Waya wazitsulo wa konkriti wokhazikika ndi waya wachitsulo wapamwamba kwambiri wopangidwa kuchokera ku ndodo za waya zotentha za carbon steel, zomwe zimatenthedwa ndi kutentha komanso kuzizira.Zapangidwa mwapadera kuti zikwaniritse zofunikira za prestressed konkriti reinforcement.
Kulimba kwamphamvu kwa waya wachitsulo wa konkriti wokhazikika nthawi zambiri kumakhala pamwamba pa 1470MPa.Popita nthawi, kuchuluka kwamphamvu kwasintha kuchokera ku 1470MPa ndi 1570MPa kupita kumitundu yodziwika bwino ya 1670MPa kupita ku 1860MPa.Waya awiri asinthanso, kuchokera koyambirira 3 ~ 5mm mpaka muyezo wapano wa 5 ~ 7mm.Izi zimatsimikizira kulimba ndi kudalirika kwa waya wachitsulo polimbana ndi kupsinjika ndi katundu wofunikira wa zomangira za konkire.
Mpweya wa carbon wa mtundu uwu wa waya wachitsulo ndi 0,65% mpaka 0.85%, ndipo sulfure ndi phosphorous zili pansi, zonse pansi pa 0.035%.Chiyambireni kupanga ndikugwiritsa ntchito mafakitale m'zaka za m'ma 1920, waya wachitsulo wopangidwa ndi prestressed wakhala zaka zambiri zachitukuko, zomwe zimapangitsa kuti pakhale mitundu yambiri yazinthu zoyenera kugwiritsa ntchito zosiyanasiyana.Izi ndi monga waya wokokedwa ozizira, waya wowongoka ndi wotenthedwa, waya wopumula pang'ono, waya wamalata ndi waya wogoletsa.Mawaya achitsulo oponderezedwa ndi zingwe zachitsulo zopangidwa kuchokera kwa iwo zakhala mitundu yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi.
Waya wokhazikika wa konkriti uli ndi zinthu zingapo zofunika zomwe zimapangitsa kuti zikhale zoyenera kulimbitsa zomanga za konkriti.Kulimba kwake kwamphamvu komanso kukana kusinthika kumatsimikizira kuti imatha kupirira katundu wofunikira ndikusunga umphumphu wamapangidwe.Kuonjezera apo, zochepetsera zochepa za mitundu ina ya waya wa prestressing zimachepetsa kutayika kwa zovuta pakapita nthawi.Izi zimathandiza kuti konkire ikhale yokhazikika.Mitundu yosiyanasiyana yamawaya, monga malata ndi zigoli, imapereka zina zowonjezera monga kukhazikika kwa dzimbiri kapena kulimba kwa ma bond.
Mawaya a konkire osindikizidwa amagawidwa m'mitundu yosiyanasiyana kutengera mawonekedwe awo ndi ntchito zawo.Izi zikuphatikiza waya wopumula pang'ono wa PC, womwe umathandizira kusamutsa kupsinjika ndikuchepetsa mawonekedwe opumula.Gulu lina limatengera kukula kwa waya, ndi zosankha zoyambira 2.64mm kuti zigwiritsidwe ntchito mosavutikira mpaka ma diameter akulu pantchito zomanga zolemera.
Waya wa konkriti wokhazikika amagwiritsidwa ntchito kwambiri pantchito zomanga zosiyanasiyana.Amagwiritsidwa ntchito makamaka pomanga milatho, ma viaducts, nyumba zazitali ndi zina zazikulu zomwe zimafuna kupititsa patsogolo kunyamula katundu.Kutha kwa waya kupirira kupsinjika komanso kukana kupsinjika kumapangitsa kukhala koyenera kulimbikitsa mamembala a konkire.Amagwiritsidwanso ntchito popanga zinthu za precast konkriti, makina okhazikika pambuyo pake, ndi makina okhazikika pansi pomwe zida zodalirika komanso zolimba zimafunikira.M'malo mwake, mawaya a konkriti okhazikika ndi ofunikira kwambiri pakuwonetsetsa mphamvu zamapangidwe komanso moyo wautali wamitundu yosiyanasiyana ya konkriti.
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.
