Prismatic wood compression molding method and compression molding device therefor |
摘要 |
A prismatic wood compression molding method capable of easily producing long-sized lumber usable as pillars or like by compression molding. The method is characterized by comparing the steps of: using a plurality of rigid plate-like bodies such as metal plates to compress an outer face of wood throughout length thereof to compression-mold it into prismatic wood which is polygonal, such as rectangular or hexagonal, in cross section; restraining the plate-like bodies by a restrain jig so as to hold flat surfaces of the prismatic wood in a state in which they are compressed by the plate-like bodies; and applying a heat treatment to the prismatic wood held in the compressed state by the plate-like bodies and the jig so as to permanently fix the shape of the prismatic wood.
