Silig bir ah oo prestressed waa silig bir ah oo tayadiisu sareyso oo laga sameeyay birta kaarboon-sare ee silig duuban oo kulul.Ka dib daaweynta kulaylka iyo habaynta qabow si loo buuxiyo shuruudaha xoojinta la taaban karo ee prestressed.Maaddada kaarboon ee siligga birta ah ee noocan ahi waa 0.65% ilaa 0.85%, iyo waxa ku jira baaruudka iyo fosfooraska labaduba waxay ka hooseeyaan 0.035%.Silig bir ah oo prestressed ayaa si warshadaysan loo soo saaray ilaa 1920-meeyadii.Tobannaan sano oo horumarineed ka dib, alaabooyin taxane ah oo ku habboon codsiyada kala duwan ayaa la soo saaray.
Marka loo eego aragtida qeexitaanka, xoogga xajinta ee siliga birta ee prestressed ayaa badanaa ka sarreeya 1470MPa.Sanadihii la soo dhaafay, heerka xooggu wuu iska bedelay inta badan 1470MPa iyo 1570MPa oo uu badiyay 1670~1860MPa.Dhexroorka siligga ayaa sidoo kale isbeddelay, min 3 ilaa 5 mm ilaa 5 ilaa 7 mm.Tilmaamahani waxay xaqiijinayaan adkeysiga iyo waxtarka agabka xoojiya dhismayaasha la taaban karo.
Qayb ka mid ah siligga prestressed waxaa ka mid ah silig qabow-jiiday, silig toosan oo dabcay, silig-nasasho yar, silig galvanized, iyo silig dhibceeyay.Kala duwanaanshahan ayaa bixiya astaamo kala duwan si loo daboolo baahiyaha kala duwan.Tusaale ahaan, silig bir ah oo qabow ayaa lagu yaqaanaa oogada siman iyo xoogga cufan ee sarreeya.Silig toosan oo dabcay ayaa bixiya dabacsanaan aad u fiican iyo qaybinta walbahaarka oo hagaagay.Silig-nasasho yar ayaa yaraysa luminta prespress.Siliga birta galvanized waa mid u adkaysta daxalka, halka siligga birta ee dhibcaha ahi ay kor u qaaddo ku dheggan shubka.
Tilmaamaha siligga birta ee prestressed ayaa ka dhigaya iyaga oo aad looga raadsado goobta dhismaha.Awoodeeda sare ee xajinta waxay hubisaa awoodda ay u leedahay in ay u adkeyso culeysyada culus iyo iska caabinta qallafsanaanta.Nidaamyada wax-soo-saarka saxda ah waxay xaqiijinayaan tayada iyo isku halaynta joogtada ah.Waxay leedahay fursado kala duwan oo la heli karo si ay ugu habboonaato shuruudaha mashruuc gaar ah.Siligga birta ah ee prestressed ayaa si weyn loogu isticmaalaa buundooyinka, dhismayaasha, jidadka tareenada, iyo dhismaha waddooyinka waaweyn.Codsigeedu wuxuu ka caawiyaa xoojinta dhismayaasha la taaban karo, kordhinta xooggooda iyo awoodda culeyska.
Kala duwanaanshiyaha iyo hantida sare awgeed, siligga birta hore loo hagaajiyay waxa uu noqday mid ka mid ah noocyada birta prespressed ee loogu isticmaalka badan yahay aduunka.Sanado badan, wax soo saarkeeda si isdaba joog ah ayaa loo kordhiyey si loo daboolo baahiyaha sii kordhaya ee warshadaha dhismaha.Iyadoo si joogto ah loo buuxinayo shuruudaha adag ee xoojinta shubka ee hore loo sii adkeeyey, siligga birta noocaan ah wuxuu sii wadaa inuu door muhiim ah ka ciyaaro hubinta badbaadada iyo adkeysiga kaabayaasha kala duwan ee adduunka.
