  • Patent number: 9315318
    Abstract: A liquid containment wall for a tank 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 at each end an overlapping section with an array of aligned holes. The holes are connected by connector plates shaped and arranged to overlie a part of the array. Each plate has a plurality of shear pegs extending at right angles and at least one hole therethrough to receive a threaded bolt so that the bolt passes through a respective one of the aligned holes of the array to clamp the plate against the overlapping panels.

  • Publication number: 20160002944
    Abstract: A cylindrical upstanding water tank is formed from a plurality of rows of corrugated curved panels bolted edge to edge with a liner extending over the cylindrical wall and support surface to contain the water within the tank. An access opening is formed in one panel of the cylindrical wall and includes a frame with a rectangular planar front flange and a rearwardly extending flange welded into the hole. Liner retention straps surround the hole to fasten an edge of the liner around the hole. An access cover plate is bolted to the front flange of the frame and carries a hoop strength plate which fastens to studs at the rear of the plane so that the plates are removable to allow service access to the interior of the tank.

  • Patent number: 8220207
    Abstract: A roof for a large diameter grain bin is formed by roof rafters inclined from a top of the wall to a top ring, with sheet metal panels in an upper row extending from the ring to a circular bottom edge and a lower row extending from a circular top edge to the wall. A circular bracket of Z-shaped cross section is carried on the rafters by upstanding support legs and provides an upper flange engaging the bottom edge of the upper row and a lower flange engaging the top edge of the lower row and an interconnecting web portion. One or both rows are supported at a mid point on a cylindrical tube bent to form a circle butting the panels and supported from the rafters on leg members which include a center strap which can be bent around the tube and two legs bolted to the rafters.
