Construction method for casting and prefabricating large-section bent cap wet joint based on suspended formwork
The invention provides a construction method for casting a prefabricated large-section bent cap wet joint based on a suspended formwork. The construction method comprises the steps that S1, a prefabricated bent cap is installed in place; s2, the splicing face of the prefabricated cover beam wet joint is treated; s3, a hanging bracket platform is installed; S4, a steel formwork is laid on the longitudinal distribution beam, and the steel formwork is made to be tightly attached to the bottom of the prefabricated cover beam for shaping; s5, wet joint concrete is poured, and a wet joint splicing surface is treated; s6, wet joint steel bars and corrugated pipes are installed, and prestress tensioning is adjusted; and S7, the side formworks are closed, concrete pouring is completed, and the hanging bracket platform is dismantled. According to the construction method, the recyclable hanging bracket is matched with the formwork hanging system of the shaped steel formwork for construction, the labor and material cost is greatly saved, the construction efficiency is improved, the safety risk of erecting a supporting system is avoided, and high economic benefits are achieved.
本发明提供一种基于吊模浇筑预制大截面盖梁湿接缝施工方法，包括：S1、将预制盖梁安装到位；S2、对预制盖梁湿接缝拼接面进行处理；S3、安装吊架平台：S4、在所述纵向分配梁上铺设钢模板，使钢模板紧贴预制盖梁底部，用于定型；S5、浇筑湿接缝混凝土，处理湿接缝拼接面；S6、安装湿接缝钢筋以及波纹管，调整预应力张拉；S7、封闭侧模，完成混凝土浇筑，拆除吊架平台。本发明采用可循环利用的吊架配合定型钢模板的吊模体系施工，较大的节约了人工、材料的成本，提升了施工效率，避免了支撑体系搭设的安全风险，具有较高的经济效益。
