Parts of a timber frame roof.

Ridge beams are not always required and may be omitted in some structures. This horizontal member otherwise known as a ridge beam or ridge plate connects the bents at the apex of a timber frame gable. Horizontal beams supported by posts and used to support the mid span of rafters to cover longer spans. This can be made to look exactly like the heavy timber systems but by using either trusses or stick built framing in combination with either decorative beams or false timber the costs are much lower than the full heavy timber system.

These are used in large buildings like the traditional large old barns in the us. Rafters and purlins are sometimes used in combination. One of a series of diagonal members of the truss that meet at the apex in order to support the roof deck and its loads. Roof truss parts explained.

The hybrid roof system combines the conventional framing systems with false heavy timber beams. Very simple trusses work on a principle of thirds.

Their function is similar to that of a fascia board however it runs parallel to the rafters on an angle at the skillion end of a gable. There is a hierarchy of timber framing at work here with trusses supporting the ridge and purlin beams. Trusses the slanting timbers forming the triangular framework at gables and roof braces slanting beams giving extra support between horizontal or vertical members of the timber frame herringbone bracing a decorative and supporting style of frame usually at 45 to. The rafters and trusses are connected to the ridge board for a cohesive framework.

Principal rafters form the sloping gable roof line on each bent. A super basic a frame roof will require anywhere between 4 and 8 depending on the size of the rafters with plumb cuts necessary for each angle in the brace. It resembles real wood and particularly strong and stable for bearing heavy load. Above these components is a rack of common rafters.

A timber frame truss roof with ridge beam purlins and common rafters is a stunning combination that creates visual interest and structural complexity. A barge board disguises the rafters closest to the end of of a gable roof. Ceiling joists are the lengths of timber or metal that the ceiling is attached to.
