Back in April we had a large pine land on top of one of the work trailers, and rearrange the roof. It was just one of the million trailers like it, aluminum sheets, plywood floor overhead door and steel roof that is on every construction site. Since the ceiling was in pieces it was real easy to see how the trailer was originally built.
When I got to looking it became real difficult to understand how trailers like it have a 20 year life. The big thing about them is every piece transfers load to another piece, with the exception of the 1/4" drywall.
Since one of my buds is a professional tin knocker who hadn't worked in months I had him swing by and help me fix the trailer enough to keep it in use another 10+ years.
The roof/ceiling is supported every 24" with a "truss". There is 5" of bow in the factory truss giving the roof just enough slope to cause water to run off. That proved it doesn't take near as much as architects and engineers claim to hold a roof up.
I ripped some 2x 6s into strips slightly heavier than the originals and some 1/4 plywood and set a jig up on an I beam. A few hours later I had 6 replacement trusses ready to slip into place.
Once I had them mounted I decided to bowstring them with 3/4" steel strapping to increase the weight handling capacity.[/img]
Once they were in a couple new sheets of steel went over the roof and a layer of rubber got glued on. I'm told the rubber will outlast the roof.
Now I'm about to fabricate a shed type container for some lawn tractors. Officially according to law it will be a NotA building. NY has very strict rules, laws and definitions what a building is. I figured out a way to create NotA buildings.
This one will be made from a free 12 x 12 overhead door that got replaced. That will give me sidewalls. The end will be a collection of pannels from Hauserman steel office partition.
The NotA foundation will be 2 pieces of 6 x 6 galvanized guardrails and uprights will be span beams from pallet racking or pipe. Headers will be pallet rack uprights.
I'll be damned if I pay 14 bucks for a compressed straw roof rafter so I'm going to make some more bowed trusses.
If I could figure out how to insert pictures on this board there would be a picture of my beautiful homemade trusses.
