Alternatively, use a gauging rod to accurately space them and install continuous temporary ties to secure the trusses. Temporarily brace the first truss back to the ground, plumb, straight and in the correct position.īrace each successive truss back to the first truss with TrussSpacers.
Prior to putting up trusses, make sure the wall frames below are adequately braced in and out of plane and stable.
Mitek truss stabilizers code#
They come from AS 4440 and the Code of Practice for Preventing Falls in Housing Construction produced by Safe Work Australia. Here is a brief summary of the main important points to remember. Preventing a roof collapse during erection is simply compulsory. Right from the first truss, each and every subsequent truss must also be safely secured before continuing.
Properly installed temporary bracing dramatically increases the stability of the erected trusses and provides workers with a stiff platform to work from. Roof trusses are typically installed at heights in excess of 2 m above ground which is an environment whereby a worker could sustain a serious injury from a fall. Storms and workers on the roof can easily push inadequately restrained roof trusses out of alignment, so it is very important that temporary bracing follows the requirements of AS 4440 to prevent this from happening. If they are installed in a crooked manner, they begin to lose strength and stiffness very quickly and the result will be a disappointing finish.īefore the roof and ceiling are laid, the trusses must be fully secured with adequate restraints and bracing so that they remain straight and true throughout the construction process and beyond. Trusses must be straight and plumb to be structurally strong. But why is temporary bracing so important, you ask? For two simple reasons:
