Parts Of A Timber Frame Roof

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

Parts of a timber frame roof.

Roof support timbers that extend upward from the wall plate to the topmost ridge beam are called rafters. A barge board disguises the rafters closest to the end of of a gable roof. Horizontal beams supported by posts and used to support the mid span of rafters to cover longer spans. A composite decking made of solid materials.

Ridge beams are not always required and may be omitted in some structures. There is a hierarchy of timber framing at work here with trusses supporting the ridge and purlin beams. Above these components is a rack of common 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.

Principal rafters form the sloping gable roof line on each bent. 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. 3 06 timber frame timber flat roof 3 07 timber frame timber flat roof with parapet 3 08 timber frame lintel at window head 3 09 timber frame windows and doors jambs and cills specification within an example should 3 10 timber frame ground bearing floor insulation above slab 3 11 timber frame ground bearing floor. These are used in large buildings like the traditional large old barns in the us.

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 sloping timbers include. The rafters and trusses are connected to the ridge board for a cohesive framework. A horizontal timber or metal resting at the peak of the roof.

The hybrid roof system combines the conventional framing systems with false heavy timber beams. Roof truss parts explained. 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 timber frame truss roof with ridge beam purlins and common rafters is a stunning combination that creates visual interest and structural complexity.

Rafters and purlins are sometimes used in combination. Very simple trusses work on a principle of thirds. Depending on the design of the trusses you re making any number of bracing joints will be necessary.
