Reinforcing steel typically consists of carbon steel, which is hotrolled with deformation patterns (The ribbed profiles you see on therebar and wire), allowing for a stronger bond to the concrete. Thestee tuav thiab mesh yog tsim los ntawm cov hlau hlau thiab ua kom zoo dua steelin sib txawv steel mills thoob ntiaj teb.
Dab tsi yogtus rebar?
Tus rebar, luv rau "txhawb nqa bar" lossis "kev txhawb nqa bar", yog cov hlau lub zog uas tau siv los pab txhawb tensile lub zog ntawmcample. Raws li qhov tshwm sim, nws pab cov cuab yeej ua kom muaj cov tensile wallile, khoov, torsion, thiab shearing loads. Txij li cov araceas ntawm kev tsis muaj zog rau kev ua vaj tse, cov nyiaj them rov qab txhawb cov qauv vaj tse uas yuav txwv tsis pub muaj nyob hauv qab no.
Rebar tsis yog ib txwm pom hauv pob zeb ua qauv vim tias nws yog feem ntau faus nyob rau hauv cov qauv ua vaj tse. Nws yog ib qho yuav luag los ntawm cov hlau vim cov hlau muaj cov khoom lag luam nthuav dav zoo li cov khoom siv kub txo qis. Rebar yog feem ntau tsis du, nws yog tsim nrog tav los tiv thaiv kev cog lus hauv cov qauv ua vaj tse.
Cov rebar tau ua li cas?
Rebar yog yuav luag ib txwm ua los ntawm cov hlau, uas muaj cov khoom zoo tensile zoo tshaj plaws rau kev ua vaj tse. Qhov ntxim nyiam, nws tau ua los ntawm cov cuab yeej rov ua dua xws li cov tsheb qub, cov cuab yeej qub, thiab cov tshuab uas tau zoo nkauj, txias rau hauv daim ntawv ntawm billets, thiab tom qab ntawd khaws cia. Thaum cov billets tau npaj txhij siv rau kev ua haujlwm rebar, tab sis hauv qab no cov kab mob rebeah ib qho kev xav tau los tiv thaiv kev tawm tsam ntawm kev tawm tsam. Tus rebar yog ces sheared mus rau yam uas xav tau lenath.
Rebar ua haujlwm li cas?
Lub zog tensile ntawm cov hlau rebar ua kom lub zog compressive ntawm pob zeb ua qauv kom tsim cov qauv kom tsim cov qauv kom tsim cov qauv uas muaj cov ablend ntawm ob hom muaj zog. Qhov no txo txoj kev pheej hmoo ntawm kev pheej hmoo thiab tso cai rau cov qauv tiv thaiv kev ua kom pom zoo dua los ntawm cov khoom lag luam uas yuav ua rau muaj cov qauv ua kom tiav.
Rebar yog feem ntau nteg hauv cov qauv sib tw. Qhov no txhais tau tias cov ntu sib txawv ntawm cov rebar yog tso rau cov kev sib tw thiab cov kev tiv thaiv lub zog ntawm sab nrauv yog tias nws tuaj yeem tiv thaiv cov rebar ignar tsis plam tawm ntawm cov qauv ua vaj tse. Qee lub sij hawm rebar yog khoov ntawm qhov xaus kom txuas rau thauj tog rau nkoj nws hauv placewithin ib cov qauv ua vaj tse.
Dab tsi yog kev txhawb nqa hlau ua haujlwm?
Zoo dua cov paub tsuas yogtus rebarlossis cov hlau txhawb,siv zog kubMuaj cov kab hlau ntev hlau.Tuseese cov nyom feem ntau muaj cov jagged, tsis sib xws egroje ntawm lawv, tsim kom muaj kev tuav thiab tensantly. Lub zog hlau yog pimarly siv los txhawb cov qhob los ntawm kev siv lub zog, thiab cov tsev ua pob zeb ua kom zoo nkauj xws li phab ntsa, skvscrapers, txuas ntxiv rau cov choj, thiab lub hauv paus.
Tus rebaryog feem ntau ua rau siv ib txoj kev ua rau hluav taws xob arc ua txheej txheem ua kom cov hlau. Siv cov qauv no, scraps ntawm cov hlau ntawm txhua hom yog melted todthing thiab show stee. Nws Concoction yog tom qab ntawd nchuav rau hauv kev ua pov thiab undergoes ob peb lwm cov txheej txheem tsis muaj los ntawm daim ntawv OT asolid, ruaj ruaj steel bar.
Vim li cas cov cuab yeej cuam tshuam hlau uas tsim nyog?
Cov neeg uas tsis tau paub txog kev ua haujlwm ua haujlwm li cas tsis nkag siab vim li cas nws xav tau kev txhawb nqa thiab xav tias muaj tam sim no uas txhua yam yuav tshwm sim rau nws. Howeve, qhob nyob rau hauv thiab ntawm tus kheej muaj zog heev nro thiab txoj kev ntau dhau compression. Raws li qhov tshwm sim, qhob tsis tau lossis txav mus rau txhua tus, uas txhais tau tias nws yuav tawg thiab tawg hauv qab heasht lossis siab.
Los ntawm ntu ntxiv ntxivtxhawb hlau (rebar)Rau hauv cov qhob nws tau nce ntau ntxiv yam tsis muaj OSing AV compression li qhov tshwm sim nws qhov hnyav dua, muaj qhov hnyav nce ntxiv, ensemperatature hloov. Kev thauv yog ib qho ua rau muaj kev puas tsuaj thiab kev kho kom zoo thiab tseem qhia txog cov qauv txheej txheem uas yuav ua rau muaj teeb meem loj.
Ntau hom kev txhawb nqa hlau
Txhawm rau kom haum rau cov pob zeb ua cov tshuaj qij, muaj ntau yam diferentypes ntawm kev txhawb nqa steel rebar uas koj tuaj yeem siv. Txhua hom rebar ua hauj lwm thesame lub hom phiaj, tab sis nws yog tus txiv neej thiab tsim diferinly nyob ntawm koj cov kev xav tau.Tiv Tauj Pebf koj tsis paub tseeb tias hom ntawm kev txhawb nqa hlau yog txoj cai rau koj.
►Prestressing Hlau Bars
Prestressing steel kab yog ntau dua li tuab, cov xov hlau nyuaj tshaj li tuav. Qhov tseem ceeb, hom kev txhawb nqa kev txhawb nqa obliv muaj ob mus rau xya cov hlau roj carbon hlau lossis pas nrig welded ua ke rau hauv ib qho nyias, zoo, khoom bar. Presressing Stee! Cov tuav tau muaj feem ntau flexibtly thiab kev xav tsis tau tab sis tsis tsim nyog qhov muaj zog tshaj ntawm rebar.
►Kub Daus Deformed Hlau Bars
Hotroled deformed stee! Cov tuav hluav taws xob yog cov popuar feem ntau thiab hom kev txhawb nqa stelin kev tsim kho kev tsim kho. Theyre cov kab uas koj ib txwm pom ntawm ib qho Sie thiab tau siv nyob rau hauv cov hauv paus, WSS, thiab lwm yam kev lom zem, hotioled. deiommed steel tuav kuj muaj ribbed edoes vou nus rebar.
►Mild Hlau Plawv Hlau
Tsis zoo li nws muab nws cov npoo hlau uas muaj Ribbed cov npoo, cov pob zeb tawv dub muaj zog yog cov hom rebar tab sis muaj kev tsim tawm ntau dua los tsim.
►Txias ua haujlwm steel tuav
Cov pob coldworked cov hlau yog zoo heev rau kev tiv thaiv cov hlau domormed itormed steel kab, muaj ib qho kev zam. A a a a anouroled ovroled, cov hlau tuav tau yauv thib ob, lub sijhawm ua haujlwm txias, thaum muaj zog ua haujlwm me ntsis thiab cov tub rog qis dua li lawv cov khoom siv kub.
