Bonded PC Strand
Tlhaloso ea Sehlahisoa
1.Introductions: Ho tloha 2005 tlhahiso ea likhoele tse tiisitsoeng tsa ho matlafatsa / pc tse nang le phomolo e tlase e ntlafalitsoe. Ka 2016, k'hamphani e ile ea kenya ts'ebetsong lisebelisoa tse ncha tsa morao-rao tse lumellang ho hlahisa likhoele tsa matlafatso tse tsitsitseng ho fihlela ho lithane tse 300,000 ka selemo.
Theknoloji ea morao-rao ka ho fetisisa e finyellang litlhoko tsa moreki tsamaisong e teng ea
taolo ea boleng li sebelisoa tlhahiso ea likhoele.
2. Litšebeliso: likhoele tsa PC / Matlafatso e tsitsitseng li hlahisoa ka mefuta e mengata ea ts'ebeliso ha ho etsoa meaho e meholo: meaho, meaho, marokho, likotopo, matamo, maemelo a lifofane, lithanele li-hangars, sethala sa ho cheka oli, liteishene tsa matla a nyutlelie; tlhahisong ea batho ba robalang seporo sa konkreite.
3.Advantageous: PC strands / Reinforcement strands stabilised na le tshebetso e babatsehang ea high low boikhathollo le ductility, tse nang le mefuta e fapaneng ya tshebediso kahong ea e rarahaneng le e ikarabellang khoebo le mehaho ea indasteri.
1) Ts'ebeliso ea likhoele tse tsitsitseng tse matlafatsoang ka lithapo tse ngata li lumella ho fihlela matla a ts'oanang ho meaho e hahelletsoeng ntle le ho eketsa bophara le palo ea likhoele tse nang le moruo o hlakileng ka lebaka la ho tiisa ha tsona liankora.
2) Litšobotsi tse ntle tsa mochini oa likhoele tse matlafatsang kamora mocheso le kalafo e tsoelang pele ea theknoloji li na le bohlokoa bo tiileng ba ts'ebeliso ea lihlahisoa tsa tšepe indastering ea meaho le ho etsa likhoele tsa matlafatso bakeng sa meaho ea konkreite e hatelletsoeng pele ke e 'ngoe ea lihlahisoa tsa mantlha.
4. Litšobotsi: Tšebeliso ea likhoele tse matlafatsang tse nang le mefuta e mengata ho e-na le ho matlafatsa ho roala ho lumella ho fumana litšobotsi tse matla tse nang le li-diameter tse nyenyane le boima ba mohaho o matlafatsang. Ho feto-fetoha ha likhoele ho thusa haholo ho qaptjoa le ho haha mehaho e rarahaneng.
5.Standards : Likhoele tsa PC / likhoele tse matlafalitsoeng li entsoe ho latela litlhoko tsa litekanyetso tse latelang:
1) likhoele tsa PC ho latela FprEN 10138-3: 2009 "Tensile reinforcement - Karolo ea 3: Strand" - ho latela moralo oa 3- le 7-likhoele ho tloha terata ea ho pota-pota kapa nako le nako;
2) likhoele tsa PC ho latela BS 5896: 2012 "terata ea tšepe e nang le matla a phahameng a nakoana le likhoele tse tsoang ho eona ho theha khatello ka likhoele tsa konkreite";
3) likhoele tsa PC ho latela ASTM A 416 / A416M-18 "Litlhaloso tse tloaelehileng bakeng sa likhoele tsa tšepe tse 7-wire ntle le konkreite e hatelletsoeng pele". Ho tloha terata ea karolo e chitja feela;
4) likhoele tsa PC (lithapo tse matlafatsang) ho latela GOST 13840-68 "Liropo tse matlafatsang tsa tšepe 1 × 7. Maemo a tekheniki”;
5) likhoele tsa PC (lithapo tse matlafatsang) ho latela GOST R 53772-2010 "7-terata e tsitsitse lithapo tsa tšepe tse matlafatsang. Maemo a tekheniki.”;
6) likhoele tse matlafatsang tsa PC (liropo) ho latela SFS - 1265 - 3: 2014 "Mehaho e hatellang ea litšepe - Karolo ea 3: Strand"
6. PC Strands ho latela litlhahlobo tsa tekheniki tsa naha tse thehiloeng ho EN 10138, likarolo tsa 1 le 3:
1) Taolo ea tekheniki ea Romania ST 009-2011 "Litlhaloso tsa theknoloji bakeng sa lihlahisoa tsa tšepe tse sebelisoang e le matlafatso: litlhoko tsa ts'ebetso le litekanyetso" le tumellano ea tekheniki 001SC-01 / 275-2019 "Ho matlafatsa khoele bakeng sa konkreite e hatelitsoeng"
2) Tlhahlobo ea tekheniki ea naha ea Poland ITB-KOT-2018/0637 khatiso ea 1 "Likhoele tse hatisitsoeng ka tšepe tsa PJSC "STALKANAT-SILUR" ho tloha lithapong tse boreleli ";
3) Hungary National Technical Assessment NMÉ: A-16/2018 le NMÉ: A-27/2019;
DIAMETER: ho tloha ho 6,50 mm ho ea ho 17,8 mm.
SEBOPEHO: terata ea likhoele tse 3 le khoele ea likhoele tse 7 kapa ntle le ho roala.
TLHOKOMELISO E HLAHANG: terata e huloang ke serame, e entsoeng ka molamu oa terata e phahameng ea carbon ea bophara ba 6,5 ~ 13,0 mm e sebelisoa bakeng sa tlhahiso ea likhoele tse matlafatsang.
