He aha ngā rerekētanga i waenga i ngā hihi-I me ngā hihi-H?

1. He aha ngā rerekētanga i waenga i te hihi-I me te hihi-H?

（1） Ka taea hoki te wehewehe mā tōna āhua. Ko te wāhanga whakawhiti o te hihi-I ko “工”, ko te wāhanga whakawhiti o te hihi-H he rite ki te reta “H”.

（2） Nā te matotoru iti o te maitai kurupae-I, me āta tirotiro te flange o te maitai kurupae-I, he matotoru ake te tata ki te tukutuku, nō reira ka taea anake te tu atu i te kaha mai i te taha kotahi, he nui ake te matotoru o te kurupae-H, ā, he ōrite te matotoru o te flange, nō reira ka taea te tu atu i te kaha i ngā taha rerekē.

（3） He pai te kurupae I mō ngā momo whare katoa, he iti noa te whānuitanga o ngā wāhanga piko i roto i te papa. Ka whakamahia te maitai kurupae-H i roto i ngā hanganga maitai o ngā whare ahumahi me ngā whare ā-iwi, ngā kurupae, ngā wāhanga pou, ngā tautoko hanganga maitai ahumahi, me ētahi atu.

（4） He rite te matotoru o te flange maitai H-beam, ko te wāhanga hurihuri me te wāhanga whakakotahi he mea hanga mai i ngā pereti e toru kua whakapirihia. Ko ngā I-beam he wāhanga hurihuri, nā te ngoikore o te hangarau whakaputa, ko te taha o roto o te flange he pari 1:10. Kāore i rite ki ngā I-beam noa, ka hurihia ngā H-beam me te huinga kotahi o ngā roera whakapae. Nā te mea he whānui te flange, ā, kāore he piko (he iti rawa rānei), me tāpiri he huinga roera poutū ki te hurihuri i te wā kotahi. Nō reira, he uaua ake te tukanga hurihuri me ngā taputapu i te mira hurihuri noa.

2. Me pēhea te kite mēnā he maitai iti iho?

（1）He ngāwari te whakapiko i te maitai rūpahu, iti iho te kounga. Mēnā he maitai iti iho te kounga, he ngāwari te piko, ka ngaro te āhua taketake o te maitai. Ko te take matua o tēnei, he whai noa ngā kaihanga i te whai huatanga teitei, he nui te pēhanga, ka heke te kaha o te hua, ka ngāwari te piko.

(2) He maha ngā wā ka puta he āhua kore ōrite o te mata o te maitai ngoikore. He maha ngā wā ka puta he āhua kore ōrite o te mata o te maitai ngoikore, ko te nuinga nā te kakahu o te awaawa i puta ai, nō reira me āta tirotiro mēnā he hapa tēnei i te wā e whiriwhiri ana.

（3）Ka ngawari te pakaru o te mata o te maitai ngoikore

I te nuinga o te wā, ka ngāwari te poke o te maitai kounga iti, ka ngāwari hoki te haehae i te mata, nō reira, mai i tēnei wā, he māmā noa iho te kī he pai, he kino rānei te kounga o te maitai.

（4） He ngāwari te waru i te maitai rūpahu, iti iho te kounga

He māmā noa iho te nuinga o ngā kaihanga taputapu whakaputa, kāore te hangarau whakaputa i te paerewa, nō reira ka puta he pūwero i te mata o te hanga maitai, ā, kāore te kaha o te maitai i te paerewa, ki te kore e hokona tēnei momo maitai.
