Zusammenfassung:The present invention relates to a PC slab for an apartment house with hollow reverse ribs and, more specifically, to a PC slab for an apartment house with hollow reverse ribs, which includes a composite cross section with all the advantages of a hollow slab, a reverse ribbed slab, and a half slab, has hollow reverse ribs, thereby being lightened, includes truss girders in a transverse direction, thereby reinforcing bending/shear stiffness, and increasing adhesion strength (composite force) with topping concrete, and anchors upper reinforcing bars, thereby facilitating placement of the reinforcing bars. According to a preferred embodiment of the present invention, the PC slab for an apartment house with hollow reverse ribs comprises: a plate-shaped bottom plate having a predetermined size; a body provided on the bottom plate, integral with the bottom plate to protrude upward in the transverse direction of the bottom plate at regular intervals, and including transverse ribs with a plurality of hollows; and a truss girder provided between the ribs, and having a lower part embedded in the bottom plate, and an upper part protruding upward from the bottom plate. 본 발명은 공동주택용 중공 역리브 PC슬래브에 관한 것으로서, 더욱 상세하게는 중공 슬래브와 역리브 슬래브 및 하프 슬래브의 장점을 모두 갖는 복합단면으로 구성되는 것으로, 중공을 갖는 역리브를 형성하여 슬래브를 경량화하면서도, 횡방향으로 트러스 거더를 구성하여 휨/전단 강성을 보강하고, 토핑콘크리트(topping Concrete)와의 부착강도(합성력) 증대시키며, 상부 철근을 긴결하여 배근을 용이하게 하도록 하는 공동주택용 중공 역리브 PC슬래브에 관한 것이다. 본 발명의 바람직한 일 실시예는 일정 크기 판 형상의 바닥판과; 바닥판의 상부에 종방향 일정 간격마다 바닥판의 횡방향으로 상부로 돌출하도록 바닥판과 일체로 형성되며, 횡방향으로 복수의 중공이 형성되는 리브로 이루어지는 본체와; 리브와 리브의 사이에서 하부는 바닥판에 매입되고 상부는 바닥판의 상부로 돌출하도록 구성되는 트러스 거더;를 포함하여 이루어진다.
