Composite material based building material structure

Abstract

A composite material based building material structure includes a metal member and a combination member. The metal member includes a connection plate and two lateral plates disposed on two ends of the connection plate. The two lateral plates extend toward an identical side of the connection plate, forming a combination groove. The metal member includes a plurality of first connection portions on an outer periphery of each lateral plate. The combination member is formed of wood plastic composites, and has a recess for receiving the metal member. The combination member includes a plurality of second connection portions on an inner periphery of the recess, for correspondingly receiving the first connection portions, such that the combination member is mounted on an outer side of the metal member. Thus, the metal member is prevented from moisture, achieving increased life span of the building material structure.
