Description

Solid wood composite panel and narrow board used for this panel

Technical field

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

Akira Background technology

Mountain forests act as dams. Therefore, if the Mt. In other words, unless forests are managed manually, wind pressure and snow will cause them to fall, which will not be preserved effectively. In particular, planted forests cannot be effectively preserved without thinning, weeding and pruning (6-7 times a year). However, in the present situation, many forests are not managed by human labor, because even if the forests are cleared and excavated, there is no labor cost. There, the government has allocated a budget for clear cutting to cut the trees to protect the mountains for the time being. However, at present, these clear and thinned woods are wasted without being used.

On the other hand, in recent years, Japan's timber demand has relied on imported timber while ruining the global environment. According to the Forestry Agency, the self-sufficiency rate of domestic timber is below 20% on average. In Japan, too, clear cutting and thinning are being performed to protect the forest and protect the forest, and resources are being wasted.

Timber as a building material cannot be used until 30, 50, and 100 years have passed, so it must be used with great care.

Promoting domestic timber, making effective use of wood from forest resources for housing construction without wasting it, and maintaining the global environment while maintaining a balance between planted and natural forests It has been demanded.

Therefore, solid wood panels of free size, free shape and free cross section (synthetic single material) can be assembled with no restrictions on thickness, shape and area. In addition, there is a need for the development of solid free-size panels that are free of harmful substances such as formaldehyde and are required for ecological construction that does not impose a burden on the global environment, local environment, and residents. Patent Document 1).

[Patent Document 1] Japanese Patent Application Publication No. 2000-502

The above solid free-sized panels can use local wood, reduce transportation costs, reduce CO2 emissions, have excellent heat insulation, humidity control, sound absorption, and sound insulation effects, and can save energy, and can be manufactured, transported, disposed of, and made of artificial materials. Environmental load can be reduced by such means as replacement.

In addition, the dried and dried wood can be sawn into a plate shape, and after laminating and drying, processing a plate material with a moisture content of about 15% can suppress warping of the plate and provide high-quality members with increased strength. It is preferable because standardization of components and production control, quality control and inventory control of buildings are possible.

In addition, it can provide added value to people for safety, health, healing, and ease, and increase the value of buildings.

In other words, the wooden wall-type structure using this free-size panel can easily build an earthquake-resistant building, and can easily change the partition walls, ceiling, and second-floor floorboard that make up the room, Can easily respond to changes in family structure and lifestyle. This free size panel can also be used for framed structures, wood-walled structures, panel construction methods, and steel-framed RC buildings, resulting in a large added value effect.

As described above, the prior example of Patent Document 1 is extremely preferable for a human environment and a global environment.

That is, on the upper surface of the narrow plate 21 for the internal structure, a concave portion 23 and a convex portion 2.4 that are alternately continuous in the longitudinal direction are formed to the full width of the narrow plate. Since the concave and convex portions 2 3 and 24 are continuous in the longitudinal direction of the narrow plate 21, a set of the concave portion 23 and the convex portion 24 is similarly formed. A locking recess 27 is formed in the lower portion of one side wall 25 opposite to the boundary wall 26 between the recesses 23 and the projections 24 of 3, 24.

Next, the lower surface of the narrow plate 21 for the internal structure has exactly the same configuration as the back surface serving as the lower surface of the second surface narrow plate 11, and the concave portion 3 3 and the convex portion in the direction along the longitudinal direction of the narrow plate 21. 3 4 is provided, a locking groove 36 along the longitudinal direction of the narrow plate is formed below the side wall 35 on the side of the convex portion 34, and a locking ridge 3 7 along the longitudinal direction is formed on the lower edge thereof.
