Incamake ya Rebar
Iki cyuma cyahinduwe nicyuma gisanzwe gishimangira ibyuma / bikoreshwa muri beto yubakishijwe ibyuma byubakwa. Ikozwe mubyuma byoroheje kandi ihabwa imbavu kugirango ifatanye neza na beto. Guhindura imbavu bitewe nuruhare rwimbavu, na beto bifite ubushobozi bunini bwo guhuza, bushobora guhangana neza nimbaraga zo hanze. Icyuma cyahinduwe ni inkoni yicyuma, icyuma gishobora gusudira cyuma gishimangira ibyuma, kandi gishobora gukoreshwa kimwe nicyuma. Imiterere y'urubavu ruhindagurika ni umuzenguruko, herringbone, ukwezi gutatu. Diameter ya nominal yumurongo wibyuma byahinduwe byahujwe na diametre nominal yumuzingi wizunguruka zingana. Ibyuma bishimangirwa mubitekerezo nyamukuru.

Ubwoko bwa Rebars
Ukurikije ubwoko bwibikoresho byakoreshejwe mugukora rebar, ubwoko butandukanye bwa rears ni
l 1. Rebar yu Burayi
Rebar yu Burayi ikozwe muri manganese, ituma byunama byoroshye. Ntibikwiriye gukoreshwa ahantu hakunze kwibasirwa nikirere gikabije cyangwa ingaruka za geologiya, nka nyamugigima, inkubi y'umuyaga, cyangwa tornado. Igiciro cyiyi rebar ni gito.
l 2. Icyuma Cyuma Cyuma
Nkuko izina ryerekana, rigizwe nicyuma cya karubone kandi kizwi cyane nka Black Bar kubera ibara rya karubone. Ingaruka nyamukuru yiyi rebar nuko yangirika, bigira ingaruka mbi kuri beto nuburyo. Ikigereranyo cyingufu zingana hamwe nagaciro bituma umukara rebar imwe mumahitamo meza.
l 3. Epoxy-Coated Rebar
Epoxy-isize rebar ni umukara rebar hamwe na koti ya epoxy. Ifite imbaraga zingana, ariko irusha inshuro 70 kugeza 1.700 kwihanganira ruswa. Nyamara, epoxy coating iroroshye cyane. Nibyinshi byangiritse kuri coating, ntibishobora kwihanganira ruswa.
4. Guhindura Rebar
Imiyoboro ya Galvanised irwanya inshuro mirongo ine gusa kwihanganira kwangirika kuruta umukara wirabura, ariko biragoye kwangiza igifuniko cya rezo. Muri urwo rwego, ifite agaciro karenze epoxy-coated rebar. Ariko, ihenze hafi 40% kuruta epoxy-coated rebar.
l 5. Ikirahure-Fibre-Yongerewe imbaraga-Polymer (GFRP)
GFRP igizwe na fibre karubone. Nkuko bigizwe na fibre, kunama ntibyemewe. Irwanya cyane ruswa kandi ihenze mugihe ugereranije nizindi rears.
l 6. Icyuma Cyuma
Icyuma kitagira umuyonga nicyuma gihenze cyane cyo gushimangira kiboneka, hafi inshuro umunani igiciro cya epoxy-coated rebar. Nubundi rebar nziza iboneka kumishinga myinshi. Ariko, gukoresha ibyuma bitagira umwanda muri byose ariko ibintu bidasanzwe mubihe akenshi birenze urugero. Ariko, kubafite impamvu yo kuyikoresha, ibyuma bidafite ingese byikubye inshuro 1.500 birwanya ruswa kuruta ibara ry'umukara; irwanya kwangirika kurenza iyindi moko yose irwanya ruswa cyangwa irwanya ruswa cyangwa rebar; kandi irashobora kugororwa mu murima.
