Prestressed PEC steel frame beam connecting joint structure and method
The invention discloses a prestressed PEC steel frame beam connecting joint structure and method, and particularly relates to the field of fabricated constructions.The prestressed PEC steel frame beam connecting joint structure comprises a prefabricated PEC frame beam and a PEC column, the PEC frame beam and the PEC column are connected through high-strength bolts, and a PEC beam hoisting piece is arranged at the flange position of the PEC frame beam. The steel strand is combined with the PEC structure, the deflection value of the large-span PEC frame beam is greatly reduced due to the existence of the steel strand, on the premise that the bearing capacity is the same, the size of a beam joint is smaller, the construction cost is saved, and on the premise that the bearing capacity of a component is not weakened and the connecting workload of a joint area is not increased, the bending moment resistance of the beam column joint area is enhanced; and the requirements of strong nodes and weak components are met.
本发明公开了一种预应力PEC钢框梁连接节点构造及方法，具体涉及装配式建筑领域，该预应力PEC钢框梁连接节点的构造包括预制PEC框架梁和PEC柱，所述PEC框架梁与PEC柱通过高强螺栓连接，所述PEC框架梁的翼缘处设置有PEC梁吊装件，本发明中，钢绞线与PEC结构相结合，钢绞线的存在使得大跨度PEC框架梁扰度值大大减小，在相同承载力的前提下，梁节点尺寸更小，节省了建造成本，在保证构件的承载力不减弱且不增加节点区连接工作量的前提下，增强了梁柱节点区抵抗弯矩的能力，满足强节点弱构件的需求。
