ʻO ka I-beam he lālā i kūkulu ʻia me kahi ʻāpana keʻa I-like (e like me ke kapikala "I" me nā serifs) a i ʻole ke ʻano H. ʻO nā huaʻōlelo ʻenehana ʻē aʻe e pili ana i ka H-beam, I-section, universal column (UC), W-beam (kū no "wide flange"), universal beam (UB), rolled steel joist (RSJ), a pālua-T. Hanaʻia lākou i ke kila a hiki ke hoʻohanaʻia i nāʻano hana hana.
Ma lalo nei, e hoʻohālikelike kākou i nā ʻokoʻa ma waena o ka H-beam a me I-beam mai kahi hiʻohiʻona ʻokoʻa. Nā noi o ka H-beam
Hoʻohana maʻamau ʻia ka H-beam i nā papahana e koi ana i nā lōʻihi lōʻihi a me nā haʻahaʻa haʻahaʻa kiʻekiʻe, e like me nā alahaka a me nā hale kiʻekiʻe.
H Beam Vs I Beam
ʻO ke kila ka mea hiki ke hoʻololi, hoʻohana mau ʻia. ʻO H Beam lāua ʻo I Beam nā mea hana maʻamau i hoʻohana ʻia i ke kūkulu hale ʻoihana.
Ua like nā ʻano ʻelua no ka poʻe maʻamau, akā aia nā ʻokoʻa nui ma waena o kēia mau mea ʻelua, he mea nui e ʻike.
Ua kapa ʻia ka ʻaoʻao ākea o nā kukuna H a me I he flanges, ʻoiai ʻo ka ʻaoʻao kū i kapa ʻia ʻo ka "pūnaewele." Kōkua ka pūnaewele i ka hoʻopaʻa ʻana i nā ikaika shear, ʻoiai ua hoʻolālā ʻia nā flanges e kū i ka manawa piʻo.
He aha wau, e Beam?
He ʻāpana hoʻolālā ia e like me ke kapikala I. Aia ʻelua flanges i hoʻopili ʻia e ka pūnaewele. He slop ka ʻili o loko o nā ʻaoʻao ʻelua, maʻamau, 1:6, ʻo ia ka mea e mānoanoa ai i loko a lahilahi i waho.
ʻO ka hopena, hana maikaʻi ia i ke kau ʻana ma lalo o ke kaomi pololei. He mau ʻaoʻao liʻiliʻi kēia kukuna a ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe o ke keʻa ma mua o ka laula o ka flange.
Ma muli o ka hoʻohana ʻana, loaʻa nā ʻāpana I-beam ma kahi ākea o ka hohonu, ka mānoanoa pūnaewele, ka laulā flange, ke kaupaona, a me nā ʻāpana.
He aha ka H Beam?
He lālā hoʻolālā hoʻi ia e like me ke kapikala H i loko o ke kila ʻōwili. Hoʻohana nui ʻia nā kaola H-ʻāpana no nā hale kūʻai a me nā hale noho ma muli o ko lākou ikaika-a-kaumaha ratio a me nā waiwai mechanical kiʻekiʻe.
ʻAʻole like me ka I beam, ʻaʻohe o loko o nā flanges H beam, e maʻalahi ke kaʻina hana kuʻi. Ua like ka mānoanoa o nā flanges ʻelua a ua kūlike kekahi me kekahi.
ʻOi aku ka maikaʻi o kāna mau ʻano ʻāpana keʻa ma mua o ka I beam, a ʻoi aku ka maikaʻi o nā waiwai mechanical no kēlā me kēia paona e mālama ai i ka waiwai a me ke kumukūʻai.
ʻO ia ka mea i makemake nui ʻia no nā paepae, mezzanines, a me nā alahaka.
I ka nānā mua ʻana, ua like ke ʻano o nā kaola hao ʻāpana H a me ka ʻāpana I, akā pono e ʻike kekahi mau ʻokoʻa koʻikoʻi ma waena o kēia mau kaola kila ʻelua.
Kinohi
Ua like ke kukuna h me ke kinona o ka Capital H, a o ka I beam ke kinona o Capital I.
Hana ʻana
Hana ʻia nā I-beam ma ke ʻano he ʻāpana hoʻokahi, ʻoiai ʻo H-beam he ʻekolu mau papa metala i wili pū ʻia.
Hiki ke hana ʻia nā kaola H i kēlā me kēia nui i makemake ʻia, ʻoiai ka hiki i ka mīkini wili ke kaupalena i ka hana ʻana o nā I-beams.
ʻO nā lehelehe
Ua like ka mānoanoa o nā ʻaoʻao o ka lālani H a ua like pū kekahi me kekahi, ʻoiai ua hoʻopaʻa aku au i nā flanges me ka manaʻo o 1: a hiki i 1:10 no ka ʻoi aku o ka hiki ke amo.
Mānoanoa Pūnaewele
He pūnaewele ʻoi aku ka mānoanoa o ka h beam e like me ka I beam.
Ka helu o nā ʻāpana
Ua like ke kukuna h-section me kahi ʻāpana metala hoʻokahi, akā he bevel kahi i hui pū ʻia ai ʻekolu papa metala.
ʻOiai ʻaʻole i hana ʻia ka lāʻau I-section ma ke kuʻi ʻana a i ʻole ka hoʻopaʻa ʻana i nā ʻāpana metala, hoʻokahi wale nō ʻāpana o ka metala.
Kaumaha
Ua oi aku ke kaumaha o na kaola H ma ka hoohalike ana me na kaola I.
Ka mamao mai ka hopena Flange a i ke kikowaena pūnaewele
Ma ka ʻāpana I, ʻoi aku ka liʻiliʻi o ka mamao mai ka hopena flange a i ke kikowaena pūnaewele, ʻoiai ma ka ʻāpana H, ʻoi aku ka kiʻekiʻe o ka mamao mai ka hopena flange a i ke kikowaena pūnaewele no ka ʻāpana like o ka I-beam.
Ka ikaika
Hāʻawi ka pahu h-section i ka ikaika no kēlā me kēia paona ma muli o kahi ʻāpana cross-section i ʻoi aku ka maikaʻi a me ka ratio ikaika-a-kaumaha maikaʻi.
ʻO ka maʻamau, ʻoi aku ka hohonu o nā kaola I-ʻāpana ma mua o ka laula, no laila maikaʻi loa lākou i ka lawe ʻana i ka ukana ma lalo o ke kīwī kūloko. Eia kekahi, ʻoi aku ka maʻalahi o ke kaumaha ma mua o nā kaola ʻāpana H, no laila ʻaʻole lākou e lawe i kahi haʻahaʻa nui e like me ka H-beams.
ʻoʻoleʻa
Ma keʻano laulā, ʻoi aku ka paʻakikī o nā kaola H-ʻāpana a hiki ke lawe i kahi ukana ʻoi aku ke kaumaha ma mua o nā kaola ʻāpana I.
ʻāpana keʻa
ʻO ka ʻāpana I-ʻāpana he ʻāpana kea haiki kūpono no ka lawe ʻana i ka haʻawe pololei a me nā koʻikoʻi tensile akā maikaʻi ʻole i ka wili.
I ka hoʻohālikelike ʻana, ʻoi aku ka nui o ka ʻāpana H beam ma mua o ka I beam, hiki iā ia ke hoʻopaʻa i ka ukana pololei a me nā koʻikoʻi tensile a pale aku i ka wili.
ʻO ka maʻalahi o ka welding
ʻOi aku ka maʻalahi o nā kaola ʻāpana H i ka weld ma muli o ko lākou mau flanges waho pololei ma mua o nā kaola ʻāpana I. ʻOi aku ka ikaika o ka lāʻau ʻāpana H ma mua o ka ʻāpana I- no laila hiki ke lawe i ka haawe nui.
Manawa o Inertia
ʻO ka Moment of Inertia no kahi lāʻau e hoʻoholo ai i kona hiki ke pale i ka piko. ʻO ke kiʻekiʻe, ʻoi aku ka liʻiliʻi o ke kukuna.
ʻOi aku ka laulā o nā kaola o ka ʻāpana H, ka ʻoʻoleʻa ʻaoʻao kiʻekiʻe, a ʻoi aku ka nui o ka manawa o ka inertia ma mua o nā kaola I-ʻāpana, a ʻoi aku ko lākou kūpaʻa i ka pelu ʻana ma mua o nā kaola I.
ʻO nā ʻāpana
Hiki ke hoʻohana ʻia ke kukui ʻāpana I no ka lōʻihi o ka 33 a hiki i ka 100 kapuaʻi ma muli o nā palena o ka hana ʻana, ʻoiai hiki ke hoʻohana ʻia ke kukui ʻāpana H no kahi lōʻihi a hiki i 330 kapuaʻi no ka mea hiki ke hana ʻia ma kekahi nui a kiʻekiʻe paha.
Hoʻokele waiwai
ʻO ke kukui ʻāpana H he ʻāpana ʻoi aku ka waiwai me ka hoʻomaikaʻi ʻana i nā waiwai mechanical ma mua o kahi kukui ʻāpana I.
Palapala noi
He kūpono nā kaola H-section no nā mezzanines, nā alahaka, nā paepae, a me ke kūkulu ʻana i nā hale noho maʻamau a me nā hale kalepa. Hoʻohana ʻia lākou no ke kolamu haʻahaʻa haʻahaʻa, trailer, a me ka moena kaʻa.
ʻO nā kaola I-section ka ʻāpana i hoʻohana ʻia no nā alahaka, nā hale kila i kūkulu ʻia, a me ka hana ʻana i nā papa kākoʻo a me nā kolamu no nā mea hoʻokiʻekiʻe, hoists a me nā hāpai ʻana, nā ala kaʻa, nā kaʻa, a me nā moena kaʻa.
