Hanganga Rino Āhua-H EN H Kurupae
H-hikuHe whānuitia te whakamahinga o te maitai, ā, ko te nuinga o ēnei he: ngā momo hanganga whare ā-iwi me ngā hanganga ahumahi; ngā momo whare ahumahi whānui me ngā whare teitei hou, inā koa i ngā wāhi e maha ana ngā mahi rū whenua me ngā āhuatanga mahi pāmahana teitei; e hiahiatia ana ngā piriti nui me te kaha kawe nui, te pumau whakawhiti-wāhanga pai me te whānui nui; ngā taputapu taumaha; te huarahi tere; te anga kaipuke; te tautoko maina; te maimoatanga turanga me te hangarau tāpae; ngā momo wāhanga mīhini.
TE TUKANGA HANGA HUA
Ko te flange oH-hikuHe whakarara, he tata whakarara rānei te āhua o roto, o waho hoki, ā, kei te koki matau te pito o te flange, nō reira i tapaina ai ko te flange I-maitai whakarara. He iti ake te matotoru o te tukutuku o te maitai āhua-H i te matotoru o ngā kurupae-I noa me te teitei ōrite o te tukutuku, ā, he nui ake te whānui o te flange i te matotoru o ngā kurupae-I noa me te teitei ōrite o te tukutuku, nō reira i tapaina ai hoki ko ngā kurupae-I whānui-taha. E whakatauhia ana e te āhua, ko te modulus wāhanga, te nekehanga o te inertia me te kaha e rite ana o te kurupae-H he mārama ake he pai ake i te kurupae-I noa me te taumaha kotahi. Ka whakamahia i roto i ngā whakaritenga rerekē o te hanganga whakarewa, ahakoa kei raro i te taipana piko, te kawenga pēhanga, te kawenga rerekē e whakaatu ana i tana mahi pai ake, ka taea te whakapai ake i te kaha kawe i te maitai-I noa, ka penapena i te whakarewa 10% ~ 40%. He whānui te flange o te maitai āhua-H, he angiangi te tukutuku, he maha ngā whakaritenga, ā, he ngāwari te whakamahinga, ka taea te penapena i te 15% ki te 20% o te whakarewa i roto i ngā hanganga whariki rerekē. Nā te mea he whakarara te taha o roto, o waho hoki o tōna flange, ā, kei te koki matau te pito o te taha, he ngāwari te huihui me te whakakotahi ki ngā wāhanga rerekē, ka taea te penapena i te 25% o te mahi whakarewa me te whakakī, ā, ka taea te whakatere tere i te tere hanga o te kaupapa me te whakapoto i te wā hanga.

NGĀ ĀHUATANGA
He maha ngā whakaritenga o te huaH-hiku, ā, ko ngā tikanga whakarōpūtanga e whai ake nei.(1) E ai ki te whānui o te flange o te hua, ka wehea ki te flange whānui, te flange waenga me te flange whaiti H-kurupae. Ko te whānui o te flange B o te flange whānui me te flange waenga H-kurupae he nui ake, he ōrite rānei ki te teitei tukutuku H. Ko te whānui o te flange B o te maitai āhua-H whaiti he rite ki te haurua o te teitei H o te pereti tukutuku.(2) E ai ki te whakamahinga o te hua, ka wehea ki te kurupae maitai momo-H, te pou maitai momo-H, te puranga maitai momo-H me te kurupae maitai momo-H me te flange matotoru rawa. I ētahi wā ka whakaurua hoki te maitai awa waewae whakarara me te maitai kurupae-T flange whakarara ki te whānuitanga o ngā kurupae-H. I te nuinga o te wā, ka whakamahia te maitai kurupae-H flange whaiti hei kurupae, ā, ka whakamahia te maitai kurupae-H flange whānui hei pou. Nō reira, e mōhiotia ana hoki ko te maitai kurupae-H kurupae me te maitai kurupae-H pou. (3) E ai ki te tikanga whakaputa, ka wehea ki te maitai kurupae-H whakarewa me te maitai kurupae-H hurihuri. (4) E ai ki ngā whakaritenga rahi, ka wehea ngā maitai āhua-H nui, reo-waenga me te iti. Ko ngā hua he teitei tukutuku H neke atu i te 700mm ka kiia he nui, ko ngā 300 ~ 700mm ka kiia he reo-waenga, ā, ko ngā mea iti iho i te 300mm ka kiia he iti. I te mutunga o te tau 1990, ko te teitei tukutuku kurupae-H nui rawa atu o te ao he 1200mm, ko te whānui o te flanges he 530mm.
TE TIROHANGA O NGĀ HUA
Ko ngā whakaritenga mō te tirotiro maitai āhua-H ko ēnei ngā āhuatanga matua:
Te kounga āhua: Me tutuki te kounga āhua o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana. Me maeneene, me papatahi te mata, kāore he pakaru, he karawarawa, he waikura me ētahi atu hapa e kitea ana.
Ngā ine āhuahanga: Me tutuki te roa, te whānui, te teitei, te matotoru o te tukutuku, te matotoru o te flange me ētahi atu ine o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana.
Piko: Me tutuki te piko o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana. Ka taea te kite mā te ine mēnā he whakarara ngā papa i ngā pito e rua o te maitai āhua-H, mā te whakamahi rānei i te mita piko.
Tahuri: Me tutuki te tahuri o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana. Ka taea te kite mā te ine mēnā he poutū te taha o te maitai āhua-H, mā te mita tahuri rānei.
Te rerekētanga taumaha: Me tutuki te taumaha o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana. Ka taea te kite i ngā rerekētanga taumaha mā te pauna.
Te hanganga matū: Mena me whakarewa, me tukatuka rānei te maitai āhua-H, me tutuki te hanganga matū ki ngā paerewa me ngā whakaritenga tono e tika ana.
Ngā āhuatanga hangarau: Me tutuki ngā āhuatanga hangarau o te maitai āhua-H ki ngā paerewa me ngā whakaritenga raupapa e tika ana, tae atu ki te kaha kume, te pūwāhi tuku, te roa me ētahi atu tohu.
Whakamātautau kore-whakangaro: Mena me whakamātautau kore-whakangaro te maitai āhua-H, me whakamātautau kia rite ki ngā paerewa me ngā whakaritenga tono e tika ana kia pai ai tōna kounga o roto.
Te takai me te tohu: Me tutuki te takai me te tohu o te maitai āhua-H ki ngā paerewa me ngā whakaritenga tono e tika ana hei whakahaere i te kawe me te rokiroki.
I te poto, me āta whakaarohia ngā whakaritenga o runga ake nei ina tirotirohia te maitai āhua-H kia mōhio ai kei te tutuki tōna kounga i ngā paerewa e tika ana me ngā whakaritenga tono, ā, kia whakaratohia hoki ki ngā kaiwhakamahi ngā hua maitai āhua-H pai rawa atu.
Tono
NoaH-hikuKo ngā rauemi maitai ko te Q235B, SM490, SS400, Q345 me te Q345B. He rerekē te hanganga matū me ngā āhuatanga hangarau o ēnei rauemi, nō reira, i te wā e whiriwhiri ana i te whakamahinga o te H-beam, me whiriwhiri te rauemi e tika ana kia rite ki te āhuatanga motuhake.
TE TĀKAI ME TE TUKU
Te tākai me te tiakitanga:
He mea nui te takai hei tiaki i te kounga o te ASTM A36H-hikute maitai i te wā e kawe ana, e penapena ana hoki. Me herea pai te rauemi, me te whakamahi i ngā whitiki kaha, i ngā here rānei hei ārai i te nekeneke me te kino pea. Hei tāpiri, me mahi ngā mahi hei tiaki i te maitai mai i te makuku, te puehu, me ētahi atu āhuatanga taiao. Mā te takai i ngā paihere ki ngā rauemi ātete-huarere, pērā i te kirihou, te papanga ātete-wai rānei, ka āwhina i te tiaki i te waikura me te waikura.
