Izinguquko zini phakathi kwezindlela zokusebenzisa amasikhala wezindlu zokuphambana nokuphambana ngamagqambo?

Igama lisibonisa isiqondiso esinye, kodwa akasibonisi sonke

Ukuphambana kwe-scaffolding oyishaya ngaphansi kwakho naseyishaya ngaphezulu kwakho kusobonakala njengokuba kubalulekile ukuthi kubhekisele kubizo lobizo. Akubalulekile. Ukuchaza kubalulekile kwezindawo—ukuphepha, ukusebenza ngokulinganayo, nokuthi amaqembu ayakhuluma njani ngaphakathi kwesithuthi.

Isikhumba sokugcina isikhumba esisodwa ngokufanayo nokubuka kwe-"U" okungahleli, noma isikhumba sesisikhi. Isibonelo sokuvula esikhundleni sokuphakama kusiza abasebenzi, izinto zokusebenza, nezinkambo ezingaphansi ukuphuma ngqo ngaphakathi kwesikhumba ngokuphakama kwesikhumba sokugcina. Lokhu kuyisahluko esibalulekile kumfanekiso wokusebenza kwe-scaffolding yezinhlobo zezincwadi zezinkambo nezincwadi zezincwadi.

Izikhumba zokugcina azifanele ukuthi zihlwe. Kufanele kubekwe isithombe sokufika emuva kwesikhumba. Lokhu yindlela esibalulekile yokuphepha okungabonakali kumbili wemisebenzi.

Ngaphandle kwalokho, isikhumba sokuhlwe sifanele ukuthi sibe amasithombe noma amasithombe asingaphansi kumfanekiso wokusebenza, ukusiza abasebenzi ukuhlwe ngqo ngaphakathi kwesikhumba ukufika emaqondweni amaningi. Umfanekiso wokusebenza uyasebenza njengesikhumba sokuphakama futhi njengesithombe sokufika.

Ukuchaza ukuthi umfanekiso wokusebenza ubuyekezwa kanjani ekusebenzeni

Umgomo wokubala uyabona indaba empilweni. Amaphrame okuhamba phakathi ayabeka isikhombisa esikhulu—kunye nesikhundla esisodwa (sikade kusuka ku-2 meters (6 feet 6 inches) emhlabathini)—ngaphandle kokubhekana komphakathi wokuphambuka. Amaphrame omgqa ngaphezulu neyodwa ayabeka umkhawulo wokusebenza ngaphandle kokukhupha isikhundla sokuhamba.

Amaphrame okuphambuka ngaphezulu, okanye amaphrame okuladela, aneemphakathi noma amaphuzu akhulwe kumphakathi wokusebenza. Lezi phrame zinamakhanda amancane ngoba amaphuzu ayasebenza kusikhundla esingasodwa. Isibonelo sokuthi abasebenzi abangadinga iladela eyodwa ukufika emaphakathini amaningi—baphambuka kuphela.

I-OSHA ikuvimbela ngokucacile ukukhuphuka izinsimbi zokwakha eziseceleni kwe-scaffold. Yilapho umehluko uba obaluleke khona ngokomthetho. I-scaffold engagibeli ngaphandle kwesitebhisi sokufinyelela esifanele imema abasebenzi ukuba bakhuphuke isakhiwo ngokwasookuwukwephulwa okuqondile. Izinga le-OSHA 1926.451 ((e) ((1) lidinga ukuthi abaqashi banikeze ukufinyelela lapho amapulatifomu e-scaffold engaphezulu kwamamitha amabili ngaphezu noma ngaphansi kwendawo yokufinyelela.

Lapho Yonke Imiklamo Inengqondo

Amaphramu okuhamba phakathi ayasebenza kahle kumazwe apho ukudlula kwemithambo kuyisisekelo esikhulu nokuthi ukudlula kungakhohlwa. Umsebenzi wokufaka amasango uyisibonelo esihle—amaphramu okuhamba phakathi asinika ubude obukhulu ngalokho kwenye indawo futhi akunciphisa ukusakaza kwemithambo emaphakathini amaningi. Isigaba sokufaka amasango esihamba ngamaphepha emasango kusuka kuqondile elide sifuna ukuthi sihambise imithambo ngokuhamba phakathi, kodwa akufanele siyilandelwe noma siyilwambule.

Amaphramu okuphuma phakathi ayasebenza kahle kumazwe apho ukufinyelela kusuka kusuka kusuka kuyisisekelo esikhulu futhi ukudlula kwenkundla ayikho isisekelo esikhulu. Amadwaleni amancane ebandla apho amaphakathi amancane akhona amanqina amancane ayafuna amaphramu okuphuma phakathi ngoba ahlula inkinga yokusebenzisa amaphakathi okuphuma—kunye kwezinto ezincinci zokugcina, kunezinto ezincinci zokuhambisa.

Izindlela zokuphatha izilwane zokufaka emkhakheni kweGulf Coast ziyabonakala. Amaphuleli kufuneka bafikele ku-manyathelo amaningi kwe-column ya-destillation ukwenza ukubona. Izifreme zokuphuma kuzo zavumela amaphuleli ukudlula ngaphezulu nezansi ngaphandle kokuguqula izilwane zokuphuma, kususa isikhathi esingama-30 minithi ngalendlela yokuqonda ngalendlela. Kodwa ngalesi sikhundla, kuma-rack ayenamaphipe okuphakama kwezimetro eziningi, izifreme zokudlula kuyasebenza kahle—amaphuleli abadlula ngaphakathi kwe-rack ngokuthenga izinto ngaphandle kokuphuma ngaphakathi kakhulu.

Izimplication zokuphepha azisemthwakathi

Izidata za-OSHA yeyishwa le-2025 zibonisa ukuthi izivumelwano zokusebenzisa izilwane zokufaka zihlanganise izinkomba ezingama-1905 . Lokhu kukhupha ukuthi kunezinkomba ezingama-32 ngaphezu koyishwa elidlule . Iindustri ezinamandla kakhulu ekukhombeni izilwane zokufaka ziyi-masonry, roofing, framing, ne-siding .

Amazwi amaningi awo akhuluma ngokufinyelela. Abasebenzi baphuma kwezincwadi zokusebenza zokuphuma kwezincwadi zokuphuma ngokungakho kweladder. Noma bavula izincwadi zokuphuma njengamathuba okuphuma—okuyisibonelo esingasitholakali.

Lokhu kukhona—umkhakha wokuphuma nge-ladder oyisifungo esihle. Umkhakha wokuphuma ngaphandle kweladder uyisibonelo sokubhukuda. Ukudesign akuyi-ndlela eyodwa yokubhukuda; isikhundla sokugcina phakathi kokuthi ukudesign kusinika noma isikhundla sokusebenza kusinika siyisikhundla sokubhukuda.

OSHA iyabiza ukuthi ukufinyelela ngqo ku- or from another surface kufanele kube phakathi kwezindawo ezili-14 inches ngokwahlulela futhi ezili-24 inches ngokuphakeme. Lokhu kusho ukuthi nangokuphuma ngokuphuma, izirungu ziyofanele kube phakathi kwezindawo zokuphuma futhi ukufinyelela kufanele kube yisibonelo sokuhle.

Okuthi izindlela zokusebenza zizisa

Ukuqondisa ukuthi izikhanda zokuphakama ezisemzini zase-Kanada zibiza ukuthi izikhanda zokuphakama ezinamaphuzu zokuphuma azifanele ukuthi zizweke—kufanele kubekwe isithombe sokufika. Lokhu akuyi nkonzo yokuhlinzekile; yilokho okubalulekile kakhulu ekuphakameni okwenzeka ngokwesayizi yayo.

Izistandadi ze-ANSI ne-OSHA zihlukanisa ukufinyelela kwezikhanda, nakuba zihlukanisa ngokwesibonelo esahlukene. Isibonelo esibalulekile sisodwa: izikhanda zokuphakama ziyiziqondiso zokuphakama, akuzi zinkambo zokuphakama. Ukusebenzisa zazo ngokwesibonelo esibe sibini kukhona ukuthi iziproblemi ziqala.

Kulokho okuphakamayo kwezikhanda, umba wokuphakama kufanele uqinisekise ukuthi akukho 16¾ inches (43 cm) phakathi kwamaphuzu. Lokhu uyisibonelo sokuthi abasebenzi baphakame ngempilo ngaphandle kokuphakama kakhulu. Izikhanda zokuphakama ezingenamaphuzu akuzikwazi lokho ngoba azifanele ukuthi ziphakame—kepha lokho kusho ukuthi kufanele kubekwe indlela eyodwa yokufika.

Izinkinga zokusebenza kwezindawo zokusebenza

Ukukhetha phakathi kwezinhloso ezimbili akuyi kuphela ukuthi kufanele kubhekwe ukuthi kufanele kubhekwe ukuphakama—kuyi ukuthi indawo iyasebenza njani.

Ukubeka kwezindawo kubalulekile. Isikhalazi sokugcina isikhumba sikhona ngokwanele kumathuba okuphakama nokulula, apho abasebenzi nabazalwane badinga ukudlula ngaphansi kwesikhumba. Isikhalazi sokuphuma ngaphansi kwezikhumba kufanele kangako lapho isikhumba senqanaba esincane kanye nokufinyelela ngokuphakama kuyisibonelo esisodwa.

Ukuqonda kwezibutho kubalulekile. Izibutho zezokuphatha izinto zinkulu zizoyazi ngokujwayelekile isikhumba sokugcina. Ukufunda isikhumba sokugcina ngaphezu kwezikhumba zokuphuma ngaphansi akukho mthwalo omkhulu—kepha izinhlobo zokufinyelela ziyisibonelo esisodwa. Izibutho ezizoyazi ukuphuma ngaphansi kwezikhumba zingasiza ngokuzenzakale isikhumba sokugcina uma ikhaladi ayikho ngokushesha. Lokhu yisibonelo sokuhlolwa, akukho phutha lokusakha, kepha yisibonelo esisodwa.

Ukusebenza kwezinto zokuzalwa ngokulinganayo kunciphisa isibonelo sokwahlula. Uma umsebenzi uyabhekana nezinto eziphakeme noma ezingabi ngezinye izinto ezinkulu ezidla ngaphansi kwesikhumba, isikhumba sokugcina sisebenza ngokulinganayo ngokuphelele. Uma umsebenzi uyisibonelo sokubheka noma umsebenzi ophakeme kunezindawo eziningi zokuphakama, izikhumba zokuphuma ngaphansi zicimisa inombolo yamachepu futhi zihlela ukusakha.

Ukulahla Kwemali Engafihliwe

Ukukhetha isithili esingasemthwakathini sibangela ukungafanele kwezinkinga ezihlukahlukene okuzokwenzeka ngokuphelele kwesikhathi sokusebenza. Isithili sokuhamba phakathi kwezinkinga ezingaqinisekile ngokuphelele kwezinkinga zokufinyelela ngokuvutha kusenza abasebenzi baphathe amakhanda nabo noma bavuleka isikhathi sokuhamba ngaphezulu komkhosi. Isithili sokuphuma phakathi kwezinkinga ezingaqinisekile ngokuphelele kwezinkinga zokuhambisa izinto ezihlukahlukene kusenza abasebenzi baphinde baphinde baphakamisa izinto ngaphezulu komkhosi noma ngaphandle kwemikhosi.

Akukho yizinto ephambili kakhulu, kodwa zonke ziyabonakala njengokungafanele kwezinkinga. Umphumela wokugcina ngeminyaka noma ngemizuzu uyakwenzeka—ngamahora wezisebenzi, ngokuphulukana kwebasebenzi, nokubonakala kwamaphoyisa okungakwenziwa.

Indawo yomsebenzi eyodwa ePacifc Northwest ibayisebenzisa amafremu okugqibela kumsebenzi wokubuyisela indlela. Amafremu abhaleka kahle kumsebenzi wendawo, kodwa xa intombi yadlula kwindawo engaphansi yokufaka i-coating, bafindile bakhupha ngamafremu ngokuphelele. Bazibeka amafremu okukhupha kwindawo engaphansi kumsebenzi futhi babhekisela isikhathi sokufinyelela ngemiphumela yezilinganiso zezingu-40%. Indaba ayikho ukuthi indlela eyodwa iyabonakala kahle—kuyiyo indlela eyodwa ekhethwe ngokwesikhathi somsebenzi.

STEEL Shanghai Import & Export Co., Ltd. iyathumela amasistimu we-scaffolding we-walk-through ne-climb-through ezenziwe ngokwesifundo sezinsizakalo zezindawo nezimithombo zokuload, nangokwesifundo esihambisana nomlando wokusebenza nokuhlinzekwa.
