He ʻokoʻa koʻikoʻi nā ʻano H-beam maʻamau ʻEulopa HEA a me HEB i ke ʻano o ka ʻāpana kea, ka nui a me ka hoʻohana ʻana.
Moʻo HEA
He flange ākea ʻōwili wela ʻo HEAkukuna Hma ke kūlana ʻEulopa, me ke ʻano ʻāpana keʻa "H", ʻelua mau helehelena hana like (nā pūnaewele) a me ʻelua mau papa flange. ʻIke ʻia ke ʻano HEA H-beam e nā flanges haiki a me ke kiʻekiʻe nui, kahi e kūpono ai no nā hanana me nā manawa kūlou nui, e like me nā alahaka, nā hale kiʻekiʻe, a pēlā aku.1. Ma ke ʻano kikoʻī, hoʻohana pinepine ʻia nā kila moʻo HEA no nā hale e pono ai ka ikaika a me ka paʻakikī kiʻekiʻe, e like me nā kiʻi hale e hana maikaʻi ana ma lalo o nā ukana kū pololei a me ka pae.
Moʻo HEB
I ka hoʻohālikelike ʻana, ʻo ke ʻano HEB H-beam he ʻano wela-wili ʻia hoʻi ka ribbed wide-flange H-beam ma lalo o ke kūlana ʻEulopa, akā ʻokoʻa kona ʻano mai ka HEA. ʻOi aku ka liʻiliʻi o ka ʻāpana cross-sectional o ke ʻano HEB H-beam ma mua o ka HEA, akā ʻoi aku ka laulā o kona flange a ʻoi aku ka mānoanoa o ka pūnaewele, e hāʻawi ana i ka hana compressive ʻoi aku ka maikaʻi o ka HEB H-beam a kūpono no nā hiʻohiʻona noi e pono ai ka ʻoi aku ka paʻakikī o ka flange2. ʻO ke ʻano kēia i kekahi mau hihia, ʻoiai ʻo kaʻāpana keaʻOi aku ka liʻiliʻi o ka ʻāpana o HEB, hiki iā ia ke hāʻawi i ke kākoʻo ikaika ma muli o kona flange ākea a me ka pūnaewele mānoanoa.
1. Nā ana ʻāpana kea a me nā ʻano geometric
•Hea moʻo (kukui H māmā)
▪Nā ʻāpana ololi a lahilahi (flanges) a me nā pūnaewele lahilahi (nā papa kū waena).
▪Māmā ke kaumaha no kēlā me kēia anakahi lōʻihi a me ka ʻāpana ʻāpana liʻiliʻi.
▪ʻO ka manawa haʻahaʻa o ka inertia (ke kū'ē kūlou) a me ka modulus ʻāpana, kūpono no nā hiʻohiʻona ukana waena.
•Moʻo HEB (kukui H maʻamau)
▪Nā flanges ākea a mānoanoa a me nā pūnaewele mānoanoa.
▪ʻOi aku ke kaumaha o ka ʻāpana a me ka nui o ka ʻāpana ʻokiʻoki.
▪ʻOi aku ka kiʻekiʻe o ka manawa o ka inertia a me ka modulus ʻāpana, ʻoi aku ka ikaika o ke kūlou a me ke kūpaʻa ʻana, kūpono no nā hale kaumaha
3. Nā waiwai mechanical a me nā hiʻohiʻona noi
HEA
▪Kūpono no nā ukana māmā a waena, e like me nā mōlina mea kanu māmā, nā kahua liʻiliʻi a i ʻole nā hale i lawe ʻole i ka ukana.
▪Hoʻokele waiwai maikaʻi, mālama i nā kumukūʻai lako.
HEB
▪Hoʻohana ʻia i nā kūlana kaumaha, e like me nā kaola nui o ke alahaka, nā kolamu hale kiʻekiʻe a i ʻole nā kākoʻo mīkini kaumaha.
▪ʻOi aku ka paʻakikī a me ka ikaika, akā ʻoi aku ke kumukūʻai o nā mea.
4. Nā moʻo H-beam ʻEulopa ʻē aʻe
▪Moʻo HEM: nā flanges a me nā pūnaewele mānoanoa, i hoʻolālā ʻia no nā ukana koʻikoʻi (e like me nā kahua lako ʻoihana kaumaha).
▪Moʻo IPN/IPE: ʻAno like me HEA/HEB, akā me ka hoʻolālā flange like (ʻaʻohe piʻo ma ka ʻaoʻao o loko o ka flange).
Nā wahi noi
Ma muli o nā ʻokoʻa o nā ʻano i luna, ʻo ka hoʻohana ʻana o nā ʻano HEA a me HEB H-beams i ka ʻenekinia maoli e kālele ana hoʻi i nā ʻano like ʻole. ʻOi aku ka kūpono o ka HEA H-beam no nā wahi e pono ai ke kūpaʻa kiʻekiʻe a me ka ikaika kiʻekiʻe, e like me ka ʻōnaehana kākoʻo kahua o nā hale nui a i ʻole ka paipu kumu o nā hale kiʻekiʻe. ʻO ka HEB H-beam, ma muli o kona laulā flange nui a me ka pūnaewele mānoanoa, hana maikaʻi loa i ka wā e kau ʻia ai nā ukana kaomi nui. No laila, hoʻohana pinepine ʻia ia i loko o ke kahua kahua o nā mīkini kaumaha a i ʻole nā hale hana ʻoihana me nā koi kiʻekiʻe no ka hiki ke hāpai.
