Cacisa Injongo kunye neeMfuno
Xa ukhethaIntsimbi ye-U-channel, umsebenzi wokuqala kukucacisa ukusetyenziswa kwawo kunye neemfuno eziphambili:
Oku kubandakanya ukubala ngokuchanekileyo okanye ukuvavanya ubukhulu bomthwalo ofunekayo ukumelana (umthwalo omileyo, umthwalo oguqukayo, impembelelo, njl.), omisela ngokuthe ngqo imilinganiselo kunye nemilinganiselo (ubude, ububanzi bomlenze, ubukhulu besinqe) kunye nebakala lamandla ezinto eziphathekayo; ukuqonda iimeko zokusetyenziswa kwayo (ezifana nezakhiwo zezakhiwo zemiqadi / ii-purlins, iifreyimu zoomatshini, izixhaso zomgca wokuhambisa, iishelufu okanye imihlobiso), iimeko ezahlukeneyo zigxininisa ngokwahlukileyo kumandla, ukuqina, ukuchaneka kunye nokubonakala; ngokuqwalasela imeko-bume yokusetyenziswa (ngaphakathi/ngaphandle, nokuba ifumile, imidiyadiya edlekayo), emisela iimfuno zokunqanda ukubola (ezifana ne-galvanizing yediphu eshushu, ukupeyinta) okanye nokuba i-weathering steel/stainless steel iyafuneka; ukucacisa indlela yokudibanisa (i-welding okanye i-bolting), eya kuchaphazela ukuyila komlenze (i-flat welding surface okanye imingxuma egciniweyo iyadingeka) kunye neemfuno ze-weldability eziphathekayo; ngexesha elifanayo, kuyimfuneko ukuqinisekisa izithintelo zobukhulu bendawo yokufakela (ubude, ubude, ububanzi) kunye nemimiselo ethile okanye imigangatho yoshishino ekufuneka iprojekthi ihambelane nayo ukuqinisekisa ukuba izinto ezikhethiweyo zihlangabezana nazo zonke iimfuno zokhuseleko kunye nokusebenza.
IiNkcazo zentsimbi yeSiteshi se-U, imilinganiselo kunye neMathiriyeli
1. Iinkcukacha
Umgangatho waseYurophuIsitishi se-UPNiimodeli zithiywe ngobude besinqe (iyunithi: mm). Banecandelo elinqamlezileyo elingu-U kunye neeparamitha eziphambili zibandakanya:
Ukuphakama kwesinqe (H): Ubude bubonke bejelo. Ngokomzekelo, ukuphakama kwesinqe se-UPN240 yi-240 mm.
Ububanzi bebhendi (B): Ububanzi beflange. Ngokomzekelo, i-UPN240 ine-85 mm band.
Ubukhulu besinqe (d): Ubukhulu bewebhu. Ngokomzekelo, i-UPN240 inobunzima besinqe se-9.5 mm.
Ubukhulu bebhendi (t): Ubukhulu beflange. Ngokomzekelo, i-UPN240 inobunzima bebhanti ye-13 mm.
Ubunzima bethiyori ngemitha: Ubunzima ngeyunithi yobude (kg/m). Ngokomzekelo, i-UPN240 inobunzima be-33.2 kg / m.
IiNkcazo eziQhelekileyo (IiModeli ezingaphelelanga):
| imodeli | Ubude besinqe (mm) | Ububanzi bomlenze (mm) | Ubunzima besinqe (mm) | Ubukhulu bomlenze (mm) | Ubunzima obuthiyori ngemitha (kg/m) |
| UPN80 | 80 | 45 | 6 | 8 | 8.64 |
| UPN100 | 100 | 50 | 6 | 8.5 | 10.6 |
| UPN120 | 120 | 55 | 7 | 9 | 13.4 |
| UPN200 | 200 | 75 | 8.5 | 11.5 | 25.3 |
| UPN240 | 240 | 85 | 9.5 | 13 | 33.2 |
| UPN300 | 300 | 100 | 10 | 16 | 46.2 |
| UPN350 | 350 | 100 | 14 | 16 | 60.5 |
2. Uhlobo lwezinto
Izinto zentsimbi zentsimbi ye-UPN kufuneka zihlangabezane nomgangatho waseYurophu EN 10025-2. Iinketho eziqhelekileyo ziquka:
(1) Izinto eziqhelekileyo
I-S235JR: Amandla okuvelisa ≥ 235MPa, ixabiso eliphantsi, elifanelekileyo kwizakhiwo ezimileyo (ezifana nokuxhaswa kokukhanya).
I-S275JR: Amandla okuvelisa ≥ 275MPa, amandla alinganayo kunye noqoqosho, asetyenziselwa izakhelo zokwakha ngokubanzi.
I-S355JR: Amandla okuvelisa ≥ 355MPa, ukhetho lokuqala lomthwalo ophezulu, olufanelekileyo kwiimeko ezixinzelelekileyo ezifana noomatshini bezibuko kunye nezixhaso zebhuloho. Amandla ayo okuqina afikelela kwi-470 ~ 630MPa, kwaye inobushushu obuhle obuphantsi.
(2) Izinto ezikhethekileyo
Intsimbi yamandla aphezulu: njenge-S420/S460, esetyenziselwa izixhobo zamandla enyukliya kunye neziseko zoomatshini abakhulu (ezifana ne-UPN350).
Intsimbi yemozulu: njenge-S355J0W, ixhathisa kwi-corrosion ye-atmospheric, ifanelekile kwiibhulorho zangaphandle.
Insimbi engagqwali: isetyenziswa kwindawo ezonakalisayo ezifana neekhemikhali kunye nolwandle, kodwa ngexabiso eliphezulu.
(3) Unyango lwangaphandle
Umnyama oshushu oshushu: umphezulu ongagqibekanga, ufuna unyango olulandelayo lokuchasana nomhlwa.
I-Hot-dip galvanizing: i-galvanized layer ≥ 60μm (efana nentsimbi yombhobho yokuxhasa igalari yombhobho), iphucula ukuxhathisa ukubola.
3. Iingcebiso zoKhetho
Iimeko zomthwalo ophezulu (ezifana ne-port crane rails): Beka phambili i-UPN300~UPN350 + S355JR izixhobo zokuqinisekisa ukugoba kunye nokuxhathisa ukucheba.
Indawo eyonakalisayo: Dibanisa nentsimbi yokuntywila eshushu okanye usebenzise ngokuthe ngqo intsimbi yemozulu.
Iimfuno ezilula: UPN80 ~ UPN120 uchungechunge (ubunzima beemitha 8.6 ~ 13.4kg / m), ezifanelekileyo kwiindonga zamakhethini kunye nezixhaso zepayipi.
Qaphela: Xa kuthengwa, kuyimfuneko ukuqinisekisa ingxelo yezinto (ngokuhambelana ne-EN 10025-2) kunye nokunyamezela kwe-dimensional (EN 10060) ukuqinisekisa ukuthotyelwa kweprojekthi.
