Arched bridge bottom plate forming construction method
The invention discloses an arched bridge bottom plate forming construction method, and relates to the technical field of bridge construction, the arched bridge bottom plate forming construction method comprises a formwork used for bridge bottom forming and a supporting formwork used for supporting the formwork, and the construction method comprises the following steps that a box girder bottom plate is paid off and inspected; mounting a supporting formwork; after a supporting formwork is erected, measuring, leveling and positioning the top elevation of a jacking, adjusting the jacking to reach the elevation, sequentially laying transverse I-shaped steel, longitudinally laying battens, fixing the battens and the I-shaped steel by adopting iron wires according to drawing requirements, and after the battens are laid, laying a film-coated bamboo plywood special for a bridge as a bottom formwork; molding a template; the problem that different types of products cannot be used universally can be solved; and the panel is still made of non-standard customized large blocks, the delivery state is still large assembly shipment, and the problems that due to pure modular design and preparation, the number of assembly workers is large, the number of assembly seams is too large, and the assembly quality is difficult to guarantee are solved.
本发明公开一种拱形桥底板成型施工方法，涉及桥梁施工技术领域，包括设用于桥底成型的模板和用于对模板进行支撑的支撑模架，施工方法包括以下步骤：箱梁底板放线、验线；支撑模架安装；模板铺设：待支撑模架搭设完成后，测量抄平，定位顶托顶标高，调节顶托达到标高之后，按图纸要求依次铺设横向工字钢，纵向再铺设木方，木方与工字钢采用铁丝固定，木方铺设完成后，铺设桥梁专用覆膜竹胶板作为底模；模板成型；可以解决不同类型的产品之间无法通用的问题；而面板仍然采用非标定制的大块化，交货状态仍然是大块化装配体出货，避免了纯模块化设计制备，而导致的拼装用工多，拼装缝太多，拼装质量难以保证的问题。
