This utility model discloses a steel-concrete composite column-beam joint connection structure, including a steel-concrete composite column main body. The outer surface of the steel-concrete composite column main body is provided with an I-shaped groove, which is distributed on both the left and right outer surfaces. An I-shaped beam is slidably inserted into the inner surface of the I-shaped groove of the steel-concrete composite column main body. A notch is provided on the outer end of the steel-concrete composite column main body at one of the I-shaped grooves, surrounding the outer end of the I-shaped groove. A corner positioning seat is fixedly connected to the outer surface of the steel-concrete composite column main body. The I-shaped beam adopts a through-type design, with its outer end welded and fixed to the surface of the steel-concrete composite column main body. The outer end is fixed by the corner positioning seat, and a wedge structure is provided on the inner side. After bolt fixing, the wedge can compress and tighten the I-shaped beam structure. During installation, it provides two-point support, ensuring stable support, reducing the number of threaded fasteners used, improving structural robustness, and enhancing support stability.
