Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial field of application The present invention relates to a wiring floor having improved stability by dealing with unevenness (unevenness) on the upper surface of a floor slab.

2. Description of the Related Art Conventionally, a floor material for wiring is large in one unit when it comes to wiring floors, and in particular, the board material must be thickened so as to have strength when the board material is formed of a material such as GRC and a calcareous plate. A thin, but strong metal board material such as aluminum or iron is often used, and a four-point-supported floor in which legs of the same size are fixed near the four corners of the lower surface of the square board material. Although a floor material is formed, it is easy to place and install on the floor slab upper surface in such a floor material, but long ribs (reinforcing material) are fixed to the back surface of the board material to maintain strength against central concentrated load. Therefore, it is necessary to increase the rib height in order to give the above ribs strength. Therefore, the wiring space between the upper surface of the floor slab and the board material is narrowed, and the height of the upper surface of the board material with respect to the floor slab is reduced. When done,
It has a drawback that the wiring space becomes narrower.

Furthermore, since one floor is large and supports four points at a time, it is often the case that one leg cannot touch the floor slab due to unevenness (unevenness) on the top surface of the floor slab. It has the drawback that it becomes unstable and eventually even the one placed on the floor material becomes unstable.

There is also a part of a three-point-supporting floor material in which the board material is formed in a triangular shape and leg portions of the same size are fixed near the three corners of the lower surface of the board material. The three-point support increases stability, but the number of boards is large due to the triangular board material. Moreover, two floor materials should be placed while positioning so as to form an accurate square shape. However, it has a drawback that it is difficult to lay it on the upper surface of the floor slab.

Further, in the claims of Japanese Patent Application Laid-Open No. 1-280166, which was published before the present application, "a panel body having a rectangular planar shape is divided into a plurality of small sections, and a boundary portion between the respective small sections is provided. The floor panel is configured by forming a bending permitting portion that enables relative swinging of both small compartments located on both sides of the boundary portion, and further by projecting support feet at the back side corners of each small compartment. . ", But since bending portions of the panel body are formed in the entire boundary portion or at a plurality of positions as bending-allowing portions in FIGS. Only the relative swinging of the two small sections located on both sides of the panel main body, the corners of the small sections on the center side of the panel body are always in the same position, and there is a drawback that it is not possible to cope with the unevenness of the top surface of the floor slab that is rich in changes. In addition, since the floor panels are laid without forming any gaps between them, all the relevant parts should be covered during wiring work. Has the disadvantage that the floor material must be removed, and because the floor materials are not interconnected and the integrity of the floor materials is poor, each floor material moves independently due to vibration or shock such as an earthquake. The wiring floor made of such a floor material has a drawback that it easily collapses.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to provide a wiring floor which is easy to lay on the upper surface of the floor slab and is always stable regardless of unevenness (irregularities) of the floor slab. Is.

[Constitution of device]

Means for Solving the Problems In order to solve the above-mentioned drawbacks, the present invention lays a large number of floor materials with a gap for wiring provided between them, and a cover member is placed in the gap to provide a floor material. In the wiring floor in which the fitting insertion portion of the cover body is inserted into the insertion insertion hole formed in the stepped portion provided at the peripheral portion of the wiring board, the floor material is a cross-shaped cut on the diagonal of the square board material. And the four corners of the board material on the end side of the cut portion are made extremely thin, and the support legs are vertically provided at the three corners of the board member divided by the cut portion. Since the connecting portion between the floor members is only one extremely thin portion on the end side of the cut portion, each floor member can be swung up and down with the extremely thin portion as a fulcrum, and with respect to an adjacent floor member. Swingable, the floor material corresponds to the unevenness (unevenness) of the floor slab, and also the board Since the member itself is a small piece, it has a necessary strength even if it is thin, so that the space below the floor member is widened.
