Customised size steel frame use PVC formwork:
The application of combining PVC formwork panel with steel frames (such as building formwork systems) is a modern construction technology that combines the lightweight and corrosion resistance of plastic materials with the structural strength of steel frames, and has significant advantages in concrete pouring projects
Advantages:
1. Lightweight and convenient
PVC Formwork panel are lightweight (about 1/3~1/2 of steel templates), easy to transport and install, and reduce labor requirements; The steel frame provides rigid support to ensure overall stability.
2. High turnover and durability.
PVC Formwork panel templates are corrosion-resistant, acid and alkali resistant, not easily deformed, and can be reused more than 50-100 times; Steel frame reinforced structure extends service life.
3. High construction efficiency.
Modular design, flexible assembly, suitable for complex shapes (such as curved walls, irregular columns), precise positioning of steel frames, and improved pouring accuracy.
4. Excellent surface quality.
After demolding the plastic template, the concrete surface becomes smooth, reducing the need for later plastering processes and saving costs.
5. Environmental Protection and Economy.
Reduce wood consumption and recycle plastic; The long-term usage cost is lower than that of wooden formwork and close to that of steel formwork.
Typical application scenarios:
1. Building walls and floors
Steel frame as the main keel and plastic formwork as the panel are suitable for rapid construction of high-rise buildings.
2. Bridge piers and tunnels
Resistant to humid environments, supported by steel frames for compressive strength, suitable for pouring large volumes of concrete.
3. Production of prefabricated components
Used for factory prefabricated stairs and wall panels, combined with steel frames to ensure dimensional accuracy.
