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.

Parts of a timber frame roof.

Ceiling joists are the lengths of timber or metal that the ceiling is attached to. Very simple trusses work on a principle of thirds. Ridge beams are not always required and may be omitted in some structures. 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. Roof truss parts explained. Horizontal beams supported by posts and used to support the mid span of rafters to cover longer spans. The sloping timbers include.

A barge board disguises the rafters closest to the end of of a gable roof. 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. It resembles real wood and particularly strong and stable for bearing heavy load. A composite decking made of solid materials.

These are used in large buildings like the traditional large old barns in the us. Depending on the design of the trusses you re making any number of bracing joints will be necessary. A horizontal timber or metal resting at the peak of the roof. A timber frame truss roof with ridge beam purlins and common rafters is a stunning combination that creates visual interest and structural complexity.

There is a hierarchy of timber framing at work here with trusses supporting the ridge and purlin beams. Roof support timbers that extend upward from the wall plate to the topmost ridge beam are called rafters. Rafters and purlins are sometimes used in combination. 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.

The hybrid roof system combines the conventional framing systems with false heavy timber beams. Above these components is a rack of common rafters. 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.
