Embodiment 1

[0026] Embodiment one: if figure 1 and image 3 As shown, the manufacturing method of the factory prefabricated steel-concrete composite pipe of the present invention comprises the following steps:

[0027] (1) According to the requirements of the construction drawings, the number and related dimensions of several sections of steel-concrete composite pipes with a rectangular cross-section are designed;

[0028] (2) Prefabricate the steel-concrete composite pipe in sections in the factory according to the requirements of the drawings; the steel-concrete composite pipe includes a bent rectangular cylindrical structural steel plate 1, and the two long sides of the steel-concrete composite pipe with a rectangular structure are respectively The upper side and the lower side of the rectangular cylindrical structural steel plate 1, the two short sides of the rectangular steel concrete composite pipe are the left side and the right side of the rectangular cylindrical structural steel...

Embodiment 2

[0041] Embodiment two: if figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the rectangular cylindrical structural steel plate 1 is formed by bending and welding a profiled steel plate, and the cross-section of the profiled steel plate is triangular, trapezoidal, arc-shaped, 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 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...
