Cov kev tsis sib xws ntawm grating feem ntau suav nrog cov khoom siv, qhov ntev, thauj khoom -cov kabmob muaj peev xwm, thiab txoj kev kho saum npoo. Cov khoom siv yog qhov tseem ceeb thaum xaiv grating; Cov khoom siv xws li steel, aluminium, fiberglass, thiab yas. Steel grating muaj lub zog siab thiab tsim nyog rau hnyav- qhov chaw thauj khoom, txawm hais tias nws yuav tsum muaj kev tiv thaiv kev tiv thaiv corrosion. Aluminium grating yog lub teeb yuag thiab corrosion heev-tiv taus, ua rau nws zoo tagnrho rau qhov chaw sab nraum zoov lossis qhov chaw ntub dej. Fiberglass grating muaj cov khoom zoo heev insulating thiab feem ntau siv rau hauv thaj chaw ib puag ncig cov khoom siv hluav taws xob. Yas grating yog tus nqi qis dua thiab haum rau lub teeb -load daim ntawv thov thiab kev teeb tsa ib ntus.
Dimensional parameters encompass lub grating qhov ntev, dav, thickness, thiab mesh loj. Ntev thiab dav yuav tsum tau txiav txim siab raws li qhov chaw muaj kev teeb tsa, thaum tseem coj mus rau hauv tus account qhov yooj yim ntawm kev thauj mus los thiab kev teeb tsa. Thickness ncaj qha cuam tshuam rau grating lub load-cov kabmob muaj peev xwm thiab yuav tsum tau xaiv raws li qhov tshwj xeeb ntawm daim ntawv thov scenario. Mesh me me cuam tshuam rau qhov cua thiab qhov dej ua haujlwm: qhov loj mesh qhib kom yooj yim dua airflow tab sis yuav txo tau cov load-cov kabmob muaj peev xwm, qhov me me mesh qhib muaj qhov cuam tshuam.
Load-cov kabmob muaj peev xwm yog qhov tseem ceeb hauv kev xaiv grating, feem ntau categorized rau hauv static loads thiab dynamic loads. Static load yog hais txog qhov hnyav ntawm qhov grating tuaj yeem txhawb nqa thaum nyob hauv lub xeev ruaj khov, qhov dynamic load tso nyiaj rau qhov cuam tshuam quab yuam tsim los ntawm kev txav ntawm cov neeg ua haujlwm thiab cov khoom siv. Thaum xaiv ib qho, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom muaj kev nyab xeeb txaus kom tsis txhob muaj overloading. Rau grating npaj rau cov neeg taug kev taug kev, qhov kev xav tau ntawm kev thauj khoom yog feem ntau tsis pub tsawg tshaj 1.5 kN / m²; rau txoj kev tsheb, qhov yuav tsum tau ua yog txiav txim siab los ntawm hom tsheb, nrog rau thaj chaw uas haum rau lub teeb tsheb feem ntau yuav tsum muaj peev xwm tsawg kawg yog 5 kN / m².
Cov txheej txheem kho deg cuam tshuam ob qho tib si durability thiab zoo nkauj thov ntawm cov grating. Kub-dip galvanizing yog ib qho kev tiv thaiv kev tiv thaiv- kev kho corrosion rau steel grating, muab lub neej ntev kev pab cuam. Cov tshuaj tsuag txheej muaj ntau yam xim xaiv thiab haum rau cov ntawv thov uas xav tau kev zoo nkauj siab. Aluminium grating feem ntau dhau los kho anodizing los txhim kho nws cov tawv tawv thiab corrosion kuj.
