Prefabricated assembly type prestressed column pier and assembly method
The invention discloses a prefabricated assembly type prestressed column pier, and belongs to the field of bridge engineering. The pier is formed by assembling a lower column section, an upper column section, a straining beam section, a cover beam and a straining beam reinforced concrete prefabricated component. The lower column section, the upper column section and the straining beam section between the lower column section and the upper column section jointly form the pier columns, and the pier columns are connected through straining beams. Components are rapidly installed in place through positioners, all the components are tensioned and anchored through prestressed steel cables, joints are connected through post-pouring concrete, post-pouring sections adopt pre-embedded steel plates to replace pre-embedded steel bars, and the fabricated prestressed column type pier is formed through on-site assembly. The processes of cast-in-place concrete steel bar binding, formwork erecting, concrete pouring, curing, formwork disassembling and the like are omitted, and the site construction period is shortened. The post-cast section adopts the pre-embedded steel plate, the installation speed is high, the defect of high-altitude operation difficulty in pre-embedded steel bar welding is overcome, a positioner is adopted for component assembly for quick in-place, and the problem that traditional hoisting in-place adjustment is difficult is solved.
本发明公开了一种预制装配式预应力柱式桥墩，属于桥梁工程领域。桥墩由下柱段、上柱段、系梁段、盖梁、系梁钢筋混凝土预制构件装配而成。下柱段和上柱段与之间的系梁段共同组成墩柱，墩柱之间采用系梁连接。构件之间采用定位器快速安装就位，各构件采用预应力钢索张拉锚固，接缝采用后浇混凝土连接，后浇段采用预埋钢板代替预埋钢筋，现场组装构成装配式预应力柱式桥墩。减少了现浇混凝土绑扎钢筋、支模、浇筑混凝土、养护、拆模等工序，缩短了现场施工的工期。后浇段采用预埋钢板，安装速度快，克服了预埋钢筋焊接高空作业困难的缺陷，构件装配采用定位器快速就位，解决了传统吊装就位调整困难的问题。
