CFST-RC column uniform-section joint with PBL stiffening component and construction method of CFST-RC column uniform-section joint
The CFST-RC column uniform-section joint comprises a steel pipe concrete column, a reinforced concrete column and a reinforced concrete beam, the steel pipe concrete column comprises a steel pipe, a plurality of PBL stiff steel plates are distributed on the inner wall of the steel pipe in the circumferential direction, the PBL stiff steel plates are vertical, and the PBL stiff steel plates are perpendicular to the inner wall of the steel pipe; and shear-resistant ring ribs are arranged at different heights in the steel pipe, and each shear-resistant ring rib horizontally penetrates through all the PBL stiff steel plates. The joint has the beneficial effects that the pressure acting on the internal concrete can be directly transmitted to the reinforced concrete at the lower part of the joint; one part of the pressure borne by the steel pipe is transmitted to an end plate arranged in the steel pipe and transmitted to reinforced concrete on the lower portion of the joint through the end plate, and the other part of the pressure is transmitted to a PBL stiff steel plate welded to the inner wall of the steel pipe; at the moment, the PBL stiff steel plate bears the upper pressure and directly acts on part of the pressure transmitted by the steel pipe.
本发明涉及一种带PBL加劲构件的CFST‑RC柱等截面节点及其施工方法，包括钢管混凝土柱、钢筋混凝土柱和钢筋混凝土梁，钢管混凝土柱包括钢管，钢管内壁环向上分布有数道PBL劲性钢板，PBL劲性钢板竖直，且PBL劲性钢板垂直于钢管内壁；钢管内不同高度处设有抗剪环筋，每道抗剪环筋水平贯穿所有PBL劲性钢板。本发明的有益效果是：作用于内部混凝土的压力可直接传递至节点下部钢筋混凝土；钢管承受的压力一部分传递至钢管内部设置的端板，并由端板传递至节点下部钢筋混凝土，另一部分则传递至与钢管内壁焊接的PBL劲性钢板；此时PBL劲性钢板则承受上部压力直接作用于钢管传递的部分压力。
