Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION FIELD The present invention relates to improvement of a floor structure of a building.

2. Description of the Related Art Recently, in offices and other buildings,
In the room where the equipment is installed, a floor structure is known in which a plurality of floor panels made of a plate-like body with legs are arranged on a concrete slab via a rubber cushion shoe, and a tile carpet is laid thereon. ing. Such floor structures are expected to rapidly spread because wiring work for electric wires and telephone lines can be easily and freely performed, and inspections and changes after the work are easy.

Problems to be Solved by the Invention However, according to the above floor structure, each floor panel must be arranged so as not to rattle, and for that purpose, it is necessary to strictly finish the upper surface of the slab so as not to have irregularities. . In addition, due to static electricity generated when a chair or the like slides on the tile carpet, dust is adsorbed and it becomes difficult to remove the dust. In order to prevent this situation, the tile carpet must be subjected to antistatic processing. There was also a problem that it took time to maintain the tile carpet.

It is an object of the present invention to solve these problems and to provide a floor structure capable of coping with a certain degree of unevenness of a slab and controlling static electricity generated on a tile carpet.

Means for Solving the Problems The present invention provides a conductive floor panel in which a top plate having a flat top surface and a plurality of legs are integrally formed and arranged on a slab to form a floor; It is a laminated body in which a conductive carpet to be laid and a sheet-like fiber layer in which carbon fibers are stacked on both sides of a wire mesh are laid on a slab, and a floor panel is placed and electrically connected. And a mat to be connected.

In the floor structure, the wire net has a mesh finer than the bottom diameter of the floor panel legs, and is connected to a ground wire.

The static electricity generated on the carpet is released from the carpet, through the floor panel, the mat, and the ground wire connected to the mat, so that the static electricity does not remain on the carpet.

In addition, the mat serves as a cushioning material for the floor panels, and reduces the height difference of the slab surface so that the top surface of each panel is in the same plane.

The conductivity of the mat increases as the pressure applied to the mat increases.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a partially exploded perspective view.

As shown in these figures, the floor structure of the present invention includes a floor panel 2 disposed on a slab 1 of a building, a tile carpet 3 spread over the floor panel 2, and a slab 1 below the floor panel 2. A mat 4 to be laid on top and to which a ground wire is connected, wherein the floor panel 2, the tile carpet 3 and the mat 4 are each made of a conductive material.

The floor panel 2 is made of, for example, a well-conductive board formed by mixing raw materials obtained by kneading polypropylene, calcium carbonate, and carbon at a ratio of 70: 15: 15% by weight and measuring 250 mm × 250 mm × 50 mm in height × width × height. Having a flat top surface,
A 20 mm-thick top plate 6 having a number of holes 5 for reducing the weight is arranged in three rows vertically and horizontally including four corners.
and a leg 7 of mmφ.

According to the embodiment, the tile carpet 3 is 500 mm × 500 m
And a thickness of 7 mm. The pile is 3mm long
The conductive fiber is used, and the backing material is also provided with conductivity by special processing. When the tile carpet 3 is laid on the floor panel 2, it is arranged such that the seam does not overlap with the seam of the floor panel.

The mat 4 comprises a fiber layer 10 of activated carbon fiber and a wire mesh.
11 and formed from.

Carbon fiber can be obtained by converting organic fiber from 800 ° C to 1800 in a nitrogen atmosphere.
It is fired at a high temperature of ° C. to form fibers leaving almost only carbonaceous materials. The fibers are activated, have strong adsorptivity to gases or solutes, and have enhanced conductivity. Therefore, carbon fiber has high heat resistance, high strength, high elastic modulus,
It has high odor absorbing and moisturizing properties and high conductivity.

In forming the mat 4 shown in the longitudinal sectional view of FIG. 3 by using the carbon fiber, the mat 4 is formed by stacking carbon fibers in a card web form and stacking them into a sheet-like fiber layer 10.
Are arranged on both sides with a wire mesh 11 therebetween, and the overall thickness is about 5 mm in a non-pressurized state.

The wire mesh 11 is braided using a 0.5 mm metal wire, and the size of the mesh is smaller than the bottom diameter of the legs 7 of the floor panel 2 and is preferably about 5 mm or less. The mat 4 is wound into a roll for convenient transportation and use.

It is desirable to use copper wire as the material of the wire mesh 11,
Other inexpensive metals, such as copper wire and iron wire, are used for cost reduction.

At the time of construction, as shown in FIG. 1, a mat 4 is spread over the entire surface of a slab 1 which is a substantially flat surface of a building, and a ground wire 15 is connected to one end of the wire mesh 11. When arranging the floor panel 2 on the mat 4, the floor panel 2 is arranged side by side along the finishing mortar 21 inside the outer wall 20, but actually, the cushion rubber is mounted inside the finishing mortar 21. Arranged in contact with 22. At this time, the positioning is performed using the positioning member 9 so that the side surfaces of the floor panels 2 form the same plane in the vertical and horizontal directions.

The positioning member 9 is made of metal or plastic, for example, vinyl chloride resin. As shown in the perspective view of FIG.
The two circular tubular portions 16 are connected in the vertical and horizontal directions by connecting ribs 17, and the pitch between the tubular portions 16 is such that when the floor panel 2 is arranged in abutting relationship, the legs 7, 7 opposed to each other. Equal to the pitch. The inner diameter of each cylindrical portion 16 is set slightly larger than the outer diameter of the leg 7. This positioning member 9 is such that the four legs 7 of the four adjacent floor panels 2 which are close to each other are inserted into the respective cylindrical portions 16 of the positioning member 9 so that the floor panels 2 are not separated from each other. Position.

A baseboard 23 is attached to the bottom of the inner wall where the tile carpet 3 contacts the finishing mortar 21.

According to the floor structure of the present invention, it has a cushioning effect. In particular, the wire mesh 11 serves to reduce the unevenness of the slab 1 due to the deformation of the thickness, and even when there is a slight difference in the surface of the slab 1, the floor panel 2 does not rattle, and the top surface of each floor panel is It is adjusted to be in the same plane. This floor structure is used, for example, in a room where AO equipment is installed, and even when a heavy object is placed on the floor, the wire mesh 11 can withstand the load well, and the larger the load, the more the tile carpet 3 and the floor panel 2
Further, pressure is applied to the mat 4 and the contact state is improved, whereby the floor panel 2 and the mat 4 are electrically connected reliably and the conductivity is improved. Therefore, even if static electricity due to friction or the like is generated on the tile carpet 3, it is conducted from the tile carpet 3 to the floor panel 2, further reaches the mat 4, and escapes from the ground wire 15 via the wire mesh 11 of the mat 4, so that the tile There is no phenomenon that static electricity remains on the carpet 3 and dust accumulates, and other troubles caused by static electricity do not occur.

 The positioning member 9 can be omitted.

Instead of the tile carpet 3 of the above embodiment, a normal floor carpet is also used.

Effect of the Invention As described above, in the present invention, a conductive mat, a floor panel, and a carpet are provided in order from the bottom on the slab, and the floor panel is formed by integrally forming a top plate having a flat top surface and a plurality of legs. The mat is a laminated body in which carbon fibers are stacked in a sheet shape on both sides of a wire mesh, and the floor panel and the mat are electrically connected. For this reason, even if static electricity is generated on the carpet, the static electricity is easily dissipated and dust can be prevented from adhering to the carpet, and adverse effects due to the static electricity can be prevented.

Further, since the mesh of the wire mesh is smaller than the bottom diameter of the legs of the floor panel, the legs are reliably placed on the wire mesh, the cushioning action by the wire mesh is promoted, and the height difference of the upper surface of the slab is eliminated.

Furthermore, since the mat has a moisture absorbing property, a heat retaining property, a deodorizing property, and a soundproofing property, it has a great effect in improving the indoor environment.
