Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] as attached figure 1 , 2 , shown in 3, a kind of reinforced concrete column-reinforced concrete beam joint connection method, comprises upper flange plate 1, lower flange plate 2, is connected with web 3 between upper flange plate and lower flange plate, on upper flange plate Weld the studs 5 and the angle steel corbels 4 on the outside of the flange plate and the lower flange plate, weld the beam longitudinal reinforcement 7 to the angle steel corbel plate 4, and weld the upper and lower flange plates Rebar horizontal tie rod 6. The reinforcement horizontal tie bar 6 is arranged parallel to the web 3 . The part of the beam longitudinal reinforcement that needs to be welded is welded on the angle steel corbel plate in an L shape, and the double-sided welding length is 5 times the diameter of the beam longitudinal reinforcement.

Abstract

The invention discloses a steel-reinforced concrete column and reinforced concrete beam node connecting method, which comprises an upper flange plate and a lower flange plate, wherein a web plate is connected between the upper flange plate and the lower flange plate; male pins and angle steel corbel plates are welded at the outer sides of the upper flange plate and the lower flange plate; a beam longitudinal steel bar is welded on each angle steel corbel plate; and a steel bar horizonal tie bar is welded between the upper flange plate and the lower flange plate. The steel-reinforced concrete column and reinforced concrete beam node connecting method designed by the invention has the advantages that firstly, the angle steel corbel plates and reinforced concrete beams are welded; the problemthat the anchoring length and the welding length of the beam longitudinal steel bars and the angle steel corbel plates are insufficient due to specific dimension of a section steel column is avoided;then, the steel bar horizonal tie bar is used; the section steel column and beam welding node is prevented from generating flange buckling, i.e., the node generates local instability; meanwhile, thepunching in flanges is avoided; and the rigidity and the intensity of the steel-reinforced concrete column and reinforced concrete beam node are ensured.

Description

technical field [0001] The invention relates to a concrete column node connection method, in particular to a steel concrete column-reinforced concrete beam node connection method, and belongs to the technical field of building structures. Background technique [0002] Among the connection nodes between steel-reinforced concrete columns and reinforced concrete beams, there are two connection methods commonly used in the prior art: one is a connection node between steel-concrete columns and reinforced concrete beams provided by the patent application number 201420543333.4, which uses The form of through-bars solves the joint problem of the steel concrete column and the reinforced concrete beam, but the stability of the steel column decreases after the hole is opened, which weakens the structural strength of the steel flange plate; A steel concrete column and cast-in-place reinforced concrete beam joint and its construction method are connected by sleeves, which require precise...
