Laulā I-kuanala laula
Hoʻokaʻawale nui ʻia nā I-beams i nā I-beam maʻamau, nā kukui I-beams a me nā I-beam ākea ākea.E like me ke kiʻekiʻe lākiō o ka flange i ka punaewele, ua maheleia i ka laula, waena, a haiki laula flange I-beams.ʻO nā kikoʻī hana mua ʻelua he 10-60, ʻo ia hoʻi, ʻo ke kiʻekiʻe e pili ana he 10 cm-60 cm.Ma ke kiʻekiʻe hoʻokahi, loaʻa i ka I-beam māmā nā flanges haiki, nā pūnaewele lahilahi a me ke kaumaha māmā.Ua kapa ʻia ʻo I-beam ākea ākea H-beam, a ua ʻike ʻia kona ʻāpana keʻa e nā wāwae like ʻole a ʻaʻohe piʻi ma ka ʻaoʻao o loko o nā wāwae.Aia ia i ke kila ʻāpana waiwai, i ʻōwili ʻia ma luna o ka wili honua ʻehā kiʻekiʻe, no laila ua kapa ʻia ʻo ia ʻo "universal I-beam".Ua lilo nā I-beam maʻamau a me nā kukui-duty I-beam i mau kūlana aupuni.
ʻAʻole paha he mea maʻamau a māmā paha ke kila I-like, no ka mea he kiʻekiʻe a haiki ka nui o ke keʻa, ʻokoʻa ka manawa o ka inertia o nā koʻi nui ʻelua o ka ʻāpana, no laila hiki ke hoʻohana pololei ʻia. no ka piko ʻana i ka mokulele o kāna pūnaewele.ʻO nā ʻāpana a i ʻole e hoʻohui iā lākou i mau ʻāpana hoʻoikaika ikaika ʻano lattice.ʻAʻole kūpono i ka hoʻohana ʻana i nā ʻāpana compression axial a i ʻole nā mea e kū pono ana i ka mokulele o ka pūnaewele, i curved pū kekahi, kahi i kaupalena ʻia ai kāna palapala noi.Hoʻohana nui ʻia nā I-beams i ke kūkulu ʻana a i ʻole nā mea metala ʻē aʻe.
ʻO nā kaola I maʻamau a me nā kukui I-ʻoihana māmā he ʻano kiʻekiʻe a haiki i nā ʻāpana keʻa, no laila, ʻokoʻa loa nā manawa o ka inertia o nā koʻi nui ʻelua o nā ʻāpana keʻa, e kaupalena ana i kā lākou noi.Pono e koho ʻia ka hoʻohana ʻana i ka I-beam e like me nā koi o nā kiʻi hoʻolālā.
ʻO ke koho ʻana i ka I-beam i ka hoʻolālā hoʻolālā e hoʻokumu ʻia ma kāna mau waiwai mechanical, nā waiwai kemika, weldability, ka nui o ka hale, a me nā mea ʻē aʻe e koho i kahi I-beam kūpono no ka hoʻohana ʻana.
