Purpose Of A Roof Truss

A structural framework designed to provide support and strength to a roof a truss is essential as the roof s frame.

Purpose of a roof truss. Roof trusses which are structural components of houses or commercial buildings support the weight of roof timbers and coverings. A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites. They serve a critical function and design depends on various factors. Trusses are web shaped structures used to bear tremendous weight.

Pairs of opposing rafters were thus initially tied together by a horizontal tie. Man with a drill. Without roof buildings would be exposed to all kinds of elements rendering them completely useless. The raised heel roof truss reduces condensation problems since the truss creates a vapor barrier and is commonly seen in humid climates where mold is a common issue.

This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs. The space between each truss is known as a bay. Here are some of the benefits of installing a roof truss. Consequently engineers developed the truss.

Tremendous pressure was placed on materials that were unable to bear significant weight. Used in buildings and bridges of all sizes trusses allow builders to extend the dimensions of structures and create interesting shapes. These trusses should never be removed or altered without the advice of a structural engineer. Basically they are triangular wooden structures designed to keep the integrity of a roof.

A roof truss is considered the most important key component in engineering system in a building. Usually they are constructed from pieces of timber or steel which are nailed bolted or pegged together to form a mutually supporting and strong base for a roof. Their mass production and availability have made them much more common than conventional roofs in today s construction industry. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.

They bridge the space above rooms and occur at regular intervals held by longitudinal posts for support. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins.
