Roof trusses can be said to be the skeleton of the roof as you known the skeleton produce the shape of animals even humans. Components of roof truss.

The primary segment of the roof truss that runs along the underside and supports its decking. The wall plate width see figure 7. See gusset construction below. Here are a roof truss basic parts and terms.

It is a framework typically consisting of rafters posts and struts supporting a roof bridge or other structure you will find them supporting the roofs of auditoriums. Finally there are the gussets that hold the framed truss together. A roof truss is a structural unit designed to frame a roof and to support the roof material interior ceiling insulation and forces caused by snow rain and wind.

One of a series of diagonal members of the truss that meet at the apex in order to support the roof deck and its loads. It is a waterproofing layer made of regular felt stacked above the solid. The highest point on a truss where the sloping top chords meet.

In structural engineering the name truss describes a triangular design a joint framed structure that sustained the inclined vertical or horizontal loads a truss consist of angles channels plates and eye bars. Then there is the top chord or rafters that are angled to make the roof pitch. A roof also beautify a house but the primary purpose of a roof is to protect against any form of weather.

Bearing cut or seat cut. Structural support of trusses usually walls normally with a timber wall plate.
