SNE~T 3 op ¢ <br />-~- <br />"^ <br />10. Continue placing spacers and stringers, but do not <br />tighten nuts. <br />11. Tighten all oolts, chec}: alignment of wall, and resume <br />bac}:filling. Repeat steps where necessary. <br />12. Add vertical connector splices and vertical connectors <br />for the next lift. (dote that connecting channels are <br />also attached with these same bolts.) <br />13. Repeat steps 10 and 11 as necessary. <br />14. Finish off top of bins by installing stringer stiffeners <br />ar,d column caps. <br />15. Complete backfilling. <br />C. Alternate Method of Assembly <br />ltihen a crane is available, a fast and economical method of <br />erection is to sub-assemble the transverse section. P1est of <br />the bolting is downhand and therefore faster whether hand or <br />• power wrenches are used. <br />~y Two or more saw horses with a pair of timbers i:ill make an <br />adequate assembly table. The required number of spacers <br />are laid on the table and eertieal connector splices (if <br />used) and vertical connectors are slipped over the ends of <br />the spacers. The connecting channels are ther. laid in place <br />and the entire section bolted tight. Ee sure that the <br />vertical connecters are parallel before the bolts are <br />tightened. <br />These assemblies are set on positioned grade plates and 'Held <br />in place bl• stringers at the bottom and stringers or stringer <br />stiffener at the top. Chec}: alignment of wall and tighten <br />these bolts. The rest of the stringers are then bolted in <br />place as suggested in steps 5, 9 and 10 in 6 above. <br />D. General <br />Hundreds of Armco walls have been assembled with hand tools <br />and common labor. Power tools, lifting equipr.,ent, and <br />skilled labor will in many cases decrease construction time <br />and make the r:ork easier. Ko mention is made here of <br />excavating, backfilling, or general earth moving equipment, <br />as that's a field of it's own. <br />• <br />A <br />~. <br />
