Cacisa Inhloso Nezidingo
Uma ukhethaInsimbi yesiteshi se-U, umsebenzi wokuqala ukucacisa ukusetshenziswa kwayo okuqondile kanye nezidingo eziyinhloko:
Lokhu kuhlanganisa ukubala noma ukuhlola ngokunembile umthwalo omkhulu okudingeka uwubekezelele (umthwalo omile, umthwalo oguquguqukayo, umthelela, njll.), okunquma ngqo imininingwane nobukhulu (ukuphakama, ububanzi bomlenze, ukujiya kwesinqe) kanye nezinga lamandla ezinto zokwakha; ukuqonda izimo zokusetshenziswa kwayo (njengemishayo/ama-purlin esakhiwo sokwakha, ozimele bemishini, izisekelo zomugqa wokuhambisa, amashalofu noma imihlobiso), izimo ezahlukene zigcizelela amandla, ukuqina, ukunemba kanye nokubukeka; uma ucabangela indawo yokusetshenziswa (ngaphakathi/ngaphandle, kungakhathaliseki ukuthi inomswakama, imithombo ebolile), enquma izidingo zokulwa nokugqwala (njengokushisa okushisayo, ukupenda) noma ukuthi insimbi/insimbi engagqwali iyadingeka yini; ukucacisa indlela yokuxhuma (ukuwelda noma ukubhoboza), okuzothinta ukwakheka komlenze (kudingeka indawo yokuwelda eyisicaba noma imigodi egciniwe) kanye nezidingo zokuwelda kwezinto; ngesikhathi esifanayo, kuyadingeka ukuqinisekisa imikhawulo yosayizi wendawo yokufaka (ubude, ukuphakama, ububanzi) kanye nemithethonqubo ethile noma amazinga embonini okumele iphrojekthi iwalandele ukuqinisekisa ukuthi izinto ezikhethiwe ziyahlangabezana nazo zonke izidingo zokuphepha nokusebenza.
Imininingwane Yensimbi Yesiteshi Se-U, Ubukhulu kanye Nezinto Ezisetshenziswayo
1. Imininingwane
Izinga laseYurophuIsiteshi se-UPNAmamodeli aqanjwe ngokuphakama kwawo okhalweni (iyunithi: mm). Anesigaba esinqunyiwe esimise okwe-U futhi amapharamitha abalulekile afaka:
Ukuphakama kwesinqe (H): Ukuphakama kwesinqe sekukonke. Isibonelo, ukuphakama kwesinqe kwe-UPN240 kungu-240 mm.
Ububanzi bebhendi (B): Ububanzi beflengi. Isibonelo, i-UPN240 inebhendi engu-85 mm.
Ubukhulu besinqe (d): Ubukhulu bewebhu. Isibonelo, i-UPN240 inobukhulu besinqe obungu-9.5 mm.
Ubukhulu bebhendi (t): Ubukhulu beflange. Isibonelo, i-UPN240 inobukhulu bebhendi obungu-13 mm.
Isisindo sethiyori ngemitha: Isisindo ngeyunithi ubude (kg/m). Isibonelo, i-UPN240 inesisindo esingu-33.2 kg/m.
Imininingwane Ejwayelekile (Amamodeli Angaphelele):
| imodeli | Ukuphakama kwesinqe (mm) | Ububanzi bomlenze (mm) | Ubukhulu besinqe (mm) | Ubukhulu bomlenze (mm) | Isisindo sethiyori ngemitha (kg/m2) |
| I-UPN80 | 80 | 45 | 6 | 8 | 8.64 |
| I-UPN100 | 100 | 50 | 6 | 8.5 | 10.6 |
| I-UPN120 | 120 | 55 | 7 | 9 | 13.4 |
| I-UPN200 | 200 | 75 | 8.5 | 11.5 | 25.3 |
| I-UPN240 | 240 | 85 | 9.5 | 13 | 33.2 |
| I-UPN300 | 300 | 100 | 10 | 16 | 46.2 |
| I-UPN350 | 350 | 100 | 14 | 16 | 60.5 |
2. Uhlobo lwezinto
Izinto zensimbi zesiteshi se-UPN kumele zihlangabezane nezinga laseYurophu i-EN 10025-2. Izinketho ezivamile zifaka:
(1) Izinto ezivamile
I-S235JR: Amandla okukhiqiza ≥ 235MPa, izindleko eziphansi, ezifanele izakhiwo ezimile (njengezisekeli zokukhanya).
S275JR: Amandla okukhiqiza ≥ 275MPa, amandla alinganiselayo kanye nokonga, asetshenziselwa ozimele besakhiwo abavamile.
I-S355JR: Amandla okukhiqiza ≥ 355MPa, ukukhetha kokuqala komthwalo ophezulu, kufanelekile ezimweni zokucindezeleka okuphezulu njengemishini yechweba kanye nezisekelo zamabhuloho. Amandla ayo okudonsa afinyelela ku-470 ~ 630MPa, futhi inokuqina okuhle kwezinga lokushisa eliphansi.
(2) Izinto ezikhethekile
Insimbi enamandla amakhulu: njenge-S420/S460, esetshenziselwa imishini yamandla enuzi kanye nezisekelo zemishini esindayo kakhulu (njenge-UPN350).
Insimbi eshintshashintshayo: njenge-S355J0W, emelana nokugqwala komoya, efanelekile kumabhuloho angaphandle.
Insimbi engagqwali: isetshenziswa ezindaweni ezigqwalisayo njengamakhemikhali kanye nezasolwandle, kodwa ngezindleko eziphakeme.
(3) Ukwelashwa kwendawo
Umnyama ogoqekile oshisayo: ubuso obuzenzakalelayo, obudinga ukwelashwa okulandelayo kokulwa nokugqwala.
I-hot-dip galvanizing: ungqimba lwe-galvanized ≥ 60μm (njengensimbi yesiteshi yezisekeli zegalari yamapayipi), ithuthukisa ukumelana nokugqwala.
3. Izincomo zokukhetha
Izimo ezithwala umthwalo omningi (njengezitimela ze-port crane): Beka phambili izinto ze-UPN300~UPN350 + S355JR ukuqinisekisa ukumelana nokugoba nokusika.
Indawo ebhubhisayo: Hlanganisa ne-hot-dip galvanizing noma sebenzisa insimbi eshintshashintshayo ngqo.
Izidingo ezilula: Uchungechunge lwe-UPN80~UPN120 (isisindo samamitha angu-8.6~13.4kg/m), lufanelekela izikhonkwane zodonga lwekhethini kanye nezisekelo zamapayipi.
Qaphela: Uma uthenga, kuyadingeka ukuqinisekisa umbiko wezinto ezibonakalayo (ngokuvumelana ne-EN 10025-2) kanye nokubekezelelana kobukhulu (EN 10060) ukuqinisekisa ukuhambisana kwephrojekthi.
Izincomo Zomkhiqizi Wesiteshi Se-U Esithembekile-Iqembu Lasebukhosini
At Iqembu Lasebukhosini, singabalingani abaphambili emkhakheni wokuhweba ngezinto zensimbi zezimboni zaseTianjin. Ngobungcweti nokuzibophezela ekubekeni phambili ikhwalithi, asizibekile nje kuphela ensimbini enomumo we-U, kodwa nakweminye imikhiqizo yethu.
Yonke imikhiqizo enikezwa yiRoyal Group idlula enkambisweni yokuhlola ikhwalithi eqinile ukuqinisekisa ukuthi ihlangabezana noma idlula amazinga ekhwalithi aphezulu. Lokhu kusisiza ukuthi sinikeze amakhasimende ethu imikhiqizo ethembekile nephephile efanele ukusetshenziswa okuhlukahlukene.
Siyaqonda ukuthi isikhathi sibaluleke kakhulu kumakhasimende ethu, ngakho-ke, abasebenzi bethu kanye nezimoto eziningi bahlala bekulungele ukuletha izimpahla. Ngokuqinisekisa isivinini kanye nokugcina isikhathi, sisiza amakhasimende ethu ukuba onge isikhathi futhi enze ngcono izinqubo zawo zokwakha.
I-Royal Group ayigcini nje ngokulethela ukuzethemba ngekhwalithi yomkhiqizo kanye nenani, kodwa futhi ikhombisa ubuqotho ebudlelwaneni bethu namakhasimende. Asinikezi nje kuphela izinhlobo ezahlukene zensimbi enomumo we-U, kodwa futhi sihlinzeka ngemikhiqizo eminingi, njengensimbi enomumo we-H, insimbi enomumo we-I, kanye nensimbi enomumo we-C, ukuze kuhlangatshezwane nezidingo ezahlukahlukene zamakhasimende ezweni lonke.
Yonke i-oda efakwe kwiRoyal Group iyahlolwa ngaphambi kokukhokha. Amakhasimende anelungelo lokuhlola imikhiqizo yawo ngaphambi kokukhokha ukuqinisekisa ukwaneliseka kanye nekhwalithi yomkhiqizo.
