Nūhou - Nā Kikoʻī, nā Mea Hana a me nā Noi o ka ASTM H Beam

ʻOiai ke piʻi wikiwiki nei ka hoʻopukapuka kālā ʻana i nā ʻoihana honua ma ʻAmelika ʻĀkau, ʻAmelika Latina, a me Asia Hikina Hema, ʻo kaASTM H Beamaia nō ia ma waena o nā ʻāpana kila kūkulu kaulana loa i hoʻohana ʻia i ke kūkulu ʻana i nā ʻoihana kalepa, ʻoihana, a me nā ʻoihana kūkulu. ʻO ke kaumaha kiʻekiʻe, ke kūpaʻa maikaʻi o ka ana a kūlike me ke kūlana ʻAmelika. Hoʻohana nui ʻia ia i nā ʻōnaehana kūkulu e hāʻawi ana i ka hana kiʻekiʻe a puni ka honua.

ASTM-A572-Gr50-A992-Flange-ākea-Ipe-270-Ipe-300-Heb-260-Hea-200-Kūkulu-ʻAoʻao-Hoʻokahi (1)

Nā Kikoʻī ASTM Koʻikoʻi

ʻO nā kaola ASTM H (ʻike ʻia hoʻi he mau kaola flange ākea) e hana pinepine ʻia e like me nā kūlana ma lalo nei:

ASTM A36 Kukui H– Ke kila kalapona kūkulu maʻamau no nā hale a me nā papahana ʻoihana māmā
ASTM A572 Kukui H– Ke kila HSLA me ka lakio ikaika-a-kaumaha i hoʻomaikaʻi ʻia
ASTM A992 Kukui H– Papa makemake ʻia no nā kaola flange ākea kūkulu ma ka mākeke US
ASTM A588 Kukui H– Ke kila kūpaʻa i ka palaho no nā alahaka a me nā hale o waho

I waena o kēia mau mea, ʻo ke ʻano maʻamau loa ma ʻAmelika Hui Pū ʻIaKaula flange ākea ASTM A992, nona ka ikaika kaulike loa, ka hiki ke hoʻopili ʻia a me nā waiwai ductility.

Nā Waiwai Mea a me ka Hana Mekanika

Nā Noi Nui

Nā ʻano mīkini maʻamau (ʻokoʻa ma muli o ka papa):

Ikaika Hāʻawi: 250–345 MPa (36–50 ksi a ʻoi aku)
Ikaika Hoʻopaʻa: 400–550 MPa
ʻO ka weldability maikaʻi loa a me ke ʻano hana
Ke kūpaʻa ikaika i ke kūlou ʻana a me ke kaomi ʻana

Hāʻawi ka ʻāpana keʻa H-ʻano i:

1. Modulus ʻāpana kiʻekiʻe

2. Ka hoʻokaʻawale ʻana i ka ukana kūpono

3. Hoʻemi ʻia ka hoʻohana ʻana i ke kila i hoʻohālikelike ʻia me nā I-beams kuʻuna

4. Hana maikaʻi loa i nā kūlana seismic a me ka ukana makani

Hopena o ka ASTM H Beam

ʻO ASTM H Beam a i ʻole Wide Flange Beam kahi huahana alakaʻi i ke kūkulu ʻana i ke kila i kēia lā. Me ka nānā ʻole inā he hale waihona ʻoihana ka papahana, hale kila kalepa, a i ʻole ʻenekinia alahaka, hāʻawi nā ASTM structural H beams i ka ikaika, ka hilinaʻi a me ka hoʻokō honua.

I nā mea hoʻokuʻu aku i ke kila a me nā mea hana hale, he mea nui iā lākou ke koho i kahi mea hoʻolako beam H hilinaʻi e hiki ke hoʻokō i nā koi kūlana kiʻekiʻe a hōʻoia ʻia e nā pae hoʻohālikelike honua e hoʻomau i kā lākou hoʻokūkū i ka makahiki 2026 a ma waho aku.
