Headed Rib Precast Concrete Slab Using Deck Plate

摘要

A hollow inverted ribsheet slab using a deck plate for constructing a plurality of ribs integrally on an upper surface and mounting a ribbed deck plate between a rib and a rib so that a longitudinal center portion of the slab is closed to form a hollow.A preferred embodiment of the present invention relates to a method of manufacturing a steel plate, which comprises a bottom plate formed integrally with concrete, a plate-shaped bottom plate, and a plurality of ribs protruding in the longitudinal direction at predetermined intervals along a width direction of the bottom plate; A deck plate configured to cover an upper space between a rib and a rib of the main body at a central portion in the longitudinal direction of the main body; An end block formed so as to close between ribs and ribs at both ends of the deck plate; And an end closure configured to close both longitudinal ends of the deck plate.
