Square thiab rectangular txias tsim hollow steel, hu ua square yeeb nkab thiab cov yeeb nkab duab plaub, code F thiab J feem.
1. Qhov tso cai sib txawv ntawm cov phab ntsa thickness ntawm cov yeeb nkab square square yuav tsum tsis txhob ntau tshaj los yog rho tawm 10% ntawm nominal phab ntsa thickness thaum phab ntsa thickness tsawg tshaj li 10 hli, thiab ntxiv los yog rho tawm 8% ntawm phab ntsa thickness thaum phab ntsa thickness. yog ntau tshaj 10mm, tsuas yog cov phab ntsa thickness ntawm lub ces kaum thiab weld cheeb tsam.
2. Lub sij hawm xa khoom ntev ntawm lub raj square yog 4000mm-12000mm, feem ntau 6000mm thiab 12000mm.Cov yeeb nkab square yog tso cai kom xa tsis pub tsawg dua 2000mm luv thiab cov khoom tsis ruaj khov, tuaj yeem xa tuaj rau hauv daim ntawv ntawm cov yeeb nkab sib txuas, tab sis cov neeg siv khoom yuav tsum tau siv thaum cov yeeb nkab txuas yuav tsum raug tshem tawm.Qhov hnyav ntawm qhov loj me thiab cov khoom tsis ruaj khov yuav tsum tsis pub tshaj 5% ntawm tag nrho cov khoom xa tuaj, rau qhov theoretical hnyav ntawm ntau tshaj 20kg / m square yeeb nkab yuav tsum tsis pub tshaj 10% ntawm tag nrho cov khoom xa tuaj.
3. Qhov kev khoov ntawm lub raj square yuav tsum tsis txhob ntau tshaj 2 hli ib 'meter', thiab tag nrho cov dabtsi yog khoov degree yuav tsum tsis txhob ntau tshaj 0.2% ntawm tag nrho cov ntev.
