Intambo yensimbi ebilisiwe ngokuvamile ibhekisela ocingweni oluyinhloko noma ilungu lamandla le-messenger wire (i-guy wire).
A. I-strand yensimbi ihlukaniswe yaba izinhlobo ezine ngokusho kwesakhiwo sesigaba.
Kuboniswa njengesakhiwo esingezansi
I-B. GB steel strand ihlukaniswe ngamamaki amahlanu ngokuya ngamandla okuzisholo: 1270MPa, 1370MPa, 1470MPa, 1570MPa, 1670MPa.
C. Ngogqinsi oluhlukene longqimba lwezinki emucu wensimbi, ungqimba lwezinc lwentambo yensimbi ku-GB steel strand luhlukaniswe ngamaleveli amathathu: A, B kanye no-C.
1. Ukusetshenziswa kwe-steel strand
I-coating ihlanganisa i-galvanized, i-aluminium plated, ehlanganiswe neyiloni noma ipulasitiki, njll. Intambo yensimbi eyinsimbi ihlukaniswe yaba ucwecwe lokuqala oluncane kanye nocingo lwensimbi oluqinile ngemuva kokudweba uqweqwe oluwugqinsi, izici zomshini ze-coating eziwugqinsi ziphansi kunocingo olubushelelezi. intambo, kufanele isetshenziswe endaweni eyingozi kakhulu.
2. Ngezidingo zenqubo yocingo oluxhumekile
1. Intambo yensimbi ku-strand (Kuhlanganisa nocingo lwensimbi oluphakathi) kufanele ibe nobubanzi obufanayo, amandla afanayo kanye nezinga elifanayo le-zinc layer.
2. Ububanzi kanye nokubeka kwe-strand yensimbi kufanele kube iyunifomu futhi ingakhululeki ngemva kokusika.
3. Intambo yensimbi ku-strand kufanele iboshwe ngokuqinile, ingabi ne-interleaving, i-fracture futhi igobe.
Umucu wensimbi kufanele uqonde, uthambe, ube nengcindezi encane eyinsalela, futhi akufanele uvele ∽ ukuma ngemva kokunwetshwa.
I-5.1X3 isakhiwo sensimbi ye-strand wire kanye ne-overhead ground wire ayivunyelwe ukujoyina, ezinye izinhlobo ze-steel strand wire joints kufanele zishiselwe ekuhlanganyeleni, noma yimaphi amalunga amabili akufanele abe ngaphansi kwama-50m, ukujoyina kufanele kube ukwelashwa kwe-anticorrosion.
3. Ukunqamula ukungezwani komucu wensimbi
Kunezindlela ezimbili zokulinganisa ukungezwani kokuphuka kwentambo yensimbi
Indlela yoku-1: Ukulinganisa amandla aphukayo ayo yonke insimbi yensimbi.
Indlela yesi-2: Ukunquma ukungezwani okuphelele kokuphuka kwentambo yensimbi?
Ngokwefomula elandelayo:
Isamba sokuphulwa kwe-tension yocingo lwensimbi ku-strand = ukuqina okuncane okuphuka kwe-coefficient yokuguqulwa kwe-strand X
Isici sokuguqula?
Isakhiwo se-1X3 singu-1.08
Isakhiwo se-1X7 singu-1.08
Isakhiwo se-1X19 singu-1.11
Isakhiwo se-1X37 singu-1.17
4. Izinga eliphezulu
1. Ubuso bocingo lwensimbi ku-strand akufanele bunyatheliswe, luklwetshwe, luphuke, luhlakazeke futhi lugobe kanzima.
2. Ubuso be-strand kumele bungabi namafutha, ukungcola, amanzi nokunye ukungcola.
3. I-Strand split steel wire surface of the layer galvanized kufanele ibe iyunifomu futhi iqhubeke, akukho mkhuba wokuqhekeka nokuxebuka. Kodwa-ke, ubuso be-zinc layer buvunyelwe ukuba nenani elincane le-flash ne-white layer elincanyana kanye nomehluko wombala.
5. Ukumaka intambo yensimbi
Isibonelo sokumaka: isakhiwo esingu-1X7, ububanzi 6.0mm, amandla aqinile 1370M Pa, umucu wensimbi we-zinc wekilasi A omakwe :1X7-6.0-1370-A-YB/T 5004-2012
Ukupakisha, ukumaka kanye nesitifiketi sekhwalithi
Isitifiketi sokupakisha, ukumaka kanye nekhwalithi ye-strand yensimbi kufanele ihambisane ne-GB/T 2104.
Ngokuvamile, zonke izinhlobo ze-steel strand wire kufanele zilethwe ngethreyi. Ngokwesivumelwano sazo zombili izinhlangothi, kungangezwa iphepha elivikela umswakama, ilineni, indwangu elukiwe yepulasitiki nokunye okungeziwe okufakiwe.
