How to build a Shelter Dome?
I have been researching Shelter Domes lately. And most of the shelter domes are really temporary shelter domes. They are made out of some type of material. But after watching a video on youtube on "Domes for the World", it reminded me of this documentary I watched on Discovery channel about five or six years ago. This genius engineer was trying to prove people that it is not so hard to build a dome shape building. and he actually prove this by building a dome shape structured building in one day. And he executed this ingenious idea by using flexible steel rods and mesh wire and poured concrete on top of this weaved flexible steal rods. He formed this dome shaped concrete building by having a balloon underneath this steal rods and mesh wire and pumped it with air. So when the concrete hardened, it hardened in a form of a dome. Smart huh? Yep I remembered that. And it reminded me when I watched the "Domes for the World" video on YouTube.com They are using similar techniques. Without the mesh wire ofcourse. And I want to imitate this.
I totally agree with using mesh wire on top of the shelter dome frame. and maybe even in the interior. But I do have an idea.
What if in the interior of the dome, you use a SPRAY FOAM INSULATION, prior to applying the exterior concrete. I think this technique will help hold and form and exterior concrete. And then just sand the interior foam insulation for a smooth surface. and use stucko on top of the foam and then just spray pain the inside. This will give you a hard shell instead of using some type of vinyl or canvas material. and I think your Shelter dome will last longer and stronger.
ABOUT WINDOWS & DOORS
I want circular windows. So I'm thinking of executing this by placing a plastic circular tube on certain areas prior to pouring concrete.
I think I just found my solution.
But I couldn't sleep so I did more research on Goggle.com and found this great article. The same exact idea I have on building a Shelter Dome. Check it out.
