Problems solved by technology

[0005] Although the hinge joints in the construction project 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 safety hazard

Abstract

The invention discloses a beam column hinged joint, and belongs to the field of steel structures. the beam column hinged joint is fixed to a steel column through a first fixing assembly and a second fixing assembly. Due to the fact that a second angle plate and a second plate body are arranged on the two sides of a web, close to a steel beam, of a first flange or a second flange, and the second angle plate and the second plate body support a web of the steel beam, the steel beam can not achieve rotation with the direction parallel to the first flange, the second flange and the web as the axis.Due to the clamping and fixing of the second fixing assembly, and the hole diameters of a first through hole, a third through hole and a second through hole are all larger than the diameter of a screw of a first bolt, the steel beam can use the second fixing assembly as a supporting point to achieve the rotation with the direction parallel to the first flange and the second flange and perpendicular to the web plate as the axis when being exerted by external forces. The structure of the beam column hinged joint more accords with the structure of a hinged joint in an ideal state, the safety ofthe structure is improved, and the safety hazards on the structure are removed.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a beam-column hinge joint. 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, such as fi...
