Abstract: A framework and method of forming a single pour concrete form for walls and ceiling of a safe room. The walls secure to a concrete slab with concrete anchors. C-channel ceiling joists attach on top of vertical metal wall studs to which plywood is secured on each side to define walls forms. A metal web blocking piece attaches between adjacent ceiling joists and is spaced apart from the ends of the ceiling joist to form concrete flow channels between the ceiling and walls. A plywood strip seals between the metal web blocking pieces and the plywood on the interior walls to funnels concrete into the wall forms. Corrugated metal decking is secured to the top of the ceiling joists creating a ceiling form that does not extend to the plywood on the exterior walls, thus providing access openings for cement to flow from the ceiling form into the wall forms.

Abstract: The present invention relates to improved stairs and mezzanine that are constructed of standard steel structural components with poured concrete stair treads and the associated method for making them. The invention employs standard steel structural components to make a staircase frame that is stronger, is faster to construct, and is less expensive than those made by current methods. The framework for the staircase is constructed of steel studs, u-channel members, and metal deck material that are cut to size and screwed together. Once the metal framework is constructed and any openings caulked, concrete is poured within the framework to form the concrete steps for the stairs and any associated intermediate platform or mezzanine. Once the concrete is dry, the stairs may be painted, carpeted, or finished as desired.
