Construction method for continuous beam side span small-rigidity double-column-pier counterweight-free closure
The invention discloses a construction method for continuous beam side span small-rigidity double-column pier counterweight-free closure, which comprises the following steps: in the side pier construction process, respectively reserving center penetrating holes in the peripheral walls of two pier columns, then arranging steel bars in the preformed holes in a penetrating manner, vertically arranging a plurality of suspenders in pre-buried holes of a cast-in-place box beam in a penetrating manner, and transversely distributing the suspenders at intervals; the transverse distribution beams are horizontally suspended at the lower ends of the suspenders, the upper surfaces of the transverse distribution beams are flush with the upper sides of the steel bars, and the longitudinal distribution beams are erected on the steel bars and the transverse distribution beams; a plurality of Bailey beams which are transversely arranged are erected above the longitudinal distribution beams, and the Bailey beams are longitudinally distributed; a plurality of longitudinally-arranged bearing beams are arranged above the bailey beams, the bearing beams, the lighted beams and the distribution beams jointly form a supporting and hanging combined construction platform, then a formwork is built on the construction platform, steel bars are bound on the construction platform, then concrete is poured, and continuous beam closure construction is completed. And the problems of construction bias pressure of the pier-side bracket and repeated stacking balance weight can be reduced.
本申请公开了一种连续梁边跨小刚度双柱墩无配重合拢的施工方法，通过在边墩施工过程中，分别在两个墩柱周壁预留穿心孔，接着在预留孔处穿设钢棒，并在现浇箱梁的预埋孔中竖直穿设若干吊杆，若干吊杆横向间隔分布，向分配梁水平悬吊在若干根吊杆下端，横向分配梁上表面与钢棒上侧齐平，纵向分配梁架设在钢棒与横向分配梁上；在若干纵向分配梁上方搭设若干横向设置的贝雷梁，若干贝雷梁纵向分布；在贝雷梁上方设置若干纵向设置的承重梁，承重梁、被雷梁以及分配梁共同组成支吊结合的施工平台，然后在施工平台上搭建模板，在施工平台上绑扎钢筋，然后浇筑混凝土，并完成连续梁合拢施工，有利于减少墩旁托架施工偏压及反复堆载配重的问题。
