Orthogonal connection node of reinforced concrete beam and large-section box-shaped steel reinforced concrete column
The invention relates to an orthogonal connection node of a reinforced concrete beam and a large-section box-shaped steel reinforced concrete column, which comprises the box-shaped steel reinforced concrete column, a steel corbel, the reinforced concrete beam and a horizontal haunching part, and the reinforced concrete beam is in orthogonal connection with the box-shaped steel reinforced concrete column; the steel corbel is I-shaped steel and is welded on the box-shaped profile steel in the column; the beam horizontal haunching part comprises a stressed steel bar framework and concrete; part of longitudinal bars in the reinforced concrete beam are welded to flanges of the steel corbels, and part of the longitudinal bars are bent and wound around the columnar steel to be anchored. According to the orthogonal connection joint of the reinforced concrete beam and the large-section box-shaped steel reinforced concrete column, the problems that the bending angle of a beam longitudinal bar at a traditional connection joint of the large-section box-shaped steel reinforced concrete column and the reinforced concrete beam is large, and the steel bar is difficult to machine and place during construction are solved; meanwhile, the problem that when the turning angle of the tensile longitudinal bar on the upper portion of the concrete beam is large, outward pressure is caused to concrete at the connecting position of the beam and the column, and the concrete at the connecting position cracks is solved.
本发明是涉及一种钢筋混凝土梁与大截面箱形型钢混凝土柱正交连接节点，包括：箱形型钢混凝土柱、钢牛腿、钢筋混凝土梁及水平加腋部分，钢筋混凝土梁与箱形型钢混凝土柱正交连接；钢牛腿为工字钢，焊接于柱中箱形型钢上；梁水平加腋部分包括受力钢筋骨架和混凝土；钢筋混凝土梁中部分纵筋与钢牛腿翼缘焊接，部分弯折绕过柱型钢进行锚固。本钢筋混凝土梁与大截面箱形型钢混凝土柱正交连接节点，避免了传统的大截面箱形型钢混凝土柱和钢筋混凝土梁连接节点处梁纵筋弯折角度较大，钢筋加工困难，施工时难以放置的问题，同时也避免了混凝土梁上部受拉纵筋转折角度较大时，会对梁柱连接处混凝土造成向外压力，导致该连接处混凝土会产生开裂问题。
