JP2003291114A - Hollow arrayed pillar wall of woody rectangular pillar or the like with air layer - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that a natural solid wood needs to be chemically treated using a resin or by acetylation in order to deal with a hygroscopic action and unless this treatment is performed, cracking, warpage, contraction and the like occur due to a change in the moisture content of the wood, and that many working and treatment steps for holding for wiring and embossing of the conventional processing method need to be simplified. <P>SOLUTION: The cracking, warpage, contraction and the like of the natural solid wood as qualitative defects are prevented from occurring to the maximum possible extent with the adoption of drying technique and assembling technique such a cutting or bonding of the woody material. In addition, the role of the hollow arrayed pillar wall adopting the air layer introduced into the assembled pillar to be played in a residential architecture, is diversified and the effect of the role is considered significant. Further, since a residence adopting the hollow arrayed pillar wall necessarily uses a larger quantity of woods, compared with the residence built using a conventional technique, the indoor living environments are upgraded with the addition of acoustic/ sound insulating properties, heat insulating properties and moisture-conditioning performance. Besides, the building period using said pillar wall can be widely cut, compared with the conventional building period. <P>COPYRIGHT: (C)2004,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow laminated column and a hollow column wall formed using the laminated column, in which cracks, warpage, shrinkage, and the like are prevented as much as possible by using a drying technique and a laminated processing technique. 2. Description of the Related Art A column pillar wall structure based on a conventional utility model registration No. 3076292 is manufactured using a solid single tree of cedar and cypress, so that cracks and warpage, which are the characteristics of wood, are obtained. Frequently occurring, the aesthetic value of the product is impaired, and the water content of the timber is high, and the high shrinkage of the tree is also an issue.
Also, the need for unevenness processing of a single tree, which is a part of the column wall structure, is low, which increases the cost of the product and requires simplification of the processing. Furthermore, electrical wiring is required for the columnar wall structure, and when this is to be performed, processing for newly forming wiring has been a problem. [0003] However, solid wood, which is a natural material, must be treated with a chemical treatment such as resinification or acetylation to prevent moisture absorption. As long as it is used, cracks, warpage, shrinkage, etc. occur due to changes in the moisture in the wood.
Further, in the conventional processing methods, there are many work and processing steps such as a wiring drilling process and a concave-convex process, and it is necessary to simplify the process (problem). DISCLOSURE OF THE INVENTION The present invention is to prevent short-term drying, because cracks, warpage, shrinkage, etc., which are the characteristics of wood, are prevented as much as possible by a natural method without using chemical treatment. The drying of the wood was simplified by cutting the annual rings except for the core of the wood into thick plates. Artificial drying is performed in a drying oven in the state of a thick plate to reduce the moisture content in the thick plate, that is, the water content to 10% or less, and to assemble two thick plates that minimize cracks, warpage, shrinkage, etc. Making a glued pillar by making full use of
Aggregation improves the shortcomings of wood and therefore outperforms solid wood in strength. One side of the dried thick plate is subjected to scooping in the shape of a U-shape and the like in FIG. 3 vertically, and the scooping surfaces of the U-shape and the like are combined, and two thick plates are press-bonded by an assembly processing technique. The shape figure of FIG. 4 which makes one pillar, such as a composite rectangle which has a rectangular air layer. Based on six rectangular columns or the like having an air layer, they are arranged vertically and fixed in a plate shape to form a wall body. DESCRIPTION OF THE PREFERRED EMBODIMENTS Cracks and warpage caused by shrinkage of wood occur because moisture in the wood evaporates from the wood due to drying of air. This is the direction of the tree rings
It occurs because the amount of shrinkage (difference) of the radial door from the vertical ring differs from the annual ring. The difference in shrinkage due to the difference between the annulus direction and the radial direction is called illegal shrinkage. Generally, it is said that the contraction amount in the annual ring direction is about twice as high as the contraction amount in the radial direction. Therefore, as the drying proceeds, the difference (difference) in the amount of shrinkage increases, and as a result, cracks and warpage occur. To prevent this, the problem can be solved considerably by minimizing or eliminating the cause in the relationship between the annual ring direction and the radial direction in the wood. In the present invention, the cause which is likely to occur due to the solid state in which the defect is left and which occurs in the relationship between the annual ring direction and the radial direction can be suppressed extremely low by hollowing the solid material. further,
By assembling in the direction opposite to the direction of the annual rings, it is possible to correct the direction of change such as shrinkage or warpage that occurs in a certain direction during drying of each member. By performing processing combining these two techniques, the above-described problems that occur when using wood as solid wood can be significantly solved. FIG. 3 is a shape diagram of FIG. 2 which is formed as a laminated pillar using two thick plates in the shape diagram shown in FIG. 1. Further, by integrating two thick plates and providing an air layer, the heat insulating effect is increased, and a construction method and structure excellent in both sound absorbing and insulating properties and heat insulating properties can be expected. Then, when the wood is processed by the gluing processing technology, by crimping the back of the wood and the back of the wood back to back, the effect of preventing warping of the wood and cracking of the wood is also produced.
In processing, solid wood is dried and then cut and glued to form an aggregate, which is very effective in preventing the expansion and contraction of wood. According to the present invention, The use of hollow column walls with an air layer in the laminated columns requires more wood in the room than in the conventional construction method housing, so sound absorption and insulation, heat insulation, humidity control performance is added, and the indoor living environment is improved. Further improvement can be expected. 2. Since the air layers are provided vertically on the laminated columns, the use of the holes in the air layers simplifies electrical wiring work and the like.
In addition, it is possible to enhance the function of the house by using the air layer of the assembled columns and adopting the air cycle method. 3. By utilizing the artificial drying technology and the laminating processing technology and providing an air layer on the laminating column, cracks, warpage, shrinkage, etc. of the tree are minimized.
