SPECIFICATION

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.
