Description

DETAILED DESCRIPTION OF THE INVENTION Although thinned wood or small-diameter wood such as Japanese lumber, which has been used to create prismatic pillars with a standard diameter of 10.5 cm, is inexpensive, it has little utility value.

However, due to the recent shortage and high cost of wood resources, attention has been paid to the use of small-diameter trees, and research has been conducted on gluing them together and reusing them as larger diameter trees. In terms of durability and strength, perfect laminated wood has not yet been manufactured.

In view of the above-mentioned drawbacks of the conventional method, the present invention aims to achieve uniform and strong adhesion of all materials, which is the life of small-diameter laminated wood. By driving a wedge-shaped wedge with an equilateral or isosceles triangular surface and two sides coated with adhesive, all materials are bonded uniformly and firmly, and laminated wood whose upper surface is the same plane can be produced in large quantities at low cost. It has been made possible.

The wedge-shaped lamina used in the present invention has an equilateral or isosceles triangular cross section as shown in FIG. An example in which a pentagonal wedge-shaped lamina is used will be described.

Reference numeral 1 is a trapezoidal lamina whose cross section is ladder-shaped and is made of small-diameter materials such as thinned wood or backwood used in the present invention.

2 is a wedge-shaped laminar whose cross section is an equilateral triangle, and as shown in Figure 8, it is formed one fin larger than the height of the trapezoidal laminar L, and after applying adhesive on its two sides 8 and 4, it is placed in parallel. Numerous trapezoidal laminars 1.1 Space between each other Fji
Insert into 6.

The right end portions 6 of a large number of parallel trapezoidal laminars 1 are received by a vertical frame 7, and the left end portions 8 are pressed by a side pressure press 9 to form a border, and then pressed from both sides by a hot press plate 10.

At this time, the tips 11 of each of the trapezoidal laminars 2 are crushed to make the adhesion with the trapezoidal laminars 1.1 on both sides even more uniform and strong, and to protect the upper surfaces of each trapezoidal laminar 1 and the wedge-shaped laminar 2. A coplanar assembly board 12 is produced.

As shown in FIG. 6, a large number of the laminated boards 12 are piled up in opposite directions and bonded together to produce a block-shaped laminated timber 18.

This laminated timber 18 has become very strong, but in actual use it has become even stronger because it is cut vertically and used as a plate or square timber. In the figure, reference numeral 14 indicates a finger joint of the laminated plate 12.

The lateral pressure of the lateral pressure press in the present invention is due to the fact that the lower corners of the trapezoidal laminars 1.1 on both sides touch at one point.
Since the entire trapezoidal laminar 1 and the entire rust-shaped laminar 2 are pressed equally without causing the entire trapezoidal laminar 1 to float or decreasing the lateral pressure as it advances toward the right end, the adhesion is uniform and strong. be able to.

Furthermore, since the wedge-shaped laminar 2 descends straight, the adhesive can be bonded uniformly and stretchably without digging into the oblique sides of the trapezoidal laminars 1.1 on both sides or being obstructed by joints.

On the other hand, since the cross-section of the one-sided rust-shaped lamina 1 is an equilateral triangle,
It can be applied uniformly over the entire surface using the same coating machine, and can accurately apply large quantities of tens of thousands of coats per day, making it extremely efficient and economical as it saves on adhesive.

Although the case where the wedge-shaped laminar 2 with an equilateral triangular cross-section is used has been described above, the same operation and effect can be achieved even when the other wedge-shaped laminar with an isosceles triangular cross-section shown in FIG. 1 is used.

As mentioned above, the present invention completely eliminates the adhesion defects of laminated wood made by gluing together small-diameter materials, which was considered to be the best in the past, and enables uniform and strong adhesion, which is the lifeblood of laminated wood. It has a long-term effect.
