Top adjustable removable hangers depend from opposed walls, beams or girders to support length adjustable ledgers, which ledgers support deck joists and decking associated therewith and upon which a concrete deck will be poured to form a slab supported upon the walls, beams or girders. Means are incorporated to permit assembly from the top of the hangers, ledgers, deck joists and decking and to permit vertical adjustment of the ledgers from the top to bring the decking to grade elevation. Further means are incorporated to permit disassembly of the hangers, ledgers, deck joists and decking from the bottom after cure of the poured concrete.
