Abstract: A rack storage system includes storage racks forming unit load storage locations arranged next to one another on storage planes on top of one another. The racks include either exclusively outer storage racks or outer and inner storage racks and are installed stationarily on a bottom plate. One or multiple rack aisles are between the racks in an x-direction. Automated storage and retrieval units transport unit loads and building walls are mounted on the outer racks via a support structure and form wall elements. The support structure includes profiled support elements affixed, by spacers, to the outer rack. The wall elements are mounted on the support elements, each being affixed, by respectively one spacer, to the outer rack in separate mounting regions (37) provided separate from one another. An adjuster per spacer adjusts a horizontal distance between a profiled support element and the outer rack. One fixer per spacer fixes the adjusted distance.

Abstract: The invention relates to a rack storage system comprising storage racks which form storage locations for unit loads, which storage locations are arranged next to one another on storage planes located on top of one another (4), which storage racks comprise either exclusively outer storage racks (2a) or outer storage racks (2a) and inner storage racks (2b) and are installed in a stationary manner on a bottom plate (9), one or multiple rack aisles between the storage racks in an x-direction, automated storage and retrieval units (7) for transporting unit loads and building walls (30, 32) which are mounted on the outer storage racks via a support structure and form wall elements (31). The support structure comprises profiled support elements (36) affixed, by means of spacers (35, 35a, 35b), to the outer storage rack. The wall elements are mounted on the profiled support elements.
