Document Type and Number:
Japanese Patent JP2019116767
Kind Code:
A
Abstract:
To provide a deck plate and its manufacturing method, which secure the rigidity around the longitudinal end part, and enable the prevention of concrete from leaking out at the longitudinal end part of the deck plate during casting without a separate member for preventing the concrete leakage being fitted.SOLUTION: A deck plate 1 for concrete slab is formed by bending a steel plate into a rectangular shape in plan view, and comprises a slab support part 2 shaped like a rectangular flat plate to support the bottom surface of the concrete slab. A buckling-prevention rib (angle rib 23) for preventing buckling is formed along the longitudinal direction on the slab support part 2. The longitudinal end part of the buckling-prevention rib (angle rib 23) is crushed at a designated point away from the end so that the bottom edge of the buckling-prevention rib (angle rib 23) and the bottom edge of the other part of the slab support part 2 are on the same plan.SELECTED DRAWING: Figure 2
