Kulul - Galvanized Steel Strand Prestressed
Hordhac Product
Galvanized Hot-Dipped PC Strand nasashada hooseeysa ee xarig bir ah oo prestressed ayaa ka kooban todobo fiilo bir wareeg ah oo kulul la rusheeyey lehna iska caabin daxalka wanaagsan, kaas oo si wax ku ool ah u kordhin kara nolosha qaybaha gobolka ee deegaanka daxalka ah sida meelaha xeebaha, kuwaas oo loo aqoonsan yahay sida nooc wax ku ool ah oo ka hortagga daxalka hadda iyo caalamkaba.
Heerkani waa mid lagu dabaqi karo fiilada buundada, qaybaha xiisadda go'an, kor u qaadista ama hagaajinta qaybaha xiisadaha dhismayaasha iyo dhismayaasha kale ee prestressed, kuwaas oo aan si toos ah loogu isticmaalin dhismayaasha grouting la taaban karo, dhexroor: 12.7mm, 15.mm, 15.7mm, 17.8mm, xoog fasalka: 1770MPa, 1860 MPa, 1960MPa. (Hadda ka dib waxaa loo yaqaan "seedka birta").
Qaab dhismeedka 1x7, 1x19 kulul-madow galvanized galvanized prestressed taxane taxane ah, xoogga korriin kaas oo gaari kara 1860MPa iyo qeexitaan la mid ah sida cad & wareega PC strand strand marka la eego heerka waxqabadka acc.to GB/T 33363, ASTM A416, EN10138, BS5896 iyo NFA35-035 iwm.
Tilmaamaha Alaabta
Badeecada waxaa la soo saari karaa iyadoo la raacayo codsiyada daahan zinc ee macaamiisha, daahan zinc wuxuu gaari karaa ilaa 250 gsm ama ka badan, lebiska lakabka daahan zinc waa 3-4 jeer iyada oo aan soo bandhigin naxaas, iyo adhesion ma jabo oo ma dilo marka la eego xaalada adigoo dabaylaha 8 wareegyada ka dib marka la dahaadho zinc .
Iyada oo ku xidhan qalabka horumarsan ee shirkadda, waxaan naqshadeyn karnaa habka galvanized si loo daboolo shuruudaha gaarka ah ee isticmaalayaasha tayada lakabka zinc, tayada dusha, iwm.
Marka la barbar dhigo xadhig birta PC ah oo aan lahayn daahan iyo xadhig birta PC galvanized, kii hore wuxuu u muuqday miridh cas ka dib tijaabada buufinta milixda ee 24 saacadood.
Tusaalaha isbeddelada xadhig birta PC ah oo aan lahayn daahan iyo xadhig birta PC galvanized ka dib 21 maalmood oo tijaabo ah buufin milix dhexdhexaad ah sida soo socota,
Codsiyada Alaabta
1) Alaabooyinka waxaa loo isticmaali karaa injineernimada dhismaha iyo miinada dhuxusha ee taageerada wadooyinka ee xaaladaha deegaanka ee adag.
2) Sanadihii ugu dambeeyay, waxaa sidoo kale lagu dabaqay goobta tamarta dabaysha. "1x7-dhexdhexaad 21.6mm, Large-Sized Hot-Dipped Galvanized PC Steel Strand", kaas oo lagu dabaqay adduunka ugu horreeya "160m, dabaysha-xawaaraha hoose ee munaaradda marawaxadaha dabaysha" iska caabinta dabaysha ee munaaradda. Iyada oo iska caabin daxalka wanaagsan, kaas oo kordhin kara nolosha adeegga munaaradda.
Taawarka sare ee tijaabada ah ee 160m ee ugu horreeya adduunka ee xawaaraha dabaysha hoose ee Shandong
