Iterambere rya PC Strands hamwe nicyuma gikoreshwa mubyuma bya sisitemu

Ibicuruzwa byibyuma byateye imbere byateye imbere cyane kuva 1950 byikinyejana gishize, hari ingingo ebyiri zingenzi mubyerekezo byiterambere. Ubwa mbere, imbaraga zibikoresho zigenda ziyongera buhoro buhoro, kuburyo byagabanije ingano nuburemere bwibigize ibyubahiro, ndetse bikagabanya igiciro cyumushinga; Icya kabiri, dushingiye ku kuzamura imbaraga, dukwiye kwitondera iterambere ryibikoresho bifite imikorere myinshi yo kurwanya ruswa, kugirango tunonosore igihe kirekire cyibikoresho byicyuma kandi bizigama amafaranga yo kubungabunga.

Kubyerekeranye nimbaraga zikomeye kandi zoroheje-yoroheje ibyuma, inzira yiterambere ryabo igabanijwemo ibice bine: imigozi isanzwe yoroshye kandi yoroheje - imigozi yicyuma gisanzwe hamwe nicyuma kidahambiriwe - ibyuma bitagira umuringa - ibyuma bya epoxy. Mu byiciro bitatu byambere byiterambere, clips ikora ya ankeri ihujwe numugozi wibyuma birasa; Igishushanyo cyacyo, gutunganya no gutanga umusaruro byabaye binini. Icyiciro cya kane cyiterambere, ni ukuvuga epoxy ibyuma byicyuma, kuri ubu hari ubwoko butatu bwibyuma bya epoxy ibyuma kumasoko mpuzamahanga ndetse nimbere mu gihugu. Imwe murimwe ni insinga imwe yoroheje-epoxy yumurongo wibyuma, ni ukuvuga insinga ndwi zicyuma mumurongo wibyuma zometseho epoxy itandukanijwe ukwayo, kandi uburebure bwa coating ni buke (hafi 0.1 ~ 0.2mm); Iya kabiri ni epoxy itwikiriwe nicyuma, ni ukuvuga, igice cyinyuma cyumugozi wicyuma cyashizweho na epoxy coating, kandi nta rezo ya epoxy yuzuza icyuho kiri hagati yimigozi yicyuma, kandi ubunini bwububiko bwa epoxy yo hanze ni (hafi 0,65 ~ 1.15mm); Iya gatatu ni epoxy yuzuyemo icyuma cyuzuzanya, cyuzuyemo epoxy resin kumurongo winyuma no mu cyuho, kandi nicyuma cyonyine cya epoxy cyuma cyujuje ubuziranenge bwa ASTM A882 / A882M-04a na ISO14655: 1999.

Sisitemu yicyubahiro ya sisitemu igenda itera imbere buhoro buhoro hamwe niterambere ryibyuma bizwi, byombi ntibishobora gutandukana. Hamwe no gukura buhoro buhoro kwuzuza epoxy yuzuye ibyuma bya tekinoroji, sisitemu yayo nayo yagiye itera imbere buhoro buhoro. Byombi bifatanya, kandi byashyizwe mubikorwa byinshi byo kubaka ikiraro cyumuhanda nkikiraro guma guma guma guma, ikiraro guma guma guma guma guma, icyubahiro cyo hanze, inkoni zihuza ikiraro hamwe n amabuye atangaje.

Univac New Material Tech.Manufacturing Co., Ltd. ni uruganda rukora umwuga wo gukwirakwiza no gukwirakwiza imbaraga zikomeye kandi zoroheje-zoroheje-zoroheje zicyuma cyamamare, insinga zicyuma, ibyuma-bishyushye-byuma, ibyuma bitagira umupaka, imigozi ya epoxy-yubatswe na epoxy sisitemu zabo zunganira ibyuma, ubwiza bwibicuruzwa byicyuma byujuje ubuziranenge byujuje ubuziranenge mpuzamahanga BS 5896: 2012, FprEN 10138: 2009, ASTM A416 / 416M: 2012, ISO 14655: 1999 "Epoxy Coated Steel Grain Wire for beto Prestressed" nibisabwa ya Amerika isanzwe ASTM A882 / A882M-04a "Ibisobanuro birambuye kuri Epoxy Yuzuye Yuzuyemo Imiyoboro Irindwi Yashizweho Icyuma"; Sisitemu ya ankoring yateje imbere sisitemu ya kabili yagumyeho, sisitemu yagumye kumurongo kubiraro bimwe na bimwe bigumaho, sisitemu yo kwubahiriza hanze, sisitemu yo guhuza ikiraro cya archive hamwe na sisitemu ya geotechnique, yakoreshejwe mumishinga myinshi.
