The method is mainly characterized in that according to the actual included angle between the side face of a concrete column and the bottom face of a concrete beam, the steel plate included angle of the steel member used for reinforcing is determined, and the steel plate included angle of the steel member is larger than the actual included angle of the beam column; and a steel member is installed on the joint, a tensioning tool is used for tensioning the steel member, the upper surface of the steel member is made to be tightly attached to the lower surface of the concrete beam, bolts are fixed, and the concrete beam column joint is reinforced through the prestressed steel member. According to the reinforcing method, upward supporting prestress is applied to the beam, the prestress state of the additionally-arranged steel component during later reinforcing is achieved, the problem of stress lag existing in a traditional steel corbel reinforcing technology is solved, and the effect of reinforcing the beam-column joint can be fully exerted.
本发明公开了预应力钢构件加固混凝土梁柱节点方法，主要特征在于：根据混凝土柱侧面和混凝土梁底面的实际夹角，确定加固所用钢构件的钢板夹角，使得钢构件的钢板夹角大于梁柱实际夹角；在节点安装钢构件，利用张拉工具对钢构件进行张拉，使得钢构件上表面与混凝土梁的下表面贴紧，固定螺栓，完成预应力钢构件对混凝土梁柱节点的加固。本发明的加固方法对梁施加了向上支撑的预应力，实现了后期加固时增设的钢构件的预应力状态，克服了传统钢牛腿加固技术中存在的应力滞后问题，可以充分发挥加固梁柱节点的作用。
