He aha ngā rerekētanga i waenganui i ngā I-papa me ngā H-papa?

1. He aha ngā rerekētanga i waenganui I-papa (I-beam) me te H-papa (H-beam)?

(1) Ka taea hoki te wehewehe i tōna āhua. Ko te tapawhā tapawhā o te poutū I he 工, i te wa e rite ana te tapawhā tapawhā o te poutū H ki te reta H.

(2) Nā te iti noa o te I-papa, mataara ki te tiro ki te tapa (flange) o te I-papa he iti, ka paku ake ki te tata ki te papanga (web), nō reira ka taea anake te eke mai i tētahi taha, ko te H-papa he tino paku ake, ā, he ōrite te rahi o ngā tapa, nō reira ka taea te eke mai i ngā taha katoa

(3) Ko te I beam e tino whakawhanui ana ki ngā momo whare katoa, ko te rohe o te whakamahinga o ngā mema kōpiko ki te whenua he iti noa. Ko te H-beam hī nui e whakamahia ana i te tūhononga hīnana whare me te tūhononga pou o te hanganga hīnana, te tautoko whakauru hīnana, me ētahi atu.

(4) Ko te tapa tuarongo o te H-beam hī he ōrite te kaha, e whai wāhi ana te wāhanga pōroki me te wāhanga huinga e 3 ngāwari e huihui ai. Ko ngā I-beam he wāhanga pōroki, i te mea he iti noa ngā tikanga hana, kei te tapa o waho o te tapa tuarongo he āpiti 1:10. Kaua ko ngā I-beam noa, ko ngā H-beam he pōroki ki te takotoranga kotahi o ngā rōpere poutū, Nā te mea he whānui te tapa tuarongo me te kore he āpiti (tapawhā rānei he iti noa), me te tāpiri i te takotoranga kotahi o ngā rōpere poutū hei pōroki i te wā kotahi. Nō reira, he uaua ake te tikanga pōroki me ngā taputapu i te mīhini pōroki noa.

2.me pēhea te kite mēnā he kounga iti ana te hī?

(1)Ko te tāpapa mekameka he māmā ki te whakararo Ki te he tāpapa whakamua, he māmā ki te whakararo, ka ngaro i te takotoranga taketake o te tāpapa. Ko te take matua ko te whakahaere tāpoi e whai tikanga ana i te kaha, he nui te pēhi, ka arai i te whakakeke o te hua, he māmā ki te whakararo.

(2)Ko te āhua o te tāpapa whakamua he māmā ki te raru i runga i te takotoranga Ko te āhua o te tāpapa whakamua he māmā ki te raru i runga i te takotoranga, ko te take matua ko te wear wear i te parirau, nō reira me tirohia tika mō te āheinga o te āhua ina kōwhiringa ana.

(3)Ko te āhua o te tāpapa whakamua he māmā ki te whara

Ko te tikanga, ko te tāpapa kounga iti he māmā ki te whakauru, ko te āhua he māmā ki te whara, nō reira mai i tēnei tirohanga he māmā te whakatau ko te kounga o te tāpapa he pai, he raru rānei.

(4) Ko te tāpapa mekameka he māmā ki te whakakaha

He nui ngā kaihanga taputapu huihuinga he māmā no te nui o te hanganga, kaua ko te hangarau huihuinga kia tūtohu, nō reira ko te āhua o te tōka e hua ana i ngā rāpoka, ā, kāore te kaha o te tōka i te tūtohu, ki te kaua e hoko i te tōka pēnei
