Ma ka ʻoihana kūkulu hale,Nā kukuna Hua ʻike ʻia ʻo "ke kuamoʻo o nā hale hāpai ukana"—ʻo kā lākou koho kūpono e hoʻoholo pololei i ka palekana, ka lōʻihi, a me ke kumukūʻai kūpono o nā papahana. Me ka hoʻonui mau ʻana o ke kūkulu ʻana i nā ʻoihana a me nā mākeke hale kiʻekiʻe, pehea e koho ai i nā kaola H e kūlike me nā pono o ka papahana mai kahi ākea o nā huahana ua lilo i mea nui no nā ʻenekinia a me nā hui kūʻai. Aia ma lalo kahi alakaʻi kikoʻī e kālele ana i nā ʻano koʻikoʻi, nā ʻano kūikawā, a me nā hiʻohiʻona noi o nā kaola H e kōkua i nā mea pāʻani ʻoihana e hoʻoholo i nā hoʻoholo ʻepekema.

E hoʻomaka me nā ʻAno Koʻikoʻi: E hopu i nā "Kūlana Kumu" o nā H Beams

Pono ke koho ʻana o nā kaola H e kau mua ʻia ma luna o ʻekolu mau ʻano koʻikoʻi hiki ʻole ke kūkākūkā ʻia, ʻoiai e pili pono ana kēia i ka hiki i ka huahana ke hoʻokō i nā koi hoʻolālā kūkulu.

Papa MeaʻO nā mea maʻamau no nā kaola H he kila kūkulu kalapona (e like meQ235B, Q355B H Beamma nā kūlana Kina, a i ʻoleA36, A572 H Beamma nā kūlana ʻAmelika) a me ke kila ikaika kiʻekiʻe haʻahaʻa-alloy. He kūpono ʻo Q235B/A36 H Beam no ke kūkulu kīwila maʻamau (e laʻa, nā hale noho, nā hale hana liʻiliʻi) ma muli o kona hiki ke hoʻopili maikaʻi ʻia a me ke kumukūʻai haʻahaʻa; ʻO Q355B/A572, me ka ikaika hua kiʻekiʻe (≥355MPa) a me ka ikaika tensile, makemake ʻia no nā papahana hana kaumaha e like me nā alahaka, nā hale hana ākea nui, a me nā ʻōpū hale kiʻekiʻe, no ka mea hiki ke hōʻemi i ka nui o ka ʻāpana cross-sectional o ke kaola a mālama i kahi.

Nā Kikoʻī AnaUa wehewehe ʻia nā kukuna H e ʻekolu mau ana koʻikoʻi: ke kiʻekiʻe (H), ka laulā (B), a me ka mānoanoa o ka pūnaewele (d). No ka laʻana, he kukuna H i kapa ʻia "H300×150×6×8"ʻo ia hoʻi he 300mm ke kiʻekiʻe, 150mm ka laulā, 6mm ka mānoanoa o ka pūnaewele, a 8mm ka mānoanoa o ka flange. Hoʻohana pinepine ʻia nā kaola H liʻiliʻi (H≤200mm) no nā hale lua e like me nā joists papahele a me nā kākoʻo ʻāpana; hoʻopili ʻia nā mea nui waena (200mm

Hana Mīkini: E kālele i nā ʻōkuhi e like me ka ikaika o ka hua, ka ikaika tensile, a me ka paʻakikī o ka hopena. No nā papahana ma nā wahi anuanu (e laʻa, ʻākau o Kina, Kanada), pono nā kukuna H e hala i nā hoʻokolohua hopena haʻahaʻa (e like me -40℃ impact toughness ≥34J) e pale aku i ka haki ʻana o ka brittle i nā kūlana hau; no nā wahi seismic, pono e koho ʻia nā huahana me ka ductility maikaʻi (elongation ≥20%) e hoʻoikaika i ke kūpaʻa ʻana o ka ōlaʻi o ka hale.

E hoʻohana i nā ʻano kū hoʻokahi: E hoʻohālikelike i nā "Pōmaikaʻi Huahana" i nā Pono o ka Papahana

Ke hoʻohālikelike ʻia me nā ʻāpana kila kuʻuna e like meNā kukuna Ia me nā kila kahawai, he mau ʻano kūkulu like ʻole ko nā kaola H e kūpono ai lākou no nā hiʻohiʻona kūkulu kikoʻī—ʻo ka hoʻomaopopo ʻana i kēia mau pono ke kī i ke koho i koho ʻia.

Ka Hana Haʻawe KiʻekiʻeʻOi aku ka maikaʻi o ka hoʻokaʻawale ʻana o ka ʻāpana keʻa H o nā kaola H: ʻoi aku ka maikaʻi o nā flanges mānoanoa (nā ʻāpana ʻaoʻao o luna a me lalo) e halihali i ka hapa nui o ka manawa kūlou, ʻoiai ʻo ka pūnaewele lahilahi (ka ʻāpana waena kū pololei) e kūʻē i ka ikaika shear. ʻAe kēia hoʻolālā i nā kaola H e hoʻokō i ka hiki ke halihali ukana kiʻekiʻe me ka hoʻohana ʻana i ke kila liʻiliʻi—hoʻohālikelike ʻia me nā kaola I o ke kaumaha like, ʻoi aku ka ikaika kūlou o nā kaola H he 15%-20%. ʻO kēia ʻano e kūpono ai lākou no nā papahana e alualu ana i ka mālama kālā a me nā hale māmā, e like me nā hale i hana mua ʻia a me ke kūkulu modular.

Paʻa ikaika a me ka hoʻokomo maʻalahiʻO ka ʻāpana keʻa H symmetric e hōʻemi i ka deformation torsional i ka wā o ke kūkulu ʻana, e hoʻolilo ana i nā kaola H i ʻoi aku ka paʻa ke hoʻohana ʻia ma ke ʻano he mau kaola amo nui. Eia kekahi, maʻalahi ka hoʻopili ʻana o kā lākou mau flanges pālahalaha me nā ʻāpana ʻē aʻe (e laʻa me nā bolts, nā welds) me ka ʻole o ka hana paʻakikī—hoʻemi kēia i ka manawa kūkulu ma kahi e 30% i hoʻohālikelike ʻia me nā ʻāpana kila maʻamau ʻole, he mea nui ia no nā papahana wikiwiki e like me nā hale kalepa a me nā ʻōnaehana pilikia.

Kū'ē Maika'i i ka Palaho a me ke Ahi (me ka Lapa'au)ʻO nā kaola H i hana ʻole ʻia he maʻalahi i ka popo, akā ma hope o nā hana ʻili e like me ke galvanizing hot-dip a i ʻole ka uhi epoxy, hiki iā lākou ke pale aku i ka popo i nā wahi pulu a i ʻole ke kahakai (e like me nā kahua kai, nā alanui kahakai). No nā hiʻohiʻona wela kiʻekiʻe e like me nā hale hana ʻoihana me nā umu, hiki i nā kaola H pale ahi (i uhi ʻia me ka pena intumescent fire-retardant) ke mālama i ka hiki ke lawe i ka ukana no 120 mau minuke inā he ahi, e hoʻokō ana i nā kūlana palekana ahi paʻa.

Nā Hiʻohiʻona Noi Pahuhopu: Ke Koho Kūpono

He ʻokoʻa nā koi o nā papahana kūkulu like ʻole no nā kukuna H. Ma ka hoʻohālikelike ʻana i nā waiwai huahana me nā koi o ke kahua hiki ke hoʻonui ʻia ko lākou waiwai. Eia nā hiʻohiʻona noi maʻamau ʻekolu a me nā hui pū ʻana i ʻōlelo ʻia.

Nā Hale Noho a me nā Hale Kalepa KiʻekiʻeNo nā hale me 10-30 papahele, ua ʻōlelo ʻia nā kaola H-waena i hana ʻia mai ke kila Q355B (H250×125×6×9 a i H350×175×7×11). Kākoʻo ko lākou ikaika kiʻekiʻe i ke kaumaha o nā papahele he nui, ʻoiai ʻo ko lākou nui liʻiliʻi e mālama i kahi no ka hoʻolālā kūloko.

Nā Alahaka a me nā Hale Hana LōʻihiPono nā alahaka lōʻihi (nā ʻāpana ≥50 mika) a i ʻole nā kaupaku o ke kahua pāʻani i nā kukuna H nui a paʻa kiʻekiʻe (H400×200×8×13 a ʻoi aku paha).

Nā Hale Hana ʻOihana a me nā Hale WaihonaPono nā hale hana kaumaha (e like me nā hale hana kaʻa) a me nā hale kūʻai nui i nā H-beams i hiki ke kākoʻo i ke kaumaha o nā lako a i ʻole ke kau ʻana i nā ukana.

Mea Hoʻolako Kūkulu Kila Hilinaʻi-Royal Group

ʻO ka Pūʻulu Aliʻi kahiHale hana kukuna H KinaMa Royal Group, hiki iā ʻoe ke loaʻa i kahi laulā piha o nā huahana kūkulu kila, me nā kaola H, nā kaola I, nā kahawai C, nā kahawai U, nā pā pālahalaha, a me nā kihi. Hāʻawi mākou i nā palapala hōʻoia honua, ka maikaʻi i hōʻoia ʻia, a me nā kumukūʻai hoʻokūkū, mai kā mākou hale hana Kina.
