arch-shaped cross holes 64 are provided in the center of both side surfaces 61. The width of each intersecting hole 64 is 5 cm, the height is 2 cm at the highest point, and a reinforcing column 65 having a width of 2 cm is provided in the center.
