Purpose Of A Roof Truss

Here are some of the benefits of installing a roof truss.

Purpose of a roof truss.

A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites. 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. Used in buildings and bridges of all sizes trusses allow builders to extend the dimensions of structures and create interesting shapes. 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. Man with a drill. A roof truss is considered the most important key component in engineering system in a building. For larger spans and thinner walls this can topple the walls.

The space between each truss is known as a bay. A structural framework designed to provide support and strength to a roof a truss is essential as the roof s frame. At the site the truss roof frames are put together by framing carpenters. Consequently engineers developed the truss.

They serve a critical function and design depends on various factors. Trusses are web shaped structures used to bear tremendous weight. These trusses should never be removed or altered without the advice of a structural engineer. 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.

Their mass production and availability have made them much more common than conventional roofs in today s construction industry. Tremendous pressure was placed on materials that were unable to bear significant weight. 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. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.

This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs. Without roof buildings would be exposed to all kinds of elements rendering them completely useless.
