Construction method of mass concrete based on roof foundation bearing platform
The invention discloses a large-volume concrete construction method based on a roof foundation platform, which comprises the following steps of: according to the design of the roof foundation platform, measuring, setting out and calibrating the elevation; after construction measurement work is done according to the construction drawing, earth excavation is carried out, and then soil cleaning and leveling work is carried out; a bearing platform concrete cushion layer is poured, a combined steel formwork line is laid, then the steel formworks are assembled, and the steel formworks are corrected; reinforcing steel bar supports and reinforcing steel bar binding are carried out, the reinforcing steel bars are erected in the steel formworks, and the method for erecting the reinforcing steel bar supports and binding the reinforcing steel bars further comprises the steps that bearing platform bottom bars are installed; i-shaped steel stand columns are welded; welding middle horizontal supporting channel steel; middle reinforcing steel bars are installed; top horizontal supporting channel steel is welded; surface layer steel bars are installed; carrying out concrete pouring on the bearing platform; and after the concrete reaches the specified strength, the steel formwork is dismantled, and construction of the mass concrete is completed. The combined steel formwork is adopted, deformation damage of the foundation platform can be reduced, the foundation platform is more regular after construction, and the construction quality is greatly improved.
本发明公开了一种基于屋盖基础承台的大体积混凝土的施工方法，包括以下步骤：根据屋盖基础承台的设计，测量放线并定标高；根据施工图做好施工测量工作后，进行土方开挖，然后进行清土和平整工作；浇筑承台混凝土垫层，放组合钢模板线，再组装钢模板，并校正钢模板；钢筋支架及钢筋绑扎，钢筋搭设于钢模板内部，钢筋支架搭设及钢筋绑扎的方法进一步为：承台底筋安装；工字钢立柱焊接；中部水平支撑槽钢焊接；中部钢筋安装；顶部水平支撑槽钢焊接；面层钢筋安装；承台混凝土浇筑；待混凝土达到规定强度后，拆除钢模板，完成大体积混凝土的施工。本发明采用了组合钢模板，能够减少基础承台的变形损伤，使得施工后更加规整，大大提升了施工质量。
