Roof Framing Struts

4 12 through 9 12 are the most common pitches.

Roof framing struts.

It is often used to prevent separation of the rafters during high winds but can also be used simply to frame the ceiling. They should have anti slip blocks where necessary to prevent them sliding horizontally. Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. They transfer the load of the roof to load bearing walls.

In the u s it is defined by the rise in inches to a 12 run. Vertical rise over horizontal run. 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. 3 inch rise per 12 run is a 3 12 pitch roof.

Struts may be vertically plumb or leaning then called canted raking or angled and may be straight or curved. Made from cold rolled steel and available in pre galvanized pg hot dip galvanized hd and stainless steel finishes type 316 st6 or 304 st4 our inserts are designed for high performance and reliability in every application throughout the construction and civil engineering industries. Strutting beams support the roof members where there are no load bearing wall studs available. The struts are needed in the roof frame to transfer the loads from underpurlins and other beams to the load bearing walls.

So called because it is the horizontal beam that supports the ends of the rafters at the ridge. Struts are generally more efficient the closer they are to the vertical. 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.

Purlins are placed under rafters in a perpendicular position on edge not flat. 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. The purlins are supported by vertical or slightly angled bracing. Struts and props are vertical elements which support and transfer the load from the purlins to the strutting beams.

Roof pitch the roof pitch is the numerical measure of how steep or shallow a roof is. Medical support systems by unistrut service company ensure project success we understand the medical equipment industry. Flex strut concrete inserts are the ideal solution for easily installed anchors to concrete foundations.
