What kind of framework is used to help support the construction of a sloped roof?

Most sloped roofs are supported by a purlin bracing system. A board the same size as or larger than that of the rafters is placed on edge perpendicular to the rafters and attached on the bottom side of the rafters. Legs are then placed under the purlin brace and with the top notched under the purlin and the bottom placed on and attached to the top of a wall, thus transferring the weight of the roof from the rafters to the top of the walls.


How do you convert c purlins into kgs?

Instructions for swires roofing square?

The figures on the outer edge of the curve are degrees. Use these to set the angle/pitch of the roof. The figures on the inner edge of the curve are a ratio of the length of common rafter per foot or metre of run or span of roof. Take half the span of the roof in feet OR metres and multiply by the figure for the pitch of your roof this will give you the length of your rafter from birds mouth to the centre of the roof. Then make a deduction of half the thickness of the ridge board. at right angles to the bevel . The easiest way to use the bevels/angles from the square is to place the square on a piece of ply or board and mark all the bevels/angles onto the board and then use a sliding bevel/bevel square to apply the bevels/angles to the rafters and other members of the roof. No 1= Plumb & Seat cut for the Hip No 2=Plumb & Seatcut for Common Rafter No 3=Edge cut for the Hip (Mitre) No 4=Edge cut for Jack Rafter No 5=Side cut for Purlin No 4A=Edge cut for Purlin (Mitre) No 6 Lip cut to Purlin .This is the sloping cut which goes under the bottom edge of the Hip where the Purlin abutts to the Hip Rafter

When building with steel roofing/siding, a soft washer screw or nail is used to fasten the steel to the purlins. A 'goof scrrew' is used when the installer misses the purlin with the original screw, a 'stitch' and 'goof screw' are then used to replace the smaller, missed screw, thereby sealing the hole.
