BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring floor panel called a free access floor.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 5-39143 has been known as a wiring floor panel. This fair 5
In the conventional example disclosed in Japanese Patent No. 39143, as shown in FIG. 7, a floor panel 1 having a square shape in a plan view is vertically and horizontally divided into 3 rows and 3 columns, each of which is divided into nine block bodies 2. The wiring groove 3 is formed in a cross shape so that the center of the wiring becomes an intersection. Then, the conventional floor panel 1 having a square shape in plan view (for example, 500 mm × 500 mm)
Are arranged as shown in FIG. 8 to form a wiring floor A. In the wiring floor A thus formed, the wiring grooves 3 are continuously formed to form a grid-shaped wiring groove 3 group. Of.

The grid-shaped wiring groove groups 3 formed as described above are adjacent to each other in the vertical and horizontal directions.
Two block bodies 2 having no wiring groove 3 are interposed therebetween. That is, the pitch of the wiring grooves 3 in both the vertical and horizontal directions is one side of the square wiring floor panel 1 (for example, 500 m).
The pitch is the same as the length of m). Reference numeral 8 in FIG. 7 denotes a lid that covers the wiring groove 3. FIG. 8 shows a state in which the lid 8 is removed when a plurality of floor panels 1 are arranged vertically and horizontally to form the wiring floor A.

[0004]

However, in recent years, a higher floor finish height has been required from the viewpoint of securing a living space. Therefore, as in the conventional case, the floor has a square shape in plan view and the center of the square intersects with the intersection. In the case where the wiring grooves 3 are formed in a cross shape so that, when these are arranged vertically and horizontally, there are two block bodies 2 that do not have the wiring grooves 3 between the adjacent wiring grooves 3 in both the vertical and horizontal directions. Therefore, the amount of the wiring groove 3 tends to be insufficient in the entire floor device formed by arranging the plurality of floor panels 1 side by side. In particular, there is a problem that the wiring groove 3 is insufficient because the cables are densely packed around the distribution board. Further, in the past, in consideration of workability, the floor panel 1 has a plane size of, for example, 500 mm × 500 mm, and when a plurality of floor panels 1 are vertically and horizontally arranged, a grid-like wiring is provided. Since the pitch between the wiring grooves 3 in the vertical and horizontal directions of the groove group 3 is the same and is as long as 500 mm, for example, there are restrictions on the wiring design. Moreover, since the plane size is, for example, 500 mm × 500 mm, a molding machine of 800 to 1000 tons is required for molding with synthetic resin.

Therefore, the present invention solves the above problems and provides a wiring floor panel in which a large amount of wiring grooves can be obtained when a plurality of floor panels are arranged, wiring design is easy, and manufacturing is easy. It is in.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below. FIG. 1 shows an example of an embodiment of a floor panel 1 of the present invention, which is integrally formed of synthetic resin. The floor panel 1 has a rectangular shape in a plan view, and the length-width ratio is (2/3): 1. Specifically, in FIG. 1, the length is 333 mm and the width is 500 mm. There is. The floor panel 1 is vertically divided into two rows and horizontally into three rows, and divided into six block bodies 2. Here, the block body 2 has a square shape in a plan view, and specifically, the length L of one side of the block body 2 is (500/3) mm. Adjacent block bodies 2 are rotatably connected integrally by a thin hinge portion 30 near the upper end portion.

By the way, when integrally molding the floor panel 1 with a synthetic resin, the length is 333 mm as in the embodiment,
When forming a product having a width of 500 mm, it can be molded by a molding machine of about 450 tons. The floor panel 1 having a rectangular shape in plan view is provided with wiring grooves 3 which are orthogonal to each other in plan view. The orthogonal wiring grooves 3 are formed in the two vertically adjacent block bodies 2 and the three horizontally adjacent block bodies 2. That is, as described above, the wiring grooves 3 are formed in the two vertically adjacent block bodies 2 and the three horizontally adjacent block bodies 2 to form the orthogonal wiring grooves 3. Of the block bodies 2, four block bodies 2 are block bodies with wiring grooves, and the remaining two block bodies 2 are block bodies with a top plate 2c.

Here, in order to form the wiring grooves 3 which are orthogonal to each other under the above conditions in the six block bodies 2 which are vertically divided into two rows and three rows, as in an example of the embodiment shown in FIG. In the case where the wiring grooves 3 are formed in a substantially T shape in a plan view so as to be orthogonal to each other,
There is a case where the wiring grooves 3 are formed to be substantially L-shaped in a plan view so as to be orthogonal to each other as in the other embodiment shown in FIG. As the wiring grooved block body, there is a wiring grooved block body 2a having a linear wiring groove 3a which is open at both ends in the upper and longitudinal directions.
And the wiring groove 3 for the corner that is opened upward, front-rear, and left-right
and the wiring grooved block body 2b having 3b, and the wiring grooved block body 2a among the four wiring grooved block bodies is 3
One block body 2b with wiring grooves is provided.

Wall-shaped leg portions 4a are provided upright on both sides of the groove bottom of the wiring groove 3a of the wiring grooved block body 2a, and pillar-shaped at the four corners of the groove bottom of the wiring grooved block body 2b. The leg portion 4b is formed to stand upright. A top plate 5a is formed on the upper surface of the leg 4a, and a top 5b is formed on the upper surface of the leg 4b. Step portions are formed on the side surfaces on the wiring groove 3 side above the leg portions 4a and 4b, and lid receiving portions 6 are formed in upper and lower two steps, and between the lid receiving portions 6 in the upper and lower two steps. A recess 7 is formed.

A lid 8 is detachably attached to the upper opening of the wiring groove 3. The lid 8 is provided with a collar portion 9 for mounting on the upper lid receiving portion 6a and a rib 10 for mounting on the lower lid receiving portion 6b, and further, a lower end of the rib 10 is lower than the rib 10. An engaging protrusion 11 protruding downward is provided. And
As shown in FIG. 4, the collar portion 9 is placed on the upper lid receiving portion 6 a, the rib 10 is placed on the lower lid receiving portion 6 b, and the engaging projection 11 is engaged with the recess 7. The lid 8 is attached to the upper opening of the wiring groove 3 so that the lid 8 is flush with the top plate portion 5a and the top plate portion 5b. Here, even if a load is applied and the distance between both sides of the upper opening of the wiring groove 3 is about to be widened and the lid 8 is removed,
This can be prevented by engaging the engaging projection 11 with the recess 7.

The block 2c with a top plate is constructed by suspending legs 4c on the lower surface of the top plate 5c. The top plate portion 5c is flush with the top plate portions 5a and 5b. Wiring groove 3
Side openings 12 are formed in the side surfaces of the leg portions 4a and leg portions 4b on both sides of the wiring groove 3 side, and a hole portion 13 is formed in the top plate portion 5a (in the embodiment, in the embodiment). Although the hole 13 is formed only on the top plate 5a, the hole 13 may be formed on the top 5b). In this way, the hole 13 and the side opening 12
When the lid 8 is formed of a non-transparent material by providing
Even when the wiring groove 3 is closed with the lid 8, it is possible to confirm whether or not wiring is provided in the wiring groove 3 through the hole 13 and the side opening 12. Of course, when the lid 8 is formed of a transparent material, the inside of the wiring groove 3 can be directly checked through the transparent lid 8.

Thus, the floor panel 1 having a rectangular shape in plan view having the above-described structure is arranged in a plurality of rows and columns on a floor base material like a concrete slab as shown in FIG. To form. The wiring floor A thus formed is one in which the wiring grooves 3 are continuous to form a grid-shaped wiring groove group 3. In addition, this grid-shaped wiring groove group 3 has two blocks 2c in the horizontal direction in which the block body 2c with a top plate having no wiring groove 3 between adjacent wiring grooves 3 is provided.
However, in the vertical direction, one block body 2c with a top plate having no wiring groove 3 is interposed between the adjacent wiring grooves 3. That is, the pitch of the wiring grooves 3 in the horizontal direction is the same as the length (500 mm) of the long side of the floor panel 1 having a rectangular shape in plan view, but the pitch of the wiring grooves 3 in the vertical direction is a floor having a rectangular shape in plan view. The pitch is the same as the length of the short side of the panel 1 (333 mm), and therefore the number of wiring grooves 3 can be increased in the vertical direction.

As described above, a plurality of floor panels 1 are arranged vertically and horizontally to form a wiring floor A, and wiring groove groups 3 each having wiring grooves 3 arranged in a grid pattern are formed vertically and horizontally.
Is used for wiring. Wiring floor A
A floor finishing material (not shown) such as tile carpet is laid on the upper surface of the. Therefore, in the present invention, when a plurality of floor panels 1 are arranged vertically and horizontally to form the wiring floor A, the number of wiring grooves 3 can be increased in the vertical direction as described above, so that the height of the floor panel 1 can be reduced. However, even if the finishing height of the wiring floor A is reduced, the wiring groove 3 will not run short. Further, although the cables are densely packed in the main line portion (around the distribution board), in the present invention, the wiring line 3 is selected in the wiring groove 3 having a smaller pitch, while the wiring groove 3 is formed in the branch portion. The one with the larger pitch is selected.

When the floor panel 1 is placed on a floor base material such as a concrete slab, even if the floor base material such as the concrete slab is uneven, the floor panel 1 is divided into six blocks. Since the adjacent block bodies 2 are divided into two and are connected to each other by the thin hinge portion 30, the unevenness is absorbed by bending the thin hinge portion 30.

Here, since adjacent block bodies 2 are connected to each other by the thin-walled hinge portion 3 to absorb the unevenness of the floor base material such as concrete slab, the bottom portion of the wiring groove 3 is bent and the concrete is bent. There is no need to absorb the inferiority of the floor base material such as a slab. Therefore, even though the wiring grooved block bodies 2a and 2b are provided with the wiring groove 3, the wiring grooved block body is formed by thickly forming the groove bottom portion 15 constituting the bottom of the groove so that the wiring grooved block body 2a, 2b is not easily deformed. Make sure that 2a and 2b are not deformed. That is, the thickness of the groove bottom portion 15 is equal to the leg portions 4a, 4
The thickness is made thicker than the thickness of the portions forming b and 4c.

It should be noted that the floor panel 1 has protrusions 1 on its side edges.
6 is formed and the floor panels 1 are arranged side by side, as shown in FIG. 5, the end portion of the top plate portion 5c of the adjacent floor panel 1 is placed and the projecting tip of the protrusion 16 is placed on the adjacent floor panel 1. By closely facing the side surface of the leg portion 4c, it is possible to secure a constant interval with the adjacent floor panel 1.

[0018]

As described above, according to the present invention, wiring grooves that are orthogonal to each other in plan view are formed in a floor panel having a rectangular shape in plan view, and the floor panel is vertically and horizontally arranged in 2 rows and 3 columns. The floor panel is divided into six block bodies and the orthogonal wiring grooves are formed in two vertically adjacent block bodies and three horizontally adjacent block bodies. A large amount of wiring grooves can be obtained when a wiring floor is formed by arranging a plurality of wirings vertically and horizontally, and as a result, a sufficient wiring groove amount can be secured even if the height of the floor panel in the vertical direction is reduced. Since the pitch between the wiring grooves in the direction is short, the wiring can be easily designed. Further, since the vertical direction can be shortened, the molding machine can be small in size and excellent in manufacturing.
