Description

Maintenance methods for tiles and tiled floors

The present invention relates to a method for maintaining a tile placed on a floor base or an existing floor to finish a floor, and a tiled floor finished with a plurality of tiles, such as a store, an office, a public facility, and an exhibition hall. It can be used for various floors. Background art

Tile floors, which can be finished by laying a large number of tiles made of plastic or the like on the floor base surface or the existing floor surface formed by concrete casting etc. It is used in restaurants, offices, and public buildings. Normally, these tiles are fixed on the floor base or the existing floor with an adhesive, etc., so even if they are being replaced, even if they are newly replaced, they are performed by skilled craftsmen and require a lot of construction time. In addition, in terms of easy workability, plastic tiles, which are laid down only on a floor base surface and can be removed, as described in Japanese Patent Application Laid-Open No. 8-42464, etc. May be used.

In such a conventional floor tile, a protective film is provided on the upper surface by applying or spraying a wax agent or the like in order to ensure a high glossiness.

The upper surface of the tiles laid where people enter and leave, the protective film gradually wears and scratches due to shoes and other footwear, and the object is dragged or dropped If you do, it will be damaged. In this way, if the protective film provided on the upper surface of the tile is worn out, the conventional method for repairing the protective film is to remove the remaining protective film and apply a new protective film. Work and spraying work to protect uniform thickness Since the film must be provided on the top of the tile, and this work is usually performed at the site where the work was performed, this work takes a lot of time and effort, and if it is performed in a store, it will hinder business hours. I was. Furthermore, in recent years, convenience stores that are open 24 hours a day have increased, and such work has become remarkable and may have disadvantages in sales activities.

Furthermore, in the past, tiles removed from the floor were to be disposed of and discarded as they are, but the treatment of them has significant environmental problems. Therefore, from the viewpoint of environmental protection, the development of recyclable tiles with a small amount of waste has been desired.

In view of the above situation, an object of the present invention is to provide a tile that can be easily repaired at a place other than a construction site when the upper surface is worn. In terms of disposal, the main part is to be reused or recyclable, and to provide tiles that are favorable from the viewpoint of environmental protection.

It is another object of the present invention to provide a method for maintaining a tiled floor finished using the tile. Disclosure of the invention

A tile according to the present invention is a tile which is detachably placed on a floor base or an existing floor, comprising: a tile main body; and a protective film fixed to the tile main body in a detachable manner, wherein the protective film is provided. Is characterized in that at least an upper surface, a side surface, and / or a lower surface of the tile body are continuously coated up to a part near the side surface. According to this tile, the tile body is directly damaged or damaged because at least a part of the upper surface, the side surface, and the lower surface of the tile body are covered with the protective film in a peelable manner. There is very little to do, and the protective film as the installed flooring will be worn or damaged.

If the protective film is damaged or the surface becomes dirty, the tile is detachably installed, so that the tile can be easily or partially replaced with a new tile of the present invention in a short time. After that, the used tiles are collected and transported to factories and the like. In factories, etc., used tiles can be used as new tiles because the protective film is peeled off and if the tile itself is not damaged, it is covered with a new protective film. If the tile body is damaged, the tile body will be repaired and can be reused. The irreparable damaged tile body and the peeled-off protective film are crushed and recycled for recycling, and used as new tile body material.

The term “protective film worn or damaged” as used herein generally means that the floor construction surface is worn or scratched by human walking, and that the wound is easily wiped with dust. Means that cleaning is no longer possible. In special cases, this includes cases where floors were damaged due to the movement of display shelves in stores and the like.

In addition, even if there is no problem on the floor surface itself, Even in such a case, the tile of the present invention can be easily redesigned, and the reuse and recycling of used flooring can be easily performed. In addition, since the protective film covers the entire upper surface of the tile body and a part of the entire side surface or the lower surface near the side surface, the following operations are performed.

That is, when a plurality of tiles are closely arranged side by side on a floor base or an existing floor to finish a tiled floor, the side surfaces of the protective films of the adjacent tiles abut each other, and For a tile placed at the edge of a tiled floor, the side surface of the protective film of the tile abuts a partition such as a wall forming the outer peripheral edge of the tiled floor. Therefore, even if the protective film of each tile can be peeled off from the tile main body, it is preferable because the protective film does not peel off when a person walks on the floor. Furthermore, even if the floor surface on which the tile of the present invention is constructed is cleaned by spraying water, it is difficult for water to seep out from the joints between the tiles to the lower part, and the tile body is made of a material having a water-absorbing property. However, it is possible to prevent water absorption from the side by the protective film, and it is also possible to prevent the tile body from warping due to water absorption.

Furthermore, when the lower surface portion of the protective film is covered, the lower surface portion of the protective film is pressed by the weight of the tile body by placing the tile of the present invention on the floor base surface or the existing floor surface. Even if the protective film of each tile is peelable from the tile body, the protective film can be more effectively prevented from peeling from the tile body, and the waterproofing effect of the tile body is further enhanced. It is preferable because it is excellent.

Next, the protective film can be appropriately selected according to the tile installation location and durability performance. For example, polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polychlorinated vinyl (PVC), polycarbonate ( PC), polyamide, acryl, polyurethane, fluorine and other resins, or a film of a copolymer of these, etc. be able to. Further, a multilayer film may be used for imparting additional functions such as scratch resistance, durability and antistatic property.

The thickness of the protective film can be appropriately selected depending on the place of use and durability, but is preferably from 0.01 mm to 1.0 mm. If the thickness of the protective film is less than 0.01 mm, there is a high possibility that the film will be broken during coating, and the durability during use will be low, which is not preferable. On the other hand, if the thickness of the protective film exceeds 1.0 mm, the durability of the film will be improved, but the cost of the film will increase and the workability of covering the tile body will decrease. . Also, the joints between the tiles may be widened, which may impair the aesthetic appearance. Furthermore, it is not preferable to cover even the lower surface of the tile body because the horizontality of the tile may be impaired.

In addition, the method of fixing the protective film to the tile body so that it can be peeled off can be any method that creates unnecessary irregularities that may hinder construction, peels off during construction, or does not peel off during use. good. Examples of the fixing means include a method using an adhesive, an adhesive, an adhesive tape, or the like.

As a method of fixing the protective film to the tile body, for example, an adhesive or a pressure-sensitive adhesive that can easily peel off the protective film can be used. The type of the adhesive may be a material having adhesiveness or tackiness under heating, pressure, or room temperature, a reactive adhesive such as a two-component type, or an adhesive. As a specific type, an acrylic type, a silicone type, a rubber type, a urethane type, a polyester type or the like can be appropriately selected. The bonding or adhesive strength is preferably from 0 :! to 4. O kg / 25 mm width (JISZ0237). 0.1 mm: ₂ 72 5111 111 If the width is less than 5111111, the film may peel off during transportation, construction, or use. At this time, peeling cannot be easily performed, and the film may be broken, which is not preferable because the peeling workability is reduced. The method of applying the adhesive may be any method such as spraying, brushing, gravure coating, etc., and may be applied to an object to which the adhesive or adhesive is applied, a protective film, a tile body, or the like. May be applied to both of them. The range of application may be applied to the entire coating portion or may be applied partially. For example, regarding the upper surface of the tile main body, it may be applied to the entire upper surface, may be applied in the form of a line or dots, and the peeling work may be performed by providing a portion to which no adhesive or adhesive is applied. Gender can be improved. However, it is preferable to completely apply to the end. Otherwise, the protective film may peel off during construction or use.

For example, when a heat-sensitive adhesive is used as the adhesive, the tile is only covered with the protective film after applying the heat-sensitive adhesive to the protective film and / or the tile body. Since the protective film is not fixed to the main body, the position of the protective film with respect to the tile main body can be changed, and the protective film can be positioned with respect to the tile main body. Then, by heating the protective film and the tile body, the protective film is detachably fixed to the tile body with a heatable adhesive.

In this manner, when the protective film is detachably fixed to the tile body, as the heatable adhesive, for example, an adhesive made of a thermoplastic resin such as an acrylate ester, or an acrylic emulsion paste can be used. Alternatively, any heatable adhesive can be used.

When covering the tile body with the protective film, a plurality of tile bodies may be continuously coated and adhered to a continuous sheet-like film, and then cut into individual tiles of the present invention, or may be formed into a predetermined shape in advance. The film may be cut, shaped into a three-dimensional shape corresponding to the shape of the tile body, and then coated on each tile body.

Also, cut the cut film appropriately so that the protective film does not partially overlap with the tile body covered. Is preferred. In other words, if the shape of the upper surface of the tile body is a square, the protective film is cut into a square shape larger by the thickness of the side surface of the tile body and, when covering the lower surface, by the amount of coverage of the lower surface. The upper surface of the tile body is located at the center, and cuts are made from the four corners of the protective film to the four corners of the part where the upper surface of the tile body is located. It is preferable to form a coating after removing the portion to reduce the coating work. Also, when covering the top, side, or bottom of the tile body, do not use an adhesive or adhesive to cover the tile body, but use a shrink film, for example, to make it peelable by hot air or the like. It may be fixed. Further, the tile body may be coated by vacuum forming. This makes it easier to peel off the film and tile because there is no adhesive or adhesive on the tile body, and is also preferable in terms of reuse of the tile body and recycling of the film.

In addition, when a multilayer film having a function such as scratch resistance is not used as a protective film, the surface of the protective film may be applied before or after the protective film is coated on the tile body. A functional layer such as a protective film may be provided.

If, for example, a protective film is provided on the surface of the protective film, the protective film is protected, so that the durability of the protective film can be further improved. Thereby, the replacement period of the tile of the present invention can be lengthened, and it can be used without trouble even in places where there are many walks or where oil or the like is easily spilled on the floor.

Also, by providing an antistatic film, it can be used even in a clean room where static electricity is avoided.

Such a functional layer is provided by applying a resin having a desired function or a resin obtained by adding various additives and the like to the surface of the protective film by spraying or brushing. Alternatively, the above components may be kneaded together when producing a protective film. For example, as a protective film, urethane Acrylic resin material not reinforced by acryl, Urethane reinforced acryl resin material, Fluorine material, Urethane resin, Epoxy resin, Silicone material (Mixed material of alkoxysilane, N-propyl alcohol and aluminum chelate compound Etc.), inorganic materials such as silicon-based materials (silicon glass), and ceramic-based materials can be appropriately selected and used. In the case of another functional layer, a binder resin composed of an acrylic resin, a urethane resin, an ethylene resin, or the like, and an antistatic agent, an inorganic substance that generates a negative ion, or the like may be appropriately selected. . The tile body used in the tile of the present invention can be applied as long as it has no warpage due to aging and has no problem as a laying floor material, and the material and structure can be appropriately selected. it can. For example, it may be a laminated structure such as existing tiles or a single-layer structure. Examples of materials include synthetic resins such as polychlorinated vinyl, polyolefin, polyurethane, and polycarbonate; inorganic materials such as ceramics, stones, and various metals; synthetic wood made of synthetic resins and wood; composite materials thereof; and laminated materials. Can be used. The shape is basically a plate-like body such as a rectangle or a square, but may be irregular in terms of design and the like. In addition, it is possible to produce a tile body of irregular shape according to the shape of the construction surface. Furthermore, the construction may be performed in various combinations depending on the shape of the construction floor. The size is substantially the same as a commonly used laying tile, and one side may be about 200 to 100 mm. If it is too large, it is not preferable because it causes inconvenience in workability and transportation. In addition, the thickness is preferably about 2 to 10 mm.If the thickness is less than 2 mm, unevenness of the floor material construction surface appears on the tile surface as it is and not only impairs the appearance but also impairs the appearance. However, the contact surface between adjacent tiles becomes smaller, and the weight of the tile itself tends to be lighter. On the other hand, if it exceeds 10 mm, the weight of the tile itself increases, which is not preferable in terms of transportability, workability, workability of coating and peeling. Note that the end of the tile body may be And can be chamfered as appropriate.

The protective film may be colored or transparent and colorless, translucent, or opaque, and may have a specific display such as a pattern or character printed thereon.

If the protective film is opaque, the tile body cannot be seen through the protective film, so there is no need to provide a special coloring layer or pattern layer on the top surface of the tile body. It can be used regardless of front and back, making it easy to create the tile body.

If at least the top surface of the protective film is transparent or translucent, a wide variety of tiles can be made by combining the color and pattern of the tile body with the color and pattern of the protective film. Become. For example, if the top surface of the tile body is a white base and a mosaic pattern is provided on it, and the protective film is a colored transparent film, even if there is only one type of tile body, the same mosaic pattern of the number of colors of the protective film It is also possible to change the atmosphere at the same construction site, even if the same tile body is used simply by changing the color of the protective film.

Also, instead of providing a pattern or text directly on the upper surface of the tile body, a sheet member on which the pattern or text is printed may be interposed between the protective film and the upper surface of the floor tile body. At this time, it is preferable that the sheet member is smaller than the size of the upper surface of the tile, and a portion where the protective film and the upper surface of the tile body are in direct contact is provided on the periphery of the upper surface of the tile body. Also, the pattern or character provided on the protective film, the tile body, etc. may be a character, a pictogram, a picture, a figure, a pattern, or a combination of at least two of these. But it's fine. The concept of painting includes photographs, CG images, etc.

In the tile of the present invention, when the used protective film is peeled from the tile body and the new protective film is coated on the tile body, the same type of protective film is not used. For example, the worn transparent protective film can be peeled off from the tile body having a pattern on the upper surface, and can be covered with an opaque protective film instead. In addition, when the worn protective film is peeled off from the tile body and a new protective film is fixed to the tile body instead, the upper surface of the peeled protective film and the upper surface of the tile body are separated. In the meantime, if the sheet member on which the sign is displayed is intervened, the sign is placed between the upper surface of the new protective film used in place of the peeled protective film and the upper surface of the tile body. The displayed sheet member may or may not intervene. When a sheet member is interposed, the sheet member may be the one used for the protective film before being peeled off, or may be another display member.

The tiles of the present invention can be easily removed from the construction surface because they are laying down when the flooring needs to be stained or repainted at the shop where it was constructed, and new tiles can be constructed. Can be. The removed tiles are collected by a collection company and transported to factories, etc., and after peeling off the protective film, if there is no damage to the tile main body, the tile main body is directly covered with a new protective film, and the new tile of the present invention is removed. Shipped again as tiles. In this case, a method in which the tile of the present invention is purchased and constructed by the contractor, and the used tile is discarded as waste and collected and used as in the case of the conventional floor material may be used. However, this is one of the merits of the tiles of the present invention, which is effective only in the reuse of the tile body and is not preferable in terms of the recovery efficiency.

Another advantage to eliminating the need for coating operations, such as regular floor protection Wakkusu, preferred distribution methods tiles possible and to have _c present invention in order that the exchange of tile itself instead is rented also Is preferably a leased article.

For example, if the tile of the present invention is a rental contract, the owner or user of the store or the like may prepare a store having only a floor construction surface where no floor material is constructed by new or refurbished. The initial capital investment costs can be reduced. At the stage when the floor construction surface is prepared, a contract is made with a rental contractor of the tile of the present invention, and the tile of the present invention is licensed to the rental exclusive business. Will be carried out by the worker. Needless to say, the rental fee paid at this time is lower than purchasing flooring. If, at the time of the contract, the tile replacement period, etc. of the present invention is determined in consideration of the access status of people at the store, etc., the owner or user of the store etc. will usually be It does not require a cleaning contract for the application, but instead of waxing, it can be replaced regularly or irregularly with new inventive tiles.

In addition, even if the flooring is partially damaged due to an accident or the like, it can be easily replaced by contacting a rental specialist, etc., which is an advantage in that respect.

Furthermore, it is possible to respond to custom-designs, etc. by simply printing patterns and characters on the protective film, or by interposing a sheet member on which patterns and characters are printed, so that it can respond to seasons and events. It can be easily and inexpensively changed to a floor.

The above described the advantages from the user's standpoint, but by distributing the tiles of the present invention under such a contract, it is possible to collectively use used tiles, not as general waste, but through rental-only contractors. The ability to recover tiles makes it easier to reuse the tiles themselves, greatly increasing the cost advantage.

In addition, in the case where the protective film is exhausted due to people walking on the tile according to the present invention, the protective film of the tile arranged at a place where a large amount of walking is provided on the tiled floor is used. It wears out more quickly than tiles that are placed in areas with fewer lands. For this reason, when the protective film of a tile placed in a place with a large amount of walking is worn out, remove this tile from the floor base or the existing floor, and place a protective film on the tile body in advance at this point. Removing and relocating the releasably secured replacement tiles can be an effective and efficient way to maintain the entire tiled floor.

In addition, when the protective film of the tile placed in a place with a large amount of walking was worn out, this tile was placed in a place with a small amount of walking. It may be exchanged for a Dile. In this way, the amount of consumption of the protective film for the tiles can be averaged, and the period of time required to replace the protective film for the tiles that have been placed in a high-walk area with a new protective film can be delayed. Can be. Alternatively, it is also possible to cope with the tiles arranged at the place where the amount of walking is large and the tiles at the place where the walk amount is small so that the replacement time of the new tile is different.

In the maintenance method according to the present invention, in the case of a tile that has been removed from the floor foundation because the protective film has been worn, the protective film is peeled off from the tile main body, and a new protective film is peeled off from the tile main body. As a result, the tile can be reused as a replacement tile to replace a tile with a worn protective film.

Therefore, according to the maintenance method of the present invention, a recycling system for reusing the tile body can be produced.

In the above-described maintenance method according to the present invention, the work of peeling the protective film of the tile removed from the floor substrate from the tile body and the work of detachably fixing a new protective film to the tile body are as follows. Generally, it can be performed at a tile manufacturing factory or a tile repair factory. This makes it possible to efficiently replace a worn protective film with a new protective film for a large number of tiles.

If tiles are subject to a lease or rental contract, a large number of tiles removed from multiple tiled floors may be removed from each tiled floor site to a tile manufacturing factory or a tile repair factory. To replace the worn-out protective film with a new protective film on the tile body so that many tiles can be used as replacement tiles. The work of storing the tiled floor until it is taken out to the site and the work of taking it out can be done efficiently and at low cost as a centralized and comprehensively managed system work. . The present invention described above can be applied to both the case of a standard tile having a standard size and shape and the case of producing a variant tile having a size and shape different from the standard tile depending on the shape of the construction surface and the like. Applicable to

Further, the present invention is applicable to tiles used for various floors such as store floors, office floors, public facility floors, and exhibition floors. Further, the tile of the present invention can be applied to the floor surface on which the existing floor material has been applied. As a result, it is possible to reduce the cost of managing the floor of a rental house or the like. The target floor may be the floor of a building or the floor of a building such as an underground mall. The floor may be a double floor in which electric wiring and the like are laid. Further, the floor may be a floor that can be finished only with tiles, or a floor that can be finished with tiles and floor finishing members other than tiles such as carpet tiles and mud removal mats.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The tiled floor described below is a convenience store floor. Also, tiles made mainly of plastic (hereinafter referred to as plastic tiles) were used.

Figure 1 is an overall plan view of the floor of this combination store. The floor is surrounded by a concrete wall 1 and a glass wall 2, and is accessed by an entrance 3 provided in a part of the glass wall 2. The ground floor is formed by casting concrete, and a large number of plastic tiles 20 and one mud removing mat 100 are simply placed on the floor ground without bonding to the floor ground. The floor is finished as a plastic tile floor. Therefore, these plastic tiles 20 and mud removal mats 10

0 have become a thing of every bedding type, _c Note underfloor ground is detachable, plastic tiles 2 0 all shown in FIG. 1 is a planar shape square, large listen and shape It is a standard type plastic tile that has become a standard type.If the overall floor shape of the floor is irregular, such as a triangle or trapezoid, the standard type plastic tile 20 and the plane shape is a triangle or rectangle. And the size and / or shape are standard plastic The floor is finished using a different type of plastic tile than the black tile 20.

The above plastic tiles 20 and mud removal mats 100 are subject to lease or rental contracts.

Various installations are installed on the floor shown in Fig. 1, and these installations include product shelves 4 to 7 arranged along the concrete wall 1 and separate from the concrete wall 1. There are merchandise shelves 8 to 11 installed on the floor, wagon-shaped merchandise display stands 12 and 13, and an accounting counter 14 arranged close to the entrance 3.

FIG. 2 is a longitudinal sectional view of the plastic tile 20 when it is placed on the floor substrate 15. The plastic tile 20 is composed of a tile main body 30 and a protective film 40 fixed releasably to the surface of the tile main body 30. The tile body 30 is mainly made of chloride chloride, and is formed by laminating and fixing an underlayer 21, a glass nonwoven fabric layer 22, an intermediate layer 23, and a surface layer 24 in order from the bottom. . The protective film 40 is formed of polyethylene terephthalate. In addition, the protective film 40 may be formed of any synthetic resin such as polypropylene, polyethylene, polyvinyl chloride, and polycarbonate.

FIG. 3 shows the protective film 40 before being placed on the tile body 30. The protective film 40 has an upper surface portion 4 OA having a square shape in plan view, and four side portions each connected to the upper surface portion 40 A on each side of the upper surface portion 40 A. 40 B, and on each side of the side surface portion 40 B opposite to the upper surface portion 4 OA, a side surface portion 40 B and four lower surface portions 40 C connected to each other. The upper surface portion 40A has the size and shape corresponding to the upper surface 30A of the tile body 30 and the side surface portion 40B has the side surface 30B of the tile body. 0 C is smaller than the lower surface 30 C of the tile body 30 even when the four lower surface portions 40 C are combined.

In addition, each lower surface portion 40 C is combined with these lower surface portions 40 C. Then, the size may be the same as the size of the lower surface 30 C of the tile body 30.

The protective film 40 is formed by punching from a film material, and has a boundary between the upper surface portion 40A and the side surface portion 40B and a boundary between the side surface portion 40C and the lower surface portion 40C. The line is bent, whereby the boundary line of the protective film 40 becomes a bending line so that the protective film 40 can be bent freely.

A predetermined back surface of the protective film 40 before being covered with the tile main body 30, for example, a back surface of the upper surface portion 4 OA and a back surface of the side surface portion 40 B, and a back surface of the lower surface portion 40 C are heated. A heat-sensitive adhesive that produces adhesiveness is applied. The heatable adhesive contains an acrylic ester which is a thermoplastic resin, and the heatable adhesive may be appropriately selected from acryl emulsion glue and the like.

Thus, the protective film 40 coated with the heat-sensitive adhesive on the predetermined back surface is placed on the tile body 30 while being bent at the respective bending lines, whereby the upper surface portion 40A is covered with the tile body 30. After the upper surface 30 A, the side surface portion 40 B are brought into face-to-face contact with the side surface 30 B of the tile body 30, and the lower surface portion 40 C are brought into face-to-face contact with the lower surface 30 C of the tile body 30 C, respectively. As shown in FIG. 4, a plastic tile 20 composed of a tile body 30 and a protective film 40 is passed between a pair of heating rotary rollers 45 arranged opposite to each other in a roller-type heating and pressing device. Thus, the protective film 40 is pressed against the tile main body 30 and the heatable adhesive is heated, and the protective film 40 is fixed to the tile main body 30 so as to be peelable by the adhesive.

When the protective film 40 is detachably fixed to the tile body 30, the peel strength can be appropriately adjusted depending on the type of the adhesive or the pressure-sensitive adhesive. It can also be performed by adjusting the temperature at which the heatable adhesive is heated by the heating rotary roller 45, or by adjusting the amount of the heatable adhesive applied to the back surface of the protective film 40. As described above, the work of applying the heat-sensitive adhesive to the back surface of the protective film 40, the work of covering the tile film 30 with the protective film 40, and the pair of rollers as shown in FIG. The work of fixing the protective film 40 to the tile body 30 by pressing the protective film 40 onto the tile body 30 while heating the heatable adhesive in step 5 is shown in Fig. 5. It is carried out at the plastic tile manufacturing plant A indicated by. In this factory A, a large number of standard plastic tiles and deformed plastic tiles described above are produced in this way, and these plastic tiles are transported to the site B where the plastic tiles are laid, and the site B is used for these plastic tiles. It is used to finish the floor by being detachably placed on the floor surface of the floor. One of the sites B shown in FIG. 5 is the convenience store shown in FIG.

In the convenience store shown in Fig. 1, the mud removal mat 100 is located near the entrance 3 so that a person entering the store walks on the mud removal mat 100, Most of the mud and dust that has adhered to human footwear is removed by the mud removal mat 100. However, a small amount of mud and dust that still adheres to the footwear infiltrates the interior of the combi-enstore where a number of plastic tiles 20 are arranged together with the footwear. For this reason, after the new opening of the convenience store, the upper surface portion 40 A of the protective film 40 of these plastic tiles 20 starts to be gradually consumed.

The amount of consumption of the upper surface portion 40 A is large in the plastic tile 20 A arranged in the area C close to the accounting counter 14, which is a place with a large amount of walking, out of a large number of plastic tiles 20. Small plastic tiles 20 B located in area D near merchandise shelves 6 and 7, which are far from entrance 3 and have less walking.

Plastic tiles placed in area C 2 Protective film for OA 40 When the upper part of the OA reaches a certain amount, or when the upper part reaches a certain amount. But not pre-determined After a certain period of time, remove the plastic tile 2 OA in area C and the plastic tile 20 B in area D from the floor base, and place the plastic tile 20 A in area D and the plastic tile 20 B in area C. Replace these plastic tiles with 2 OA and 20 B. This replacement work is performed by detachably placing the plastic tiles 20A and 20B on the floor base surface.

As a result, the protection film 40 in which the upper surface portion 40A is greatly worn out in the area C is substantially the same as repairing the protection film 40 at the convenience store site, and this repair work is performed in a convenience store. It can be easily done in a short time without restricting the whole installation or a predetermined area in the convenience store from entering for a fixed time or a fixed period.

As described above, elapsed time after performing replacement of plastic tiles 2 0A and 20 B of the area C and D, depletion of these plastic tiles ² OA, 20 B top portion 4 of the protective film 40 of the OA However, when it has progressed so that it cannot be replaced with another plastic tile 20 used on the floor of the convenience store, the replacement plastic tile 20 previously manufactured at the factory A in FIG. Carry the same number as B to the convenience store in Fig. 1. Then, the plastic tiles 20A and 20B are removed from the floor substrate, and the replacement plastic tile 20 is placed on the floor substrate instead.

The same work as described above can be performed by transporting a large number of replacement plastic tiles 20 from the factory A to the convenience store and storing them in advance, and using only the required number of the replacement plastic tiles 20. You may go.

In addition, among the plastic tiles 20 other than the plastic tiles 2 OA and 2 OB or the plastic tie ^ / 20 A and 20 B shown in FIG. Protective film 40 Plastic tile with damaged upper surface 40 A When this occurs, the plastic tile 20 is replaced with a replacement plastic tile 20.

By performing these operations, the work of repairing the protective film 40 of the plastic tiles 20 used on the floor of the convenience store and the work of repairing the protective film 40 on the floor of the convenience store were actually carried out. Has not been carried out, but it is virtually the same as repairing on the floor. In addition, these operations can be easily performed in a short time while continuing to operate the convenience store.

Then, the plastic tile 20 removed from the floor substrate is transported to the factory A, where the work of peeling the worn protective film 40 from the tile body 30 is performed manually or automatically by a machine. Be done. Then, the tile body 30 from which the protective film 40 has been peeled off is covered with a new protective film at the factory A. This covering work is performed in the same manner as described above by applying a new protective film with a heat-resistant adhesive applied to the surface. This is performed by covering the film 30 on the tile body 30. When covering the tile main body 30 with the protective film, for example, the tile main body 30 is fixed on the guide rail, and the protective film is brought close to the tile main body 30 along the guide rail and brought into contact therewith. The alignment may be performed by the following.

Then, by passing the obtained plastic tile between the pair of heating rotary rollers 45 in FIG. 4, the new protective film is fixed to the tile main body 30 so as to be peelable.

The plastic tiles manufactured at Factory A in this way are stored at Factory A until they are transported to each site B in Figure 5 as replacement plastic tiles. Then, at the site B, when a plastic tile with the worn upper surface 4 OA of the protective film 40 is generated, the replacement plastic tile is carried to the site B and the upper surface 40 A of the protective film 40 is produced. Are replaced with worn plastic tiles.

As described above, the plastic tile 20 according to the present embodiment is obtained by covering the tile main body 30 with the protective film 40 in a releasable manner. Therefore, when the protective film 40 is worn out, the protective film 40 can be peeled off from the tile body 30. Instead, a new protective film can be peelably covered on the tile body 30. As a result, it becomes substantially the same as when the worn protective film 40 is repaired, and this repair work can be easily performed.

In addition, since the protective film 40 covers the side surface 30 B of the tile body 30, each plastic tile 20 is placed on the floor base surface 15 as shown in FIG. When these plastic tiles 20 are juxtaposed and juxtaposed, the side portions 40B of the protective film 40 of the adjacent plastic tiles 20 abut each other. As for the plastic tile 20 placed at the edge of the plastic tile floor, the side wall 40 B of the protective film 40 of the plastic tile 20 forms the outer peripheral edge of the plastic tile floor. Abut the partition. For this reason, even if the protective film 40 of each plastic tile 20 can be peeled off from the tile body 30, in other words, the plastic tile 40 can be attached to the tile body 30 with a heat-sensitive adhesive. Even if the adhesive strength is small, it is possible to effectively prevent the protective film 40 from peeling off from the tile body 30.

Further, in this embodiment, since the protective film 40 has the lower surface portion 40 C that covers the lower surface 30 C of the tile main body 30, the plastic tile 20 is placed on the floor base surface 15. And the lower surface portion 40 C of the protective film 40 is pressed by the lower surface 30 C of the tile body 30, and the lower surface portion 40 C is pressed down by the weight of a person riding on the plastic tile 20. Therefore, peeling of the protective film 40 from the tile body 30 can be more effectively prevented.

Furthermore, since the upper surface 3OA of the tile body 30 is covered by the upper surface portion 40A of the protective film 40, the upper surface portion 4OA of the protective film 40 is colored or a pattern is formed on the upper surface portion 4OA. By displaying them, it is necessary to color the tile body 30 or to display patterns etc. on the tile body 30. No need. Therefore, the manufacture of the tile body 30 can be facilitated and the cost can be reduced.

In this embodiment, a heat-sensitive adhesive that generates an adhesive force when heated is used as an adhesive for detachably fixing the protective film 40 to the tile body 30. The protective film 40 is not fixed to the tile body 30 simply by covering the film 40 with the tile body 30. Therefore, the work of changing the position of the protective film 40 with respect to the tile main body 30 to the correct position can be performed, and the work of heating the adhesive after positioning the protective film 40 with respect to the tile main body 30 is performed. Thereby, the protective film 40 can be fixed to the tile body 30 in a releasable manner.

In addition, since the heating operation of the heat-sensitive adhesive in the present embodiment is performed while pressing the protective film 40 against the tile body 30 with the pair of rollers 45, the pressing force causes the protective film 40 to be heated. The upper surface portion 40 A can be fixed to the upper surface 3 OA of the tile main body 30 without any gap between them.

At the site B of the floor with plastic tiles, when a plastic tile 20 with the protective film 40 worn down occurs, the plastic tile 20 is removed from the floor base 15 and the tile body 3 Since the plastic film 20 on which the protective film 40 is peelably covered is placed on 0, the worn protective film 40 at this point is substantially repaired in a short time. Convenience stores on the floor of plastic tile floors do not need to be closed for a certain period or for a certain period of time.

Also, of the plastic tiles 20 sent to the factory A to cover the tile body 30 with a new protective film in place of the worn protective film 40, it is placed at the location D where walking is small until just before this. Plastic tile 2 OA was initially placed at location C with high walking, and then replaced with plastic tile 20 B located at location D with low walking. These plastic tiles with 2 OA The wear amount of 20 B can be averaged, and the period until the protection film 40 of the plastic tile 2 OA is replaced with a new protection film can be delayed.

Furthermore, since each plastic tile 20 is subject to a lease contract or a rental contract, it is necessary to peel off the worn protective film 40 from the tile body 30 or to add new work to this tile body 30. It is possible to complete a system for work for repairing the protective film 40, such as work for covering the protective film, as a unified and comprehensively managed system.

In addition, by making each plastic tile 20 the subject of a lease or rental contract, a large number of plastic tiles 20 are transported from each plastic tile floor B to plastic tile manufacturing factory A. Work or rebuilding a large number of plastic tiles 20 as replacement plastic tiles by releasably covering a new protective film on the tile body 30 in place of the worn protective film. The task of storing the replacement plastic tile until it is carried out to the site B of each plastic tile floor and the work of taking it out are reduced as work of a centrally and comprehensively managed system. It can be done efficiently at low cost. In addition, work to use the protective film 40, which has been peeled off and worn from the tile body 30, as a material for the production of a new protective film is also performed in a centralized and comprehensively managed system. Work can be performed efficiently at low cost.

Also, in Factory A, the new protective film is detachably replaced on the tile body 30 in place of the worn protective film 40, so that the tile body 30 is reproduced as a tile body of a replacement plastic tile. Used, the tile body 30 can make a recycling system.

FIG. 6 shows another embodiment for applying pressure to the tile main body 30 while heating the protective film 40 having the heat-resistant adhesive applied to the back surface. In this embodiment, a press-type heating / pressing apparatus including a heating lower plate 46 and a heating upper plate 47 is provided. Is used. The tile body 30 covered with the protective film 40 coated with the heat-sensitive adhesive is placed on the lower heating plate 46, and then the lower heating plate 47 is lowered, whereby the protective film 40 is lowered. Then, the tile body 30 is pressurized while heating the heatable adhesive. As a result, a plastic tile 20 in which the protective film 40 is detachably fixed to the tile body 30 with the heatable adhesive is completed.

According to this embodiment, the protection film 40 can be peelably fixed to the tile body 30 only by moving the heating upper plate 47 up and down once, so that the roller-type heating and pressing device shown in FIG. Work efficiency can be improved.

In the embodiment of FIG. 7, when the tile body 30 is passed between a pair of heating rotary rollers 48 constituting a roller-type heating / pressing device, a roll-type material serving as a material for a protective film is used. The film material 50 is also placed on the tile body 30 and passed between a pair of rollers 48, so that the film material 50 is heated and adhered to the back surface of the film material 50. It is fixed to the tile body 30 so that it can be peeled off. In addition, the film material 50 is continuously fed out from the roll portion 51, whereby the film material 50 can be peeled off to a plurality of tile bodies 30 fed between the pair of rollers 48 at an interval. Fixed sequentially.

The display may be provided with a display other than characters, or may be a display without a display.

FIG. 11 shows a plastic tile 2 OD with a display according to another embodiment. This plastic tile 2 OD is composed of a tile body 30, a transparent or translucent protective film 40, a top surface 30 A of the tile body 30 and an upper surface portion 4 OA of the protective film 40. It consists of a sheet member 80 intervening between them and displaying characters 70. The sheet member 80 is formed of a thin material such as a synthetic resin film or paper.

Also in this embodiment, since the characters 70 can be visually recognized on the upper surface of the plastic tile 20D through the transparent or translucent upper surface portion 40A of the protective film 40, the plastic tile 2OD can be used for advertising, announcements, etc. Can be used as a medium for notifying the notification items.

When replacing the protective film 40 of the plastic tile 20D with a new protective film at the site A shown in Fig. 5, the sheet member 80 is kept between the tile body 30 and the new protective film. Intervening, a sheet member on which a character different from the character 70 is displayed may be intervened, a sheet member on which a display object other than the character is displayed may be interposed, or the sheet member may not be intervened. Is also good.

According to this embodiment, the display material such as characters is displayed on the sheet member 80 which is a separate member from the protection film 40. Since there is no need to provide a display on 0, the production of the protective film 40 is facilitated.

In addition, in order to fix the upper surface portion 4OA of the protective film 40 to the upper surface 3OA of the tile body 30 so as to be peelable with a heating adhesive, the size of the sheet member 80 must be smaller than the upper surface 3OA. Just do it. Further, even when the size of the sheet member 80 is the same as that of the upper surface 3OA, the side portion 40B of the protective film 40 is attached to the side surface 30B of the tile body 30 with a heat-sensitive adhesive. By peelably bonding, the protective film 40 can be peelably fixed to the tile body 30. Subsequently, another embodiment according to the present invention is shown in FIGS.

The plastic tile 20 in FIG. 12 is composed of a tile body 30 and a protective film 40 fixed detachably to the tile body 30. The protective film 40 is viewed from the top of the tile body 30.
