I-Rebar, evame ukubizwa ngokuthii-rebar, idlala indima ebalulekile ekwakheni, ihlinzeka ngamandla okunamathela adingekayo ukusekela izakhiwo zekhonkrithi. Uhlobo lwensimbi olukhethwayo lwephrojekthi luvame ukuncika ezingeni layo lamandla kanye nokusetshenziswa kwayo okuthile, ngakho onjiniyela nabakhi kumele baqaphele lezi zici.
Kunezinhlobo eziningi ze-rebar, ngayinye eyenzelwe uhlelo oluthile. Izinhlobo ezivame kakhulu zifaka:
1. I-rebar yensimbi ethambile(Isigaba 40): Lolu hlobo lunamandla okukhiqiza angu-40,000 psi futhi luvame ukusetshenziswa kumaphrojekthi okuhlala njengemigwaqo yezimoto kanye nemigwaqo yabahamba ngezinyawo. Ukuguquguquka kwalo kwenza kube lula ukugoba nokwakheka.
2. Insimbi enamandla aphezulu(Ibanga 60): Le nsimbi inamandla okukhiqiza angu-60,000 psi futhi ifanele ukusetshenziswa kwezentengiselwano nezimboni, okuhlanganisa izakhiwo ezinde namabhuloho. Ukwanda kwamandla ayo kunganciphisa ukusetshenziswa kwezinto ngaphandle kokuthinta ubuqotho besakhiwo.
3. I-rebar ene-epoxy-coated: Lolu hlobo lumbozwe nge-epoxy ukuze lumelane nokugqwala, okwenza lube luhle kakhulu ezakhiweni ezivezwe ezindaweni ezinzima, njengezicelo zasemanzini noma izindawo ezinomswakama ophezulu.
4. Ibha yensimbi engagqwali: I-rebar yensimbi engagqwali yaziwa ngokumelana kwayo nokugqwala okuphezulu futhi isetshenziswa ezindaweni ezigqwala kakhulu njengezitshalo zamakhemikhali nezakhiwo zasogwini.
Izinga lokuqina kanye nokubaluleka kwalo:
Izinga lamandla le-rebar liyisici esibalulekile sokunquma amandla ayo okuthwala. Izinga eliphezulu, njengebanga 75 noma 80, linikeza amandla aphezulu okudonseka, okwenza lifanelekele ukusetshenziswa kwemisebenzi enzima. Ukukhetha izinga lamandla kuthinta ngqo ukwakheka nokuphepha kwesakhiwo ngoba kuthinta inani lomthwalo ongasethwa yizingodo zensimbi.
Ekuphetheni, ukuqonda izinhlobo ezahlukene ze-rebar kanye namazinga azo ahambisanayo amandla kubalulekile ekukhetheni izinto ezifanele kunoma yimuphi umsebenzi wokwakha. Ngokucabangela ukusetshenziswa okuthile kanye nezimo zemvelo, abakhi bangaqinisekisa impilo yesevisi kanye nokuphepha kwezakhiwo zabo.
