The invention discloses a newly-added beam and existing column joint annular steel plate hoop conversion connection structure, and belongs to the technical field of building reconstruction and reinforcement. The newly-added beam and existing column joint annular steel plate hoop conversion connection structure comprises an existing column, vertical steel plates are arranged on the periphery of the existing column and fixedly connected with the existing column through mechanical anchor bolts, and the adjacent vertical steel plates are connected through single-side groove partial penetration butt welds. Two annular steel plate hoops perpendicular to the vertical steel plates are arranged on the outer sides of the vertical steel plates, the two annular steel plate hoops correspondingly correspond to the positions of upper longitudinal steel bars and lower longitudinal steel bars of a newly-added beam, the annular steel plate hoops and the vertical steel plates are welded through fillet welds, the upper longitudinal steel bars and the lower longitudinal steel bars of the newly-added beam are correspondingly welded to the upper annular steel plate hoops and the lower annular steel plate hoops, and a plurality of bolt nails are welded to the vertical steel plates in the range of the newly-added beam. The reasonable joint connection mode is adopted, the force transmission and stress performance of the beam-column joint is effectively improved, and the safety performance and anti-seismic performance of the joint are obviously improved; and meanwhile, construction is easy and convenient, the cost is saved, and various defects existing in the conventional connection method are overcome and risks existing in the conventional connection method are reduced.
本发明公开了新增梁与既有柱节点环状钢板箍转换连接结构，包括既有柱，既有柱四周均设置有竖向钢板，竖向钢板通过机械锚栓与既有柱之间固定连接，相邻竖向钢板之间采用单边坡口部分熔透对接焊缝连接；竖向钢板外侧设置有与其垂直的两道环状钢板箍，两道环状钢板箍分别对应新增梁上下纵向钢筋的位置，环状钢板箍与竖向钢板采用角焊缝焊接，新增梁上下纵向钢筋分别与上下环形钢板箍焊接，新增梁截面范围内的竖向钢板上焊接有若干栓钉，本发明适用于建筑改造加固技术领域，合理的节点连接方式，有效改善梁柱节点处的传力和受力性能，明显增大节点的安全性能和抗震性能，同时做到施工简便，节约成本，解决以往常规连接做法存在的各类弊端和风险。
