Amanye amakhonkco avumela abasebenzi ukulungiselela izilingo ngokucophelelayo emkhakheni. Ubuhleli buphinde buchazwe ngokuthi kunezihlalo ezingavimbi futhi kunezikhonkco ezivamile ezilondoloza i-OSHA 1926.451 ngaphandle kokuthinta, nakuba ukuseta kuthatha iqembu le-cantilever noma ukudobela phakathi kwezakhiwo. Konke lokhu kusho ukuthi isikhangeli singabanjelwa kuze kube yisistemu ejwayelekile yokuphindaphinda okuphakeme engayibancula ngaphezu kwemitha engu-500 ngaloluqhuba.

Ukuguquka Kwesiqu Kusuka KuLimi NamaGolide KuZinga Lwe-Aluminium

Emva kwalapho isikhangeli saseyisikhathi siphakathi siyenza ngenduku nesitya, izinto ziyaluthatha kakhulu. Manje, kuphela kungu-92 iphesenti yezikhipheli ezintsha eziphumelela kusikhangeli kuyathatha amaplangi w-aluminum kahle kumsebenzi owudinga ngaphezu kweminyaka engu-6. Kungani? U-aluminum ungaqhubeka ngokudala kakhulu—kuphela kungu-15 iminyaka kunjalo kungu-3 ukuya ku-5 iminyaka kwezinhloso zenhlekele. Futhi, musa ucabange ngamathuba okulungisa. Isitya kudinga ukubekwa kwisilingo nguye ngonyaka ukuze kugcinwe ukuthi akunye. Uma kubhekwa izindleko ngokuphelele eminyakeni engu-10 kufaka phakathi ukubuyisela futhi ukususa izinto ezindala, izinkampani zilondoloza ngaproximately 45%. Kulawulo olwesithinta, kukhona into enkulu eyodwa: u-aluminum ungabalwa kabonakala. Lokhu kusho ukuthi akukho zindleko ezikhiya kwezimali ezingama-$150 ngayigrama kanye ngegama le-wood waste kuphela. Konke lokhu kuchaza kungani u-aluminum waba yisibonelo esiqine esisebenziswa kakhulu kumthombo wasikhangeli namuhla.

Izimboni Ezikhethekile Zezinqamulo Ze-Aluminium Scaffold Planks Ekugcineni

Umbono Othulasayo Ukuvinjelwa Kusukela Ngokushesha Futhi Kukhuliseke Okunakekayo Kwabasebenzi

Izinqamulo ze-aluminium zithula ngama-60 kabili kunazo eziqina ne-steel, okusho ukuthi amaphakheji ekugcineni angavinja izinkamelo ngandaba ngama-30%. Lokho ke kuyinto u-Institute yeKhuba leKhuba kuqondile kuhlaziywa kwalo ngo-2023. Izinto ezilula kakhulu zihlukanisa kakhulu lapho abasebenzi kudingeka bakhuphe izinto njalo ngesonto. Bahlatshelwa ngendlela engaphezu, futhi akudingeki ukusebenzisa izixhumanisi ezindebe ukwenza kuphela izinqamulo, lokho kunciphisa okunakekayo konke. Kuzindleko apho ukumisa kushintsha njalo ngesonto, le mina yizindleko eziphakamisa kakhulu. Hlola ishishini esisha se-high rise esenzelwe e-Miami. Lapho shintshela kuma-aluminum planks endala ne-steel, bazange bahlale banezimali ezingu-220 man hours ngonyaka. Kuyakwaziwa ukuthini kungani izinkampani eziningi zashintsha ngamanje.

Ubunzima Obuhle Kakhulu Nokudinga Okuncane Kokuphatha

I-aluminium planks ayizange ziqede njengomthi uma kusulela emva kokusebenzisa kungaphandle kwesikhathi, noma isitayile esitholakala khona. Ngokwemithombo yesikhathi sakugcina yezinhloso, lezi zi-aluminum boards zingasebenza kuthathu ukuya ku-5 amaxesha angaphezulu kunazo ezifanayo ezenziwa ngendlela eyisisekelo kumaseko. Isandla saso siphakeme kakhulu ngoba asimtholi izinto njengepenti noma ubuhlungu bomphango. Abasebenzi bafuna lokhu ngoba bangasiphazanya kuphela ngamanzi aphoqele ngaphandle kokulawula yonke lezi zinkinga ezidelekileyo ezidingekayo ukuze kugcinwe umthi ukuze kube nomdla phezu kwesikhathi. Kuyavumelana ngempela xa kufikirwa ekugcineni izindleko zokuhlenga phezu kwesikhathi.

Ukukhathazeka Kwesililo Kuzindawo Zokusebenza Ezine Sililo Nenhliziyo

Ilaya yesi-oksidi esihlaza phansi kwe-aluminium siphatha ukuphatha kwakhe konke kususela kuhlaza nokulwa ngokwayo, oku kubalulekile kakhulu emakhaya apho kudingekile ukuthi kufakwe ezingeni noma phakathi kwezinhlelo zomphakathi.

Sibona izimbono ezifanayo emkhondo wezempahla ezenziwa ngamahhala futhi. Amayizini amahhashi afana nale asemakhosini akhathazeka kakhulu kumthwalo wamanzi noma we-steel ngokushesha, kodwa i-aluminium isabeka kahle kulezo zimo ezimbi ngexesha elide.

Ukhefeshiwe Kude Kunesikhathi vs. Izincobo Zeplanki Ezintliza

I-aluminum planks zilima ngaphezu kuka-20% ukuya ku-30% kungethu, kodwa zahlinza ngokungu-40% ngonyaka ezingu-5 ngokwesithathu se-Construction Economics engu-2023. Lokhu kuthetha ukuthi zilapha ngama-15 ngaphezulu akulula kuthi kufaneleke kube yisikhathi sokubuyisela futhi. Kungani lokhu kuhlala kumele? Akukho hlanga noma inhlawumbisi yokuduna, okuhlinza imali ekulondolozini. Futhi, akukho muntu ofuneka alimele $3.50 ngalinye i-linear foot ngalinye igcina leminyaka. Lapho kusasa kusuke kuzigcwalisa, i-aluminum kuphela eyagcwaliswa ngokuphindwe, kodwa i-wood ethintekile ihlala eziphakamisini njengomnyango ophuthayo. Akuyona into enzima ukuthi abantu abangu-7 ku-10 basebenzisa i-aluminum njengesidingo esiphakeme sakho sika-scaffolding manje. Izinombolo zihlola phansi, nezimbili zabelwe kusukela ngo-2020.

Ingeni Lokuqhubeka Nokusebenza Kwesithunzi Se-Aluminium Planks

Imikhuba Yojeni Ngokwesayensi Yokuqhubeka Kwesithunzi

Izidingo zasekuhlaleni kusasa kufuneka ziyanze izinhlobo ezibhekene ngezinhlobo eziphakeme njenge-ISO 12811-1 nezinhlobo zikaOSHA 29 CFR 1926.451. Lezi zinhlobo zilondoloza izici ezifuna ukuthi kube khona okungenani 4,535 kg ngaphansi kwesikhwama esisodwa (noma amapond 100 ngaphansi kwesikhwama sesifooti esisodwa) uma sebenziswa ekusebenzeleni okuphephile. Izihlalo ze-aluminum esibonayo manje ziyafinyelela lezi zici ngokulandelana nokusebenzisa izimboni ezintsha njenge-alloy ye-6061-T6. Lokhu kusha kuyakhula kuqukethe izindlela zokuxhasa okuya kuye kangange 310 MPa ngokwesithathu sikaScaffold Industry Association esekwe ngojiye. Kanti lokho okukhanya kakhulu kukhona yini indlela engcono yokuba libandayo kunamathambo – ibiza kabili okungenani.

Ukuhlukaniswa Kwamandla: Izihlalo Ze-aluminium vs. Ezenzulu vs. Izihlalo Ze-steel

Ukukhetha kwezinto kubangelisa ngqo ubuhlobo, ubunzima, nokutholakala kwesikhathi:

Impahla	Ubunzima (kg/m)	Ubungozi Bekhanda (kg)	Uhlola Lwesibhedlela
Aluminium	8.2	5,400	Okuphezulu (25+ iminyaka)
Ithi	24.7	6,100	Ophakade (10 iminyaka)
Isihlalo Esilahlwayo	11.9	3,250	Okwaphansi (3-5 iminyaka)

Njengoba igolide inamandla aphezulu kakhulu ekugcineni, isilawuli siphumelela ngaphezu kwemithombo yombili ngamandla kumandla kumandla ngu 39%, kuvumela ukuthi izikhangeli zibe phezulu ngezinkinga ezincane ezenziwa yisisekelo kanye nokuthuthana okunembile

Ukuhlaziywa Kwempilo Kuye Kukuphakama Okwasezindaweni

Izivivinyo ezenzelwe eziphakathi kuzo zingu-12 zazifundeni ukuthi izinkamba ze-aluminum zilinda ngaphezu kuka-98.2% ye-quota yabo kuqala noma kube sele zisetyenziswa yini-nini ngokuphela kwiminyaka engu-5. Lokhu kubalulekile kakhulu kunamahashi ambalwa apho amahashi anconywa kuphela ngama-63%. Xa sibheka ezindaweni ekhona kuzo ubuchithanga obungcwele, njengezikhala zomkhumbi eSingapore, i-aluminum iyashisa ngoba ayiphili njengoko isiteel iyaphila. Sabona ubuyiselo obukhulu be-83% okuncane kunezinkamba ezidinga ukubuyiselwa ngokwesivivinyo seScaffold Performance Report ye-2024. Futhi, lezivivinyo zibonisa ukuthi le ndawo entsha ingahlanya amathathu kakhulu kunalo akubhalwe, ngaphezu kuka-40% kunesimo sezivivinyo seANSI/ASSE A10.8-2019. Ukuphepha akusolwandle lokho.

Ukulinganisa nokuhlanganiswa nezinhlelo zomkhumbi ezintsha

Izinkawu zezalumini zenzelwe ukuthi zifundeni kahle kumithombo yesikhangiso esinovusekelo, ekunikeza ubuchwepheshe obungapheli ngaphezu kwegunwa. Amathuba amanqaku kanye nokufaka okuphakeme akulungele izivumelwano ezinhloso, ekususa into yokuhlanganisa futhi ekuthintela isikhathi esingekhona.

Ukusetshenziswa okunjalo ngeSikhangiso seFreyimu, iTube-and-Coupler, neSikhangiso seSystem

Izinkawu zezalumini zisebenza kahle kuwo wonke amathuba aphepha esi sikhangiso:

• Ifreyimu yesikhangiso : Izinkawu ezingenanto zongeza ukusakazeka kwesilinganiso ngo 20–30%(isifundo sokuqasha kokubetha kwe-2023)
• Amathuba ka-tube-and-coupler : Amagugu afakiwe ngaphambi kakhulu ayalingana kahle namagugu esitshe, ekunika indlela yokukhokha kahle yezihlangothi noma izodwa ezingavumelekile
• Amathuba aphilangeleyo esi sikhangiso : Echazimisekile kumakonikela angezalungu, angezicupha, nangewedjhi-lock, ekuxhaseni izilinganiso ezidinga ku imitha 3.5

Lokhu kumelela ukuthi kungaphulangwe kusindiso xa kushintshwa izinhlayiya, okususa isikhathi esingahlawuleki ngokuphindaphindiwe ngu 15%kuzindawo zomsebenzi ezigcwele kwizimboni ezahluke.

Izinto ezinamandla okuguqulwa futhi i-Aluminium Platforms enokuchwaliswa

Abayikhiwa bafakela iziqhamo ezinokuthathwa usuku olulodwa okunye ukuze zilandelane nezidingo ezishintshayo zezindawo:

• Izihlangothi ze-end (ezinokugunyazwa kusuka ku-1.8m ku-4.5m)
• Izibhiji ezibambisana ukufinyelela emaqedini amaningi
• Izixhobo zeqhwa elingavuvanga ezilungile kwezindlebe ezide kuya ku-10°

Umkhondo wa-2024 wabukwa abasebenzi abangu-120 wabonisa ukuthi izinxenye ezihlanjululayo zezinhlayiya zambala izindleko zokugcina nge 34%ngokuphindaphinda kokusebenzisa futhi. Izinhlayiya nazo zingaphothe-khwa ngemiphefumulo yomdlalo ophakeme ukuze zilandelane nezimo zokuphepha zasekhaya—ngaphandle kokulahlekelwa kwezinkokhelo zokwenza, zibambe indima yokuphakama yomgcinilo wezimali 19 kg/m² .

Ubungqoleni bokufaka nokutholakala kwezinqaluba ze-Aluminium

Ukubeka okuphindekayo nokulungiswa okwenzelwa ukulungiswa kwesivinini

Okwamanje izinqaluba ze-aluminum zihlanganisa iziqhamo eziphindekayo nezinkcukacha ezenziwa ngokudibanisa ezifana nazo zonke izindawo ezingenalo fomu. Abasebenzi bacela kuphela izinye zazo lapho kudinga, ngamathuba acwalisa noma kancane amathathu ubude bezinkinga manje esivininini. Bakhwaze futhi ukubeka amavili amaningi njengeyodwa ngaphandle kokudinga ukugcina, lokhu kwenza kube yisikhathi eside sokulungiswa kwezandla noma ukulunga izigaba ngocebo. Ukulungiswa kusiva ukuthi akukho muntu ofuna ukulinda izicutshisiwano ezithile kusuka kumthengi. Izikhathi zokulungiswa zibuka phansi kakhulu futhi, oselungiselela phakathi kuka-35 kuya ku-40 iphesenti ngokushesha kunazo mazinyo e-steel eyayiyaziwa ngabantu bonke.

Ukusondeza kakhulu nokuncipha kwezikhathi abantu baphilayo

Amabhloko e-aluminum ayibi ngaphakathi kakhulu kwezintsho-60 kunemithi futhi mazibonakale izintsho-70 ngephandle kwezintsho, okwakha kube lula kumuntu omnye ukuzilanda emkhathini wokudala. Lezi zibhloko zinamaphepha athintekayo namakhanda atholakalayo, ngakho abasebenzi bangahlola izigaba zonke kizindawo ezintsha ngaphakathi kweminithi engu-3 kuphela. Lokhu kumele kuchithekile kakhulu ekugcineni imizuzu yamanje emaphrojekthi okulungisa apho imizuzu yonke ikhishwa. Ukuvikela okuphucake kunciphisa futhi amaphutha esihlangothini. Umdla wonke ubonisa ukuthi kukhona ukuphazanyika kwezintsho-28% emaphutheni ekugcineni kwindawo yokusebenza ahlobene nemikhono nezililo xa usebenzisa lezi zimpendulo ezingenanto, ngokuthinta kakhulu ukuthi akudingeki ukubamba kakhulu nokuhlolwa kwezinto njalo njalo usuku lonke.
