Roof Truss Elements

Truss members form a series of equilateral triangles alternating up and down.

Roof truss elements.

Each type has specific design considerations and advantages and disadvantages. In structural engineering the name truss describes a triangular design. You will find them supporting the roofs of auditoriums cinema halls stadiums railways stations airports and others. Truss members are made up of all equivalent equilateral triangles.

A joint framed structure that sustained the inclined vertical or horizontal loads. For larger spans and thinner walls this can topple the walls. The space between each truss is known as a bay. A truss is essentially a triangulated system of straight interconnected structural elements.

Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins. Parallel chord roof truss. Raised heel roof truss. Roof battens these fasten the vapour barrier to the inside of the rafters interior lining is fastened onto them.

Ridge truss static connection of the rafters. Collar tie prevents rafters from moving. A metal plate connected wood truss is a roof or floor truss whose wood members are connected with metal connector plates. It is a framework typically consisting of rafters posts and struts supporting a roof bridge or other structure.

Rafter the basic load bearing component of the roof. North light roof truss. The most common use of trusses is in buildings where support to roofs the floors and internal loading such as services and suspended ceilings are readily provided. 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.

Interior lining lining boards fastened to the battens. Pairs of opposing rafters were thus initially tied together by a horizontal tie. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.
