Abstract

An end reinforcing type steel-concrete composite pipe comprises an up-down through rectangular cylindrical structure which is defined by inner side steel plates, outer side steel plates, left reinforcing profile steel and right reinforcing profile steel. A plurality of tie bars are arranged between the inner side steel plates and the outer side steel plates, the inner ends and the outer ends of the tie bars extend out of the inner side steel plates and the outer side steel plates towards the two sides correspondingly, a steel bar skeleton with the cross section being of a rectangular structureis 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, 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 end reinforcing type steel-concrete composite pipe, the 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, the anti-deformation ability and compressive strength of a shear wall are greatly improved, and the fireproof and anticorrosion problems are also solved effectively.

Description

technical field

[0001] The invention belongs to the technical field of structural engineering, and in particular relates to an end-reinforced 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. Contents of t...
