Analysis on Exterior Wall Conformation of Low-Rise Light Steel Structure Residence Based on Thermal Theory

Abstract

Light steel structure residence is an optimum selection for the realization of building energy-saving and meeting of green building evaluation standards. Two kinds of system of light steel structure are analyzed and construction method for lightweight combination wall and infilled outer walls of low-rise light steel are summed up. Analysis on exterior wall conformation in low-rise light steel structure is put forward. Results indicate that special construct of light steel structure is equivalent to set closed air space, and thermal performance of infilled external wall of light steel structure is superior to that of traditional structure. And thermal performance of using aerated concrete wall panels as filled outer wall of light steel structure is better than that of aerated concrete blocks and thermal stability of filled external wall of light steel structure is better than lightweight combination external wall. The conclusions provide a theoretical foundation for building energy-saving in light steel structure residence and optimal design of residential environment.
