Construction method for building steel inner cylinder chimney
The invention discloses a construction method, particularly discloses a construction method for building a steel inner cylinder chimney and belongs to the technical field of building construction processes of constructional engineering structures. The construction method for building the steel inner cylinder chimney is convenient to construct and operate and relatively low in construction cost. The construction method comprises the following steps that on the basis of a constructed concrete outer cylinder, a working platform and a lifting system are respectively mounted at two elevation positions which are not lower than 32 meters and not higher than 132 meters in the concrete outer cylinder; then, a lower-section steel inner cylinder chimney and an upper-section steel inner cylinder chimney are manufactured at the bottom in the concrete outer cylinder and on the working platform at the 32 m elevation position through the inverted installation method of sectional assembly and accumulative lifting, and finally, the upper-section steel inner cylinder chimney and the lower-section steel inner cylinder chimney are connected into a whole through an expansion joint, and the construction work of the steel inner cylinder chimney is completed.
本发明公开了一种施工方法，尤其是公开了一种用于建造钢内筒烟囱的施工方法，属建筑工程结构物建造施工工艺技术领域。提供一种施工操作方便，施工成本相对较低的用于建造钢内筒烟囱的施工方法。所述的施工方法以施工完成的混凝土外筒为基础，先在混凝土外筒内不低于32米和不高于132米的两个高程处分别安装工作平台以及提升系统，然后在混凝土外筒内的底部和32m高程处的工作平台上均分别采用分节组对、累积提升的倒装法制作下段钢内筒烟囱和上段钢内筒烟囱，最后通过膨胀节将上段钢内筒烟囱和下段钢内筒烟囱连接为一个整完成钢内筒烟囱的建造工作。
