Stiff structure beam column and steel bar connecting structure

Abstract

The stiff structure beam column and steel bar connecting structure comprises first section steel column bodies and second section steel column bodies, connecting plates are welded to the outer walls of the first section steel column bodies at equal intervals, beam steel bars are transversely connected between every two adjacent first section steel column bodies, and column main bars are longitudinally connected to the outer sides of the second section steel column bodies; a first reinforcing plate is welded to the top of the left side of the connecting plate at the left end, a second reinforcing plate is welded to the top of the rear side of the connecting plate located at the rear end of the first section steel column body, a sleeve is further arranged at the top of the rear side of the connecting plate located at the rear end of the first section steel column body, and a beam steel bar is welded to the top of the first reinforcing plate. Beam steel bars are installed on the sleeves, steel beam brackets are welded to the outer wall of the second section steel column body at equal intervals, reinforcing beams are welded between the bottoms of the steel beam brackets and the outer wall of the second section steel column body, and the sleeves are arranged in the middles of the tops and the bottoms of the steel beam brackets. The connecting structure has the advantage that the beam steel bars and the section steel columns are stably connected.

Description

technical field [0001] The invention relates to the technical field of structural beam-column and steel bar structures, in particular to a rigid structure beam-column and steel bar connection structure. Background technique [0002] Large-scale building complexes have many special-shaped structures, large spans, and wide distribution of shaped steel columns and beams. The stiff structural beams and columns are densely reinforced, the local beams have up to four layers of gluten, and the joint reinforcement connections are complex. For complex section steel beam-column joints, the specification requires the connection between beam reinforcement and section steel column to use connecting plate or sleeve connection. If the single connection method of sleeve or connecting plate is used alone, when multi-layer beam reinforcement is connected to section steel column at the same time , On-site operation surface gap is narrow, construction is difficult, and the quality of steel bar...

AI Technical Summary

Problems solved by technology

The beam-column reinforcement of the rigid structure is dense, with up to four layers of local beam gluten, and the joint reinforcement connection is complicated

For complex steel beam-column joints, the code requires that the connection between the beam reinforcement and the steel column be connected by a connecting plate or a sleeve. , the gap between the on-site operation surface is narrow, the construction is difficult, and the quality of steel bar connection is difficult to guarantee

In addition, beams and columns in some locations of large building complexes are not perpendicular to the horizontal plane, and some beam reinforcements and steel columns are oblique. If sleeve connections are used, the accuracy of the sleeve must be consistent with the angle of the beam, and sleeve welding is required. The precision is very high, the factory welds the oblique sleeve type, due to the influence of welding stress, the welding angle of the sleeve is difficult to guarantee
