Attaching Containers Together

Are there available clips/clamps to join containers at corners?  If so, do they allow joining at 90 degrees?  What about stacked at 90 degrees?  Or is welded assembly considered better?

There are clamps available to join containers together. It is supported by two separated axes in opposite direction at one end at the axis side of the clamp structure. It is used to join both shipping containers together so rigidly and so strong attachment of containers. I think they allow joining at 90 degrees.

I gave up on shipping container houses. One guy welded them together at the top. That may even be waterproof. From what I could tell, water drainage off a single shipping container is fine and the roof is not easily going to rust. When you join the 40 ft. long side, even if the weld is waterproof, a flat roof has to drain water somehow. The corrugated surface does not lend itself well to draining. If you join the long sides, the most logical conclusion is to put a conventional roof above it. How? If you use wood trusses, how do you attach them to the middle of the roof? It's possible, but not that elegant; it can only connect well at the corners. Weld metal trusses on? That's a lot of specialized labor. Maybe some bolt together steel roof trusses. A conventional roof is the most logical way to get the water off the flat roof surface. If you do a flat roof, then any water leak is a disaster as you have metal surfaces, wires and water. Then a shipping container has basically no thermal mass to keep you warm in winter and heat must constantly be pumped into it. I'm no longer planning one.

I agree they are clamps available to join containers together.

Can't speak for anyone else, but if your not going to take them apart and move them at a later date then I think welding them togeher is your best bet and that also makes it water proof as well between the joined containers. Provided you prepped the weld area correctly and had a good welding unit and welder do the work. I plan on useing the clamping system they have for stacking and transporting the containers on ships to hold mine plumb and level while I get it all welded up, but other then that I prefer knowing my joints are sealed with weld as opposed to trusting a grommet or weatherstripping to hold for the life of your home. And as far as shedding water you wont need much of a slope ( maybe a 2 to 3 inch drop. ) to get the water off so if you reuse the metal you took out of the middle, again depending on how much you cut out but you could use the left over metal to make a shallow peak on top like a salt box style roof to keep the water off. There are many more solutions out there I am sure, but thats just my .2 cents worth!

The bridge clamps and twist locks make use of the container corner casting connecting shipping containers.
