Roof Truss Elements

Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins.

Roof truss elements.

North light roof truss. A truss is essentially a triangulated system of straight interconnected structural elements. A metal plate connected wood truss is a roof or floor truss whose wood members are connected with metal connector plates. Here are most popular roof trusses widely used.

Rafters have a tendency to flatten under gravity thrusting outwards on the walls. A truss consist of angles channels plates and eye bars. The space between each truss is known as a bay. Truss members are made up of all equivalent equilateral triangles.

Collar tie prevents rafters from moving. In structural engineering the name truss describes a triangular design. Raised heel roof truss. Interior lining lining boards fastened to the battens.

Ridge truss static connection of the rafters. 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. Rafter the basic load bearing component of the roof.

The main reasons for using trusses are. 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. It is a framework typically consisting of rafters posts and struts supporting a roof bridge or other structure. A joint framed structure that sustained the inclined vertical or horizontal loads.

Pairs of opposing rafters were thus initially tied together by a horizontal tie. Truss members form a series of equilateral triangles alternating up and down. Each type has specific design considerations and advantages and disadvantages.
