PURPOSE: A hollow formation structure for a hollow slab is provided to minimize the decrease in the ultimate load of a slab and to decrease the weight of a slab, to reduce noise and vibration, and to minimize environmental pollution. CONSTITUTION: A hollow formation structure(100) for a hollow slab contains: a contour portion(10) forming the entire external appearance, having the preset height in the first direction, the preset horizontal length of the second direction intersecting the first direction, and the vertical length of the third direction intersecting the second direction, and forming the corresponding parts of the corner and the angular point in an outward convex curved surface; and a center portion(20) forming a donut hole through the center of the contour portion. |
