Abstract

The invention relates to a load introduction structure for an aircraft, comprising two lateral frames which are arranged opposite one another in the two lateral regions of a fuselage airframe structure of the aircraft and adjoin a continuous floor surface which rests on a floor frame. The two lateral frames are connected via the top thereof by a ceiling frame, the ceiling frame being suspended from a ceiling region of the fuselage airframe structure. Each lateral frame is divided into at least two lateral frame segments. At least three track portions which extend parallel to a longitudinal axis of the aircraft are arranged on each lateral frame segment. The lateral frames are connected to the fuselage airframe structure, the ring frames in particular, by a plurality of x-rods, y-rods and y-cardan rods. The load introduction structure is largely uncoupled according to the invention from the fuselage airframe structure of the aircraft inter alia by a plurality of coupling members arranged between the track portions to form gaps in order to compensate for load-induced and/or thermally-induced deformations, in particular changes in length, of the fuselage airframe structure.
