Nūhou - Ua wehewehe ʻia ke Kanal UPN: Manaʻo, Profile, ʻAno a me nā hoʻohana i ke kūkulu ʻana i ke kila

I ke kūkulu ʻana i ke kila a me ka ʻākoakoa ʻoihana, he mau koho kaulana nā ʻāpana kahawai no ka ikaika, ka hiki ke hoʻololi a me ka maʻalahi o ka hoʻohana. I waena o lākou, ʻo kaKanal UPNʻo ia kekahi o nā ʻaoʻao kahawai maʻamau ʻEulopa kaulana loa. Ke ʻike nei i ka UPN a me kāna mau noi, a pehea ka ʻokoʻa o UPN mai nā mea ʻē aʻeNā kahawai Uhiki ke kōkua i nā ʻenekinia, nā mea kūkulu hale a me nā mea kūʻai mai no ke koho ʻana i ka ʻāpana kila kūpono.

He aha ka manaʻo o UPN ma ke kila?

Ua puka mai ka huaʻōlelo UPN mai Farani mai:
U = ʻāpana U (U geformter Querschnitt)
P = Profile (ʻāpana)
N = Maʻamau (moʻo maʻamau)

No laila, pili ʻo UPN i kahi "ʻāpana kahawai maʻamau U."
Ua hana ʻia ia e kūlike me nā kūlana ʻEulopa (no ka laʻana EN 10279 / DIN 1026) a no ka hui kahawai "parallel flange" kuʻuna.

Loaʻa i nā kahawai UPN:
ʻO kahi ʻāpana kea U-ʻano
Ua hoʻopololei iki ʻia nā flanges o loko (ʻaʻole like loa)
Ua hoʻohālikelike ʻia ke kiʻekiʻe, ka laulā o ka flange a me ka mānoanoa.

Penei ka wehewehe pinepine ʻia ʻana o lākou:
UPN 80, UPN 100, UPN 160, UPN 200a pēlā aku, kahi e hōʻike ai ka helu i ke kiʻekiʻe maʻamau i mm.

He aha ka UPN Profile o kahi Beam?

ʻO kaʻIkepili UPNheKanal ʻano-Ume nā mea i lalo:
hoʻokahi pūnaewele kū pololei (ʻāpana kū waena)
ʻElua mau flanges ma kekahi ʻaoʻao e kūlou ana i waho.
Nā flanges i hoʻopaʻa ʻia ma ko lākou ʻili o loko

Nā ʻano koʻikoʻi o ka ʻaoʻao pilikino:
Hāmama (ʻaʻole i pani ʻia ka pahu a i ʻole ka paipu)
Ikaika kūlou kū pololei maikaʻi
He mea maʻalahi ke hoʻopili ʻia me nā bolts, welds, a me nā brackets
ʻOi aku ka māmā ma mua o nā kaola I a i ʻole H o ke kiʻekiʻe like

Ma muli o kēia ʻano, kūpono nā ʻāpana UPN no nā ʻōnaehana lua, nā joists a me nā ʻāpana kākoʻo, kahi i pono ʻole ai ka mana piha o kahi I-beam.

He aha nā mea e hoʻohana ʻia ai nā kahawai UPN?

He mea kaulana nā ʻikepili UPN i ke kūkulu ʻana i nā mīkini, nā kaʻa a me nā lako hana ʻoihana e like me:

Ke Kūkulu ʻana a me ke Kūkulu ʻana
Nā mōlina kila a me nā mōlina liʻiliʻi
Nā ʻūpā paia a me ka hale
Nā kaula alapiʻi
Nā lintels a me nā kaola liʻiliʻi

Nā Hoʻohana ʻOihana a me nā Mekanika
Nā mōlina mīkini a me nā kumu
Nā kākoʻo lako
Nā ʻano hana hoʻoili
Nā pā a me nā kahua

ʻOihana Hana a me ka Hana ʻana
Nā lālā lua o ke alahaka
Nā pale lima a me nā pale kaua
Nā pale kila a me nā mōlina

ʻO kā lākou mau pono:
ʻOki maʻalahi, ʻeli, a me ka kuʻihao
Ka lakio ikaika-a-kaumaha maikaʻi
ʻOi aku ka hoʻokele waiwai ma mua o nā ʻāpana kaola kaumaha
Loaʻa koke i nā nui maʻamau

He aha nā ʻano like ʻole o nā U Channels?

Ua māhele ʻia ke kila U channel i kekahi mau ʻano maʻamau o ke ao holoʻokoʻa:

Nā Kanal UPN (Kūlana ʻEulopa)
Nā flanges kūloko i hoʻopaʻa ʻia
Hoʻonohonoho ʻia e like me EN/DIN
Nā nui e like me UPN 80, 100, 120, 160, 200, a pēlā aku.

Nā Kaha UPE (ʻEulopa Parallel Flange)
Ua like maoli nā flanges
ʻOi aku ka wikiwiki no ka hoʻopaʻa ʻana a me nā pilina
I kekahi manawa ua mālama ʻia i loko o ka hoʻolālā kila hou

Nā Kanal UPA
ʻAno māmā o UPN
Hoʻohana ʻia i ka wā e lawa ai ka lawe ʻana i ka ukana liʻiliʻi

Nā Kahawai Maʻamau ʻAmelika (Nā Kahawai C)
ʻO ke ʻano o "C" he ʻāpana kahawai ia a he huahana maʻamau ia ma ʻAmelika Hui Pū ʻIa.
Ua kapa ʻia ʻo C6x8.2, C8x11.5 etc.
E kūlike me ASTM/AISC

Nā Kūlana Kepanī a me ʻĀkia
Nā kahawai JIS (e like me C100, C150)
Nā kahawai GB ma Kina

He ʻokoʻa iki ke ʻano geometry, nā ʻae ʻana, a me ka hana ukana o nā ʻano āpau, a no laila pono nā ʻenekinia e koho i ke kūlana kūpono no kā lākou papahana e pili ana i nā code kūloko a me nā kikoʻī o ka papahana.

No ke aha he mea nui nā kahawai UPN i kēia lā

I kēia mau lā, ʻoi aku ka makemake o nā ʻāpana flange parallel akā kaulana mau nā kahawai UPN no ka mea:

kūpono ke kumukūʻai a loaʻa koke
maʻalahi e hana a hoʻonohonoho
Kūpono no nā ukana kūkulu māmā a me waena
Kūlike me nā ʻōnaehana ʻEulopa maʻamau he nui

Mai nā hale a i nā mōlina mīkini, he hopena hilinaʻi mau nā kahawai UPN a he hopena kūpono hoʻi no ka ʻenekinia kūkulu kila.

E pili ana i nā lawelawe a ka Royal Steel Group

Inā ʻoe e ʻimi nei i ke kūlana kiʻekiʻe, kūlana maʻamauUPN, UPE, a i ʻole nā ʻano ʻē aʻeNā kahawai U, Pūʻulu kila aliʻiHāʻawi mākou i kahi laulā piha o nā huahana. Loaʻa iā mākou kahi waihona nui a me ke kākoʻo ʻana i ka hoʻopilikino ʻana i nā nui like ʻole a me nā mea hana, kūpono no nā ʻano papahana like ʻole e pili ana i ke kūkulu ʻana, nā lako ʻoihana, nā alahaka, a me nā ʻano hana mīkini. Inā no nā ʻano hana māmā a i ʻole nā hana kaumaha, hiki iā mākou ke hāʻawi i ke kila e kūlike me nā kūlana ʻEulopa a me nā kikoʻī honua. ʻO ke koho ʻana iā Royal Steel Group ʻo ia hoʻi ka hauʻoli i ka lawe wikiwiki ʻana, nā ʻōlelo aʻoaʻo loea, a me ka lawelawe ma hope o ke kūʻai aku maikaʻi loa, e hōʻoiaʻiʻo ana i ka hoʻopau maʻalahi a me ka maikaʻi o kāu mau papahana kūkulu kila.
