Steel gratings feem ntau ua tiav rau hauv cov duab ntawm ntau qhov ntau thiab tsawg raws li cov neeg siv khoom xav tau. Qhov sib nrug ntawm cov khoom thauj tiaj tus hlau thiab qhov sib nrug ntawm cov ntoo khaub lig tuaj yeem txiav txim siab los ntawm tus neeg muag khoom thiab tus neeg yuav khoom raws li kev tsim qauv. Rau kev lag luam platforms, nws raug pom zoo tias qhov kev ncua deb ntawm cov khoom tiaj tus yuav tsum tsis txhob siab tshaj 40mm, thiab qhov kev ncua deb ntawm tus ntoo khaub lig tuav yuav tsum tsis txhob ntau tshaj 165mm. Qhov vuam ntawm cov hlau grating yog qhov zoo dua los ntawm kev kub siab welding, lossis arc vuam. Nyob rau ntawm txhua qhov kev sib tshuam ntawm cov khoom thauj tiaj tus hlau thiab cov hlaws bar, nws yuav tsum tau kho los ntawm vuam, riveting los yog siab locking.
Thaum kawg ntawm kev thauj khoom tiaj tus hlau, lub tiaj tus hlau ntawm tib lub ntsiab lus raws li cov khoom thauj tiaj tus steel yuav tsum tau siv rau hemming. Nyob rau lub sijhawm tshwj xeeb, cov hlau ntu tuaj yeem siv tau lossis cov npoo phaj tuaj yeem muab qhwv ncaj qha, tab sis tus ntoo khaub lig- ntu ntu ntawm cov phaj qhwv yuav tsum tsis txhob me dua li ntawm cov hlau thauj khoom. Lub edging txais ib qho -ib sab fillet welding nrog lub vuam qhov siab tsis tsawg tshaj li lub thickness ntawm lub loaded ca steel, thiab qhov ntev ntawm lub vuam yuav tsum tsis txhob tsawg tshaj li 4 npaug ntawm lub thickness ntawm loaded ca steel.
Nyob rau hauv rooj plaub uas lub edging phaj tsis nqa lub load, nws raug tso cai rau weld 4 loaded ca steels ntawm ib qhov chaw, tab sis qhov deb yuav tsum tsis txhob ntau tshaj 180mm. Thaum lub phaj edging nyob rau hauv load, lub sij hawm vuam tsis pub thiab yuav tsum tau welded tag nrho. Qhov kawg daim hlau ntawm stair treads yuav tsum tau welded tag nrho ntawm ib sab. Lub edging phaj nyob rau hauv tib txoj kev raws li lub load ca steel yuav tsum tau welded nrog txhua tus ntoo khaub lig bar.
Steel grating series 1 welds ib txhua tsib; series 2 welds ib txhua plaub; series 3 welds ib txhua peb. Lub tiaj tus hlau nrog txawv specifications los ntawm cov hlau grating tiaj tus hlau yuav siv tau rau edging, los yog lub edging nrog lub kaum sab xis steel, channel steel, square raj, thiab lwm yam. 3mm, thiab qhov ntev ntawm qhov vuam yog 20mm.
Lub edging txais yuav ib leeg -ib sab fillet welding nrog ib tug vuam qhov siab tsis tsawg tshaj li lub thickness ntawm cov kabmob tiaj tus hlau, thiab qhov ntev ntawm cov vuam yuav tsum tsis pub tsawg tshaj 4 npaug ntawm cov thickness ntawm cov kabmob ca steel.
Nyob rau hauv rooj plaub uas lub edging phaj tsis nqa lub load, nws raug tso cai rau weld 4 load- bearing ca steels ntawm ib qhov chaw, tab sis qhov deb yuav tsum tsis txhob ntau tshaj 150mm.
Lub sijhawm vuam tsis raug tso cai thaum lub phaj edging nyob rau hauv load. Lub edging phaj nyob rau hauv tib txoj kev raws li cov kabmob tiaj tus steel yuav tsum tau welded nrog txhua tus ntoo khaub lig bar.
Qhov kawg daim hlau ntawm stair treads yuav tsum tau welded tag nrho ntawm tsawg kawg yog ib sab. Lub vuam ntawm siab welded steel grating thiab ntsaws- hauv steel grating yog raws li nram no:
Cov incisions thiab qhib hauv cov hlau grating yog sib npaug los yog loj dua 180mm, thiab yuav tsum tau kho nrog hemming. Lub tiaj tiaj steel ntawm cov hlau grating tuaj yeem yog cov hlau tiaj tiaj tiaj tiaj, kuv- zoo li cov hlau tiaj tus lossis slitting strip steel. Lub thauj khoom tiaj tus hlau ntawm cov hlau grating tuaj yeem muaj cov hniav profile kom muaj zog tiv thaiv - plam quab yuam ntawm steel grating. Qhov tsawg kawg nkaus dav ntawm cov hlau grating ntawm cov hniav profile loj yuav tsum tsis pub tsawg tshaj 300mm.
