ʻElua mau ʻano hoʻokaʻawale maʻamau no ka rebar: ʻo ka hoʻokaʻawale ʻana ma ke ʻano geometric, a me ka hoʻokaʻawale ʻana a i ʻole ke ʻano e like me ke ʻano kea o ka iwi ʻaoʻao a me ke kaawale o nā iwiʻaoʻao. ʻAno II. Hōʻike nui kēia hoʻohālikelike i ka hana hoʻopaʻa ʻana o ka rebar. Hoʻokumu ʻia ka lua ma ka hoʻohālikelike hana (grade), e like me ke kūlana hoʻokō o koʻu ʻāina i kēia manawa, ʻo ka rebar (GB1499.2-2007) uea ʻo 1499.1-2008), e like me ke kiʻekiʻe o ka ikaika (kahi hua / tensile ikaika) ʻO ka rebar mahele i 3 papa; i ka Japanese Industrial Standard (JI SG3112), ua māhele ʻia ka rebar i nā ʻano 5 e like me ka hana piha; ma ka British Standard (BS4461), ua kuhikuhi pū ʻia kekahi mau māka o ka hōʻike hoʻokō rebar. Eia kekahi, hiki ke hoʻokaʻawale ʻia nā rebars e like me kā lākou hoʻohana ʻana, e like me nā pahu kila maʻamau no ka hoʻopaʻa ʻia ʻana a me nā pahu kila i hoʻomaʻamaʻa ʻia i ka wela no ka mea i hoʻopaʻa ʻia i hoʻopaʻa ʻia.
ʻO ka Rebar kahi pahu kila liʻiliʻi ma luna o ka ʻili, ʻike ʻia hoʻi ʻo ka pahu kila ribbed, 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 maikaʻi 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.
Hana ʻia ʻo Rebar e nā wili liʻiliʻi liʻiliʻi, a ʻo nā ʻano nui o nā wili liʻiliʻi: mau, semi-continuous a tandem. 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 mau 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 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. Wahi a 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 Bar rolling i nā kaʻina hana hou e like me ka hele ʻana i ka umu wela, ka hoʻohaʻahaʻa ʻana i ka wai kiʻekiʻe, ka ʻōwili haʻahaʻa haʻahaʻa, a me ka ʻōwili pau ʻole. Hoʻokumu ʻia ka ʻōwili a me ka ʻōwili waena no ka hoʻololi ʻana i nā billet nui a hoʻomaikaʻi i ka pololei o ka ʻōwili ʻana. ʻO ka nui o ka hoʻopau ʻana i nā wili ʻoi aku 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 nā papa kila i hanaʻia he haʻahaʻa haʻahaʻa, medium a kiʻekiʻe ke kila kila a me ke kila kila haʻahaʻa i makemake nuiʻia ma ka mākeke; ʻO ka māmā holo kiʻekiʻe he 18m/s. ʻO kāna hana hana penei:
ʻO ka umu hele wāwae → wili liʻiliʻi → wili liʻiliʻi waena → wili hoʻopau → mea hoʻoluʻu wai → moe hoʻomaha → ʻāhi anuanu → mea helu ʻakomi → mīkini bale → hāʻawi ʻia ka papa hoʻoiho e Shanghai Jiuzheng Environmental Protection Building Materials Co., Ltd. e hāʻawi i ke kaumaha theoretical Ka helu ana o ka rebar Formula: Outer DiameterХOuter DiameterХ0.00617=kg/m Nā kiko'ī Weight Manufacturer 6.50.260 Jiuzheng Iron and Steel 8.00.395 Jiuzheng Iron and Steel 100.617 Jiuzheng Iron and Steel 120.888 Iron and Steel 120.888 Iron and Steel Jiuzheng Iron a me Ke kila 182.00 Jiuzheng hao a me ka hao 202.47 Jiuzheng hao 222.98 Jiuzheng hao a me kila 253.85 Jiuzheng hao a me kila 284.83 Jiuzheng hao 326.31 Jiuzheng hao a me kila.
