We’ve very excited about the K-Span steel arch roof that will be covering our container house. But of course, we need something in place to which the steel roof can attach to the containers. Kevin has been busy preparing for the roof installation.
If you want to find out more about the roofing system we will be installing, here is our original post on the system we have chosen.
There were a few things that Kevin had to weld together and install on the construction:
- C-Channel on the exterior walls on the North and South side of the building
- Raised C-Channel on the interior of the North and South side of the building
- Steel arches (the wall plate) that will follow the curve of the roof on the East and West side of the building
First of all though, we needed all the steel.
A Delivery from Steel And Pipe
There was obviously only one company from which we wanted to get our steel. Steel and Pipes for Africa have worked closely with Small Scale Engineering for years now. Therefore, Kevin called them up and ordered several tonnes of steel. Delivery was made shortly thereafter.
Kevin helped to offload while I stood by taking photos and doing a quick double check of our order.
Preparing for the K-Span Roof: Interior and Exterior C-Channels
The exterior C-channels were the easier section to weld into place. Kevin and Louis clamped the channel against the side of the container. After that, they went along the length and welded it where necessary. Kevin welded the channels with the open side facing outwards. This should allow the C-channel to flex a bit when the K-Span steel arch roof is bolted on. You might also note in the below photo that the C-channels have been pre-galvanized in order to reduce rust. We touched up the welding seams with red oxide paint.
The interior C-channels were a bit more complicated because they had to be raised above the height of the container itself in order to meet the roof. Kevin welded several upright posts in place. On the lower container, Kevin, Louis and myself stood on the roof and helped Kevin raise the C-channel into place. We held it still while Kevin welded it to the uprights. I was not able to help with the double-storey (North) side as I was not on site that day.
Preparing For the Roof – The Steel Arch
After some careful calculations, Kevin took three lengths of rectangular tubing. At regular intervals, he cut through the steel, leaving the last side intact. He then bent the tube in against itself and welded the seam. He joined the three smaller arches and made one very long arch that is at the same radius that the roof will be.
Next up, was to weld the arches on the East and West side in place. Again, Kevin used upright steel posts to further strengthen the curved wall plate and hold it in place. The roof plates thesmelves won’t be relying on the arch for stability, but we will use this frame and the arched wall plate to fix the cladding to make a wall.
Before we go, we have two more photos of interest to show you.
The view from up here is pretty good!
A friend took an aerial photo of the project for us! How awesome is this? Can you see the steel arch wall plate over the white (East) container? Can you spot the Nissan we recently refurbished?
