Circular Column Formwork

Purpose: Designed to construct round concrete columns with sturdy, reusable formwork that withstands concrete pressure during pouring and curing.

Design: Composed of curved panels or shells (usually steel, aluminum, or high-grade plywood) that form a cylindrical shape when assembled. Panels are secured with clamps, bolts, or locks to maintain their shape.

Material: Made from high-strength steel, aluminum, or plywood, often galvanized or coated for corrosion resistance.

Surface Finish: Smooth interior for seamless concrete finishes, minimizing post-pour treatment.

Components of the Circular Column Formwork System:

• Curved Panels/Shells: Form the circular shape; made from steel, aluminum, or plywood with a smooth surface.
• Connecting Clamps/Bolts: Secure panels together, simplifying assembly and disassembly.
• Adjustable Rings or Belts: Hold panels in place, resisting concrete pressure.
• Base Plates: Provide a stable foundation and even load distribution.
• Top Collar (Optional): Ensures a clean edge at the top and controls concrete flow during pouring.

Technical Specifications:

• Material: Steel (galvanized/powder-coated), aluminum, or moisture-resistant plywood.
• Diameter: Standard range from 200 mm to 1200 mm, with custom sizes available.
• Height: Modular sections from 0.5 m to 3 m, stackable for desired height.
• Load Capacity: Rated for concrete pressures up to 80 kN/m² or higher.
• Surface Finish: Smooth inner surface for a high-quality concrete finish.

Advantages:

• Smooth Finish: Reduces the need for additional surface treatment.
• Adjustable: Modular for varying column heights and diameters.
• High Strength: Resists lateral pressure from wet concrete.
• Ease of Use: Quick assembly and disassembly, suitable for multiple uses.
• Reusable: Durable materials allow for repeated use, making it cost-effective.

Applications:

• Round Concrete Columns: Ideal for circular columns in buildings, bridges, and infrastructure.
• Curved Structural Elements: Suitable for other circular or curved concrete forms in architectural projects.
