Abstract

A modular container wall unit and containment system formed therewith, each wall unit includes a central panel having wing-like side panels integrally formed on opposite sides thereof and angularly intersecting the central panel at an angle such that, when the side panels of another modular unit are affixed to the central panel of the present unit, and one or more like units are affixed to the second and third units, a chamber is formed which, when combined with a bottom panel and a top panel, defines a container. The central panel of each unit is designed to include recessed areas adapted to mate with the side panel of another modular unit to facilitate the expansion of the system to form an adjacent cell or chamber. Furthermore, the modular unit is configured to withstand lateral loads and maintain system integrity.

Dependent claims

A wall unit for use in forming a single cell or multicellular containment structure and comprising a generally rectangular center panel and integrally formed and rectangularly configured side panels extending from opposite side edges of said center panel and lying in planes which angularly intersect a plane including said center panel at an angle selected from the set of angles consisting of 60.degree., 90.degree. and 120.degree., said center panel including a central portion disposed between two side portions, each said side portion being configured to mate with and be fastened to a side panel of a like wall unit, said central portion including a first web forming at least part of a first surface of said wall unit, and a second web forming at least a part of a second surface of said wall unit opposite said first surface, said first and second webs being joined at opposite extremities contiguous with said side portions and being separated at their midportions to form a cavity extending along the vertical centerline of said wall unit, said first and second webs having the characteristic that, in resisting loads applied to said inner and outer surfaces, they tend to extend the width of said center panel.

A containment system comprising:

a base including a horizontal upper surface;
a plurality of interconnected wall units disposed upon said base and combining with said upper surface to form at least one containment chamber having a polygonal plan-form, each said wall unit including a rectangular center panel and integrally formed and rectangularly configured side panels extending from opposite side edges of said center panel and lying in planes which intersect a plane including at least a part of said center panel at a predetermined angle, each said center panel including a central portion disposed between two side portions, said side portions being matingly engaged to and fastened to a side panel of a like wall unit positioned adjacent thereto, said plurality of wall units being interconnected in side-by-side relationship to form a containment structure, said central portion including a first web forming at least part of a first surface of said wall unit, and a second web forming at least a part of a second surface of said wall unit opposite said first surface, said first and second webs being joined at opposite extremities contiguous with said side portions and being separated at their midportions to form a cavity extending along the vertical centerline of said wall unit, said first and second webs having the characteristic that, in resisting loads applied to said inner and outer surfaces, they tend to extend the width of said center panel.
