Whakatika: He reera karāhe katoa a Viewmate
Ko te matotoru o te karāhe e whakamahia ana mō ngā arawhata (i te nuinga o te wā mōngā papa ārai, ngā ringaringa, ngā takahanga, ngā ara whakaara rānei) ehara i te uara pumau—e whakawhirinaki ana ki te momo karāhe, te whakamahinga (ngā whakaritenga haumaru), te kawenga hanganga, me ngā ture hanga ā-rohe. Kei raro nei he whakamārama taipitopito o ngā matotoru noa, ngā whakaaro matua, me ngā tohutoro waehere hei whakarite i te haumaru me te tutuki i ngā whakaritenga:
1. Momo Karāhe Matua mō ngā Arawhata: Me "Karāhe Haumaru"
Tuatahi,me hanga ngā karāhe katoa e whakamahia ana i ngā arawhata hei karāhe haumaru(e ai ki ngā waehere hanga whare ā-ao pērā i te US IRC, EU EN 12150, te GB 15763.2 rānei a Haina). Mā tēnei ka ārai i te pakaru kino ki ngā maramara koi. Ko ngā momo matua e rua ko:
- Karāhe Whakamarumaru (Karāhe Haumaru Whakakahangia-Wera)Ko te kōwhiringa tino noa—e 5 ngā wā ka kaha ake i te karāhe noa, ā, ka pakaru ki ngā wahi iti, rite ki te mataono.
- Karāhe WhakakirikiriE rua, neke atu rānei ngā paparanga karāhe e herea ana ki tētahi paparanga polymer (hei tauira, PVB). Ahakoa pakaru, ka mau tonu ngā kongakonga i te paparanga, ā, he mea tino pai mō ngā wāhi morearea (hei tauira, ngā arawhata, ngā arawhata o waho).
2. Te Matotoru o te Karāhe Noa mā te Whakamahinga
He rerekē te matotoru i runga i te whakamahinga o te karāhe mō tētahiārai, ārai ringa, rāneitakahanga/whakaara(kawe-kawenga vs. kore-kawenga).
| Tono | Momo Karāhe | Awhe Matotoru Noa | Whakaaro Matua |
| Papa Arapae (Panui) | Kua whakamahanatia / Kua whakakikoruatia | 8mm – 12mm | Kāore e mau kawenga (ka ātete noa ki te pēhanga taha, hei tauira, te piko). He 8mm te whānui mō ngā whare noho; 10–12mm mō ngā pakihi (he nui ake te haere o ngā waewae). |
| Pupuri arawhata | Kua whakamahanatia / Kua whakakikoruatia | 15mm – 25mm | Me tautoko i te pēhanga ā-ringa (50–100N mō ia waehere). Mā te karāhe matotoru (hei tauira, 20mm) ka pakari, ka roa hoki te mau. |
| Papa arawhata (Papa karāhe) | Papa Whakakī (Papa Whakamarumaru) | 25mm – 40mm | Te amo i te kawenga: Ka tautoko i te taumaha tangata (iti rawa 500kg/m²). Ko te tikanga he 2–3 paparanga karāhe kua whakapakeketia (hei tauira, 2x12mm + PVB = 25mm katoa) mō ngā whare noho; 30–40mm mō ngā whare arumoni. |
| Te Whakaara o te Arawhata (Papa Poutū) | Kua whakamahanatia / Kua whakakikoruatia | 8mm – 10mm | Kāore e mau kawenga (hei ātaahua noa iho). He angiangi ake i ngā papa, nā te mea kāore e hiahiatia kia ātete ki te kaha taha. |
3. Ngā Take Matua e Pā Ana ki te Matotoru
Haunga te whakamahinga, mā ēnei āhuatanga e whakatau te matotoru whakamutunga e hiahiatia ana:
- Ngā Waehere Hanga WhareNgā ture ā-rohe (hei tauira, USTe Waehere Noho ā-Ao (IRC), EUEN 13474) me whakarite kia iti rawa te kaha me te matotoru. Hei tauira, me tu atu ngā ārai arawhata i te 200 lbs (90kg) o te kaha e pā ana ki te whakapae—tērā pea me matotoru ake te karāhe mō ngā ārai teitei ake.
- Whānuitanga (Tawhiti i waenganui i ngā Tautoko)Mō ngā papa ārai, me whakamahi karāhe matotoru ake ngā whāwhātanga roa ake (hei tauira, 1.5m vs. 0.8m) kia kore ai e piko, e pakaru rānei. Tērā pea ka pai te karāhe 10mm mō te whāwhātanga 1m, engari me whakamahi pea he 12mm mō te whāwhātanga 1.2m.
- Ngā Whakaritenga UtainaKo ngā arawhata mō ngā wāhi arumoni (hei tauira, ngā toa hokohoko, ngā tari) me matotoru ake i ngā arawhata noho, nā te mea me tautoko e rātou ngā kawenga hihiri teitei ake (hei tauira, he tini tāngata, he mea wira).
- Ngā Āhuatanga TaiaoKo ngā arawhata o waho, ngā arawhata rānei i ngā wāhi makuku (hei tauira, ngā puna kaukau e tata ana ki ngā arawhata) ka whakamahia pea he karāhe whakakikorua matotoru hei ātete i te huarere me te waikura.
4. Ngā Tauira o ngā Horopaki
Hei hanga i tēnei raima, anei ngā whakaritenga o te ao tūturu:
- Papa Arapae Noho: karāhe whakamaroke 10mm (whānuitanga ≤1m, teitei 900mm).
- Papa Karāhe Noho: karāhe whakakikoruatia 25mm (paparanga PVB 2x12mm kua whakamaroketia + paparanga PVB 1mm).
- Pupuri arawhata arumoni: karāhe whakamaroke 20mm (e tautoko ana i te kaha 100N, teitei 1.1m).
- Papa Arapae o Waho: karāhe whakakikoruatia 12mm (ātete ki te hau, te ua, me ngā huringa pāmahana).
5. He Pānui Haumaru Hira
Kaua rawa e whakamahiakarāhe kua whakamahanatia (noa)mō ngā arawhata—ka pakaru ki ngā wahi koi, mōrearea. Me manatoko tonu kua whakamanahia te karāhe hei karāhe haumaru (rapua ngā tānga pēnei i te "TEMPERED" "LAMINATED" rānei i te taha) ā, kei te tutuki te tāutanga i ngā ture hanga ā-rohe (me whakaū tēnei e te kaimahi kirimana ngaio, e te miihini hanganga rānei).
Hei whakarāpopototanga, ko te matotoru o te karāhe arawhata kei waenganui i te8mm (ngā ara whakarunga/ngā papa ārai)ki40mm (ngā takahanga arumoni), me te uara tika e whakatauhia ana e te tono, te waehere, te whānuitanga, me te kawenga. Me matua whakarite tonu te karāhe haumaru me te tutuki i ngā ture ā-rohe.
