Plastic formwork panel combine with steel frame

Key technical points:
1. Connection design
The plastic template needs to be fixed to the steel frame through buckles, bolts, or welding to ensure tight joints and prevent leakage of grout.
2. Temperature adaptability
Plastic may soften at high temperatures, so it is necessary to choose high-temperature resistant modified materials (such as PP, PVC reinforced) and avoid direct sunlight exposure.
3. Strengthen support
The steel frame should be designed with spacing based on the lateral pressure of the concrete, supplemented by steel back ribs or tension bolts to prevent mold expansion.
4. Selection of release agent
Use water-based release agents to avoid corrosion of the plastic surface and extend the lifespan of the template.
Matters needing attention:
Cost balance: The initial investment is relatively high, suitable for projects with high turnover times, and long-term benefits need to be comprehensively evaluated.
Design adaptability: Template dimensions need to be customized according to engineering requirements, and matching holes need to be reserved for the steel frame.
Maintenance: Clean the concrete residue promptly after use to avoid scratching the plastic surface with sharp objects.
