Ngā tohu huarahiHe rama ture ngā rama e tohu ana i ngā waka me ngā kaihaerere kia haere tonu, kia tū rānei i runga i ngā rori. Ko te nuinga o ēnei he rama tohu, he rama ara, he rama whakawhiti. Ko ngā rama tohu he taputapu e whakaatu ana i ngā rama waka mā te whakamahi i tētahi raupapa o ngā rama whero, kōwhai, me te kakariki. He mārama ngā ture kua tautuhia e ngā whenua huri noa i te ao, ā, he rite tonu te nuinga mō te tikanga o ngā tae rerekē i roto i ngā rama tohu. E toru ngā rahi e wātea ana mō ngā waeine rama tohu: 200mm, 300mm, me te 400mm.
Ko te whānui o ngā kōhao whakapiri mō ngā rama tohu whero me te kakariki i runga i te whare tohu he 200mm, 290mm, me te 390mm, ia, me te manawanui o te ±2mm.
Mō ngā rama tohu kāore i te tauira, ko ngā diameter o te mata e whakaputa ana i te mārama o ngā rahi 200mm, 300mm, me te 400mm he 185mm, 275mm, me te 365mm, ia, me te manawanui o te ±2mm. Mō ngā rama tohu he tauira, ko ngā diameter o ngā porowhita porowhita o ngā mata e whakaputa ana i te mārama o ngā whakatakotoranga e toru o Φ200mm, Φ300mm, me te Φ400mm he Φ185mm, Φ275mm, me te Φ365mm, ia, ā, ko te manawanui rahi he ±2mm.
He maha ngā momo noa ongā rama tohu whero me te kakarikii Qixiang, tae atu ki ngā rama waka motuka, ngā rama kore-waka motuka, ngā rama whakawhiti hikoi, me ētahi atu. E ai ki te āhua o ngā rama tohu, ka taea te wehewehe i ēnei hei rama tohu ahunga, rama whakatūpato kanapa, rama tohu whakakotahi, me ētahi atu.
Muri iho, ka whakaurua ngā teitei tāutanga o ngā momo rama tohu.
1. Ngā rama whakawhiti:
Me toru mita te teitei.
2. Ngā rama whakawhiti hikoi:
Tāutahia ki te teitei o te 2 ki te 2.5 mita.
3. Ngā rama o te ara:
(1) Ko te teitei o te tāutanga he 5.5m ki te 7m;
(2) Ina tāutahia ki runga i te arawhata, kaua e tino iti iho i te āputa o te piriti.
4. Ngā rama tohu mō ngā ara waka kore-mīhini:
(1) Ko te teitei o te tāutanga he 2.5m ~ 3m. Mena he pou rama waka kore-mīhini he mea whakarara, me tutuki i ngā whakaritenga ā-motu o te 7.4.2;
(2) Me whakarite te roa o te wāhanga cantilever o te rama tohu waka kore-mōtini kia noho te pūnaha rama tohu waka kore-mōtini ki runga ake i te ara ūnga waka kore-mōtini.
5. Ngā rama waka, ngā tohu ahunga, ngā rama whakatūpato e kanapa ana, me ngā rama whakawhiti:
(1) Ka taea e ngā kaihanga tohu haumaru huarahi te whakamahi i te teitei tāutanga cantilever mōrahi o te 5.5m ki te 7m;
(2) Ina whakamahia te tāutanga pou, kaua te teitei e iti iho i te 3m;
(3) Ina tāutahia ki te tinana piriti o te arawhata, kaua e iti iho i te āputa o te tinana piriti;
(4) Kaua te roa mōrahi o te wāhanga cantilever e neke ake i te pokapū whakahaere ara o roto rawa, ā, kaua te roa iti rawa e iti iho i te pokapū whakahaere ara o waho rawa.
Neke atu i te tekau tau o te wheako o Qixiang ki ngā rama tohu, ā, he rama tohu mana-teitei, he rama tohu mana-iti,ngā rama tohu hikoi whakauru, ngā rama tohu rā, ngā rama tohu waea pūkoro, me ētahi atu. Ko te huarahi pai ki te whiriwhiri hua ko te haere tika ki ngā kaihanga rarawe me te kore e manukanuka ki ngā taurangi ratonga muri-hoko. Nau mai haere mai ki te tirotiro i te papaanga.
