Bridge stand column support-free construction method
A bridge stand column support-free construction method comprises the steps: processing of a stand column reinforcement cage: the stand column reinforcement cage is machined through a reinforcement cage jig frame; measuring the pre-embedded position of the stand column: lofting the direction line of the outer side line of the stand column onto a bearing platform template, and pulling out the central outline of the stand column by using a fine line to serve as a reference line of a stand column pre-embedded reinforcement cage; and integrally hoisting the stand column reinforcement cage: inserting the reinforcement cage into the bearing platform and not installing opposite-pull hook ribs and inner stirrups of the part above the bearing platform surface, binding the part of steel bars insertedinto the bearing platform after the stand column reinforcement cage is hoisted in place and fixed, and mounting the opposite-pull hook ribs and the inner stirrups within the range of the part above the bearing platform surface after a concrete surface is roughened and cleaned. Compared with the prior art, centralized modular machining, manufacturing and mounting of steel bars are achieved, the reinforcing steel bar machining jig frame and the reinforcing steel bar end positioning frame are used for machining the bridge stand column reinforcing cage in a workshop, and the reinforcing steel barpositioning precision and machining efficiency are improved; and traditional scaffold erecting and formwork erecting procedures are combined, and scaffold-formwork integration is adopted.
一种桥梁立柱无支架施工方法，包括：立柱钢筋笼加工，通过钢筋笼胎架对立柱钢筋笼进行加工；立柱预埋位置的测定，将立柱外边线的方向线放样到承台模板上，并用细线拉出立柱中心轮廓，作为立柱预埋钢筋笼的基准线；立柱钢筋笼整体吊装，钢筋笼插入承台及承台面以上部分段的对拉钩筋和内箍筋不安装，待立柱钢筋笼吊装就位并固定后，绑扎插入承台的部分钢筋，承台面以上部分范围内的对拉钩筋和内箍筋待混凝土面凿毛完成、清洗干净后安装；与现有技术相比，钢筋的集中模块化加工、制作与安装，桥梁立柱钢筋笼在车间内利用钢筋加工胎架和钢筋端头定位架，提高钢筋定位精度和加工效率，将传统的搭设脚手架、立模工序合二为一，采用模架一体化。
