Description

Technical Field

[0002] Precast formwork is a modern building construction material that is widely used on construction sites. It is made on-site on a production line, including a steel skeleton and concrete, and can be used to support and strengthen concrete structures. The characteristics of this precast component are that it has high strength and excellent durability, and can be made into different sizes and shapes to meet different engineering needs.

The use of a vibrating rod to vibrate section by section greatly increases the workload of construction workers, and it is impossible to intuitively detect whether the pouring voids have been flattened by the vibrating rod, which easily leads to a situation where there are many voids in the cement pouring of precast formwork.
