He aha nā ʻano o nā ʻāpana HOLLOW STRUCTURAL?

He aha kaNā Māhele Hollow?

Hollow Structural Sections (HSS) e hōʻike ana i kahi papa o nā profile metala i hana maʻamau ʻia mai ke kila ʻōwili anuanu, i hana ʻia i loko o nā hoʻonohonoho tubular. ʻO kēia ʻano ʻokoʻa ka hopena i kahi ʻaoʻao hāmama a piha ʻole e holo ana ma ka lōʻihi holoʻokoʻa o ka pahu kila, a loaʻa iā lākou nā monikers ʻē aʻe "pahu pahu" a me "ʻāpana hollow." Ua piʻi nui ka lawe ʻia ʻana o HSS ma muli o kona ʻano malleable, versatility, a me ka paʻa paʻa o ka hoʻolālā ʻana, e hoʻoikaika nui ai i nā manaʻo hoʻolālā noʻonoʻo.

Nā ʻano o nā ʻāpana Hollow Structural:

Loaʻa maʻamau nā ʻāpana Hollow Structural i ʻekolu mau hoʻonohonoho kumu: ʻāpana ʻāpana ʻāpana ʻehā (RHS), ʻāpana ʻāpana kūhāhā (SHS), a me nā ʻāpana ʻāwaha pōʻai (CHS). Hāʻawi kēlā me kēia ʻano o ka ʻāpana hollow i nā pono, nā waiwai, a me nā noi.

1. Nā ʻāpana hāhāhāhā (SHS):

Loaʻa iā SHS kahi ʻāpana kūhā like a hoʻohana pinepine ʻia i ke kūkulu ʻana i nā hale kahi i makemake ʻia ai nā ʻano huinahā. Hoʻohana maʻamau ʻia lākou i ke kūkulu ʻana i nā papa, nā kolamu kākoʻo, a me nā noi hoʻolālā ʻē aʻe.

2. Rectangular Hollow Sections (RHS):

Loaʻa i ka RHS kahi ʻāpana ʻāpana ʻehā a hoʻohana ʻia i nā kūlana i kūpono ke ʻano ʻāpana ʻehā. E like me SHS, hoʻohana maʻamau ʻia ʻo RHS i ke kūkulu ʻana a me ke kūkulu ʻana no nā mea hana.

3. Nā Māhele Hollow Poʻai (CHS):

Loaʻa i ka CHS kahi ʻāpana keʻa pōʻai a hoʻohana pinepine ʻia i nā noi i ʻoi aku ka maikaʻi o ke ʻano pōʻai, e like me ke kūkulu ʻana i nā kolamu, pole, a me nā hale cylindrical ʻē aʻe. ʻIke ʻia ʻo CHS no kāna hoʻohana pono ʻana i nā mea i ke kūʻē ʻana i nā ukana torsional.

Hollow Structural Sections (HSS) i ka ʻoihana metala ke kaena nei i kekahi mau hiʻohiʻona kaulana:

1. Nā mea hoʻohana maʻamau ma nā ʻoihana:

Hoʻohana nui ʻia ʻo HSS no kona hiki ke hoʻomanawanui i nā ukana nui i nā lōʻihi lōʻihi. Hoʻolilo kēia versatility i mea makemake no nā papahana e koi ana i ka paʻa paʻa. Hiki i ka hiki ke hoʻololi i ka HSS i kona hoʻohana ʻana i nā kaiapuni like ʻole, e lilo ia i koho maikaʻi loa no nā papahana e koi ana i ke kūpaʻa kūʻē i nā mea ʻino a ʻino paha.

2.High Load-Bearing Capability:

ʻO kekahi o nā hiʻohiʻona koʻikoʻi o ka HSS ʻo ia kona hiki ke kū i nā haʻahaʻa kiʻekiʻe, e lilo ia i koho hilinaʻi no nā noi hoʻolālā kahi i ʻoi aku ka ikaika.

3. Kūpono kaiapuni ākea:

Hōʻike ka HSS i ke kūpaʻa ma nā ʻano kaiapuni, e ʻae ana i kona hoʻohana ʻana i nā ʻano like ʻole. He mea kūpono kēia ʻano no nā papahana i ʻike ʻia i nā kūlana corrosive a paʻakikī paha.
