Roof Framing Struts

So called because it is the horizontal beam that supports the ends of the rafters at the ridge.

Roof framing struts.

Medical support systems by unistrut service company ensure project success we understand the medical equipment industry. It is often used to prevent separation of the rafters during high winds but can also be used simply to frame the ceiling. Flex strut concrete inserts are the ideal solution for easily installed anchors to concrete foundations. Struts are generally more efficient the closer they are to the vertical.

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. 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. A horizontal beam that connects two rafters near the ridge of a roof.

Struts and props are vertical elements which support and transfer the load from the purlins to the strutting beams. 4 12 through 9 12 are the most common pitches. Vertical rise over horizontal run. Purlins are placed under rafters in a perpendicular position on edge not flat.

Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. 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. Roof pitch the roof pitch is the numerical measure of how steep or shallow a roof is.

Struts should be adequately supported over studs in timber walls. 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. 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 may be vertically plumb or leaning then called canted raking or angled and may be straight or curved. They should have anti slip blocks where necessary to prevent them sliding horizontally. 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.
