Embodiment 1

[0042] Such as Figure 1-4 As shown, it is a structural schematic diagram of the steel skeleton of the steel reinforced concrete column with a large aspect ratio of the present application. As can be seen from the figure, the frame body includes a steel frame 1, stirrups, studs 6 and longitudinal bars 7; The bone is composed of a steel frame flange 4 and a steel frame web 11; the steel frame web 11 is provided with a web hole 12, and the stirrups include multiple sets of U-shaped stirrups 3 and multiple closed stirrups 2; Each group of U-shaped stirrups 3 is composed of two U-shaped stirrups 3, which pass through the steel-frame web 11 from both sides of the steel-frame web 11 to connect to form a closed-structure stirrup; the closed stirrups 2 are placed in steel Both sides of the bone web 11 are tied to the longitudinal ribs 7 located on both sides of the steel frame web 11, close to the steel frame web 11 and the web hole 12; On the side, the pegs 6 and the stirrups are ve...

Embodiment 2

[0065] This embodiment takes a super high-rise residential building as an example, and the project adopts a reinforced concrete frame-core tube structure. The designed columns are the frame columns of the lower floors of the project, and the shear-span ratio is less than 2. If the stirrups do not pass through the web, the construction is simple, but the combination of the steel web and the concrete may be poor; if the stirrups pass through the web, a large number of holes are opened in the steel web, which weakens the steel web The strength of the slab will greatly increase the difficulty of construction and the construction period, but the combination of steel web and concrete may be better. According to the specification requirements, the steel reinforced concrete column stirrup spacing is 100mm. The structural form and construction method of the steel-reinforced concrete column with a large aspect ratio of the present invention are adopted. Set longitudinal reinforcement ...

Abstract

The invention discloses a steel-reinforced concrete column with high length-width ratio and a structure thereof and a construction method. The steel-reinforced concrete column with high length-width ratio mainly comprises a steel framework and concrete. The steel framework comprises a steel skeleton, stirrups, studs and longitudinal bars. The stirrups comprise multiple U-shaped stirrups and multiple sealed stirrups. The U-shaped stirrups pass through a steel-reinforced web. The sealed stirrups are placed at two sides of the steel-reinforced web and are tied to the longitudinal bars which are arranged at two sides of the steel-reinforced web and close to the steel-reinforced web and web holes. The studs are arranged at the longer side of the steel-reinforced web and are arranged in a staggered manner with the stirrups. The concrete is poured on the steel framework. According to the steel-reinforced concrete column with high length-width ratio and the structure thereof and the construction method, anti-seismic property of the steel-reinforced concrete column can be guaranteed; installation is convenient and fast such that web opening quantity, stirrup passing workload and welding workload are greatly minimized; construction procedures are greatly simplified; and the purpose of raising installation efficiency and construction quality is realized.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to a steel-reinforced concrete column with a large aspect ratio and its structure and construction method. Background technique [0002] With the acceleration of my country's urbanization process, urban land is becoming more and more tense, and urban buildings are gradually developing rapidly from high-rise to super high-rise; high-rise and super high-rise buildings have higher seismic requirements for structural vertical components. Rigidity and other requirements, usually can only increase the cross-sectional size of the column to form a "fat column", which affects the use of building space. Steel reinforced concrete is widely used in high-rise and super high-rise buildings because of its higher strength, stiffness, and ductility, and can reduce the cross-sectional area of ​​columns and save building space. [0003] However, in actual engineering, the size of steel-reinforced...
