Turnbuckle Form Aligner

Turnbuckle Form Aligner is an adjustable brace that pushes and pulls concrete formwork into line. One end fixes to the form and the other to a stake or the ground, and turning the turnbuckle between them moves the form face until it is plumb and straight. Aligners are made to suit the forms they work with: request a quote with the fixing details, quantity and finish.

Function

Sets form faces to line

The brace moves a form face in or out and then holds it on line and plumb while the concrete is placed.

Construction

Turnbuckle between two ends

Left- and right-hand threads meet in a turnbuckle body. A bracket on one end fixes to the form, and a punched square leg on the other takes a stake.

Made to order

Matched to your forms

How it works

Turn to push, turn to pull

With both ends fixed, turning the turnbuckle one way lengthens the brace and pushes the form out; turning it the other way pulls it back. The crew checks the face with a level or string line, adjusts, and leaves the brace in place through the pour.

Common applications

Where it is used.

Application

Wall and footing forms

Wall and footing forms are braced along their length so the face stays straight as concrete rises.

Application

Kerb and road forms

Long runs of edge forms are trued to the string line before paving concrete goes in.

Application

Slab edge forms

Slab edges are held to line and level at each brace point along the perimeter.

Where are Turnbuckle Form Aligners placed along a form?

Turnbuckle Form Aligners are fixed at intervals along the form, with one end on the form or its waler and the other on a stake driven into the ground. The spacing follows the form system and the height of the pour. Each one is adjusted until the face reads true to the string line.
