Description

[Detailed explanation of the invention] A. Purpose of the invention [Industrial application field] This invention is for floor wiring power lines, information lines, telephone lines, etc. for each equipment in computer rooms, office automation equipment rooms, etc. In addition to floor panels for wiring, this also relates to floor panels that are installed on areas of the floor where wiring is not required, such as locations where bookshelves, lockers, cabinets, etc. are placed, or areas along walls.

[Conventional technology]

A large number of small block groups are formed on the entire surface of a plate made of concrete using split joints, and each small block is connected to each other by a weak joint at the bottom of the split joint on the back side of the plate.
There is also an assembly block plate for floor construction in which a flexible sheet is embedded in the weak joints (for example, Japanese Utility Model Publication No. 57-57153).

[Problems to be solved by the invention] The above-mentioned conventional assembly block plate for floor construction is able to adapt well to the unevenness of the floor due to the bending effect of the plate, even if the construction surface has some unevenness. Although it has the feature of eliminating the need for leveling work, leveling work, etc., it is heavy because each small block is made of concrete.

b. When cracks occur at crack-induced joints, concrete fragments may fall, and the construction surface may be contaminated by the fragments.

c. When a crack occurs at a split-inducing joint, the small blocks are connected to each other only by a flexible sheet, so when carrying the plate, the plate tends to bend, resulting in poor workability.

The present invention provides a floor panel that solves the above-mentioned problems of conventional aggregate block plates for floor construction made of concrete.It is lightweight, has improved workability on exposed concrete floors, and is easy to handle. The purpose is to improve.

B. Structure of the invention [Means for solving the problem] In order to achieve the above-mentioned purpose, the floor panel of the invention has a large number of hollow rigid pieces with open bottoms, which are connected to adjacent pieces. It is characterized in that the pieces are arranged side by side in a plane with a minute gap between them, and the adjacent pieces are connected to each other by integral molding via a thin connection part between the facing sides.

[Effect]

The floor panel of the present invention is laid on the floor with the open side of the pieces facing down, and fixed to the floor using adhesive, mortar, etc. as appropriate. In this case, even if the floor is made of exposed concrete, the floor panel will bend freely, adapt to the unevenness of the floor surface, and adhere tightly to the floor.

Carpet tiles or other finishing materials are placed on the floor panels laid on the floor as described above.

〔Example〕

FIG. 1 is a perspective view of an embodiment of the floor panel of the present invention, and FIG. 2 is an enlarged longitudinal sectional view taken along the line of FIG. 1.

A square floor panel is created by arranging a large number of substantially cubic pieces 1 in a horizontal and vertical plane, leaving minute gaps S between the pieces, and connecting the lower ends of the sides of the pieces 1 with thin connecting parts 2. It constitutes P.
The panel P is set to have a size of 30 to 60 cm on each side.

As shown in FIG. 2, each small piece piece 1 is hollow and its lower surface is open, and the small piece piece 1 and the thin connecting part 2
is integrally molded by die-casting from a lightweight and rigid material, such as aluminum, or by injection molding from a non-flammable/flame-retardant synthetic resin.

The connecting portions 2 between the small piece pieces are made thinner than the wall thickness of the small piece pieces 1, thereby giving flexibility to the connecting portions 2. Therefore, even if the floor is somewhat uneven (concave and convex) due to exposed concrete, etc., the floor panel P will
Since the thin connecting portion 2 can be freely bent, the entire surface of the floor panel P can be brought into close contact with the floor.

The minute gap S between the adjacent pieces 1, 1 may be formed to have the same width above and below as shown in FIG. 2, or may be formed to widen upwardly as shown in FIG. When a small gap that widens upward is provided, the amount of deflection of the floor panel P is large.

In the examples shown in FIGS. 2 and 3, the thin connecting portions 2 between the small pieces are provided at the lower end portions, but as shown in FIG. 4, they may be provided at an intermediate position in the vertical direction of the minute gap S.

Further, the thin connecting portion 2 is provided over the entire surface of the minute gap S, or partially in the form of a band as shown by reference numeral 2A in FIG.

Figure 6 shows the state of floor panel installation, and where it is necessary to wire power lines, telephone lines, information lines, etc., a cross-shaped mark is placed in the center as shown in Figures 9 and 10. A wiring floor panel P1 having a wiring groove 3 and having a top opening of the groove 3 covered by one cross-shaped cover plate 4 is arranged so that the wiring groove 3 is continuously formed in a net shape. The floor panel P of the present invention is placed and fixed in a wall area where there is no need for peripheral wiring or in a position where a bookshelf or the like is placed.

If there is an empty area near a wall where the floor panel cannot fit due to the relationship between the dimensions of the floor and the floor panel, cut the floor panel P of the present invention at the thin connection part 2 at a position that approximately matches the dimensions of the empty area. The rectangular floor panel P2 thus obtained is placed in the empty space.

A plurality of small pieces 1 of the floor panel P of the present invention arranged adjacent to the wiring floor panel P1
is separated and removed from the thin connection part 2 so as to be continuous with the wiring groove of the wiring floor panel P1, thereby forming a recess H, and storing and arranging the outlet, telephone terminal block, and other wiring devices in the recess H. can do.

The upper surface opening of the above-mentioned wiring equipment storage recess H is covered by, for example, fitting a cover C, which is formed into a substantially U-shaped cross section by bending both side edges, into the recess H so that both legs of the cover C are in contact with the floor. Align the top surfaces of the floor panels P.

The above wiring floor panel P1 also has its wiring groove 3.
The other parts except for the floor panel P of the present invention are constituted by a collection of small pieces 1.

Fig. 7 shows a modified example of the floor panel of the present invention, in which the overall size of the panel is the same as that of the example shown in Fig. 1, but the size of each small piece 1 is larger. . A cross-shaped decorative joint 5 is provided on the upper surface of each small piece piece 1 whose upper surface is widened.
As shown in FIG. 8, the joints 5 protrude in the shape of ribs from the ceiling of each piece 1 and serve as reinforcement. The small protrusions 6 formed on the upper surface of the small pieces 1 are for preventing the finishing material such as carpet tiles laid on the floor panel from shifting.

C. Effects of the invention The floor panel of the invention has a large number of hollow rigid pieces with open bottoms arranged side by side in a plane with small gaps between adjacent pieces and connected to each other. Because it is lightweight, it is easy to transport and install, and can withstand heavy loads.

Adjacent pieces are connected by integral molding via thin-walled joints between opposing sides, so the pieces are rigid and will not bend inadvertently during transportation or construction. It is easy to handle because it does not break or chip, and it does not stain the construction floor surface.

Further, as mentioned above, there are minute gaps between the small pieces, and the connecting portions between the small pieces are thin, so that the entire floor panel is flexible. Therefore, even if the construction floor surface is exposed concrete and is uneven (uneven), the floor panel conforms well to the floor surface and can be constructed in close contact with the floor surface.
