ABSTRACT:
The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame. To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame. Each lateral caulking element engages with and is fixed to the interior of the related upright. Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate carried by the related upright. The vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat. This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.
