1. Wehewehe a me ka Papahana Kumu

ʻO nā lehelehe: ʻElua mau papa ʻālike like ʻole o ka laula like ʻole, e amo ana i ka haʻawe piko mua.

Pūnaewele: ʻO ka ʻāpana kikowaena kū i ka hoʻopili ʻana i nā flanges, e kūʻē ana i nā ikaika ʻoki.

ʻO kaH-kuola'O ka inoa mai kona "H"-like cross-sectional shape. ʻAʻole like me kahiI-kuola(I-beam), ʻoi aku ka laulā a me ka palahalaha o kona mau flanges, e hāʻawi ana i ke kūpaʻa ʻoi aʻe i nā ikaika kulou a me ka torsional.

 

2. Nā hiʻohiʻona ʻenehana a me nā kikoʻī
Nā mea a me nā kūlana: ʻO nā mea kila maʻamau ka Q235B, A36, SS400 (he kila kalapona), a i ʻole Q345 (he kila haʻahaʻa haʻahaʻa), e like me nā kūlana honua e like me ASTM a me JIS.

Laulā nui (nā kikoʻī maʻamau):

Māhele	Laulā palena
Kiʻekiʻe pūnaewele	100–900 mm
Mānoanoa pūnaewele	4.5–16 mm
Laulā flange	100–400 mm
Mānoanoa flange	6–28 mm
Ka lōʻihi	12m maʻamau (hiki ke hoʻololi ʻia)

Pono ikaika: Hoʻonui ka hoʻolālā flange ākea i ka hāʻawi ʻana i ka ukana, a ʻoi aku ka ʻoi aku o ke kūpaʻa kūlou ma mua o 30% kiʻekiʻe ma mua o ka I-beam, i kūpono ia no nā hiʻohiʻona kaumaha.

 

3. Nā noi nui
Nā Kūlana Kūlana: ʻO nā kolamu ma nā hale kiʻekiʻe a me nā ʻūhā o ka hale ma nā hale hana nui e hāʻawi i ke kākoʻo ukana kumu.

Na Alahaka a me na Mekini Kaumaha: Pono nā kāʻei o ka crane a me nā kaula alahaka e kū i nā haʻawe ikaika a me ka luhi luhi.

ʻOihana a me ka lawe ʻana: Ke hilinaʻi nei nā papa moku, nā chassis kaʻaahi, a me nā kumu lako i ko lākou ikaika kiʻekiʻe a me nā waiwai māmā.

Nā noi kūikawā: ʻO nā lāʻau hoʻohui H-type i nā ʻenekini kaʻa (e like me ka ʻenekini Audi 5-cylinder) i hana ʻia mai 4340 chromium-molybdenum kila e kū i ka mana kiʻekiʻe a me ka wikiwiki.

 

4. Nā Pono a me nā hiʻohiʻona kumu
Hoʻokele waiwai: ʻO ka lakio ikaika-a-kaumaha kiʻekiʻe e hōʻemi ana i ka hoʻohana waiwai a me nā kumukūʻai holoʻokoʻa.

Paʻa: Hoʻohui maikaʻi ʻia nā waiwai flexural a torsional maikaʻi loa ia no nā hale ma nā wahi hiki i ke ōlaʻi a i ʻole nā ​​mea e pili ana i nā hawewe makani kiʻekiʻe.

Hana maʻalahi: Hoʻomāmā nā pilina maʻamau i nā pilina me nā hale ʻē aʻe (e like me ka welding a me ka bolting), e hoʻopōkole i ka manawa hana.

Ka lōʻihi: Hoʻonui ka wela wela i ke kūpaʻa luhi, ka hopena i ke ola lawelawe ʻoi aku ma mua o 50 mau makahiki.

 

5. Nā ʻano kūikawā a me nā ʻano like ʻole

ʻO ka lāʻau lapaʻau ākea (Viga H Alas Anchas): Loaʻa nā flanges ākea, hoʻohana ʻia no nā kumu mīkini kaumaha.

HEB Kaola: ʻO nā flanges parallel ikaika kiʻekiʻe, i hoʻolālā ʻia no nā ʻoihana nui (e like me nā alahaka kaʻa kiʻekiʻe).

Kukui Lamina (Viga H Laminada): Hoʻowili wela no ka hoʻomaikaʻi ʻana i ka weldability, kūpono no nā papa hana kila paʻakikī.
