Slip form lifting system for building cast-in-place concrete chimney

SHANG XUEGANG / YUAN CHUNYANG

The invention discloses a slip form lifting system for building a cast-in-place concrete chimney, and belongs to the technical field of design and manufacturing of construction engineering structure building process equipment. The slip form lifting system for building the cast-in-place concrete chimney is relatively simple in structure, the construction efficiency is obviously improved, and the use cost is obviously reduced. The slip form lifting system comprises a supporting mechanism, a connecting assembly and a lifting mechanism, the lifting mechanism is arranged on the supporting mechanism through the connecting assembly, and the supporting mechanism is arranged on the top of a bound next chimney steel bar needing concrete pouring. The upper end of the cylindrical ultra-thin steel plate inner formwork and the upper end of the cylindrical ultra-thin steel plate outer formwork are connected with the lifting mechanism through connecting assemblies correspondingly. In the formwork lifting process, the cylindrical ultra-thin steel plate inner formwork and the cylindrical ultra-thin steel plate outer formwork which are separated from the concrete chimney where pouring is completed are lifted to the specified positions through the lifting mechanism under the cooperation of the supporting mechanism and the connecting assembly.

本发明公开了一种用于建造现浇混凝土烟囱的滑模提升系统，属于建筑工程结构物建造工艺装备设计制造技术领域。提供一种结构相对较为简单，施工效率显著提高，使用成本明显降低的用于建造现浇混凝土烟囱的滑模提升系统。所述的滑模提升系统包括支撑机构、连接组件和提升机构，提升机构通过连接组件布置在支撑机构上，支撑机构布置在绑扎完成的需要浇筑混凝土的下一带烟囱钢筋的项部，圆筒状超薄钢板内模板的上端和圆筒状超薄钢板外模板的上端分别通过连接组件与提升机构连接；模板提升过程中，与上带浇筑完成的混凝土烟囱脱离的圆筒状超薄钢板内模板和圆筒状超薄钢板外模板通过提升机构在支撑机构和连接组件的配合下提升至规定的位置。
