IBonded PC Strand

I-1.Iintshayelelo: Ukususela kwi-2005 ukuveliswa kweentambo zokuqinisa ezizinzile / iipc strands kunye nokuphumla okuphantsi kuye kwaphuhliswa. Kwi-2016, ishishini lifake izixhobo ezitsha ezihlaziyiweyo ezivumela ukuvelisa imicu yokuqinisa ezinzile ukuya kwiitoni ezingama-300,000 ngonyaka.

Obona buchwepheshe buhlaziyiweyo buhlangabezana neemfuno zomthengi kwinkqubo ekhoyo ye

ulawulo lomgangatho zisetyenziswa kwimveliso imisonto '.

2.Izicelo: Imisonto yePC/Ukuqinisa imisonto ezinzileyo iveliswa ngoluhlu olubanzi lwezicelo xa kuveliswa izakhiwo ezinkulu: izakhiwo, izakhiwo, iibhulorho, iiconduit, amadama, izikhululo zeenqwelo moya, iitonela zokuxhoma, amaqonga okomba ioli, izikhululo zamandla enyukliya; kwimveliso yokulala koololiwe bekhonkrithi.

3.I-Advantageous:Imisonto yePC/Ukuqinisa imisonto ezinzileyo inomsebenzi ogqwesileyo wokuphumza okuphantsi kunye ne-ductility, enoluhlu olubanzi lwesicelo kulwakhiwo lwezibonelelo zorhwebo ezintsonkothileyo kunye nezoshishino.

I-1) Ukusetyenziswa kweentambo ezininzi zokuqinisa iintambo ezizinzileyo zivumela ukufezekisa amandla afanayo kwizakhiwo ezigxininisiweyo ngaphandle kokunyusa ububanzi kunye nenani leentambo ezinoqoqosho olucacileyo ngenxa yokuqina kwazo kwiihange.

2)Iimpawu ezintle zoomatshini bokuqiniswa kwemicu emva kobushushu kunye nonyango lomatshini ukuphuculwa okuqhubekayo kobuchwephesha kunokubaluleka okuqinisekileyo ekusebenziseni iimveliso zentsimbi kwishishini lokwakha kunye nokwenza imicu yokuqinisa ukwakhiwa kwekhonkrithi egxininisiweyo ngenye yeemveliso eziphambili.

I-4.Iimpawu: Ukusetyenziswa kweentambo zokuqinisa i-multi-strand endaweni yokuqiniswa kwe-rolling kuvumela ukufumana iimpawu zamandla aphezulu kunye nama-diameter amancinci kunye nobunzima besakhiwo sokuqinisa. Ukuguquguquka kweentambo kuququzelela kakhulu ukuyila kunye nokwakhiwa kwezakhiwo ezinzima.

5.Imigangatho : Imicu yePC/Imisonto eyomeleziweyo ezinzileyo yenziwa ngokuhambelana neemfuno zale migangatho ilandelayo:

I-1) Imicu ye-PC ngokwe-FprEN 10138-3: 2009 "I-Tensile reinforcement - iSigaba 3: I-Strand" - ngokwe-design 3- kunye ne-7-strands ukusuka kwi-wire of round or periodic cross-section;

2) Imitya yePC ngokwe-BS 5896: 2012 "Iingcingo zentsimbi ezinamandla okuqina okwethutyana kunye nemisonto ukusuka kuyo ukwenza uxinzelelo kwi-concrete Strands";

3) Imisonto yePC ngokweASTM A 416 / A416M-18 "Iinkcukacha eziqhelekileyo zemisonto yentsimbi yesi-7 ngaphandle kokugquma ikhonkrithi ecinezelekileyo". Ukusuka kwintambo yecandelo elijikelezileyo kuphela;

4) Iintambo zePC (iintambo zokuqinisa) ngokweGOST 13840-68 "Iintambo zokuqinisa intsimbi 1 × 7. Iimeko zobugcisa”;

I-5) Iintambo ze-PC (iintambo zokuqinisa) ngokweGOST R 53772-2010 "iintambo ezi-7 ezizinzileyo zokuqinisa iintambo zentsimbi. Iimeko zobugcisa.”;

I-6) I-PC yokuqinisa imisonto (iintambo) ngokwe-SFS - 1265 - 3: 2014"Iintsimbi zokucinezela izakhiwo ezicinezelekileyo-Icandelo 3: Strand"

6. IiPC Strands ngokovavanyo lwesizwe lobugcisa olusekelwe kwi-EN 10138, iinxalenye 1 kunye ne-3:

1) Umgaqo wobugcisa waseRomania ST 009-2011 "Iinkcazo zobuchwephesha kwiimveliso zetsimbi ezisetyenziselwa ukuqiniswa: iimfuno zokusebenza kunye neendlela" kunye nesivumelwano soBugcisa 001SC-01 / 275-2019 "Ukuqinisa i-strand yekhonkrithi egxininisiweyo"

2) Uvavanyo lobugcisa belizwe lasePoland ITB-KOT-2018/0637 inqaku le-1 "Iintambo ze-Steel prestressed ze-PJSC "STALKANAT-SILUR" ukusuka kwiingcingo ezigudileyo ";

3) UVavanyo lweSizwe lwezobuGcisa lwaseHungary NMÉ: A-16/2018 kunye ne-NMÉ: A-27/2019;

I-DIAMETER: ukusuka kwi-6,50 mm ukuya kwi-17,8 mm.

UKWAKHIWA: I-3-strands wire kunye ne-7-strands wire coating okanye ngaphandle kokugqoka.

I-RAW MATERIAL: I-wire-drawn-drawn, eyenziwe yintonga yocingo lwekhabhoni ephezulu yobubanzi obuyi-6,5 ~ 13,0 mm isetyenziselwa ukuveliswa kweentambo zokuqinisa.

Izixhobo ezitsha zemveliso yanamhlanje, i-laboratory yokuvavanya exhotyiswe ukuvavanywa kweempawu eziqhelekileyo kunye nezikhethekileyo, iingcali ezinamava ziqinisekisa ukwaneliseka kwazo naziphi na izicelo kunye nokulindela abathengi.

Ngesicelo somthengi, iintambo zingenziwa kwi-wire indented, ngelixa ucingo oluphakathi kwi-strand lwenziwe lula. Iintambo ezi-7/3 zingenziwa ngocingo olugudileyo kunye nocingo olungaphakathi.
