Steel structure connection point installation construction technology

Abstract

The invention relates to the technical field of steel structure construction, and discloses a steel structure connecting point installation construction technology which comprises the following steps: S1, selecting a high-strength bolt; s2, checking calculation of a web plate and an end plate of the component; s3, component friction surface treatment and high-strength bolt reinspection are carried out; s4, mounting a base plate; and S5, high-strength bolts are assembled. According to the method, installation of the steel structure connecting points is achieved through high-strength bolt selection, checking calculation of a component web and an end plate, component friction surface treatment, high-strength bolt reinspection, base plate installation and high-strength bolt assembly in sequence, and the bearing capacity of the high-strength bolts under different stress conditions is calculated; according to the method, the strength and the bearing capacity of the connecting points meet actual requirements by calculating the strength of the connecting points, the bearing capacity of the node domain and the bearing capacity of the connecting positions of the web plates and the end plates of the components, so that the steel structure connecting points are not prone to deformation and displacement, and the safety of steel structure buildings is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a steel structure connection point installation and construction process. Background technology [0002] In recent years, China's construction industry has developed rapidly. In construction engineering, steel structure has small section and light weight, and can be installed automatically, standardized and mechanized quickly. Therefore, it is widely used. The connection methods of steel structure include rigid connection, hinged connection and semi-rigid connection; Among them, there are usually three types of rigid connection, namely welding, riveting and bolt connection. Bolt connection includes ordinary bolts and high-strength bolts. High-strength bolts are widely used because of their advantages of simple construction, good stress, removable replacement, fatigue resistance, not easy to slip and high safety. [0003] The Chinese patent discloses a fabricated s...

Problems solved by technology

[0003] The Chinese patent discloses an assembled steel structure beam-column joint structure and assembly method (authorized announcement number CN106988418B). The rapid assembly process between the beams, and the assembly between the steel pipe column and the steel pipe beam are more stable, but it does not check the connection points of the bolts and components during the assembly, which may lead to insufficient bearing capacity of the steel structure, which in turn leads to The connection point of the steel structure is deformed and thought
