Background technique

At present, due to the shortage of labor force and the increasing emphasis on environmental protection, my country's construction industry is in the process of transformation and upgrading. In order to implement the basic national policy of "energy saving, consumption reduction, emission reduction, and environmental protection", many domestic construction companies are actively adapting to the new normal, learning new knowledge, and striving to make due contributions in the field of prefabricated buildings in my country. However, the further popularization and application of prefabricated concrete structures is also facing bottlenecks, mainly manifested in the fact that the main components of prefabricated concrete structures are prefabricated in factories and transported to the construction site for installation. The requirements are higher, but the overall professional quality of the current construction personnel is not high, the lack of accumulation and summary of technical experience in prefabricated concrete structures, and the lack of comprehensive and detailed understanding and mastery of the process flow and operating points of prefabricated structures, resulting in low construction efficiency , The construction error is too large, and even construction errors occur.

The superimposed structure is a new type of overall statically indeterminate structure that is made of prestressed concrete superimposed components in the component factory, and then superimposed with cast-in-place concrete after installation on the project site. The side formwork support method of the conventional composite beam-slab structure is the same as that of the conventional cast-in-place structure. The side formwork is fixed by drilling holes and cross-tensioning bolts or nails. Bolts, and directly perforating and nailing the wooden formwork will reduce the number of recycling of the formwork, and cannot reflect the advantages of the prefabricated structure.
