Purpose Of A Roof Truss

Rafters have a tendency to flatten under gravity thrusting outwards on the walls.

Purpose of a roof truss.

Tremendous pressure was placed on materials that were unable to bear significant weight. 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. 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. Without roof buildings would be exposed to all kinds of elements rendering them completely useless.

Roof trusses which are structural components of houses or commercial buildings support the weight of roof timbers and coverings. At the site the truss roof frames are put together by framing carpenters. A structural framework designed to provide support and strength to a roof a truss is essential as the roof s frame. Their mass production and availability have made them much more common than conventional roofs in today s construction industry.

They bridge the space above rooms and occur at regular intervals held by longitudinal posts for support. Trusses are web shaped structures used to bear tremendous weight. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins. Man with a drill.

Basically they are triangular wooden structures designed to keep the integrity of a roof. Used in buildings and bridges of all sizes trusses allow builders to extend the dimensions of structures and create interesting shapes. A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. These trusses should never be removed or altered without the advice of a structural engineer.

Consequently engineers developed the truss. A roof truss is considered the most important key component in engineering system in a building. Here are some of the benefits of installing a roof truss. This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs.

Pairs of opposing rafters were thus initially tied together by a horizontal tie. They serve a critical function and design depends on various factors.
