Cable-stayed bridge side span cast-in-place beam support and using method
The invention discloses a cable-stayed bridge side span cast-in-place beam support and a using method. The using method comprises the following construction steps that S1, a construction site is leveled; s2, pile position lofting; s3, pile foundation hole forming; s4, hoisting and placing the reinforcement cage; s5, pouring concrete; s6, mounting a support steel pipe stand column; s7, bracket supporting columns are installed; s8, an unloading device is installed; s9, mounting an upper structure of the bracket; s10, pre-pressing and checking and accepting the bracket; s11, constructing a beam body; s12, beam bottom supports except the bracket supporting columns are dismantled; s13, a stay cable is hung and preliminarily tensioned; s14, the bracket supporting columns are dismantled; the material part of the support for construction can be dismantled in advance after beam body pouring is completed and after tension grouting is conducted and before a cable is hung, the occupied time of the support material is effectively shortened, the construction cost is reduced, and the turnover utilization rate of the material is increased.
本发明公开了一种斜拉桥边跨现浇梁支架及使用方法，包括以下施工步骤：S1.施工场地平整；S2.桩位放样；S3.桩基成孔；S4.钢筋笼吊放；S5.混凝土灌注；S6.支架钢管立柱安装；S7.牛腿支撑柱安装；S8.卸荷装置安装；S9.支架上部结构安装；S10.支架预压及验收；S11.梁体施工；S12.拆除除牛腿支撑柱以外的梁底支架；S13.斜拉索挂设并初张拉；S14.拆除牛腿支撑柱；能够在梁体浇注完成并张拉压浆后挂索前，提前将施工用支架的材料部分拆除，有效降低了支架材料的占用时间，降低了施工成本，提高了材料的周转利用率。
