Description

[Detailed Description of the Invention] The name of the invention is that thin wood that is not normally used as construction material, such as thinned wood from forest management, can be used as a core material without losing its original strength while remaining as a log. This is an attempt to assemble square timbers with relatively little processing.

Thin timber such as thinned timber has traditionally been used as scaffolding material at construction sites, but in recent years it has been displaced by metal pipes and the market price has fallen significantly, contributing to a decline in motivation for forest management. I'm getting used to it. This has led to the effect of attracting mountains and reducing the results of afforestation, and is even being discussed as having an impact on water resources.

It is believed that the present invention will pave the way for the effective use of thinned wood and contribute to resolving these problems, and will also be sufficient to create a new small industry in depopulated villages.

First, the key points of the log are cut down to the most effective extent using a lathe, as shown in Figure 1.

Separately prepare a square piece of wood and cut the center part for the first cutting part (a)
Hollow out the center with a light that fits closely to the outer light.

These square timbers shall be assembled in advance so that they can be divided into two equal parts from the center without damaging the lightness of the right hole of the central hollow.

Cut this hollowed-out square lumber and log to a length that fits the cut part (A), tie the wood at the center (Fig. 2), and fit it into the cut part (A) by gluing it. Do as shown in Figure 3. Furthermore, the prepared plate material (FIG. 4) is glued and crimped on all sides to form a square material as shown in FIG. 5. In this case, the plate material does not necessarily have to be attached on all four sides depending on the purpose. In addition, if you use a finishing method in which the shape of the remaining part of the polished part (a) of the log material is not limited to a cylindrical shape, the shape of the fitting member should be made to match the shape of the polished part. good. It goes without saying that the fitting member used in this description may be split from the beginning.

[Brief explanation of drawings]

Each figure is a perspective view. Figure 1 is a log with key points cut out. FIG. 2 shows a fitting member for the cut portion in FIG. 1. FIG. 3 is a diagram showing the fitting member shown in FIG. 1 fitted into the part shown in FIG. 2. Figure 4 shows the board material to be attached to the four sides of Figure 3. Figure 5 is a completed drawing.

Claims (1)

[Scope of Claims] A log material is shaved at key points, a fitting member that tightly fits into the cut portion is fitted on the outside to form a corner, and a board is pasted on the outside of the fitting member. A method for producing laminated wood by attaching it to a square lumber.
