The present invention relates to a drop-panel structure. The present invention provides a grid-type drop panel structure characterised in that it comprises: a plurality of pillars (100, 101) or wall bodies; and a linking member (210) comprising a drop panel (219) formed from concrete in such a way as to have a horizontal cross-section which is wider than the horizontal cross-section of the pillars (100, 101) or wall bodies; and in that the linking member (210) is formed in the shape of a grid in which four unit rods (212) surround the circumference of the drop panel (219), and the unit rods (212) are parallel to the surfaces of the pillars and are constituted so as to intersect each other at the same height. The present invention has the advantageous effect that a drop panel is produced and the buckling length due to sagging of the slab is reduced.
