ʻO Rebar kahi inoa maʻamau no nā ʻaukā hao ʻili 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 mua o nā huaʻōlelo ʻekolu, Hotrolled, Ribbed, a me Bars.
Hoʻokaʻawale ʻia ka pahu kila liʻiliʻi wela i ʻekolu mau māka: HRB335 (ʻo 20MnSi ka papa kahiko), ʻekolu HRB400 (ʻo 20MnSiV ka papa kahiko, 20MnSiNb, 20Mnti), a me ka papa ʻehā HRB500.
ʻO ka Rebar kahi pahu kila liʻiliʻi ma luna o ka ʻili, ʻike ʻia hoʻi ʻo ka ribbed steel bar, maʻamau me 2 iwi ʻaoʻao longitudinal a me nā iwi ʻaoʻao i hoʻohele like ʻia ma ka ʻaoʻao lōʻihi.ʻO ke ʻano o ka ʻaoʻao ʻaoʻao he spiral, herringbone a me ka crescent shape.Hōʻike ʻia ma nā millimeters o ke anawaena inoa.ʻO ke anawaena inoa o ka lāʻau liʻiliʻi e pili ana i ke anawaena inoa o ka pahu poepoe o ka ʻāpana keʻa like.He 8-50 mm ke anawaena inoa o ka rebar, a he 8, 12, 16, 20, 25, 32, a me 40 mm na anawaena i oleloia.ʻO nā pahu kila i hoʻopaʻa ʻia i ke koʻikoʻi tensile ma ke kaʻa.Ma muli o ka hana a nā iwi ʻaoʻao, ua ʻoi aku ka ikaika o ka hoʻopaʻa ʻana o nā pahu kila me ka ʻiʻo, no laila hiki iā lākou ke pale aku i ka hana o nā ikaika o waho.Hoʻohana nui ʻia nā kaola kila liʻiliʻi i nā hale hale like ʻole, ʻoi aku ka nui, kaumaha, māmā a me nā hale kiʻekiʻe.
ʻenehana hana Rebar
Hana ʻia ka Rebar e nā wili liʻiliʻi.ʻO nā ʻano nui o nā wili liʻiliʻi: mau, semi-continuous a me ka lālani.ʻO ka hapa nui o nā wili liʻiliʻi hou a hoʻohana ʻia i ka honua holoʻokoʻa.ʻO nā wili wili kaulana ʻo ia nā wili wili kiʻekiʻe kiʻekiʻe a me 4-slice wili hana kiʻekiʻe.
ʻO ka billet i hoʻohana ʻia i ka wili liʻiliʻi liʻiliʻi e hoʻomau nei i ka hoʻolei ʻana i ka billet, ʻo ka lōʻihi o ka ʻaoʻao he 130 ~ 160mm, ʻo ka lōʻihi ma kahi o 6 ~ 12 mika, a ʻo ke kaumaha o ka billet hoʻokahi he 1.5 ~ 3 tons.Hoʻonohonoho ʻia ka hapa nui o nā laina ʻōwili ma ka ʻaoʻao a me ke kūpaʻa, no ka loaʻa ʻana o ka torsion-free rolling ma ka laina.E like me nā kikoʻī billet like ʻole a me ka nui o nā huahana i hoʻopau ʻia, aia he 18, 20, 22, a me 24 mau wili liʻiliʻi liʻiliʻi, a ʻo 18 ka mea nui.Hoʻohana ka ʻoloka bar i nā kaʻina hana hou e like me ka hele ʻana i ka umu wela, ka hoʻohaʻahaʻa wai kiʻekiʻe, ka ʻōwili haʻahaʻa haʻahaʻa, a me ka ʻōwili pau ʻole.Ke ulu nei ka ʻōwili a me ka ʻōwili waena ma ke ʻano o ka hoʻololi ʻana i nā bila nui a me ka hoʻomaikaʻi ʻana i ka pololei o ka ʻōwili ʻana.Hoʻonui i ka pololei a me ka wikiwiki (a hiki i 18m/s).ʻO nā kikoʻī o ka huahana he ф10-40mm, a aia pū kekahi ф6-32mm a i ʻole ф12-50mm.ʻO ke kila kila i hanaʻia he haʻahaʻa haʻahaʻa, medium a kiʻekiʻe ke kila kila a me ke kila kila haʻahaʻa i koi nuiʻia e ka mākeke;ʻo ka māmā holo kiʻekiʻe he 18m/s.ʻO kāna hana hana penei:
Imi hele wāwae → wili kaʻapuni → wili olokaʻa waena → wili hoʻopau → mea hoʻoluʻu wai → moena hoʻoluʻu → ʻakomi anu → mea helu ʻakomi → baler → wehe i ke kū.Ka helu helu paona: anawaena waho Х anawaena waho Х0.00617=kg/m.
