Hinge connection structure and method for supporting steel columns on steel beams

Abstract

The invention relates to a connection structure, in particular to a hinge connection structure and method for supporting steel columns on steel beams. The structure comprises the steel beams, the steel columns arranged above the steel beams and a connection plate arranged between the steel beams and the steel columns. The structure and the method have the following advantages and effects: the counter force at the bottoms of the steel columns is transferred to the direction of the strong axes of the steel beams by arranging the thickening connection plate with the same direction as a web of the strong axes of the steel beams and additionally arranging steel base plates avoiding lateral unstability of the connection plate; the node construction is simple and practical; the force is reliablytransferred; the steel beams are reasonably stressed; the stability of the nodes are enhanced; waste of the beam sections is avoided; the investment is reduced; convenience is provided for construction; and the requirements of connection are well met.

Description

technical field [0001] The invention relates to a connecting structure, in particular to a hinged connecting structure and a connecting method for supporting a steel column on a steel beam. technical background [0002] In industrial building structures, some steel platforms that are inconvenient to fall to the ground are often encountered. Steel beams are required to support steel columns to support the steel platform. When arranging steel columns, it is often encountered that the strong axis of the steel column is located in the direction of the weak axis of the steel beam. At this time, the steel beam is subjected to torque outside the plane. If the reaction force at the bottom of the column is large, it is easy to cause the out-of-plane instability of the steel beam. However, the existing steel beam supporting steel column connection structure has higher requirements on the steel beam section, resulting in waste of steel. Contents of the invention [0003] In order to ...

Problems solved by technology

At this time, the steel beam bears torque outside the plane. If the reaction force at the bottom of the column is large, it is easy to cause the steel beam to be unstable outside the plane. However, the existing steel beam supporting steel column connection structure has high requirements for the steel beam section, resulting in waste of steel.
