Description

[Detailed description of the invention] Industrial field of application The present invention provides a method for installing a floor panel made of concrete or the like so that a space necessary for arranging communication cables, power lines, etc. is provided between the floor panel and the floor panel finished with concrete or the like. The present invention relates to a floor member that is installed on a floor to form a floor surface.

Conventional technology and its problems In the past, the floor surface was laid on a floor surface made of concrete or the like so that communication cables, power lines, etc. were provided between the floor surface and a space necessary for arranging communication cables, power lines, etc. The floor members constituting the At the same time, downward notches communicating in the horizontal direction are provided at multiple locations on each leg piece, and if necessary, on the upper surface of the floorboard,
It has a structure in which a facing board such as a carpet is glued.

By the way, according to the above-mentioned configuration, the leg pieces are connected to each other because a communication cable or the like is inserted between them.
It is formed with a relatively narrow width, so it is relatively weak against loads applied in the parallel direction of the leg pieces through the floorboard, and over a long period of time, the leg pieces may deform more or less obliquely from their bases, thereby causing As a result, there are gaps between the floor plates of the installed floor members, which has the disadvantage of spoiling the appearance of the floor surface.

Purpose, Examples, and Effects of the Invention Therefore, the present application proposes a leg piece that is installed vertically on the lower surface of the floorboard.
By creating a mechanically strong V-shaped cross section, the deficiencies of the conventional one have been improved.Examples of this are detailed below with reference to the drawings.
First to third leg pieces 2 having a height of about 32 mm are located at both ends and the middle part of a rectangular floor plate 1 having a length of 166 mm, a length of 500 mm, and a thickness of 5 mm. 3 and 4 are integrally installed vertically, and extend in the longitudinal direction. The first and third leg pieces 2 and 4 located at both ends of the floor plate 1 have a V-shaped cross section with the outer side being vertical and inclined, and the apex thereof is formed in a flat shape. The second leg piece 3 located on the lower surface has a V-shaped cross section with a symmetrical inclination, and its apex is formed in a flat shape, and a non-slip piece 5 is provided on the flat lower surface of each leg piece. are provided in each unit.

Each of the above-mentioned leg pieces 2, 3, and 4 is formed with a hollow portion 6 that penetrates in the longitudinal direction.

The floor member configured in this manner is made of, for example, hard vinyl chloride resin, and the non-slip portion 5
is made from soft vinyl chloride resin, and
The hypotenuses 2a, 3a, 4a of each root portion are preferably curved in an arc shape as shown.

Further, downwardly cut out portions 7 are provided at the same required positions in the longitudinal direction of each of the leg pieces 2, 3, and 4, respectively. Reference numeral 8 denotes a cut groove extending from the lower surface to a part of the floor plate 1, which is provided at three equal positions in the longitudinal direction of the floor member, and 9 is a facing plate, such as an elastic carpet, provided on the surface of the floor plate 1.

Therefore, in use, as in the past, a large number of cutouts 7 are laid on the floor plate A finished with concrete or the like, and the notches 7 are connected between arbitrary leg pieces of each floor member and in a direction orthogonal thereto. A communication cable or the like is placed between the floorboard 1 and the floorboard A, and a relatively small diameter telephone cord or the like is inserted into the hollow part 6 as required.

In the above, it goes without saying that the ratio of the width to the length of the floorboard may be 1:1 or 1:2.

Effects of the Invention As described above, according to the present application, the leg pieces are configured to have a mechanically strong V-shaped cross section and are integrated with the floorboard, so that the leg pieces are inserted in the parallel direction through the floorboard. Even if a large load is applied to the floor, the load will be absorbed by the slanted base and the leg pieces will not deform diagonally. Therefore, even over a long period of time, there will be gaps between the installed floor members. There is no risk of spoiling the appearance, and the hollow part formed in the leg piece reduces weight, and the hollow part can be used as a circulation hole for ventilation, or for passing relatively small diameter electric wires etc. In this case, it is possible to effectively shield the communication cable between the floor plate and the floor plate.According to the present application, the leg piece can be used as a wiring hole from the bottom of the floor plate. By providing a cut groove that reaches a part of the floor, the floor plate has a bending function in the longitudinal direction of the leg piece, which can absorb unevenness between the floor member and the floor plate, preventing rattling. It has the advantage of being able to construct a floor structure with less noise.
