Kev tsim cov hlau stainless grating hauv cov cement cog yuav tsum ua raws li cov hauv qab no:
1. Qhov sib nrug ntawm cov khoom thauj khoom tiaj tus hlau thiab qhov sib nrug ntawm tus ntoo khaub lig tuav ntawm cov hlau grating yog txiav txim siab raws li tus qauv tsim. Raws li kev lag luam platform, qhov sib nrug ntawm cov khoom thauj tiaj tus hlau tsis ntau dua 40mm; Thaum kawg ntawm lub loaded ca steel, siv tib lub specification raws li lub loaded ca steel. Hlau rau edging; Nyob rau hauv tshwj xeeb zaus, siv profiled steel los yog ncaj qha siv rib phaj rau edging, tab sis lub cross-sectional cheeb tsam ntawm lub edging phaj yuav tsum tsis txhob tsawg tshaj li qhov cross-sectional cheeb tsam ntawm lub loaded ca steel.
2. Lub edging ntawm cov hlau grating txais ib leeg-ib sab fillet vuam nrog lub vuam qhov siab tsis tsawg tshaj li lub thickness ntawm lub loaded ca steel, thiab qhov ntev ntawm vuam seam yog tsis tsawg tshaj li 4 npaug ntawm lub thickness ntawm loaded ca steel. ; Thaum lub edging phaj tsis dais lub load, lub sij hawm tso cai Plaub load ca steels yog welded ntawm ib qhov chaw, tab sis qhov sib nrug tsis ntau tshaj 180mm; Thaum lub edging phaj yog nyob rau hauv load, lub sij hawm vuam tsis pub, thiab nws yuav tsum tau welded tag nrho.
3. Lub ntug phaj ntawm lub stair tread yuav tsum tau welded tag nrho ntawm ib sab, thiab cov edging phaj nyob rau hauv tib txoj kev raws li lub load ca steel yuav tsum tau welded nrog txhua crossbar. Yog hais tias lub stair tread muaj ib tug pem hauv ntej ntug edging tus neeg zov, nws yuav tsum khiav mus rau tag nrho cov kauj ruam.
4. Cov incisions thiab qhib nyob rau hauv lub steel grating yog sib npaug zos rau los yog ntau tshaj 180mm, thiab yuav tsum tau kho nrog ntug wrapping.
5. Feem ntau muaj 3 hom steel grating load tiaj tus steel, thiab lub load tiaj tiaj steel tuaj yeem muaj cov hniav zoo tuaj yeem ua rau kom muaj zog tiv thaiv ntawm cov hlau grating, tsis pub tsawg tshaj 5 hniav ib 100 hli.
