Description

[Detailed Description of the Invention] The present invention is applicable to small-diameter wood such as Japanese cypress and cedar, for example, in the last days. ~/- A method of forming construction materials made from wood with a small diameter of the size of a saw. This article relates to a method for forming building materials other than those used to form the backbone of buildings, but it also relates to a method for forming building materials that can be applied to small objects with a thickness of approximately 100 x jOM or less, if necessary. be.

As is well known, small-diameter woods such as cypress and cedar (note, as mentioned above, the end of the range is about R~/Jffi) can be used for frames such as shoji, sliding doors, etc., and sliding doors such as bookcases for tableware (2). However, it was almost impossible to use anything with a thickness of 10Q x jQvur or more, which means that, for example, as shown in Figure 1, something with a tan (E) , If this is made into a square cross-section member (8) as shown in Fig. 1, the tortoise; is -
Side (81) is Jx! There is only a saw, and the cross section is a rectangular material (R) as shown in Figure S3.
-1) is only about OXt m, and since these dimensions are lumber dimensions, the effective dimensions are further reduced, and therefore it is difficult to be applied to the materials for sills, lintels, and edge decks as described above. Met. - Therefore, if this situation continues as it is, with limited natural resources and 1=
Although it will take many years, it is difficult to utilize the effective allocation.
In other words, it was a loss for the entire family.

The present invention has been made by focusing on the above-mentioned points, and its purpose is to use small-diameter wood, which has conventionally been limited in use, to be used as sills, lintels, etc.
The purpose is to provide a forming method that can be used for construction materials such as edge decks and other construction materials having a thickness of approximately θ0×jQwxm or more, and another purpose is to provide a construction material that eliminates distortion, warpage, twisting, etc., and that provides a good appearance. 1. Provides a molding method.

Next; Second, embodiments of the present invention that can achieve the above objects will be described in detail with reference to Figures 3 to //.

First, in the first step, a material (1
) on a rotary race (2) consisting of a pressure plate (2a) with a nose par (Jat) and a blade (Jl) 1) with a turret (2b) as shown in Figure Z, and remove defects such as holes and cracks. While removing veneer and preventing curls and rings, dry according to the conventional method! As shown in the picture, the thickness is 1) a throat, length/,), θan, width (brown!
Obtain a veneer (3) of about m. (Note: length 1> and width (
b) is converted into a desired value according to the purpose of use as lumber = Then, in the second stage, the wood surface (
With 3a) on the same side, the desired number of veneers (3) are arranged in parallel in the length direction (the direction of the quince) (see Fig. 4), and each veneer (3) is made by well-known technical means such as using thermoplastic resin tape in the width direction. By integrating, one board (3 people) of the desired length and width, so-called parallel joints, is obtained, but in some cases, as shown in Figure 1, /ρ large veneer (3 h) is obtained. ) may be used in combination.

Next, in the third step, using an even number of the seven boards (3mm) obtained as described above, glue the back side of the wood (3b) and the front side of the wood (3a) together as shown in Figure 9. Or, while gluing as shown in Fig. 10, the middle part is made perpendicular to the wood grain (
4) to obtain a polymeric material (P) of a desired thickness, and then add one stopper of s4 to the outer peripheral side of the polymeric material (P) as shown in Figure 1.
-For example, the top and left and right sides f! (The whole process is completed by pasting the veneer (5) once. Figure 7J shows an example of its use as a sill. In the same figure, grooves (4& ) The wooden, synthetic/resin, or metal sill component material (6) is fixed (for example, by gluing or screwing), but in some cases, the polymeric material (P) itself may be processed to form the sill. Sometimes it happens.

Since the present invention is based on the method described above, small-diameter wood such as cypress, cedar, etc. of 1~/2C, which had been conventionally limited in use, can be used for sills, lintels, edge decks, etc. with a thickness of 10θ×! The product obtained by the method of the present invention is a polymeric material in which a number of 7-ply wood backs and wood fronts are glued together. (-), the internal stress of the polymer material is dispersed, thereby eliminating distortion, warpage, twisting, etc.; This has the effect of eliminating the appearance of a polymeric material, that is, providing a good appearance.
