At this stage, construction cost is the main factor restricting the development of construction industrialization. The cost of the main structure of the prefabricated house is mainly composed of the cost of wall panels, beams, and column components, of which the cost ratio of exterior wall panels is the highest. Traditional low-rise buildings are mainly brick-concrete structures, reinforced concrete frame structures, and light steel keel structures. Among them, the brick-concrete structure has many shortcomings such as poor seismic performance and poor energy-saving performance, and is used less and less. The mechanical properties of reinforced concrete frame structure are better, but it is not conducive to prefabricated construction. Light steel keel structure houses are currently the most commonly used low-rise prefabricated houses, but because their manufacturing costs are much higher than traditional low-rise house structures, their popularization and application are affected.
