Pfupiso yeRebar
Iyi simbi yakakanganisika isimbi yakajairika yekusimbisa/ inoshandiswa mukongiri yakasimbiswa uye zvivakwa zvematombo akasimbiswa. Inoumbwa nesimbi yakapfava uye inopiwa mbabvu kuti inamatire zviri nani kongiri. Kushanduka kwembabvu nekuda kwebasa rembabvu, uye kongiri zvine kugona kukuru kwekubatana, izvo zvinogona kumira zviri nani masimba ekunze. Simbi yakakanganisika itsvimbo yesimbi, simbi inosunganidzwa, uye inogona kushandiswawo kune meshes yesimbi. Chimiro chembabvu dzakachinjika ispiral, herringbone, crescent-shaped three. Dhayamita yesimbi yakakanganisika inoenderana nedhayamita yesimbi yakatenderera yechikamu chakaenzana. Kongiri yakasimbiswa mukumanikidzwa kukuru.

Mhando dzeRebars
Zvichienderana nerudzi rwezvinhu zvinoshandiswa pakugadzira rebar, mhando dzakasiyana dzerebar dzinowanikwa.
l 1. European Rebar
European rebar yakagadzirwa nemanganese, iyo inoita kuti dzikotame zviri nyore. Hadzina kukodzera kushandiswa munzvimbo dzinonyanya kukanganiswa nemamiriro ekunze akaipisisa kana migumisiro ye geological, senge kudengenyeka kwenyika, madutu, kana madutu. Mutengo we rebar iyi wakaderera.
l 2. Kabhoni Simbi Rebar
Sezvinomiririra zita racho, yakagadzirwa nesimbi yekabhoni uye inozivikanwa seBlack Bar nekuda kweruvara rwekabhoni. Dambudziko guru re rebar iyi nderekuti inoora, izvo zvinokanganisa kongiri nechimiro. Chiyero chesimba rekudhonza pamwe chete nehukuru zvinoita kuti black rebar ive imwe yesarudzo dzakanakisisa.
l 3. Rebar Yakaputirwa neEpoxy
Rebar ine epoxy-coated iblack rebar ine epoxy coat. Ine simba rakafanana rekudhonza, asi inodzivirira ngura ka70 kusvika 1,700. Zvisinei, epoxy coat inonyorova zvikuru. Kana coat ichikuvara zvakanyanya, inodzivirira ngura zvishoma.
l 4. Ganda resimbi rakabatidzwa
Ganda resimbi rinodzivirirwa kubva mukuora kakapetwa makumi mana chete kupfuura dema rebar, asi zvakaoma kukuvadza kuputira kweganda resimbi. Panyaya iyi, rine kukosha kukuru kupfuura epoxy-coated rebar. Zvisinei, rinodhura ne40% kupfuura epoxy-coated rebar.
l 5. Girazi-Fiber-Reinforced-Polymer (GFRP)
GFRP inogadzirwa nefayibha yekabhoni. Sezvo yakagadzirwa nefayibha, kukotama hakubvumirwi. Inodzivirira ngura zvakanyanya uye inodhura kana ichienzaniswa nedzimwe simbi.
l 6. Simbi Isina Kusimba
Stainless steel rebar ndiyo resinsor bar inodhura zvikuru iripo, mutengo wayo wakapetwa kasere kupfuura epoxy-coated rebar. Ndiyo zvakare rebar yakanakisa inowanikwa kumapurojekiti mazhinji. Zvisinei, kushandisa simbi isina ngura mumamiriro ese ezvinhu akasiyana kazhinji kunonyanya kudhura. Asi, kune avo vane chikonzero chekuishandisa, rebar yesimbi isina ngura inodzivirirwa nengura ka1,500 kupfuura black bar; inodzivirira kukuvara kupfuura mamwe marudzi e rebar kana rebar inodzivirira ngura; uye inogona kukotama mumunda.
