What Is a Formwork Tie Rod? Components and Uses

A formwork tie rod connects opposing formwork faces and helps maintain the intended spacing during concrete placement. Tie rods are commonly used in wall and column formwork.

Main Components

A tie-rod system can include the threaded rod, nut, bearing plate, sleeve, plug and special connection components depending on the formwork arrangement.

Rod, Nut and Bearing Plate

The rod forms the tensile connection, the nut provides clamping and the bearing plate spreads the bearing force over a larger surface.

See Tie Rod, Nut and Bearing Plate: How They Work.

Water-Stop Tie-Rod Details

Water-retaining structures can require dedicated water-stop components, sleeves and plugs rather than a standard removable tie passage.

See Water-Stop Tie Rod, Pipe and Plug.

T and L Tie Rods

T and L tie rods are special connection components with different geometries from a standard straight threaded tie rod.
