Kwizirika nibintu byingenzi mubikorwa byubukanishi nubuhanga, cyane cyane bikoreshwa muguhuza no kurinda ibice bibiri cyangwa byinshi, byemeza ko imiterere ihamye kandi yizewe. Ziza muburyo butandukanye kandi zikoreshwa cyane mubice byingenzi, harimo inganda zinganda, ubwubatsi, amamodoka, nindege.
Mu buryo bwubaka, ibifunga mubisanzwe bigizwe numutwe na shanki, bigera ku gufunga binyuze mumutwe cyangwa izindi mashini. Ibifunga cyane cyane birimo bolts, screw, nuts, koza, na rivets. Bolt na nuts bikoreshwa hamwe, bisaba pre - byacukuwe mu bice bihuza no gukomera imbuto kugirango umutekano uhuze. Imiyoboro irashobora guhurizwa mu mwobo wa - cyangwa mu bikoresho, bikuraho ibikenerwa byongeweho. Abamesa bakwirakwiza igitutu kugirango birinde kugabanuka cyangwa kwangirika hejuru yubusabane. Imiyoboro, ifite umutekano mukuvugurura, irakwiriye kubihoraho, bitari - byimurwa.
Guhitamo ibintu bifatika bifata neza imikorere yabo nibisabwa. Ibyuma bisanzwe bya karubone bifata igiciro gito nimbaraga ziciriritse, bigatuma zikoreshwa cyane mubikorwa rusange byinganda. Ibyuma bidafite ibyuma bitanga imbaraga zo kurwanya ruswa kandi birakwiriye gukoreshwa mubushuhe cyangwa imiti yangiza. Alloy ibyuma cyangwa titanium alloy bifatisha bikoreshwa murwego rwo hejuru - imbaraga, hejuru - ibidukikije byubushyuhe cyangwa mugusaba ibisabwa nkikirere. Ubuvuzi bwo hejuru nka galvanizing, fosifate, cyangwa Dacromet coating irashobora kurushaho kongera imbaraga zo kurwanya ruswa hamwe nubuzima bwa serivisi bwiziritse.
Mu musaruro w’inganda, kwihutisha ubuziranenge ni ngombwa. Ibipimo mpuzamahanga (nka ISO), ibipimo byigihugu (nka GB na ANSI), hamwe ninganda zinganda zituma habaho guhinduranya no guhuriza hamwe kwizirika, bikagabanya cyane ibiciro byo gushushanya no kubungabunga. Hamwe niterambere ryinganda zubwenge, tekinolojiya mishya yihuta, nkimbaraga - imbaraga, kwifungisha - gufunga, hamwe nuburemere, biragaragara, bigenda bitera imbere murwego rwo hejuru - inganda zikora ibikoresho.
Nka "ihuriro" ryubukanishi, kwizirika, nubwo ari bito, nibyingenzi, kandi kwizerwa kwabo bifitanye isano itaziguye nibikorwa byumutekano. Mu bihe biri imbere, hamwe niterambere ryibikoresho siyanse nubuhanga, abizirika bazakomeza kwiteza imbere bagana ku mikorere myiza no mu bwenge, batanga ubufasha bukomeye bwa tekinike ku nganda zitandukanye.
