The cellar floor slab is formed and ready to pour ... coming next will be the (heavy) block walls . Got the rebar and filled columns figured out , next up is the attachment of the floor joists to the top of said wall . The plan is to set some carriage bolts into the top run of block at suitable intervals and use those to secure a 2X plate - width TBD . I'll want to be able to secure a ceiling of some type to an overhanging top plate , independent of the structure above - this will also serve as a storm shelter . The question is , how best to secure the floor joists to that same top plate , so that they are both stable and secure and yet if a storm strong enough comes thru to part without taking my ceiling with it . Or , should I use the floor structure as the top/ceiling , and let the wall/floor interface part if it comes to a tornado etc ? We're actually pretty sheltered , down in a pretty deep bowl - when the tornado took out half of the nearest town (and many others on it's way to here) it skipped over The Holler , all we got was some torn up trees . Possibly pertinent detail - the bottom part of the structure - probably up to window sill height- will be clad with native stone . Probably 5-6" thick , depending on what I collect and bedded on a footing 16" below grade - frost line is at around 12" .
