PURPOSE: A slab construction material capable of fixing a reinforced truss on the upper side of a metal deck is provided to prevent rust which is caused by welding, since the concavo part of the lower end of a lattice reinforcement is not welded; only a transverse reinforcement is welded on the convex part of the metal deck. CONSTITUTION: A slab construction material (10A) comprises a metal deck (11), a reinforced truss (12), and multiple transverse reinforcements (13). The metal deck is composed of multiple convex units, and the reinforced truss is formed to have an upper end reinforcement (24), a lower end reinforcement (25A), and lattice reinforcements (26A,B). The top end convex part of the lattice reinforcement is welded to the upper end reinforcement; the middle part is welded onto the lower end reinforcement; and the transverse reinforcement is welded onto the convex part of the metal deck by being arranged on the lower end concavo part of the lattice reinforcement. The lower end concavo part of the lattice reinforcement is inserted into the upper side of the metal deck and the transverse reinforcement. |
