Indoor framing: Taken to another level. Answered
We all love to mount stuff to walls to get it off the floor. Makes things so much easier to clean when the floor has nothing on it. But we also don't want to put holes in or deface the wall. Especially if we're renting. So then we get floor mounted stuff and the floor is a headache to clean. It often takes way more time to move the stuff off the floor than it takes to clean the floor!
Imagine if instead a frame was devised to line the walls. Something like 4x4's for the corners or make the entire thing out of something like 2"x2" slotted steel angle. Its extremely strong holding a lot of weight for spans of over 8' without flex. If course its not completely off the floor but pretty close. Once you have the corners and horizontals in place you can hang/bolt anything to it. It takes space organization to an all new level. Look around your room that you want to organize and try to envision being able to mount anything anywhere in that room and have it off the floor if so desired. And have it stable.
One thing I haven't figured out is how to anchor a vertical post to the floor without drilling into the floor. One option would be a high friction material like artificial rubber, maybe 1/16th or 1/8th thick that goes between a plate on the bottom of the vertical and the floor. If it was loaded with a lot of weight surely it wouldn't move.
Another advantage to this is in the event of an earthquake it would add structural integrity to the room for those of you on the west coast waiting for "the big one". Or it might act as a roll cage for your house as a hurricane blows it off its foundation!
I put this under Workshop but I have no idea if that was the best one.
