Formwork Tie Rods – Threaded Bar Supply for Various Construction Projects

Formwork tie rods play a crucial role in the construction process by providing stability and support to formwork structures, allowing concrete to be shaped and set properly in various construction projects.
Formwork Tie Rod Types

What is Formwork Tie Rod?

A formwork tie rod is a crucial component used in construction to support and secure the formwork, which is the temporary mold or structure used to shape and support concrete until it hardens. In simpler terms, it helps in creating the desired shape and structure for concrete during construction. It is a tool used in the process of formwork fabrication to position and secure the formwork.

It typically consists of a rod body, rod seat, springs, and other components. The function of the formwork tie rod is crucial as it ensures the accuracy and quality of formwork fabrication.

Dimensions: The length of formwork tie rods is determined based on practical needs, and it affects the efficiency and precision of formwork fabrication. Generally, the length of the rod ranges from 500 to 2000 mm and can be customized as required. Additionally, the diameter of the formwork tie rod influences its performance, with common diameters being 8mm and 10mm.

Formwork Tie Rod Quality Certification

Formwork Tie Rod Classification:

Common materials for formwork tie rods include aluminum alloy and steel. Aluminum alloy is lightweight, easy to handle, while steel is heavier, offering high strength and suitability for large-scale formwork fabrication. The surface of formwork tie rods is often treated through processes like oxidation or coating. Different surface treatments enhance corrosion resistance and improve the appearance quality of the formwork tie rod.

Formwork tie rods can be classified into two main types based on their design:

Shear Tie Rods:

  • These tie rods are designed to resist the horizontal forces that act parallel to the surface of the formwork.
  • They help prevent the concrete from spreading or shifting sideways while it is being poured and as it sets.

Waler Tie Rods:

  • Waler tie rods are used to resist vertical forces that act perpendicular to the surface of the formwork.
  • They provide additional support to keep the formwork stable and prevent it from collapsing under the weight of the concrete.

Formwork Tie Rod Features:

  • Threaded Design:
    Most formwork tie rods have a threaded design, allowing them to be easily connected and adjusted to the required length. This threaded feature makes it convenient for construction workers to assemble and disassemble the formwork quickly.
  • High Strength:
    Formwork tie rods are made from materials with high strength, such as steel, to ensure they can withstand the loads and pressures exerted during the concrete pouring and setting process.
  • Versatility:
    These rods are versatile and can be used in various types of formwork, such as wall forms, slab forms, and column forms, making them essential in different construction scenarios.

Formwork Tie Rod Applications:

Formwork tie rods find widespread applications, from home renovations to large-scale construction projects. Therefore, different specifications and types of formwork tie rods are needed for various applications. Common specifications include φ10, φ12, φ14, and types include single rod, double rod, and triple rod.Formwork tie rods find applications in a variety of construction projects, including:

Building Construction:Used to create the formwork for walls, columns, and slabs in buildings.
Bridge Construction:Employed in the construction of bridge structures to shape and support concrete elements.
Tunnel Construction:Utilized in the creation of formwork for tunnels, ensuring the concrete maintains the desired shape during construction.

Precautions of Formwork Tie Rod

Formwork tie rods play a crucial role in the construction process by providing stability and support to formwork structures, it is a type of structural tie rod which allowing concrete to be shaped and set properly in various construction projects.

  • Select formwork tie rods with specifications, types, and dimensions that suit your needs.
  • Store them in a dry, well-ventilated place, avoiding direct sunlight during storage.
  • When in use, adhere to operational guidelines, avoid excessive force to prevent issues such as breakage or deformation of the formwork.
