Njengoko imakethi yeziseko zophuhliso zehlabathi iza kulawulwa “kukunciphisa ubunzima” kunye “nokunciphisa i-carbonization” ngo-2026, abakhi bezakhiwo kunye nabaphathi bokuthenga bajongene nesigqibo esibalulekileyo kwiiprojekthi zesakhiwo sentsimbi: ii-C-purlins okanyeIitshaneli ze-C?
Nangona zifana, inkqubo yokuvelisa, iimpawu zoomatshini, kunye neemeko zokusetyenziswa kwezi profayili zimbini zichaphazela ngokuthe ngqo ukhuseleko kunye noqoqosho lwalo naliphi na iprojekthi. Nantsi uthelekiso lwetekhnoloji esisiseko icandelo lokwakha elifuna ukuyiqonda ngo-2026.
1. Inkqubo yokuvelisa: Eyenziwe ngobushushu okanye ebandayo
Lo ngumahluko ophambili phakathi kwezi profayili zimbini:
- I-C Purlin: Yenziwe kusetyenziswa imicu yentsimbi egqunyiweyo ekumgangatho ophezulu ngendlela echanekileyo yokwenza ubushushu. Ngokwesiqhelo ineendonga ezibhityileyo (1.6mm ukuya kwi-3.2mm) kwaye ine "milebe" yokuphucula ukuqina kwesakhiwo ngelixa ihlala ilula.
- Itshaneli ye-C: Intsimbi yolwakhiwo egoqwe ngoomatshini. Inobukhulu bodonga obuqhele ukugqitha i-5mm, nto leyo eyenza ukuba ibe yiprofayili enzima engenamilebe. Yinto ephambili "yokwakha ifreyimu ephambili" enamandla amakhulu kwimizi-mveliso.
2. Umthamo wokuthwala umthwalo kunye nokusebenza kwe-Span
Ngexesha loyilo lwedijithali loyilo lwezakhiwo luka-2026, izibalo ezithwala umthwalo ziye zachaneka ngakumbi:
- I-C Purlin: Yenzelwe ngokukodwa imithwalo esasazekileyo. Ilungele ukudlulisa uxinzelelo lophahla kunye nephaneli yodonga kwisakhelo sentsimbi esiphambili. Nangona kunjalo, phantsi kwemithwalo emikhulu, ukuqina kwayo okujikelezayo kuphantsi.
- Itshaneli ye-C: Inika amandla amakhulu okuthwala imithwalo emide kunye nokuqina kwe-flexural. Ihlala isetyenziswa njenge-beam okanye ikholamu ye-short-to-medium spans, ekwaziyo ukuthwala imithwalo emikhulu yomxhuzulane ngaphandle kokubambelela kwindawo ethile.
3. Imephu yeSicelo soKwakha sika-2026
| Imeko yesicelo | Imveliso Ecetyiswayo | Isizathu |
|---|---|---|
| Iivenkile ezinkulu zeLogistics | C Purlin | Uyilo olulula lunciphisa ukusetyenziswa kwentsimbi iyonke; ugqubuthelo lwe-galvanized lubonelela ngokhuseleko lweminyaka engaphezu kwama-20. |
| Izixhaso zoMgangatho onemigangatho emininzi | Itshaneli ye-C | Ubukhulu obukhulu bubonelela ngenkxaso eqinileyo ethe nkqo kwiinkqubo zomgangatho onzima. |
| Iiraki ze-PV zelanga | C Purlin | Ukulungiswa okuguquguqukayo; imingxunya ebhoboziweyo kwangaphambili inciphisa kakhulu ixesha lokufakwa kwindawo. |
| Iifreyimu zezixhobo zoshishino | Itshaneli ye-C | Isakhiwo esizinzileyo esisebenza kakuhle kakhulu nge-welding kunye nokumelana nokungcangcazela okuphezulu. |
4. Uhlalutyo lweNdleko kunye nokuSebenza kakuhle koLwakhiwo
Idatha yemarike yowama-2026 ibonisa ukuba ukunyuka kweendleko zabasebenzi kwenze ukuba ukulula kokufakela kube yinto ebalulekileyo.
- Isantya soFakelo: IiC Purlins zihlala zibholwa kwangaphambili kwaye zihlanganiswe ngeebholiti, okwenza ulwakhiwo lube ngaphezulu kwama-30% ngokukhawuleza kuneC Channels, ezihlala zifuna ukuwelda okunzima.
- Iindleko zeLogistics: Ekubeni iiC Purlins zinobunzima obuyi-1/3 ukuya kwi-1/2 kuphela kwiiC Channels, zibonelela ngenzuzo enkulu yokuthutha impahla kurhwebo lwamazwe ngamazwe, zivumela abathengi ukuba bandise indawo yeekhonteyina.
Kwiiprojekthi zika-2026 ezibeka phambili isantya kunye nokunciphisa ubunzima (njengeefama zelanga kunye neendawo zokugcina izinto), i-C Purlin yeyona ndlela ibalaseleyo. Nangona kunjalo, kwiifreyimu zemizi-mveliso ezinzima kunye neenkxaso ezinamabala amaninzi, i-C Channel yendabuko ihlala iyindlela esemgangathweni yoshishino yokuqina kunye namandla.
