Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a conductive connection in an antistatic tile car vent. The present invention relates to a method of constructing an antistatic tile carpet, which is constructed while connecting a plurality of tile carpet units i4.

Conventionally, a classical material tile called PRIN vinyl tile has been used as flooring material for offices and residences. This vinyl tile is hard.

In addition to problems such as being cold and uncomfortable to step on, and being easily tiring, it also lacked aesthetic appeal. For this.

Long carpets made of fibrous materials have come to be used instead of vinyl mail. However, this long carpet cannot be transported, brought in,
Construction is troublesome, and if there is local staining, it is not possible to replace the local area, and local repair can significantly impair the beauty of the area.

In recent years, tile carpets of various shapes, such as square, rectangular, and diamond shapes, have been increasingly used as bedding materials to solve the above-mentioned problems. This sturdy carpet tile is suitable for transportation.

Electrical installation and construction are easy, and local replacement is possible.

Moreover, it has the advantage that it is possible to form a desired pattern by combining all the tile carpets of each deer color.

However, tile car vents like this one too.

The disadvantage is that it causes static air flow like normal carpet.For example, in the case of a tile carpet, which is made of fiber material and consists of an upper surface layer and a backing layer formed on the back side, 1M fiber is used. When the fiber material forming the surface layer is made of a hydrophobic polymer, the upper surface layer is easily charged with static electricity due to friction or the like. Emperor 1 like this! In order to prevent this, it is recommended to mix conductive fibers such as carbon fibers or metal fibers in the upper surface layer. It was. Conductive material on the back side of the upper surface layer of the fiber.

For example, a carbon blank or a metal layer is coated with a conductive paint containing fibers to form an upper surface layer! It is also known to completely prevent In general, the backing material for rugs is 1 composite, 1
Alternatively, it is mainly made of natural rubber and is essentially insulating, which tends to accelerate the charging of the upper surface layer. It is also said that the entire rug can be made into an antistatic material having a conductive metal by completely mixing carbon black or metal powder or fiber N. When arranging the vent units on the floor, they are not necessarily connected to the joints of adjacent tile carpet units in a conductive manner, and the conductivity of each tile carpet unit often results in air gap noise between the layers. Forming a void in each tile carpet unit.

They are insulated from each other, or the 4 charges become insufficient, resulting in an unsatisfactory antistatic effect as a whole. [1illlIK The provided backing layer is a layer of adhesive material such as bitumen or atactic polypropylene, which is susceptible to permanent deformation due to thermoplasticity at room temperature, and a back surface such as paper affixed to the back surface of the layer. When installing all such tile carpets, it is necessary to peel off the adhesive material layer on the back side and attach the adhesive material layer to the floor surface, or to apply the adhesive layer on the back side. Instead, it is attached to the floor using adhesive strips. Tile carpets like the above Sα have a long ffr'i in that the adhesive material layer is easily deformed at room temperature, so it can be deformed along the floor surface and fitted to the floor surface. . However, the fluidity of bitumen and atactic polypropylene increases with increasing temperature and pressure.

In seasons or places with high temperatures, or by a large number of people 1@
In conventional tile carpets, the backing layer flows and deforms in places where the carpet is exposed to water, causing problems such as a lack of practicality and a complete loss of aesthetics.

However, if the backing layer that is easily fluidized and deformed as described above is made into a 41a conductive layer, adjacent tile carpet units will lie on the conductive backing layer that has expanded due to the fluidic change, and will be electrically connected. It becomes more than that. However, such a four-tortoise connection effect can always be expected. , top B
Flow deformation of the conductive backing layer as in C does not occur.

Therefore, when installing tile car vent units on the floor, active measures must be taken to connect the conductive layers between them.

Furthermore, in recent buildings, the electrical arrangement is done on the floor and then covered with a mat, for example.

7 The rat cable method continues to be developed. At this time, if the rug, especially the back side that is in contact with the floor surface, is conductive to the L9 of the conventional antistatic rug, if there is a leakage from the electrical conductor placed on the open surface, the personnel of the rug soil There is a risk of electric shock. For this reason, an electric shock prevention rug has been developed that includes a conductive surface layer made of a fiber material and an electrically insulating backing formed on the back side of the conductive surface layer. In a small type of tile carpet, it is difficult to sufficiently electrically connect all conductive units of each unit.

The purpose of the present invention is to provide a plurality of tile carpet units with a guide wall. , when placed on the floor.

Those doyoi layers? An object of the present invention is to provide a method for constructing a conductive connection of antistatic tile carpets that can be conductively connected to each other.

An uninvented conductive connection construction method for antistatic tile carpet that combines the above objects is to install a plurality of tile carpet units having four walls on a floor surface, and to connect adjacent tile carpet units to each other. Unit guide'I! +! ? , the characteristic is to make a conductive connection with a four-conducting connecting member.

Each tile carpet unit used in the method of the present invention preferably has one or more conductive layers having a resistance of 10 8 Ω-α or less, and there are no particular limitations on the structure or shape thereof.

For example, one tile carpet unit used in the method of the present invention has the following fibrous top layer and a backing layer. The upper surface layer of this tile carpet unit is made of a fibrous material, which may be either a woven or knitted fabric or a non-woven fabric, and one of these is used as the entire base fabric, and on the upper surface of the fibrous material, Pile layer (cut pile,
(may be loop pile or a mixture of these)
.

Alternatively, a fiber entangled layer may be formed. The fiber material forming the upper surface layer may be natural fibers (wool, etc.), recycled fibers (rayon, cupra, etc.), semi-synthetic fibers (acetate, etc.), or synthetic fibers (nylon, polyester, polyacrylic, etc.). polypropylene fiber, etc.), or a mixture of two or more of these. It's 1.

The upper surface layer may have a base fabric and a pile layer as described above, and the fibrous material forming these may be spun, yarn, multifilament yarn, monofilament yarn, or split yarn.

It may be any tape yarn or the like.

In the above type of carpet tiles,
*The fine soil surface layer may be conductive, and in this case, the backing layer may be conductive, or.

It does not have to be conductive. In general, it is preferable that both the fiber surface layer and the backing layer are conductive! Yes.

In the method of the invention it is preferred to use a tile carpet unit having four layers in the backing layer.

These two fiber upper layers of the tile carpet unit may consist of only the conductive upper layer, but what about the R separation layer and the short conductive intermediate layer formed on the back side? It is preferable to have one. When the upper fiber layer consists of base fabric and pile elm,
It is necessary that either a part or both of the base surface and the pile chopsticks exhibit tetraelectricity. When the conductive upper surface layer has a fibrous layer and a conductive intermediate layer, the fibrous layer may have a 4'-containing structure.

It is L even if it is not conductive. If the fiber layer indicates 4, is it a fiber layer? Is at least a part of the forming fiber material conductive fibers? It is necessary to include The fibers having the structure 4 may be any of fibers such as fine fibers, metal fibers, or fibers containing a conductive material and/or a hygroscopic material or having an 8L layer.

The conductive intermediate layer may be a synthetic resin layer mixed with a conductive substance (powder or fiber), or may be a layer in which 4ik is embedded.

It is preferable that the conductive layer of the tile carpet unit used in the inventive method has a resistivity of 1010 Ω or less as a whole (more preferably, it has a resistivity of 10 Ω or less). On the surface layer, banding due to friction can be completely prevented.

The backing 1IIi of the tile carpet unit may have an electrical P conductive lower surface - 0 electrical P! 10' in the side table
. It is preferable to have a resistivity VC of Ω or more.

More preferably, this resistivity is greater than or equal to 10'2 Ω. This table/I is made of electric P edge synthetic resin, rubber, or the like. In order to make the contact between the rug and the floor completely soft, and to completely prevent irregular changes in the amount of current due to pressure, the lower surface layer should be made of porous elastic material 2 with a large number of pores, for example. It is preferably made of a foamed polyurethane layer or a foamed polyvinyl chloride layer.

The porous layer absorbs moisture at 1 o'clock and the electric power of the lower surface layer is P! In order to solve this problem,
The surface of the porous layer may be covered with an insulating sheet, such as a polyvinyl chloride insulating sheet, having a thickness of about 0.1 to 1.01111 mm. When used as a thin sheet metal layer, the fit between the car vent and the floor surface will not be particularly deteriorated.

Of course, a layer of porous elastic material on the lower surface may not be used.

Is your carpet tile damaged during use due to falling metal objects, etc.? If a hole is formed in the edge lining, electrical wiring on the top surface may pass through the hole and directly or indirectly into the conductive layer, causing an electric shock to a person. To prevent such accidents, ζ.

A protective layer made of an FRP board or the like may be formed.

When these protective I-eye pieces have electrical P2 image properties, the protective layer may also serve as an insulating lower surface layer. Also,
If the protective layer consists of gold plate.

This protective layer may also serve as a conductive intermediate layer in one surface layer. Further, it is preferable that the protective layer is not adjacent to the upper surface layer and is arranged so as not to be in direct contact with the floor surface.

The protective layer may be a flat plate, a sag, a net, a sieve, or a perforated plate (chestnut plate).

It may be of a shape that can be rolled up, such as a thin plate (membrane-like material), but it is important that each gap space of the body piece is as small as possible.

There is no particular limitation on the shape and dimensions of the tile carpet unit used in the present invention, but when it is selectively used in a part with electrical wiring on the floor, for example, 911 50c1nX50
The fact that it is a square of c+++ is 1 more advantageous for the case.
