Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a floor for laying on an exposed floor of a concrete building to form a floor base, or in a room in which a computer room or office automation equipment is installed. The present invention relates to a unit type floor panel for laying wiring grooves for power lines, telephone lines, information signal lines, etc. for each device.

[0002]

2. Description of the Related Art A unit floor panel for a floor base, in which a large number of small blocks made of concrete are aligned on one side of a flexible board in a vertical and horizontal plane with a small gap between them to be integrally joined ( Japanese Utility Model Publication No. 57-19392) is known.

Further, it is possible to connect a large number of small blocks with a flexible sheet instead of the above flexible board and to remove, for example, one or two rows of the small blocks aligned in one vertical and horizontal plane. One-way groove with a flexible sheet as the bottom,
A unit floor panel for floor wiring in which one or two rows are removed vertically and horizontally to provide cross grooves having a flexible sheet as a bottom or double girder grooves, and these grooves are used as wiring grooves (for example, JP-A-62-62). -284854) is also known.

[0004]

All of the above-mentioned known unit floor panels are simple in construction because they need only be laid on a concrete exposed floor surface. And if there is unevenness (unevenness) on the floor surface, the unit floor panel is uneven due to the flexibility of the boards and sheets that connect the small blocks to each other and the small blocks being separated and independent. Familiar, it is installed in a close contact.

However, these known unit floor panels have flexibility over the entire surface of the panel, so
If the unit area is large, it will be difficult to handle during transportation and construction.
Therefore, it is not suitable for floor panels with a large area per unit. Also, when the weight of the installed computer, filing cabinet, and other large fixtures concentrates on a specific part of the unit floor panel, the small blocks that support the weight are small and the strength of each small block is large, as explained in the next section. Therefore, the small block that receives the weight may be damaged.

In the above conventional unit floor panel, it is preferable to reduce the planar area of each small block in order to fit the entire panel surface to the floor, that is, in order to provide average flexibility. However, when the small block is composed of a shell, it is difficult to mold the small block to be taller than the cubic shape due to the molding technology. Therefore, the minimum height required to obtain the wiring groove is 40 mm. The present situation is that a small block is formed into a cubic shape having a length of 40 mm, a width of 40 mm, and a height of 40 mm.

However, depending on the construction site, a unit floor panel having high strength (thickness) or a unit floor panel having a large capacity wiring groove may be required. For example, if a unit floor panel having a height of a small block of 80 mm is set due to the required depth of the wiring groove, the vertical and horizontal dimensions of the plane of each small block cannot be set to 80 mm or less due to the above-mentioned molding technique. Therefore, the plane area of each small block becomes large, and the division by the small blocks on the unit floor panel is reduced, resulting in poor compatibility with the floor. In addition, the above-mentioned conventional unit floor panel, which is formed by vertically and horizontally arranging the small blocks, has an escape space between the small blocks when the panels are bent. There is a case where the walking sound escapes and reverberates in the void, impairing the walking sensation.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been proposed for the purpose of solving the above-mentioned problems in a unit floor panel, in which the panel main body is hollow with at least a smooth upper surface and side surfaces and the lower surface is open. It is characterized in that it is composed of a hard shell, and that the lightweight filler is filled in the shell to the height of the shell. The lightweight filler in the shell may slightly project at least on the outer peripheral portion of the lower surface of the shell. A fragile portion may be formed on the shell body from the upper surface to the side surface.

[0009]

When the unit floor panel of the present invention is laid on the floor, some unevenness of the floor surface is absorbed by the deformation of the lightweight filler exposed on the bottom surface of the panel, and the rattling of the panel is prevented. Absent. Since there is no gap in the unit floor panel itself, no abnormal noise is produced when walking. And since the unit floor panel is a solid product filled with a lightweight filler, it is easy to handle and robust, and can stand heavy objects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a unit floor panel according to the present invention will be described with reference to the drawings. In FIG. 1, a large number of unit floor panels (abbreviated as panels hereinafter) P are exposed on concrete, and a wiring groove forming member (for example, channel shape member) S also serving as a spacer is placed on a floor F with its opening side facing down. It is shown that the wiring grooves C are provided in a grid pattern by sequentially laying them while interposing them therebetween. Panels P are sequentially laid between adjacent panels at a constant interval corresponding to a wiring groove, and a finishing plate material having strength is laid on the upper surface of all panels including the wiring groove portion to be flat as a whole. It is also possible to do so.

The hard shell 1, which is the main body of the panel P, is hollow and has an open lower surface, that is, in the shape of a box lying down, and the light weight filler 2 is inside the shell at the height of the shell 1. It's full. As the hard material forming the hard shell body 1, a steel plate, a stainless steel plate, a hard plastic, or the like can be used. In the case of a metal plate, press working, especially draw forming means is suitable, but welding or other means may be used. For hard plastic, integral molding is suitable. As the lightweight filler 2, lightweight (foamed) concrete, foamed plastic (made of styrene resin, etc.), foamed aluminum, honeycomb material (made of aluminum, plastic, etc.) is suitable.

An example of means for filling the light weight filler 2 into the hard shell 1 is as follows: (1) Fill the inner space of the hard shell 1 with the viscous filler 2 and cure and solidify it. A removable partitioning material is placed on the ceiling portion of the inner space of the shell body 1 and the filling material 2 is filled therein, so that the solidified filling material 2 is provided with slits to form a divided shape. Alternatively, by filling the filler 2 with a gap left between the partition member and the ceiling, the fillers can be formed to be connected to each other in the upper back portion of the slit.

(2) The light-weight filler 2 is formed in advance in an integral shape or a plurality of divided shapes having a size that fits in the hard shell 1 in advance, and the light-weight filler 2 fitted in the hard shell 1 is bonded with an adhesive. It is fixed to the hard shell 1 by, for example.

The hard shell 1 of the panel P shown in FIG. 1 has a rectangular box shape in plan view. The shape of the hard shell 1 in plan view is that of the circle or square of FIG. It is arbitrary such as a triangle. Further, the hard shell 1 of FIG. 1 has a simple box shape, that is, the upper surface and the side surface of the box shape are smooth surfaces, but as shown in FIG. 2, FIG. 3, and FIG. It is possible to form the flange portion 3 in the peripheral edge so as to have a rectangular shape in a plan view and to provide the step portion 4 at the ridge line portion where the upper surface and the side surface are in contact with each other.

As shown in FIG. 2, when the panels P are spread over the floor F, the flange portions 3 around the hard shell 1 are abutted with the flange portions 3 of the adjacent panels P so that the width of the wiring groove C can be reduced. Acts as a spacer that determines Then, the step portion 4 facing the upper surface opening of the formed wiring groove C.
4 is a cover plate S1 having a thickness equal to the height of the step portion 4.
Is fitted in a drop-in manner to cover the upper surface opening of the wiring groove C. A finishing material 5 such as a carpet tile is stretched on the panel P flattened by fitting the cover plate S1.

When the panel P of the present invention is laid as shown in FIGS. 1 and 2, some unevenness on the floor is absorbed by the deformation of the lightweight filler 2 following the unevenness. It When the unevenness is large and cannot be absorbed, the rattling of the panel P is eliminated by laying a thin foam sheet 6 on the floor surface prior to laying the panel P.

The panel P shown in FIG. 5 is constructed so as to sufficiently absorb the unevenness of the floor without laying a foam sheet on the floor. That is, the lower surface of the light weight filler 2 filled in the inner space of the hard shell 1 slightly projects below the lower end edge of the hard shell 1 2a.
The bottom edge of the hard shell 1 does not contact the floor surface. The height of the protrusion 2a on the lower surface of the lightweight filler 2 is appropriately set to 2 to 4 mm in the case of a panel P having a height of 80 mm, for example. And the lower surface protrusion 2 of the lightweight filler 2
In addition to the flat surface of FIG. 5, a is a continuous contour shape (which may be discontinuous) illustrated in FIGS. 6A and 6B, a dotted shape illustrated in FIGS. 7A and 7B, and FIG. (a) and (b) include fine irregularities on the entire surface. In the case of FIGS. 7A and 7B, the protrusions 2a located at the four corners are made slightly higher than the protrusions 2b at other positions, and in FIGS. 5 and 8A and 8B, the central portion is slightly recessed. By doing so, as in the case of FIGS. 6 (a) and 6 (b), sitting on the floor surface is good and it is also effective in absorbing unevenness.

The panel P shown in FIGS. 9 and 10 has a further improved absorption following effect on the unevenness of the floor.
From the upper surface to the side surface of the plan view in a diagonal direction (see FIG. 9,
Square shell), or the crossed diagonal direction in plan view (Fig. 10,
The fragile portion 7 is formed in the circular shell). By forming a small round hole, a small square hole, a long hole, or a slit 8 in a line, a weak portion 7 is formed between the adjacent holes. In the case where the hard shell 1 has the flange portion 3 at the lower end periphery, the slit 8 is also provided in the flange portion 3.
Is provided to allow expansion of the side surface of the hard shell body 1 including the collar portion 3, and the hard shell body 1 bends and expands at the position of the fragile portion 7 according to the unevenness of the floor, and lightweight filling The tracking of unevenness is improved in combination with the absorption of unevenness by the material 2.

The fragile portion 7 is formed on the hard shell 1 shown in FIGS.
When the fully divided type or the partially continuous divided type described in the section of the filling material of the example of FIG. 1 is applied as the lightweight filling material 2 of the panel P provided with, as shown in FIG. Diagonal slits 9 of the split filler 2 and the hard shell 1
The fragile portions 7 are aligned in the same direction and fitted and fixed to the hard shell 1. Further, as shown in FIG. 12, the completely divided filler 2
Also, similarly, the dividing line direction 10 is made to coincide with the direction of the fragile portion 7 of the hard shell body 1 and fitted and fixed to the hard shell body 1.

[0020]

Since the unit floor panel of the present invention has the above-mentioned structure, it is possible to obtain a floor panel having a sufficient thickness as compared with the conventional unit floor panel composed of a group of small blocks, and the strength is improved. Moreover, even if heavy furniture is installed, it is not damaged and is safe, and at the same time, the capacity of the wiring groove is increased when the wiring groove is formed by laying the floor panel. Since there is no gap like the conventional unit floor panel consisting of a set of small blocks, no abnormal sound such as reverberation is felt when walking.

Since the unit floor panel of the present invention is a solid product of the whole integrated type, it does not bend even if the area of one sheet is large, and since it is lightweight for its size, the construction work is easy. is there. For unevenness of the floor surface, deformation of the lightweight filler exposed on the bottom of the panel and deformation of the hard shell in the case of forming a fragile part in the hard shell add to the unevenness well and are stable However, there is no rattling of the unit floor panel, which is effective in improving the walking sensation.
