He inoa maʻamau ʻo Rebar no nā ʻaukā hao liʻiliʻi wela.ʻO ka papa o ka pahu kila wela maʻamau ka HRB a me ka helu haʻahaʻa loa o ka papa.ʻO H, R, a me B nā huaʻōlelo Pelekane mua o nā huaʻōlelo ʻekolu, Hotrolled, Ribbed, a me Bars.Hoʻokaʻawale ʻia nā pahu kila i ʻōwili ʻia i ʻekolu papa: HRB335 (ʻo 20MnS ka papa kahiko), HRB400 (ʻo 20MnSiV, 20MnSiNb, 20Mnti ka papa kahiko) a me HRB500.
Nānā nui
Paʻa kila wela i hoʻopili ʻia Ua hoʻohui ʻia ka leka mua o ka ʻōlelo Pelekania (Fine) o "fine" i ka inoa inoa o ka pahu kila wiliwili wela.like:
HRBF335HRBF400, HRBF500.ʻO nā māka kūpono no nā hale seismic me nā koi kiʻekiʻe: e hoʻohui iā E ma hope o nā māka e kū nei (e laʻa: HRB400E
HRBF400E)
Hoʻohana nui: hoʻohana nui ʻia i ka hana ʻenekinia kīwila e like me nā hale, nā alahaka, nā alanui, etc.
ʻO ka ʻokoʻa ma waena o ka rebar a me ka pā poepoe: ʻO ka ʻokoʻa ma waena o ka pahu a me ka ʻaoʻao poepoe aia nā iwi ʻaoʻao lōʻihi a me nā iwi ʻaoʻao ma luna o ka ʻili, ma ka maʻamau me ʻelua mau iwi ʻaoʻao lōʻihi a me nā iwi ʻaoʻao i puʻunaue like ʻia ma ka ʻaoʻao lōʻihi.ʻO ka Rebar kahi kila ʻāpana liʻiliʻi, hoʻohana nui ʻia no ka iwi o nā ʻāpana hale paʻa.I ka hoʻohana ʻana, pono ka ikaika mechanical, ka hana deformation a me ke kaʻina hana welding.ʻO nā billet maka no ka hana ʻana i nā rebars he kila structural carbon a i ʻole nā mea kila haʻahaʻa haʻahaʻa i mālama ʻia e ka sedation.
Hāʻawiʻia nā kila kila, nā pahu kila i hoʻopauʻia i ka'ōwili wela, maʻamau a iʻole ka wela wela.
ʻano ʻano
ʻElua mau ʻano hoʻohālikelike maʻamau no ka rebar;Hoʻokaʻawale ʻia kekahi e ke ʻano geometric, a hoʻokaʻawale ʻia a hoʻokaʻawale ʻia paha e like me ke ʻano kea o ka ʻaoʻao ʻaoʻao a me ke kaawale o nā iwi ʻaoʻao.
ʻAno, e like me ka British Standard (BS4449), ua māhele ʻia ka rebar i |type, type au.Hōʻike nui kēia hoʻohālikelike i ka hana hoʻopaʻa ʻana o ka rebar.ʻElua
ʻO ka hoʻohālikelike ʻana i ka hana (pae), e like me ke kūlana hoʻokō o koʻu ʻāina i kēia manawa, ʻo ka rebar (GB1499.2-2007) uea koʻokoʻo he 1499.1-2008), e like me ka māka ikaika.
ʻOkoʻa (kahi hua / ikaika tensile), hoʻokaʻawale ʻia ka rebar i 3 mau māka;i ka Japanese Industrial Standard (JISG3112), ua māhele ʻia ka rebar i nā ʻano 5 e like me ka hana piha;i ka British Standard (BS4461), ua kuhikuhi pū ʻia ka rebar He mau pae o ka hoʻāʻo hana.Eia kekahi, hiki ke hana ʻia ka rebar e like me ka noi.
Hoʻokaʻawale, e like me nā pahu kila maʻamau no ka paʻa paʻa a me nā pahu kila i hoʻomaʻamaʻa ʻia i ka wela no ka mea i hoʻopaʻa ʻia i hoʻopaʻa ʻia.
