Manufacturing method of factory prefabricated steel concrete composite pipe

Abstract

A manufacturing method of factory prefabricated steel-concrete combined pipes comprises the following steps that (1) the number and relevant sizes of multiple steel-concrete combined pipes with crosssections of rectangular structures are designed according to the requirements of a construction drawing; (2) the steel-concrete combined pipes are prefabricated in a factory in a segmented manner according to the drawing requirements; and (3) after the steel-concrete combined pipes are connected, I-shaped structures or T-shaped structures or L-shaped structures or cross-shaped structures or squarestructures are formed. In the manufacturing method, inner concrete, outer concrete, steel bar net pieces and steel plates with ribs on the inner sides form an overall steel-concrete combined shear wall through tie bars to work together, and therefore the ductility and compressive strength of the concrete are greatly improved, the practicality and toughness properties of the structure of the overall steel-concrete combined shear wall are greatly improved, and the anti-deformation capacity and compressive strength of the shear wall are greatly improved; and meanwhile, due to the fact that the steel plates with the ribs are wrapped in the concrete, the problems of fire prevention and corrosion prevention of a steel structure building are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a manufacturing method of 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 steel-concrete composite pipes produced in the factory for existing prefabricated buildings have the following technical problems: 1. Poor fire performance; 2. Poor corrosion resistance; 3. Poor durability of the assembled shear wall st...
