Description

Technical Field

[0001] The utility model relates to the technical field of steel templates, in particular to a steel template which is easy to assemble and fix. Background Art

[0002] Steel formwork is a common building material used for pouring and forming concrete. Steel formwork, also known as non-disassembly formwork, can replace wooden formwork, significantly reducing the pore water pressure and air bubble removal in concrete usually caused by traditional sealing formwork such as wood, plywood, or steel plates.

[0003] At present, when assembling steel formwork, bolts are generally used to assemble and fix the steel formwork. On-site operation is difficult and time-consuming, and a lot of time and labor costs are wasted. At the same time, the bolt connection method is not tight enough, and concrete can easily leak through the gaps between the formwork, which brings safety hazards to the construction of the house. At the same time, due to the lack of reinforcement and matching components between the steel formwork and concrete, the connection between the concrete and the formwork after pouring is not tight enough and the strength is low, so it needs to be improved.
