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:

1. Purpose and Design

• 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 

2. Key Components

• 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 

3. Technical Specifications

• 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 

4. Applications

• 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 

5. Installation Process

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.

6. Advantages

• 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

A Formwork Waller Clamp is a specialized mechanical device used in construction to securely fasten formwork panels during concrete pouring. Here's a detailed breakdown:

Definition & Purpose

• Primary Function: To hold together formwork panels (typically made of plywood, steel, or aluminum) that create molds for casting concrete walls, columns, or foundations.

• Key Role: Ensures formwork remains aligned and rigid under the pressure of wet concrete, preventing leaks or structural failures.

Design & Components

• Material: Constructed from high-strength, galvanized steel for durability and corrosion resistance.

• Mechanism: Features an adjustable clamping mechanism, often a wedge, lever, or threaded rod, allowing quick tightening/loosening.

• Components:

  • Jaws/Clamping Arms: Grip formwork edges.

  • Adjustment Tool: A handle or lever for applying pressure.

  • Locking Device: Such as a pin or wedge to secure the clamp in place.

Applications

• Used in vertical concrete structures like walls, elevator shafts, and retaining walls.

• Compatible with various formwork systems (e.g., modular or traditional timber).

• Available in multiple sizes to accommodate different panel thicknesses and load requirements.

Advantages

• Efficiency: Enables rapid assembly/disassembly of formwork, reducing labor time.

• Reusability: Durable design allows repeated use across projects.

• Safety: Minimizes risk of formwork blowouts by maintaining even pressure distribution.

• Cost-Effective: Longevity reduces replacement costs.

Safety & Best Practices

• Ensure clamps are rated for the expected concrete pressure.

• Inspect for wear, corrosion, or damage before use.

• Clean after use to prevent concrete buildup affecting performance.

Brand Context

• While "Waller" may refer to clamps by Waller Systems (a known formwork supplier), the term is often used generically for similar clamps in the industry.

Why It Matters

Proper use of Waller Clamps ensures precise, high-quality concrete surfaces and structural integrity, making them indispensable in modern construction projects. Their reliability and adaptability make them a staple in both small-scale and large-scale concrete work.
