Abstract
A z-shaped beam for hook-in type shelving systems that can support mezzanine floors and walkways either with its top flange or its bottom flange, and in the latter case can act at the same time as kickplate and/or shelf-support while supporting the edge of the floor structure, thus allowing a series of these z-beams to completely support a floor structure by forming two sets of perpendicular beams, the distance between these beams being no more than the distance between posts.
Claims3
A multi-story shelving assembly comprising:
- (a) posts having a plurality of openings, said openings spaced from each other along the post;
- (b) z-shaped beams having a web portion, a number of projections from said web and spaced apart such that they can be received into the openings of the posts;
- (c) flooring panels;
- said z-shaped beams having an upper and a lower flange spaced apart from each other a distance a whole number times the distance between the openings in the posts, and the hooks such that one z-shaped beam can be hooked into one group of openings in a post, and another z-shaped beam with identical cross-section can be hooked into another group of openings in a post, such that the top surface of the upper flange of one z-shaped beam is at the same horizontal level as the top surface of the lower flange of the other z-shaped beam, allowing support of the flooring panels simultaneously by both the upper flange of the first z-shaped beam and the lower flange of the second z-shaped beam.
