I te wāhanga o mua, i hipokina e mātou ngā mahi nui o te tango i ngā kete, te tirotiro, te hiki, me te mahi i ngā whakatikatika matapōkere o tō mīhini hanga ngongo ERW hou. Ināianei, ka neke atu tātou ki te tukanga nui o te whakatikatika me te whakarite tika, he mea nui hei whakarite i te hanga ngongo kounga teitei me te mahi whai hua.
Te Mārama ki te Whakatikatika: Te Whāinga o te Whakatikatika Tino Pai
I tēnei horopaki, ko te whakatikatika e pā ana ki te whakatikatika pai o te tukanga hanga porotaka kia pai ai te oma o te ngongo parakore i roto i te mīhini, ā, ka puta he ngongo e tutuki ana i ngā whakaritenga e hiahiatia ana. Mena ka taea e te mīhini te hanga ngongo pēnei, ka taea te kī he angitu ngā "whakatikatika". Ko ngā whakatikatika anō i roto i ngā mahi whakaputa auau he mea pai ake te whakaaro he "whakatikatika raruraru" ina kore ngā mea e mahi ana e ai ki te tumanako.
Ka taea te wehewehe i te whakatikatika o te ngongo whakarewa ki ngā mahi e whai ake nei:
I. Ko te Whakarite te Mea Matua: Te Tirotiro i ngā Rōra me te Aromatawai i te Āhua o te Mīhini
I mua i te ruku ki te tukanga whakatikatika, he mea nui te whakarite tupato:
- Tirotiro Kounga Rōra:Arotahi ki te āhua o te awaawa hanga-pōro. Whakamahia he tauira hei manatoko kei te rite te āhua o ia pōro ki ngā whakaritenga hoahoa. Makahia ngā pōro kāore e tutuki i ngā paerewa. Kia aro hoki ki te whānui o te turanga o te pōro. Mā tēnei ka taea te huri i ngā pōro katoa i roto i te wā kotahi. Me rite te rahi me te āhua o ngā takirua pōro e ōrite ana.
- Tirotiro Āhua o te Mīhini:Me whakarite kei te pai te mahi a te mīhini. Ka taea te whakarāpopoto penei:
- Me ōrite ngā toki whakapae.
- Me tika ngā toki poutū.
- Me pumau te tūnga o te takai.
- Me neke noa, me maeneene hoki ngā wāhanga reti.
- Me ngāwari te mahi i ngā whakatikatika.
Ki te kore te mīhini e tutuki i ēnei whakaritenga, me whakahaere he mahi tiaki hei whakahoki i a ia ki tōna kaha mahi taketake. He mea nui kia whakatikahia tetahi mea e whakaatu ana i ngā whanonga e whai ake nei: kāore e taea te whakarite, kāore i te pumau i muri i te whakaritenga, he tūnga nekeneke rānei.
II. Te Whakarite Tika: Te Pūtake o te Hanga Ngongo Kounga
1. Te Whakaritenga o te Awaawa
Ko te whakatikatika i te awaawa te taahiraa tuatahi o te tukanga whakatikatika.
- Kōwhiria he waea maitai 0.5mm. Whakamahia me ngā roera whāngai o te mīhini hanga ki ngā roera whakatikatika o te mīhini ine hei roa turanga.
- Whakatauhia te pokapū o te rārangi hurihuri. Whakamaua te waea maitai, ka whakatū kia tika, kia pūmau hoki.
- Kia tino teitei ake te teitei o te waea maitai i te diameter o raro o te roera papatahi (2mm, neke atu rānei). Pērā ai, ka kore e pā ki te pewa o te awaawa, ka pā kino ki te ine me te tūnga tika. Ko tēnei waea maitai te rārangi tohutoro mō te whakarārangi awaawa.
2. Te Whakaritenga Roera Whakapae
E rua ngā tikanga mō te whakahāngai i ngā rōra whakapae:
- Tikanga 1: Whakamahia te motuka whakatikatika hei whakaea i ngā rerekētanga matotoru i waenga i ngā roera awaawa. Heoi, ki te kore te tika o te tukatuka wāhanga e tutuki i ngā whakaritenga, ka puta ngāwari ngā hapa tāpiri i muri i te huihuinga, ka pā tika ki te pānga whakahāngai o ngā āhua roera.
- Tikanga 2: Whakamahia he nati raka hei whakatika i te tūranga o ngā roera i runga i te kakau, kia ōrite ai te pokapū o te awaawa o ia roera ki te rārangi pokapū. Ka whakamahia he tauira motuhake hei tirotiro i te tūranga o te pokapū awaawa. I te tirotiro, whakauruhia te tauira ki roto i te awaawa e whakaritea ana, kātahi ka hiki mārire i te pito o runga. Ina taea e te waea maitai te taka mārire ki roto i te awaawa pokapū o te tauira, he tohu tēnei kei te tika te tūranga pokapū o te awaawa, ki te kore, me whakatikatika te nekehanga tuaka. He tikanga whakatikatika ngāwari noa iho tēnei.
Mā te whakarārangi i ngā roera o runga ka whakamahia ngā roera o raro hei tohutoro. Whai muri i te tatau i te tawhiti pokapū i waenga i ngā roera papatahi o runga me raro, whakatikatikahia ngā roera o runga ki te tūranga whakapae. Ko te tātai mō te tatau i te tawhiti pokapū tuaka koia tēnei:
- Tātaitanga Tawhiti Pokapū Tuara o te Awaawa Tuwhera:H = (Dlower + Dupper) ÷ 2 + t – a
- Tātaitanga Tawhiti Pokapū Tuaka o te Awaawa Kati:H = Dlower + 2R – aKei hea:
- Dlower = Te whānui o raro o te roera o raro (mm)
- Dupper = Te whānui o waho o te roera o runga (mm)
- t = Te matotoru o te ngongo kore (mm)
- R = Te pūtoro o te awaawa rahi (mm)
- a = Tauwehenga whakaiti (0.1～0.5)
Ko te nui o te tauwehenga a e whakawhirinaki ana ki te matotoru o te ngongo parakore, te nui o te whakaiti i te diameter o waho o te ngongo, te rahi me ngā whakaritenga, me te āhuatanga tūturu pēnei i te diameter o te rakau me te rerekētanga o te rakau. Heoi, kāore e taea te huri matao i runga i te mīhini hanga. Ka taea te ine me te tirotiro mēnā he tika te nui o te whakaiti i tīpakohia mā te whakamahi i ngā tohu kōhao o te waea fiusi. I te wā e tangohia ana he tauira, tīmatahia te waeine ka whakatuwhera ki te tere puhoi rawa, kātahi ka pikohia te waea fiusi he paku nui ake te diameter i te matotoru o te ngongo parakore kia rite ki te awaawa, ka ata whāngaihia ki roto i te mira hurihuri kia whiwhi ai i te kōhao o te waea fiusi.
I muri i te whakataurite i te roera o runga, ka taea hoki te whakapūmau i te tūranga pokapū tuaka o te roera o runga o te awaawa tuwhera mā te whakamahi i tētahi ine mono tauira-āhua hei tirotiro mēnā he ōrite te āputa i waenga i ngā taha e rua o te awaawa roera o raro me te awaawa roera o runga. Mēnā he ōrite rāua, ka taea te raka i te tūranga tuaka o te roera o runga. Whakamahia te tikanga pā mō ngā awaawa kua kati hei tirotiro mēnā he ōrite ngā awaawa o runga me raro.
3. Te Whakaritenga Roera Poutū
Ka taea te wehewehe i te whakaritenga roera poutū kia toru ngā taahiraa:
- Tuatahi, whakatauhia te āputa whakatuwheratanga o ia rōpū o ngā roera poutū, arā, te tawhiti pokapū tuaka i waenganui i ngā roera poutū e rua;
- Kātahi, kimihia te tūranga pokapū o ia rōpū o ngā roera poutū;
- Hei whakamutunga, whakatikatikahia te teitei o ngā roera poutū.
Me hangai te āputa whakatuwheratanga o te roera poutū ki te whānui o te whakatuwheratanga whakarerekētanga i te wā e hoahoahia ana te āhua roera, kātahi ka whakaitihia kia 5mm pea. Mēnā he nui rawa te whakaiti, ka tere ake te mau o te taha o runga o te āhua roera poutū, ā, ka nui ake te kawenga ki runga i ngā taputapu.
Me whakarite te pokapū o te roera poutū i te wā kotahi me te roera whakapae kia rite ai te tūranga pokapū o ngā roera whakapae me ngā roera poutū ki te rārangi pokapū kotahi. Kia kitea te rārangi pokapū o te awaawa roera poutū, ka taea te whakaheke i te waea maitai ki te tūranga diameter raro o te awaawa roera whakapae, ā, ka taea te tīmata i te teitei o te roera poutū. Me hangai te teitei o te roera poutū ki te teitei o te taha o raro o te awaawa roera poutū e ōrite ana ki te teitei o te waea maitai. Me whakatau te teitei o ngā roera poutū tuatahi i mua i te hanganga kia rite ki ngā tawhā tukanga o te nui o te tapahi mowhiti o te roera o raro.
4. Ētahi atu Whakaritenga Awaawa
Ko te tikanga whakahāngai o ētahi atu āhua hurihuri ka pā ki te mātāpono whakahāngai o ngā roera papatahi me ngā roera poutū. Ko te tikanga anake, ko te tūnga o te diameter o raro o te roera o raro o te roera ārahi me teitei ake i te rārangi tohutoro mā te 0.5~2 mm (i runga i te diameter me te matotoru o te pakitara o te ngongo kua hangaia). Me teitei ake te roera tautoko pūwero i te 0.5mm i te rārangi tohutoro kia pumau ake ai te kaha i te wā e whakahāngai ana i ngā pūwero o waho, ā, kia kore ai e peke te whakahāngai.
