Purpose Of A Roof Truss

Without roof buildings would be exposed to all kinds of elements rendering them completely useless.

Purpose of a roof truss.

The space between each truss is known as a bay. Tremendous pressure was placed on materials that were unable to bear significant weight. Man with a drill. These trusses should never be removed or altered without the advice of a structural engineer.

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. Roof trusses which are structural components of houses or commercial buildings support the weight of roof timbers and coverings. A roof truss is considered the most important key component in engineering system in a building. They serve a critical function and design depends on various factors.

Pairs of opposing rafters were thus initially tied together by a horizontal tie. For larger spans and thinner walls this can topple the walls. Rafters have a tendency to flatten under gravity thrusting outwards on the walls. Basically they are triangular wooden structures designed to keep the integrity of a roof.

Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins. This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs. Their mass production and availability have made them much more common than conventional roofs in today s construction industry. 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. 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. Trusses are web shaped structures used to bear tremendous weight. Consequently engineers developed the truss.

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. A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites.
