[Problems to be Solved by the Invention] Conventionally, forests in Japan have many small-diameter lumber compared to foreign countries, and the topography has few flatlands and many sloping lands, so many bent and lumbered lumbers are released. Bent materials were used for beam materials in old architecture, but in the current construction method, precutting has become widespread and there are few carpenter beams that can use bent materials, and there is a tendency for only straight timber that can be easily blackened. Bending is no longer used. In addition, the size of wood from the forest is 3 to 4 m, and only wood is taken, and wood that is less than 3 m is scrap wood, and it is left untouched without being used together with bending materials, The amount is quite large, and it is one of the causes of the high cost of timber upstream. Further, it cannot be said that the method disclosed in the above publication sufficiently exhibits the humidity control function which is the original function of wood, and in particular, the proposal of the technology established as a commercial product for wide plates such as wall materials. Not only that, but also the use of bent materials and scraps has not been proposed.

BEST MODE FOR CARRYING OUT THE INVENTION Next, the most preferred embodiment of the present invention will be described. 1 to 10, 1
Is a log of small-diameter trees cut from the forests that make up scrap wood,
2 is a bent wood log small diameter tree 1 is used as it is because it is almost a straight material, but the bent material 2 is a bent portion A-
Cut the A-line so that there are no breaks and divide into straight materials 3 and 4 for use. It should be noted that the small-diameter tree 1 and the bent material 2 are cut to an appropriate size such that the length can be obtained so that the longest possible straight material can be obtained, so that the thinned wood can be effectively used.
In this manner, the lumbered small-diameter tree 1 and the straight woods 3, 4 are lumbered into a relatively short plate veneer 5 having a predetermined width and thickness, and after being dried in a known manner, a predetermined thickness, for example, 9 mm. Planar processing was performed on the plate, and multiple veneers 5 were bad-joined in the fiber direction.
So that they do not overlap with each other in the direction of the fiber so that they are stacked vertically, apply a commercially available adhesive to the joint surface of the veneer 5 so that the thickness is about 50 cm and the length is about 2 m, and then stack the required number of layers on top and bottom. , Laminated square bar 7 by applying hot pressure or cold pressure in a known manner
Process into

Next, after curing this square bar 7, the square bar 8 is formed in parallel with the longitudinal direction of the square bar so as to have a cutting allowance by a planer and a thickness that allows for the thickness. Next, the grained plate 8 is processed by a planer so as to have the thickness of the veneer 5. When this processing is completed, the grained board 8 shown in FIG. 5 is cut at a line B-B and a line C-C at right angles to the fiber direction and processed into three plates of a predetermined width, which are side surfaces in the fiber direction. Then, a well-known adhesive is applied, and hot or cold pressure processing is performed in a well-known manner to process the regular square grain parallel plate 9 having a predetermined length as shown in FIG. On the other hand, the lumber 10 having a predetermined length and width pressure is cut from the straight wood portion of the thinned small diameter tree, and after drying, a commercially available adhesive is applied to the side surface in the fiber direction, and the length is 3 m to 4 m and the width is 450 mm to 850 mm. Block material with a width of about millimeter 11
Then, the width of the veloc material 11 is widened to a predetermined thickness, for example, 9 mm to form a wide width strip plate 12.
(See Figures 7 and 8)

After this width-and-groove plate 12 is dried, it is processed into a predetermined width and thickness with a planer, and a well-known adhesive is applied to the lower surface of the width-and-square board 12 and the upper surface of the square-grain board 9. After that, as shown in FIG. 9, the both are superposed so that the fiber directions cross each other and bonded by hot pressure or cold pressure to form a wide composite strip 13 having a predetermined length and width. In the embodiment shown in FIG. 9, a wide width strip plate 12 is adhered on the regular square grain parallel plate 9, and the wide strip plate 12 is bonded to the upper and lower surfaces of the regular square grain parallel plate 9 as shown in FIG. It is also possible to polymerize and bond 12 and process into a wide composite strip 14 having a predetermined size. In this way, the obtained composite wide width board can be used for building materials such as wall boards and ceiling boards which have excellent moisture control effect by showing grain or wood grain on the surface, and as shown in FIG. If it has a three-layer board structure, it can be used as a door material, a panel material and a furniture material. Further, a movable dedicated press machine for carrying out the present embodiment has also been developed, and by using this, the steps up to finishing the long composite wide width board can be performed consistently.

[0009]

As will be understood from the description of the above embodiment, the present invention cuts a straight material portion from a thinned small-diameter tree or bent material which has not been used so far, and cuts a straight material portion with a relatively short predetermined width. Saw to a plate veneer having a, this is dried and vertically spliced together and the seams are vertically stacked with the phase shifted in the fiber direction and bonded, and processed into a laminated square bar of a predetermined length, and This is sawed vertically in the longitudinal direction so that the grain can be seen on the surface, and a square grain plate having a thickness almost the same as the thickness of the above wide veneer is made, and further cut into multiple pieces with the required width. To form side-by-side veneer sheets with the required number of square timbers lined up side by side, side by side in the fiber direction. The above-mentioned grain-cut parallel veneer from the block material which is a horizontal connection of several timbers with A wide composite strip having the same thickness was laminated and adhered to one or both sides of the grain-cut parallel veneer so that the fiber directions intersect each other so that a long composite wide strip can be created. However, it is possible to exhibit the following excellent effects.

That is, the present invention can be utilized not only as a building material suitable for an era in which trees cannot be wasted because it uses the edge portion of thinned wood that has not been used so far and is used as it is. Muku, which has excellent temperature control and moisture absorption functions, is basically processed by sawing, and the grain is arranged side by side in the horizontal direction and the grain in the vertical direction and the grain is parallel in the vertical direction on both sides. Since a single plate and a wide lateral strip are laminated and bonded in the direction of fibers, they can be used for interior and exterior building materials as well as furniture materials. Further, in the present invention, since it is made of solid wood, it can be said that it is a building material that is exactly suitable for a time when it is not possible to waste wood, and it is more suitable than a building material that is processed by mixing wood with powder or fine particles and mixing it with resin. It can be provided as a building material suitable for the age of natural materials, which has an excellent advantage in terms of environment where resin usage is extremely low.
