Kōtaha Kurupae H HEA HEB Hanganga Waro Rino Kurupae H
TE TUKANGA HANGA HUA
Koinei te tukanga whānui mō te hanga i te paerewa o waho o te kurupae-H tuwhera:
Te whakarite i ngā rauemi mataKo te rauemi mata mō te hanga i te wāhanga maitai H-beam he mea hanga ki te maitai porowhita. Hei horoi me te whakamahana i te maitai porowhita mō te mahi me te hanga ā muri ake nei.
Te tukanga hurihuri weraKa whakamahanatia te tukatuka hurihuri wera o te pereki maitai. Ina whakamahanatia kia rite ki te āhua hurihuri, ka hurihia te pereki maitai i roto i te mira hurihuri wera, mā te raupapa o ngā roera ka hangaia kia tata ki te āhua H.
Te mahi matao (whiringa kore)Ka taea te mahi matao i te maitai kurupae H-hurihuri wera, pērā i te huri matao, te kume, me ētahi atu hei whakapai ake i te tika me te kounga o te mata o te maitai kurupae H-hurihuri i ētahi mahi.
Te Tapahi me te WhakaotiMe tapahi, me whakaoti hoki ngā Hongere H kua hurihia kia rite ki te rahi me te roa hei whakatutuki i ngā whakaritenga motuhake a te kiritaki i muri i te hurihuri me te mahi matao.
Te maimoatanga mataMa te maimoatanga ma, ā, ārai-waikura o te maitai H, hei whakapūmau i te kounga o te mata me te ātete ki te waikura o ngā hua.
Te tirotiro me te tākaiTirohia te kounga o te maitai H e hangaia ana, tae atu ki te kounga o te āhua, te tika o ngā rahinga, te āhuatanga miihini me ētahi atu. Whai muri i te whakamātautau, ka tākaihia, ka tukuna atu ki te kaihoko.

Whānui te tonoE tika ana te maitai kurupae-H mō ngā momo hanganga whare katoa, te hanganga piriti, te hanga mīhini me ērā atu mea. He whānui te tirohanga whanaketanga.
He kaha teitei, he pumau, he ngāwari hoki te hanga o ngā kurupae-H paerewa whānui o waho. Hei momo rauemi maitai hanganga nui, he whānuitia te whakamahinga i roto i ngā kaupapa maha.
TE TIROHANGA O NGĀ HUA
Hei whakarite i te kounga o te hua, te haumaru, me te tutuki i ngā paerewa o te ao, me tirotirohia ngā H Beams i roto i ngā āhuatanga e whai ake nei:
1. Te Kounga o te Āhua
Me maeneene, me ma, ā, me kore he hapa e kitea ana pērā i ngā kapiti, ngā pakaru, ngā karawarawa, te waikura nui, me ētahi atu hapa mata. Me tutuki te āhua whānui i ngā paerewa e tika ana me ngā whakaritenga a te kiritaki.
2. Te Tika o te Ahu
Ko ngā ine matua tae atu ki te roa, te teitei, te whānui o te flange, te matotoru o te tukutuku, me te matotoru o te flange me tutuki ki ngā paerewa me ngā whakaritenga o te kaupapa kia tika ai te mahi hanganga.
3. Te Tika me te Piko
Me noho tonu te piko o ngā H Beams ki roto i ngā ātete e whakaaetia ana. Ka mahia ngā inenga hei manatoko i te tika me te whakarara o ngā hihi e ai ki ngā paerewa ahumahi.
4. Mana Hurihuri
Me tirotirohia te āhua o te miro kia tika ai te tūnga poutū me te pumau o te hanganga. Tērā pea ka pā te miro nui ki te mahi tāutanga me te kawe kawenga.
5. Manawanui Taumaha
Me tutuki te taumaha tuturu o te kurupae ki ngā paerewa kua tohua me ngā rerekētanga e whakaaetia ana, kia rite ai te kounga o ngā rauemi me ngā tātaitanga hanganga.
6. Tātaritanga Hanganga Matū
Ka whakamātauria ngā huānga matū pēnei i te waro, te konupūmā, te whākōkī, me te whanariki hei manatoko i te tutuki o ngā paerewa rauemi, inā koa mō te whakarewa, te hanga, me ngā tono motuhake.
7. Whakamātautau Āhuatanga Mīhini
Ka whakamātauria te mahi ā-ringa tae atu ki te kaha tuku, te kaha kume, te roa, me te ātete pānga hei whakaū i te tutuki o te kurupae i ngā whakaritenga hanganga e hiahiatia ana.
8. Whakamātautau Kore-Whakangaro (NDT)
Tērā pea ka whakahaerehia te whakamātautau ultrasonic, me ētahi atu tikanga tirotiro kore-whakangaro rānei, hei kimi i ngā hapa o roto, hei whakarite hoki i te pumau me te pono o te hanganga whānui.
9. Te Tirotiro i te Tākai me te Tohu
Me tutuki ngā tohu mō te takai me te hua i ngā paerewa kaweake me te kawe waka, me te tautuhi mārama i te kounga, te rahi, te tau wera, me te rahinga kia taea ai te whai me te tuku haumaru.
Te Whakapūmau Kounga
Mā ngā tikanga tirotiro whānui ka tutuki i ia H Beam ngā paerewa kounga o te ao me ngā whakaritenga a te kiritaki, ka whakaratohia he mahi pono mō ngā tono hanga, hanganga, ahumahi, me te hangarau puta noa i te ao.
TE TONO HUA
He whānuitia te whakamahinga o ngā kurupae H paerewa o waho i roto i te umanga hanga me te mīhini, pērā i ēnei e whai ake nei, engari kāore i te herea ki: Te hangarau hanganga me te hangarau piriti, te miihini, te hanga kaipuke me te whakatū hanganga maitai.
TE TĀKAI ME TE TUKU
Ko te tākai me te tuku o ngā hihi-H noa o waho ka mahia penei:
TākaiKo te tikanga, ka tākaihia te maitai H kia rite ki te tikanga tuku a ngā kaihoko kia kore ai e pakaru te mata. Ko te tākai paerewa he tākai tahanga, he tākai papa rakau, he tākai kirihou me ērā atu. I te wā e tākai ana, kaua te mata o te maitai kurupae H e rakurakuhia, e waikurahia rānei.
Te tapangaTohua ngā mōhiohio mārama mō te hua ki te mata o te takai, pērā i te tauira, te whakatakotoranga, te rahinga, me ētahi atu, kia watea ai mō te tautuhi me te whakahaere.
E utaina anaMe karo hoki i te tukinga me te whakaputanga o te kawenga i te wā e utaina ana te maitai kurupae H me te kawe.
