Factory Supplied Concrete Formwork Aluminum Wall Forms Flat Tie for Building Material

It is a critical load-bearing component within modern aluminum formwork systems. It is a high-strength steel tie rod that passes horizontally through the concrete wall cavity, connecting the two opposing aluminum formwork panels. Externally, it interfaces with the scaffolding or waling system to transfer the immense lateral pressure of wet concrete into the support structure, ensuring wall thickness accuracy and preventing formwork blowout.

For an accurate quote and support, please provide: Wall design data (height, pour rate) or calculated concrete pressure. Your formwork system brand and waling profile details. Required wall thickness and target tie spacing. Project quantity estimate (linear meters of wall or total ties).

A complete assembly typically includes: Tie Rod (High-Tensile Bar): The core load-bearing element, usually hot-dip galvanized. Internal Cone (or She-Bolt Assembly): A plastic or steel cone on each end inside the concrete, creating a recess for patching. External Tie Bracket/Wedge: Connects the protruding rod end to the aluminum waler (strongback). Scaffolding Node Connector (in some systems): Allows the external end to directly connect to the aluminum scaffolding frame for integrated support. Nu

Material: High-Tensile Alloy Steel, typically Grade 10.9 (minimum tensile strength 1040 MPa) or equivalent to SAE Grade 8. Diameter: Common sizes are 17mm, 19mm, and 21mm, correlating to specific safe working loads (e.g., 55kN, 75kN, 95kN). Finish: Hot-Dip Galvanizing (HDG) to ASTM A153 for maximum corrosion resistance is standard. Stainless Steel options are available for specialized projects.

This is a structural calculation based on: Design Concrete Pressure: Calculated from pour rate, concrete density, temperature, and wall height (per standards like ACI 347 or CIRIA Report 108). Waler Spacing and Capacity. Required Safety Factor (typically 2.0). We provide technical data sheets with certified load capacities (SWL). Our engineering team can assist with layout design based on your project parameters.
