I-stand kufanele ifakwe ngaphambi kokuhlanganisa321Bailey Bridge.Indlela yokufaka imi kanje: Okokuqala, i-Bailey truss ihlangene edwaleni elisebhange lokuqalisa, futhi ingxenye eyodwa yengxenye ye-truss ibekwe edwaleni kanti enye ibekwe phezu kwezinkuni zesikhashana ze-cushion.
2.Iziphetho zamapuleti e-truss kufanele zihambisane.I-die beam kufanele ibekwe ngemuva kwebha eqondile yangaphambili. Imigqa emibili yezimbobo ezansi kohlaka kufanele ifakwe kumabhawudo epuleti le-chord eliphansi lamapuleti e-truss amabili ngokulandelanayo futhi iboshwe nge-clamp ye-beam.Ungaqinisi okwamanje, qinisa i-diagonal brace kugongolo ngemva kokufaka.
3.Faka izingcezu ezimbili ze-truss.Ngesikhathi esifanayo, i-Isiqephu seBaileykufanele ifakwe ku-truss yangaphambili ye-truss nge-brace diagonal, futhi ingemuva lenduku eqondile yangaphambili ye-truss emibili kufanele ifakwe nge-clamp ye-beam, futhi i-beam kufanele iqiniswe kahle ngaphandle kokuqinisa kuze kube yilapho i-diagonal brace emgodleni wesiphambano ifakiwe.
4.Faka i-truss enezigaba ezintathu, faka induku ye-wind tie ku-truss plate yesigaba sokuqala, faka i-diagonal brace ku-beam ye-truss plate enezigaba ezimbili, ukufakwa kohlaka lwekhala kufanele kujikelezwe ngokulandelana, futhi ipuleti le-truss elinezigaba ezine kufanele lifakwe kuhlaka lwekhala.
5.Enqubweni yokudonsa, umyalo obumbene, izinyathelo ezingaguquki kanye nokusebenza okuhlelekile kufanele kufinyelelwe.Ukusebenza kwe-roller nebhuloho kufanele kuhlolwe nganoma yisiphi isikhathi.Uma kutholakala noma yisiphi isimo, ukusebenza kufanele kumiswe ngokushesha futhi inkinga kufanele ixazululwe ngaphambi kokuqhubeka nokuqhubekela phambili.6.Ngemva kokuphusha ibhuloho endaweni, susa ifreyimu yekhala, vala i-chord engezansi yebhuloho esihlalweni, hlola ipuleti ye-Bailey, futhi uqinise zonke izisekelo, ukulungiswa kwemishayo kanye nezinduku zokubopha umoya.7.Ukubeka amapulangwe e-longitudinal njll.
