Bracket and sleeve combined steel reinforced concrete beam-column joint structure and construction method
The invention belongs to the technical field of cast-in-place concrete structure engineering, and discloses a bracket and sleeve combined steel reinforced concrete beam column joint structure and a construction method.The joint structure is provided with a first bracket and a second bracket which are different in size, and meanwhile the position of a sleeve is ingeniously arranged; connection and fixation of steel bars in a steel reinforced concrete beam-column joint area are achieved. When the reinforced concrete beam surface bars and the bottom bars are connected and fixed, the second surface bars are installed firstly, then the first surface bars are installed, the second bottom bars are installed firstly, then the first bottom bars are installed, the steel bars are connected with the sleeves at the respective positions and the corresponding bracket flange plate faces from inside to outside, and connection and fixing of the steel bars and the section steel column are achieved. In addition, a second sleeve and a fourth sleeve are arranged on the first bracket and the second bracket respectively to be connected with a second vertical steel bar, the connecting quality of the vertical steel bars and the brackets is ensured, stiffening strips are arranged on the sleeves in the same vertical direction, the overall pressure bearing performance of the vertical steel bars in the vertical direction is ensured, structural stress is facilitated, reliability is high, the construction difficulty is reduced, and the construction efficiency is improved. The building period is shortened.
本发明属于现浇混凝土结构工程技术领域，公开了一种牛腿套筒组合型钢混凝土梁柱节点结构及施工方法，其中，节点结构通过设置大小不同的第一牛腿和第二牛腿，同时巧妙设置套筒的位置，实现型钢混凝土梁柱节点区域钢筋的连接固定。在钢筋混凝土梁面筋和底筋连接固定时，先安装第二面筋再安装第一面筋，先安装第二底筋再安装第一底筋，钢筋由内及外连接上各自位置的套筒和对应的牛腿翼缘板面，实现钢筋与型钢柱的连接固定。另外在第一牛腿和第二牛腿上分别设置第二套筒和第四套筒连接第二竖向钢筋，确保竖向钢筋与牛腿的连接质量，并在各套筒同一竖向设置加劲条，确保了竖向钢筋在垂直方向上的整体承压性，有利于结构受力，可靠性强，降低了施工难度，减少建筑周期。
