Kumenyekanisha ibicuruzwa
Inkunga yingirakamaro ikoreshwa muguhuza imirongo myinshi ya trusses kugirango hamenyekane ituze hamwe nimbaraga imwe yikiraro cya truss.Ikadiri yingoboka irashobora guhuzwa hejuru ya chord yo hejuru cyangwa inkoni ihagaritse.
Hano hari ibice bitandatu bisanzwe byo gushyigikira (bizwi kandi nk'amakaramu y'indabyo, idirishya ry'indabyo);
Ubwoko 321 nibisanzwe: Ikadiri yingoboka 450, ikadiri yo gushyigikira 900, ikadiri yo gushyigikira 1350;
Ubwoko 200 nibisanzwe: 480 ikadiri yo gushyigikira itambitse, 480 ikadiri yo gushyigikira ihagaritse, 730 ikadiri yo gushyigikira itambitse, 730 ikadiri yo gushyigikira.
Inkunga yingoboka nuburyo bukurikira: ikadiri yingoboka ikoreshwa muguhuza umurongo wambere numurongo wa kabiri wa trusses.Imirongo ibiri-imwe-igorofa ya Bailey icyuma, hagati yubuso bwo hejuru bwa buri truss (cyangwa chord ikomezwa), ikadiri yo gushyigikira yashyizwe mu buryo butambitse.Kubireba imirongo ibiri nuburyo bubiri, usibye gushiraho ikadiri yingoboka hejuru yubuso, hagomba gushyirwaho ikadiri yingoboka kumurongo winyuma winyuma ya truss yo hejuru (inkoni imwe ihagaritse kumpera yimbere yicyiciro cya mbere cya truss nayo igomba gushyirwaho).Iyo wubatse ikiraro cyimirongo itatu, ikibanza numubare wamafranga yingirakamaro ni nkayo kubiraro bibiri.Mugihe ushyiraho, shyiramo amaboko 4 yubusa kumpande zombi mumurongo wo gushyigikira umwobo wimirongo ibiri ya trusses, hanyuma ubikosore hamwe na bolts.
Mu kiraro cya etage, ibyinshi mubikoresho byingoboka ni 900 cyangwa 1350, kandi hariho na sisitemu yihariye yo guhuza inkoni ukurikije ibikenewe, kandi inyinshi murizo zashyizweho hamwe na bolts.
