Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a flooring panel suitable for configuring the flooring of an office room or the like equipped with OA (office automation) equipment.

(Conventional technology) Conventional flooring, especially office room flooring, is generally composed of only a concrete slab with a precision of 11ffi, and a synthetic resin finishing material such as vinyl chloride sheet or vinyl tile is pasted on the top surface of this concrete slab. At present, the majority of floor structures are made up of carpets and carpets laid on top of them.

Additionally, the present applicant has developed a floor base in which a number of support legs are interposed on the bottom surface of the panel to maintain a predetermined height from the floor base, and a so-called raised floor base panel with a space provided on the bottom surface of the panel. We proposed that the wiring be housed within the space.

[Problem to be solved]

In the conventional floor structure, wiring such as OAI equipment is installed by running on the floor surface, which not only makes the office room untidy but also has an unfavorable safety aspect. In addition, a floor structure consisting of only a synthetic resin finishing material applied to a concrete slab (floor base) has a hardness of 4 floors.
There are also increasing demands for improvements in the poor walking sensation and the feeling of cold feet.

In addition, as a result of actually constructing the floor sub-base panels as proposed by the applicant, although the wiring was able to fit better, it was time consuming to adjust the horizontal level of all the panels after laying a large number of panels. It has been found that there are many inconveniences, such as a large amount of friction, and furthermore, sinking, shifting, and springing occur at the points where the panels meet and at the edges of the panels, resulting in a loss of walking sensation.

[Means for solving problems]

This invention was invented in view of the above circumstances,
The wiring can be stored under the floor, and it is easy to move and change the wiring after construction, giving a large degree of freedom.It can absorb slight unevenness when laid on the top of the floor base, improving workability. The purpose of the present invention is to provide a floor base panel that can prevent panels from shifting, bouncing up, sinking, etc., as well as preventing floor noise and providing a soft walking sensation. In order to do this, a support leg for establishing a space between the panel and the floor base is located at least at the panel butting point or at the end of the panel, and a means for attaching and detaching the support leg to and from the panel is provided. It is installed on the bottom of the panel.

〔Example〕

Some preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an example of constructing a floor structure using the floor base panel of the present invention, in which a large number of unitized panels 1 are laid out on a floor base (concrete slab) 10. The panels 1 include a cutout panel IA with the end cut out, a panel 1B with an outlet and a connector, and a panel 1 with a connector and a telephone line outlet.
It is used in combination with G, corner panels 1D, etc. with corner portions cut out. By appropriately arranging these panels 1A to 1D, etc., it is possible to add functions such as power supply intake and output, and power supply circuit branching.

A support w3 for setting a space S is interposed between each of the panels 1 (including 1A to 1D; the same applies hereinafter) and the floor base 10. The support legs 3 are provided at least at the points where the panels 1 abut against each other or at the ends of the panels 1. Further, the support legs 3 are attached to the lower surface of the panel 1, and a detachable means 2 for this purpose is provided on the lower surface of the panel 1. As the attachment/detachment means 2, a sheet 20 made of a synthetic resin material or the like is adhered to a predetermined position on the lower surface of the panel 1, and a recess 21 into which the support leg 3 fits is formed in the sheet 20. Therefore, the sheet 20 in which the recess 21 is formed can be called a coupling sheet. This coupling sheet (sheet 20 and recess 21) is adhered to a predetermined position M (multiple places) on the lower surface of the panel 1, and the upper end of the support leg 3 is fitted into the recess 21. In this embodiment, the attachment/detachment means 2 is not provided only on the lower surface of the panel 1, but the attachment/detachment means 2 is also provided on the floor base 10. A coupling sheet was also used as the attachment/detachment means 2 on the side of the floor base 10, and a synthetic resin foam 4 having rubber elasticity was formed on the bottom surface of the coupling sheet (see FIG. 2). By using such a foam 4, squeaks, rattling sounds, etc. peculiar to floor panels can be prevented,
It provides a comfortable walking feeling with just the right amount of cushioning, and can even absorb even the slightest unevenness.

The panel 1 is 450x450 (u), 500x5
00 in>, 600x600 (mu), 900x9
Thickness 10-40 pre-formed to size such as 00(u)
It has a floorboard material 5 made of high grade particle board, synthetic resin, calcium silicate board, etc., and a finishing material 6 such as a carpet is attached on this floorboard material 5. A wall tape 7 is interposed at the point where the panel 1 and the wall meet.

As shown in FIGS. 3 and 4, the attachment/detachment means 2 includes a recess 2 in a sheet 20 that covers the entire lower surface of the panel 1.
1 may also be formed. The sheet 20 may be a thermoplastic resin material such as vinyl chloride resin or polyethylene resin having a thickness of approximately 0.5 to 3.0 mm and vacuum-formed to form the annular raised portion 21- and the recessed portion 21. The attachment/detachment means 2 shown in FIGS. 1 and 2 described above is the annular raised portion 2 shown in FIG.
It can be considered that only the recess 1', the recess 21, and the surrounding area are cut out.

Furthermore, the attachment/detachment means 2 only needs to be present at least on the panel 1 side, and the intended purpose can be achieved even if it is not present on the floor base 10 side. Further, although the attachment/detachment means 2 is provided separately from the floorboard material 5 constituting the panel 1, the floorboard material 5 may be made of, for example, FRP.
The recess 2'1 can also be formed integrally with the floorboard material 5 by molding the material and forming ribs or the like during molding.

In addition, as another attachment/detachment means 2, there is no problem even if it is a recess 21, a hole 22, or six places 23 as shown in FIGS. 5 to 7.

The support leg 3 has a structure as shown in FIGS. 8 and 9, and is used for the cross-shaped abutting portions of the panels 1. This connects the four members that become the legs (support legs) with a connecting part 30, and the support leg body itself connects the upper and lower divided bodies 31 and 33 with male screws 32 and female screws 34 so that the level can be adjusted. It is something that is. The male screw 32 is the divided body 3
By inserting the insert 1 when molding 1 with a synthetic resin material and inserting the female screw 34 when molding the divided body 33, it can be easily integrated with the respective divided bodies 31 and 33. . It goes without saying that seven screw fittings may be made in one piece after molding the synthetic resin. Also,
A hole 35 is formed in the center of the divided body 31, and this hole 3
Insert the screwdriver and screwdriver (not shown) from 5 and tighten the male screw 3.
2 (the divided body 31 is also rotated at the same time), the gap between the divided bodies 33 and 31 is adjusted, that is, the entire height of the support leg 3 itself is adjusted to Wa! can fJ'.

By forming a hole (not shown) for inserting a screwdriver in the corresponding part of the panel 1 corresponding to this hole 35, even after the panels 1 are laid down, the level 1 of the panel 1
Sections can be performed easily.

Support legs 3 as shown in FIGS. 10 to 12 (a) and (b) can also be used at the abutting portions and corners of the panels 1.

Note that the structure of the support 1l13 may be such that, contrary to the embodiment shown in FIG. 9, the divided body 31 provided with the male thread 32 may be installed on the floor base 10 side (see FIG. 13).

Furthermore, the support leg 3 may have a structure as shown in FIG. 14. This connects the male screw 32 to the divided body 3 made of synthetic resin material.
1 itself.

Furthermore, a spacer 40 as shown in FIG.
It is also possible to expand the space S to an arbitrary height by fitting it into the space S.

In the support leg 3 shown in FIG. 13, when the divided body 31 is directly grounded on the floor base 10, the divided body 31 is preferably made of a resin-based or rubber-based material having rubber elasticity. Alternatively, an elastic material such as a rubber cap may be fitted into the divided body 31.

In yet another embodiment, as shown in FIGS. 16 and 17, a predetermined portion of the floorboard material 5 is formed to protrude, and this protruding portion is used as a so-called divided body 33, and this divided body 33 is provided with a female thread 3. 4, and a split body 31 having a male screw 32 screwed into the female screw 34 is placed on the floor base 1110 side.
There is. In this embodiment, the attachment/detachment means 2 is the supporting leg 3.
The split body 33 and the female screw 34 are formed. The floorboard material 5 in this embodiment employs a sandwich structure of FRP material and synthetic resin foam material to reduce weight, or a hollow structure with ribs formed to improve strength.

Note that not only the support legs 3 but also a plurality of legs 36 may be provided on the lower surface of the panel 1. For example, as shown in Figure 18, the floor base! ! ! A ring-shaped raised portion 21- is formed on the sheet 20 (which may be made of synthetic resin foam 4) to be laid on the recess 21.
In addition to forming the ribs 36', the leg portions 36 may be formed.

The upper ends of the legs 36 fit into the attachment/detachment means 2 provided on the lower surface of the floorboard material 5.

When changing the wiring after the panels 1 have been laid down, if the support legs 3 are connected, as shown in Figure 19, if one panel 1 is peeled off, the next panel If panel 1 shifts sideways (arrow A in the figure),
There is no risk of falling down (arrow B in the figure).

When only one panel 1 has support legs on the lower surface, it is necessary to insert a support rod between the opposing panels 1 to prevent sideways slipping or overturning.

〔effect〕

As explained above, the present invention provides a method for interposing support legs for establishing a space between a panel and a floor base by positioning them at least at the panel butt points or at panel ends, and for attaching and detaching the support legs to the panels. A means for attaching and detaching the panels is provided on the bottom of the panel. By simply laying the panels on the floor base, the degree of freedom for wiring, etc. is increased, and by providing entrances and exits on the panels at the required positions, it can be installed over the shortest distance on the floor. It can be directly connected to 0AII equipment, and the wiring is scattered on the floor.
It can also relieve the feeling of coldness. Furthermore, since the panel is supported by support legs, it is possible to eliminate the poor feeling of walking caused by the hardness of the floor.

In addition, when attaching support legs to the attachment/detachment means, it is possible to absorb unevenness when the panels are laid out on the floor base by selecting the support leg or adjusting the height of the support leg itself, greatly improving workability. Improved. In particular, when the height of the support leg itself is adjustable, absorption of unevenness and workability are further improved.

Further, according to the present invention, since the support legs are present at least at the panel abutting portions and at the panel ends, sufficient improvement can be seen in the prevention of panel displacement, jumping up, sinking, and floor noise. In particular, further improvement was seen in the case where the support legs were connected to each other where the panels were adjacent to each other. As described in the explanation of FIG. 19, even when the panel is peeled off due to changes in wiring, the panel is prevented from shifting laterally or falling over.

The present invention is easy to implement not only when constructing a new floor structure but also when renovating an existing building.
