Tulaga Fa'alelei

O le fausaga o se alalaupapa u'amea e tele lava ina fa'apipi'i i fa'alava lagolago ma paipa uamea fa'aputuga. O lenei fausaga e iai tulaga lelei nei:

Māmā: E fa'apipi'i fa'ameamea fa'ameamea e fau mai u'amea maualuga, o le alalaupapa u'amea e fai si māmā.

Modularity: O le uiga autu o le alalaupapa uʻamea o lona modularity, lea e mafai ai ona vave faʻapotopotoina i alalaupapa trussed beam ma eseese spns ma uta e tusa ai ma manaoga.

Fausia vave: O vaega e mafai ona faʻagasolo muamua i uta ma faʻapipiʻi i luga o le nofoaga, faʻaleleia atili le saoasaoa o le fausiaina.

Malosi Fetuuna'i: E talafeagai mo le tele o tulaga eseese fa'afanua ma tulaga faufale.

Auala Feso'ota'i Lelei

O le fesoʻotaʻiga auala o le alalaupapa uʻamea o loʻo maua ai tulaga lelei nei:

So'oga u'ele'ele: E mafai ona fa'aogaina so'oga fa'apipi'i i fetaulaiga o u'amea i itu eseese, tulimanu, ma foliga. E leai se manaʻoga e faʻapipiʻi papatusi fesoʻotaʻiga poʻo puʻu vili i le uamea, faʻamautinoa le faʻamaoni o le vaega.

Fesoʻotaʻiga Bolt: Vaevae i ituaiga masani ma maualuga-malosi, e faigofie ona faʻapipiʻi, aemaise lava mo fesoʻotaʻiga faʻapipiʻi i luga ole laiga.

Feso'ota'iga Rivet: Rivets e masani lava ona faia i le carbon riveted sila masani ma palasitika lelei ma fa'atupu fa'atinoga i le pito i luga. O le faʻaogaina o fesoʻotaʻiga e laʻititi, faʻamalosia le tuʻuina atu e faʻatuatuaina, ma le lelei o asiasiga e saʻo.

Fa'atatauga Fa'atatauga Fa'atatau

O le alalaupapa u'amea ei ai tulaga lelei i tulaga nei:

Faʻalavelave Faʻafuaseʻi: O le alalaupapa uʻamea o loʻo i ai se faʻalavelave faʻalavelave faʻafuaseʻi ma galuega laveai, aemaise lava i le puleaina o lologa, paʻu, paʻu, ma le laveaʻi vave ma le laveaʻi, ma le maualuga maualuga.

Aafiaga o le Puipuiga o le Siosiomaga: E mafai ona toe faʻaaogaina le alalaupapa uʻamea, e masani lava 3-5 taimi, e ofoina atu se aafiaga lelei o le puipuiga o le siosiomaga.

I se aotelega, o le alalaupapa uamea o loʻo faʻaalia ai le fausaga mama, maualuga le faʻaogaina, faʻavave vave o le fausiaina, malosi fetuutuunai, auala faʻafesoʻotaʻi eseese, ma faʻaaliga lautele faʻaoga. O nei tulaga lelei e avea ai le alalaupapa uʻamea o se fofo lelei mo alalaupapa le tumau i fausaga faʻainisinia eseese.
