Le phrojekthi iwuhlaka lwesikhala esiyindilinga / ukuphakama okungamamitha angama-44.55 / ubude obuphelele 332 amamitha / ingqikithi ye-span 77.2 amamitha.
1. Wonke ama-purlin angenhla angama-hot-dip galvanized steel purlins angama-rectangular, inani elifaka uthayela ngu-250~275g/m, kanti okokusebenza yi-Q235B.
2. Ubukhulu bendawo budinga ukubhekwa ngaphambi kokwakhiwa kwesakhiwo.
3. Okunye okungashiwongo kuzohambisana namazinga kazwelonke amanje.
4. Ukulandelana kokufakwa yilokhu: ukuthwala ibhola - ibhola lezintambo ezingezansi, induku - induku yesisu - ibhola lentambo ephezulu, induku.
Insimbi: Ngaphandle kwalapho kuchazwe ngenye indlela, wonke amapayipi ensimbi enziwe ngensimbi ye-Q235B.Ukwakheka kwamakhemikhali ayo kanye nezakhiwo zokuwumshini kuzohambisana nezinhlinzeko zendinganiso yamanje "ye-Carbon Structural Steel" (GB/T700-2006).Amandla aqinile, ubude, iphuzu lesivuno, ukuhlolwa okugoba okubandayo kanye nokuqina komthelela wento kufanele kuqinisekiswe ukuthi kuyafaneleka, futhi okuqukethwe kwesibabule, i-phosphorus nekhabhoni kufanele kuqinisekiswe ukuhlangabezana nezidingo.Ukubekezelela ukujiya kwepuleti lensimbi kuzohlangabezana nezimfuneko zokusebenza kokuzamazama komhlaba kwensimbi kokuthi "Ubukhulu, Imimo, Isisindo Nokubekezelelwa Kwamapuleti Nemicu Yensimbi Egoqwe Okushisayo":
1) Isilinganiso senani elilinganisiwe lamandla esivuno sensimbi kuya kunani elilinganisiwe lamandla okuqina akufanele libe likhulu kuno-0.85;
2) Insimbi kufanele ibe nezinyathelo ezicacile zokukhiqiza, futhi ukuphakama akufanele kube ngaphansi kuka-20%;
3) Insimbi kufanele ibe nokushisela okuhle kanye nokuqina komthelela ofanelekayo.
