Composite membrane of wood floor diaphragm

Abstract

A composite membrane of wood floor diaphragm for construction of new buildings and strengthening of existing buildings to provide improved load transfer capacity and enhanced resistance to gravity and lateral loads, such as earthquake and/or wind for buildings with wood floor framing. The composite membrane extends beneath the wall framing to utilize the composite membrane diaphragm as a load and shear bearing element.

1 . A composite membrane of structural wood floor diaphragm for a building having exterior wall framing, comprising:
 a plywood subfloor comprising a plurality of plywood panels;   a parquet floor directly attached via adhesive to the plywood subfloor, the parquet floor oriented diagonally with respect to edges of the plywood panels and comprising four-way interlocking units; and   shear transfer connectors installed through the composite membrane of wood floor diaphragm;   wherein the parquet floor extends underneath the wall framing.
