Manufacture process of factory prefabricated steel concrete composite pipe

Abstract

The invention discloses a factory prefabricated steel concrete combination pipe making technology. The technology comprises following steps: firstly, according to the construction drawing need, the number and the related sizes of steel concrete combination pipes with multiple cross sections of the rectangular structures are designed; secondly, according to the drawing need, the steel concrete combination pipes are prefabricated in the factory in a segmented manner; thirdly, the steel concrete combination pipes are connected to form straight-line-shaped, the leftwards-rotated-T-shaped, an inverted-L-shaped, crossed or mouth-shaped structures. Inner concrete, outer concrete and reinforcing meshes are combined with a steel plate with the inner side with ribs to form a whole steel concrete combination shear wall through binding bars, joint work is achieved, ductility and compressive strength of the concrete are greatly improved, plasticity and toughness of the whole steel concrete combinedshear wall structure are greatly improved, the anti-deforming capacity and the anti-pressing strength of the shear wall are greatly improved, and meanwhile, due to the fact that the steel plate withthe ribs is wrapped by the concrete, the fireproof anti-corrosion aims of the steel structure building can be effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a manufacturing process 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 s...
