Steel box-concrete composite beam bridge deck slab formwork system and construction method
The invention discloses a steel box-concrete composite beam bridge deck slab formwork system and a construction method. The formwork system comprises a steel box beam bottom plate, the top face of the steel box beam bottom plate is connected with vertical steel box beam side webs and a steel box beam middle web, and a steel box beam top plate is arranged at the top of each steel box beam side web and the top of each steel box beam middle web; the steel box beam side webs on the two sides are provided with adjustable triangular support overhanging flange plate cantilever casting systems, and the cast-in-place bridge deck slab bottom flexible lossless clamping and opposite supporting bottom die supporting system is installed between the steel box beam middle web and the steel box beam side webs. The method comprises the steps of prefabricating, transporting and splicing the steel box beam segments, installing the adjustable triangular support, erecting the steel box beam and edge protection, installing the cast-in-place bridge deck, binding the steel bars, installing the embedded steel pipes, pouring and maintaining, removing the formwork and the support, and detaching the formwork and the support. The problems of complexity and safety of formwork erecting of the steel box-concrete composite beam bridge deck slab are effectively solved.
本发明公开了一种钢箱‑混凝土组合梁桥面板支模体系及施工方法，支模体系包括钢箱梁底板，钢箱梁底板顶面连接有竖直的钢箱梁侧腹板、钢箱梁中间腹板，每个钢箱梁侧腹板、钢箱梁中间腹板顶部有钢箱梁顶板，两侧的钢箱梁侧腹板安装有可调式三角支架悬挑翼缘板悬浇体系，钢箱梁中间腹板与钢箱梁侧腹板之间安装有现浇桥面板底部柔性无损夹固对撑底模支撑体系，方法包括钢箱梁节段预制运输以及拼装、安装可调式三角支架、架设钢箱梁和临边防护、安装现浇桥面板、绑扎钢筋、安装预埋钢管、浇筑养护、拆除模板及支架、拆除模板及支架。本发明有效解决了钢箱‑混凝土组合梁桥面板支模的复杂性、安全性的问题。
