Abstract: PURPOSE: A composite beam for reducing floor height without separate refractory coating and a beam-slab bonding structure using the same are provided to remove a need for separate refractory coating in a state that a lower flange is completely buried at concrete for composition. CONSTITUTION: A composite beam for reducing floor height without separate refractory coating comprises a steel beam(10), a mold board(15), and concrete. The steel beam comprises a lower horizontal plate(11), a central vertical plate(12), an upper horizontal plate(13), and a wing plate(14). The first three plates make an H-shaped section. The mold board is coupled to the wing plate on the lower part of the steel beam. The concrete is charged in a space surrounded by the wing plate and the mold plate and is integrated with the steel beam.

Abstract: PURPOSE: A method of constructing an in-site rebar concrete beam using a preinstalled precast concrete slab is provided to reduce costs and enhance constructability since timbering for supporting a beam mold can be omitted. CONSTITUTION: A method of constructing an in-site rebar concrete beam using a preinstalled precast concrete slab is as follows. Timbering(11) is installed. A precast concrete slab(21) is placed on the timbering. A beam mold(31) pre-assembled is transported. A bolt is fastened to an insert nut pre-installed on the precast concrete slab to suspend the mold. Rebar is arranged in the beam mold and on the precast concrete slab. Beam concrete(41) and additional concrete(51) are simultaneously placed. After the concrete is hardened, the beam mold and the timbering are removed.
