Rebar, ikunze kwitwaagakoresho ko kugarura, igira uruhare runini mu bwubatsi, itanga imbaraga zo gukurura zikenewe kugira ngo ishyigikire inyubako za beto. Ubwoko bw'icyuma gitoranywa mu mushinga akenshi biterwa n'uburemere bwacyo n'ikoreshwa ryacyo ryihariye, bityo abahanga mu by'ubwubatsi n'abubatsi bagomba kumenya ibi bintu.
Hari ubwoko bwinshi bwa rebar, buri bumwe bwagenewe porogaramu runaka. Ubwoko busanzwe burimo:
1. Icyuma cyoroshye cyo kugaruraho(Icyiciro cya 40): Ubu bwoko bufite imbaraga zo gutanga umusaruro wa psi 40.000 kandi bukunze gukoreshwa mu mishinga yo guturamo nko mu nzira z'imihanda n'inzira z'abanyamaguru. Kuba bworoshye kugorora no gukora.
2. Icyuma gikomeye cyane(Icyiciro cya 60): Iyi icyuma gifite imbaraga zo gutanga umusaruro wa psi 60.000 kandi kibereye gukoreshwa mu bucuruzi no mu nganda, harimo inyubako ndende n'ibiraro. Kongera imbaraga zayo bishobora kugabanya ikoreshwa ry'ibikoresho bitagize ingaruka ku buziranenge bw'inyubako.
3. Rebar ipfundikiye epoxy: Ubwo bwoko bupfundikiye epoxy kugira ngo burwanye ingese, bigatuma buba bwiza ku nyubako zihura n’ibidukikije bikomeye, nko mu mazi cyangwa ahantu hafite ubushuhe bwinshi.
4. Icyuma gikozwe mu cyuma kidakoresha ifu: Ibyuma bitagira umugese bizwiho kurwanya ingese cyane kandi bikoreshwa ahantu hakunze kwangirika cyane nko mu nganda zikora imiti n'inyubako zo ku nkengero z'inyanja.
Urwego rw'ubukana n'akamaro karwo:
Ingufu za rebar ni ingenzi mu kumenya ubushobozi bwayo bwo gutwara. Ingufu zo hejuru, nka grade 75 cyangwa 80, zitanga imbaraga nyinshi zo gukurura, bigatuma ikoreshwa mu mirimo ikomeye. Guhitamo grade y'imbaraga bigira ingaruka zitaziguye ku gishushanyo n'umutekano w'inyubako kuko bigira ingaruka ku mubare w'imizigo imbaho z'icyuma zishobora kwihanganira.
Mu gusoza, gusobanukirwa ubwoko butandukanye bwa rebar n'imbaraga zazo ni ingenzi cyane mu guhitamo ibikoresho bikwiye umushinga uwo ari wo wose w'ubwubatsi. Mu gusuzuma ikoreshwa ryihariye n'imiterere y'ibidukikije, abubatsi bashobora kwemeza ko inyubako zabo zikora neza kandi zitekanye.
