Arch bridge encased concrete top plate formwork construction method and top plate formwork thereof
The invention relates to the technical field of steel skeleton arch bridge encased concrete construction, in particular to an arch bridge encased concrete top plate formwork construction method and a top plate formwork thereof. According to the construction method, a top plate inner formwork is suspended through a lifting tool to achieve respective splicing of a top plate inner formwork body section and a chamfering section, and support-free installation of the top plate inner formwork is achieved; the problems that a supporting frame slides and the limited space in the box is occupied are avoided, meanwhile, a construction platform is arranged at the bottom of the top plate inner mold body section, installation of the top plate formwork is facilitated, a passing channel is formed below the top plate inner mold body section, convenience is provided for construction of other structures in the arch box, a channel is provided for turnover use of the top plate formwork, and the construction efficiency is improved. The next section of top plate formwork can be installed without waiting for completion of current top plate construction, the construction efficiency is effectively improved, the top plate formwork is installed and formed through the construction method, the matching degree between the top plate formwork and the arch rib line type is high, and the line type quality of formed concrete can be guaranteed.
本发明涉及劲性骨架拱桥外包混凝土施工技术领域，特别涉及一种拱桥外包混凝土顶板模板施工方法及其顶板模板，该施工方法通过起重工具悬吊顶板内模实现顶板内模主体段和倒角段的分别拼装，实现顶板内模无支架安装，避免了支撑架滑移风险和占用箱内有限空间的问题，同时，通过在顶板内模主体段底部设置施工平台，方便顶板模板的安装，且在顶部内模主体段下方形成穿行通道，为拱箱内其他结构的施工提供了便利，为顶板模板的周转使用提供通道，使下一节段顶板模板勿需等待当前顶板施工完成即可进行安装，有效提高了施工效率，该顶板模板采用该施工方法安装成型，与拱肋线型匹配度较高，能够确保成型混凝土的线型质量。
