Structural roof trusses are primarily used to provide support for a roof and to bridge the space above a room. They are a vital component in building construction, forming the underlying structure that the roof covering rests upon.
What is a Roof Truss?
According to the reference, a roof truss is best described as a structural framework of timbers. This framework is specifically designed to bear and distribute the load of the roof and ceiling.
How Do They Function?
These structural frameworks typically occur at regular intervals across the span of a building. They are linked together by horizontal beams known as purlins, which further contribute to the stability and support system for the roof.
Key Uses of Structural Roof Trusses
Based on the provided information, the main purposes of structural roof trusses include:
- Providing direct support for a roof.
- Bridging the space above a room, creating the necessary structural clearance and support without requiring internal load-bearing walls across the span.
These functions highlight the fundamental role trusses play in creating strong, stable, and open interior spaces by efficiently transferring roof loads to the building's walls or supports.
