Vaulted Roof Structure

A howe scissors truss is so called because its appearance resembles that of an opened pair of scissors.

Vaulted roof structure.

The mbc cut vaulted roof rafters utilise open metal web posi joists set at a predetermined angle or pitch to achieve the cut vaulted roof structure. Naturally this truss is used in buildings for creating a pitched roof. Vaulted ceilings can be constructed by either stick framing which means attaching each joist and rafter individually or by setting roof trusses that come engineered from a truss manufacturer with. Its bottom chords join together at the apex creating a pitched or vaulted ceiling.

In many cases a vaulted ceiling makes the room feel more open bringing air and light into a room. It is a substantial remodeling project. It should be approached with care and help from a residential structural engineer. Vaulted roof detail the cut or vaulted roof is an engineered system that provides open living space directly below the roof rafters as there are no horizontal ceiling joists.

This works particularly well beneath lofty double height vaulted ceilings but can also work beneath in single height rooms as this example goes to show. A vaulted ceiling in new construction is no more complicated than standard framing although it does require special roof trusses which are usually built off site. In a common truss design sloping top chords function just like rafters in conventional framing and horizontal bottom chords fill the role of ceiling joists. A vaulted roof structure opens the space below for stylistic reasons or for the addition of an attic or loft area.

Exposing elements of the roof structure including the trusses and or rafters can add character to a home. Of the four basic roof shapes shed flat gable and hip only the flat roof is. Exposed building materials can add interest. It is more expensive though.

The rafters are in compression pushing outward on the eaves walls and the ceiling joists are in tension pulling inward on the eaves walls. Engineered roof trusses may be designed to create a vaulted ceiling while still providing sufficient support for the roof s weight. The simplest kind of vault is the barrel vault also called a wagon or tunnel vault which is generally semicircular in shape. Each truss is composed of two opposing rafters and a ceiling joist.
