The invention provides a cabin section bottom plate lightweight structure. The cabin section bottom plate lightweight structure comprises a cabin section bottom plate, a grid frame and L-shaped angle pieces. The outer skin of the cabin section bottom plate is made of a glass fiber reinforced plastic material, and the grid frame is made of an aluminum alloy material; the inner side face of the cabin section bottom plate is connected with the grid frame through the L-shaped angle pieces in a glue riveting mode. The cabin bottom plate is made of an aluminum alloy material, and the internal grid frame is made of the aluminum alloy material, so that the whole weight is light, the internal supporting force is strong, and the cabin bottom plate is not easy to break; the cabin section bottom plate and the grid frame are connected through the L-shaped angle pieces in a glue riveting mode, the precision of the connecting position is high, connection is stable and reliable, and the manufacturing cost is reduced.
