Temporary bracing is meant to hold the trusses true to line, dimensions, and plumb during the erection of the roof. This will also hold the trusses in a stable condition until permanent bracing’s are in place.
It is important for a multitude of reasons, including:
- Helping to withstand the gravity forces of its own weight
- Resist wind loads during construction
- Support temporary construction dead loads such as the weight of sheathing and roofing materials
- Keeping the trusses plumb
- Assuring the correct truss spacing
With this bracing, there are two common styles to choose from.
- Start with the gable-end truss: For this technique, start by sheathing the gable-end truss on the ground and lifting it first. The gable-end truss can unfortunately be difficult to brace without the braces interfering with the second truss. Though, on a one-story building, it can be braced to stakes driven in the ground.
- Start several trusses in: For this technique, start the first truss 8- to 12-feet in from the gable end and brace it to the deck. Working from the bracing end, fill in the open 8- to12-feet section last, after you have permanently braced the rest of the trusses.
When thinking of temporary bracing, it’s important to remember how our other services can help this. For instance, using a crane delivery can provide you with an easy solution to a temporary brace. The crane truck is able to hold your trusses vertically while you nail the bottom chord to the plates.
Temporary bracing can be the difference between a smooth and rocky set-up. It can also help to reduce bending, breaking, and fracturing of the trusses.
