IMPROVING STRUCTURE INTEGRITY WITH TOPPING CONCRETE AND IMPROVED SHEAR LOAD CARRYING OF HOLLOW SLAB STRUCTURE USING SHEAR REINFORCING BAR AND CONSTRUCTING METHOD USING THE SAME

摘要

The present invention provides a structure for enhancing a shearing force of a hollow slab and the unity with topping concrete by using a shearing force reinforcing rebar. The present invention includes: a hollow slab which is made of a precast concrete slab, is penetrated in the longitudinal direction, and has one or more hollow gaps formed in the width direction; a lower plate which is connected to the lower end of a spacing gap formed by arranging the hollow slab and another adjacent hollow slab in the width direction; and the shearing force reinforcing rebar which is installed by being attached to the upper part of the lower plate. The lower plate is connected in the longitudinal direction of the hollow slab between adjacent hollow slabs, and the topping concrete is poured onto the upper part of the hollow slab after installing the lower plate where the shearing force reinforcing rebar is attached.
