The invention relates to a cargo-hold floor for aircraft which is received on a grid structure (1). The grid structure (1) comprises essentially longitudinal members (2) and crossmembers (3). Exchangeably arranged floor plates (80), furthermore roller conveyor apparatuses (50) and lashing points (10) for the fastening of cargo articles, such as pallets, containers or vehicles, are received on the grid structure (1). Furthermore, locking units (98) are provided, which comprise lock elements (100) capable of being folded open and of being folded away. The lashing points (10) are located at the intersection points of the longitudinal members (2) and of the crossmembers (3). The roller conveyor apparatuses (50) and the locking units (98) are always located at the same installation location both in their erected position and in their countersunk drive-over and stowage position.
