Roof Truss Elements

Rafter the basic load bearing component of the roof.

Roof truss elements.

The space between each truss is known as a bay. Collar tie prevents rafters from moving. Truss members form a series of equilateral triangles alternating up and down. A truss is essentially a triangulated system of straight interconnected structural elements.

Truss members are made up of all equivalent equilateral triangles. 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. A joint framed structure that sustained the inclined vertical or horizontal loads. Raised heel roof truss.

Here are most popular roof trusses widely used. Parallel chord roof truss. North light roof truss. Roof battens these fasten the vapour barrier to the inside of the rafters interior lining is fastened onto them.

Pairs of opposing rafters were thus initially tied together by a horizontal tie. Each type has specific design considerations and advantages and disadvantages. It is a framework typically consisting of rafters posts and struts supporting a roof bridge or other structure. In structural engineering the name truss describes a triangular design.

The main reasons for using trusses are. 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. For larger spans and thinner walls this can topple the walls. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins.

Ridge truss static connection of the rafters. A truss consist of angles channels plates and eye bars. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.
