The ligneous junction board for the structural material junction in the wooden building and component null for structure

摘要

PURPOSE: To improve the execution properties, strength and resistance to fire of a woody cmenting plate and prevent the generation of condensation by impregnating a thin wood veneer with synthetic resin liquid, carrying out moisture conditioning properly, and then applying a bonding agent, making the fiber direction of veneer parallel or partly crossing and laminating. ;CONSTITUTION: A wood veneer such as rotary veneer or slice veer is impregnated with synthetic resin liquid of condensation type, addition polymerization type or water solution type, and the water content is moisture conditioned to 20-30%. The fiber direction of the veneer is made parallel or partly crossing and laminated by using a bonding agent. Then, a laminate is heat compressed to the proper thickness by a hot plate press. A cemented plate is formed by using a reinforced veneer laminating material thus manufactured, and a woody cemented plate 7 thus manufactured is fixed by a bolt 8 from the side face of, for instance, a joint 5 or a connection of a pillar or a beam 4. Also the strength can be improved by inserting a thin metal sheet of aluminum or the like or a fibrous reinforcing material or the like among the veneers impregnated with resin.;COPYRIGHT: (C)1994,JPO&Japio
