Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical silo construction, and more specifically, particularly relates to a construction frame which is easy to assemble. Background Art

[0002] After the vertical cylindrical silo wall of the concrete silo is poured, the silo roof is added on top of the silo wall to form a complete silo. In the prior art, the silo roof is generally constructed by setting up a full-height scaffolding formwork inside the silo during the concrete pouring construction process. The full-height scaffolding requires a large amount of steel pipes, fasteners and other materials, which are combined and connected in sequence from bottom to top. The workload is large, the assembly time is long, and the work efficiency is low; the internal space of the silo is small, and the installation and connection operations are inconvenient; the cylindrical silo wall usually only has a few small holes reserved at locations such as doors, windows, and inspection holes, and there is no large material transportation channel. Although the scaffolding materials can be hoisted and transported by a tower crane before the silo roof is poured, which reduces part of the workload, it is more difficult to dismantle and remove the scaffolding after the silo roof is poured, and it is also easy to cause material damage and scrapping, increasing the construction cost investment.
