Nkhani - Ma H-beams Ogwira Ntchito Yomanga: Choyambitsa Chachikulu Cholimbikitsa Kukula kwa Makampani Abwino Kwambiri

mtengo wa h wopangidwa ndi galvanized ku China opanga

Posachedwapa, chifukwa cha kupita patsogolo kosalekeza kwa mizinda komanso kupititsa patsogolo ntchito zazikulu zomangamanga, kufunikira kwa zitsulo zomangira zogwira ntchito bwino kwawonjezeka. Pakati pa izi,Mzere wa H, monga gawo lofunika kwambiri lonyamula katundu m'mapulojekiti omanga, lakhala chinthu chofunikira kwambiri pakulimbikitsa chitukuko chapamwamba cha makampani omanga, ndi mawonekedwe ake abwino kwambiri amakina komanso njira zambiri zogwiritsira ntchito zomwe zikutsogolera njira yatsopano pamsika.

Mu pulojekiti yayikulu yokhala ndi nyumba zazitali ku East China, gulu la anthuCHIHEB 150 Miyendo ya HPosachedwapa yayikidwa mu kapangidwe ka nyumba yayikulu. Monga chitsanzo chodziwika bwino cha H-beam ku Europe, HEB 150 imakondedwa ndi mayunitsi omanga chifukwa cha kapangidwe kake koyenera ka magawo, kukana kupindika kwamphamvu komanso mphamvu yokhazikika yonyamula katundu. "Poyerekeza ndi magawo achitsulo achikhalidwe, HEB 150 imatha kuchepetsa kuchuluka kwa malo olumikizirana ndi 30% panthawi yomanga, kufupikitsa kwambiri nthawi yomanga ndikuwonetsetsa kuti nyumbayo ndi yotetezeka," adatero mainjiniya wamkulu wa polojekitiyi. Kugwiritsa ntchito kumeneku sikungotsimikizira phindu lenileni la zinthu zokhazikika za H-beam pomanga nyumba, komanso kumapereka chisonyezero chokwezera nyumba zokhazikika zachitsulo mumakampani.

Ngakhale kuti mitundu yokhazikika imagwiritsidwa ntchito kwambiri,zinthu za H-beam zogwira ntchito kwambiriakuimiridwa ndiMatanthwe a ASTM A572-50 Hakufulumizitsanso kulowa kwawo m'mapulojekiti ofunikira. Zikumveka kuti matabwa a ASTM A572-50 H ali ndi kulimba kwabwino kwambiri kutentha kochepa komanso kukana dzimbiri, ndipo mphamvu zawo zokolola zimatha kufika pa 345MPa, zomwe ndizofunikira kwambiri pama workshop akuluakulu, milatho yamisewu ndi mapulojekiti ena omwe ali ndi zofunikira kwambiri pakupanga. Pakadali pano, pomanga mlatho wodutsa mtsinje ku South China, matabwa a ASTM A572-50 H agwiritsidwa ntchito pakupanga truss yayikulu, kuthetsa vuto la kuthamanga kwa mphamvu ya bere pansi pa nyengo yovuta ndikuwonetsetsa kuti mlathowo ukugwira ntchito nthawi yayitali.

Kuphatikiza apo,Matabwa a flange a ASTM A572-50 osiyanasiyana, monga chinthu chochokera ku H-beam, chakulitsa kwambiri kuchuluka kwa ntchito ya H-beam mumakampani omanga. Ndi kukula kwake kwakukulu kwa flange, mtundu uwu wa flange ukhoza kugawa bwino katundu ndikukweza kukhazikika kwa kapangidwe kake. Wakhala ukugwiritsidwa ntchito kwambiri pomanga nyumba zazikulu zamalonda ndi mafakitale m'zaka zaposachedwa. Munthu woyang'anira kampani yopanga zitsulo anati: "Mu theka loyamba la chaka chino, kuchuluka kwa ASTM A572-50 wide flange beams kwawonjezeka ndi 40% chaka ndi chaka, ndipo zinthuzo zatumizidwanso kumisika ya Southeast Asia, kukhala malo atsopano okulira bizinesi yathu yotumiza kunja."

Akatswiri a zamakampani adanenanso kuti kukula mwachangu kwa H-beam yomanga sikungowonetsa kukweza kwa kufunikira kwa makampani omanga chitsulo chapamwamba, komanso kulimbikitsa luso laukadaulo la makampani omanga chitsulo. M'tsogolomu, ndi kupititsa patsogolo miyezo ya dziko lonse ya nyumba zobiriwira komanso zomangamanga zopanda mpweya wambiri, zinthu za H-beam zomwe zimagwira ntchito bwino kwambiri, kuteteza chilengedwe kwambiri komanso kusiyanasiyana kwambiri zidzakhala ndi gawo lofunika kwambiri pakulimbikitsa chitukuko chapamwamba cha makampani omanga.
