GRAIN BIN - Westeel

BIN ROUNDNESSIt is imperative that the bin be as perfectly round as possible. The use of a string anchored and centeredon the concrete foundation to scribe a circle is required (see chart below for calculated radii. Theseradiuses are 3/4" smaller than the wall sheet radius at the bottom, so that the scribed circle can be seenduring assembly). A perfectly placed ring of sheets should be 3/4" on the outside of this line all the wayaround. This should be the first step in assembling a bin. The maximum amount that a bin can be out ofround is 3/4" on the radius, when measured from the center of the bin. In addition the wall sheets mustform a smooth circle with no flat or elongated portions. Before anchoring the bin to the foundation, ensureagain that the bin is round, within tolerance. Locate anchor bolts towards the outside of the anchor boltholes (away from bin) to permit the incremental expansion that can occur with the initial filling.NominalBin Dia.In feetScribe RadiusNominalBin Dia.In feetScribe RadiusNominalBin Dia.In feetScribe Radius15 7 ft 4.77 in. 33 16 ft 4.20 in. 60 29 ft 9.35 in.18 8 ft 10.68 in. 36 17 ft 10.11 in. 72 35 ft 8.97 in.21 10 ft 4.58 in. 39 19 ft 4.01 in. 75 37 ft 2.87 in.24 11 ft 10.49 in. 42 20 ft 9.92 in. 78 38 ft 8.78 in.27 13 ft 4.39 in. 48 23 ft 9.73 in. 90 44 ft 8.40 in.30 14 ft 10.30 in. 54 26 ft 9.54 in. 105 52 ft 1.92 in.WALL SHEET CAULKING DETAILInside view shown)IMPORTANT!ASSEMBLY DIRECTIONHORIZONTAL STRIPS OF CAULKINGARE USED TO SEAL GAP CAUSEDBY OVERLAP OF WALL SHEETS.LOCATE CAULKING AS SHOWN6”4”5/32” x 7/32” ROLLCAULKING (P/N) 193814APPLY AS SHOWN USING ACONTINUOUS STRIP4”6”SEE “WHERE USED” CHARTPage 22
