With the continuous improvement of the mechanization degree of the construction industry, the construction industry is a necessary trend for the development of the construction industry in the future. At present, an important implementation approach for building industrialization is to develop a fabricated building. The prefabricated steel structure and the prefabricated concrete structure in the existing prefabricated building structure develop rapidly, but the prefabricated steel and concrete combined structure develops slowly. Due to the lack of research on an assembly type steel and concrete combined structure system, the development of the steel and concrete combined structure with the advantages of earthquake resistance and fire resistance is limited. Therefore, the improvement of the novel efficient assembly type combined structure system is the premise of vigorously promoting the application of the assembly type steel and concrete combined structure in the building, and is an important way for promoting the development of the assembly type building and realizing green and low-carbon construction.
In traditional steel-concrete integrated configuration, the independent foundation often adopts cast-in-place construction mode, and the work progress is complicated loaded down with trivial details, and the basis needs formwork, ligature reinforcing bar, concreting at the job site, just can install superstructure after maintenance concrete reaches design strength, and this independent foundation under just leading to cast-in-place reinforced concrete column has many shortcomings: 1) the construction period is long, which is not beneficial to realizing building industrialization; 2) the construction process is easy to cause environmental pollution, and is contrary to the concept of green construction; 3) the quality of the cast-in-place concrete is difficult to control, so that the foundation quality is difficult to ensure. The cup opening is a groove with a large upper part and a small lower part, and is generally used in industrial plants, and the problem of difficult positioning exists when the column is assembled with the cup opening foundation.
