Prestressed steel wire ndi chinthu chosunthika komanso chofunikira pantchito yomanga.Wopangidwa kuchokera ku waya wapamwamba kwambiri wa carbon zitsulo zotentha zotentha zomwe zimatenthedwa ndi kutentha ndi kuzizira, mawayawa amapangidwa mwapadera kuti akwaniritse zofunikira zolimbitsa konkire.Waya wachitsulo uli ndi mpweya wa 0.65% mpaka 0.85%, sulfure ndi phosphorous zomwe zili pansi pa 0.035%, ndipo zimakhala ndi mphamvu zabwino komanso zolimba.
Waya wachitsulo wopindika wapita patsogolo kwambiri kuyambira pomwe adapanga mafakitale ndikugwiritsa ntchito m'ma 1920s.Masiku ano, mitundu yosiyanasiyana yazinthu zoyenera kugwiritsidwa ntchito mosiyanasiyana komanso yokhala ndi mawonekedwe osiyanasiyana apangidwa.Izi zikuphatikizapo waya wozizira, waya wowongoka, waya wopumula pang'ono, waya wamalata ndi waya wogoletsa.Zogulitsa izi, kuphatikiza ndi zingwe zachitsulo zokhazikika, zakhala mitundu yachitsulo yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi.
Kufikira m'magulu, waya wa PC wocheperako ndi chisankho chodziwika bwino.Mphamvu yake yabwino kwambiri yokhazikika imapangitsa kuti ikhale yabwino pamapulogalamu opanikizika kwambiri.Kuphatikiza apo, makulidwe a waya wachitsulo ndi 2.64 mm, ndikupangitsa kuti ikhale yoyenera ntchito zomanga zosiyanasiyana.Kuphatikiza apo, waya wa konkriti wotsindikitsidwa uyu amagwirizana ndi miyezo yofotokozedwa mu 1084 SAEJ403, kuwonetsetsa kuti ndi yodalirika komanso yodalirika.
Chimodzi mwazinthu zodziwika bwino za waya wachitsulo wokhazikika ndi mphamvu yake yokhazikika.Nthawi zambiri, mphamvu yamanjenje yamtundu uwu wa waya wachitsulo imakhala pamwamba pa 1470MPa, pang'onopang'ono ikusintha kupita kumlingo waukulu wa 1670 ~ 1860MPa.Kuphatikiza apo, kukula kwa waya kwasinthanso pakapita nthawi, kuchokera ku 3 mpaka 5 mm mpaka pano 5 mpaka 7 mm.Kuchuluka kwamphamvu kumeneku ndi mainchesi akulu kumapangitsa waya wokhazikika kukhala wotanuka kwambiri komanso wokhoza kupirira katundu wamkulu.
Chifukwa cha zinthu zake zabwino kwambiri, waya wachitsulo wa prestressed amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana omanga.Nthawi zambiri amagwiritsidwa ntchito kulimbikitsa zomanga monga milatho, nyumba ndi njanji zanjanji kuti apititse patsogolo mphamvu zawo zonyamula katundu komanso kukhulupirika kwathunthu.Magawo a mafakitale ndi zomangamanga amadalira kwambiri waya wachitsulo wokhazikika kuti atsimikizire kuti moyo wautali ndi chitetezo cha ntchito zawo.
Mwachidule, chitukuko cha prestressed steel waya chinasintha ntchito yomanga.Kuphatikizika kwazitsulo zapamwamba za carbon ndi njira zamakono zopangira makina kumapangitsa kuti pakhale mitundu yambiri yazinthu zoyenera kugwiritsa ntchito zosiyanasiyana.Ndi mitundu yambiri yamagulu ndi zosankha za kukula, komanso mphamvu zabwino kwambiri zogwirira ntchito komanso ntchito zambiri, waya wachitsulo wa prestressed amakhalabe chigawo chofunikira pa zomangamanga zamakono.
Kugwiritsa ntchito
Monga China zitsulo makampani kutsogolera mabizinezi, dziko zitsulo malonda ndi katundu "Hundred chikhulupiriro chabwino ogwira ntchito", China zitsulo malonda mabizinezi, "Top 100 mabizinezi wamba ku Shanghai". ) imatenga "Kukhulupirika, Kuchita, Kupanga Zinthu, Win-Win" monga mfundo yake yokhayo yogwiritsira ntchito, nthawi zonse amalimbikira kuika zofuna za makasitomala poyamba.
