To glue. This veneer 5
For this, wood such as hardwood or conifer may be used.
By laminating in this way, the structural laminated material 10 is obtained. In the stacking of the split bamboo layers 4, the split bamboos 2 are stacked so that the pulling and arranging directions are sequentially orthogonal to each other, and further, the surface of the structural laminated material 10 is made into the veneer 5. By doing so, it is possible to obtain the structural laminated member 10 which has the strength required as the structural member despite using the bamboo material, and which is lower in cost and stronger in temperature change than the conventional structural laminated member. . The structural laminated wood of the present embodiment is suitable for use as a load bearing wall, and FIG. 2 shows only a part thereof.
In this case, the single plates 5 and 5 located on the outermost surfaces in the drawing are the front and back surfaces of the wall. In the figure, the split bamboo layers 4 and the veneer boards 5 are alternately laminated one by one, but the present invention is not limited to this, and for example, two continuous veneer boards 5 and the split bamboo layers 4, or The two continuous split bamboo layers 4 and the single plate 5 may be sequentially and repeatedly laminated.

ある。Another embodiment of the structural laminated member 10 will be described with reference to FIG. 3A and 3B are perspective views showing another embodiment of the structural laminated member 10. FIG.
The structural laminated lumber 10 shown in (a) is a split bamboo 2 of each split bamboo layer 4.
The drawing directions are arranged in the same direction. Further, the structural laminated wood 10 shown in FIG. 3 (b) is formed by stacking a plurality of single plates 5 and split bamboo layers 4 so as to overlap each other. By doing so, it is possible to obtain the structural laminated material 10 which has the strength required as the structural material and which is lower in cost than the conventional structural laminated material and is resistant to temperature change. Then, when the split bamboo layer 4 or the veneer 5 having the desired length is obtained, the split bamboo layer 4 or the veneer 5 may be used as it is, but the split bamboo layer 4 with the desired length is obtained. Alternatively, when the veneer 5 cannot be obtained, a concavo-convex portion is formed at the end of the split bamboo layer 4 or the veneer 5 in the length direction, and the end faces of the split bamboo layer 4 or the veneer 5 are adhesively connected (finger). Adhesion by a joint, etc.), and the split bamboo layer 4 or veneer 5 of a long product having a desired length is formed and used. The structural laminated material 10 of the present embodiment is suitable for use as a pillar, and in this case, the longitudinal direction shown in FIG. 3 is used as the longitudinal direction of the pillar. In this case, if the veneers 5 and 5 are located on the outermost side in the stacking direction and the veneers are separately attached to both sides where the stacking is visible, the entire circumferential surface of the pillar becomes a veneer, which is aesthetically pleasing. Also, it is effective in improving strength.

ての用途を拡大することができる。Further, according to the structural laminated wood using the bamboo material according to the second aspect of the present invention, since the split bamboo formed into a flat shape by pressing with high temperature and high pressure steam is used, the split bamboo is sterilized. Also, the oil removing operation can be performed at the same time as the split bamboo forming operation, the production process is simplified, and the cost for producing the split bamboo formed on a plane is reduced. Further, since the cost of bamboo is generally lower than that of wood, it is possible to reduce the cost of the material by using bamboo, and since bamboo is more resistant to temperature changes than general wood, The material can be made resistant to temperature changes. Furthermore, since a plurality of split bamboos formed in a flat plate shape as described above and structural plywood are alternately laminated and laminated and adhered, when only split bamboos are laminated or a single plate made of split bamboo and lumber is used. It is possible to further improve the strength as compared with the case of stacking, and it is possible to expand the use as a structural material.

れる集成材の構造材としての使用を可能にしている。Further, according to the method for manufacturing a structural laminated lumber using a bamboo material according to the invention of claim 4, the bamboo material is cut so that its cross section becomes an arc shape, pressed by high temperature and high pressure steam, and then dried. By doing so, the split bamboo is formed into a flat plate shape, so that the work of sterilizing the split bamboo and removing oil can be performed at the same time as the split bamboo forming operation. As a result, the production process can be simplified and the production cost can be reduced. In addition, the split bamboo layers formed by this process are arranged in a plane, and the split bamboo layers and a plurality of laminated veneer timber or structural plywood are alternately laminated and bonded together. The strength can be improved as compared with the case of stacking, and the laminated wood produced by these steps can be used as a structural material.
