Ibhothi Yokusakaza Kwesitshixo Somkhakha Nokubeka Kwezinkamba Zokuphatha Ngokupheleleyo

Ukuthi izikhombisa zihlukene zikuthuthukisa ukuthuluzela nokugcina njani

Ukusebenza kwemipangeli yezikhombisa zihlukene ukuthuthukisa ukugcina kweplanki yezinkolo zomthwalo yesithili

Amaphlankezi e-steel abasebenzisa kusuka kwe-scaffolding nesifunda esisembo sikhulu kungahleli phansi kwe-steel esihle esiphakeme ngokuphakeme kwe-30 ku-50%. Lezi zinye zezibambo ziyadala izindawo zokufana ozokuthi zizokubiza ngokukhulu, ngokulandela ukuchazwa kwe-Coatings Technology Institute ngo-2023. Isimo sesiqondiso sesidiamond sisebenza njengesifunda sokususa amanzi. Ngemvula noma emaphakade aphakeme, lokhu sifunda singasusa ubunzima bemanzi ngokuphakeme kwe-2.4 millimeters. Indlela lezi zibambo ziyasebenza kuyikuthi amaphuzu abantu ayabeka emaphakade aye asitsho ngokuphakeme kwezindawo ezithile kodwa akayisitsho ngokuphakeme kwezindawo zonke. Izivivinyo zokulandela izimboni ze-ASTM zibonisa ukuthi ukufana okuphakeme kuzokwazi kuzokhula kakhulu—kusha ngokuphakeme kwe-0.45 emaphakade amahle kuye kuzokwazi ngokuphakeme kwe-0.78 uma sibhalela emaphakade lezi ezisembo.

Ukulinganisa Ukusebenza: Amaphlankezi e-steel esihle vs. Amaphlankezi e-steel esembo

Izidata zomlando zibonisa ukuthi amaphlankezi esembo azisebenza kakhulu kunamaphlankezi esihle:

• kungahleli phansi kwe-72% kwezindlela zokuhlela emaphakade engezilili
• kungahleli phansi kwe-53% ukususa amandla nezinhlobo zezinto ezingaphakathi
• ukuphakanyiswa kwe-38% kwemiphumela yokuqondwa kwezimpilo zomsebenzi ngeminyaka yezinsuku ezingama-8

Amaphlanga amahlukene akufuneka abhekwe ngokuzimisa imikhosi emibili ne-3/10 ngokuphindaphinda ukusiza ukuthi kubuyiswe izindikimba zezinkundla zokuphatha zika-OSHA. A umsebenzi wokuhlinzekisa kwe-2023 wabonisa ukuthi izinhlobo zezinhlobo zezibhamu zizokugcina i-85% yezinkundla zokungafuni ukuphambana emva kwezinsuku ezingu-5, ngokusuka ku-27% kuphela kwezibhamu zezinsuku ezingaqondwa.

Ukuhlanganisa nezindikimba zika-OSHA ne-ANSI zezinhlobo zezibhamu zokuhlala

Izinhlobo zezibhamu zizokwenza ukuthi zihlangane nezindikimba ezibalulekile zezibhamu zokuhlala, futhi zizokwenza ukuthi zihlangane nezindikimba zokukhupha kuka-OSHA 1910.28. Zifika ekulangenisweni ngokusebenzisa:

1. Ukuphakanyiswa okuncane kwe-0.5 mm phakathi kwezintaba nezindebe (ANSI/ASSE A1264.2-2022)
2. Okungaphezu kwe-50% yokugcina kwezibhamu (29 CFR 1926.502)
3. Inhlobo engasivumelwani nendlela ephakanyiswe ngokulingana nezindlela zika-ISO 23599:2019

Izimboni zezigidi zokuhlinzeka zibonisa ukuthi izibhamu zezinja zezinhlobo zizokugcina isivumelwano sokugcinwa kwesikhathi sokuvalela sika-0.62 noma kude kuma-rain—sikhipha isivumelwano sokuphatha esikhathini sokuvalela sika-0.50 ngokuphindaphinda ngo-22%.

Ukuthi Kwenza Isiphumo Esikhulu Kwemithombo: Ukuphela Kwemithombo Ngemuva Kokusebenzisa I-Steel Plank Yokusakaza Embo
