Rebar HRB355 HRB400 HRB400 HRB500 8mm 10mm 14mm 14mm 14mm 14mm 16mm 14mm 16 hli Ribbed Bar Defromed Barr

1) Nominal lub cheeb ntau thiab pom zoo txoj kab uas hla
The nominal diameter of steel bars ranges from 6 to 50mm, and the standard recommended nominal diameters of steel bars are 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, and 50mm.
2) Kev pub rau kev sib txawv ntawm cov duab nto thiab qhov loj ntawm cov pob ribbed steel bar
Tus tsim qauv ntawm Ribbed Steel cov tuav yuav tsum ua kom tau raws li cov kev cai hauv qab no:
Lub kaum ntse ntse β ntawm transverse tav thiab tus hlau bar axis yuav tsum tsis pub tsawg tshaj 45 degrees. Thaum lub kaum sab xis tsis muaj ntau dua 70 degrees, cov kev taw qhia ntawm cov kab tshuam transverse ntawm ob sab ntawm tus hlau bar yuav tsum rov qab los;
Lub nominal twb mus l ntawm cov kab tshuam transverse yuav tsum tsis txhob loj dua 0.7 zaug ntawm nominal txoj kab ntawm cov tuav;
Lub kaum sab xis α ntawm ib sab ntawm cov tav toj thiab saum npoo ntawm lub bar steel yuav tsis tsawg tshaj 45 degrees;
Qhov suav ntawm cov khoob (nrog rau qhov dav ntawm longitudinal ribs) ntawm qhov kawg ntawm transverse uas nyob ib sab ntawm cov kab hlau yuav tsum tsis txhob loj dua 20% ntawm ib puag ncig ntawm cov hlau bar;
Thaum lub nominal lub cheeb ntawm cov hlau bar tsis ntau dua 12 hli, cov txheeb ze cov cheeb tsam yuav tsum tsis pub tsawg tshaj 0.055; Thaum lub nominal lub cheeb yog 14mm thiab 16 hli, qhov chaw txheeb ze yuav tsum tsis tsawg tshaj 0.060; Thaum lub nominal diaminal loj tshaj 16mm, tus txheeb ze tav cheeb tsam yuav tsum tsis pub tsawg tshaj 0.065. Saib Daim Ntawv Ntxiv C rau kev xam ntawm thaj tsam tus txheeb ze.
Ribbed steel tuav feem ntau muaj longitudinal bars, thiab tseem muaj cov uas tsis muaj cov kab ntev;
