Te taumaha kohatu, te rōrahi, te utu waka｜ Tikanga tātai:
1. Me pehea te tatau i te taumaha o te mapere
I te nuinga o te wa ko te taumaha o te mapere he 2.5 te taumaha (tara) = mita pūtoru kua whakareatia ki te taumahatanga motuhake
Tika: Tangohia he kowhatu tapawha 10 cm hei ine i te taumahatanga na koe
2. Kohatu taumaha te tatau me te utu kawe waka
Kia mohio tatou i te tuatahi (waa) Kohatu rōrahi, e kiia ana ko te mataono, = te roa * te whanui * te teitei o te waahanga kohatu, ka kiia hoki ko te kiato.
He 2.6-2.9 tone mo ia putorino te kiato, te taumaha motuhake ranei o te mapere, a, ko te kiato, te taumaha motuhake ranei o te mapere he 2.5 tone mo ia putorino.
Tātaihia te taumaha kōhatu: rōrahi kōhatu, pūtoru rānei * kiato, tino taumaha ranei, ara: te roa * te whanui * te matotoru * te taumaha motuhake = te taumaha kohatu, ki te hiahia koe ki te mohio ki te utu o ia kohatu (mai i te puna o te puna – te waahi o te whakamahi).
Ko te tikanga tatau:
Te roa * te whanui * te teitei * te wahanga * tone / utu = utu mo ia kohatu.
3. Te tatau i te rōrahi kōhatu, te matotoru me te taumaha
(1) Ko te tatauranga hua anake:
1 taranata = 303×303㎜;
1 ping = 36 ping;1 mita tapawha (㎡) = 10.89 ping = 0.3025 ping
Te tātaitanga taranata: roa (mita) × whanui (mita) × 10.89 = taranata
Hei tauira:
Ko te roa o te 3.24 mita me te whanui o te 5.62 mita, ka tatauhia tana hua taranata → 3.24 × 5.62 × 10.89 = 198.294 taranata = 5.508 ping
(2) Tātaitanga mātotoru:
1. Kua tatauhia ki te henimita (㎝): 1 henimita (㎝) = 10 mm (㎜) = 0.01 mita (m)
(1) Te matotoru noa o te kirikiri: 15mm, 19mm, 25mm, 30mm, 50mm
(2) Te matotoru o te mapere: 20mm, 30mm, 40mm
(3) Te matotoru noa o te kohatu Roma me te kohatu kawemai: 12mm, 19mm
2. Kua tatauhia ki nga tohu:
1 ira = 1/8 inihi = 3.2mm (e mohiotia ana ko 3mm)
4 tohu = 4/8 inihi = 12.8mm (e mohiotia ana ko 12mm)
5 tohu = 5/8 inihi = 16㎜ (e mohiotia ana ko 15㎜)
6 tohu = 6/8 inihi = 19.2mm (e mohiotia ana ko 19mm)
(3) Tatau taumaha:
1. Maariki me te mapere: 5 piro = 4.5㎏;6 tohu = 5㎏;3㎝ = 7.5㎏ 2.
Kohatu Roma: 4 tohu = 2.8㎏;6 tohu = 4.4㎏
4. Kohatu pou, kohatu ahua motuhake Ko te pou kohatu Ko te pou kohatu he tino whanui, he rereke te ahua, kaore he tauira hei whakahua tika.
Ko te tikanga utu wae = utu + hua = utu rawa + utu tukatuka + hua kerekere
(1).Ko te utu o nga rauemi he ngawari ki te tatau, he rereke te utu o te tukatuka na te rereke o te uaua o te tukatuka i te ahua o te rango kohatu, nga momo rauemi e whakamahia ana, me nga taputapu, te kaha ki te tukatuka, me nga tohungatanga o ia wheketere, na reira karekau he huarahi ki te tatau tika..
(2).Mo etahi momo kowhatu maamaa me te ngawari, he ngawari te tatau i runga i te mata.Kia tupato ki te rahi me te tae e hiahiatia ana e nga kaihoko.Ina hoki, he ahua nui te roa o nga poroporo kohatu, na reira he uaua ki te kimi poraka e rite ana ki te rahi, na reira kare e nui te utu.Kaore i te whakaritea kia rite ki te utu pereti tikanga me te utu poraka.Engari kia rite ki te rahinga motuhake, he maha ka whakamahia i muri mai.
(3).Na reira, ko te tikanga tika kua mahia e koe te tukatuka ka taea anake te tatau i muri i te wa roa o te whakaemi wheako.Ko te tikanga, ka whakamahia e nga kaiako mohio te tauira tikanga hei tatau.Tauira: I ta matou kamupene etahi pou he tino uaua ki te whakahaere i mua, a ko te wheketere tukatuka i whakatauhia he utu i runga i nga wheako o mua.Kua mahia e tenei wheketere tukatuka etahi ahua motuhake me nga pou mo te neke atu i te tekau tau.Heoi, na te mea he uaua ake te mahi hanga i te mea i whakaarohia, kua piki ake te utu ma te 50% (te wheketere ake i kii), engari na te pohehe o te wheketere, ka noho tonu te utu ki te utu taketake.Ki te kore e whakatauhia e to matou kamupene, ka mutu, ka ngaro.
(4).Mena he kamupene hokohoko koe, he pai ake kia kaua e whakahua mo nga kohatu ahua motuhake penei i nga pou kowhatu, ina koa ko nga mea uaua ki te whakahaere, he ngawari ranei te he i te whakatau tata.He pai ake te whakahua i te haumarutanga i runga i te utu wheketere.
