He maha nga ingoa rereke mo te putea hexagonal o waho, hei tauira, ka taea te kii ko te putea hexagonal o waho, hei tauira, ka taea te kiia ko te hexagonal o waho. Ka taea hoki te kiia he pou hexagonal o waho. He rite tonu te tikanga o tenei katoa. Ko te mea he rereke nga tikanga whaiaro. I muri i te maimoatanga mata piauau wera, ka tutuki te paanga anti-corrosion.

1. ka wehea nga tutaki noa ki a, b me c. Ko nga mea tuatahi e rua he raka parakore, he iti nei te whakamahi. I te nuinga o te korero, ko nga raka noa e tohu ana ki te karaehe C nga tutaki noa.

2. Ka whakamahia nga tutaki noa o te akomanga C ki etahi hononga rangitahi me nga hononga e hiahia ana kia wetewete. Ko nga tutaki noa e whakamahia ana i roto i nga hanganga whare ko M16, M20 me M24. Ko etahi o nga raka i roto i te ahumahi miihini he nui nga diameter me nga kaupapa motuhake.

te kaha o te kaha kaha o te hopu waku

3. He rereke nga mea o te raka kaha teitei mai i tera o te raima noa. Ka whakamahia nga tutaki kaha teitei mo nga hononga pumau. Ko M16~M30 te nuinga o te whakamahi.

Ka whakamahia te pereti iri whakarara mo te hononga i waenga i te pereti kotahi me te pereti kotahi, i waenga i te pereti kotahi me te pereti rua. Ka taea anake te whakarereke i te roa o te huihuinga, engari kaore i te ahunga hononga. Ko te pereti iri whakarara te nuinga o te mea hanga ki te pereti maitai ma te tarai me te tapahi. E rua nga tau e tohu ana i te uara kaha tensile whakaingoa me te ōwehenga kaha tuku o nga rawa tutaki.

Hei tauira, ko te tikanga o nga tutaki me te karaehe mahi 4.6:

a. Rauemi raka: ka eke te kaha ki te 400MPa;

b. Ko te 0.6 te ōwehenga hua o te rauemi raka;

c. Ko te kaha tuku ingoa o nga rauemi raka tae atu ki te 400 × 0.6 = 240mpa tohu

Ka taea e nga pou kaha teitei me te tohu mahi o te 10.9 te whakatutuki i nga whakaritenga e whai ake nei i muri i te maimoatanga wera:

a. Ko nga mea raka, te kaha o te kaha ki te 1000MPa;

b. Ko te kaha tuku whakaingoa o te rauemi raka tae atu ki te 1000 × 0.9 = 900MPa te kōeke
