WOODEN PANEL MANUFACTURING METHOD AND WOODEN PANEL
To enhance wood preservation performance while maintaining dimensional stability.SOLUTION: A method for manufacturing a wooden panel of the present invention comprises: a first lumbering step of lumbering a base material from each of a plurality of pieces of first wood dried to a first moisture content; a second lumbering step of lumbering fastening wood from each of a plurality of pieces of second wood dried to a second moisture content lower than the first moisture content; a drilling step of arranging a plurality of pieces of lumbered base material in parallel with the longitudinal direction and drilling a plurality of holes penetrating the plurality of pieces of base material in the alignment direction; an assembling step of assembling the wooden panel by fastening the plurality of pieces of base material by press-fitting a plurality of pieces of lumbered fastening wood one by one into at least two of the plurality of holes; a pressurized injection step in which a wood preservation solution, consisting of the wood preservation agent dissolved in an organic solvent, is pressurized and injected into the assembled wood panels; and a solvent discharge step for vaporizing or liquefying at least the organic solvent from the wooden panel and discharging the vaporized or liquefied organic solvent.SELECTED DRAWING: Figure 1
【課題】寸法安定性を有しつつ、木材保存性能を高めること。【解決手段】木製パネルの製造方法は、第１の含水率まで乾燥させた複数本の第１の木材のそれぞれから基材を製材する第１の製材工程と、第１の含水率より低い第２の含水率まで乾燥させた複数本の第２の木材のそれぞれから締結木材を製材する第２の製材工程と、製材された複数の基材について長手方向に対して並行に配列し、当該複数の基材を配列方向に貫通する複数の穴を穿孔する穿孔工程と、複数の穴のうち少なくとも２つ以上の穴のそれぞれに、製材された複数の締結木材を１本ずつ圧入することにより、複数の基材を締結して木製パネルを組み立てる組立工程と、木材保存用薬剤を有機溶媒に溶解した木材保存溶液を、組み立てられた木製パネルに加圧注入する加圧注入工程と、木製パネルから有機溶媒を少なくとも気化又は液化させ、気化又は液化された有機溶媒を排出する溶媒排出工程と、を備える。【選択図】図１
