Construction method of T-beam flange cross slope adjustable movable formwork
The invention relates to the technical field of bridge section construction and particularly relates to a T-beam flange cross slope adjustable movable formwork construction method. The method comprises the following steps that firstly, a supporting system is designed, a side span cast-in-place section and a closure section are subjected to a two-time pouring forming process, a side span is poured firstly, and a hanging basket is adopted as a construction support for construction; secondly, the hanging basket is constructed in a walking mode, and after the last cantilever section is poured and prestress tensioning construction is completed, an operation platform at a front cross beam at the bottom of the hanging basket is dismantled; thirdly, beam section construction is conducted, and square timber and thick bamboo plywood are adopted for a pier top bottom die to form a bottom die system; the side mold adopts a hanging basket side shaping steel mold; after binding of beam body bottom plates and wall body steel bars and installation of prestressed pipelines are completed, an inner mold is started to be assembled; and fourthly, counterweight construction is conducted, the needed counterweight weight is obtained according to a moment balance formula, and stress balance of the two ends of the T-shaped structure is kept in the ballasting construction. By means of the method, a problem that in the bridge construction process in winter, mounting and dismounting risks are caused by a traditional bracket is solved.
本发明涉及桥梁节段施工技术领域，具体涉及一种T梁翼缘横坡可调节式活动模板施工方法，包括以下步骤：步骤一、支撑体系设计，边跨现浇段与合龙段采用两次浇筑成型工艺，先浇筑边跨，采用挂篮做施工支架进行施工；步骤二、挂篮走行施工，在浇筑完最后一个悬臂节段后，预应力张拉施工完成后拆除挂篮底部前横梁处作业平台；步骤三、梁段施工，墩顶底模采用方木和厚竹胶板组成底模系统；侧模采用挂篮侧面定型钢模；梁体底板及墙身钢筋绑扎及预应力管道安装完毕后开始拼装内模；步骤四、配重施工，根据力矩平衡公式得出所需配重重量，压重施工中保持T构两端受力平衡。通过该方法解决了冬季桥梁施工过程中，因传统托架安装拆卸风险问题。
