DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden tile and its mounting structure. More particularly, the present invention relates to a wooden tile that can be used in places where rainwater or water is likely to be splashed, and a mounting structure thereof.

[0002]

2. Description of the Related Art Wooden tiles are suitable as floor materials because of their moderate cushioning properties, soft light reflection and appearance. However, wood materials are apt to be attracted to insects, are easily decayed by absorbing moisture, have poor durability, and have insufficient dimensional stability, so that it is difficult to use them around water. In view of the above, it is not common to use wood materials outside the house such as a veranda where rainwater is splashed, or in a place where water is easily splashed such as a dressing room. In general, at the present time, water is sealed between tiles by a caulking material. For example, in the construction of conventional wooden tiles, after installing the tiles, the joints are subjected to waterproofing by caulking, but this work first puts a protective tape leaving the joints to prevent dirt on each wooden tile, After filling the joints with the caulking material, the protective tape is removed, but the water sealing process is a very complicated operation.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to use a wooden tile utilizing the characteristics of the above-mentioned wooden material, which has sufficient durability even in a place where water is easily splashed and which is easy to construct. It is to provide a tile mounting structure.

And a process of injecting a low-molecular synthetic resin into the wood layer to cover the cell wall, or a process of combining these.

In the former treatment, an acetyl group or the like is mentioned as a hydrophobic substituent. In the latter treatment, it is preferable to use a low-molecular synthetic resin, for example, phenol, urea, melamine and the like having a molecular weight of about 200 or less. In addition, in the preservation and insect repellent treatment in the wooden tile (1), the entirety of the wooden layer (3) is usually applied to the wooden layer (3), but in some cases, the surface layer may be targeted.

[0008] The water-swellable mineral particles in the sheet material (4) containing water-swellable mineral particles used in the present invention may be any mineral particles that absorb water and expand in volume. And, for example, bentonite. Bentonite is preferably used in the present invention because it expands 8 to 10 times due to water absorption. However, it is not limited to this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments, but the present invention is not limited thereto. Embodiment 1 FIG. 1 is a perspective view of an example of a wooden tile (1) of the present invention.
In the figure, the wooden tile (1) has a honeycomb structure layer (2) as a lower layer, and a wooden layer (3) is bonded and integrated thereon,
In addition, two adjacent sides on the side circumference of this woody layer (3)
A sheet material (4) containing water-swellable mineral particles is stuck.

The wood board (2) of the wood tile (1) is rotten by replacing and modifying hydrophilic hydroxyl groups such as cellulose, hemicellulose and lignin, which are main components of wood, with hydrophobic groups by chemical treatment. It is difficult and the dimensions are hard to get out of order,
Alternatively, a low-molecular resin, for example, a low-molecular synthetic resin such as phenol, urea, or melamine having a molecular weight of 200 or less is injected, and the cell wall is covered with the resin.

Bentonite is used as the water-swellable mineral particles in the sheet material (4). The particle size of this bentonite is adjusted almost uniformly, and the bentonite is densely packed in the sheet material (4).

For bonding the honeycomb structure layer (2) and the woody layer (3), for example, an epoxy-based adhesive, a butyl rubber-based adhesive sheet, an asphalt- based adhesive sheet, or the like is used.

The wooden tile (1) constructed as described above
As shown in FIG. 2, on the concrete foundation layer (5),
An adhesive layer (6) is provided with a predetermined thickness, and while the adhesive layer (6) is still fluid, the lower honeycomb structure layer is formed.
The lower end portion of (2) is buried and laid, but if the sheet material (4) containing water-expandable mineral particles is provided only on two sides, the adjacent wood layers (3) However, the wooden tiles (1) are always laid so as to interpose the sheet material (4) containing water-expandable mineral particles in consideration of the orientation of each woody tile (1). When provided on the entire circumference, there is no need to consider the direction.

In the mounting structure (7) constructed as described above, a hardened film is formed on the cell wall of the woody layer (3) with a low molecular weight synthetic resin, so that the antiseptic and insect repellent effects are exhibited, and at the same time, the waterproofness is improved. Is given. On the other hand, the wooden board (2)
Hydrophilic hydroxyl groups such as cellulose, hemicellulose, and lignin, which are the main components of wood, may be substituted or modified by hydrophobic treatment with a chemical treatment.Because there is no hydrophilic group, there is no bond with water. It is hard to rot and has insect repellent effect.

Since the sheet material (4) containing water-expandable mineral particles is interposed in the gap (8) between the wood tiles (1), even if water permeates between the wood tiles (1). However, moisture is absorbed by the water-expandable mineral particles in the sheet material (4), and does not penetrate into the honeycomb structure layer (2) through the side circumference of the wooden tile (1). Further, the mineral particles that have absorbed water swell and further close the tile gap (8), so that water can be sealed efficiently. In addition, since mineral particles shrink by drying,
Even if water enters the honeycomb structure layer, it evaporates easily during drying.

The wood tiles (1) are all laid at the same level by adjusting the amount of embedding into the adhesive layer (6) at the lower end of the lower honeycomb structure layer (2). Therefore, even if irregularities appear on the concrete foundation layer (5), the tile upper surface is always flush and flat.

[0026]

According to the present invention, since the lower layer is formed of the honeycomb structure layer, even if unevenness appears in the underlying layer, the amount of embedding of the lower end portion of the honeycomb structure layer into the adhesive layer can be reduced. By adjusting the level, the level is adjusted, and the upper surface of the wooden tile can be formed as a flat surface.

Further, since the wood tiles are adjacent to each other via the sheet material containing water-expandable mineral grains, the water sealing treatment between the wood tiles has already been completed. Therefore, the water sealing process is completed in the gaps between the tiles at the same time as the laying of the wooden tiles, so that the construction can be performed very easily.

Since the wood tiles are preserved and insect-proofed and the gaps between the tiles are sealed, the tiles can be used safely in rainwater or other places where water is likely to be applied.

Further, since the water-swellable mineral particles used are inorganic substances, there is no need to worry about generation of mold, deterioration or decomposition due to sunlight, etc. as compared with starch-based or resinous swelling agents, and a stable sealing for a long period of time. Water can be realized. Further, since the mineral grains shrink when dried, an appropriate gap can be secured between the wooden tiles during drying, and the underlayer can be dried.
