Description

  The present invention relates to a flooring joint structure in which flooring materials are joined to each other, a method of use thereof, and a maintenance method.

  Allergens such as mites and pollen cause atopic dermatitis and allergic rhinitis, and are regarded as social problems. As techniques for reducing such allergens, Patent Documents 1 to 3 disclose floor materials provided with an allergen reduction function (hereinafter simply referred to as allergen-reduced floor materials).

  Specifically, the allergen-reducing flooring disclosed in Patent Document 1 is for flooring topcoats, for example, by dissolving an anti-allergen agent (allergen reducing agent) of a water-insoluble polymer having a phenolic hydroxyl group in a photocurable paint. After obtaining the photocurable paint, it is obtained by applying the photocurable paint for flooring topcoat to the wooden flooring. The allergen-reducing flooring disclosed in Patent Document 2 is obtained by obtaining a paint formed from a curable resin composition containing an inorganic compound carrying an anti-allergen agent and then applying this paint to a wooden board. It is done. The allergen-reducing floor material disclosed in Patent Document 3 is an inorganic compound carrying an anti-allergen agent, an active energy ray-curable resin having two or more (meth) acryloyl groups, and 1 to 3 (meth) acryloyl groups. After obtaining a paint having a Tg of 100 ° C. or higher and an aliphatic hydrocarbon monomer having 1 to 2 (meth) acryloyl groups and having a viscosity at a coating environment temperature of 1500 mPa · s or less, It is obtained by applying this paint to a wooden board. That is, in these allergen-reducing flooring materials, a coating film containing an antiallergen agent is formed on the surface of the flooring material. For this reason, when the allergen in the air adheres to the floor material surface, the allergen is inactivated by the anti-allergen agent in the coating film.

(Configuration of flooring joint structure)
The flooring joining structure according to the embodiment of the present invention is installed in an indoor space and joins the flooring 1 and 1 to each other as shown in FIG. The flooring 1 is a rectangular or laminar shape made of a woody base material made of a single board such as plywood, MDF, hard board, particle board, single board laminate, or a composite board thereof. As shown in FIG. 1A and FIG. 2, in this embodiment, on the parallel end surfaces of the flooring 1, a female fruit 10 having a substantially U-shaped cross section and a male fruit that can be fitted to the female fruit 10. 11 and the floor materials 1 and 1 are joined to each other by fitting the female seed 10 and the male seed 11 of the adjacent floor materials 1 and 1 together. The floor materials 1 and 1 may be joined to each other by so-called jointing or the like.

  As shown in FIG. 1, the floor material 1, 1 is connected to each other at a joint 2 with an opening on the surface (upper surface) side of the floor material 1 (upward), and particulate allergens a such as mites and pollen. A hole-like reservoir portion 20 is formed. In this embodiment, the pool portion 20 is a narrow gap portion having a substantially hat-shaped cross section formed between the joint end surfaces 21 and 21 of the floor materials 1 and 1, and the back surface (lower surface) of the floor material 1. An opening 21 is also formed on the side (toward the lower side), and an inclined surface 21a is formed at the upper end portion of each joint end surface 21 so as to incline toward the opposite side to the joint end surface 21 as it goes upward. . When the inclined surface 21 a is formed on the joint end surface 21 in this way, the upper opening 20 a of the reservoir 20 becomes large, and the allergen a easily enters the reservoir 20 through the large opening 20 a.

On the inner surface of the reservoir 20, the coating films 3 and 3 containing the allergen reducing agent are formed by applying and fixing the coating containing the allergen reducing agent in advance. The coating material contains, for example, an ultraviolet curable resin as a main component. In the present embodiment, the coating material is applied to almost the entire surface other than the inclined surface 21a among both surfaces of the joint end surfaces 21, 21 of the floor materials 1, 1. In addition, a coating material may be apply | coated only to any one surface among both the joining end surfaces 21 and 21, and may be apply | coated only to upper vertical surface 21b, 21b among both the joining end surfaces 21 and 21. FIG. However, it may be applied only to the fitting part between the female fruit 10 and the male fruit 11 of the joint end faces 21 and 21. The paint is applied using, for example, a roll coater, a flow coater, a brush, or the like before the floor materials 1 and 1 are joined to each other.

  The allergen reducing agent is composed of a substantially spherical solid particle material or an aqueous solution material. In addition to the spherical shape, the shape of the allergen reducing agent may be other shapes such as a cylindrical shape and an elliptical shape.

  Examples of allergen reducing agents include polyphenols, proteolytic enzymes, organic compounds such as urea, fine particles provided with ionic functional groups, and compounds containing inorganic salts.

  The allergen reducing agent may be used as it is, or may be used by mixing with an acrylic resin, a polyester resin, an epoxy resin, or the like. Moreover, an allergen reducing agent may be used by a single type and may combine multiple types. What is necessary is just to select the allergen reducing agent used suitably according to the allergen a made into reduction object.

  A cushion material 4 made of an elastic sheet such as a nonwoven fabric, a foamed resin plate, or a rubber plate is adhered to the entire back surface of each flooring 1.

(Operation and usage of flooring joint structure)
Hereinafter, the operation and usage of the joint structure of the flooring 1 configured as described above will be described.

  As shown in FIG. 1A, the allergen a existing in the indoor space adheres to the surface of the flooring 1 or enters the pool part 20 and accumulates. Since the reservoir 20 is located at a position lower than the surface of the flooring 1, the allergen a is likely to accumulate. And since the coating material containing the allergen reducing agent is applied to the inner surface of the pool part 20 where the allergen a is accumulated, the allergen a reacts with the allergen reducing agent in the coating films 3 and 3, and the allergen a is sure. And inactivated efficiently. Furthermore, since the reservoir portion 20 is a narrow gap portion generated in the joint portion 2, the allergen a accumulated in the reservoir portion 20 is in close contact with the allergen reducing agent in the coating films 3 and 3, and the allergen a is the coating film. It becomes easier to react with the allergen reducing agent in 3, 3 more easily, and allergen a is inactivated more reliably and efficiently. In addition, since the paint containing the allergen reducing agent is applied to almost the entire surfaces of the joining end faces 21 and 21, the contact area of the allergen a with the allergen reducing agent in the coating films 3 and 3 is increased (specifically The contact area of the allergen a adhering to the surface when the coating film containing the allergen reducing agent is formed on the surface of the flooring 1 is about twice the contact area with the allergen reducing agent in the coating film. (See allergen a adhering to the surface of the flooring 1 shown in FIG. 1 (a))), allergen a is more reliably and efficiently inactivated.

  By the way, when a person walks on the flooring 1, the flooring 1 vibrates not only vertically but also horizontally, and accordingly, the joint 2 also vibrates vertically and horizontally. As a result, the allergen a accumulated in the reservoir 20 is agitated and moved in the reservoir 20, and the allergen a is likely to contact and react with the allergen reducing agent in the coating films 3 and 3, so that the allergen a is more reliable and efficient. Inactivated. Moreover, since the cushioning material 4 is provided in the back surface of each flooring 1, when a person walks on the flooring 1, between the part which is stepped on and the part which is not stepped on the flooring 1 among the flooring 1 A large deflection occurs. As a result, the amount of allergen a accumulated in the reservoir 20 in the reservoir 20 is increased, and the allergen a is more likely to contact and react with the allergen reducing agent in the coating films 3 and 3. It is reliably and efficiently inactivated.

(Maintenance method for flooring joint structure)
Hereinafter, the maintenance method of the joining structure of the flooring 1 configured as described above will be described.

  When time elapses after the use of the flooring 1 is started, the allergen a reducing function of the allergen reducing agent itself in the coating films 3 and 3 decreases, or as shown in FIG. When 3 and 3 are peeled off from the inner surface of the pool portion 20 (see white portions in the coating film 3), the allergen a reducing function in the pool portion 20 is lowered. Therefore, after the start of use of the flooring 1, the wax containing the allergen reducing agent is dropped and supplied to the reservoir 20 by, for example, waxing the surface of the flooring 1 with wax containing the allergen reducing agent.

  Examples of the wax include resin waxes such as urethane and acrylic, and aqueous waxes such as wax. The wax to be used is determined based on the material of the flooring 1. When the wax containing the allergen reducing agent is supplied to the reservoir 20, the wax spreads over the entire reservoir 20 because the viscosity is high, and as shown in FIG. 3B, the allergen reducing agent contained in the wax is the allergen reducing agent. It adheres to the entire inner surface of the reservoir 20 including the part where it has peeled off, and the allergen a reducing function in the reservoir 20 is regenerated. For this reason, the function of reducing allergen a in the reservoir 20 is maintained.

  Further, after the start of use of the flooring 1, as shown in FIG. 3 (a), the surface of the flooring 1 is wiped with an aqueous solution containing an allergen reducing agent, as shown in FIG. An aqueous solution containing a reducing agent may be supplied dropwise.

  When the aqueous solution containing the allergen reducing agent is supplied to the reservoir 20 in this way, the aqueous solution quickly penetrates into the reservoir 20 and the allergen reducing agent contained in the aqueous solution is reduced to the allergen reduction as shown in FIG. The agent is immediately fixed to the inner surface of the reservoir 20 including the part from which the agent has been peeled off, and the allergen a reducing function in the reservoir 20 is immediately regenerated. For this reason, the function of reducing allergen a in the reservoir 20 is maintained. Furthermore, since allergen a is easily dissolved in water, when an aqueous solution containing an allergen reducing agent is supplied to the reservoir 20, the non-inactivated allergen a accumulated in the reservoir 20 is dissolved in this aqueous solution, and this allergen a It reacts with the allergen reducing agent contained in the aqueous solution, and allergen a is inactivated more reliably and efficiently.

  Further, after the start of use of the flooring 1, as shown in FIG. 3A, a volatile solution such as alcohol containing an allergen reducing agent may be supplied dropwise to the reservoir 20 as necessary.

  When a volatile solution containing an allergen reducing agent is supplied to the reservoir 20 as described above, the volatile solution literally has a volatile property, so that the volatile solution quickly permeates into the reservoir 20 and volatilizes. The allergen reducing agent contained in is immediately dried. As a result, as shown in FIG. 3B, the allergen reducing agent contained in the volatile solution is immediately fixed to the inner surface of the reservoir 20 including the portion where the allergen reducing agent has been peeled off, and the allergen a in the reservoir 20 is The reduction function is played immediately. For this reason, the function of reducing allergen a in the reservoir 20 is maintained. Further, when a volatile solution containing an allergen reducing agent is supplied to the reservoir 20, the inactivation of the non-inactivated allergen a accumulated in the reservoir 20 is promoted by the volatile solution, and the allergen a Reacts with the allergen-reducing agent contained in the volatile solution, and allergen a is inactivated more reliably and efficiently.

  The allergen reducing agent used in this maintenance may be the same as or different from the allergen reducing agent applied in advance to the inner surface of the reservoir portion 20. Moreover, the allergen reducing agent may be used by a single type, and may combine multiple types.

(Other embodiments)
In the above embodiment, the reservoir 20 has a substantially hat-shaped cross section. However, the present invention is not limited to this. For example, the reservoir 20 is partitioned by the upper surface of the male fruit 11 and the upper vertical surfaces 21b and 21b of both the joining end surfaces 21 and 21. It is good also as a cross-sectional substantially rectangular shape opened only to one surface side.

  Moreover, in the said embodiment, although the cushioning material 4 is provided in the back surface of each flooring 1, this does not need to be provided. However, it is better to provide from the viewpoint of reliable and efficient inactivation of allergen a.

  The present invention is not limited to the embodiments, and can be implemented in various other forms without departing from the spirit or main features thereof.

  As described above, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. The scope of the present invention is defined by the claims, and is not limited by the specification. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
