Storage structure having two-piece beams

摘要

A storage structure includes at least four posts which provide the vertical framework for a rack arrangement. The posts are interconnected in pairs to form end frames and have vertical rows of slots in opposite surfaces. Longitudinally extending channels are connected to the posts by hooks having lower camming edges. After the hooks are received in the slots in the posts, the channels move downward to tighten the connection. The channels are used in matching pairs, and upwardly extending tabs are formed in the lower flange of the outer channel whereas the upper flange is formed with pockets or slots. The inner channel includes downwardly extending tabs in its upper flange, which are received in the slots or pockets of the outer channel, and similar pockets or slots in its lower flange which receive the upwardly extending tabs.
