Liquid containment system

摘要

A liquid containment barrier is formed by corrugated panels connected end to end and supported by upstanding brackets at spaced positions around the peripheral wall and a liner attached to the wall. Each panel has the top edge as a raw edge with a plurality of elongate extruded plastics spring channel members engaged over the top edge. A plurality of additional clamp collars are arranged to surround a part cylindrical portion of the channel members to bridge between panels and to form a local clamping force on the channel member. Each bracket has an inner vertical edge engaging the panels and a rod member hooked to the brace at the lower end and engaging over the channel members at the upper end. The bracket also includes an upwardly extending flange parallel to the inner edge to form a channel for the bottom edge of the panel.

主权项

1. A liquid containment barrier comprising:
a plurality of panels, each having a top edge, a bottom edge, an inner surface, an outer surface, a first end and a second end such that the panels can be arranged with the first end of one panel connected to the second end of a second panel to form a peripheral wall surrounding an area to be confined; the top edges of the panels being arranged at a common height to define a common top edge of the peripheral wall; wherein each panel has the common top edge as a raw edge of a single upstanding metal sheet standing upwardly from the panel without any additional flange portion where the common top edge defines the inner surface and the outer surface spaced by a thickness of the panel; a plurality of support bracket members arranged to stand vertically at spaced positions around the peripheral wall outside the peripheral wall for connection to the panels to hold the panels and the peripheral wall vertical; and a plurality of elongate extruded plastics spring channel members each engaged over the common top edge at positions along the common top edge; each of the extruded spring channel members comprising a cylindrical portion having a hollow interior engaged over the common top edge with the common top edge entering into the hollow interior of the cylindrical portion; the cylindrical portion of each channel member having at least three longitudinal parallel ribs extending inwardly from an inside surface thereof defining the hollow interior; the parallel ribs including a central rib aligned with the pair of legs and a first rib on one side of the central rib and a second rib symmetrically with the first rib on an opposed side of the central rib; said first and second longitudinal ribs being spaced apart relative to the central rib so as to define therebetween first and second parallel grooves on the inside surface of the cylindrical portion thereof so that the common top edge is received and located in the first groove where the common top edge is inclined inwardly and in the second groove where the common top edge is inclined outwardly; wherein each bracket member includes an upstanding brace portion with an inner vertical edge engaging and supporting the outer surface of one of the panels; and wherein each bracket member includes a rod member; the rod member having a lower hook end defined by a first bent portion of the rod member engaging onto the brace portion at a position thereon outward of the inner edge; and the rod member having an upper arcuate hook defined by a second bent portion of the rod member end engaging over the cylindrical portion of the extruded spring channel member at the common top edge of the panel; the extruded spring channel member being held captured by the upper arcuate hook so that lifting movement of the extruded spring channel member causes upward pulling forces on the rod member to resist the lifting; the upper arcuate hook being free from connection to components inside the peripheral wall so that all upward puling forces are communicated to the rod member.
