Industrialized prefabricated multiple, high-rise steel structure channel steel self-resetting anti-buckling central support system

Abstract

The invention relates to an industrialized assembly type multi-storey and high-storey steel-structure channel steel self-resetting buckling-prevention central bracing system which can be installed quickly. The system comprises a steel-structure body grillage, self-resetting bracing members and column systems. The steel-structure body grillage comprises base grillages and floors. When the system is implemented, wide beams (3), narrow beams (4) and column bases (7) are assembled in a factory to form the base grillages. The base grillages and the floors are constructed into a whole. The wide beams and the narrow beams are respectively formed by welding channel steel in the factory. Pipelines pass through the position between web channel steel of the wide beams and the web channel steel of the narrow beams, so that the A base grillages, the B base grillage and the C base grillage are formed. High-strength bolt connection and partial welding are adopted for the junctions between the base grillages and the column bases and the junctions between the wide beams and the narrow beams. The column bases and columns are in flanged connection through high-strength bolts. The structural system has the advantages that the construction speed is high, structural bearing capacity is high, the anti-sidesway capacity is good, and no pollution is caused.

Description

technical field [0001] The invention relates to a novel structural system, in particular to an industrialized assembled steel structure central support system applied in the construction field. Background technique [0002] The construction of ordinary steel structures uses a lot of welding on site, which not only affects the construction speed but also makes it difficult to control the construction quality. In recent years, there have been numerous engineering quality problems caused by the construction quality of steel structures, and on-site welding is one of the most important Factors, on-site welding quality is not easy to control, and it causes great pollution to the environment. [0003] The traditional reinforced concrete structure requires on-site binding of steel bars and pouring of concrete, which requires a lot of labor and maintenance time, and the project cost is greatly increased. And a large amount of construction waste is generated when the building is demo...

Problems solved by technology

However, the residual deformation produced by traditional buckling-resistant braces under strong earthquakes is still unrecoverable, and traditional buckling-resistant braces also have many problems such as difficult control of machining accuracy caused by concrete peripheral restraint members, and heavy wet work workload.
