He aha ngā rerekētanga me ngā āhuatanga ōrite i waenga i te maitai koki waewae-kore ōrite me te maitai koki waewae-rite?

Rino koki piauaue rua ngā taha he rite te roa, e hanga ana i tētahi hanganga koki-matau tino ōrite. Ko tētahi whakatakotoranga noa, pērā i te ∠50×50×5, e tohu ana ko ngā taha e rua he 50 mm te whānui, ā, he 5 mm te matotoru. Nā tōna āhua ōrite me te tohatoha ahotea ōrite, he maha ngā wā ka whakamahia i roto i ngā hanganga e hiahia ana kia rite te kawenga.

Waewae-kore-tauritepae koki kua whakakikoruatia, e ai ki te ingoa, e rua ngā taha he rerekē te roa. Hei tauira, ko te ∠100×80×8 e tohu ana i te taha roa o te 100 mm, te taha poto o te 80 mm, me te matotoru o te pakitara o te 8 mm. Mā tēnei hoahoa kore-taurite ka taea e ia te whai wāhi motuhake ahakoa i roto i ngā hanganga kore-taurite, i raro rānei i ngā here ā-wāhi motuhake, ka taea ai te whakamahi rauemi tino pai.

1. He ōrite ngā roa taha o te maitai koki waewae-rite; hei tauira, ko te maitai koki Nama 4 e whakamahia whānuitia ana e pā ana ki te maitai koki 40×40×4. Ko te "40x40" e tohu ana ko ngā taha e rua he 40 mm; ki te rite te roa o ngā taha e rua, he maitai koki waewae-rite; engari ko te maitai koki waewae-rite he rerekē ngā roa taha, me te roa o tētahi taha i tētahi;
2. Ko ngā whakatakotoranga mō te maitai koki waewae-rite kei waenga i te Nama 2 ki te Nama 20; ko ngā whakatakotoranga mō te maitai koki waewae-rite kei waenga i te ∟50*32 ki te ∟200*125;
3. He whānuitia te whakamahinga o te maitai koki ōrite i roto i ngā hanganga hangarau pēnei i ngā piriti, ngā pourewa tuku, ngā mīhini hiki me te kawe, ngā kaipuke, me ngā whata whare putunga; he whānuitia te whakamahinga o te maitai koki ōrite-waewae i roto i ngā hanganga ahumahi ā-tāone, ā-iwi, ā-iwi, me ngā hanganga hōia, pēnei i ngā kurupae whare ahumahi, ngā oumu ahumahi, ngā pourewa tauhohenga, me ngā whata ipu. Nā te mea he iti ake te rahinga e whakamahia ana i te maitai koki kotahi-waewae, he nui ake te utu.

1. Ko te rauemi o te waewae ōritekoki maitaime te waewae kore tauritepae kokihe rite tonu: te maitai koki Q235B me te maitai koki Q345B;
2. Ko ngā roa paerewa ko: te maitai koki 6m, te maitai koki 9m, me te maitai koki 12m;
3. He rite tonu te tikanga tatau: Taumaha mō ia mita = 0.00785 * (Whānui taha + Whānui taha - Matotoru taha) * Matotoru taha.
