Hoʻolauna mea H-beam

ʻO ka H-beam ma ke ʻano he I-beam a i ʻole ke kila kila honua, he ʻano hoʻokele waiwai a maikaʻi hoʻi me ka hoʻoili ʻia ʻana o ka ʻāpana cross-sectional a me ka ratio ikaika-a-kaumaha kūpono. Loaʻa kona inoa mai kona ʻano cross-sectional e like me ka leka Pelekane "H".

ʻO ka hoʻolālā ʻana o kēia kila e loaʻa iā ia ke kūpaʻa kūlou maikaʻi ma nā ʻaoʻao he nui, a i ka manawa like, maʻalahi ke kūkulu ʻana, hiki ke mālama pono i nā kumukūʻai a hoʻemi i ke kaumaha o ka hale. ʻO nā mea hana o ka H-beam ka mea maʻamau i Q235B, SM490, SS400, Q345B, a me nā mea ʻē aʻe, e hoʻonui ai i ka H-beam i ka ikaika o ka hoʻolālā a me ka hiki ke hoʻolālā. Ma muli o kāna flange ākea, pūnaewele lahilahi, nā kikoʻī like ʻole a me ka hoʻohana maʻalahi, hiki i ka hoʻohana ʻana o H-beam i nā hale truss like ʻole ke mālama i ka 15% a 20% o ka metala.

Eia kekahi, ʻelua mau ala nui no ka hana ʻana i ka H-beam: welding a rolling. Hana ʻia ʻo Welded H-beam ma ke ʻoki ʻana i ke kaula i kahi ākea kūpono a hoʻopaʻa pū ʻia ka flange a me ka pūnaewele ma kahi hui hoʻomau mau. Hoʻohana nui ʻia ʻo Rolled H-beam i ka hana wili kila hou me ka hoʻohana ʻana i nā wili wili honua, hiki ke hōʻoia i ka pololei o ka dimensional a me ka kūlike o ka hana o ka huahana.
Hoʻohana nui ʻia ka H-beam i nā ʻano hale kīwila a me nā hale ʻoihana, nā mea kanu ʻoihana nui a me nā hale kiʻekiʻe o kēia wā, a me nā alahaka nui, nā mea kaumaha, nā alaloa, nā papa moku, a me nā mea ʻē aʻe. nā mea kanu ʻoihana ma nā wahi me nā hana seismic pinepine a ma lalo o nā kūlana hana wela kiʻekiʻe.
