Roof truss center support.

Gable trusses are more expensive than common structural trusses because more lumber is required. 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.

A roof truss is a structural unit featuring a framework of small members that act as a larger member. Trusses are built in a factory and then delivered to your site and placed in position. The use of smaller dimension lumber and the speed of installation are two more advantages of roof trusses. Some roof truss types such as stub and dual pitch contain no center and therefore lack central support.

I am a bit surprised at this question because the purpose of a truss is to span wide spaces without center support. When the the trusses are in place you have eliminated the need for ceiling joist. In this situation the walls of a finished attic space or room would go with the roof line. Hip roofs are more stable than gable roofs and more resistant to strong winds and hurricane.

A gable truss sits on the end wall of a structure and has vertical studs every 2 feet or 16 inches. The bottom core of the truss becomes the ceiling support to which the 1x4 strapping are attached. Trusses allow the builder to span greater distances between walls without installing center. I m assuming the support you are referring to is a column below the truss.

This in itself is a time saving advantage. They are designed at a 4 12 pitch to be spaced 2 foot on center. Roof trusses can be built to practically any roof configuration. A gable truss isn t structural and needs a continuous bearing support underneath such as a beam or wall.
