Connection joint structure of steel column supported by steel beams

Abstract

The invention discloses a connection joint structure of a steel column supported by steel beams, and relates to the field of constructional engineering. The connection joint structure of the steel column supported by the steel beams has reasonable force and force transferring. According to the technical scheme, the connection joint structure of the steel column supported by the steel beams comprises a main beam, secondary beams and the steel column, two sides of the main beam are separately in rigid connection with the secondary beams, the main beam and the secondary beams are crossed and arranged horizontally, the top surface of the main beam at the crossed position is connected with the steel column, a column base bottom plate is arranged at the lower end of the steel column, the columnbase bottom plate is in rigid connection with the top surface of the main beam, and the steel column is vertically arranged. According to the connection joint structure of the steel column supported by the steel beams, column base counterforce of the steel column can be well transferred to the steel beams, so that force of the steel beam is reasonable, and the requirements of a space structure aremet; and meanwhile, the stability of a connection joint is enhanced, the size of sections of the steel beams can be reasonably selected according to the practical situation, and the economic requirements are met.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a steel structure connecting structure. Background technique [0002] With the continuous development of the economy, there are more and more high-rise and multi-storey steel structure buildings, and the comprehensive functions of the buildings are getting stronger and stronger. The lower floors of the building are closely connected with the outside, especially the urban street-facing buildings, where public rooms such as halls, commerce, and entertainment are set up. There will be houses, apartments and other small bay buildings on each floor, which requires a transition floor on the upper and lower floors to complete the change of the structural form from the upper floor to the lower floor. Beam-supported column transfer floor structure is a relatively common structural form at present. [0003] The authorized announcement number is CN206987048U, and the patent date of...

Problems solved by technology

This node structure is more suitable when the load of the superstructure is small. When the load of the superstructure is large, the node cannot meet the structural force requirements.
