The reasons for the deformation of building formwork include:
1. The assembly of small steel formwork is not set as required, resulting in poor overall performance of the building
2. The foundation on which the formwork is placed is not firm, the flat plate is not placed, and the foundation settlement is caused by poor waterproof measures
3. The wooden building formwork or plywood are used for construction, and the concrete is not poured in time after acceptance, and the surface is deformed due to long-term sunshine and rain.
4. The support spacing is too large, and the rigidity of steel plate is poor
5. The pouring speed of wall and column concrete is too fast, the one-time pouring height is too high, and the vibration is too high
