Benefits of technology

[0023]The beneficial effects of this invention are as follows: the oblique concrete beam-column joint structure of this invention uses a column core tube and core pipe at the top of the concrete column as a steel frame structure to reliably ensure the anchorage of the support reinforcement of the orthogonal and oblique beams. The support reinforcement of the oblique beam welded to the core pipe effectively transfers the tensile force of the reinforcement to the steel frame structure that forms an integral part with the concrete column, replacing the method of using reinforcement and concrete anchorage for force transfer, which has the advantages of safety and reliability. The support reinforcement of the orthogonal beam is connected to the column core tube through the reinforcement plate. When the support reinforcement of the oblique beam encounters the core tube, the reinforcement bends downward and welds to the pre-welded core pipe inside. The reinforcement is welded to the plate on both sides, with a length of 5d. The support reinforcement of the surrounding oblique beams can be bent and welded into the column core tube and core pipe. The support reinforcement of the orthogonal beam is bent downward in advance before connecting to the reinforcement plate, ensuring that the support reinforcement of the oblique beam and the support reinforcement of the orthogonal beam do not intersect at the same elevation, and each is properly positioned. The support reinforcement of orthogonal and oblique beams does not overlap at the column joint, avoiding the phenomenon of reinforcement occupying space and being too dense to pour concrete. There is sufficient space inside the core tube for welding reinforcement and pouring and vibrating concrete at the top of the column. The reinforcement is arranged in an orderly and reasonable manner, which is safe, reliable, and convenient for construction, and improves the structural bearing capacity of the core area of ​​the orthogonal beam, oblique beam and column joint.

Abstract

The application discloses a skew concrete beam-column joint structure and a construction method thereof, which comprises a concrete column, a vertically arranged column core cylinder buried in the top of the concrete column, a plurality of lapping rib plates connected to the outside of the column core cylinder, a core pipe vertically arranged in the inside of the column core cylinder, the upper and lower ends of the core pipe being connected to the inner wall of the column core cylinder through flange plates respectively, a plurality of orthogonal beams connected to the top of the column, the end of the support rib of each orthogonal beam extending to the top of the column and lapping the rib plate on one side of the column core cylinder, a supporting rib rack connected to the bottom of the column core cylinder, and the rib of the supporting rib rack extending into the orthogonal beam; and a skew beam arranged between two orthogonal beams, the skew beam being connected to the top of the column, the end of the support rib of the skew beam extending above the core pipe and being bent downward to lap the inner wall of the core pipe. The application solves the problem that the multi-directional skew frame beam and the concrete column connecting joint cannot be normally poured due to the dense crossing of the steel bars.
