Hoʻokaʻawale ʻia nā H-beam ma lalo o nā kūlana ʻEulopa e like me ko lākou ʻano cross-sectional, ka nui a me nā waiwai mechanical. I loko o kēia pūʻulu, ʻelua ʻano maʻamau ʻo HEA a me HEB, ʻo kēlā me kēia mea he mau hiʻohiʻona noi kikoʻī. Aia ma lalo kahi wehewehe kikoʻī o kēia mau hiʻohiʻona ʻelua, me ko lākou ʻokoʻa a me ka hoʻohana ʻana.
HEAmoʻo
ʻO ka moʻo HEA he ʻano hao H-beam me nā ʻāpana liʻiliʻi i kūpono i nā hale kūkulu e pono ai ke kākoʻo kiʻekiʻe. Hoʻohana mau ʻia kēia ʻano kila i nā hale kiʻekiʻe, nā alahaka, nā tunnels, a me nā ʻoihana ʻenehana ʻē aʻe. ʻO ka hoʻolālā ʻana o ka ʻāpana HEA e hōʻike ʻia e kahi kiʻekiʻe o ka ʻāpana kiʻekiʻe a me kahi pūnaewele lahilahi, kahi e hoʻomaikaʻi ai i ka pale ʻana i nā manawa kulou nui.
ʻO ke ʻano ʻāpana keʻa: Hōʻike ke ʻano ʻāpana keʻa o ka moʻo HEA i kahi ʻano H maʻamau, akā me kahi ākea ākea haiki.
Nui ka laulā: He ākea ka ʻaoʻao akā he lahilahi nā pūnaewele, a ʻo ke kiʻekiʻe maʻamau mai 100mm a 1000mm, no ka laʻana, ʻo ka nui o ka ʻāpana o HEA100 ma kahi o 96 × 100 × 5.0 × 8.0mm (kiʻekiʻe × laula × mānoanoa pūnaewele × mānoanoa flange).
Meter kaumaha (kaumaha no ka mika): Ke piʻi aʻe ka helu kumu hoʻohālike, piʻi pū ka paona mika. No ka laʻana, he mika ke kaumaha o ka HEA100 ma kahi o 16.7 KG, aʻo ka HEA1000 he ʻoi aku ka nui o ka mika kaumaha.
Ka ikaika: ʻO ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa, akā haʻahaʻa haʻahaʻa ka haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka moʻo HEB.
Paʻa: ʻO nā flanges ʻano lahilahi a me nā pūnaewele ʻoi aku ka nāwaliwali ma ke ʻano o ka paʻa i ka wā i hoʻokau ʻia i ke kaomi a me nā manawa kulou, ʻoiai hiki iā lākou ke hoʻokō i nā koi hoʻolālā he nui i loko o kahi pae hoʻolālā kūpono.
ʻO ke kūpaʻa torsional: ʻO ke kūpaʻa torsional he mea liʻiliʻi a kūpono i nā hale i koi ʻole i nā ikaika torsional kiʻekiʻe.
Nā noi: Ma muli o kona kiʻekiʻe o ka pauku a me ka ikaika kulou maikaʻi, hoʻohana pinepine ʻia nā ʻāpana HEA i kahi koʻikoʻi o ke ākea, e like me ke ʻano kumu o nā hale kiʻekiʻe.
ʻO ke kumukūʻai hana: He liʻiliʻi ka mea i hoʻohana ʻia, maʻalahi ke kaʻina hana, a ʻoi aku ka haʻahaʻa o nā koi no nā lako hana, no laila he haʻahaʻa ke kumu kūʻai.
Kumukūʻai Makeke: Ma ka mākeke, no ka lōʻihi like a me ka nui, ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka moʻo HEB, aia kekahi mau kumukūʻai kūpono a kūpono i nā papahana koʻikoʻi.
HEBmoʻo
ʻO ka moʻo HEB, ma ka ʻaoʻao ʻē aʻe, he H-beam ākea ākea, ʻoi aku ka kiʻekiʻe o ka lawe ʻana i ka ukana ma mua o HEA. He kūpono loa kēia ʻano kila no nā hale kūkulu hale nui, nā alahaka, nā hale kiaʻi, a me nā mea hana ʻē aʻe kahi e pono ai ka lawe ʻana i nā ukana nui.
Māhele Māhele: ʻOiai ke hōʻike nei ʻo HEB i ke ʻano H like, ʻoi aku ka laulā o ka laula ma mua o HEA, e hāʻawi ana i ka paʻa a me ka hiki ke amo.
Nui ka laulā: ʻoi aku ka nui o ka flange a ʻoi aku ka mānoanoa o ka pūnaewele, ʻo ke kiʻekiʻe mai ka 100mm a 1000mm, e like me ka kikoʻī o HEB100 ma kahi o 100 × 100 × 6 × 10mm, no ka nui o ka flange, ʻoi aku ka nui o ka ʻāpana ʻāpana a me ke kaumaha mika o HEB ma lalo o ka helu like.
Meter kaumaha: No ka laʻana, ʻo ke kaumaha o ka mika o HEB100 ma kahi o 20.4KG, ʻo ia ka piʻi ʻana i ka 16.7KG o HEA100; ʻike ʻia kēia ʻokoʻa i ka piʻi ʻana o ka helu kumu hoʻohālike.
Ka ikaika: Ma muli o ka lauwili ākea a me ka pūnaewele ʻoi aku ka mānoanoa, ʻoi aku ka kiʻekiʻe o ka tensile ikaika, ʻoi aku ka hopena a me ka ikaika shear, a hiki iā ia ke pale aku i ka ʻoi aku ka nui o ka piʻi ʻana, ka ʻili a me ka torque.
Paʻa: Ke hoʻokau ʻia i nā ukana nui a me nā ikaika o waho, hōʻike ia i ke kūpaʻa ʻoi aku ka maikaʻi a ʻoi aku ka liʻiliʻi o ka deformation a me ka paʻa ʻole.
ʻO ka hana torsional: ʻoi aku ka nui o ka flange a me ka pūnaewele mānoanoa i ʻoi aku ka maikaʻi ma ka hana torsional, a hiki iā ia ke pale pono i ka ikaika torsional e hiki mai ana i ka wā o ka hoʻohana ʻana i ka hale.
Nā noi: Ma muli o kāna mau ʻāpana ākea a me ka nui o ka ʻāpana ʻāpana, kūpono nā ʻāpana HEB no nā noi kahi e koi ʻia ai ke kākoʻo a me ke kūpaʻa hou, e like me ke ʻano o nā mīkini kaumaha a i ʻole ke kūkulu ʻana i nā alahaka ākea nui.
ʻO nā kumukūʻai hana: ʻoi aku ka nui o nā mea maka, a ʻo ke kaʻina hana e pono ai nā mea hana a me nā kaʻina hana, e like me ke kaomi nui aʻe a me ka mana pololei i ka wā o ka ʻōwili ʻana, e hopena i nā kumukūʻai kiʻekiʻe.
Kumukūʻai makeke: ʻO nā kumu kūʻai kiʻekiʻe ka hopena i ke kumu kūʻai makeke kiʻekiʻe, akā i nā papahana me nā koi hana kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai / hana.
Hoʻohālikelike piha
Ke koho ma waenaHea / Heb, aia ke kī i nā pono o ka papahana kiko'ī. Inā makemake ka papahana i nā mea me ke kūpale kūlou maikaʻi a ʻaʻole i hoʻopilikia nui ʻia e nā kaohi ākea, a laila ʻoi aku ka maikaʻi o HEA. ʻO ka mea ʻē aʻe, inā ʻo ka manaʻo nui o ka papahana e hāʻawi i ka hiki ke hoʻopaʻa paʻa ikaika a me ke kūpaʻa, ʻoi aku ma lalo o nā haʻahaʻa koʻikoʻi, ʻoi aku ka kūpono o ka HEB.
He mea nui nō hoʻi e hoʻomaopopo he ʻokoʻa liʻiliʻi liʻiliʻi ma waena o nā profile HEA a me HEB i hana ʻia e nā mea hana like ʻole, no laila he mea nui e nānā pālua i nā ʻāpana kūpono e hōʻoia i ka hoʻokō ʻana i nā koi hoʻolālā i ka wā o ke kaʻina kūʻai maoli a hoʻohana. I ka manawa like, ʻo kēlā me kēia ʻano i koho ʻia, pono e hōʻoia i ka hoʻokō ʻana o ke kila i koho ʻia me nā ʻōlelo o nā kūlana ʻEulopa kūpono e like me EN 10034 a ua hala i ka palapala hōʻoia kūpono. Ke kōkua nei kēia mau hana e hōʻoia i ka palekana a me ka hilinaʻi o ka hale hope.
