Kaula H kila, i kapa ʻia no ko lākou ʻāpana keʻa "H", he mea kila kūpono loa a hoʻokele waiwai hoʻi me nā pono e like me ke kūpaʻa kūlou ikaika a me nā ʻili flange like. Hoʻohana nui ʻia lākou ma nā ʻano like ʻole, me ke kūkulu ʻana, nā alahaka, a me ka hana mīkini. Ma waena o nā kūlana H-beam he nui, kū nā H-beams i kuhikuhi ʻia ma ASTM A992 no kā lākou hana koʻikoʻi.
ʻO nā kaola H-ASTM A992 ka kila kūkulu i hoʻohana nui ʻia ma nā hale o ʻAmelika Hui Pū ʻIa, e hāʻawi ana i ka ikaika kiʻekiʻe a me ka paʻakikī maikaʻi loa. Me ka ikaika hua liʻiliʻi o 50 ksi (ma kahi o 345 MPa) a me ka ikaika tensile ma waena o 65 a me 100 ksi (ma kahi o 448 a me 690 MPa), hiki iā lākou ke kū i nā ukana kaumaha a hōʻike i ka weldability maikaʻi loa a me ke kū'ē seismic. ʻO kēia ka mea e hana aiNā kaola H ASTM A992ka mea i koho ʻia no nā papahana koʻikoʻi e like me nā hale kiʻekiʻe a me nā alahaka nui.
Ma waena o nā nui like ʻole o ka ASTM A992 H-beam, ʻo 6 * 12 a me 12 * 16 nā nui maʻamau.
He ʻano haiki ko nā laulā flange o ka 6*12 Metal H Beam a he kiʻekiʻe kūpono, e hāʻawi ana i nā noi hoʻokele waiwai a me nā hana kūpono maikaʻi loa. I ka ʻoihana kūkulu hale, hoʻohana pinepine ʻia lākou i nā ʻāpana kūkulu e like me nā kaola lua a me nā purlins i nā hale noho a me nā hale kalepa, e kaʻana like ana i nā ukana hale a me ka hōʻoia ʻana i ke kūpaʻa o ka hale. I nā hale hana ʻoihana liʻiliʻi, hoʻohana pinepine ʻia nā kaola H 6*12 e kākoʻo i nā hale o ka hale a hoʻokō i nā koi ukana.
Hāʻawi nā H-beam ʻōwili wela 12*16 i nā ana ʻāpana ʻoi aku ka nui a me ka hiki ke lawe ukana kiʻekiʻe. I ke kūkulu ʻana i ke alahaka nui, lawelawe lākou ma ke ʻano he mau kaola lawe ukana mua, e omo ana i nā ukana kaʻa a me nā pilikia o ke kaiapuni kūlohelohe, e hōʻoiaʻiʻo ana i ka ikaika a me ke kūpaʻa o ke alahaka. I loko o nā hale kiʻekiʻe loa, hoʻohana pinepine ʻia nā H-beam 12*16 ma nā wahi koʻikoʻi e like me nā paipu koʻikoʻi a me nā kolamu mōlina, e hāʻawi ana i ke kākoʻo ikaika no ka hale holoʻokoʻa a pale iā ia mai nā pōʻino kūlohelohe e like me ka makani a me nā ōlaʻi. Eia kekahi, he kuleana koʻikoʻi ko nā H-beam 12*16 i nā papahana nui e like me nā kahua lako ʻoihana nui a me nā kikowaena awa.
I ka pōkole, ʻo nā ASTM A992 H-beams, me kā lākou hana maikaʻi loa a me nā ʻano nui like ʻole, he kuleana koʻikoʻi ia i nā papahana kūkulu like ʻole. ʻO nā 6 * 12 a me 12 * 16 H-beams, me ko lākou mau ʻano kūikawā, e hoʻokō i nā pono like ʻole o nā papahana like ʻole, e hoʻokele ana i ka hoʻomohala mau ʻana o ke kūkulu ʻenekinia hou.
Hōʻike ka ʻike ma luna nei i nā ʻano o ka ASTM A992 Carbon Steel H Beam, mai ka hana a hiki i ka hoʻohana. Inā makemake ʻoe e hoʻohui i nā kikoʻī ʻē aʻe a i ʻole nā hiʻohiʻona noi, e ʻoluʻolu e hoʻomaopopo iaʻu.
