E like me kā kākou ʻike,ʻāpana hollow steelhe mea hale maʻamau no nā hale kila. Maopopo anei iā ʻoe ka nui o nā ʻano pauku o nā lālā hale kila kiʻekiʻe? E nānā kākou i kēia lā.
1、 Axially stressed lālā
ʻO ka lālā axial ikaika e pili ana i ka lālā e lawe ana i ka axial tension a i ʻole ke kaomi axial, ʻo ia ka mea maʻalahi loa i waena o nā lālā.
2、 Lahui flexural
Hoʻopili ʻia nā lālā kulou i nā manawa kūlou a me nā ikaika transverse, ʻo ka hapa nui o ia mau kaola. ʻO ke ʻano o ka ʻāpana maʻamau o kēia lālā he I-like. Aia pū kekahi groove, trapezoid a me Z-shape ke liʻiliʻi ka ikaika. Ke nui ka ikaika, hiki ke hoʻohana ʻia ke ʻano pahu. Pono e hoʻomaopopoʻia i ka heluʻana i ka ikaika o ia mau lālā,ʻaʻole wale ka ikaika kulou, akā, e heluʻia ka ikaika a me ke kūpaʻa.
3、 Eccentrically hoʻouka lālā
ʻAʻole ʻeha wale nā lālā i hoʻokaumaha ʻia i ka ikaika axial, akā i ka manawa kulou a me ka ikaika shear transverse. Loaʻa i nā lālā eccentrically koʻikoʻi nā ʻano ʻelua o nā ʻano ʻano keʻa a me nā ʻāpana I-like. Ke nui ka ukana, hiki ke hoʻohana ʻia nā lālā tubular a me ka pahu. ʻO nā lālā i hoʻoukaʻia e nā lālā he nui nāʻano pauku, aʻoi aku ka paʻakikī o ka heluʻana ma mua o nā lālā muaʻelua,ʻo ia hoʻi, e helu i ka ikaika, akā e nānā i ka paʻa.
ʻO nā mea nui o nā hale kila kiʻekiʻe he mau kaola a me nā kolamu. ʻIke loa, ʻokoʻa loa nā ʻano ʻāpana o nā kaola a me nā kolamu, a he nui nā ʻano like ʻole. ʻOiai ʻokoʻa nā ʻano o nā ʻāpana, ua like lākou i nā loina hoʻolālā. ʻO ke ʻano ʻāpana keʻa o ka lāʻau i kaupalena ʻia i ke ʻano-I a me ke ʻano pahu. Hiki ke hoʻokaʻawale ʻia ke ʻano o ka ʻāpana kea o ke kolamu i ʻelua ʻāpana, ʻo ka ʻāpana paʻa kekahi, ʻo ia hoʻi ke ʻano I a me ke ʻano keʻa. ʻO ka ʻāpana ʻē aʻe, ʻo ia hoʻi ka tubular a me ke ʻano pahu.
Mai ka manaʻo o ka hanaʻana, i kekahi mau mea,ʻaʻole hiki i nā lālā i hanaʻia i ke kila kila hoʻokahi ke kūpono i nā koi hoʻolālā. No laila, pono e lawe i kahi ʻano ʻē aʻe, ʻo ia hoʻi, ʻano ʻāpana hui. No ka pauku composite, ua kaupalena wale ia i ka pauku welded composite e like me ka hooulu ana i keia manawa. Hiki ke hoʻokaʻawale ʻia nā ʻāpana composite i ʻelua mau ʻāpana, ʻo ka ʻāpana i haku ʻia me ka ʻāpana kila, a ʻo ka ʻāpana ʻē aʻe ka ʻāpana i haku ʻia me ka ʻāpana kila a me ka pā kila a i ʻole i haku ʻia me ka pā kila. I loko o ka hoʻoheheʻe ʻana, ʻo ka ʻāpana composite i haku ʻia me nā papa kila he maʻalahi loa. No nā mea hoʻolālā, he mea maʻalahi loa ke koho ʻana i kēia ʻāpana composite, ʻo ia ke ʻano o waho a i ʻole ke ʻano ʻāpana o ka ʻāpana. ʻO ka hoʻohana nui ʻana o ka ʻenehana welding maʻalahi i nā makahiki i hala iho nei ua hana pū kekahi i nā kūlana maikaʻi no ka nui o nā ʻāpana e hāpai i ke ʻano o ka ʻāpana hui welding.
ʻO mākou ka mea hana nui loa o ka ʻāpana hollow ma Kina. Hana nui mākou i nā mea i hoʻopilikino ʻia:ʻāpana kūwaha yuantai no ka crane, yuantai ERW paipu, paipu yuantai LSAW, yuantai SSAW paipu, yuantai HFW paipu, yuantai seamless paipu.
