[0015] 1. Several auxiliary plate bodies are hinged around the lower plate through the support plate. The auxiliary plate bodies can be used for work such as mold removal and watering of the shaft wall, while the lower plate of the hanging plate can be used for operations such as tying steel bars, stabilizing the mold, pouring concrete, etc., which solves the problem of narrow working platform in the shaft and provides a more spacious and safe working space for operators;

[0016] 2. Provide better protection for multi-layer workers and reduce the risk of accidents. For example, in the construction of the inner wall of the freezing shaft, adding auxiliary plates around the upper and lower plates of the hanging plate can solve the safety problems of multi-layer operations in reverse mold construction;

[0017] 3. The setting of the auxiliary plate can place some construction equipment or tools, which further optimizes the construction conditions, enhances the stability of the entire hanging plate system, reduces problems such as shaking and imbalance, and ensures the smooth progress of construction.
