Abstract

The invention provides a detachable prefabricated modular shear wall based on profile steel connection, and an assembly method thereof. The detachable prefabricated modular shear wall comprises a reinforced concrete wall, an upper steel connecting part, a lower steel connecting part and a middle reinforcing connecting part, wherein first screw holes are formed in the tops of I-shaped steel platesat the two ends of the upper steel connecting part, second screw holes are formed in web plates of the I-shaped steel plates at the two ends of the upper steel connecting part, and first bolts are pre-mounted in the first screw holes; third screw holes are formed in the bottoms of steel foot seat plates at the two ends of the lower steel connecting part, and fourth screw holes are formed in I-shaped steel web plates at the edge of the lower steel connecting part; middle screw holes are formed in web plates of I-shaped steel plates at the two ends of the middle reinforcing connecting part; andthe detachable prefabricated modular shear wall further comprises strip-shaped steel plates, steel bars and concentric-square-shaped steel rings. The invention further provides the assembly method. The strength realized by the detachable prefabricated modular shear wall is equal to the strength of a cast-in-place prefabricated shear wall, and the detachable prefabricated modular shear wall more meets the strong joint design requirements in function compared with a wet connection structure; and the mode that profile steel serves as prefabricated components for connection is adopted, and compared with traditional wet connection, the advantages that positioning is more accurate, installation is faster, the quality is easier to check, and the construction cost is saved are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a detachable prefabricated modular shear wall based on section steel connection and an assembly method thereof. Background technique [0002] Prefabricated shear walls are widely used all over the world, and prefabricated shear walls can realize the industrialized production of buildings. In the case of declining demographic dividend and high cost of on-site construction personnel, the development of prefabricated structures may be a new direction of building construction. At the same time, the prefabricated structure is energy-saving and environmentally friendly, and can greatly reduce the adverse effects of on-site construction. Under high environmental protection requirements, the cast-in-place operation on the construction site will be impacted. The use of fully prefabricated structures can well overcome on-site noise, dust and other pollution. At the same time...
