The invention discloses a pull rod type cargo hold floor structure and an airplane, and belongs to the technical field of airplane body structure design, in the structure, a floor cross beam and an airplane body frame are supported and connected through a plurality of V-shaped supporting frames, each V-shaped supporting frame comprises two pull rods, one ends of the two pull rods are connected to form the connecting end of the corresponding V-shaped supporting frame, the connection is movable connection, and the other ends of the two pull rods are connected to form the connecting end of the corresponding V-shaped supporting frame. The opening angle of the two pull rods can be adjusted through the movable connector, the other end opposite to the connecting end is a separated end, the separated end of the V-shaped supporting frame is movably connected with the floor beam, the connecting end is movably connected with the machine body frame, and the movable connection means that under the condition that other connection constraints are broken, the other ends of the two pull rods are separated. The pull rod can swing or rotate around the movably-connected connecting site. The warehouse bottom plate structure has the advantages of being high in manufacturing and assembling efficiency, good in stability and high in structural load transferring efficiency.
