Fabricated composite wall based on steel pipes and construction method thereof

The invention discloses a fabricated composite wall based on steel pipes and a construction method thereof. The fabricated composite wall comprises a prefabricated wallboard which is arranged on a foundation beam, the prefabricated wallboard comprises a steel pipe composite wall framework, building blocks and a concrete outer cladding layer, the steel pipe composite wall framework is of a rib lattice structure formed by splicing a plurality of steel pipes, and the rib lattice structure is filled with building blocks; wall connecting pieces are evenly arranged at the bottom end of the prefabricated wallboard and arranged at the joints of rib columns and rib beams of the prefabricated wallboard; and a foundation embedded part is embedded in the top end of the foundation beam, and the wall connecting part is connected with the foundation embedded part through a high-strength bolt. According to the fabricated composite wall, through the synergistic effect of the steel pipe composite wall framework and the concret
