1. Rebar tawb fabrication yuav tsum tau nqa tawm nyob rau hauv ib tug hardened rebar cheeb tsam kom zoo binding thiab vuam ntawm cov txheej txheem rebars.
2. Cov pob qij txha ntawm cov hlua txuas ntxiv yuav tsum yog ob npaug -sab welded, nrog lub ceg ntev ntev dua lossis sib npaug li 5 npaug ntawm txoj kab uas hla ntawm lub rebar kom muaj kev sib txuas zoo.
3. Rebar tawb pob qij txha yuav tsum tau staggered, thiab tus naj npawb ntawm cov pob qij txha ntawm tib tus ntoo khaub lig-section yuav tsum tsis txhob ntau tshaj 50% ntawm tag nrho cov xov tooj kom nce kev ruaj ntseg.
4. Tom qab lub rebar tawb yog fabricated, nws yuav tsum tau ntsuas nws nruj thiab stability. Yog tias tsim nyog, tus naj npawb ntawm cov kev txhawb zog ntxiv yuav tsum tau nce ntxiv, thiab cov hlua hla yuav tsum tau welded rau hauv lub stirrups kom muaj zog txaus thiab ruaj khov thaum lub sij hawm thauj mus los, hoisting, thiab pob zeb pouring, tiv thaiv loosening, displacement, los yog deformation.
5. Thaum lub sij hawm vuam, cov txheej electrode decomposes thiab melts, tsim cov roj thiab slag, uas tiv thaiv qhov chaw vuam thiab pab deoxidize thiab purify cov hlau molten. Raws li cov hluav taws xob arc txav, lub workpiece thiab weld core txuas ntxiv yaj, tsim lub pas dej tshiab molten. Tus thawj molten pas dej ua ke txias thiab solidifies thaum lub arc txav mus, tsim ib tug weld, yog li txuas ob workpieces rau hauv ib chav tsev.
Nco tseg:
1. Rau cov txheej txheem luv luv, lub tawb nqa khoom tuaj yeem tsim los ua ib qho chaw rau kev ua tiav hoisting hauv ib qho mus.
2. Thaum fabricating lub reinforcing tawb, yuav tsum tau siv cov jigs tsim nyog, thiab qhov sib nrug thiab ncaj ntawm lub reinforcing tuav yuav tsum nruj me ntsis tswj.
3. Thaum lap welding lub ntsiab reinforcing tuav nyob rau hauv ib tug segmented reinforcing tawb, lub reinforcing tuav yuav tsum tau ua ntej -khoov, kom ntseeg tau tias tus naj npawb ntawm cov pob qij txha ntawm tib seem tsis pub tshaj 50% ntawm tag nrho cov tooj ntawm lub ntsiab reinforcing tuav, thiab qhov kev ncua deb ntawm ob pob qij txha yog tsis tsawg tshaj li 500 hli. Main reinforcing bar welding yuav tsum yog ib leeg -sab, nrog ib tug weld ntev tsis tsawg tshaj li 10d.
4. Stirrups yuav tsum tau muab ob npaug rau-sided welded, nrog ib tug weld ntev tsis tsawg tshaj li 5 npaug ntawm stirrup txoj kab uas hla, thiab tsuas yuav overlapped vertically, tsis radially. Qhov kev sib txuas ntawm qhov sib zog sib zog thiab cov hlua tseem ceeb yuav tsum tau welded.
5. Thaum lub sij hawm kev thauj mus los, lub tawb nqa khoom yuav tsum tau ntxiv dag zog los tiv thaiv dov thiab kom nws cov duab tsis puas.
6. Tom qab lub pob zeb txhawb nqa tau muab tso rau hauv qhov chaw, qhov chaw ceev yuav tsum tau tswj kom tsis txhob khawb lub qhov phab ntsa.
