He mea nui te mīhini hurihuri mō te kawe, ko te nuinga o te kawe he mea pupuri ā-ringa, he mea tōia rānei. I te wā e whiriwhiri ana koe i ngā mīhini hurihuri, me whakawhirinaki koe ki te whakamahinga o ngā taputapu me te whakamahinga o ngā āhuatanga taiao, kia whiriwhiria ai ngā mīhini hurihuri e tika ana.
Tuatahi, ina whiriwhiri koe i ngā wira, me whakaaro koe ki te momo papa e whakamahia ana e koe? He raima, he māpere rānei? He ngohengohe, he mārō rānei te papa? Me nui te tiakitanga mō te papa?
I runga anō i te whakamahinga, ka tūtohu mātou i te nairona, i te polyurethane kaha-teitei rānei (TPU) mō ngā papa raima whānui, me ngā wira rapa, i te polyurethane whakarewa rānei (PU) mō ngā papa māpere o roto, papa rakau rānei.
Mā te whakarerekē i te rauemi o te mata o te wira o ō wira ka taea e koe te whakanui ake i tōna whai huatanga.
Tuarua. He aha te taumaha me te tere o te tono? Ko te tere o tō nekehanga, ko te nui ake o te taumaha e hiahiatia ana e ngā kaihurihuri. Ko te whānui, te whānui me te rauemi o te kaihurihuri ka pā ki te taumaha ka taea e te kaihurihuri te kawe i ngā tere tiketike, i ngā tere iti rānei.
Hei whakatau i te kaha kawenga e hiahiatia ana mō ia mīhini hurihuri i runga i te kāreti, wehea te kawenga kāreti mōrahi mā te maha o ngā mīhini hurihuri. Kātahi ka whakareatia tēnei hua mā te tauwehenga haumaru e whakawhirinaki ana ki ngā āhuatanga tono.
C = Te kaha kawenga e hiahiatia ana mō ngā wira
L = Te kawenga mōrahi o te kāreti
W = Taumaha o te kāreti
n = te maha o ngā wira i whakamahia
SF = Tauwehe Haumaru
Te kawe ā-ringa i roto i te whare = 1.35 (iti iho i te 3 maero ia hāora)
Te kawe ā-ringa ki waho = 1.8 (iti iho i te 3 maero ia hāora)
Te kawe waka hiko o roto = 2 (iti iho i te 3 maero ia hāora)
Te kawe waka hiko o waho = 3 (iti iho i te 3 maero ia hāora)
Ko te āhua māmā ake tēnei o tēnei whārite mō tētahi kāreti paerewa 4-whakarewa me ngā kāreti whānui e rua me ngā kāreti ahunga e rua, me te tohatoha taumaha ōrite i runga i ia wira i raro i ngā āhuatanga kawe ā-ringa o roto:
C = Te kaha kawenga e hiahiatia ana mō ngā wira
L = Te kawenga mōrahi o te taraka
W = Taumaha o te kāreti
Hei tauira, whakaarohia he kāreti 300 pauna me te kawenga 1,800 pauna kei runga. Ko te 2,100 pauna tēnei ka wehea ki te 3. Mō tēnei kawenga, me tautoko/me whakatauranga ia kaitaka mō te 700 pauna, neke atu rānei.
Me arotake anō hoki ētahi atu āhuatanga hei tautuhi i te mīhini hurihuri tika e hiahiatia ana mō te tono, pērā i: te hanganga o te mīhini hurihuri, te pāmahana taiao, te huringa mahi, te rauemi takahanga, me te tere (ka iti ake te kaha kawenga o ngā wira he peera pōro i ngā tere neke atu i te 3 maero ia hāora).
Pērā tonu, ka taea e ā mātou tohunga otinga te matapaki i tō tono kia tika ai te whakamahi i te mīhini huri, nā te mea ehara ngā mīhini huri i te mea he wira noa iho.
Tuatoru, he aha te pāmahana o te taiao e whakamahia ana? Kei roto, kei waho rānei ngā wira e whakamahia ana? I te whakamahinga tūturu, ka pāngia te mahi a te wira e te pāmahana teitei me te pāmahana iti.
Tuawhā, he aha ngā āhuatanga me ngā taiao motuhake e whakamahia ai ō wira? He paru kei roto? He makuku, he matū kino rānei? Ka pā tonu te rā ki ō wira? Ka rere te hiko pateko ki ngā wira, ka kino hoki ngā hua whai hua?
Me whakauru ēnei pātai katoa me ētahi atu ki te tukanga whakatau.
Mena he pātai anō āu mō te kōwhiringa o te mīhini hurihuri, tēnā whakapā mai ki a mātou.
