Abstract

The invention discloses a connecting joint for an H-section steel partially encased recycled concrete composite column and an H-section steel girder. The connecting joint comprises the composite column and the H-section steel girder. The composite column comprises H-section steel, a plurality of transverse pull rods welded to flange plates on the two sides of the H-shaped steel in the length direction of the H-section steel, recycled concrete, side plates, a reinforcing plate and an additional plate. A containing cavity formed by an H-section steel web plate and the flange plates is filled with the recycled concrete, and the side plates, the reinforcing plate and the additional plate are welded to the joint of the grinder and the column. The side plates are parallel to the H-section steel web plate. The reinforcing plate is located at one side of the composite column, and the two ends of the reinforcing plate are welded to the side plates respectively. The additional plate is vertically welded to the flange plates of the H-section steel. A web plate of the H-section steel girder and the additional plate are welded, and flange plates of the H-section steel girder and the flange plates of the H-section steel are welded and fixed. According to the connecting joint, the side plates, the additional plate and the connecting plate are additionally welded to the joint of the girder and the column, so that the connecting joint has good ductility, the natural period of vibration of the structure is prolonged, the amplitude is reduced, and earthquake damage is reduced.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to a connection node between an H-shaped steel partially covered recycled concrete composite column and an H-shaped steel beam. Background technique [0002] The steel-concrete composite structure has the advantages of high bearing capacity, high rigidity, good seismic characteristics and dynamic performance, and has been widely used in various engineering structures, so the demand for H-shaped steel-concrete composite columns is also increasing. The construction of traditional embedded H-shaped steel concrete columns is difficult, especially at the joints of beams and columns, where steel and steel bars are densely packed, and the concrete is not easy to vibrate and compact there, which affects the pouring quality of the joints, resulting in Some related performance is not guaranteed. H-shaped steel partially outsourced recycled concrete composite column is a more effective way ...
