PURPOSE:To greatly improve strength and constructing efficiency by a method in which support metals buried and clamped with anchor bolts in stems on both ends of PC precast slab stems are placed on the steel frame of beam or girder. CONSTITUTION:Floor slabs 9, stems 8 introduced with prestress in the longitudinal direction, and precast slabs 1 having upward projections 10 on their end portions are produced. Anchor bolts 5 are buried in both ends of the stem 8, and a support metal consisting of a base plate 6 and a support steel plate 7 (vertical steel plate) is attached. The plate 7 is placed on steel frame 12 while avoiding the reinforcing bars of beam of girder 11 in steel framed structure and a precast slab l is supported. Concrete is placed for beam or girder and topping concrete 21 is placed to complete a composite slab. The end support structure of precast slabs to be connected with beam or girder in steel frame- reinforced concrete can be shaped into a simplified and reasonable structure.
