Long span ice rink

After weeks of cruelty and neglect I have finally found some motivation for my blog. Here are some photos of the ice rink in Oakleigh, Melbourne. I have been playing there for 7 years and only just realized its a long-span portal frame construction (duh).


Here you can see the overall long span roof construction with the use of rafter beams, purlins, apex and roof cladding.


Here is a close up of the rafter/haunching and stanchion bolt connection.


Obviously theres no internal columns supporting the structure as it would be rude to place them in the middle of the rink of the fastest sport in the world, so small steel rods have been bolted from the haunching to the purlins as additional support.


Spotted a legless green seat.

Here we can see the bracing cross-spanning from rafter to rafter, for additional support against structural movement.

The back netting is connected to a steel netting frame which is joined to the roof and purlins. Also note the vertical columns supporting the end rafters.
