Due to the large range of sizes and styles available, it is not possible to prepare an instruction manual for all styles, sizes and models. The following instruction manual is an EXAMPLE of a 6m wide x 6m long Flat Roof Carport. Things to do before you commence construction a.
Components Step 1 – Marking out the Perimeter of the Carport Mark and set-out the perimeter of the Carport with pegs and strings. In this example, the size of the carport is 6.0m wide x 6.0m long. Refer to Engineering Plans for the actual size and specifications of your specific job.
Step 2b – Footing Set-Out for Concrete Slab Mark and set-out the edges of the concrete slab to be excavated. The edge of the slab is equivalent to the string set-out of the building perimeter plus 100mm slab extension each sidewall, thereby adding a total of 200mm to the width of the Carport.
The posts are in on the endwall by 1300mm to centre line of posts as shown in Diagram As. Ensure that the diagonal measurements of the concrete slab are equal, level and square. Refer to the Engineering Plans for size and specifications of the concrete slab. TIP: Pegs and strings marking the perimeter of the building for BLOCK footing and edges of concrete for SLAB to be left in place until the position of base plates are clearly marked.
C-Purlin punching details for reference. The Rafter is to be bolted to the top of the post on an angle based on the roof pitch. Refer to the Engineering Plans for bolt size and specifications. Set-out and bore two holes at the bottom of the carport post, punching details to be the same as the top of the post.
NOTE: The post sleeve on base plate comes in 2-hole or 4-hole depending on the size and the requirements of the carport. Refer to the Engineering Plans for the specifications of the post sleeve. Step 5 – Preparation of Rafters On the outer web side of the Rafters, set-out and attach the shorter leg of the angle cleat bracket with 2 frame bolts.
Step 6 – Assemble and Stand the Carport Post and the Rafter Bolt the Rafter to the carport posts temporarily with the framing bolts supplied, one per column. Stand post in footing holes if embedded or insert the post over the post sleeve with base plate if not embedded.
Step 7 – Fixing of the Beam Place the beam in position on the side of the front posts and bolt temporarily into the angle cleat attached to the rafter. Refer Diagram H. Repeat this step at the rear pair of posts. Step 8 –...
Step 11 – Carport Frame to be Square Ensure the diagonals shown dotted are equal and prop the side that is not fixed into position. Refer Diagram K. TIP: Another option to use to check that the diagonals are equal is to calculate using this formula. Diagonal = square root (length + width Step 12 –...
TIP: If posts are embedded into concrete footings, it is recommended to wait for a few hours until the concrete is set before starting on the roofing sheets. Step 13 – Gusset Plate Knee Brace Gusset Plate knee brace are to be fitted in 2 different directions, along the sidewall between the outer flange of the end posts and the web of the rafter on 1 side only, Refer Diagram M.

Step 14 – Fit Roof Sheeting Lay the first sheet in position and ensure that the roof sheet is flush with the outside face of the rafter on the high end. This edge of the rafter should be pan fixed using 10-16 wall screws to aid in the fitting of barge capping.
