Description

  The present invention relates to a solid wood composite panel that does not contain harmful substances and can be effectively used in, for example, residential construction, and a narrow board used for the solid wood composite panel.

Mountain forests act as dams. If the mountain gets rough, the water source cannot be maintained. In other words, if the forest is not managed manually, it will fall to fallen trees due to wind pressure and snowfall, and will not be preserved effectively. In particular, planted forests are not preserved effectively unless they take the effort of thinning, cutting undergrowth, and pruning (6-7 times a year). However, at present, there are many forests that are not managed manually because there is no labor cost even if the forest is cleared and removed. Therefore, in order to protect the mountain for the time being, the country uses a clear-cutting budget to cut trees. However, at present, this clear-cut and thinned wood is not used and is wasted.
On the other hand, in recent years, Japan's demand for timber depends on imported materials while destroying the global environment. According to the calculation by the Forestry Agency, the self-sufficiency rate of domestic timber is below 20% on average.
In Japan, too, resources are wasted due to clearing and thinning to preserve the forest because of the global environment.
Wood as a building circulation material cannot be used unless it has passed 30 years, 50 years, or 100 years, so it should be used carefully.
It is necessary to promote the use of domestic timber, to effectively use timber from forest resources in residential construction, and to maintain the global environment while balancing artificial and natural forests without wasting them. It has been.
Therefore, solid wood panels with free size, free shape and free cross section (synthetic single material) are not limited by thickness, shape and area, and can be assembled into solid wood panels and do not contain harmful substances such as formaldehyde. Development of a solid free size panel necessary for ecological construction that does not place a burden on the global environment, regional environment, and residents has been requested and has been proposed (for example, Patent Document 1).
[Patent Document 1] Special Table 2002-520198 gazette The above-mentioned solid free size panel can use local timber, reduce transportation costs, reduce CO2 emissions, has excellent heat insulation, humidity control, sound absorption, sound insulation effects, and can save energy. Environmental load can be reduced by manufacturing, transportation, disposal, and replacement of artificial materials.
Moreover, it is possible to provide a high-quality member with increased strength by suppressing the warpage of the board and processing the board material with a moisture content of about 15% after the dried and dried timber is processed into a square plate and dried in the field. It is preferable because standardization of parts and production control, quality control, and inventory control of buildings are possible.
Furthermore, it can provide added value of safety, health, healing and peace for people, and increase the value evaluation of buildings.
In other words, the wooden wall structure using this free-size panel can easily build an earthquake-resistant building, and can easily change the partition wall, ceiling, and second-floor part of the room. Can easily cope with changes in configuration and lifestyle.
Moreover, this free-size panel can be used for a frame structure, a wooden wall structure, a panel construction method, and a steel RC building, and has a great added value effect.
As described above, the prior art of Patent Document 1 is extremely preferable for the human environment and the global environment.
