Rebar, e kiia pinepine ana ko tepā rakau, he mea nui te mahi a te rino i roto i te hanganga, e whakarato ana i te kaha kume e hiahiatia ana hei tautoko i ngā hanganga raima. Ko te momo maitai i whiriwhiria mō tētahi kaupapa e whakawhirinaki ana ki tōna kaha me te whakamahinga motuhake, nō reira me mōhio ngā kaihanga me ngā kaihanga ki ēnei āhuatanga.
He maha ngā momo parepare, ia momo i hangaia mō tētahi whakamahinga motuhake. Ko ngā momo tino noa ko:
1. He reera maitai ngawari(Akomanga 40): Ko te kaha whakaputa o tēnei momo he 40,000 psi, ā, he mea whakamahi noa i roto i ngā kaupapa noho pēnei i ngā ara waka me ngā ara hīkoi. Nā tōna ngāwari ki te whakapiko me te hanga, he ngāwari ki te piko me te hanga.
2. Teitei te kaha maitai(Kōeke 60): Ko te kaha whakaputa o tēnei paera maitai he 60,000 psi, ā, he pai mō ngā mahi arumoni me ngā mahi ahumahi, tae atu ki ngā whare teitei me ngā piriti. Mā te whakanui ake i tōna kaha ka taea te whakaiti i te whakamahinga o ngā rauemi me te kore e pā ki te kounga o te hanganga.
3. Paera pania ki te epoxy: He momo epoxy tēnei kua pania hei ātete i te waikura, he mea tino pai mō ngā hanganga e pāngia ana e ngā taiao uaua, pērā i ngā mahi moana, ngā wāhi rānei he nui te haumākū.
4. He reera kowiri tiraE mōhiotia ana te rino kore waikura mō tōna ātete pai ki te waikura, ā, e whakamahia ana i roto i ngā taiao waikura nui pērā i ngā wheketere matū me ngā hanganga takutai moana.
Te taumata kaha me tōna hiranga:
Ko te kaha o te rino te mea nui hei whakatau i tōna kaha ki te pupuri. Ko ngā kaha teitei ake, pērā i te 75, te 80 rānei, ka nui ake te kaha kume, ā, he pai mō ngā mahi taumaha. Ko te whiriwhiri i te kaha ka pā tika ki te hoahoa me te haumaru o te hanganga nā te mea ka pā ki te nui o te kawenga ka taea e ngā rino te tautoko.
Hei whakamutunga, he mea nui te mārama ki ngā momo parepare me ō rātou taumata kaha e rite ana ki te whiriwhiri i te rauemi tika mō tētahi kaupapa hanga. Mā te whakaaro ki ngā tono motuhake me ngā āhuatanga taiao, ka taea e ngā kaihanga te whakarite i te roa o te mahi me te haumaru o ā rātou hanganga.
