Roof Truss Center Support

The use of smaller dimension lumber and the speed of installation are two more advantages of roof trusses.

Roof truss center support.

I m assuming the support you are referring to is a column below the truss. Pre manufactured stock trusses are constructed with spruce pine fir spf or southern yellow pine syp lumber. When the the trusses are in place you have eliminated the need for ceiling joist. This in itself is a time saving advantage.

These trusses the meet building code criteria as specified by structural building components of america sbca and the truss plate institute tpi. Trusses allow the builder to span greater distances between walls without installing center. The bottom core of the truss becomes the ceiling support to which the 1x4 strapping are attached. In this situation the walls of a finished attic space or room would go with the roof line.

A gable truss isn t structural and needs a continuous bearing support underneath such as a beam or wall. Roof trusses can be built to practically any roof configuration.

A gable truss sits on the end wall of a structure and has vertical studs every 2 feet or 16 inches. Extra support for the trusses can be made by placing a 2 by 4 inch piece of lumber from each truss on one side to the truss on the other side high enough to provide head room but low enough to provide support for the trusses. I am a bit surprised at this question because the purpose of a truss is to span wide spaces without center support. Gable trusses are more expensive than common structural trusses because more lumber is required.

Anyway if the span is excessive and a center support will not interfere with the space below a center support can be introduced once engineered. Some roof truss types such as stub and dual pitch contain no center and therefore lack central support. They are designed at a 4 12 pitch to be spaced 2 foot on center. Trusses are built in a factory and then delivered to your site and placed in position.
