China Manufacturer Concrete Construction Formwork Column Adjustable Square Column Clamp

A Square Column Shuttering Clamp, commonly called a Column Ring Clamp or Column Formwork Clamp, is a specialized, adjustable steel clamp designed specifically to secure the four-sided formwork (shuttering) for square or rectangular concrete columns. It applies uniform, high-pressure clamping force on all four sides simultaneously to withstand the lateral pressure of wet concrete, ensuring precise dimensional accuracy and preventing bulging or misalignment.

High Precision & Accuracy: Ensures perfectly square/rectangular columns with consistent dimensions and sharp, clean corners. Rapid Assembly & Stripping: The modular, single-unit design is significantly faster to install and remove than assembling individual walers and tie rods for each column. High Reusability & Durability: Made from heavy-duty steel, it can be reused hundreds of times across projects. Labor & Cost Efficiency: Reduces labor time and eliminates the need for numerous loose compone

Our clamps are engineered for maximum strength and longevity: Main Frame: High-Tensile Carbon Steel (Q345B/S355JR). Adjustment Mechanism: Grade 8.8 Steel Threaded Rods and Forged Steel Wedges or Lever Handles. Pressure Points/Heads: Hardened Steel for wear resistance at contact points with the formwork. Standard Finish: Hot-Dip Galvanized (HDG) for superior corrosion resistance in outdoor site conditions. Alternative: Electro-galvanized or painted finishes available.

We offer a versatile range to cover common and large column sizes: Adjustable Range: Our standard models typically adjust to fit columns from 150x150mm (6'x6') up to 1200x1200mm (48'x48') and beyond. Fixed Sizes: Also available for high-volume projects requiring a specific, repetitive column size. Custom Sizes: We can design and manufacture clamps for any specific square or rectangular dimension upon request.

We offer two primary adjustment systems for different user preferences: Wedge & Pin System (Most Common): Place the clamp frame around the assembled column formwork. Insert the steel pin through aligned holes in the overlapping clamp arms. Drive the tapered steel wedge firmly with a hammer to apply and lock the precise tension. Threaded Screw System: Position the clamp. Turn the four corner screw mechanisms evenly with a wrench to achieve uniform pressure on all sides. Both systems provide excel
