Composite steel sleeve type chimney reinforcing structure and construction method thereof
The invention relates to a composite steel sleeve type chimney reinforcing structure and a construction method thereof, and relates to the technical field of reinforcement and reconstruction of existing concrete chimneys. The steel sleeve can be divided into a plurality of sections in the vertical direction, each section can be divided into a plurality of fragments in the annular shape, a lower-section annular flange and an upper-section annular flange are arranged at the upper end and the lower end of each section of the steel sleeve, and a left-side vertical flange and a right-side vertical flange are arranged on the left side and the right side of each fragment of the steel sleeve. The adopted steel sleeve is used for replacing a traditional concrete formwork in the construction stage and used for replacing steel bars after being formed, the fabricated construction platform is adopted for assembling the steel sleeve and pouring the concrete composite layer, a special construction platform and a scaffold do not need to be built at high altitude, and high-altitude formworks and binding steel bars are not needed; the problem that a high-altitude formwork and a construction platform need to be built in a traditional section increasing reinforcing method is solved, and the safety, the construction efficiency and the economic benefits of a chimney reinforcing project are remarkably improved.
本发明涉及一种复合钢套筒式烟囱加固结构及其施工方法，涉及对既有混凝土烟囱的加固改造技术领域，其包括钢套筒、混凝土复合层；钢套筒沿竖向可设为多个分段，每个分段沿环形可设为多个分片，钢套筒每个分段的上下端设有下节环向法兰和上节环向法兰，钢套筒每个分片的左右侧设有左侧竖向法兰和右侧竖向法兰。本发明所采用钢套筒在施工阶段用于代替传统的混凝土模板，成型后用于代替钢筋，并采用装配式施工平台进行钢套筒的组装和混凝土复合层的浇筑，无需高空搭建专门的施工平台及脚手架、无需高空模板及绑扎钢筋，不仅解决了传统增大截面加固法所需的高空模板与施工平台搭建难题，还显著提升了烟囱加固工程的安全性、施工效率和经济效益。
