た床構造に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bamboo laminated flooring made of a combination of bamboo materials cut out from bamboo such as Moso bamboo and bamboo, and is used as a flooring material for buildings such as ordinary houses, public houses and gymnasiums. The present invention relates to a bamboo laminated flooring material and a floor structure using the same.

果も高い。2. Description of the Related Art Conventionally, there are various types of building materials, particularly floor materials, such as natural wood and plywood. Plywood has various shapes and structures, and there is also one using bamboo. As can be seen from the fact that bamboo has been used as a ruler since ancient times, it has low elasticity, excellent durability, toughness, and a high deodorizing effect.

いった利点がある。Conventionally, bamboo materials A obtained by horizontally and vertically grinding Moso bamboo to form a plate having a thickness of several mm, a width of several cm, and a length of several 10 cm to 1 m are arranged vertically as shown in FIG. There is a bamboo laminate B in which bamboo materials A to be bonded are pressure-bonded to each other using an adhesive. Since the bamboo laminate B has a bamboo pattern on the surface C, it has the appearance and texture unique to bamboo, has a good appearance, has the elasticity unique to bamboo, is hard to bend or crack, and has little deflection. The advantage is that the vibration width is small and the moisture resistance is excellent.

あり危険でもあった。The bamboo laminate B shown in FIG.
Since all of a large number of bamboo materials A are arranged in the same vertical direction, the adhesive strength against the vertical force is weak even if they are bonded with an adhesive. Therefore, when this bamboo laminate B is used as a flooring material, the seam F of the bamboo material A is applied by the vertical force applied to the floor.
Is easily peeled or distorted. In particular, when used on floors in gyms and other places where intense exercise is performed, intense vibrations are applied, so that the adhesive is more likely to be peeled off and distorted, making it difficult to walk, and in some cases, the bamboo projections coming out of the cracks There was a danger of sticking to the foot, which was also dangerous.

ことがあった。In FIG. 10, since the bamboo material A is bonded to a plywood (for example, plywood) D different from bamboo, the bonded bamboo material A and the plywood D have different expansion ratios, moisture absorption rates, and the like. For this reason, the adhesive may be peeled off or distorted with the passage of time.

In the case of mm, it is desirable to form three pieces at intervals of 290 mm from the viewpoint of workability and the stability of fixing the bamboo laminated flooring 10. The nail hole 11 is for preventing the bamboo material 1 from breaking when the nail is driven. When nails are driven by an air gun, the bamboo material 1 does not break even if there is no nail hole 11, so the nail hole 11 is not necessarily required in this case. Incidentally, 16 in FIG. 1 (a) is a bamboo node.

cm, bamboo with a thickness of about 8 mm) is horizontally ground at intervals of about 1 m into several pieces (usually 3 to 4 pieces). 2. The bamboo that has been horizontally ground is vertically ground to a width of about 3.3 cm using a bamboo splitter. Thereby, a plurality of bamboo materials 1 (FIG. 8) are formed. Inspect the bamboo material 1 and eliminate defective products. 3. Bleaching, disinfection and mold control Bamboo has inherently the drawback of mold.
Therefore, in the present invention, the bamboo material 1 is bleached and sterilized, and a fungicide treatment is also performed. The antifungal treatment is excellent in fungicidal properties, so that it is hardly corroded even when laid in a place with a lot of humidity and moisture. Bleaching is performed by immersing the bamboo material 1 in a sodium hypochlorite solution at room temperature (30 ° C. to 40 ° C.) for 5 minutes. Bleaching can also be carried out by boiling in sodium hydrogen peroxide. At the same time as bleaching, it kills parasites and stops mold. Since the sodium hypochlorite solution is an alkaline solution exhibiting a strong oxidizing effect, the bamboo material 1 pulled up therefrom is thoroughly washed with water and wiped off. After this, a sorting inspection is performed and the surface colors of the materials are made uniform. 4. Bamboo Dimension Selection Before the bamboo material 1 dries, the unnecessary side and surface portions are shaved off. Thereby, the width, thickness, and the like of the bamboo material 1 are determined. 5. Surface polishing The surface of the bamboo material 1 formed as described above is polished. In the polishing, fine polishing is performed after rough polishing. This polishing need not always be performed. 6. Low temperature dehumidification drying The bamboo material 1 polished as described above is dried and finished by a low temperature dehumidification method. In this drying, the temperature is maintained at 90 ° C. to 100 ° C. by a dehumidification method in combination with a boiler, and the bamboo material 1 is dried to a moisture content of 100% within a range of 38 hours to 7 to 8%. In this case, the drying starts from the inside and spreads to the outside. Thereby, even if the bamboo material 1 touches water, it can always be maintained at 7 to 8%. After this finishing, the bamboo material 1 is re-inspected. The low-temperature dehumidification drying makes it difficult for the bamboo material 1 to be distorted or cracked by drying after being laid on the floor, and to be hardly deformed after being laid.

After the polishing, a paint finish is performed. For this coating, an oil-modified one-pack type polyurethane resin paint (UV paint) is used. The processing color tone in this case can be a desired color, but it is desirable to use white or brown in order to make use of the color tone of bamboo. Either color can be glossy or matte finish. This coating material is cured by irradiating ultraviolet rays, has a hardness of about 4H, and is hardly scratched on the surface. An oil-modified two-pack type polyurethane resin paint can be used for the paint finish. 12. An example of the finish dimensions of the bamboo laminated flooring 10 is the thickness T = 1.
