Parts Of A Timber Frame Roof

Horizontal beams supported by posts and used to support the mid span of rafters to cover longer spans.

Parts of a timber frame roof.

There is a hierarchy of timber framing at work here with trusses supporting the ridge and purlin beams. 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. A composite decking made of solid materials. Above these components is a rack of common rafters.

Depending on the design of the trusses you re making any number of bracing joints will be necessary. Very simple trusses work on a principle of thirds. 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. A timber frame truss roof with ridge beam purlins and common rafters is a stunning combination that creates visual interest and structural complexity. 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 hybrid roof system combines the conventional framing systems with false heavy timber beams.

Principal rafters form the sloping gable roof line on each bent. A horizontal timber or metal resting at the peak of the roof. Rafters and purlins are sometimes used in combination. These are used in large buildings like the traditional large old barns in the us.

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. Roof truss parts explained. 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. This horizontal member otherwise known as a ridge beam or ridge plate connects the bents at the apex of a timber frame gable.

The rafters and trusses are connected to the ridge board for a cohesive framework. Roof support timbers that extend upward from the wall plate to the topmost ridge beam are called rafters. 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.
