Roof Framing Struts

Struts and props are vertical elements which support and transfer the load from the purlins to the strutting beams.

Roof framing struts.

They should have anti slip blocks where necessary to prevent them sliding horizontally. Medical support systems by unistrut service company ensure project success we understand the medical equipment industry. So called because it is the horizontal beam that supports the ends of the rafters at the ridge. The braces struts or kickers should be within every 4 and should not be at a greater than a 45 degree angle towards the roof slope lower side.

Definition of structural ridge or ridge beam used in roof framing a structural ridge beam is a horizontal beam placed at the peak or ridge of a roof and is designed to carry much of the live and dead loads or weight of the roof structure by itself. Struts are generally more efficient the closer they are to the vertical. Roof pitch the roof pitch is the numerical measure of how steep or shallow a roof is. A horizontal beam that connects two rafters near the ridge of a roof.

With today s heavy medical equipment and increasingly stringent design criteria unistrut can design fabricate and install overhead structural supports for demanding hospital medical center or out patient clinic applications. It is often used to prevent separation of the rafters during high winds but can also be used simply to frame the ceiling. 3 inch rise per 12 run is a 3 12 pitch roof. A diagonal member of the truss that has a compressive force acting on it and used to maintain rigidity and add strength to the structure.

Struts may be vertically plumb or leaning then called canted raking or angled and may be straight or curved. Flex strut concrete inserts are the ideal solution for easily installed anchors to concrete foundations. The purlins are supported by vertical or slightly angled bracing. In the u s it is defined by the rise in inches to a 12 run.

Struts should be adequately supported over studs in timber walls. 4 12 through 9 12 are the most common pitches. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. They transfer the load of the roof to load bearing walls.

Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. The struts are needed in the roof frame to transfer the loads from underpurlins and other beams to the load bearing walls. Strutting beams support the roof members where there are no load bearing wall studs available.
