Aircraft fuselage structure

An aircraft fuselage structure comprising:

• an outer skin which encloses an interior space, includes an inner surface facing the interior space, and extends along an aircraft longitudinal axis;
• a support structure arrangement comprising a plurality of frame elements which extend in a circumferential direction along the inner surface of the outer skin and are spaced apart from one another in a direction parallel to the aircraft longitudinal axis;
• a floor structure arrangement comprising a floor plate which extends in a plane parallel to the aircraft longitudinal axis, a plurality of floor support carriers which extend along a bottom surface of the floor plate and perpendicular to the aircraft longitudinal axis, and a plurality of floor support struts which extend from the plurality of floor support carriers on the bottom surface of the floor plate to the plurality of frame elements;
• wherein the floor structure arrangement is connected to the support structure arrangement via connection parts;
• wherein the connection parts of the floor structure arrangement or the support structure arrangement include one or more clamping elements and the connection parts of the floor structure arrangement or the support structure arrangement which do not include clamping elements include one or more locking elements;
• wherein the one or more clamping elements are configured to engage with the one or more locking elements;
• wherein each clamping element includes a longitudinal section having a first end and a second end, the first end being attached to a corresponding connection part for pivotable movement about a first pivot axis and the second end including a transverse section which extends away from the longitudinal section;
• wherein each locking element includes at least one locking groove configured to engage with the transverse section;
• and
• wherein the one or more clamping elements are pivotable between an engagement position, in which the transverse section is engaged with the locking groove, and a released position, in which the transverse section is disengaged from the locking groove.
