Problems solved by technology

[0005] Although the hinge joints in actual engineering can realize the connection between the steel beam and the steel column, but in this way, the steel beam cannot rotate around the axis parallel to the two flanges and perpendicular to the web, which is inconsistent with the theoretical model. There is a certain difference in the force of the system and the calculation setting, which has caused a certain safety hazard

Abstract

The invention discloses a beam-column hinged connection joint and belongs to the field of steel structures. The beam-column hinged connection joint utilizes a fixing assembly, a fixing bracket and a first elastic buffering piece and is fixed to a steel column through the fixing assembly and a stiffening plate. A second plate body and a third plate body are arranged on the inner side plate face ofa first plate body, a first flange of a steel beam is clamped through the fixing assembly and the stiffening plate, so that the first flange of the steel beam is fixed between the second plate body and the third plate body, and the steel beam cannot rotate around the direction, parallel to the first flange, a second flange and a web, serving as the axis. The second flange of the steel beam is connected to a top plate, thus when the steel beam is under outer force, the fixing bracket can serve as a supporting point, by squeezing the first elastic buffering piece, the steel beam rotates around the direction, perpendicular to the first flange, the second flange and the web, serving as the axis, the structural safety is improved, and the structural potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a beam-column hinge connection node. Background technique [0002] Simply supported beam is a beam structure commonly used in engineering, and the steel beam is connected to the steel column through hinged nodes at both ends. The schematic diagram of the hinged joint under ideal conditions is as follows: figure 1 As shown, by setting a horizontal support seat a and two rods b on the surface of the steel column, one end of the steel beam can be erected on the support seat a and fixed by the rod body b. The steel beam can realize: (1) winding The axis is free to rotate along the direction parallel to the two flanges and perpendicular to the web, such as figure 1 (2) It cannot rotate freely around the axis parallel to the direction of the two flanges and the web, such as figure 1 in the z-axis. [0003] Schematic diagram of the joint joints commonly used in actual engineering, su...
