Section 2

Section 2 of a portal frame. This shows the connection of a portal frame to the side of the building, with a universal beams and girts, there is also further fly bracing for added support. The roof is connected in a similar way with the universal beam attaching to the roof with a universal beam as the rafter, and though not seen in this section, purlins attach the roof to the rafter. Sarking is also shown on the roof and wall, the waterproof membrane to make the structure weatherproof. Kliplok roofing has been used and has been cut through for this section.

PORTAL FRAME DIAGRAM

This detail I found fascinating. This is inside the building near the centre of the shed, at the point of the roof. The I-Beams running parallel with the roof panels widen as they approach the centre and then thin out towards the edges. The roof is attached to the I-Beams in the same way as the walls, with fly bracing attached to the universal beam to spread the influence of the beam. There is also a bolt connection at the intersection of the two universal beams.

This shows how the external skin attach's to the framing. The skin attach's to horizontal steel bars and these are attached to the main framing, the I-Beams. There is fly bracing attached to the universal beams to give the wall extra support and strength. Also in this image it shows that the drain pipes are hidden away. As opposed to having them on the exterior, they run on the inside and run directly parallel with the I-Beam so they are not overly noticed.

Bunnings Warehouse, Waurn Ponds. Architect is unknown, however the design for each of these Bunnings stores remains the same. Typical shed style, with most of the internal framing exposed.
