Kev tshuaj xyuas qhov zoo
Yuav tsum tsis txhob pom cov kab nrib pleb, folds, folds, delamination thiab caws pliav ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab steel. Cov teeb meem no yuav tsum raug tshem tawm tag nrho, qhov tob tshem tawm yuav tsum tsis pub tshaj 10% ntawm phab ntsa thickness, thiab qhov tseeb phab ntsa thickness ntawm qhov chaw ntxuav yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus tso cai phab ntsa thickness, thiab qhov chaw tshem tawm yuav tsum muaj ib tug du kev hloov.
Qhov ncaj qhov tob ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab steel yuav tsum ua raws li cov cai hauv qab no: rau cov kav dej kub-dov hlau, nws yuav tsum tsis pub tshaj 5% ntawm phab ntsa thickness thiab yuav tsum tsis pub tshaj 0.4 hli; rau cov kav dej kub-expanded steel, nws yuav tsum tsis pub tshaj 0.5 hli; rau txias-dov (kos) steel kav, nws yuav tsum tsis txhob tshaj phab ntsa thickness 4% ntawm thickness thiab tsis pub tshaj 0.2 hli. Lwm qhov kev tsis zoo hauv zos tuaj yeem tshwm sim uas qhov tob tsis tshaj qhov sib txawv hauv qab phab ntsa thickness.
