Whakaahuatanga whakaputa
Ko nga raka hanganga maitai he pou kaha teitei me tetahi momo waahanga paerewa. He pai te mahi whakamau, whakamahia i roto i nga hanganga maitai me te miihini ki te whakarei ake i te paanga o te whakamau. I runga i nga hanganga rino whanui, ko nga pou hanga maitai e hiahiatia ana ko te karaehe 8.8 neke atu ranei, me te karaehe 10.9 me te karaehe 12.9, ko enei katoa he raka hanganga maitai teitei.
Kei te whakamahia te nuinga o nga raka hanganga maitai i roto i te miihini hanga maitai ki te hono i nga tohu hononga o nga papaa maitai hanga maitai.
Ka wehea nga pou hanga maitai ki nga kutikuti kutikuti teitei-kaha me nga pou hexagonal nui-kaha. Ko nga raka hexagonal nui te kaha teitei no te reanga kaha teitei o nga wiri noa, ko te kutikuti kutikuti nga pou kaha teitei he momo pai ake o nga pou hexagonal nui-kaha teitei mo te hanga pai ake.
Nga take e tika ana kia aro ki te hanga
Ko te hanga o te raka hanganga maitai me matua whakakoi, katahi ka whakapakeke, me whakamahi te raka hanga maitai tuatahi ki te whakamahi i te momo whiri hiko o te whiri hiko, te whiri hiko ranei e taea ana te whakarite, a ko te raka o te hanganga maitai te whakakaha i te tono nui, me whakamahi te momo torque-shear mo te whakakoi whakamutunga o te torsion-shear me te momo whiri hiko me te momo whiri o te hanganga maitai, me whakamahi te whiri hiko, me te momo whiri o te tira hiko, me te momo o te tira o te raima. torsion-shear momo hanganga maitai tutaki. Nga pou hanga maitai hexagonal nui kei roto i tetahi raka, kotahi nati, e rua nga horoi. Ko te momo kutikuti awhiowhio te raka hanganga maitai, na te raka, te nati, te anga rino hexagoni nui hexagon u te hanga horoi.
