Fabricated pre-tensioning method prestressed beam column connecting joint
The embodiment of the invention provides an assembly type pre-tensioning method prestress beam column connecting joint. The assembly type pre-tensioning method prestress beam column connecting joint comprises a concrete frame column and a pre-tensioning method prestress superposed beam. The top of the concrete frame column is provided with the column cap, and the superposed beam is directly placed on the column cap, so that a superposed beam supporting frame is omitted; the column cap can provide safety reserve for shear resistance of a vertical seam of a beam end node in the construction stage, and can be integrally cast with a superposed beam end in the use stage to form an expanded node, so that the anti-seismic property of the node is enhanced; the steel strands extending out of the ends of the superposed beams are directly bent and anchored in the connecting joints, in the construction stage, the pre-tensioning method prestress superposed beams are directly placed on the column caps to form a simple support model, the high-strength steel strands at the beam bottoms are fully used for bearing bending moment generated by self weight in the construction stage, and support negative reinforcements are reduced; the steel strands can easily avoid the joint steel bars, construction is convenient, the joint construction quality is guaranteed, meanwhile, the building difficulty can be lowered, and the manufacturing cost is reduced.
本申请的实施例提供了一种装配式先张法预应力梁柱连接节点，包括混凝土框架柱和先张法预应力叠合梁；在混凝土框架柱的顶部设置柱帽，并将叠合梁直接搁置在柱帽上，免去了叠合梁支撑架；柱帽在施工阶段能够为梁端节点竖缝抗剪提供安全储备，在使用阶段能够与叠合梁端整浇形成扩大节点，增强节点的抗震性能；将叠合梁端部伸出的钢绞线直接弯折锚固于连接节点内，在施工阶段，先张法预应力叠合梁直接搁置在柱帽上形成简支模型，充分利用梁底高强钢绞线承担施工阶段自重产生的弯矩，减少支座负筋；钢绞线能够轻松避让节点钢筋，施工方便，在保证节点施工质量的同时，还能够降低建造难度，减少造价。
