PURPOSE: An IMT(Inverted Multi Tee) slab for a long-span and a high-load of a building is provided to effectively prevent the slab from sagging and cracking using a pre-stressed precast concrete member. CONSTITUTION: An IMT slab for a long-span and a high-load of a building is composed as follows. A space(110) is formed inside a long-span panel(100) in a longitudinal direction. Styrofoam(200) is inserted into the space. Center partition walls(120) divides the space filled with the Styrofoam into multiple space parts. End protrusions(130) protruded downward are formed on the bottom of the panel. Reinforcing bars(140) are buried in the end protrusions, and parts of the reinforcing bars are branched upward. Hanging ribs(160) extended from a lower layer(150) of the panel are formed on both ends of the panel.
