BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings and showing its function and effect.

In the case of the first aspect of the invention, the plate-shaped laminated material body A which is the product of the present invention can be used as various building members. For example, by arranging the plate-shaped laminated material body A as a building floor material or a building wall material on a lower ground such as a floor or a wall, a floor surface or a wall surface can be constructed.

In addition, since the plate-shaped laminated lumber body A has a structure in which a large number of cross-sections 2 at which the conduits are cut and exposed are arranged side by side at least, the front and back surfaces of the bamboo material are arranged in the front and back directions. Unlike the product, it gives a very unusual and beautiful appearance (surface) appearance due to the cross section of the mouth piece 2. Moreover, since the conduit is arranged in the front and back direction, this conduit has a breathable function that functions as a ventilation hole. The laminated lumber body A becomes a certain laminated lumber body A, and the bamboo laminated lumber body is extremely practical because moisture and air are satisfactorily distributed through the conduit in the front and back directions of the laminated lumber body A.

Further, it has been confirmed that the laminated material body A of the present invention has a characteristic that the sound is very easily reflected due to the exposed conduit on the surface. Therefore, for example, when the laminated body A of the present invention is used as a constituent material of an audio device such as a speaker box or a floor / wall constituent material of an audio equipment room such as a music hall, it is excellent in reverberation and has a high acoustic effect. Speakers and music halls will be created.

In addition, in this way, the cut end 2 of the cut bamboo material 1
According to the configuration in which the plates are arranged in the front-back direction of the plate-shaped laminated body A,
The cut bamboo material 1 can be used even if it is short, and therefore the laminated wood body A can be configured by using even fine bamboo cutting material, so that the material can be manufactured extremely economically without wasting it.

Further, when a large number of the cross-sections 2 are arranged side by side on the surface, the laminated material body A having a higher surface strength can be obtained as compared with the conventional product in which the front and back surfaces of the bamboo material are arranged in the front and back directions. It has been confirmed that it will be a laminated lumber body with an excellent structure that has excellent durability and improved service life.

Further, since the conduit is exposed at least on the surface of the laminated material A, the coating material such as a pigment easily penetrates into the laminated material A through the conduit, so that the surface coating work can be speedily performed. Similarly, since liquid chemicals such as antifungal agents and insect repellents easily permeate into the laminated lumber A through the conduit, the chemical application work can be performed speedily, and the chemicals can be deeply and evenly spread through the conduit. Because of the ease of penetration, the drug will act more effectively.

When the laminated wood body A is coated with resin, the coating material enters the conduit, and the coating material in the conduit is cut bamboo material 1
Thus, the laminated body A having higher strength is completed.

Further, charcoal powder or bamboo charcoal can be press-fitted or rubbed into the conduit so as to be enclosed. With such a construction, it is possible to use the laminated wood A or bamboo charcoal having the deodorizing effect of charcoal. For example, the laminated lumber body A having a forest bathing effect is completed.

In the case of the invention of claim 2, first,
A large number of cut bamboo materials 1 obtained by chopping bamboo in the length direction are arranged in parallel so that the cut-out exposed cross-sections 2 of the conduit are arranged in the same direction to form a block-shaped assembly 3.

Then, the block-shaped assembly 3 is cut in a direction parallel to or inclined with respect to the cutout section 2 of each cut bamboo piece 1 to cut and expose a conduit from the assembly 3 to expose the cutout section 2. Are cut out to form plate-like bodies arranged in the front-back direction, and the cut-out plates are formed into a plate-like laminated laminated body B having a large number of the cross-sections 2 arranged side by side on at least the surface.

Also in the plate-shaped laminated material body B according to the second aspect, the same operational effect as that of the plate-shaped laminated material body A according to the first aspect of the invention is exhibited.

Further, in particular, when the block-shaped laminated body 3 is cut in the direction of inclination to form the plate-shaped laminated body B, as shown in FIG.
Since the joining area by the joining means such as adhesion is large, the laminated body B having higher strength can be obtained.

Embodiments of the present invention will be described with reference to the drawings.

1 to 4 show the first embodiment, FIGS. 5 and 6 show the second embodiment, FIG. 7 shows the third embodiment, and FIG. 8 shows the fourth embodiment.

The first embodiment will be described.

In this embodiment, a large number of cut bamboo materials 1 obtained by chopping bamboo in the length direction are arranged in parallel so that the cross-section 2 of the mouth where the conduit is cut and exposed is arranged in the front and back directions, and at least on the surface thereof. It is configured as a plate-shaped laminated body A in which a large number of cross-sections 2 are arranged side by side.

To be more specific, first, a thin strip 10 (see FIG. 1), which is a strip of bamboo cut in the lengthwise direction and has a curved cross section, is cut and exposed by a conduit (not shown). Cut bamboo material 1 with a square cross section by cutting all four sides leaving the cross section 2
(See FIG. 2). Further, the drawing shows the case where the short cut bamboo material 1 is formed.

Then, a large number of the cut bamboo pieces 1 are arranged in parallel so that the cross-sections 2 of the mouth where the conduit is cut and exposed are arranged in the front and back directions, and the adjacent surfaces of the cut bamboo pieces 1 arranged in parallel are adhered to each other. It is configured as a plate-shaped laminated wood body A (see FIG. 3) in which a large number of the cross-sections 2 are arranged side by side on the front and back surfaces.

According to this embodiment thus constructed, the plate-shaped laminated body A has a structure in which a large number of the cross-sections 2 are arranged on the front surface and the back surface, so that the front and back surfaces of the bamboo material are arranged in the front and back directions. Unlike the conventional product that is placed, it creates a very unusual and beautiful surface appearance due to the cross section 2 of the mouth, and because the conduit is arranged in the front and back direction, this conduit functions as a ventilation hole. As a result, the laminated timber body A having the air permeability is obtained, and the moisture and the air are satisfactorily distributed through the conduit in the front and back directions of the laminated timber body A.

Further, in this way, the cut end 2 of the cut bamboo material 1
Since the cut bamboo material 1 can be used without problems because the structure is arranged in the front and back direction of the plate-shaped laminated lumber A, it is possible to construct the laminated lumber A by using even fine bamboo cutting materials. As a result, there is no waste of material and it can be manufactured extremely economically.

Further, when a large number of the cross-sections 2 of the mouthpiece are arranged in parallel on the surface, the surface strength of the laminated lumber A is higher than that of the conventional product in which the front and back surfaces of the bamboo material are arranged in the front and back directions. It was confirmed by the trial manufacture experiment by the applicant, and the laminated material body A having excellent durability and improved service life was constructed.

It has been confirmed by a trial experiment by the applicant that the laminated material body A has a characteristic that the sound is very easily reflected due to the exposed conduit on the surface. When the assembly A of this embodiment is used as a speaker box constituent material or a floor wall constituent material of an audio facility such as a music hall, an excellent speaker and a music hall having a very high echo effect and a high acoustic effect are produced. Was confirmed to be completed.

Further, since the conduit is exposed at least on the surface of the laminated lumber A, the paint such as the pigment can easily penetrate into the cut bamboo material 1 (the laminated lumber A) through this conduit as compared with the conventional product. The surface coating work can be performed speedily, and similarly, liquid chemicals such as antifungal agents and insect repellents easily penetrate into the laminated body A, so that the chemical coating work can be performed faster than the conventional products. At the same time, since the drug easily penetrates deeply into every corner via the conduit, the drug acts more effectively than the conventional product.

Further, when the laminated wood body A is resin-coated, the coating material enters the conduit, and the coating material in the conduit is dried so as to reinforce the cut bamboo material 1. The laminated material body A having higher strength is completed.

Therefore, for example, if a resin coating is applied so as not to fill all of the conduits existing in the laminated body A, the uncoated (unfilled) conduits exert a ventilation function, so that the strength is further improved and the air permeability is improved. Laminated timber body A that holds together is completed.

In the case where the laminated lumber body A of this embodiment is used for an application in which air permeability is unnecessary, the laminated lumber body A is used.
A resin coating may be applied so as to block all of the conduits, and if configured in this way, the laminated material body A having even higher strength is completed.

Further, charcoal powder or bamboo charcoal can be press-fitted or rubbed into the conduit so as to be enclosed. With this structure, it is possible to use the laminated wood A or bamboo charcoal having the deodorizing effect of charcoal. For example, the laminated lumber body A having a forest bathing effect is completed.

Is less likely to be deformed than the laminated material body A configured by being arranged in the same direction.

Further, in each of the laminated layer portions of the upper layer portion A ₁ , the middle layer portion A ₂ and the lower layer portion A ₃ of the laminated structure A of the laminated structure of this embodiment, the cross section 2 of the mouth end is polymerized and joined. With this configuration, the upper, middle, and lower layers of the conduits communicate with each other, and moisture and air can flow through the conduits in the front-back direction of the laminated body A.

Further, in the present embodiment, the front and back surfaces of the large number of cut bamboo pieces 1 are juxtaposed so that they are adjacent to each other, and the adjacent cut bamboo pieces 1 are adhered in parallel so that the front and back surfaces thereof are opposite to each other. The laminated lumber body A of is constituted.

Therefore, by configuring in this way,
