[Object] To provide a door frame structure and a method for mounting the door frame structure which improve rigidity, prevent deformation that is caused by relative story displacement of a building in the event of an earthquake, and enable easy mounting. [Solution Means] A door frame structure 1 is indirectly mounted to a wall surface 4 via mounting angles 11 fixed to the first reinforcing members 9. Therefore, the door frame structure 1 does not follow relative story displacement of the wall surface 4 caused by lateral vibration in the event of an earthquake, so that deformation of the door frame structure 1 is minimized, and a door 31 can be opened and closed even in an emergency.

The disclosed embodiments relate to an aircraft having an interior door with a self-adjusting door jamb. The self-adjusting door jamb includes a door jamb configured to receive the interior door and a bias mechanism coupled to the door jamb and facilitating movement of the door jamb along an axis. Additionally, an angular translating mechanism coupled to the bias mechanism and facilitating angular displacement of the door jamb relative to the axis.

Installation systems and methods for fenestration units configured to be set into a rough opening from an exterior side of a building structure or wall. The fenestration units may include a retention system coupled to the frame and operable to exert a retention force on the fenestration unit to maintain positive engagement of the fenestration unit with the rough opening framing and resist extraction of the fenestration unit from the rough opening upon insertion of the fenestration unit in the rough opening from the exterior side of the rough opening.
