Zargenpfosten

Zargenpfosten are vertical structural elements that form the sides of a door or window opening in a wall frame (Zarge). They serve as the main support for the frame, carry loads from the door leaf or sash, and help transfer forces to the surrounding wall. In timber frame construction they are typically wooden members integrated into the wall opening, while in metal frame systems they may be steel or aluminum posts that are part of the Zarge assembly.

Function and role: The Zargenpfosten provide anchorage for hinges and locks, maintain the alignment of the door or window, and contribute to the stiffness and weather sealing of the installation. They work together with horizontal components such as the lintel (Sturz) and the sill (Schwelle) to form a stable opening and to carry loads from the frame to the structural wall.

Construction and installation: The posts must be true to plumb and square for proper operation of the leaf or sash. Installation involves anchoring to structural elements (studs or masonry), using appropriate fasteners and spacers, and accounting for finishing layers (plaster or cladding). In load-bearing openings, reinforcement may be required to ensure long-term stability and to accommodate hardware mounting.

Variants and related terms: Zargenpfosten are part of a Zarge, the complete door or window frame. They are closely related to other frame components such as door jambs (Türpfosten) and window jambs, and to adjacent structural members like lintels and sills. The term is common in German carpentry and timber construction literature and may be used alongside regional terminology for frame members.

Applications: Used in interior and exterior openings in timber-framed and masonry walls where a frame is installed to house doors or windows.
