Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a circular silo plain concrete template device. Background Art

[0002] Silos are generally used to store loose granular or small pieces of raw materials or fuels, such as ore, coal, sand, cement, cereals, etc. The cross-section of the silo is generally circular. Plain concrete generally refers to concrete that is poured without any coating, tiling, stone or other materials. Plain concrete has the advantages of not requiring additional exterior wall painting, saving manpower and material resources, and returning to nature. Generally, circular silos, such as granaries, use plain concrete structures. In the prior art, the templates used for the construction of plain concrete silos include outer templates and inner templates, both of which are composed of multiple curved steel templates spliced ​​horizontally and vertically to form a cylindrical shape, and then plain concrete construction is carried out between the cylindrical outer template and the inner template.

[0003] The outer formwork and inner formwork generally use curved steel plates. When multiple curved steel plates are spliced ​​together, certain deformation and dislocation will occur in the process of splicing the formwork into a circle, resulting in poor sealing. When pouring concrete, part of the concrete may flow into the gap, affecting the outer wall quality and aesthetics of the plain concrete after molding. Utility Model Content
