Large-span retard-bonded prestressed reinforced concrete structural beam
The invention discloses a long-span retard-bonded prestressed reinforced concrete structural beam which is of a retard-bonded prestressed concrete structure and comprises a long-span retard-bonded prestressed beam and a prestressed reinforcement auxiliary positioning device, the long-span retard-bonded prestressed beam comprises a frame beam and a frame column, retard-bonded prestressed reinforcements are inserted into the frame beam, and the frame column is connected with the retard-bonded prestressed reinforced concrete structural beam. The retard-bonded prestressed reinforcement comprises a steel strand, a retard-bonded adhesive and a PE sheath, a beam reinforcement playing a role in stress is arranged in the frame beam and comprises a longitudinal bar and a stirrup, the longitudinal bar and the stirrup are connected to form a reinforcement cage of the frame beam, and the prestressed reinforcement auxiliary positioning device is fixedly arranged below the longitudinal bar. The device is used for adjusting the distance between the retard-bonded prestressed reinforcement and the upper end face or the lower end face of the frame beam. According to the invention, a reliable design scheme is provided for the vast number of design and building employees by providing design parameters, design structures and related material characteristic selections required by the retard-bonded prestressed reinforcement long-span beam with the length of 21-24 meters.
本发明公开了一种大跨度缓粘结预应力钢筋混凝土结构梁，为缓粘结预应力混凝土结构，包括大跨度缓粘结预应力梁和预应力钢筋辅助定位装置，大跨度缓粘结预应力梁包括框架梁和框架柱，框架梁内穿插有缓粘结预应力钢筋，缓粘结预应力钢筋包括钢绞线、缓粘结胶粘剂和PE护套，框架梁内设有起受力作用的梁钢筋，梁钢筋包括纵筋和箍筋，纵筋和箍筋连接组成框架梁的钢筋笼，预应力钢筋辅助定位装置固装在纵筋下方，用于调节缓粘结预应力钢筋与框架梁的上端面或下端面之间的距离。本发明通过提供长度为21～24米的缓粘结预应力钢筋大跨度梁所需要的设计参数、设计结构和相关的材料特性选择，为广大设计和建筑从业人员提供了一种可靠的设计方案。
