Abstract

The invention discloses a connection joint of a box-shaped steel beam and a concrete filled steel tubular column and a construction method of the connection joint. The connection joint is composed of the box-shaped steel beam, the concrete filled steel tubular column and a force transferring assembly. The force transferring assembly comprises a force transferring component, a beam force transferring component and a bolt and nut locking suite. The end of the box-shaped steel beam and the beam force transferring component form a shearing force transferring structure. The shearing force transferring structure is composed of an upper flange, a lower flange, two outer webs, two inner webs, two front cross rib plates, two middle cross rib plates and two rear cross rib plates. Damage to the structural integrity of the flanges of the box-shaped steel beam due to tapping does not affect the bending moment transferring effect or weaken the connection joint, so that the connection joint is more reliable in quality, clearer in force transferring and more uniform in stress. Bolts of the bolt and nut locking suite are put into installation openings without tapping in the construction method of the connection joint, so that the connection joint is easier and more convenient to construct and higher in operability.

Description

technical field [0001] The invention relates to a connection node between a box-shaped steel beam and a steel tube concrete column, and a construction method for the connection node. Background technique [0002] The box section, like the H section, is an ideal section for beam members mainly resistant to bending and shearing. Compared with the H section, the box section has better axial and torsional resistance; Due to its high strength and good seismic performance, it has been widely used in high-rise and super high-rise building structures. [0003] The connection between the steel beam and the steel pipe concrete column is the key to the engineering design and construction. The joint structure generally adopts the combination of bolt and welding, that is, the flange of the steel beam and the ring plate of the steel pipe column are welded, and the web and the steel pipe column are connected by bolts on the connecting plate. , which has the advantages of high safety, high...
