Description

Technical Field

[0001] The present disclosure relates to the technical field of steel structure connection nodes, and in particular to a frame connection structure and a steel structure connection node. Background Art

[0002] The existing steel structure beam-column node connection method is generally through welding or bolt connection. The I-beam is fixed to the peripheral wall of the steel column by welding or bolt connection to form a frame structure. When the connection node between the I-beam and the steel column is subjected to force, the I-beam mainly bears pressure and shear force, and transmits the force to the steel column through the flange plate. When an earthquake occurs or under the action of external loads, the shear force on the I-beam will increase rapidly, and when the shear force on the I-beam reaches a certain level, it will cause the flange plate of the I-beam to buckle and become unstable, greatly reducing the safety of the building main body.

[0003] Existing technologies such as patent CN113136950A disclose a new type of prefabricated steel structure beam-column node and its construction. By bolting one end of the connecting piece to the upper flange of the steel beam and bolting the other end of the connecting piece to the steel column, when the connection node between the steel column and the steel beam is subjected to a large shear force, the above-mentioned steel structure beam-column node can increase the cross-sectional area of ​​the upper flange of the steel beam through the connecting piece to increase the stiffness of the upper flange of the steel beam, thereby improving the shear resistance of the steel beam and thereby improving the safety of the building main body.

[0004] However, the cross-sectional area of ​​the lower flange of the steel beam in the above-mentioned steel structure beam-column node is small, so that the stiffness of the lower flange of the steel beam is small. When the steel beam is subjected to a large shear force, the lower flange of the steel beam will be shear-deformed before the upper flange, thereby causing the steel beam to bend and become unstable, greatly reducing the safety of the building structure.
