Abstract

A factory prefabricated steel-concrete composite pipe comprises a rectangular cylindrical structure made of steel plates and / profile steel. Tie bars are arranged between the inner side face and the outer side face of the rectangular cylindrical structure, the inner ends and the outer ends of the tie bars extend out of the rectangular cylindrical structure towards the two sides correspondingly, anda steel bar skeleton is arranged on the periphery of the outer portion of the rectangular cylindrical structure; gaps are formed between the steel bar skeleton and the rectangular cylindrical structure, the inner side face and the outer side face of the steel bar skeleton are fixedly connected to the inner ends and the outer ends of the tie bars correspondingly, and the left side face and the right side face of the steel bar skeleton are fixedly connected with the rectangular cylindrical structure through studs correspondingly; and concrete is poured on the periphery of the outer portion of the rectangular cylindrical structure, and thus the steel bar skeleton is coagulated. According to the factory prefabricated steel-concrete composite pipe, the building construction efficiency is improved, the ductility and compressive strength of the concrete are greatly improved, the plasticity and toughness performance of a whole steel-concrete composite shear wall structure is greatly improved,and the fireproof and anticorrosion problems of steel structure buildings are also solved effectively.

Description

technical field

[0001] The invention belongs to the technical field of structural engineering, and in particular relates to a factory prefabricated steel-concrete composite pipe. Background technique

[0002] The components of the prefabricated building can be industrialized in the factory. The components are equivalent to standard products, and they can be installed directly on site. field, has its incomparable superiority; components are produced standardizedly in the factory, the quality is more guaranteed than on-site production, and can be effectively controlled. The high-standard mechanization of components reduces the number of on-site personnel. Both labor cost and safety production are helpful.

[0003] The components of existing prefabricated buildings have the following technical problems: 1. Poor fire protection performance; 2. Poor corrosion resistance; 3. Complicated procedures during on-site construction and slow construction progress; 4. High cost. Content...
