Strongback Roof Bracing

Strongback roof bracing.

Underneath 2x6 strongbacks laid on edge should run continuously through the webs of all the trusses at 10 ft. The 2x6 serves the same purpose as bridging in a standard floor distributing concentrated loads over a wider area. Strongback bridging is an excellent and inexpensive way to improve the overall rigidity of the floor system and eliminate vibration. Also sometimes known as a strong back a strongback is a type of construction that helps to enhance the strength of some type of structure by adding a secondary support at a key point in the design.

Intervals one run for a 20 ft. It serves to make the floor more comfortable for those living and working in a structure. You will learn some great tricks for using braces to keep. The way strong back bracing accomplishes that is by tying the trusses together so that they accept loads as a unit instead of each truss.

In this video we cover how to brace a conventionally framed roof and why it is important to do so. Strong back braces are simply a 2x4 or 2x6 brace placed on a vertical web and is oriented perpendicular to the trusses. Truss two runs for longer trusses. The idea is to provide additional support at points in which the failure of the main support network would lead to the collapse of the structure as a whole.

Strongbacks can be altered to allow hvac installations as long as three 3 consecutive joists are attached. The purpose of strong back bracing is to create more stability in the floor. If you are building trusses it is easy to make part of the roof into a cantilevered extension. If not then you may want to consider tying the brace off with a diagonal brace much like lateral bracing is tied off with diagonal bracing to provide triangulation of the system.

A cantilever is any structure such as a roof or floor overhang that is braced internally. Background layer 5f5b72557ec17 background.
