Ua like ke ʻano o ka ʻāpana me ka ʻaoʻao ʻāpana waiwai o ka huaʻōlelo Latin nui H, i ʻike ʻia hoʻi ʻo ke kaola kila honua, ka ʻaoʻao ākea I-beam a i ʻole ka flange I-beam like.ʻO ka ʻāpana keʻa o ka H-beam ka mea maʻamau i ʻelua mau ʻāpana, ka pā pūnaewele a me ka pā flange, ʻike ʻia hoʻi ʻo ka pūhaka a me ka ʻaoʻao.
hoʻohana
Hoʻohana nui ʻia nā H-beams a hoʻohana nui ʻia no:
nā hale kīwila a me nā hale hana ʻenehana;nā mea kanu ʻoihana nui ākea a me nā hale kiʻekiʻe o kēia wā, ʻoi aku ka nui o nā mea kanu ʻoihana ma nā wahi me ka hana seismic pinepine a me nā kūlana hana wela kiʻekiʻe;e koi ana i ka hiki ke lawe nui a me ka ʻāpana ʻāpana ʻO nā alahaka nui me ka paʻa maikaʻi a me ka lōʻihi;mea kaumaha;nā alaloa;iwi iwi moku;koʻu kākoʻo;ka mālama ʻana i ke kahua a me ka ʻenekinia embankment;nā ʻāpana mīkini like ʻole.

Nui nā kikoʻī huahana o ka H-beam, a penei nā ʻano hoʻohālikelike.(1) E like me ka laula flange o ka huahana, ua maheleia i laula flange, waena flange a haiki flange H-beam.ʻOi aku ka nui a i ʻole like me ke kiʻekiʻe o ka pūnaewele H. ʻO ka laulā o ka flange B o ka flange H-beam ʻoi aku ka nui o ke kila o ka ʻaoʻao waena. 2) E like me ka hoʻohana ʻana i ka huahana, ua māhele ʻia i ka lāʻau kila H-ʻano, kolamu kila H-ʻano, puʻu kila H-ʻano, a me ka lāʻau kila flange H-like.I kekahi manawa, ua hoʻokomo pū ʻia nā awāwa wāwae ʻālike a me nā kuʻekuʻe T flange like i loko o ka laulā o nā kaola H.ʻO ka maʻamau, hoʻohana ʻia ka flange H-beam haiki e like me ka mea kukuna, a hoʻohana ʻia ka flange H-beam ākea ma ke ʻano he kolamu.(3) E like me ke ʻano hana, ua māhele ʻia i ka welded H-beam a me ka H-beam i ʻōwili ʻia.(4) E like me ka nui, ua mahele ia i ka nui, waena a me ka liʻiliʻi H-beams.ʻO ka mea maʻamau, kapa ʻia nā huahana me kahi kiʻekiʻe pūnaewele H ma luna o 700mm, ʻo nā mea me ke kiʻekiʻe o 300 a 700mm i kapa ʻia ʻo medium, a ʻo nā mea me ke kiʻekiʻe ma lalo o 300mm ua kapa ʻia he liʻiliʻi.Ma ka hopena o 1990, ʻo ka H-beam nui loa o ka honua he 1200mm ke kiʻekiʻe a me ka laula flange o 530mm. ʻO ka H-beam kahi ʻāpana waiwai a me ka kiʻekiʻe-efficiency profile me ka ʻoi aku ka maikaʻi o ka māhele ʻāpana cross-sectional a ʻoi aku ka ikaika kūpono- lākiō-kaumaha.Ua kapa ʻia ʻo ia no ka mea ua like kona ʻāpana keʻa me ka leka Pelekane "H".No ka mea ua hoʻonohonoho ʻia nā ʻāpana a pau o ka H-beam ma nā kihi ʻākau, ua loaʻa i ka H-beam nā pōmaikaʻi o ke kūpaʻa kūlou ikaika, ka hana maʻalahi, ka mālama ʻana i ke kumukūʻai a me ke kaumaha māmā ma nā ʻaoʻao āpau, a ua hoʻohana nui ʻia.
