Iphlanki yesilika esihlanganisiweyo yamakhanda engqonyeni emehlweni ethulwini

Indlela isiphawulo esihlanganayo sikhuthaza ubunzima bephlanki yamakhanda wesilika

Izihloko ezimbambene nezinqumo zazo ekulungiseni ubunzima bezaphawulo zamakhanda ephawula

Izihloko ze-Offset zisebenzisa izandla eziphambili ukuze kwenzeke umgwaqo ozivikela okungavuleki kwesikhathi nekungahleli kwezondlo. Isakhiwo esihlukahlukene sibophepha ukuthi iplank ingxenye ngemithwalo, kushumayela imithwalo eminingi yezinkonzo. Lokhu kusidla ukuthi kube nesilinganiso noma kungenjalo kumelwe kubekwe imithwalo ngendlela ehambili, into eqondene kakhulu emazingeni aphinde aphinde amelwe.

izinhlelo zezihloko ezingu-3 kanye nokukhokha kwebamba kwezondlo kuzinhlelo ezingavamile

Izimiselo ezingu-3 zehloko zinika inkululeko yokuphumula, kunciphisa ukuhamba kwegolide kanye nokubota kwephlanki nguya kuye kangakanani njengama-70% kunazo ezimbili. Iziphuzu ezikhutshangayo ezimbili kanye nomgwaqo waphakathi zithola umthwalo ophazanyayo ovela kumithwalo engaqedi, lokhu kuyakwenzela le nhlelo ibe yisilonda esifanelekileyo yizindlu ezihlala phambili kuzinye izindlu.

Isingathunzi konoma izihloko: Ukusebenza kuzindlela eziphethilweyo

Ipleni zengcinga eyodwa zisebenza kahle kumgama ozungezwe ku-20 feet, kodwa xa kudlalwa imigama emide kangaka, izinhlelo zengcinga eziningi zivumela izikhalo ukudala i-decks ephinde phinde ezithelezile ngaphezu kuka-40 feet ngaphandle kokudinga izipositi ezifutshane phakathi. Ukuchazwa kwempilo yonke kutholile ukuthi izihloko ezintathu zilondoloza amagapu ngezansi kuka-3mm ngasemgceni u-100, okuyinhambili engcono kunazo amagapu akhona a-8 kusuka ku-12mm angabonakala ngokusebenzisa izihloko ezingcwele. Indlela ethambekayo lezo zingcinga zifakelana futhi isiza ekuphatheni ukunyusa nokuncipha phakathi kwezindlu ezihambisanayo njengesimo sezulu sishintsha usuku lwesibusiso.

Iziprinsipi zomlando ngotho olungaqedi ngqo ngokusebenzisa indlela yokudityaniswa kweplank

Ukudonsela kwe-wedge nakhephu engaqedi kuvumela ukuthutha kwegevane ngokuphelele ngokungena komthwalo. Amahluko amahle (0.5–1.2mm) avumela ukuguqulwa kwesithelo kodwa akuvuni inkabi yezinto ezingaphakathi. Izimboni zokulungiselela nezihlalo ezibonakalayo ngomdlovu zinikeza inkinobeko yokuthi kusetshenziswa kanjalo, kuxhaswa ngefomu ye-OSHA yokuthi ikhanda lifakiwe kabonke (29 CFR 1926.451(b)).

Ingeniso Yomthwalo Nezenzo Zokukhazimula Zeplanki Yezilonda Yesikhangala

Okunye, okusekuhlengeni nokukhulu ingeniso yomthwalo weplanki yesilonda yesikhangala

I-OSHA isohlisa iziplanki zesilonda ezintathu: okunye (25 psf), okusekuhlengeni (50 psf), nokukhulu (75 psf). Lezi ziyingeniso eziphathelene nabasebenzi, izixhobo, nezinto njengeke zibe yonke ngasinye, iziplanki ezinezimo ezikhethekile zingakha kangakanani kakhulu kuzo zonke i-3,750 iphaundi ekhanda esisiseko se-5x10. Isilonda esikhazimulwe ngokushushu sinesimo esiphansi esingeni le-15–20% kunenduku, lokhu kususa ukugayaza phansi komthwalo.

Ukubala ingeniso yezimo ngemizimba yezimali ephethezwayo

Iphlanki yesitye zizokhutha kakhulu ukuba ibe yilipha ngalinye elingu-1/60 ngaphansi kwemithwalo ephindaphindwayo njengevivimba yephompi yesibovu (500 Hz), iziphazamiso (imithwalo engu-200 lbs ngendlela ethile), nemboni yezixhobo. Isifundo sakwa-2023 sabonisa ukuthi zizokhutha kakhulu 98.7% yemithwalo yokunqamula phakathi kokuphinda-phindwa okuchazela imini yendlu yasebenzi - kanti kancane ngaphezulu kuka-OSHA ngama-22%.

Isifundo sobuchwepheshe: Ukusebenza kwezihlangothi ezide zezingubo zophango lwesitye

Kumsebenzi woselukazi olunjalo, iplanki zesitye ezihlanganisiwe zabonisa:

METRIC	Ukulinganisa	ISiphazamo sika-OSHA
Ukungqubana okungaphezulu	0.82" emaphakathini angama-85	1.5" (ohlomo lengu-L/60)
Ukuguquka kwesikweletu	0.12" ngaphansi kwentliziyo engu-45 mph	0.25"
Ukumelana Nokukhathala	0% yokulahlekelwa emva kwezinyangeni ezili-18	ukungena kwegaziweyo okungaba khona 5%

Ukufakwa kwenzeke ngokushesha kakhulu ngama-37% kunazo zinye izinhlelo ezihlanganisa, nokuthi akukhathalwa konke okwenzekayo okuthintana nendiza emshenesheni.

Imitholampilo ye-OSHA namandla okuhlanjelwa kwezinhlelo zezinkawusha zezinkawu

Izidingo ze-OSHA ngamalinganiso endizini nemandla yomthelesi wokwakha inkawu

Umlawuli wokuphatha kwezempilo nokhathazeka kwemisebenzi unikeza izimo ezibophelela ngendlela amabhloko eflori angabamba ngaphezu kwesimiso esikhulu. Isimo sakhe sithi akukho mutholampilo angaphazanyiswa ngaphezu kwe-1/60 yesahluko sakhe sonke xa isilonda ngokugcwele, lokhu kakhulu kuyakulungisa izinto noma kunjalo umtholampilo uphinde uphinde ubambe izahluko ezine ngaphezu kwalokho akwakhiwe ngalo (lokhu yisahluko 1926.451(a) ekhodini le-OSHA). Amabhloko ebhuluki elimenyane ekufanelekileyo ayenzelwa kumaloyi amakhulu anobukhosi obunye obunye banguqulelo 36,000 iphaundi ngosiqhamo esinye ngaphambi kokuba aqale ukuguqulwa. Lokhu okubukhona kubangela ubukhuni besandla ngoba ubukhuni besandla kuphela kubambekile phakathi kwe-7,500 ne-9,000 psi. Ingxenekelo eya kusuka kuNational Safety Council engu-2024 yafumene into ethandekayo futhi: amasebe adlala abasebenzisa amabhloko ebhuluki ayengena ngaphezu kwebili ngamathathu engcinga mayelana nobuhlungu obukhulu bephazanyo kunazo ezenze ngokusebenzisa izinhlayiya ezihlangene.

Izinhlongo Ezizolwa Ngokugcwele: Izinholela Zokudlulisana Nezimiso Zokulungiswa Kweziviko

Ngempela yokuphepha, ukubeka izinkawu ngokuphambene kudinga ubude obungaphezu kwesikhombisa esithupha apho izigaba zihlangana futhi kumele ibe yintaka ngemizuzu engama-12 edlule amabhodi e-ledger ukuze kuthintwe ukuthi kube nemiphangalatshefako enzima. Izidingo zokuphepha ziya kuba nezimboni zingaphakathi kwezikhombisa ezine-42 noma ngaphezulu noma ngaphansi kwezikhombisa ezimbili, ngaphanda kwezimboni ezincane angaphansi kwezikhombisa eziphahla-3.5, ngaphanda kwebheshi ye-stell engamagauge angama-14 kuwo wonke amancane atholakala ukuqina okuchazwe kuzinto ezifika phansi. Xa kufika ekulandelweni kwezinhlobo ngemviko, izinkawu ze-stell ephambene zihlala zilungile kakhulu ngama-98 kabusha njengoba izihloko nama-notch zihlanya kahle. Lokhu kuyishisa izinqamlezelo ezintofu eziphila kuphela ngama-74 kabusha njengoba kuchazwe kudatha we-audit kusuka kumfundiso othile.
