Hollow special-shaped column high-rise fabricated steel structural system

Abstract

The invention discloses a hollow special-shaped column high-rise fabricated steel structural system which comprises a special-shaped column and mounting grooves and further comprises a first connecting seat composed of a first mounting sleeve, a first receding groove and a first threaded sleeve, and a second connecting seat composed of a second mounting sleeve, a connecting sleeve, a second receding groove and a second threaded sleeve. According to the hollow special-shaped column high-rise fabricated steel structural system, the structure is ingenious, and the function is powerful; firstly, through the stable bridging structure effect, quick assembly is achieved, the overall stability of a steel structure is further greatly improved, and the construction speed is increased; secondly, through sunken design of the special-shaped column, concrete can be poured into the special-shaped column, and effective filling of subsequent concrete pouring is reinforced; and finally, the quakeproof effect and stability of a whole building are improved, and application and popularization in industries are facilitated.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a hollow special-shaped column multi-story assembled steel structure system. Background technique [0002] The steel tube concrete structure is composed of steel tubes filled with concrete. It utilizes the interaction between steel tubes and concrete in the process of stress, that is, the restraint of the steel tubes on the core concrete, so that the concrete is in a state of multi-directional compression, so that the concrete The strength is improved and the ductility is improved; at the same time, due to the existence of concrete, the premature local buckling of the steel pipe can be delayed or avoided to ensure the full performance of the steel performance. In the construction process of steel pipe concrete, the steel pipe can be used as the pouring formwork of its core concrete. Compared with reinforced concrete, it can save the cost of the formwork and speed u...

Problems solved by technology

[0003] According to the above, the current traditional steel structure is generally simple in structure, and most of them are composed of square and rectangular steel pipe bridges. Realizing the pouring and filling of concrete reduces the overall seismic effect and strength of the building. In addition, most of the existing steel structure bridging methods are welding, which is not only time-consuming and laborious, but also has high requirements for the technical level of the staff, which increases the The investment in the project is not conducive to the promotion and application of the industry. In view of the above defects, it is necessary to design a multi-story fabricated steel structure system with hollow special-shaped columns
