Mivan wedge pins are critical components in the Mivan aluminum formwork system, designed to secure and align formwork panels during concrete pouring. Below is a detailed breakdown of their features, specifications, and applications, synthesized from multiple sources:

• Primary Function: Mivan wedge pins (also called stub pins or locking pins) are used to interlock formwork panels (walls, slabs, columns) and ensure structural integrity during concrete casting. They prevent panel displacement under pressure, maintaining alignment and leak-proof joints 

• Design: Cylindrical pins with grooves or threads, paired with wedges for tightening. The wedge secures the pin in place, creating a rigid connection 

• Pin Body:

  • Material: Mild steel (common) or stainless steel (for corrosion resistance) 

  • Length: Standard sizes include 50 mm, 60 mm, and 70 mm, with some suppliers offering customized lengths 

  • Diameter: Typically 16–20 mm (e.g., 16x50 mm or 12x24V73) 

• Wedge:

  • Made of mild steel, galvanized for durability.

  • Acts as a locking mechanism to tighten the pin and eliminate gaps between panels 

• Load Capacity: Withstands up to 2–3 tons of concrete pressure 

• Surface Treatment: Hot-dipped galvanized, polished, or powder-coated to resist rust and corrosion 

• Packaging: Sold in bags (500–1,000 pieces per bag) or wooden boxes 

• Wall and Column Formwork: Aligns vertical panels for walls, elevator shafts, and columns 

• Slab and Beam Formwork: Secures horizontal panels for floors and beams 

• Specialized Use: Simplifies corner, radius, and laydown applications in complex structures 

1. Insert the pin through pre-drilled holes in overlapping formwork panels.

2. Drive the wedge into the pin’s groove using a hammer or lever to tighten the connection.

3. Attach a retaining clip (optional) to prevent dislodging during vibration 

4. After curing, remove the wedge and pin for reuse.

• Reusability: Can be reused 500–1,000 times with proper maintenance 

• Efficiency: Enables rapid assembly and disassembly, reducing labor time 

• Cost-Effective: Long lifespan lowers replacement costs 

• Safety: Minimizes formwork blowouts by maintaining even pressure distribution
