I-Bonded PC Strand

1.Izingeniso: Kusukela ngo-2005 ukukhiqizwa kwezintambo zokuqinisa ezizinzile/ama-pc strands anokuphumula okuphansi kuye kwathuthukiswa. Ngo-2016, inkampani yaqala ukusebenza imishini emisha yakamuva evumela ukukhiqiza izintambo zokuqinisa ezizinzile ezifika kumathani angu-300,000 ngonyaka.

Ubuchwepheshe obukamuva kakhulu obuhlangabezana nezidingo zomthengi ohlelweni olukhona lwe

ukulawulwa kwekhwalithi kusetshenziswa ekukhiqizeni imicu.

2.Izicelo: Izintambo ze-PC/Ukuqinisa okuqinisiwe kwezintambo zikhiqizwa ngezindlela eziningi ezahlukene lapho kukhiqizwa izakhiwo ezinkulu: izakhiwo, izakhiwo, amabhuloho, amapayipi amanzi, amadamu, izikhumulo zezindiza, ama-hangars emihubhe, izinkundla zokumba uwoyela, iziteshi zamandla enuzi; ekukhiqizeni izindawo zokulala zikaloliwe zikakhonkolo.

3.Okuzuzisayo:Imicu ye-PC/Ukuqinisa okuqinisiwe kwezintambo kunokusebenza okuhle kakhulu kokunethezeka okuphansi okuphansi kanye ne-ductility, enezinhlobonhlobo zezinhlelo zokusebenza ekwakhiweni kwezindawo zohwebo eziyinkimbinkimbi nezinomthwalo wemfanelo nezimboni.

1) Ukusetshenziswa kwezintambo eziqinisiwe zokuqinisa izintambo eziningi kuvumela ukuzuza amandla afanayo ekwakhiweni okugcizelelwe ngaphandle kokwandisa ububanzi kanye nenani lezintambo ezinomnotho osobala ngenxa yokuqiniswa kwazo kumahange.

2)Izici ezinhle zemishini yezintambo zokuqinisa ngemva kokushisa nokwelashwa kwemishini okuqhubekayo ukuthuthukiswa kobuchwepheshe kunokubaluleka okubalulekile ekusetshenzisweni kwemikhiqizo yensimbi embonini yezokwakha kanye nokwenza izintambo zokuqinisa ukwakhiwa kukakhonkolo ocindezelwe ngomunye wemikhiqizo eyinhloko.

I-4.Izici: Ukusetshenziswa kwezintambo zokuqinisa izintambo eziningi esikhundleni sokuqinisa ukugoqa kuvumela ukuthola izici zamandla aphezulu ngamadayimitha amancane nesisindo sesakhiwo sokuqinisa. Ukuguquguquka kwezintambo kusiza kakhulu ukuklama nokwakhiwa kwezakhiwo eziyinkimbinkimbi.

5.Amazinga : Izintambo ze-PC/Imicu eqinisiwe eqinisiwe yenziwa ngokuhambisana nezidingo zala mazinga alandelayo:

1) Imicu ye-PC ngokuya nge-FprEN 10138-3: 2009 “Ukuqinisa i-Tensile – Ingxenye 3: I-Strand” - ngokuya ngomklamo ongu-3- kanye nemicu engu-7 ukusuka kucingo oluyindilinga noma lwesiqephu sezikhathi ezithile;

2）Izintambo ze-PC ngokuya nge-BS 5896: 2012 “Intambo yensimbi enamandla amakhulu esikhashana eqinile nemicu esuka kuyo ukuze yenze i-prestress kuma-Strands kakhonkolo”;

3）Imicu ye-PC ngokuya nge-ASTM A 416 / A416M-18 “Izincazelo ezijwayelekile zemicu yensimbi enezintambo ezi-7 ngaphandle kokumbozwa kukakhonkolo ocindezelwe ngaphambili”. Kusuka ocingweni lwesigaba esiyindilinga kuphela;

I-4) Izintambo ze-PC (izintambo zokuqinisa) ngokusho kwe-GOST 13840-68 "Izintambo zokuqinisa insimbi 1 × 7. Izimo zobuchwepheshe”;

5) Izintambo ze-PC (izintambo eziqinisayo) ngokuya nge-GOST R 53772-2010 “izintambo zensimbi eziqinisiwe ezingu-7. Izimo zobuchwepheshe.”;

6) Izintambo eziqinisiwe ze-PC (izintambo) ngokuya nge-SFS – 1265 – 3:2014“Izakhiwo ezicindezelwayo zensimbi ezicindezelweyo – Ingxenye 3: I-Strand”

6. Ama-PC Strands ngokokuhlola kobuchwepheshe kukazwelonke okusekelwe ku-EN 10138, izingxenye 1 kanye no-3:

1) Umthethonqubo wezobuchwepheshe waseRomania ST 009-2011 "Ukucaciswa kobuchwepheshe bemikhiqizo yensimbi esetshenziswa njengokuqinisa: izidingo zokusebenza nemibandela" kanye nesivumelwano sobuchwepheshe 001SC-01 / 275-2019 "Ukuqinisa umucu wokhonkolo ocindezelwe"

2) Ukuhlolwa kobuchwepheshe kuzwelonke kwasePoland ITB-KOT-2018/0637 uhlelo 1 “Imicu yensimbi egcizelelwe ngaphambili ye-PJSC “STALKANAT-SILUR” evela ezintanjeni ezibushelelezi ”;

3) I-Hungarian National Technical Assessment NMÉ: A-16/2018 kanye ne-NMÉ: A-27/2019;

I-DIAMETER: kusuka ku-6,50 mm kuya ku-17,8 mm.

UKWAKHIWA: Izintambo ezi-3-micu kanye ne-7-strings wire coating noma ngaphandle kokunamathela.

I-RAW MATERIAL: Intambo edonswa ngokubanda, eyenziwe ngenduku ye-carbon wire ephezulu yobubanzi obuyi-6,5 ~ 13,0 mm isetshenziselwa ukukhiqizwa kwezintambo zokuqinisa.

Imishini emisha yesimanje yokukhiqiza, ilabhorethri yokuhlola ehlomele ukuhlolwa kwezakhiwo ezijwayelekile nezikhethekile, ochwepheshe abanolwazi baqinisekisa ukwaneliseka kwanoma yiziphi izicelo nokulindelwe ngamakhasimende.

Ngesicelo sekhasimende, izintambo zingenziwa ngocingo olugobile, kuyilapho ucingo oluphakathi ku-strand lwenziwa bushelelezi. Izintambo ezingu-7/3-zezintambo zingenziwa ngocingo olubushelelezi nangocingo oluyizinsika.
