In one unit block (1), one wood material (3) is laminated on one rigid board (2), but not limited to this, and several wood pieces are combined on one rigid board (2). May be configured.

In this embodiment, the unit block
The cement-based high-rigidity plate (2) constituting (1) is, for example, a plate material obtained by pressing and molding a kneaded material of cement and an inorganic particulate material having a smaller particle diameter than the cement (for example, microsilica). Or an asbestos slate board, but is not limited to this, and any cement-based board may be used. As described above, when using inorganic particulate matter having a smaller particle size than cement, the plate material (2) is formed at a high density,
High rigidity can be achieved.

The woody piece (3) converts hydrophilic hydroxyl groups such as cellulose, hemicellulose, and lignin, which are the main components of the woody material (3), to hydrophobic and hardens to harden and impart dimensional stability. Chemical treatment or injection of a low-molecular synthetic resin such as phenol, urea, melamine or the like having a molecular weight of 200 or less is injected. By injecting this low-molecular-weight synthetic resin, the cell walls constituting the wood are covered with the resin to maintain the elasticity of the wood, etc., and the synthetic resin film becomes a barrier to impart waterproofness, insect repellency, and antiseptic properties to the cell walls. It is.

The high-rigidity plate (2) constituting the unit block (1) is rectangular (square or rectangular) and is basically made of wood (3).
It is the same size as. The connection between the high-rigidity plate (2) and the wooden material (3) is made by a physical connecting means such as an adhesive or a screw or a bolt.

The unit block (1) is, in the embodiment of FIG.
In the center, four square unit blocks (1a) are combined, and the periphery thereof is surrounded by a rectangular unit block (1b). Each of the blocks (1a) and (1b) is a synthetic resin strip (4 ). The belt-shaped body (4) may have a cutout (5) for draining water. This is effective in causing rainwater and the like flowing into the joints (6) and (6a) to flow down to the road surface side. still,
The combination of the unit blocks (1) is not limited to the illustrated embodiment.

The wooden tile (A) in which a plurality of unit blocks (1) are connected has a similar synthetic resin strip (4a) on at least two of the outer side surfaces. (When the strip (4a) is provided on the entire outer surface, the inner strip (4)
Of the width (T) of (T) is used. This is because the uniform joints (6) and (6a) are formed by the synthetic resin strips (4) and (4a) when a plurality of the wooden tiles (A) are laid.

The synthetic resin strips (4) and (4a) are formed on the outside of the unit block (1) and the wooden tile (A).
Wood pieces (3) placed at a fixed distance above and below
And a high-rigidity plate (2). This is to prevent the intrusion of water, dust, etc. into the binding layer when the wood tile (A) is used on the outside such as a sidewalk, and to form mold joints (6) (6a) at the same time. is there.

The woody tile (A) of the present invention obtained as described above is usually provided on a ground layer (9) such as a ground surface as shown in FIG. The cement-based high-rigidity plate (2) is laid so as to be a lower layer via the.
This laying can be performed by a method known in the art. As the mortar layer (8) for the sidewalk,
What is referred to as “pasmol” or “mol resin” is used.

In the wooden tile (1) having the above structure, the wooden material (3) to be the upper surface is subjected to the above-mentioned chemical treatment for hydrophobization or resin coating of the cell wall by injecting a low-molecular synthetic resin from the surface. Water and fungi can be prevented from invading, and even if fungi invade wood due to cracking or trauma, erosion of cell walls by these fungi can be prevented.

Further, since the lower surface of the wood material (3) layer is covered with a cement-based high-rigidity plate (2) having poor water absorption, not only water and fungi from the lower surface can be prevented, but also Cement-based high rigidity board with high dimensional stability (2)
The swelling of the wood (3) layer due to water absorption during rainy weather and water sprinkling is extremely small because the wood is dimensionally stabilized because it is fixed and integrated with the layer, resulting in high rigidity Peeling between the board and the wooden material is prevented. Further, as described above, since the wood material (3) has been subjected to the hydrophobic treatment and the resin injection, the volume change due to dryness is controlled in combination with the binding force of the plate material (2), and the wood material (3) layer is formed. It is also possible to prevent cracks and defects.

Further, since the wooden material (3) is integrally laminated on the high-rigidity plate (2), the specific gravity of the whole becomes high, and the unit blocks (1) are made of a synthetic resin strip (4) having flexibility with each other. ), So that, for example, when laid on a sidewalk, it is possible not only to prevent lifting due to external forces such as the weight of a person walking on the wooden tile (A), but also
(5) Even if there is unevenness, it can be applied smoothly.

Further, when a wooden tile (A) having a notch (5) is laid in the strips (4) and (4a), the adjacent unit blocks (1)
Rainwater smoothly flows down to the underlayer (8) through the sandy ground (6) in between, and does not accumulate on the tile surface.

[0025]

According to the present invention, since a wooden material is laminated on a cement-based high-rigidity plate of a unit block, and the unit blocks are connected by a flexible synthetic resin strip, a high rigidity plate is obtained. Since the rigid plate increases the specific gravity of the whole, and is bent by the flexible belt-like body, there is an advantage that the adhesion to the road surface is increased and the floating can be prevented. In addition, the dimensional stabilization by the hydrophobic treatment and resin injection of the wood material layer and the control of the wood material layer deformation control by the high-rigidity board layer can eliminate the peeling due to the reduction of the stress on the adhesive layer, and from the laying surface. There is also an advantage that desorption can be prevented. In addition, the presence of the upper layer of the wood material layer can maintain the soft light reflection and appearance unique to wood. In addition, since at least at least two sides of the wooden tiles are provided with elastic synthetic resin strips, uniform joints are formed between the large tiles,
There is an advantage that the boundaries between the large tiles do not appear and the appearance is improved. Furthermore, since the elastic synthetic resin band is arranged at a certain distance above and below the outer side of the unit block, the bonding surface is formed when the gap formed between the unit blocks enters into the gap formed between the unit blocks. And the adhesion between the two is improved. In addition to this, since gaps are formed above and below the belt-like body, there is an advantage that the belt-like body is easily bent in accordance with the unevenness of the laying surface, and the flexibility is improved.
