Steel frame structure of composite beam

Abstract

The invention discloses a steel frame structure of a composite beam. The steel frame structure comprises an H-shaped steel column and a main beam, and one ends of composite members a are welded to upper and lower flange plates and a web plate of the H-shaped steel column. The composite members a comprise channel steel, steel plates are separately and vertically welded on the end portions of left and right flanges of the channel steel, and web plates of first T-shaped steel are vertically welded at the centers of web plates of the channel steel. A web plate of second T-shaped steel is welded onthe end portion of the main beam. Bolt holes of upper flange plates of the first T-shaped steel and the second T-shaped steel are connected with bolt holes of a first connecting plate through bolts,and bolt holes of the web plates of the first T-shaped steel and the second T-shaped steel are connected with bolt holes of a second connecting plate through bolts. Bolt holes of the end portions of the channel steel and the main beam are connected with bolt holes of third connecting plates through bolts. The steel frame structure of the composite beam has the advantages of direct on-site splicing, more convenient construction, time and labor saving, and construction cost saving.

Description

technical field [0001] The invention relates to a building assembly structure system, in particular to a steel frame structure of composite beams. Background technique [0002] With the growth of my country's national economy, steel production has become a major country in the world. Steel structure buildings are the main direction for the development and advancement of construction industrialization, and are also an important aspect of the development of green buildings. The beam-column joints are weak, the overall seismic performance is poor, the construction design of long-span concrete structures is difficult, and the applicability to buildings with a high number of floors and irregular planes and elevations is weak, which limits further development. [0003] At the same time, in the general reinforced concrete structure, in the process of removing the formwork of concrete beams and columns, tiny cracks will inevitably occur on the concrete surface, which will have a cer...

Problems solved by technology

The beam-column joints are weak, the overall seismic performance is poor, the construction design of long-span concrete structures is difficult, and the applicability to buildings with a high number of floors and irregular planes and elevations is weak, which limits further development

[0003] At the same time, in the general reinforced concrete structure, in the process of removing the formwork of concrete beams and columns, tiny cracks will inevitably occur on the concrete surface, which will have a certain impact on the mechanical properties of the structure; because the concrete is heavy and brittle High, and the brittleness gradually increases with the increase of strength. As the building goes higher and larger, the limitations of ordinary reinforced concrete structures become more prominent
