Scaffolding Raj Dev Xwv Nyob Rau Hauv Qab Tseg Muaj Zaj Lug

Yog li cas kev sib txuas pab tso caij ntseeg siab rau daim ntoo hlau scaffold

Cov khaub npawg sib txawv thiab cheeb kam rau kev tso caij ntseeg siab rau daim ntoo hlau sib txuas

Cov chaw tshaj siv qhov rooj twg kom tsim qhov kho rau nws tus kheub uas tiv thaiv kev faib tawm hauv qab zib thiab kev xeeb hauv tog. Qhov keeb kwm tsis muaj xws li no yuav tso cai rau kev sib txuas zoo tshaj taum kev siv, thauj cov cuab yeej rau ntawm ntau qhov sib txuas. Qhov no txhob kom muaj kev sib piv yog tias muaj kev thauj khoom tsis zoo, uas feem ntau pom nyob hauv qhov chaw ua haujlwm tshaj.

3-chawj systems thiab kev tswj kom tsis txhob muaj kev qhia tawm sab nraud nyob rau hauv cov kev xa khoom tshwj xeeb

Cov chawj muaj peb pawg muaj kev pab tso rau hauv daim duab peb npaug, txo kev qhia tawm sab nraud thiab kev rov qhov cub los ntawm 70% dua li cov chawj muaj ob pawg. Cov chawj nyob ib ncig tshaj tawm muaj kev pab tso rau hauv qab tshuab thaum muaj zog, ua rau cov chawj no tuaj yeem siv tau rau hauv cov platform tshaj tawm los ntawm cov chawj pib.

Ib chawj vs. ntau chawj: kev ua haujlwm nyob rau hauv cov kev xa khoom tshwj xeeb

Ib qhov chaw tshuab tuaj noj zoo rau kev sib txig txig nrog ib cheeb tsheb ntev txog li 20 feem, tab sis thaum kawm ntev dua, cov chaw tshuab muaj ntau qhov chaw tuaj yeem pab rau cov neeg tsim kho tsim cov kab rooj ntev dua 40 feem tsis tas yuav tsum tau muaj cov dej num ntxiv. Kev sim nyob hauv daim ntawv qhia pom tias qhov chaw tuaj thiab peb lub tsev tuaj nyob saum 100 qhov chaw tuaj yog qhov tsawg dua 3mm, uas zoo dua heev kom rau qhov 8 los ntawm 12mm uas feem ntau pom nrog qhov chaw tuaj ib qhov. Qhov kev sib txig txig tshwj xeej ntawm cov chaw tuaj no kuj pab tswj kev ntuag thiab kev hlaws ntawm cov planks nyob ib ncig thaum kaw lug hli ntawm hnub.

Cov lus qhia kho tshuam nyob saum kev sib thooj sib sau nrog kev sib thooj sib sau ntawm kev tsim kho

Kev tso kis tshwj tsis siv qhov wedge thiab chaw tso rooj tshuam ntxiv rau kev sib txuas 360° los ua kev sib poob zog. Kev tsim kho tshwj tsis muaj qhov hluv (0.5–1.2mm) kom muaj kev txias thaum kub, tab sis tseem txaus siab tias tsis muaj dej thiab vaj voos hla tawm. Lub tshuab xa tawm thiab lub nplhaib muaj leej nplua npluaj siv rau kev pom tias kev xa tawm tau raug lawm, tiam siab rau kev nyob rau hauv OSHA cov luj lawm rau platform (29 CFR 1926.451(b)).

Zog tso caij rau kev pab tshuab thiab kev ua haujlwm ntawm scaffold steel plank

Zog tso caij rau kev pab tshuab rau cov scaffold steel plank: yooj yau, me me, thiab loj

OSHA xwki cov steel plank rau hauv peb hom: yooj yau (25 psf), me me (50 psf), thiab loj (75 psf). Cov zog no txiav txim siab rau kev pab tshuab rau tus neeg, tshuab, thiab khoom tshuab ib txhiab, uas cov zog loj tuaj yeem pab tshuab dua li 3,750 pounds nyob rau hauv lub platform tshwj tsis 5x10. Steel uas tau txais kev txhim kho los ntawm kev ntxuav tso tseg tau nce zog ntau dua 15–20% dhau wood, yog li nws tsaus dua thaum muaj zog tso caij.

Xaiv xyuas kev ua haujlwm ntawm zog tso caij nyob rau hauv kev tshuab tshiab

Zaj planks rov tshwm sim nyav rau sab 1/60 ntawm qhov yuam sij hauv kev cuam tshuam zoo li kev sib txig sib tog ntawm concrete pump (500 Hz), kev ntxoov ntxooj ntawm chav kub (200 lbs kev ntxoov ntxooj tsis tas), thiab kev sib zog. Nyob rau hli 2023 pom tias lawv muaj 98.7% ntawm kev txaus siab hauv kev sib piv txwv uas sim kev siv hauv hnub sib tham—raug dua OSHA’s safety benchmarks los ntawm 22%.

Lub thawj leeg: Qhov siab tshaj plaws ntawm kev ua haujlwm ntawm zaj scaffolding planks

Nyob rau hauv lub project 42-txoj, cov zaj planks uas tau sib sau ua ke tau tshwm sim:

Metric	Qhov teeb meem	OSHA Limit
Qhov yuam sij siab tshaj plaws	0.82" nyob rau 85' elevation	1.5" (L/60 rule)
Lateral displacement	0.12" nyob rau hauv 45 mph wind	0.25"
Zog tshaj tawg nyob rau hauv kev pheej hmub	0% kev suab xyeeb tom qab 18 xyoos	5% kev suab xyeeb txhob ntxiv

Kev xa tuag tau 37% siab dua li kev xa tuag siv khoom sib txig, thiab tsis muaj kev phom sij dab tsi nyob rau hauv kev xeem kom meej tias nyob rau hauv kev xeem tsev neeg.

OSHA Txhawb Kev Nyab Xeem thiab Luj Kev Nyab Xeem rau Scaffolding Steel Plank Systems

OSHA Txhawb Kev Rau Ntau Thiab Zog ntawm Vaj Voog rau Scaffold Planking

Kev Pab Thaum Muaj Kej Dla Hlub thiab Kev Nyab Xeeb (OSHA) txhob nruab ntev tias lub qhov raj tuaj yeem kuab thaum muaj ntau zog. Lub tshuab neeg hais tias tsis lees yuav tsum kuab ntau dua li 1/60 ntawm qhov ntev tag nrho thaum muaj zog loj, uas tseem tiv thaiv kev nyab xeeb, hauv qhov chaw raj no tsuas yog tiv tauj ntau zaus plaib rau li qhov nws tsim los. (qhov 1926.451(a) hauv daim duab OSHA). Cov raj feem ntau tsim los ntawm cov hlwb meej heev uas muaj zog tshaj 36,000 paus kawg ib square inch ua ntej nws ploj form. Qhov zog no zoo dua raj dev ntau vim tias dev siv tshaj tshiab yog tshaj 7,500 mus rau 9,000 psi. Ib tug rapheev tiag tus Tsoom Hwm Kev Nyab Xeeb Ntawm Teb Chaws (NSC) piav tseg 2024 pom ib yam yooj yim: cov chaw ua haujlwm siv raj feem ntau pom nearly two thirds thauv tsis muaj teeb meem ntxiv rau qhov kuab ntau kom compared to those using composite materials instead.

Cov Koom Haum Raj Tag Nrho: Luj Kev Kawm Thiab Kev Tiv Thaiv Txoj Siab

Rau kev nyab xeeb, kev siv txoj pa roj tshuab yuav tsum muaj qhov kho taw tes tsis pub siab dua 6 inches thaum cov chaw txuas ncig nruab ntej, thiab yuav tsum muaj qhov kho taw tes siab li 12 inches npaum siab rau hauv qab ntawm lub ledger boards kom txhob tsim qhov chaw nyuaj siab. Lub tshuab nyab xeeb xav tau cov kab roj siab li 42 inches, tsis pub siab lossis me dua 3 inches, thiab muaj cov pa roj toj av siab tsis siab dua 3.5 inches, thiab muaj cov mesh thaub loj 14 gauge sib xyis txog tag nrho qhov chaw uas tsis muaj dej num kom dhau cov ntaub ntawv hlau nyiag uas nyiag los. Thaum pib mus xyuas kom pom tias txoj kev siv tshuab sib thooj xwm, cov pa roj thaub loj sib khaum zoo ib leeg ib yam sib tshooj tseem ceeb tuaj yeem muaj feem tshuaj txaus siab txog 98% vim tias lawv cov kab ncaub thiab qhov kho taw tes sib khaum zoo ib leeg ib yam. Qhov no zoo dua li cov pa roj txwv qhuas uas tshwj tsis pub muaj feem tshuaj txaus siab tsuas yog 74% raws li cov ntaub ntawv xyuas ntxiv los ntawm cov koom haum xyuas tshuaj sib tov.

Sib piv kev tswj hwm tshuaj txaus siab thiab kev ua haujlwm meej ntsis hauv kev tshuab siv tshuab

Qhov saab ntawm qhov chaw pheej steel txhawj xeeb rau kev pom hnav ntau dua nyob hauv kev saib xyuas, ua rau yooj yim dua rau txhawb mus rau OSHA cov luj twg uas sau tias tsis pub siv planks dua li 10% ntawm qhov muaj peev xwm. Cov kev kho tshuaj sib koom yog ib yam li no, tsis tas kho los kho dua, cuam tshuam 33% thaum rov kho kom zoo siab tias nyob rau hauv cov luj tswj tswj hlis.

Cov kev txhim kho ntawm Steel Scaffold Planks dhau wood thiab composites

Steel scaffold planks muaj cov kev ruaj khov, siv ntev, thiab kev txaus siab tshaj wood thiab composites. Tom qab 10 xyli ntawm kev siv, steel tua 94% ntawm nws tus cwj pwm dawb—ntsim npaum li 62% rau treated wood thiab 78% rau fiberglass composites nyob rau hauv qhov kev xwm yeem zoo li cas.

Ke vam meej ntawm kev ruaj khov: Scaffolding steel plank vs. wood thiab composite

Thov duab tsis txhob khaiv, tshuaj, thiab tshuaj tiam uas ua rau kev phom sij rau cov khoom tshuaj organic. thaum lub planks txiav los ntawm dej lossis hluv qhov rooj 24 xyoos, thov duab tsis hlo li 5% ntawm nws lub zog tshaj tawm, thov duab muaj zog heev dua. thoob komposite nyob tau 15–20 xyoo, tab sis lawv yuav tsis tuaj zoo tshaj thaum uas sau nrog tebchaws (400°F) kom compared to steel’s 1,200°F threshold.

Kev tiv thaiv corrosion thiab hauv feem ntau ntawm kev tsim kho metal walkboard

Steel planks uas tau roj kom ntxuav nrog zinc (hot dip galvanization) nyob tau 3 mus rau 5 zaug ntev dua li cov metal tsis muaj kev tiv thaiv. Thaum muab mus rau hauv kev test nrog roj salt spray uas sim txoj kev nyob ib ncig sab nraud, steel uas muaj zinc coating tsis muaj leej twg pom tias muaj rust tom qab nyob ib si taus 1,000 teev. Qhov no yog ib qhov yooj yim heev kom rau aluminum uas pib muaj cov chaw khaum li 0.02mm ib xyoo. Cov leej ntsiag tug zoo dua thaum peb saib OSHA regulations uas tshwm nyob rau 2024 uas xav tau cov cuab yeej scaffold yuav tsum muaj kev pheej rau 20 xyoo tias tsis muaj corrosion. Cov neeg ua haujlwm nyob hauv kev tsim khoom tau pom qhov yuav tsum no thaum lawv xav kom ua haujlwm.
