ʻO ka wehewehe pōkole:
Hoʻokaʻawale nui ʻia ʻo I-beam i ka I-beam maʻamau, I-beam māmā a me I-beam ākea ākea.E like me ka lākiō kiʻekiʻe o ka flange i ka pūnaewele, ua māhele ʻia i ka laulā, waena a me ka haiki flange I-beams.ʻO nā kikoʻī o nā mea mua ʻelua he 10-60, ʻo ia hoʻi, ʻo ke kiʻekiʻe e pili ana he 10 cm-60 cm.Ma ke kiʻekiʻe like, ʻo ka I-beam māmā he liʻiliʻi liʻiliʻi, pūnaewele lahilahi a me ke kaumaha māmā.Hōʻike ʻia ʻo I-beam ākea ākea, ʻo ia hoʻi ʻo H-beam, e nā wāwae ʻelua like ʻole a ʻaʻohe inclination ma ka ʻaoʻao o loko o nā wāwae.No ke kila ʻāpana waiwai a ua ʻōwili ʻia ma luna o ka wili honua kiʻekiʻe ʻehā, no laila ua kapa ʻia ʻo ia ʻo "universal I-beam".ʻO ka I-beam maʻamau a me ka māmā I-beam ua hoʻokumu i nā kūlana aupuni.
Nā hiʻohiʻona noi
Inā he mea maʻamau a māmā paha ke kila I-ʻāpana, no ka mea he kiʻekiʻe a haiki ka nui o ka ʻāpana, ʻokoʻa loa ka manawa o ka inertia o nā koʻi nui ʻelua o ka ʻāpana, no laila hiki ke hoʻohana pololei ʻia no nā lālā i kulou i ka mokulele o kā lākou pūnaewele a i ʻole nā lālā i hoʻoikaika ʻia i ka lattice.ʻAʻole kūpono ia no nā lālā compression axial a i ʻole nā lālā me ke kuʻekuʻe kū pololei i ka mokulele pūnaewele, kahi i kaupalena ʻia ai i ke ʻano o ka noi.Hoʻohana nui ʻia ka I-beam i nā hale a i ʻole nā hale metala ʻē aʻe.
Ma muli o ke kiʻekiʻe a me ka ʻāpana ʻāpana o ka I-beam maʻamau a me ka māmā I-beam, ʻokoʻa loa ka manawa o ka inertia o nā koʻi nui ʻelua o ka pauku, kahi i kaupalena ʻia ai i ke ʻano o ka noi.E koho ʻia ka hoʻohana ʻana i ka I-beam e like me nā koi o nā kiʻi hoʻolālā.
I ke koho ʻana i ka I-beam i ka hoʻolālā hoʻolālā, e koho ʻia ka I-beam kūpono e like me kona mau waiwai mechanical, waiwai kemika, weldability a me ka nui o ke kūkulu.
