Description

[Detailed Description of the Invention] (Prior Art and Disadvantages) What is the conventional method for assembling logs processed to have the same thickness on two and three sides?

The shape of the continuous lower log is processed into ha logs, and the wood frame is constructed.

The shape of each successive log is different, and each piece is processed differently.

Both the required four-manufacturing tool and the machining speed and accuracy were perfect.

For the above reasons, mass production and uniform processing at T:, etc. is a must.

Furthermore, when processing the upper log, the lower half of the log was cut off.

Most of the strong core wood was removed unnecessarily. Also, the processed shape of the L-shaped log.

Due to the difference of 2%, it was impossible to construct a wooden frame that could be converted from top to bottom, and there was no exchangeability for the B product.

(Purpose and structure) The purpose of this woodwork is to eliminate the drawbacks mentioned in E.2 Figure 1 is a plan view of the woodwork of a drum-sawn log.

Dot-dash line 1° to 2° vertically and 3” to 4° horizontally, the center line for the log 4. The point where each center line intersects at right angles is 9.

Six consecutive squares with 1234 angles form one overlapping part of the wooden frame.

The point is the center point of the square on the table.

Sides 1 to 2 and sides 3 to 4 are lines 1' to 2° line 3, respectively.
' to 4°.

It doesn't have to be parallel.

1 to 42 to 3 are square diagonal lines, respectively.

5-8 is 1-4.

6-7 are extension lines of 2-3, respectively.

It is desirable that the length of the negative side of the square be equal to the thickness of the log.

The second figure is a side view of the wooden structure of a drum-sawn log.

Cutting thicknesses 1 and 2 are the same thickness and are a quarter of the thickness 4 of the drum-sawn log. Thickness 3 is the -thickness of the part of thickness l.

The third figure is an actual series of Honki-gumi.

(Functions and Effects) Honkigumi enables mass production and uniform processing in factories, etc., and significantly improves both processing accuracy and speed.

In terms of strength, it was strengthened by 1 due to the shape that leaves most of the core part intact.

As for the machining shape, since the upper and lower parts are symmetrical, it is easy to convert the upper and lower parts or to replace the parts of the pond with wooden assemblies.

(Example: 5PfJ and f-mountain illustrations) Honki-gumi is a structure, furniture, and toys that are typified by log cabins and other structures.

It can be used for interior decoration, displays, etc.

As for processing tools, the uniform and straight processing of wooden logs made it easier to develop and manufacture automatic and power tools.
