Description

Technical Field

[0001] The invention relates to an assembled concrete frame building, in particular to an assembled prefabricated wall panel and a prefabricated beam. Background Art

[0002] As we all know, the prefabrication of buildings has the advantages of improving project quality, shortening construction period, simplifying on-site construction process, reducing construction intensity, improving site environment, reducing pollution, and reducing wet operations. At the same time, prefabricated and assembled buildings can effectively save resources and energy, help to give full play to the performance of materials in achieving building energy conservation and structural stress, and reduce the demand for site and environmental conditions for on-site construction. Prefabricated assembled frame shear wall structure is one of the very important structural forms. In current projects, it is mainly reinforced concrete beam-column frame structure, and then the shear wall is cast in place. This type of shear wall fails to adopt prefabricated structure, and it is also necessary to tie steel bars, erect formwork, and pour concrete. The construction is complicated and the construction period is long. For multi-story structures, steel tube concrete has been increasingly used due to its good stress performance. However, if it is used in an assembled frame shear wall structure, its connection with the shear wall is an important link. How to connect the shear wall with the beam and column is also a concern of everyone. At present, sleeve grouting connection is used. This connection method is single and the construction quality is difficult to guarantee. The steel bars at the connection are spaced and connected, the connection is unreliable, and there is no thermal bridge between the insulation layer and the shear wall. Summary of the invention

[0003] The purpose of the present invention is to provide an assembled prefabricated wall panel and prefabricated beam, which has a high degree of assembly and can eliminate thermal bridges in the wall panel, while ensuring the rigidity of the concrete shear wall and realizing convenience for mass production and on-site assembly.
