Rebar Hrb355 Hrb400 Hrb500 8mm 10mm 12mm 14mm 16mm Ribbed bar

1) Nominal dhayamita siyana uye yakakurudzirwa dhayamita
Iyo dhayamita yematanho esimbi inotangira pa6 kusvika pa50mm, uye chiyero chinokurudzirwa mazita emadhayamita emasimbi 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, uye 50mm.
2) Kutsauka kunobvumirwa kwechimiro chepamusoro uye saizi yembabvu simbi bar
Iyo misimboti yekugadzira ye ribbed simbi mabara anofanirwa kuita zvinotevera zvinodiwa:
Iyo kona β pakati pembabvu inochinjika uye simbi bar axis haifanirwe kunge iri pasi pe45 madhigirii. Kana iyo kona inosanganisirwa isiri yakakura kupfuura 70 madhigirii, kutungamira kwemazariro akachinjika pamativi ese esimbi simbi inofanira kupesana;
Iyo yezita spacing l yemabhawa anochinjika haifanire kunge yakakura kudarika 0.7 times the nominal diameter of the bars;
Iko kona α pakati pedivi rembabvu yakachinjika uye pamusoro pesimbi yesimbi haifaniri kunge iri pasi pe45 degrees;
Huwandu hwemagapu (kusanganisira hupamhi hwembabvu refu) pamigumo yembabvu dzakachinjika pamativi ese ari padyo nesimbi yesimbi haifanire kunge yakakura kupfuura 20% yezita rekutenderera kwesimbi bar;
Kana iyo dhayamita yezita resimbi yesimbi isingasviki 12mm, nzvimbo yembabvu yehama haifanire kunge iri pasi pe0.055; apo dhayamita yezita iri 14mm uye 16mm, nzvimbo yembabvu haifanirwe kunge iri pasi pe0.060; kana iyo dhayamita yezita yakakura kupfuura 16mm, nzvimbo yembabvu yehama haifanire kunge iri pasi pe0.065. Ona Appendikisi C yekuverenga nzvimbo yembabvu.
Mbabvu simbi mbariro kazhinji ane longitudinal mbariro, uye kune zvakare ayo asina longitudinal mbariro;
