Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of cutting wooden structural materials used for beams, pillars, walls, etc. of wooden structures from natural wood, instead of using various wood members processed to design dimensions with an adhesive. The present invention relates to a wooden synthetic structural material artificially manufactured by combining and bonding.

[0002]

2. Description of the Related Art Conventionally, wooden materials used for building a wooden building such as a wooden house can be roughly classified into structural materials and decorative materials. In recent years, due to the depletion of timber resources and the rise of global environmental conservation movements, wooden buildings have become expensive and luxurious buildings. For this reason, research on industrialized woody materials for collecting and using relatively small pieces of wood to produce and use large woody materials for effective use of wood has been active. The industrialized wood material is, for example, a structural glued laminated material or a single-layer laminated material shown in FIGS. Until now, this industrialized woody material has often been used as a small raw material or as a decorative material, and its use as a structural material for building a wooden building has been low. The reason is that due to the inadequate development of adhesives and bonding technology, it was not possible to have sufficient reliability in the bonding strength and durability. Only small and small materials had practical value. At the same time, due to the abundance of natural timber, large, heavy-duty wooden structural materials were easily available at a reasonable cost, eliminating the need to use artificially made timber alternatives. It is because.

[0003] In recent years, as the timber for construction has become a valuable item, in particular, as it becomes more difficult to obtain a wooden structural material having a large size, durability and good appearance, the industrialized wood material is used for structural purposes. It has been used as a structural material for beams and columns. However, when using the industrialized wood material as a structural material, it is only used as a substitute for wood, so special joint metal fittings like natural wood structural materials cut out from natural wood and formed, The processing of complicated joints is performed, which causes waste of materials, labor and time due to joints and joint processing. In addition, the structural material made of industrialized woody material has the same weight or more than the wooden structural material, and is difficult to handle. Furthermore, structural materials made of industrial wood materials require the use of a large number of bolts in order to increase the frictional force between the special hardware and the connecting surface of the material, but serious defects such as cracking of the tree due to tightening of the bolts. Was likely to occur.

[0004]

SUMMARY OF THE INVENTION The present inventor has conducted various studies to solve the above-mentioned problems, and as a result, it has been requested to develop a new industrial wood material as follows. Think.

First, in recent years, not only large natural trees, which can be used as beams and pillars of wooden structures by simply cutting and processing wood, have been depleted, but even if they are extremely expensive and economically expensive. It is becoming unavailable.
For this reason, industrialized wood materials such as structural glued laminated lumber and single-layer laminated materials tend to be increasingly used in the future for structural materials.

Second, in recent years, an adhesive for woodworking which is easy to use and has a strong adhesive strength has been developed, and the strength and durability of the bonded synthetic wood have become reliable. It has become easier to manufacture industrial wood materials such as lumber.

Third, traditional wooden buildings made of natural wood are widely regarded as being expensive, and the fragrance, texture, and appearance of the trees are becoming more admirable. Nowadays, even industrialized wood materials can be convinced. Fourth, the inventor has developed a useful new artificial wood material having a function higher than that of natural wood, rather than a substitute for natural wood, as in the case of conventional industrial wood materials. It is desired to embody a wood-based synthetic structural material that can evolve more.

That is, the invention of the present application is to reduce the weight while maintaining the characteristics of the wood and to reduce the weight by forming an open or closed hollow inside the structural material using the industrialized wood. Having the same strength as the structural material, forming a hollow part inside the structural material, creating an air layer here, or embedding appropriate materials such as foamed resin, zeolite and soundproofing material in this hollow part By improving the functions such as humidity control, soundproofing, and heat insulation from natural wood, and by forming connections and joints from the beginning when designing and bonding,
