Rebar, yomwe nthawi zambiri imatchedwachogwirira ntchito, imagwira ntchito yofunika kwambiri pa ntchito yomanga, kupereka mphamvu yokoka yofunikira pothandizira nyumba za konkire. Mtundu wa chitsulo chomwe chimasankhidwa pa ntchito nthawi zambiri chimadalira mphamvu yake komanso momwe chimagwiritsidwira ntchito, kotero mainjiniya ndi omanga ayenera kudziwa zinthu izi.
Pali mitundu yambiri ya rebar, iliyonse yopangidwira ntchito inayake. Mitundu yodziwika kwambiri ndi iyi:
1. Chitsulo chofewa cholimba(Kalasi 40): Mtundu uwu uli ndi mphamvu yotulutsa ya 40,000 psi ndipo umagwiritsidwa ntchito kwambiri m'mapulojekiti okhala anthu monga njira zoyendera ndi misewu. Kusinthasintha kwake kumapangitsa kuti ikhale yosavuta kupindika ndi kupanga.
2. Chitsulo champhamvu kwambiri(Giredi 60): Chitsulo ichi chili ndi mphamvu yotulutsa ya 60,000 psi ndipo ndi choyenera kugwiritsidwa ntchito m'mabizinesi ndi m'mafakitale, kuphatikizapo nyumba zazitali ndi Milatho. Kuwonjezeka kwa mphamvu yake kungachepetse kugwiritsa ntchito zipangizo popanda kusokoneza umphumphu wa nyumbayo.
3. Rebar yokhala ndi epoxy-coated: Mtundu uwu umakutidwa ndi epoxy kuti usawonongeke, zomwe zimapangitsa kuti ukhale wabwino kwambiri pa nyumba zomwe zili pamalo ovuta, monga Marine applications kapena malo omwe ali ndi chinyezi chambiri.
4. Chitsulo chosapanga dzimbiri: Chitsulo chosapanga dzimbiri cholimba chimadziwika chifukwa cha kukana dzimbiri kwambiri ndipo chimagwiritsidwa ntchito m'malo omwe amakhudzidwa ndi dzimbiri kwambiri monga zomera za mankhwala ndi nyumba za m'mphepete mwa nyanja.
Mlingo wa mphamvu ndi kufunika kwake:
Mphamvu ya rebar ndiyo chinthu chofunikira kwambiri kuti chidziwike mphamvu yake yonyamula katundu. Magiredi apamwamba, monga giredi 75 kapena 80, amapereka mphamvu yokwera kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito molemera. Kusankha giredi ya mphamvu kumakhudza mwachindunji kapangidwe ndi chitetezo cha nyumbayo chifukwa kumakhudza kuchuluka kwa katundu womwe zitsulo zachitsulo zimatha kunyamula.
Pomaliza, kumvetsetsa mitundu yosiyanasiyana ya rebar ndi mphamvu zake zofanana ndikofunikira kwambiri posankha zipangizo zoyenera pa ntchito iliyonse yomanga. Poganizira momwe zinthu zilili komanso momwe zinthu zilili, omanga nyumba amatha kuwonetsetsa kuti nyumba zawo zili ndi moyo wautali komanso chitetezo.
