Sacrificial Tie Rod: Definition & Purpose

A sacrificial tie rod (or tie bar) is a temporary tensioning device used in concrete formwork systems to hold opposing formwork panels (e.g., walls, columns) together during concrete pouring. It is designed to be partially or fully embedded in concrete and often sacrificed (left in place or cut off) after demolding, unlike reusable tie rods.

⚙️ Key Features & Design

1. Material:

   • Carbon Steel (common) with epoxy coating or galvanization for corrosion resistance.

   • Threaded Ends: Allow attachment to formwork via nuts and washers.

2. Sacrificial Element:

   • The rod is cut flush with the concrete surface after curing, leaving the inner segment embedded.

   • Alternatively, break-back designs snap off at a pre-scored point.

3. Load Capacity:

   • Withstands lateral pressure of wet concrete (typically 20–60 kN/m²).

4. Sizes:

   • Diameters: 12mm–20mm; Lengths: Custom (based on formwork thickness).

🏗️ Applications

• Wall Formwork: Prevents bulging under concrete pressure.

• Column Formwork: Ensures uniform cross-section.

• Tunnels & Retaining Walls: High-stress environments requiring robust bracing.
