Qhov rooj hluav taws kub yog ib lub qhov rooj hluav taws, uas yog lub qhov rooj ua los ntawm cov khoom siv hlau. Nws kuj tau nruab nrog lwm cov khoom siv hluav taws kub, uas tuaj yeem nruab thiab siv tom qab sib dhos.
① Nebefore Txhim kho lub qhov rooj hluav taws kub steel, thov saib seb puas muaj qhov rooj puas lossis tsis yog, thiab tom qab ntawd thiab tom qab ntawd ua kom muaj kev nyab xeeb. Tseem them nyiaj rau kev siv tiv thaiv kev tiv thaiv ntawm ob sab ntawm lub qhov rooj kom tsis txhob raug puas los yog khawb, cuam tshuam rau qhov zoo ntawm lub qhov rooj hluav taws.
② Cov khoom ntawm cov khoom yuav tsum yog tus thiab huv thiab huv tsis pom kev puas tsuaj los yog txhav. Kev siv vuam yuav tsum ua kom ruaj, thiab cov pob qij txha sib zog yuav tsum tau faib cuavy, thiab yuav tsum tsis muaj cov cim ntawm kev ua txhaum cai, hlawv-dhau, thiab ploj lawm soldering.
Qhov rooj hluav taws xob tsis tuaj yeem hnov cov rooj tua hluav taws kub tsis tau hnov thaum lub qhov rooj hluav taws kub uas tau muab tso rau weld tau. Cov pob qij txha solder yog qhov sib npaug zoo, thiab cov tsos yog tsuag yooj yim. Yuav tsum muaj cov cim kos npe ntawm txoj haujlwm xaiv, thiab cov tuab ntawm lub qhov rooj lub qhov rooj yuav tsum muaj ntau dua los yog sib npaug ntawm cov nplooj rooj lub qhov rooj hauv cov qauv duab. Qhov dav ntawm sab phab ntsa ntawm lub qhov rooj thav duab yuav tsum tsawg dua los yog sib npaug ntawm cov iav hluav taws xob yuav tsum muaj ntau dua los yog sib npaug ntawm cov iav fireness hauv cov qauv pom kev.
Txhawm rau xyuas kom muaj kev ua yeeb yam ntawm lub qhov rooj hluav taws kub steel, nws yog qhov tsim nyog kom muaj kev tiv thaiv kom raug, thiab nws yuav tsum tau muab kev thauj khoom. Nqa ib zaug ntxiv, ua tib zoo mloog rau theem thiab tawm kom huv si thaum tso quav, yog tias muaj cov teeb meem tiv thaiv, yog tias muaj teeb meem dab tsi, daws lawv sai li sai tau. Yuav tsum tau ua ke facade yuav tsum muab tso rau zoo, kaw lub qhov rooj qhov rooj kom tsis txhob khob lub qhov rooj ntawm sab nraud ntawm lub sijhawm kawg. Tsis txhob puas tsuaj cov yeeb yaj kiab tiv thaiv thaum thauj mus los.
