Raised Tie Roof Truss Design

A tension tie in the upper third of opposing gable rafters that is intended to resist rafter separation from the ridge because of wind or unbalanced roof loads.

Raised tie roof truss design.

Raised heel trusses differ from their conventional truss counterparts in that they are fitted with a heel where the bottom chord intersects with the perimeter wall plate which raises the top chord. Building code limits the tie to the lower third of the distancebetween the plate and ridge. Engineered raised tie truss utilising hydraulically press plated treated timber with trusses set at centers in accordance with building regulations and structural engineer s calculation roof layout and pitch as per plan. H distance between tie and ridge.

First off the raised tie roof truss design is an extremely basic direct and utilitarian design every single current trademark. Unlike the conventional truss which is fully triangulated by virtue of its bottom chord fixing the top chords together the raised tie roof completes its triangulation at the flat ceiling to sloping ceiling intersection. Un insulated raised tie truss roof in accordance with structural engineer s calculations and specification. These trusses are the solution when the internal ceiling height is required to be higher than that of the wall plate.

A raised tie roof truss is a truss where the bottom chord making up the triangle shape moves towards the top of the triangle. A roof design gives the chance to extra floor space in the roof volume similar to a space or upper room space.

The raised tie roof truss design can go up against different style that when nitty gritty right can ooze a cutting edge feel. Consult irc table r802 5 1 for rafter span adjustment factors for rafter sizing with raised ties.

We can despite the seemingly late stage of the site measure manufacture and deliver our trusses and metal web joists in a short timeframe. The roof design was made incredibly complicated as a result of the skewed wall along the boundary line maximising the building footprint. Raised heel trusses are engineered utilizing advanced design and manufacturing techniques to meet modern building codes.
