Te Kōwhiringa i ngā Taputapu Wāwahi Taumata mō ngā Kaupapa 2026
Te Pūmau me te Manawaakitanga ki te Āhuarangi o ngā Tiriti Tākarotia Taiao
Te Mahi Painga i ngā Aitenga Āhuarangi: Hukapuka-Whakawhitinga, Kohukohu UV, me te Angaimaha ki te Pouri ā-Matereri
Me mātua āti kaua i te pā ki ngā tikanga hoki, ngā tinihanga e pā ana ki ngā karuwha e wātea ana i waho. Ko ngā wāhi e pā ana ki te ruru, te mātao, te mārie, me ngā aronga e hē ana ko ngā aronga matua, e hiahiatia ana ngā rauemi rerekē mō ia. Ina uru te wai ki roto i ngā rauemi ka pāngia te raru e te whānuitanga. Ka taea e te tokaro taketake te torotoro i ngā hurihuinga ruru-mātao e hokorua rau, kāore i tino whanui ake i te 300 huringa, engari kāore i te nui ake te tūponotanga o te pānga i te kōneo kāore i te whakarākei, ina tata noa ki te 50 huringa anake ka pakaru. Mō te tiaki i te ahi UV, ko ngā rauemi hangahanga e whai pāpaku motuhake ana i te tae tino pai ake i muri i ngā haora e hokowhā tekau mā waru e whai ana i ngā whakamātau arotini e ai ki ngā paerewa ASTM. Kei te pupuri tonu ēnei hangahanga i te 95% o rātou tae tuatahi, engari he tere noa te māmāri o ngā rakau paratete mēnā kāore i te kōpae ia tau pea. Ko te haumārui te mea nui rawa atu mō ngā mata e makona ana. Ko ngā rauemi hangahanga e whai takotoranga ana, me ngā tokaro e whai āwhawa ana e neke ake ana i te 0.65 ki te āpure COF ā-kinetic, e tino pai ake ana i te mea e here ana a OSHA mō ngā ara toki-toki taiwhenua e 0.50 ake nei te itinga.
| Rauemi | Manawaroa Tōkei-Tākiri | Te Taumata Whakapōpouri o te Aotūroa | Te Rātonga COF Māuao |
|---|---|---|---|
| Kōhatu Tūturu | Tino pai (300+ ngota) | Whakamārie māmā | 0.60–0.80 |
| Rakau Tino Nui | He iti noa (pakaru ki te 75 ngota) | Teitei kāore he rāpoi | 0.45–0.55 |
| Ngota | Pai (200 ngota) | Minimara (<5% whakamāmā) | 0.65–0.85 |
Mātātoko Ora: Hardwoods Tuarangi vs. Tōpito Composite Hōuia Waho
Ko te wā ora me te nui o te mahi e hiahiatia ana he rerekē tēnei i te whakaputa ake i ngā matērahi tawhito ki ngā kōwhiringa hangarau hou. Hei tauira, ko ngā rakau paraire pērā i te Ipe me te Cumaru. E taea ana e ēnei rakau te ora ake i te 25 tau nekehanga rānei i ngā wāhi punahiko rawa, engari ko te utu he nui. Me miraka ngā rakau nei i te rua wā i te tau, me whakauru tika ki ngā tikanga āhuarangi ā-rohe. Ki ngā wāhi maroke, ka pakaru pea ratou mōhio. Mēnā ko ngā raki rākau i raro ake i te freezing? Kia tatari ki ngā herenga o te raki e mōhiotia ana anō hoki. Ina tirohia ngā matērahi karaihe o nāianei, nā ngā resin pūropi nā ngā minerahi me ngā takotoranga fibre-glass kei roto. Ka whakarite ngā kaihanga i ēnei hua ka pai te mahi mo te 15 tau pērā anō i te kore whakamahinga. Ko te pānui hoki e korerotia ana. Ko ngā rakau paraire e utua ana i te 40% atu anō i te wā i te nuinga o te wā nā te hiahia ki te whakahou anō me ngā whakakapi mutunga. Kāore ngā karaihe anō hoki i te kore raruraru. Ko te mea e kiia nei ko 'span limitations' me titiro noa. Mēnā ka whakauruhia kāore he tautoko i runga ake i te 16 ineti, ka ngoikera pea ngā matērahi nei i raro i tō rātou ake taumaha.
| Matua | Rakau Tino Nui | Taputapu Composite |
|---|---|---|
| Roanga Wā Maamaa | 20–30 tau | 10–15 tau |
| Te whakahaere i ia tau | 6–8 haora | <1 haora |
| Māmā o te Āhuarangi | Purutu whati | Te whakapūmau ā-wāhi |
Ngā Hiahia Whakahaere Motuhake mō te Āhuarangi mō ngā Taputapu Taura Taumata Waho
Ko te tiaki tika i ngā tapa waho he mea nui te mārama ki te urupare o ngā matēria rerekē, tāpirihia anō hoki ngā tikanga āhuarangi takotoranga. Mō ngā tapa kauri me te redwood, ko te whakaputa hinu kia kotahi te wā i te tau hei aukati i ngā tohumātā karaka e hua mai ana i te pānga o te ao mārama, ā, ka pupuri hoki i te wai. He wehe atu te take mō te limestone, īt especially ēnei wāhi e reri ana, e parurenga ana haere tonu. Me whakamahi kaihoroi māmā ai kia kaua e huakina te mata kōhatu, ā, me pepeha kia rua ngā wā i te tau e ngā tikanga ASTM pērā i te C97-18. Ki te mea e pā ana ki ngā tapa huinga kei ngā taiao makariri, ko te horoi marino me te sap mainomai ia toru marama anō hei aukati i te tipu o te mūra. Me tiaki hoki ngā rawara taiwhenua, me ngā horoi mainomai e whā ngā wā i te tau hei whawhai i te hinganga o te paraumu ahakoa he aha te matēria. Kei ngā rohe koruhea, e pōhara ana ngā tapa rākau me ngā huinga ki te panonitanga o te wera, kia rongo ai ki ngā aukati UV. Ko te tiaki tataungia e ōrite ana ki ēnei āhuatanga āhuarangi e taea ai te tuarua, te tuatoru rānei i te ora o ngā punaha tapa mō te kore tiaki. I whakaatu tēnei kitenga te Rōpū Kōrero Mātāpona Whenua i te tau 2025 i muri i te whakamātau roa i te marae.
Ngā tikanga o te whakapuaki, te hūmāni, me te horoi mō ngā papa tākarotia o waho mō te kahikatea, redwood, limestone, me ngā tākarotia āhuarangi
- Rākau pū (Cedar/Redwood) : Whakapuaki i te hinu e uru ana ia 12–18 marama; kaua e whakamahi i ngā kaimātai pēhikara e pakaru ai te wai. Horoi ki te pēhi pani i te ά1,200 PSI kia kaua ai e marere ngā aho.
- Kōpūpū parae : Hūmāni ia 24 marama ki ngā kaimātai e whiti ana; whakamahi i ngā kaihoroi kāore he paraihe kia tiakina te calcium carbonate.
- Ngota : Horoi ia marama ki ngā rāwaro he karuwhenua kia kaua ai te ūpoki; kaua rawa e whakamahi i ngā taputapu orohine e kino ai te mata o te rākau.
Te arataki haumaru me ngā paerewa mō te pānga ki te takotoranga mō ngā papa tākarotia o waho
Te whakaaetanga ASTM F2979-23, Ngā inenga COF mō te horanga (ά0.6), me te whakamātau pono i te taraka i te ao reo
Ina te haere ki ngā ataamira tūmatanui e maroke ana i te ua, i te hukapapa, i te parurenga hao ranei, kāore e taea te wareware ki ngā paerewa haumaru. Ko te paerewa ASTM F2979-23 te mea e whakamārama ana i te tikanga mataroa mō te pātiki o ngā mata wet, e hiahiatia ana kia iti noa 0.6 te tauira āhuatanga pātiki ina whakamātauria e ngā tikanga e whakaaturia ana i te ua ake. Ka āwhina tēnei momo whakaritenga kia iti ake ngā waahanga e pati ana i te wā e nui ana te wai. Engari ko te take: kāore ngā nama mai i ngā whakamātautau taiao e ū ana ki ngā ahuatanga i te ao tūmatanui. Ngā mea pērā i te pāpaku e tipu ana ki ngā mata, ngā rākau e huihui ana i waenganui i ngā tapawhā, i ngā pakanga iti rānei e hangaia ana i ngā wā o te hukapapa-tautoko ka hāngai ki te āhua pai pea o ēnei paerewa. E ai ki ngā raraunga OSHA i tirohia i runga i ētahi atamira hanganga, ko ngā kaupapa e whakamahia ana i ngā taputapu kua whakaaetia e tēnei paerewa e kitea ana he iti ake te 40% o ngā horapata e hāngai ana ki te patipati. Nō reira ina kōwhiringa i ngā tapawhā ātea, titiro ki ērā e manakohia ana e tētahi taha tuatoru me ngā tuhinga COF tino. Kaua e wareware ki te tirotiro mēnā ka pātiki tonu rātou ahakoa i te takotoranga kino i te wā roa.
Ngā Huarahi Takirua Tau 2026 mō ngā Tapawhā Taiepa
Ngā Kowhatu Maiti Kakara, Ngā Huinga Kōpae-Koata Whakawhiti, me ngā Paraire Bio-Polymer e Pū ana i te Aho Kiri
Kei te pāhono te hanganga o ngā arataki taumata waho i ngā panoni nui e toru ana. Kei te whakapūria ēnei inlay metara, nō te mira kua tuhingia rīwhi rīwhi, ki ngā matērihi hihiri me ngā mata oneone. Ka pai ake te pā ki ngā wa wetewete, ā, kāore hoki i te mātotoru i te wā roa. Ko tētahi atu whanaketanga ko ngā karawhiti oneone e huinga ana i te paraihe kua waro me ngā pāpaku kua whakamahia anō. Ko te matērihi e hua mai ana he anawai iti e tuku ai te wai ki waho, ka iti ake ngā mōrearea taraiwa umuaro, e 30% pea, ā, e ai ki ngā whakamātautau hou. Mō te hunga e whai mōhio ana ki te roa o te āhua, kei te waipiro anō hoki ngā karuwhiti bio polymer e hua mai ana i ngā resin pūtake tipu. Ka mau tonu ō rātou tae kaha mō te neke atu i te 15 tau, arā, ka iti ake te hiahia ki te paina anō, ki te whakakapi rānei. Ko ēnei whanaketanga katoa e tohu ana i te haere whakamua nui ki ngā arataki e tino haumaru ana, e roa ana, ā, e pai ake hoki mō te taiao.
