摘要

The door leaf (1) comprises a single groove, which has an insert connected on both sides with a cover plate. The insert has a central position and frame pieces surrounding at its peripheral surface. The two cover plates have a hard fiber layer and the central position is surrounded at its two longitudinal side surfaces and at a narrow side surface with the interior lying frame piece made of Intrallam(RTM: Laminated strand lumber). The hard fiber layer is formed of two hard fiber plates, which are connected by an aluminum insert. An independent claim is included for a frame, particularly a steel enclosure frame, which has a door leaf and a metallic bracket section made of iron or steel.
