Abstract: Method and apparatus for connecting a floor system (30) to a support structure (33) in a building or other structure. A formed section (41) is positioned on the top of the structural stud members (34) of the support structure (33) and has two vertical sides (42, 43) which open upwardly. Tie members (45) maintain the formed section (41) in its configuration while concrete is being poured into the section (41). The floor system (30) is supported upon the formed section (41) with concrete (35) added thereto.
