Description

[Detailed description of the invention] The present invention (d) relates to a method for manufacturing wooden blocks.

Nowadays, decorative plywood is exclusively used for wall materials and fittings, but these decorative plywoods lack a sense of solidity because they are relatively thin.

On the other hand, sawn timber (square or board) that is cut in the traditional straight-grained or heathered pattern for the sake of authenticity inevitably warps and cracks during drying and after construction, making it unsightly. In order to arrange the pattern pattern 1〉 with a constant pattern and heather, it requires a lot of wood and is expensive.The present invention aims to solve the problems mentioned above in Hereinafter, an example of the implementation of the present invention will be explained based on the accompanying drawings.

In Figure 7, 1 has a diameter of approximately 86 mm to 3 cm.
It is about 16 trees. Raw wood of such dimensions can be obtained in large quantities and at low cost, either as thinned wood of cypress or cedar, or as 11-thick wood.

In the present invention, log 1 is cut in the range of α-10' to 70° and into t-=10 IrJ-'ROO-I7. View,

In contrast, 3C13d is a groove.

FIG. 3 is a plan view of a state in which the wooden Glock 3 formed as described above is continued as a wall plate. For this series, a thin plywood board can be used for the 5th lower plate and L2, but if there is already a Y-shaped base layer, it should be attached directly to the L side using a berthing agent etc. I can't even get a meter. In addition, in the figure [■j, 4 is the wooden block 3 -・
The groove is formed in the center of the L1 side, and the above-mentioned pasting work can be done easily and the surface of the torsion can be made uniform. be.

In the present invention, cutting the raw wood] within the range of α-10° to 70° means that when α is 9° or less, there is not much difference from the conventional sawn into a plate shape, resulting in distortion of the product. Moreover, if α exceeds 700, numerous core cracks will suddenly occur inside the block, which is undesirable.

In the present invention, in the center of the cut 1 [+ + mouth II (d), a turning-shaped growth ring S is necessarily exposed along with the pattern, and the spread of the pattern is related to the above cutting angle α. In other words, when a is small, V' is large, whereas when a is large, it is small. The cutting angle α is related to the size of the block to be formed, that is, the J-1 dimension, so the necessary angle is determined by adding the steel weight to the length of the Glock you are trying to obtain. Become.

j=-1) V-view 11-2 In order to give the block 3 a three-dimensional effect, it is necessary to keep the thickness within a certain range. There is an embankment, and in the present invention, 7

However, when 0 exceeds '70', the above-mentioned striped pattern spacing becomes too dense, resulting in the above-mentioned three-dimensional effect.On the other hand, when 0 is less than 15 degrees, the overall angle is 4.
11, the effect is similarly weakened, and this particularly preferred angle is 1=
From 15 Noah to 20 + Qing, θ=30° and 60°.

The present invention is constructed as follows, and conventional square timbers and board materials inevitably crack when drying and after construction, making it difficult to select materials, and even using straight-grained timbers or full-grained timbers. In contrast to the previous invention, which required many zangetsu to form a certain stable pattern, it is possible to make a certain spiral pattern appear under the same conditions by using a small diameter, thinned wood, etc. It is more beautiful than the conventional plain A-o, and causes almost no distortion or cracking.

This small path () and thinned wood can be produced very cheaply.
Because of this, the product itself can be manufactured at a low cost, and the product, which has a ton-sleeved and three-dimensional feel, can be used for a wide range of purposes such as wall materials, construction materials, and metal fittings.

It should be noted that conventional square timbers had a back saw to prevent cracks in the middle, but such work is not necessary for blocks manufactured by the uninvented method.

Claims (2)

[Claims] (1) The angle at which logs with a diameter of approximately s cm to H5 cm are cut;
and a = 10°, 700-7', and J'r'sl
== 10 rflM, 3011111 In addition to making one cut and cutting the outer periphery into a square, it is necessary to make a 7113-minute cut in the center of the 11-night sloping wall surface with the solid side 6 being approximately 15° to 7o0. This method of manufacturing a wooden Glock is characterized in that the wooden Glock is manufactured in such a manner that the annual ring pattern is uniform. (2) A method for producing a wooden block as described in Paragraph 1 of the scope of patent 1, characterized in that the wood is cypress or cedar.
