H-shaped steel beam and H-shaped steel column strong-axis variable-beam height fabricated node and construction method thereof

Abstract

The invention discloses an H-shaped steel beam and H-shaped steel column strong-axis variable-beam height fabricated node and a construction method thereof. The node comprises an H-shaped steel column, an H-shaped steel beam, a T-shaped connection piece, an L-shaped connection piece and bolts; the T-shaped connection piece consists of an upper flange plate connection plate which is arranged horizontally, and a web connection plate which is perpendicular to the bottom surface of the upper flange plate connection plate; the upper flange plate connection plate is connected with an upper flange plate through the bolts; the web connection plate is connected with a web through the bolts; the L-shaped connection piece consists of a lower flange plate connection plate which is arranged horizontally and a column connection plate which is perpendicular to the lower flange plate connection plate downward; the lower flange plate connection plate is connected with a lower flange plate through the bolts; and the column connection plate is connected with a column flange plate of the H-shaped steel column through the bolts. All accessories required by the node are prefabricated in a factory, the requirement of equal-strength connection in the process of changing the section of the H-shaped steel beam in a certain range can be met, high-strength bolts are adopted by a construction field node so as to realize the fabricated connection, and the node is high in rigidity and high in connection speed, and can meet the requirement of the fabricated construction of a steel structure.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a steel structure beam-column connection node and a construction method thereof. Background technique [0002] In multi-story and high-rise steel structures, H-shaped steel beams and H-shaped steel columns are used as the main load-bearing components, and the nodes connecting H-shaped steel beams and H-shaped steel columns play the role of transmitting beams, column bending moments, and shear forces. The overall mechanical performance has a significant impact. The full-welded connection and bolt-welded connection of H-shaped steel beams and columns have high structural connection stiffness and good mechanical performance, but the site construction is difficult and expensive, and cannot meet the requirements of steel structure construction efficiency. In the existing prefabricated steel structure, although the way of bolting joints is convenient for...
