Using Supporting Roof Bracing Already In Place

I have a client who wants a deck built approximately 10 off the ground with a roof.

Using supporting roof bracing already in place.

To hold them up until the decking of the roof is placed on top a 12 foot 1 inch by 4 inch piece of lumber is used. Sometimes your roof will use a different kind of roof framing which uses a central beam rather than lapping. If you are new to working with roof brackets or jacks limit your first experience to a one story roof with a low pitch. In such cases bracing should be designed by an engineer in accordance with technical requirement r5.

This brace is put into place in the initial construction or whenever more roofing is added to the house structure. Diagonal bracing is a structural component of just about any building. This piece is generally angled in order to spread out the weight of the structure it is supporting while attached to other pieces in order to provide the strongest assembly possible. We suggest using a roof brace kit or a field fabricated assembly using a support bracket assembly as shown in figure 15.

Once at the roof edge locate the rafters. Roof failures are often observed on areas of the building where wind pressures are concentrated. Properly installed temporary bracing dramatically increases the stability of the erected trusses and provides workers with a stiff platform to work from. Let s talk about what happens when you don t have diagonal bracing in place so you get a better understanding.

To determine the length of brace measure from support bracket assembly to point on roof where brace will be anchored. The roof structure consisting of the roof framing roof decking sheathing and any internal bracing also functions as a horizontal diaphragm and transfers the horizontal loads imposed on the roof to the supporting walls below. Step 1 check out the roof use a ladder against a side of the building to climb to the roof edge. Usually trusses are put 24 inches apart.

Bracing for putting up trusses. Flat coastal fringes fens airfields and moorland. 20 6x6 pt posts would be long enough to use as both deck support and roof support but the expense isn t justified because all that is needed to support the roof would be 4x4s. It provides lateral stability preventing collapse of a wall deck roof etc.

Preventing a roof collapse during erection is simply compulsory. For the purposes of this chapter the guidance and use of standard trussed rafter bracing does not apply to homes on or near exposed sites e g. As each truss is put up on top of opposite walls it must be put up straight and supported while the next truss is put up.
