Mivan Tie Rod

About Mivan Tie Rod

What is a Tie Rod and Why is it Used?

In civil engineering and high-rise construction, a Formwork Tie Rod (also known as a concrete thread bar or high-tensile tie rod) is a rugged steel bar featuring a continuous, coarse hot-rolled or cold-rolled thread pattern.

Why it is used:

• Absorbs Outward Pressure: It acts as a heavy-duty structural anchor that holds opposing shuttering panels firmly together, counteracting the massive hydrostatic forces of freshly poured concrete.

• Ensures Perfect Wall Thickness: It prevents the panels from expanding outward, keeping concrete wall dimensions accurate down to the millimeter.

• Maximizes Worksite Safety: It drastically minimizes the risk of dangerous formwork blowouts during high-volume mechanical concrete pumping and internal vibration.

Technical Classifications of Tie Rods

Tie rods are categorized based on their production engineering and physical strength profiles:

• Hot-Rolled Tie Rods: Forged at high temperatures, these bars feature a coarse, broken thread design. They boast extreme load capacity, incredible elasticity, and are self-cleaningmeaning hardened concrete residue flakes off easily.

• Cold-Rolled Tie Rods: Threaded using precision cold-rolling machinery. These bars have a finer thread pitch and offer a highly cost-effective, budget-friendly alternative for standard residential developments.

• Standard Industrial Sizes: Universally supplied in 15/17 mm diameters (15mm inner / 17mm outer thread) for everyday building walls, and heavy-duty 20/22 mm formats for massive structural projects.

Core Infrastructure Applications

• High-Rise Shear Walls & Core Walls: Ensuring alignment in commercial and residential tower shafts.

• Bridge Piers & Flyover Pillars: Securing massive concrete setups for structural highway projects.

• Water Retaining Structures & Dams: Used alongside specialized water barrier nuts to prevent moisture seepage.

• Aluminum Shuttering Systems: Integrating seamlessly into modern modular Mivan formwork systems.

Indian Testing Standards (IS Codes)

To guarantee complete safety on-site, Surya Engineering products are precision-tested to match top Bureau of Indian Standards (BIS) parameters:

• IS 1786: Dictates the proof stress, elongation properties, and high-tensile material strength.

• IS 2062: Governs structural steel grades to make sure the core metal handles immense high-tonnage tension without snapping.

Key Advantages of Surya Engineering Tie Rods

• High Load Capacity: Safely withstands working breaking loads ranging from 95 kN to over 145 kN.

• Maximum Reusability: Built from high-durability carbon steel, our rods can be reused across hundreds of concrete pouring cycles.

• Zero On-Site Waste: The continuous thread allows workers to cut the bars down to any custom wall thickness directly on the job site.
