STRUCTURAL PLYWOOD IN BUILDING

摘要

PROBLEM TO BE SOLVED: To increase the shearing strength of a nail to be driven into a structural plywood frame made of architectural members. ;SOLUTION: Iron plates 5 are laminated with a plurality of wooden boards 4 and bonded together to constitute structural plywood 1. The shearing strength of a nail to be driven into a structural plywood frame 2 made of architectural members can be obtained by the interposition of the iron plates and the fixing strength of the structural plywood 1 against the frame 2 is sufficiently obtained. And hence, the allowable strength as structural plywood 1 can be greatly increased.;COPYRIGHT: (C)1997,JPO
