DE-MOLDING DECK HAVING A HIGH BINDABILITY CAPABLE OF WELDING THE LOWER PORTION OF A TRUSS GIRDER ON THE SPACER HEAD OF A SPACER

摘要

PURPOSE: A de-molding deck is provided to prevent the collapse of a duct and a ceiling finishing material due to the separation of a spacer from a slab when the vertical loads of the duct and the ceiling finishing material increase.;CONSTITUTION: A de-molding deck(A) includes a truss girder(10), a mold panel(20), and spacers(30). The truss girder is formed by welding the inner sides of the upper ends of lattice members(12) on both sides of a upper chord(11). Through holes(21) are formed directly below lower chords(13) of the truss girder on the mold panel. The spacers are bound between the truss girder and the mold panel, and the mold panel is detachable to the spacer.;COPYRIGHT KIPO 2013
