Prefabricated reinforced concrete protective layer casing pipe method pier column construction technology and equipment
The invention relates to the field of reinforced concrete pier column construction, in particular to a prefabricated reinforced concrete protective layer casing method pier column construction technology and equipment. According to the pier column construction technology adopting the prefabricated reinforced concrete protective layer casing pipe method, firstly, a pier column steel bar protective layer casing pipe is prefabricated and formed, then the pier column steel bar protective layer casing pipe is installed at the design position of a pier column, and the pier column construction technology is repeatedly installed and poured through the procedures of vertical steel bar connection, annular steel bar and vertical main steel bar welding, center concrete pouring and the like. The construction technology is suitable for the reinforced concrete pier column with the circular section, and the diameter range is 1-2 m. The equipment for prefabricating the reinforced concrete protective layer sleeve comprises an outer mold, a modular inner mold, a bottom plate, a top mold and other auxiliary parts. The integral pouring process of the concrete filled steel tube pier column and the cylindrical pier column is integrated, the characteristics of corrosion resistance, low cost and consistent appearance of a concrete protection layer are reserved, the problem that the prefabricated pier column is difficult to hoist is solved, the operation efficiency is improved through design, and standardized popularization is facilitated.
本发明涉及钢筋混凝土墩柱施工领域，具体地说是一种预制钢筋混凝土保护层套管法墩柱施工工艺及设备。预制钢筋混凝土保护层套管法墩柱施工工艺是先把墩柱钢筋保护层套管预制成型，再安装到墩柱设计位置，经过竖向钢筋连接、环形钢筋与竖向主筋焊接、浇筑中心混凝土等工序，反复进行安装和浇筑的墩柱施工工艺。本施工工艺适合圆形截面的钢筋混凝土墩柱，直径范围在1～2m。预制钢筋混凝土保护层套管设备包括外模、模块式内模、底板、顶模和其他辅助部件。本发明综合了钢管混凝土墩柱和圆柱形墩柱整体浇筑工艺，保留混凝土保护层耐腐蚀、低成本、外观一致的特点，解决了预制墩柱吊装困难的问题，设计提高作业效率、利于标准化推广。
