As part of my study of portal frames I headed out to Bunnings Warehouse in Waurn Ponds. It was good to see in practise the elements of the portal fame which we have covered in class, as well as investigating slight variations on the applications, for example due to the massive span, columns are required to support the roof. On the visit I also inspected how the cladding was connected to the portal frame.
Knee joint of portal frame. Haunching is required to extend the span of the UB.
Centre column and roof bracing between rafters.
Detail of centre column connection and apex of roof. Can also see the connection of the rafters to z-purlins to roof cladding, with safety mesh inbetween.
Internal view from below of a box gutter and downpipe.
The below image shows the connection, from the interior, of the cladding to the supporting universal columns via a z-gurt.
