Description

Cone shell formwork system with large slope on top of silo

technical field

The utility model relates to a large-slope cone shell formwork system at the top of a silo.

Background technique

With the development of the construction industry, especially the increasing growth of industrial buildings, silo buildings are relatively common buildings in the coal mining industry. Cone shells are generally constructed on the top of silos for collecting materials. The slope of the conical shell of some cylinders is relatively large, and the inclination slope reaches more than 50 degrees. Before pouring the conical shell with such a large slope, it is necessary to build a large-diameter conical shell formwork system. When building the formwork system according to the existing technology Firstly, the bottom formwork is set up and poured. After the poured concrete is solidified, the bottom formwork is removed, and then the second floor formwork is erected. Only by re-cutting and assembling the lower formwork can it meet the erection requirements of the second-layer formwork. Similarly, when continuing to build up, there is the same new problem of formwork cutting and assembly, which brings a large workload of on-site formwork assembly and large formwork consumption. The problem.
