Isishwankathelo seRebar
Le bar yentsimbi ekhubazekileyo yintsimbi eqhelekileyo yokuqinisa ibha / esetyenziswa kwikhonkrithi eyomeleziweyo kunye nezakhiwo eziqinisiweyo ze-masonry.Yenziwe ngentsimbi epholileyo kwaye inikwe iimbambo zokubambelela okungcono kwi-frictional kwikhonkrithi.Ukuguqulwa kweembambo ngenxa yendima yeembambo, kunye nekhonkrithi inamandla amakhulu okudibanisa, enokumelana ngcono namandla angaphandle.Intsimbi yentsimbi egogekileyo yintonga yentsimbi, intsimbi edityanisiweyo edityanisiweyo, kwaye inokusetyenziswa nakwiminatha yentsimbi.Imilo yeembambo ezinqamlezileyo zi-spiral, herringbone, i-crescent-shaped three.I-dameter ye-deformed ye-deformed reinforced bar ihambelana nobubanzi obubizwa ngokuba yi-circular bar ye-cross-section elinganayo.Ikhonkrithi eyomeleziweyo kuxinzelelo oluphambili lwe-tensile.

Iintlobo zeeRebar
Ngokuxhomekeke kuhlobo lwemathiriyeli esetyenzisiweyo kwimveliso ye-rebar, iintlobo ezahlukeneyo zee-rebar
l 1. I-European Rebar
I-rebar yaseYurophu yenziwe ngemanganese, eyenza ukuba igobe ngokulula.Ayikulungelanga ukusetyenziswa kwiindawo eziqhelene neemeko zemozulu ezimbi kakhulu okanye iziphumo zejoloji, ezifana neenyikima, iinkanyamba, okanye iinkanyamba.Iindleko zale rebar ziphantsi.
l 2. Carbon Steel Rebar
Njengoko igama limele, yenziwe ngentsimbi yekhabhoni kwaye yaziwa ngokuba yiBlack Bar ngenxa yombala wekhabhoni.I-drawback ephambili yale rebar kukuba i-corrodes, echaphazela kakubi ikhonkrithi kunye nesakhiwo.Umlinganiselo wamandla obunzima obudityaniswa nexabiso lenza i-rebar emnyama ibe lolona khetho lubalaseleyo.
l 3. I-Epoxy-Coated Rebar
I-epoxy-coated rebar yirebar emnyama enedyasi ye-epoxy.Inamandla afanayo okuqina, kodwa iyakwazi ukumelana namaxesha angama-70 ukuya kwi-1,700 ngakumbi kumhlwa.Nangona kunjalo, i-epoxy coating ithambile kakhulu.Umonakalo omkhulu kwi-coating, iyancipha ukumelana nokubola.
l 4. I-Rebar enezingxobo
Irebar eyenziwe ngegalvanized ixhathisa ngokuphindwe kamashumi amane kumhlwa kunerebar emnyama, kodwa kunzima kakhulu ukonakalisa isigqubuthelo serebar eyenziwe ngamagalvanized.Ngaloo ndlela, inexabiso elingaphezulu kune-epoxy-coated rebar.Nangona kunjalo, ixabisa malunga ne-40% ngaphezulu kune-epoxy-coated rebar.
l 5. I-Glass-Fiber-Reinforced-Polymer (GFRP)
I-GFRP yenziwe ngefayibha yekhabhoni.Njengoko yenziwe ngefayibha, ukugoba akuvumelekanga.Iyakwazi ukumelana nokudleka kwaye iyabiza xa ithelekiswa nezinye iibar.
l 6. I-Stainless Steel Rebar
I-rebar yensimbi engenastainless yeyona bar yokuqinisa ebiza kakhulu ekhoyo, malunga namaxesha asibhozo exabiso le-epoxy-coated rebar.Ikwayeyona rebar ilungileyo ekhoyo kwiiprojekthi ezininzi.Nangona kunjalo, ukusebenzisa insimbi engenasici kuzo zonke kodwa ezona meko zikhethekileyo zihlala zigqithise.Kodwa, kwabo banesizathu sokuyisebenzisa, i-stainless steel rebar iphinda-phinda amaxesha angama-1,500 axhathisa ukubola kune-black bar;ixhathisa ngakumbi kumonakalo kunazo naziphi na ezinye iintlobo ezikwaziyo ukudleka okanye ubungqina obunokutshabalalisa okanye isithinteli;kwaye inokugotywa entsimini.
