Embodiment 1

[0030] Example one: such as figure 1 with image 3 As shown, the manufacturing method of the factory prefabricated steel concrete composite pipe of the present invention includes the following steps:

[0031] (1) According to the requirements of the construction drawings, design the number and relevant dimensions of several sections of steel-concrete composite pipes with rectangular cross-sections;

[0032] (2) The steel-concrete composite pipe is prefabricated in sections in the factory according to the requirements of the drawings; the steel-concrete composite pipe includes a bent rectangular cylindrical structure steel plate 1. The two long sides of the steel-concrete composite pipe in a rectangular structure are respectively The inner and outer sides of the rectangular tubular structural steel plate 1, and the two short sides of the steel-concrete composite pipe in a rectangular structure are the left and right sides of the rectangular tubular structural steel plate 1, respecti...

Embodiment 2

[0049] Embodiment two: such as figure 2 As shown, the difference between this embodiment and the first embodiment is that the rectangular cylindrical structural steel plate 1 is formed by bending and welding a profiled steel plate. The cross-section of the profiled steel plate is triangular, trapezoidal, arc, wavy or folded Linear.

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 specifically relates to a method for manufacturing a factory prefabricated steel-concrete combined 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. It can be said that it is convenient and fast, and it is a building that is competing for more than a second time. The field has its incomparable advantages; the components are standardized in the factory, and the quality is more assured than on-site production, and can be effectively controlled. The high-standard mechanization of the components reduces the number of on-site personnel. Both labor costs and safety production are helpful. [0003] The existing prefabricated steel-concrete composite pipes manufactured in the factory have the following technical problems: 1. Poor...
