         10 . The modular floor system of  claim 9 , wherein the precast aerated concrete slabs are connected to act as stiffeners of the support lattice and support the floor membrane. 
     
     
         11 . The modular floor system of  claim 9 , wherein the perimeter “C” channels are end welded to form a rectangle or other configuration corresponding to a desired floor quadrant and include pre-welded supports that serve as connector joints between the primary lattice support beams and the perimeter frame. 
     
     
         12 . The modular floor system of  claim 9 , wherein the primary lattice support beams have shop attached connectors to receive and attach the precast aerated concrete slabs. 
     
     
         13 . The modular floor system of  claim 9 , wherein the floor surface material is a flexible concrete impregnated cloth or rigid floor elements of precast aerated concrete or laminated structural wood. 
     
     
         14 . The modular floor system of  claim 9 , which forms a portion of a primary structure. 
     
     
         15 . The modular floor system of  claim 9 , which is inserted into a primary structure.
