E tele igoa eseese mo le pito i fafo o le hexagonal bolt, mo se faʻataʻitaʻiga, e mafai ona taʻua o le pito i fafo o le hexagonal bolt, mo se faʻataʻitaʻiga, e mafai ona taʻua o le pito i fafo o le hexagonal bolt. E mafai foi ona taʻua o le pito i fafo hexagonal bolt. E tutusa uma le uiga o lenei mea. Pau lava le mea e ese ai masani a le tagata lava ia. Ina ua uma le vevela galvanizing luga togafitiga, e maua aafiaga anti-corrosion.
1. ua vaevaeina fa'amau masani i le a, b ma le c. O mea muamua e lua o pa'u mama, e seasea fa'aaogaina. I le tulaga masani, o fa'amau masani e fa'asino ile Vasega C fa'amau masani.
2. Vasega C masani fa'amau e masani ona fa'aogaina i nisi o feso'ota'iga le tumau ma feso'ota'iga e mana'omia le fa'a'ese'ese. O fa'amau masani e masani ona fa'aogaina i fausaga faufale o le M16, M20 ma le M24. O nisi fa'amau fa'atauva'a i le alamanuia fa'ainisinia atonu e lapopo'a tetele ma fa'amoemoe fa'apitoa.
malosi maualuga u'u fa'amau fa'amau
3. O mea o loʻo i ai le malosi maualuga e ese mai le faʻamau masani. E masani ona faʻaaogaina faʻamau malosi mo soʻotaga tumau. E masani ona fa'aaogaina o le M16~M30.
O le ipu tautau tutusa e faʻaaogaina mo le fesoʻotaʻiga i le va o le tasi ipu ma le tasi ipu, ma le va o le tasi ipu ma le lua ipu. E mafai ona suia na'o le umi o le fa'apotopotoga, ae le o le feso'ota'iga itu. O le ipu tautau tutusa e tele lava ina faia i le ipu uamea e ala i le faailogaina ma le tipiina. O le fa'atinoga o le fa'atinoga o le pito i fafo o le hexagon bolt e aofia ai numera e lua, lea e fa'atusalia ai le numera o le malosi o le ma'a'a ma le fua fa'atatau o le malosi o mea.
Mo se faʻataʻitaʻiga, o faʻamau e iai le vasega faʻatinoga 4.6 o lona uiga:
a. Mea fa'amau: malosi fa'aigoa fa'aigoa e o'o atu i le 400MPa;
e. Ole fua ole fua ole mea faʻapipiʻi ole 0.6;
i. Ole malosi ole fua ole mea faʻapipiʻi e oʻo atu ile 400 × 0.6 = 240mpa grade
O paʻu malosi maualuga ma le faʻatinoga o le 10.9 e mafai ona ausia manaʻoga nei pe a maeʻa togafitiga vevela:
a. O mea faʻapipiʻi, malosi faʻapitoa e oʻo atu i le 1000MPa;
e. Ole malosi ole fua ole mea faʻapipiʻi e oʻo atu ile 1000 × 0.9 = 900MPa vasega
