1. Wehewehena a me ke ʻano kumu

Nā ʻāpanaʻElua mau papa like, pae like o ka laulā like, e hāpai ana i ke kaumaha kulou mua.

Pūnaewele: ʻO ka ʻāpana kikowaena kū pololei e hoʻohui ana i nā flanges, e kūʻē ana i nā ikaika shear.

ʻO kakukuna HLoaʻa ka inoa 's mai kona ʻano ʻokiʻoki like me "H". ʻAʻole e like me kakukuna-I(I-beam), ʻoi aku ka laulā a me ka pālahalaha o kona mau flanges, e hāʻawi ana i ke kū'ē nui aʻe i nā ikaika kūlou a me ka torsional.

 

2. Nā Hiʻohiʻona ʻenehana a me nā Kikoʻī
Nā Mea Hana a me nā KūlanaʻO nā mea kila i hoʻohana pinepine ʻia e like me Q235B, A36, SS400 (kila kalapona), a i ʻole Q345 (kila haʻahaʻa-alloy), e kūlike ana me nā kūlana honua e like me ASTM a me JIS.

Ka laulā nui (nā kikoʻī maʻamau):

ʻĀpana	Pae palena
Kiʻekiʻe o ka pūnaewele	100–900 mm
Mānoanoa o ka pūnaewele	4.5–16 mm
Ka laulā o ka flange	100–400 mm
Mānoanoa o ka flange	6–28 mm
Ka lōʻihi	Maʻamau 12m (hiki ke hoʻopilikino ʻia)

Ka pōmaikaʻi o ka ikaikaHoʻonui ka hoʻolālā flange ākea i ka hoʻolaha ʻana o ka ukana, a ʻoi aku ka kiʻekiʻe o ke kū'ē ʻana ma mua o 30% ma mua o ko I-beam, e kūpono ana no nā hiʻohiʻona ukana kaumaha.

 

3. Nā Noi Nui
Nā Hana Kūkulu Hale: Hāʻawi nā kolamu i loko o nā hale kiʻekiʻe a me nā ʻauamo o ka hale i loko o nā hale hana ākea nui i ke kākoʻo ukana koʻikoʻi.

Nā Alahaka a me nā Mīkini KaumahaPono nā kaʻa crane a me nā kaʻa alahaka e kū i nā ukana hoʻoikaika a me ke kaumaha luhi.

ʻOihana a me ka HalihaliʻO nā papa moku, nā chassis kaʻaahi, a me nā kumu lako e hilinaʻi nei i ko lākou ikaika kiʻekiʻe a me nā waiwai māmā.

Nā Noi KūikawāHana ʻia nā koʻokoʻo hoʻohui ʻano-H i loko o nā ʻenekini kaʻa (e like me ka ʻenekini Audi 5-cylinder) mai ke kila chromium-molybdenum 4340 e kū i ka mana kiʻekiʻe a me ka wikiwiki.

 

4. Nā Pōmaikaʻi a me nā Hiʻohiʻona Koʻikoʻi
Hoʻokele waiwaiʻO ka lakio ikaika-i-ke kaumaha kiʻekiʻe e hōʻemi ana i ka hoʻohana ʻana i nā mea a me nā kumukūʻai holoʻokoʻa.

PaʻaʻO ka hui maikaʻi ʻana o nā waiwai flexural a me torsional e kūpono loa ia no nā hale ma nā wahi i maʻalahi i ka ōlaʻi a i ʻole nā ​​​​mea i kau ʻia i nā ukana makani kiʻekiʻe.

Kūkulu maʻalahi: Hoʻomaʻalahi nā pilina maʻamau i nā pilina i nā hale ʻē aʻe (e like me ka kuʻi ʻana a me ka hoʻopaʻa ʻana), e hoʻopōkole ana i ka manawa kūkulu.

Ka paʻaHoʻonui ka ʻōwili wela i ke kūpaʻa ʻana i ka luhi, e hopena ana i kahi ola lawelawe ma mua o 50 mau makahiki.

 

5. Nā ʻAno Kūikawā a me nā ʻAno like ʻole

Kaula Flange Laulā (Viga H Alas Anchas): Loaʻa nā flanges ākea, hoʻohana ʻia no nā kahua mīkini kaumaha.

Kukui HEBNā flanges parallel ikaika kiʻekiʻe, i hoʻolālā ʻia no nā ʻoihana nui (e like me nā alahaka kaʻaahi wikiwiki).

Kaula Laminated (Viga H Laminada)ʻŌwili wela ʻia no ka hoʻomaikaʻi ʻana i ka hiki ke hoʻopili ʻia, kūpono no nā mōlina kūkulu kila paʻakikī.
