Pamusoro peRebar
Iri rakaremara simbi bhaa yakajairika simbi yekusimbisa bar / inoshandiswa mune yakasimbiswa kongiri uye yakasimbiswa masonry zvimiro. Inoumbwa kubva kusimbi yakapfava uye inopiwa mbabvu kuitira zviri nani frictional adhesion kune kongiri. Deformation yembabvu nekuda kwebasa rembabvu, uye kongiri vane kugona kukuru kwekubatana, izvo zvinogona kutsungirira zvirinani masimba ekunze. Iyo yakaremara simbi simbi isimbi, inokwenenzverwa bani inosimbisa simbi, uye inogona kushandiswa zvakare kune meshes esimbi. Chimiro chembabvu dzakachinjika ndeye spiral, herringbone, crescent-shaped three. Iyo dhayamita yezita rekuremara yakasimbiswa simbi bar inoenderana nezita rekuti dhayamita yedenderedzwa bar yeakaenzana muchinjiko-chikamu. Kongiri yakasimbiswa mune huru tensile stress.

Mhando dzeRebars
Zvichienderana nerudzi rwezvinhu zvakashandiswa mukugadzira rebar, marudzi akasiyana emareba ari
l 1. European Rebar
European rebar yakagadzirwa nemanganese, izvo zvinoita kuti vakotama nyore. Hadzina kukodzera kushandiswa munzvimbo dzinowanzoita mamiriro ekunze akanyanya kana mamiriro enzvimbo, sekudengenyeka kwenyika, madutu, kana chamupupuri. Mutengo weiyi rebar wakaderera.
l 2. Carbon Steel Rebar
Sezvinomiririra zita, inogadzirwa nekabhoni simbi uye inowanzo zivikanwa seBlack Bar nekuda kwekabhoni ruvara. Mhedzisiro huru yeiyi rebar ndeyekuti inoshatisa, izvo zvinokanganisa kongiri uye chimiro. Iyo tensile simba reshiyo yakasanganiswa nehukoshi inoita dema rebar imwe yeakanakisa sarudzo.
l 3. Epoxy-Coated Rebar
Epoxy-coated rebar iblack rebar ine epoxy jasi. Iine simba rakafanana rekusimba, asi inopeta 70 kusvika ku1,700 kakawanda inoshingirira mukuora. Nekudaro, iyo epoxy coating yakatetepa zvakanyanya. Iyo yakakura kukuvadzwa kwejasi, iyo isingadzivirirwe nekuora.
l 4. Galvanized Rebar
Galvanized rebar inongopeta makumi mana chete inoshingirira mukuora pane dema rebar, asi zvakanyanya kuoma kukuvadza kuvharwa kwegalvanized rebar. Mune izvo, ine kukosha kwakawanda kupfuura epoxy-yakavharwa rebar. Zvisinei, inenge 40% inodhura kupfuura epoxy-coated rebar.
l 5. Girazi-Fiber-Reinforced-Polymer (GFRP)
GFRP inoumbwa nekabhoni fiber. Sezvo inogadzirwa ne fiber, kukotama hakubvumirwi. Iyo inoshingirira zvakanyanya kune corrosion uye inodhura kana ichienzaniswa nemamwe mareba.
l 6. Stainless Steel Rebar
Stainless simbi rebar ndiyo inodhura zvakanyanya yekusimbisa bhaa inowanikwa, ingangoita kasere mutengo we epoxy-yakavharwa rebar. Iyo zvakare ndiyo yakanakisa rebar inowanikwa kune akawanda mapurojekiti. Nekudaro, kushandisa simbi isina tsvina mune zvese asi iyo yakanyanya kusarudzika yemamiriro ezvinhu kunowanzo kuwandisa. Asi, kune avo vane chikonzero chekuishandisa, Stainless simbi rebar 1,500 times more resisting to corrosion than black bar; inodzivirira kukuvadzwa kupfuura chero imwe yeimwe corrosive-resistant kana corrosive-proof mhando kana rebar; uye inogona kukotama mumunda.
