Abstract

The invention belongs to aeroplane structure design, and relates to the local detachable improvement of an architrave, in particular to local detachable architrave. The design is characterized in thatthe architrave at the upper end of a notch along the framework is cut off and the positions 60-100mm away from two end heads of the architrave are stepped; and the local detachable architrave connects two side faces of the notch of a framework plate with the cut-off part of the architrave on the upper end into a whole through quickly detaching type bearing locks. The local detachable architrave can be used for installation of large longitudinal apparatus needing to be detached to be maintained, without breaking the architrave and affecting the entirety of the architrave, thereby guaranteeingthe force transferring property of the architrave and facilitating the installation and maintenance of the apparatus.

Description

technical field [0001] The invention belongs to aircraft structure design, relates to the partially detachable improvement of the frame edge, in particular to a partially detachable frame edge. Background technique [0002] Due to various reasons, large longitudinal equipment needs to be installed on the aircraft structure, and some equipment needs to be disassembled periodically for maintenance and repair. For this reason, in the past, the installation and maintenance gaps of the equipment were often opened on the frame according to the shape and installation path of the large vertical equipment, and the opening area was usually large to ensure the maintenance and disassembly of the large vertical equipment. This design method of disconnecting the frame edge will sacrifice the integrity of the frame edge, reduce the strength and stiffness of the frame, and affect the overall force transmission characteristics of the frame. In order to ensure the strength and stiffness requ...
