Incamake ya Rebar
Rebar isanzwe izwi nkubushyuhe buzengurutse urubavu. Urwego rwibisanzwe rushyushye ruzengurutswe rugizwe numusaruro muto wa HRB n amanota. H, R na B ninyuguti zambere zishyushye zizungurutse, Urubavu na Bars. Rebar irashobora kugabanywamo ibyiciro bitatu ukurikije imbaraga: HRB300E, HRB400E, HRB500E, HRB600E, nibindi.
Urudodo rwerekana urutonde rwa rebar muri rusange 6-50mm. Mubisanzwe turimo byinshi ni 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm nibindi. Gutandukana byemewe kwigihugu: 6-12mm gutandukana muri ± 7%, 14-20mm gutandukana ± 5%, 22-50mm gutandukana ± 4%. Mubisanzwe, uburebure bwagenwe bwa rebar ni 9m na 12m, muribwo 9m z'uburebure bukoreshwa cyane cyane mukubaka umuhanda usanzwe naho umugozi muremure wa 12m ukoreshwa cyane mukubaka ikiraro.

| Inzira yumusaruro | Rebar ni icyuma gifite uburebure bwurubavu, bizwi kandi ko gushimangira urubavu, mubisanzwe bifite imbavu 2 ndende kandi imbavu ihinduranya ikwirakwizwa ku burebure. Imiterere y'urubavu ruhindagurika ni imiterere izenguruka, imiterere ya herringbone n'imiterere y'ukwezi. Kubijyanye na milimetero ya diameter nominal. Diameter ya nominal yo gushimangira urubavu ingana na diameter nominal yumucyo uzengurutswe hamwe nigice kimwe. Diameter nominal yumurongo wibyuma ni mm 8-50 mm, naho diameter isabwa ni 8, 12, 16, 20, 25, 32 na 40. mm Utubari twa rubavu ahanini duhangayikishwa cyane na beto. Urubavu rwicyuma rushobora kwihanganira ibikorwa byimbaraga zo hanze kubera ingaruka zurubavu na beto. Utubari twa rubavu dukoreshwa cyane mubyubatswe bitandukanye, cyane cyane binini, biremereye, byoroheje binini bikikijwe n'inzu ndende. |

| Gusaba | Rebar ikoreshwa cyane mubwubatsi, ikiraro, umuhanda nubundi bwubatsi bwububatsi. Kuva mumihanda, gari ya moshi, ikiraro, umuhanda, umuyoboro, kurwanya umwuzure, urugomero nibindi bigo rusange, kugeza umusingi winyubako, imirishyo, inkingi, inkuta, amasahani, ibyuma bya screw nibikoresho byingirakamaro. Kubera ko Ubushinwa bugenda bwiyongera, imijyi ikenewe cyane mu iyubakwa ry’ibikorwa remezo ndetse n’iterambere ry’imitungo itimukanwa. |
