Truss Roof Non Load Bearing Walls

Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres.

Truss roof non load bearing walls.

Chances are this is a non bearing wall. But there are five possible exceptions to look out for. One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing. 2 3 non load bearing walls non load bearing walls shall not carry any truss loading at any time and shall not be packed to touch the underside of the truss.

If the wall in question is parallel to the joists trusses it will likely not be load bearing. It is common to set non load bearing walls lower than the supporting walls by an amount equal to the depth of the ceiling battens plus 10mm. If there is a truss over the wall the wall is probably not load bearing since the truss bears the load. If there is a column that supports the truss found in the wall the wall still would not be load bearing because the column is taking the load.

If there are two plates refer to an engineer. Actually a quick way to determine if the wall is bearing is to cut hole at the top to see if it has one or two top plates. When joists trusses are perpendicular to the wall and bear o n the top of the wall that wall is bearing wall. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.

An example of a load bearing wall call be seen on the right. 1 when the home has an l or t shape there may be an interior bearing wall under the intersection of the perpendicular rows of trusses. For example a gable end truss may be designed with support members that transmit the roof weight load outward to the side walls allowing the end wall directly below it to have breaks or openings in it that would otherwise be impossible. Residentiall roof trusses are designed to bear only on the exterior walls at each end of the span.

An example of a non load bearing partition wall can be seen on the left. But even in that situation there is usually a doubled or tripled up truss at the intersection instead of an interior bearing wall that provides bearing along the bottom chord where the.
