Abstract

An automated storage and retrieval system includes a framework structure constructed of a plurality of upright members connected by horizontal members to define a storage grid of storage columns, within which storage columns may be stacked a plurality of storage containers. The framework structure has a rail system arranged at the upper level of the framework structure, with parallel rails in a first direction and parallel rails in a second direction perpendicular to the first direction, upon which rails a plurality of wheeled container handling vehicles travel. The container handling vehicles are equipped with a gripping and lifting device for removing storage containers from the storage columns and replacing the storage containers in the storage columns. The upright members of the framework structure have corner sections directed towards an interior of a particular storage column. The corner sections include two vertically elongated, perpendicular corner guiding plates. The corner guiding plates of the upright members are proximate to a storage column forming a guide for corners of the storage containers stored in that storage column A bracing system includes a plurality of plate members mounted between adjacent upright members. The bracing plate members include a plate segment removably mounted between two retaining profiles. Each retaining profile has a shape adapted to engage an upright member. The retaining profiles of the plate members have a box shape adapted to be securely inserted between and essentially occupy the space between the corner guiding plates of two adjacent corner sections of an upright member. A plate segment of plate member is arranged to be connected to a flange of the inserted retaining profiles. The bracing plate members are arranged to provide structural support stability for the framework structure. The guiding plates have inwardly projecting ribs that engage corresponding grooves of the retaining profiles by snap fit.
