Non-web-bar UHPC (Ultra High Performance Concrete) segment spliced beam structure reinforced at splicing seam and construction method thereof
The invention relates to a web-bar-free UHPC (Ultra High Performance Concrete) section spliced beam structure reinforced at splicing seams and a construction method thereof, a plurality of sections of UHPC section beams without shear reinforcements are spliced in sequence, the UHPC section beams are connected by prestressed steel strands, and the splicing seams are formed between the adjacent UHPC section beams; groups of high-strength bolts are arranged on the two sides of the splicing seam and the two adjacent UHPC segmental beams; for each UHPC section beam, a plurality of high-strength bolts are pre-buried at the bottom and the lower part of the side surface of the UHPC section beam; bolt holes are formed in the reinforcing steel plates, a group of high-strength bolts penetrate through the bolt holes of one reinforcing steel plate, and the ends of the high-strength bolts are locked through nuts; and a fiber reinforced composite material layer is adhered to the upper part of the side surface of the UHPC segmental beam to cover a splicing seam. According to the web-rib-free UHPC section assembled beam, the stress of the joints is enhanced, all UHPC section beams can form overall stress, the bearing capacity of the web-rib-free UHPC section assembled beam is improved, and the web-rib-free UHPC section assembled beam belongs to the field of prefabricated bridge structures.
本发明涉及一种在拼接缝处加强的无腹筋UHPC节段拼装梁结构及其建造方法，将多段没有配置抗剪钢筋的UHPC节段梁依次拼装，预应力钢绞线将各UHPC节段梁连接，相邻UHPC节段梁之间形成拼接缝；在拼接缝两侧，相邻两段UHPC节段梁上设置成组的高强螺栓；对于每段UHPC节段梁，多根高强螺栓预埋在UHPC节段梁的底部和侧面下部；加强钢板上设置螺栓孔，一组高强螺栓穿过一块加强钢板的螺栓孔，高强螺栓的端部通过螺帽锁紧；UHPC节段梁的侧面上部粘贴纤维增强复合材料层将拼接缝覆盖。本发明加强接缝受力，使各UHPC节段梁能形成整体受力，提高无腹筋UHPC节段拼装梁的承载能力，属于预制桥梁结构领域。
