Taw qhia
Fabkis tso tawm NFA-35-035 "Kub-dip galvanized thiab zinc aluminium alloy prestressed steel hlau thiab steel stranded hlau". Tus qauv npog lub nominal txoj kab uas hla ntawm 5.0mm, 6.0mm, 7.0 hli thiab ncua kev kawm ntawv choj feem. Cov kev qhia tseem ceeb ntawm galvanized / zinc aluminium alloy coated steel hlau yog qhia nyob rau hauv lub rooj.
Cov qauv
Lawv muaj xws li load-bearing daim hlau, wedges thiab wedges. Ntxig cov leeg mus rau hauv lub thauj tog rau nkoj thiab tsav ib tug wedge rau hauv lub phaj phaj kom clamp cov leeg nyob rau hauv qhov chaw. Plane stress anchors muaj nyob rau hauv ntau configuration, xws li ib leeg-strand anchors rau ib tug steel bar thiab multi-strand anchors rau ntau tuav. Lawv yog ib qho tseem ceeb los xyuas kom meej qhov zoo ntawm kev hloov ntawm prestress mus rau lub pob zeb, muab cov qauv kev ncaj ncees uas yuav tsum tau rau daim ntawv thov.

Nta
Hlau hlau muab faib ua Class A thiab B. Class A steel hlau yog tsuas yog siv rau cov khoom prestressed nrog me me kev nyab xeeb thiab me me nyob load. Nws qaug zog tsis kam yuav tsum tau 0.70σb kev nyuaj siab txwv thiab 200 MPa.and 2 lab cycles. Class B steel hlau yog tsuas yog siv rau choj cables nrog loj kev nyab xeeb yam thiab loj nyob load. Nws qaug zog tsis kam yuav tsum tau 0.45σb nrog kev ntxhov siab amplitude ntawm 300 MPa thiab 2 lab cycles. Nyob rau tib lub sijhawm, tus qauv kuj tau teev cov naj npawb ntawm kev rov khoov ntawm cov hlau los kuaj cov yas ntawm cov hlau.
Qhov zoo
Choj cable yog lub neej ntawm ib tug loj-span ncua choj los yog cable-nyob choj hla hiav txwv thiab dej. Kev tiv thaiv corrosion ntawm nws cov hlau hlau yog qhov tseem ceeb heev rau kev ua haujlwm ntev thiab kev nyab xeeb ntawm cov qauv. Tus qauv faib cov txheej txheem ntawm cov hlau hlau ua plaub pawg:
(1) qhov zoo ntawm cov txheej hauv ib cheeb tsam ntawm cov hlau hlau;
(2) lub zog txuas ntawm txheej;
(3) qhov txuas ntxiv ntawm txheej txheej; thiab
(4) lwm yam. Tus txheej txheem yuav tsum tau hais tias qhov zoo ntawm txheej txheej ntawm ib chav tsev ntawm cov hlau hlau yuav tsum yog 180 ~ 350 g / m2, qhov ceev ntawm txheej yog xam raws li 7.2 g / cm3, thiab lub thickness ntawm txheej yuav tsum yog 26 ~ 49m ua. Txoj kev tshuaj xyuas qhov zoo ntawm cov hlau hlau txheej ib square meter yuav tsum yog NF EN1460, thiab qhov ntev ntawm cov qauv xeem yuav tsum tsis pub tsawg tshaj 150 mm.Cov polyethylene Covered nyob cable / Galvanized parallel hlau cable yog tsim los ntawm twisting siab zog galvanized steel hlau thiab tom qab ntawd txheej cov xov hlau sib tw nrog high-density polyethylene nrog cov txheej txheem kub extrusion. Nws yog dav siv raws li cable rau cable nyob choj, khi-down cable, hanger rau orch choj, suspender rau ncua kev kawm ntawv choj thiab cable rau tshwj xeeb struduer.
Cable ntawm cua-los nag vibration suppression
Lub nyob Cable yog ib qho tseem ceeb ntawm Cable-nyob nrog lawv qhov ntev npaum li cas nce ntxiv.Qhov kev sib tw tau nce lub neej ua haujlwm thiab muab ntxiv kev nyab xeeb.
Cable nrog ob helical hlau
Ob chav helical nyob ntawm qhov chaw nyob cable nrog qhov siab thiab qhov siab tiv thaiv kom tsis txhob muaj cua daj cua dub ua rau muaj kev vibration.Qhov kev siv tshuab no tau ua tiav rau cov haujlwm choj, xws li Edong Yangtze River Choj, Shenzhen Bay Choj, Indonesia Suramadu Choj, Jinan Jianbang Choj. thiab sai sai.
Ultra siab zog ruaj cable
Raws li kev nyob ib puag ncig cable, lub ultra-high-lub zog ruaj khov (qib zog mus txog 1770MPa, 1860MPa thiab 1960Mpa) cable tau txuas ntxiv nws yog kev pab cuam lub neej tshaj 50-xyoo nyob rau hauv ib txwm mob los ntawm kev siv raw khoom zoo dua, txhim kho kev tsim khoom. thiab cable qauv.
lt tau siv rau ntawm Sutong Choj, Hong Kong Stonecutters Choj, Zhujiang Huangpu Choj, Jiashao Choj, HongKong-Zhuhai-Macau Choj thiab lwm yam.
Ultra ntev thiab loj cable
Nrog rau kev tsim kho ntawm cable-nyob txuas hniav nrog nws lub ntsiab ncua ntev tshaj 100m, qhov yuav tsum tau nyob rau hauv cable ua siab dua thiab siab dua nyob rau hauv ntev thiab kev ua tau zoo.Tam sim no, peb lub tuam txhab muaj peev xwm tsim ultra-ntev thiab loj nyob cable nrog ntev tshaj 800m thiab qhov loj tshaj plaws tuaj yeem ncav cuag 511p7.Peb yog cov chaw tsim khoom lag luam nkaus xwb uas muaj peev xwm tsim cable ntev dua 500m.
