Industrialized assembly type multi-storey and high-storey steel-structure tubular veneer self-resetting buckling-prevention herringbone bracing system

Abstract

The invention relates to an industrialized assembly type multi-storey and high-storey steel-structure tubular veneer self-resetting buckling-prevention herringbone 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. 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 industrial assembled steel structure herringbone 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 the construction quality is difficult to control. In recent years, there have been numerous engineering quality problems caused by the construction quality of steel structures. On-site welding is one of the important Factors, on-site welding quality is not easy to control, and cause great pollution to the environment. [0003] Traditional reinforced concrete structures require on-site binding of steel bars and concrete pouring, which requires a lot of labor and maintenance time, and the project cost is greatly increased. And a large amount of construction waste is caused when the building is demolished. [0004] In recent years, dom...

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 and heavy wet work workload caused by concrete peripheral restraint members (2-3)
