Rebar nizina risanzwe ryubushyuhe buzengurutse imbaho zicyuma. Urwego rwibisanzwe rushyushye ruzengurutse ibyuma bigizwe na HRB hamwe numusaruro muto wamanota. H, R, na B ninyuguti zambere zamagambo atatu, Hotroll, Ribbed, na Bars, kimwe.
Icyuma gishyushye cyometseho icyuma kigabanijwemo ibyiciro bitatu: HRB335 (icyiciro gishaje ni 20MnSi), icyiciro cya gatatu HRB400 (icyiciro gishaje ni 20MnSiV, 20MnSiNb, 20Mnti), nicyiciro cya kane HRB500.
Rebar ni urubavu rw'icyuma hejuru, ruzwi kandi nk'icyuma cy'urubavu, ubusanzwe rufite imbavu 2 ndende kandi imbavu zinyuranye zigabanywa ku buryo burebure. Imiterere y'urubavu ruhindagurika ni umuzenguruko, herringbone n'imiterere y'ukwezi. Byerekanwe muri milimetero ya diameter nominal. Diameter nominal yumurongo wimbavu ihuye na diameter nominal yumuzingi uzengurutswe. Diameter nominal ya rebar ni mm 8-50, naho ibipimo bisabwa ni 8, 12, 16, 20, 25, 32, na 40 mm. Utubari twibyuma twibasiwe cyane cyane na stress ya beto. Bitewe nigikorwa cyurubavu, ibyuma byimbavu bifite ubushobozi bwo guhuza hamwe na beto, kuburyo bishobora guhangana neza nibikorwa byimbaraga zo hanze. Utubari twibyuma dukoreshwa cyane muburyo butandukanye bwubaka, cyane cyane binini, biremereye, byoroheje-bikikijwe n'inkuta ndende.
Rebar ikorwa ninganda ntoya. Ubwoko bwibanze bwurusyo ruto ni: gukomeza, igice-gikomeza n'umurongo. Byinshi mubishya kandi bikoreshwa-insyo ntoya zizunguruka kwisi birakomeza rwose. Uruganda ruzwi cyane rwa rebar ni rusange-intego-yihuta yo kuzunguruka rebar hamwe na 4-ibice byinshi-byongera umusaruro.
Inyemezabuguzi ikoreshwa mu ruganda ruto rudasanzwe rusanzwe muri rusange ni fagitire ikomeza, uburebure bw'uruhande muri rusange ni 130 ~ 160mm, uburebure muri rusange ni metero 6 ~ 12, naho uburemere bumwe ni toni 1.5 ~ 3. Imirongo myinshi izunguruka itunganijwe muburyo butambitse kandi buhagaritse, kugirango ugere kumurongo utagira umurongo. Ukurikije fagitire zitandukanye hamwe nubunini bwibicuruzwa byarangiye, hariho 18, 20, 22, na 24 inganda ntoya, naho 18 nizo nyamukuru. Kuzunguruka mu tubari ahanini bifata inzira nshya nko gukandagira itanura ryo gushyushya, amazi yumuvuduko ukabije wamanutse, ubushyuhe buke, no kuzunguruka bitagira iherezo. Kuzunguruka bikabije no kuzunguruka hagati biratera imbere mu cyerekezo cyo guhuza na bilet nini no kunoza neza kuzunguruka. Kunoza neza n'umuvuduko (kugeza 18m / s). Ibicuruzwa bisobanurwa muri rusange ф10-40mm, kandi hariho ф6-32mm cyangwa ф12-50mm. Ibyiciro byibyuma byakozwe ni bike, biciriritse kandi birebire bya karubone nicyuma gike gisabwa cyane nisoko; umuvuduko ntarengwa wo kuzunguruka ni 18m / s. Ibikorwa byayo byo gukora ni ibi bikurikira:
Itanura rigenda →urusyo rukora → urusyo ruri hagati → urusyo rurangiza device igikoresho cyo gukonjesha amazi bed uburiri bukonjesha → kogosha imbeho device ibikoresho byo kubara byikora → baler → ipakurura. Inzira yo kubara ibiro: diameter yo hanze Х diameter yo hanze Х0.00617 = kg / m.
