I ka ʻoihana kūkulu hale,H kaolaʻike ʻia ʻo "ka iwi kuamoʻo o nā hale halihali ukana" - ʻo kā lākou koho kūpono e hoʻoholo pololei i ka palekana, ka lōʻihi, a me ka uku-pono 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 kukui H e kūpono i nā pono o ka papahana mai kahi ākea o nā huahana i lilo i kumu nui no nā ʻenekinia a me nā hui kūʻai. Aia ma lalo kahi alakaʻi kikoʻī e kālele ana i nā ʻano kī, nā hiʻohiʻona kūʻokoʻa, a me nā hiʻohiʻona noiʻi o H beams e kōkua i nā mea pāʻani ʻoihana e hana i nā hoʻoholo ʻepekema.

E hoʻomaka me nā ʻano kumu: hopu i nā "kumu kumu" o nā H Beams

Pono e koho mua ʻia ke koho ʻana i nā kukuna H ma luna o ʻekolu mau hiʻohiʻona koʻikoʻi hiki ʻole ke kūʻai ʻia, no ka mea e pili pono ana kēia mau mea inā hiki i ka huahana ke hoʻokō i nā koi hoʻolālā hoʻolālā.

Papa Mea： ʻO nā mea maʻamau no nā kaola H he kila kila (e like meQ235B, Q355B H Kaolama nā kūlana Kina, a i ʻoleA36, A572 H Kaolai nā kūlana ʻAmelika) a me ke kila ikaika kiʻekiʻe. Q235B/A36 H He kūpono ke kukui no ka hana kīwila maʻamau (e laʻa, nā hale noho, nā hale hana liʻiliʻi) ma muli o kona maikaʻi weldability a me ke kumu kūʻai haʻahaʻa; ʻO Q355B / A572, me ka ikaika hua kiʻekiʻe (≥355MPa) a me ka ikaika tensile, makemake ʻia no nā hana koʻikoʻi e like me nā alahaka, nā hale hana nui, a me nā cores hale kiʻekiʻe, no ka mea hiki iā ia ke hōʻemi i ka nui o ke keʻa o ka lāʻau a mālama i kahi ākea.

Nā ʻōlelo kikoʻī: Ua wehewehe ʻia nā kukui H e nā ana kī ʻekolu: ke kiʻekiʻe (H), ka laula (B), a me ka mānoanoa pūnaewele (d). No ka laʻana, he kukuna H i kapa ʻia "H300×150×6×8"ʻo ia hoʻi, he 300mm kona kiʻekiʻe, 150mm ka laulā, 6mm ka mānoanoa pūnaewele, a me ka mānoanoa flange o 8mm. Hoʻohana pinepine ʻia nā kukui H liʻiliʻi liʻiliʻi (H≤200mm) no nā hale kiʻekiʻe e like me nā kuʻi papahele a me nā kākoʻo pā; nā hale; he nui ka nui H kaola (H≥400mm) no nā alahaka kiʻekiʻe kiʻekiʻe, nā alahaka lōʻihi, a me nā papa hana ʻoihana.

Hana Mechanical: E noʻonoʻo i nā hōʻailona e like me ka ikaika hoʻohua, ka ikaika tensile, a me ka paʻakikī hopena. No nā papahana ma nā ʻāina anu (e laʻa, ʻo Kina akau, Kanada), pono e hele nā kukui H i nā hoʻokolohua hopena haʻahaʻa haʻahaʻa (e like me ka -40 ℃ paʻakikī hopena ≥34J) i mea e pale ai i ka haki ʻana i nā kūlana maloʻo; no nā ʻāpana seismic, pono e koho ʻia nā huahana me ka ductility maikaʻi (elongation ≥20%) i mea e hoʻoikaika ai i ka pale ʻana i ke olai.

Hoʻohana i nā hiʻohiʻona kūʻokoʻa: E hoʻohālikelike i nā "Pono Hua" i nā pono o ka papahana

Hoʻohālikelike ʻia me nā ʻāpana kila maʻamau e like meI-kuolaa me nā kila awāwa, loaʻa i nā kaola H nā hiʻohiʻona ʻokoʻa i kūpono iā lākou no nā hiʻohiʻona kūkulu kikoʻī - ʻo ka hoʻomaopopo ʻana i kēia mau mea pono ke kī i ke koho ʻia.

Kiekie Haawe-Hawe Pono: Hāʻawi ka ʻaoʻao H-like o nā kaola H me ka noʻonoʻo pono: ʻo nā flanges mānoanoa (nā ʻaoʻao ʻaoʻao o luna a me lalo) e halihali i ka hapa nui o ka manawa piʻo, ʻoiai ʻo ka pūnaewele lahilahi (ka ʻaoʻao waena kūpaʻa) e kūʻē i ka ikaika ʻako. Hiki i kēia hoʻolālā ke hiki i nā kukui H ke hoʻokō i ka hiki ke lawe i ka haʻahaʻa kiʻekiʻe me ka liʻiliʻi o ka hoʻohana ʻana i ke kila—i ka hoʻohālikelike ʻia me nā I-beams o ke kaumaha like, ʻo nā kukui H he 15% -20% kiʻekiʻe ka ikaika kulou. ʻO kēia hiʻohiʻona e kūpono iā lākou no nā papahana e ʻimi ana i ka mālama kālā a me nā hale māmā, e like me nā hale prefabricated a me nā kūkulu modular.

Paʻa Paʻa & Hoʻokomo maʻalahi: ʻO ka ʻāpana H like ʻole e hōʻemi i ka deformation torsional i ka wā o ke kūkulu ʻana, e ʻoi aku ka paʻa o nā kaola H ke hoʻohana ʻia ma ke ʻano he mau kaola amo nui. Eia hou, ua maʻalahi ko lākou mau flanges palahalaha e hoʻohui me nā ʻāpana ʻē aʻe (e laʻa, bolts, welds) me ka ʻole o ka hana paʻakikī-e hōʻemi kēia i ka manawa hana ma ka pūnaewele e 30% ke hoʻohālikelike ʻia me nā ʻāpana kila ʻole, he mea koʻikoʻi no nā papahana wikiwiki e like me nā ʻoihana pāʻoihana a me nā ʻoihana pilikia.

ʻAi maikaʻi a me ke kū ʻana i ke ahi (me ka mālama ʻana): Hiki i nā kaola H i hana ʻole ʻia i ka ʻōpala, akā ma hope o ka mālama ʻana i ka ʻili e like me ka wela wela a i ʻole ka uhi epoxy, hiki iā lākou ke pale aku i ka ʻino ma nā wahi haʻahaʻa a kahakai paha (e laʻa, nā paepae waho, nā alanui kahakai). No nā hiʻohiʻona kiʻekiʻe e like me nā hale hana ʻoihana me nā umu ahi, hiki i nā kukui H (i uhi ʻia me ka pena ahi-retardant intumescent) hiki ke mālama i ka hiki ke halihali i ka ukana no nā minuke 120 i ke ahi, e hālāwai me nā kūlana palekana ahi.

ʻO nā hiʻohiʻona noiʻi pahuhopu: ke koho kūpono

Loaʻa i nā papahana kūkulu ʻokoʻa nā koi like ʻole no nā H-beams. Ma ka hoʻolikelike ʻana i nā waiwai huahana me nā koi pūnaewele hiki ke hoʻonui ʻia ko lākou waiwai. ʻEkolu mau hiʻohiʻona hoʻohana maʻamau a me nā hui pū ʻia.

Nā Hale Noho a me nā Hale Kūʻai Kiʻekiʻe: No nā hale me nā moʻolelo 10-30, ua ʻōlelo ʻia nā kaila H-gauge me 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 kā lākou nui paʻa e mālama i ka wahi no ka hoʻolālā o loko.

Nā Alahaka a me nā ʻĀpana lōʻihi: Pono nā alahaka lōʻihi (spans ≥50 mika) a i ʻole nā hale kahua pāʻani i nā H-beams nui a ʻoi aku ka paʻakikī (H400×200×8×13 a ʻoi aku paha).

Nā mea kanu a me nā hale kūʻai: Pono nā mea kanu kaumaha (e like me nā mea hana kaʻa) a me nā hale kūʻai nui i nā H-beam hiki ke kākoʻo i ke kaumaha o nā lako a i ʻole ka hoʻopaʻa ukana.

ʻO ka hui aliʻi hehale hana kukuna H Kina.Ma ka Royal Group, hiki iā ʻoe ke loaʻa i ka nui o nā huahana hoʻolālā kila, me nā kukui H, I beams, C channels, U channels, flat bars, and angles. Hāʻawi mākou i nā palapala hōʻoia honua, hōʻoia ʻia ka maikaʻi, a me nā kumukūʻai hoʻokūkū, nā mea āpau mai kā mākou hale hana Kina.
