Construction method of prefabricated assembly type inter-pile tie beam
The invention discloses a construction method of a prefabricated assembly type inter-pile tie beam. The construction method comprises the steps of tie beam prefabrication, formwork support, tie beam placement, steel bar binding and formwork concrete pouring. A mode of hoisting the prefabricated tie beam is adopted to enable the prefabricated tie beam to penetrate into pile structures in a staggered mode, the prefabricated tie beam is supported through first supporting formworks which are arranged on the opposite inner sides of the adjacent pile structures at equal heights correspondingly, thenreinforcing steel bars are bound, the supporting formworks are perfected for cast-in-place construction, and connection of the tie beam and piles is completed. A cast-in-place and prefabrication combined mode is adopted for connecting the piles and the tie beam, investment of the supporting formwork is reduced, and the bridge construction quality, especially the appearance quality and the structural quality of bridge in-pile tie beam sections, is effectively improved under the condition that the design size of an original structure is not changed and the steel bar structure of the original structure is not changed, Wide application prospects are realized in the urban bridge construction, and the industrial development of buildings can be effectively promoted.
本发明公布了一种预制装配式柱间系梁的施工方法，该施工方法包括系梁预制、设模支护、系梁安放、钢筋绑扎以及设模浇砼步骤，采用吊装预制系梁的方式将预制系梁交错式穿插进入桩柱结构，并通过在相邻桩柱结构的对向内侧分别等高设置的第一支护模板对预制系梁进行支撑，而后绑扎钢筋、完善支护模板进行现浇施工，完成系梁与桩柱的连接。本发明采用现浇与预制结合的方式进行桩柱与系梁的连接，减少支护模板投入，并在不改变原结构设计尺寸，不改变原结构钢筋构造的情况下，有效提高桥梁施工质量，特别是桥梁柱间系梁段的外观质量和结构质量，在城市桥梁建设中具有广阔的应用前景，可有效推动建筑工业化发展。
