Imigangatho/Iikhrayitheriya zokuqinisa imisonto ezinzileyo (iintambo)/iintambo zepc yi-Univac

Iintambo ezizinzisiweyo zokuqinisa (iintambo) zinoluhlu olubanzi lwesicelo ekwakhiweni kwezixhobo eziyinkimbinkimbi kunye nezoshishino.

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 kwezakhiwo ezinzima.

Ukuveliswa kweentambo zokuQinisekisa ezinzisiweyo (iintambo) kunye nokuphumla okuphantsi kuqalwe ngo-2004. Izixhobo ezitsha zanamhlanje zokwenziwa kweemveliso ezihlangabezana nazo zonke iimfuno zangoku zifakwe kwi-2012-2019.

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

Imisonto eyomeleziweyo ezinzileyo yenziwa ngokuhambelana neemfuno zale migangatho ilandelayo:

1. imicu ngokwe-FprEN 10138-3: 2009 "I-Tensile reinforcement - Icandelo lesi-3: i-Strand" - ngokwe-design 3- kunye ne-7-strands ukusuka kwi-wire of round or periodic cross-section;

2.intambo ngokwe-BS 5896: 2012 “Iingcingo zentsimbi ezinamandla okuqina okwethutyana kunye nemisonto ukusuka kuyo ukwenza i-prestress kwikhonkrithi. Imisonto”;

I-3.i-strands ngokwe-ASTM A 416 / A416M-18 "Iinkcazo eziqhelekileyo kwiintambo zetsimbi ezi-7 ngaphandle kokugubungela ikhonkrithi egxininisiweyo". Ukusuka kwintambo yecandelo elijikelezileyo kuphela;

4.4. imicu (ukuqinisa iintambo) ngokweGOST 13840-68 "Iintambo zokuqinisa intsimbi 1 × 7. Iimeko zobugcisa”;

I-5.strands (ukuqinisa iintambo) ngokweGOST R 53772-2010 "i-7-wire stabilized ukuqinisa iintambo zetsimbi. Iimeko zobugcisa.”;

6.ukuqinisa imisonto ezinzileyo (iintambo) ngokwe-SFS – 1265 – 3:2014“Iintsimbi zokucinezela izakhiwo ezicinezelekileyo-Icandelo 3: Strand”

Imisonto ngokovavanyo lwesizwe lobugcisa olusekwe kwi-EN 10138, icandelo 1 kunye ne-3:

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

2.I-Hungarian National Technical Assessment NMÉ: A-16/2018 kunye ne-NMÉ: A-27/2019;

3. Umgaqo wobugcisa waseRomania i-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"

ISICELO:yokomelezwa kolwakhiwo lwekhonkrithi enoxinzelelo lwangaphambili.

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

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

I-MATRIAL: I-wire-drawn-drawn, eyenziwe yintonga ye-carbon wire ye-diameter ye-6,5 ~ 13 mm isetyenziselwa ukuveliswa kweentambo zokuqinisa.

UKWENZIWA KWEKHEMIKHALI LWENKANTSI:

Ngesicelo somthengi, iintambo zingenziwa kwi-wire indented, ngelixa ucingo oluphakathi kwi-strand lwenziwe lula.
