Description

Detailed Description of the Invention [Industrial Application Field] The present invention is used to interpose the tile carpet between the floor surface and the tile carpet, so that the tile carpet can be fixed or temporarily attached directly to the floor surface using an adhesive or the like. The present invention relates to a non-slip sheet that can prevent joint formation and jump-up at the joints between carpet tiles, and a method for laying carpet tiles using the sheet.

[Prior Art] Traditionally, the structure of tile carpets is that the upper layer is made of yarn made of 100% fibers such as polyester, nylon, acrylic, polypropylene, animal hair, or rayon, or the pile part is made of a blended yarn made of a mixture of these fiber materials. and a backing part that supports the pile part and is made of a hybrid material of vinyl chloride and glass fiber as a lower layer, or supports the pile part that is made of a backing of bitumen and a nonwoven fabric sheet. A variety of tile carpets are available with different pile lengths and thicknesses of the backing part, but usually the backing part has a wall thickness of 3 mm, the pile length is 5 mm, and the total thickness is 5 mm. It is approximately 8mm. In addition, there is a completely special type of double-sided pile tile carpet, but this has a different structure from the above-mentioned tile carpet, in that both the front and back sides of the tile carpet are made of pile that functions as a carpet. be. The dimensions of each carpet tile are usually 457 to 500 mm x 457 to 500 mm square.

In addition, among the carpet tiles mentioned above, except for special double-sided pile carpets and those with uneven areas around the tile carpet described later, the most popular method for installing them is to lay them on the floor surface. Or, on the back side of the backing part of the tile carpet, apply synthetic rubber latex type ti,
In this method, tiles are laid by applying an acrylic emulsion-based beer-up type adhesive or pressure-sensitive adhesive and fixing or temporarily attaching carpet tiles to each other on the floor surface. In addition, as a similar method, a method is known in which carpet tiles are laid on the floor surface in an adhesive state by interposing double-sided adhesive tape for carpets and cushion floors, or beer-up type double-sided adhesive tape. There is.

In these carpet tile construction methods, the reason why the carpet tiles are directly fixed or temporarily attached to the floor surface is as follows.

In other words, when carpet tiles are simply placed one after the other on a floor surface without gluing, etc., if a heavy roller or the like is run to apply a load to the carpet tiles, external pressure will be applied. This causes the tile carpet to bend, causing joint cracks and jumps at the joints (I! seams) of the tile carpet, making the area uneven and detracting from its aesthetic appearance, as well as causing damage to the tile carpet when it is laid. You end up in a state where you are out of your place and playing around. However, according to the above-mentioned carpet tile installation method, the carpet tiles are fixed or temporarily attached to the floor surface and do not bend even if a load is applied from the top surface of the carpet tiles. This is because it has the advantage of not causing inconveniences such as jumping or missing.

Furthermore, in order to achieve the above advantages without directly adhering the tile carpet to the floor surface, a recess or a convex part is formed around the tile carpet, and each adjacent tile carpet is fitted with the surrounding uneven part. For double-sided pile tile carpets, a sheet with the male part of a velvet fastener is glued to the floor, and the loop pile on the back side of the tile carpet is connected to the velvet fastener. A construction method is also known in which a tile carpet is laid by using it in place of the female part of the tile and engaging with the male part.

On the other hand, various types of non-slip sheets have been proposed that are interposed between the floor and piece carpets, laid-down carpets, and mats to prevent slipping. have.

■A sheet made of polyurethane resin partially placed on the surface of a net made of polyester synthetic fibers, and this resin is made into an elastic foam layer with a diameter of about 2 to 5 mm.

■Thickness 1 to 1 made of natural rubber or synthetic rubber molded into a mesh shape.
Sheet about 0mm.

゛■■ A flat sheet with a thickness of about 1 to 15 mm made of natural rubber, synthetic rubber, or foamed urethane, or a sheet obtained by deforming the flat sheet into a corrugated shape to improve cushioning properties.

The reason why each of the above-mentioned non-slip sheets has a certain degree of wall thickness and cushioning properties is that when a load is applied from above or diagonally, the stress due to the load is dispersed over the entire surface to improve the anti-slip effect. This is for the purpose of improving footing comfort. Therefore, in the case of conventional non-slip sheets that can only be laid down, a certain degree of cushioning properties are essential, and for this purpose a thickness of about 1 to 15 mm is inevitably required.

Therefore, among the above-mentioned carpet tile laying methods, the method of directly gluing or temporarily attaching the tile carpet onto the floor surface was abolished, and the non-slip sheet according to the above-mentioned conventional technology was interposed between the floor surface and the tile carpet. The disadvantages caused by this will be explained below with reference to FIG.

As shown in Figure 1, when a non-slip sheet (the sheet described above) is laid on the floor of a building and a tile carpet is laid on top of it, the non-slip sheet acts as a non-slip sheet for the tile carpet. On the other hand, because it has a lot of cushioning properties, for example, when heavy rollers (casters) are run on the top surface of a tile carpet, as shown in Figure 1 (A) to (C), Jumps and joint formations occur at the joints of carpet tiles that are being laid, and if excessive, the carpet tiles will completely come off the spot and become loose.

Therefore, there are serious problems in using the conventional non-slip sheets as anti-slip sheets for tile carpets, and they cannot be used as underlay materials for tile carpets. .

[Problem to be solved by the invention] Today, with the advent of intelligent buildings, high-tech buildings have become more advanced in information communication that transmits audio, video, etc. in response to the advanced information society and digitalization. For floor wiring in certain offices, in place of the various conventional floor duct wiring systems, undercarpet systems and raised floor systems using planar cables, which have flexible functionality and provide an excellent office environment, are becoming popular.

In the former method, an insulated planar cable with a thickness of about Inm is placed on the floor, and a tile carpet is laid on top of it. It has the advantage that the tile carpet can be easily restored. In addition, the latter method is a method in which the floor is a double floor (a floor panel including support legs is placed on the floor surface) and cables are installed in the gap between the upper and lower floors, and the existing wiring This has the advantage that the cable (general round cable) can be used as is, and the tile carpet can be laid on the top surface of the floor panel.

On the other hand, although there are various methods for cleaning carpet tiles laid on a floor surface, the cleaning methods that can be expected to have excellent cleaning effects are limited to the following.

■A cleaning method that uses detergent and water (hot water) with a combination of shaming volisher and rinse extractor.

■Cleaning method using non-foaming detergent and hot water using a rinse extractor and power wand.

■This is the so-called pick-up cleaning method, in which carpet tiles are removed one by one from above the floor and then cleaned using water and detergent in a separate cleaning machine.

However, in the above-mentioned undercarpet method or raised floor method using planar cables,
If the above-mentioned carpet tile installation method is adopted, in which the tile carpet is directly fixed or temporarily attached to the floor surface, which can best prevent joint formations and jumping up at the joints between the tile carpets, the following problems will be exposed. becomes.

That is, if the cleaning methods related to ■ and ■ above are applied, first,
In the undercarpet method for flat cables, cleaning workers use more water (hot water) and detergent than necessary, which causes the cleaner to penetrate through the joints of the carpet tiles while they are being installed and get behind the carpet tiles. It remains unsuctioned by a rinse extractor, etc., and it adheres to and stagnates on the flat cable installed on the back side of the tile carpet, or water leaks through the gap between the flat cable and the tile carpet.
Changes over time will induce corrosion of the cable insulation and part of the connector. In addition, in the raised floor system, as mentioned above, excess water and detergent enter through the joints of the carpet tiles, and furthermore, enter through the joints of the installed floor panels and accumulate on the floor surface. The moisture that remains on the floor surface without being sucked up by a rinse extractor etc. will induce corrosion of the insulation part of the cable installed between the floor surface and the floor panel and some of the connectors. .

In today's office environment where OA equipment is rapidly introduced, the above-mentioned disadvantages may cause unexpected accidents such as erasure of input data, resulting in great damage. Furthermore,■
When applying the cleaning method related to the pick-up cleaning method, the carpet tiles are directly fixed or temporarily attached to the floor surface in the undercarpet method, and on the floor panel in the raised floor method, respectively. It takes time to remove the carpet tiles, which may damage the back side of the carpet tiles or cause dirt to adhere to them.Also, since the carpet tiles are stacked and transported, the adhesive may transfer to the pile, which may cause damage to the carpet tiles. This caused an increase in cleaning costs. In addition, by directly fixing or temporarily attaching carpet tiles to the floor surface or floor panel with adhesive, etc., and peeling off the carpet tiles each time it is washed, dirt may adhere to the floor surface and scratches may occur. In particular, if there is an obligation to restore a leased building to its original condition at the time of delivery, if homogeneous style materials are used as flooring materials, all tiles must be replaced. However, there was an inconvenience that the cost burden associated with moving out would increase.

The present invention solves the above-mentioned drawbacks of the prior art, and eliminates joint formations and jumps at the joints between carpet tiles without directly fixing or temporarily attaching the carpet tiles to the floor surface using an adhesive or the like. This is one of the methods for cleaning tile carpets that can be prevented and is installed using the undercarpet method or raised floor method for flat cables, which is becoming popular today. The cleaning method between the floor surface and the tile carpet, which can be expected to have the best cleaning effect, is extremely easy and can be carried out without staining the ground surface of the tile carpet, such as the floor surface. The present invention provides a non-slip sheet to be used as an intermediary between the sheets and a method for laying carpet tiles using the sheet.

[Means for Solving the Problems] The present invention relates to a non-slip sheet and a method for laying a tile carpet using the sheet to achieve the above object. The sheet (1) is composed of a mesh fabric made of synthetic fibers made of polyester, acrylic, nylon, polypropylene, etc., and polyurethane resin etc. The anti-slip agent is applied without foaming, and the anti-slip agent is applied in the mesh hole (2) of the part with a thinner thickness than the surrounding member (4) constituting the mesh hole (2). (3
), forming a sheet (1) with a maximum wall thickness of inm or less, and the contraction width and recovery width of the sheet (1) when applying or releasing external pressure due to a load from the top surface are both 0.25 m.
It is characterized by being prepared to be less than m.

Further, the invention according to claim 2 relates to a method for laying a tile carpet using the non-slip sheet (1) according to claim 1, wherein the non-slip sheet (1) according to claim 1 is placed on a floor surface. Next, lay a tile carpet on the top surface of the non-slip sheet (1), and place the non-slip sheet (1) between them without directly fixing or temporarily attaching the tile carpet to the floor surface with an adhesive or the like. It is characterized by the fact that it is interposed.

[Function] By the above-mentioned means, first, in the non-slip sheet (1) according to claim 1, synthetic fibers made of a constituent material such as polyester are knitted into a mesh fabric, and the fibers constituting the mesh fabric are knitted into a mesh fabric. Since an anti-slip agent such as polyurethane resin is applied to the entire periphery of the material without foaming, there are many mesh holes (2) in the mesh fabric, making it possible to see through the back side. By coating the surface with an anti-slip agent, the frictional force with other members increases.

In addition, the non-slip sheet (1) has a maximum wall thickness of 1 mm or less, and the contraction width and recovery width when applying or releasing external pressure due to a load from the top surface of the sheet (1) are both 0.25 m.
m or less, and has almost no cushioning properties.

In the method for laying a tile carpet using the non-slip sheet (1) according to claim 2, the non-slip sheet (1) according to claim 1 is laid on the floor surface, and then, in step 1, the non-slip sheet (1) is Sheet (
1) A tile carpet is laid on the top surface,
The back side of the tile carpet comes into contact with and adheres closely to the upper surface of the non-slip sheet (1) laid on the floor surface, and the back surface of the non-slip sheet (1) comes into contact with and adheres to the floor surface. In this case, since the outer periphery of the non-slip sheet (1) is coated with an anti-slip agent, the tile carpet itself is prevented from slipping due to external force applied to the tile carpet.

In addition, when interposed between the floor surface and the tile carpet, the convex part of the fine unevenness on the back side of the lower layer backing material, which is a component of the tile carpet, becomes a mesh hole (2).
The tile carpet and the non-slip sheet (1) are in good contact with each other, and the contact area between them is increased, which prevents deformation due to the load applied to the tile carpet as described below. becomes easier to do.

As mentioned above, the non-slip sheet (1) has both a contraction width and a recovery width of 0.0 when external pressure is applied or released due to a load from the top surface. When a load is applied to the upper surface of a tile carpet, which is adjusted to 25 mm or less and has almost cushioning properties, the following effects occur. Second
As shown in Figure (A), when the carpet tiles are laid on the floor without being fixed or temporarily attached, a heavy roller is placed on the top of the carpet tiles to apply a load, and the Run left and right. In this case, the frictional force between the back surface of the backing part of the tile carpet and the floor surface is low, and it is not possible to prevent the bending that occurs from the left and right sides of the tile carpet due to the stress generated in the backing part due to the load. This causes jumps in the joints and joints at the joints between carpets. On the other hand, as shown in FIG. When a roller is placed on the tile carpet and moved from side to side under a load, the stress dispersed in the backing part of the tile carpet is applied to the non-slip sheet (1) that is in close contact with the back side of the backing part. The non-slip sheet (1
) is prevented from deforming together with the tile carpet, and as a result, since the back surface of the backing part is in close contact with the top surface of the non-slip sheet (1) with frictional force, the generation of deflection of the tile carpet itself is prevented. What you get screams. In this case, as mentioned above, the non-slip sheet (1) itself has almost no cushioning properties (even the backing part of the tile carpet has almost no cushioning property), and the backing part of the tile carpet hardly slumps under the load. Therefore, joints and jumps do not occur at the joints between adjacent carpet tiles.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 's3 shows the non-slip sheet (1) according to claim 1.
) is a plan view of

Polyester and acrylic are used as rope materials.

Synthetic fibers made of constituent materials such as nylon and polypropylene are suitable, and in this example, warp and weft yarns made of polyester synthetic fibers with a thickness of about 0.1 mm are knitted into a mesh fabric in the shape of a four-way basket weave. - A large number of vine-shaped mesh holes (2) with sides of about 3 mm are formed.

In this case, suitable synthetic fiber yarns include a single filament yarn as in this embodiment, a strand of several extremely fine filament yarns, a stable yarn, and the like.

Next, an anti-slip agent such as a polyurethane resin is applied to the entire periphery of the fibrous material constituting the mesh fabric without foaming. Then, a thin coating film (3) of an anti-slip agent is provided in some of the many mesh holes (2) in the mesh fabric.

As is clear from the partial enlarged cross-sectional view in Figure 344, the coating film (3) is smaller than the surrounding member (4) (a member coated with an anti-slip agent around synthetic fibers) surrounding the coating (3). It is formed with a thick wall. This is because if the surrounding member (4) that surrounds the coating film (3) rises higher than the surrounding member (4), the non-slip sheet (1) itself will be given cushioning properties, making it impossible to achieve the object of the present invention. .

By forming the coating @ (3), a non-slip sheet (1
) gives tension to itself, and at the same time, when interposed between the floor surface and the tile carpet, the convex part of the minute unevenness on the back side of the backing part of the tile carpet gets into the mesh hole (2). It comes into close contact with the coating film (3), and furthermore, the coating film (3) on the back side of the adhesion part comes into close contact with the floor surface, increasing the contact area with the non-slip sheet (1) and creating cushioning properties. This makes it possible to realize a good state of interposition of the non-slip sheet (1). However, in order to give the non-slip sheet (1) itself see-through properties for the reasons described later,
The formation of the coating film (3) is suppressed to about one-fourth of the total mesh holes (2). The thickness of the anti-slip agent coating is 0.
Approximately 15 mm is optimal, and the thickness of the coating is adjusted as appropriate depending on the thickness of the constituent fibers of the mesh fabric.

The non-slip sheet (1) constructed as described above has a maximum wall thickness (as shown in Fig. 3, the vertical and
The area where the horizontal filament threads intersect (point a on the drawing) is approximately 0.5 mm, and the contraction width and recovery width when external pressure is applied (50K g f / cr rr?) or released due to the load from the top surface of the sheet is approximately 0.5 mm. Both are adjusted to 0.25 mm or less.

5 to 7 are explanatory diagrams showing a method of laying carpet tiles using the non-slip sheet <1) according to claim 2.

As shown in FIG. 5(a), a reference line is marked out on the floor surface on which the tile carpet is to be laid. The reference line should be placed exactly perpendicular to the approximate center of the room, taking into account the size of the tiles near the walls and in the doorways.

Next, the non-slip sheet (1) according to claim 1 is laid on the floor surface on which the reference line has been marked. In this case, place the non-slip sheet (1) on the reference line, and
If it is necessary to check the reference line through the mesh hole (2), lay the non-slip sheet (1) over the entire floor so that it does not overlap.

Further, the mesh hole (2) is extremely small and the mesh hole (2) is extremely small.
2) If it is impossible or difficult to confirm the reference line through the
m. Lay the non-slip sheets (1) so that they do not overlap, with a total distance of about 5 mm and with the reference line visible.

In the construction process of (a) above, if the ends of the non-slip sheets (1) to be laid one after another are temporarily fixed with beer-up tape, etc., the sliding movement of the sheets (1) on the floor surface will be prevented. This makes the installation easier.

Next, carpet tiles are laid one after another starting from the part orthogonal to the marked reference line, and the temporary tape is peeled off and removed at the same time, completing the laying of the carpet tiles (see Figure 345 (b)).

Figure 6 (a) shows that in the raised floor system,
This shows a state diagram when the invention according to claim 2 is implemented, and in the same way as above, marking is performed by orthogonally crossing the reference line at the appropriate center of a large number of floor panels arranged on the floor surface, A non-slip sheet (1) is laid on the upper surface of the floor panel, and then carpet tiles are sequentially laid on the non-slip sheet (1) in alignment with the reference line. After the tile carpet has been laid, if it is necessary to repair or replace the wiring cables on the back side of the floor panel or relocate them, remove the tile carpet from the appropriate areas and remove the exposed non-slip sheet (1). Cut along the seams of the floor panel, remove the floor panel, and repair or replace wiring cables. For subsequent repairs, put the floor panel back in place and place the cut non-slip sheet (1) so that the edges overlap. The non-slip sheet (1) is laid on the top surface of the floor panel in such a way that the removed carpet tile is inserted into it for repair, and the cut non-slip sheet (1) can be reused.

FIG. 6(b) shows a state diagram when the invention according to claim 2 is implemented in an undercarpet system using a planar cable. Mark out the reference line, lay out the non-slip sheet (1), and then place a telephone on the top of the non-slip sheet (1).

Lay out each planar cable for data and power, then
This is completed by laying carpet tiles along the reference line.

When the present invention is applied to the above-mentioned undercarpet method, since a flat cable is arranged on the top surface of the non-slip sheet (-1), the flat cable can be replaced by simply removing the tile carpet. It becomes something you can do.

FIGS. 7(a) and 7(b) are implementation state diagrams showing another embodiment of the tile carpet laying method according to claim 2.

(a) When laying carpet tiles sequentially starting from the point orthogonal to the reference line marked out in the center of the floor surface, the points on the floor surface where the corners of adjacent carpet tiles join each other are determined in advance. A non-slip sheet (1) with dimensions of approximately 215 mm x 215 mm is placed at the center of each carpet tile, and the carpet tiles are laid in a predetermined order.

According to this embodiment, since the non-slip sheet (1) is not laid over the entire floor surface, the amount of the sheet (1) used can be reduced, and costs can be reduced.

In addition, (b) is a roll-shaped non-slip sheet (1) with a width of 215 mm, for example, placed parallel to the horizontal reference line and at a constant interval on the floor surface on which the reference line has been marked in the same way as above.
, and then sequentially lay carpet tiles along the reference line. As in the embodiment (a), it is possible to reduce the amount of non-slip sheet (1) used and the cost.

[Effect of the invention] Conventionally, when laying carpet tiles on a floor surface, the tile carpet itself is deformed (deflection occurs) due to the load applied to the top surface of the tile carpet, or the elasticity of the underlying cushion material, etc. In order to prevent joints and jumps from occurring at the joints between tile carpets, the tile carpets are glued or temporarily attached to the floor surface. The present invention solves the drawback that pick-up cleaning methods with high efficiencies cannot be practically adopted.

That is, according to the present invention, by simply interposing the non-slip sheet (1) according to claim 1 between the floor surface and the tile carpet, the same effect as in the prior art where the tile carpet is bonded to the floor surface can be achieved. This makes pick-up cleaning of carpet tiles easier.

In particular, in intelligent buildings that often use floor wiring systems, it is strictly prohibited to bring in water in places where the currently preferred floor wiring systems are the raised floor system or the undercarpet system using planar cables. Therefore, when cleaning tile carpets in that location, it is strictly prohibited to use a cleaning method that uses water, even if the dirt is removed well and there is almost no detergent residue. Therefore, when cleaning carpet tiles in such places, the dry ohm method, in which residual detergent accumulates, or the powder one-method, in which detergent powder remains in the carpet pile, which have many problems, are used. However, if you want a cleaning method that removes dirt well and leaves almost no detergent inside the carpet,
It is important that by carrying out the present invention, the removal and installation of carpet tiles can be performed extremely easily since the pick-up cleaning method must be relied upon.

In addition, there is no need to use adhesives or adhesives when installing carpet tiles, and when removing carpet tiles, there is no damage to the floor surface or dirt on the floor, so it is possible to install carpet tiles in a room in a building. This will reduce the cost of restoring the floor to its original condition when you move out, especially if you are renting a house. In addition, since no adhesive is used, there is no adhesive stains on the surface of the raised floor panel, and the floor panel can be moved to another location and reused as if it were new. Similarly, the tile carpet itself has the advantage of being able to be reused in other locations by closing it up like new if it is not soiled.

In addition, the non-slip sheet (1) according to claim 1 can be reused many times by washing with water and can withstand use over time, and the cost of installing carpet tiles can be reduced compared to conventional adhesives. This results in a reduction compared to the method used.
