Mō ngā tirohanga ataahua me te haumaru pumau, ko te karāhe whakamaroke te paerewa tino tika mō ngā taiapa puna kaukau hou. Engari he aha te momo me te matotoru e pai ana? Anei te wehewehenga:
Karāhe Haumaru Whakamarumaru Katoa:
Momo: Ko te karāhe anake e tika ana mō te taiapa kaukau. Ka tukatukahia mā te whakamahana nui me te whakamatao tere, ka 5-6 ngā wā e kaha ake ana i te karāhe noa.
Painga Matua: Ka pakaru ki ngā wahi iti, kāore i te kino, ka whakaiti i te tūponotanga whara mēnā ka pāngia. Kāore e taea te whiriwhiri i ngā ture haumaru.
Te Mea Matua: Te Matotoru o te Karāhe
Matotoru Paerewa: 12mm (tata ki te 1/2 inihi) te paerewa ahumahi me te whakaritenga iti rawa i te nuinga o ngā rohe mō ngā hoahoa kore-anga, kore-anga rānei.
He aha i 12mm ai? He tino pakari te hanganga, he ātete ki te hau, me te kaha pānga e tika ana mō te ārai haumaru. Ko te karāhe angiangi (hei tauira, 10mm) kāore i te tūtohutia, kāore hoki i te tutuki i ngā whakaritenga mō te taiapa haumaru kaukau nā te mea ka piko pea, ka ngoikore rānei.
Teitei me te Whānuitanga: Mō ngā panera teitei ake (neke atu i te 1.2m/4 putu) me ngā whānuitanga roa ake kāore he tautoko, ka taea e ngā kaihangarau te tohu i te karāhe whakakikorua/whakamaroke 15mm, matotoru ake rānei hei whakapai ake i te pumau.
Kōwhiringa: Karāhe Whakamarumaru Kua Whakakikoruatia:
Hanganga: E rua ngā paparanga karāhe kua whakapakeketia kua herea ki tētahi paparanga pakari (pēnei i te PVB).
Painga: He nui ake te ātete ki te pānga me te haumarutanga. Mēnā ka pakaru, ka pupuri te paparanga i ngā kongakonga karāhe ki tōna tūranga, hei ārai tuarua. He pai mō ngā rohe hau nui, mō ngā whakaurunga papai rānei.
Taunakitanga: Me whakamahi tonu i te karāhe kua whakamanahia, he 12mm te matotoru, hei tūāpapa mō te taiapa kaukau. Me whakarite kia tutuki i ngā ture haumaru kaukau ā-rohe (hei tauira, AS/NZS 1926, ASTM F1346) ā, kua tāutahia e ngā tohunga whaimana e whakamahi ana i ngā taputapu maitai kore waikura kounga moana hei pupuri i te roa o te wā me te ātete ki te waikura. Whakatairangahia te haumaru kua whakamanahia i te whakaiti i te utu mō te matotoru.
