Lub khob-nuv scaffolding muaj cov yeeb nkab steel kab, khob pob qij txha yog zoo ib yam li cov kab ke sib txawv hauv lub khob-hook sib koom tes. Lub khob-Hook sib koom ua ke muaj ntawm lub khob qaum-nuv, ib qho qis dua khob-nuv, ib qho kev sib koom tes qis, thiab tus lej PIN ntawm lub khob loj. Weld qhov txwv pins ntawm lub khob khob hauv qab thiab lub khob Upper Cup ntawm Uprights, thiab ntxig rau lub khob loj rau hauv Uprights. Weld Plugs rau ntawm tus ntoo khaub lig tuav thiab cov kab pheeb ces kaum. Thaum sib sau ua ke, ntxig cov ntoo khaub lig tuav thiab kab pheeb ces kaum rau hauv qis khob nuv, nias thiab tig lub khob qaum teb, thiab kho lub khob qaum teb nrog cov pins txwv.
1. Lub hauv paus thiab lub ncoo yuav tsum muab tso rau ntawm kab chaw; Cov ncoo yuav tsum yog cov ntaub qhwv ntoo nrog qhov ntev ntawm tsis tsawg tshaj 2 spans thiab tuab ntawm tsis tsawg dua 50 hli; Lub axis ntawm lub hauv paus yuav tsum txiav mus rau hauv av.
2. Scaffolding txheej los ntawm txheej hauv qhov kev txiav txim ntawm Uprights, cov kab laum, cov kab txiav hluav taws xob, thiab qhov siab ntawm txhua qhov siab yuav tsum tsis pub tshaj 3m. Qhov ntev ncaj ncaj ntawm cov ncej kab rov tav yuav tsum yog ≤RL / 200; Qhov tav toj ntawm crossbars yuav tsum yog ≤L / 400.
3. Qhov erection ntawm scaffolding yuav tsum tau nqa tawm hauv theem. Hauv qab qhov siab ntawm cov theem hauv ntej yog feem ntau yog 6 m. Tom qab erection, nws yuav tsum tau kuaj xyuas thiab lees ua ntej nws tuaj yeem raug muab tso rau hauv kev siv.
4. Qhov erection ntawm scaffolding yuav tsum sawv synchronously nrog kev tsim kho ntawm lub tsev. Txhua erection qhov siab yuav tsum yog 1.5 m dua li hauv pem teb yuav tsum tau tsim.
5. Txoj kev ntsug ntawm tag nrho qhov siab ntawm scaffolding yuav tsum tsawg dua li L / 500; Qhov siab tshaj plaws uas tau tso cai cuam tshuam yuav tsum tsawg dua 100 hli.
6. Thaum ntxiv canilever cov teeb ci sab hauv thiab sab nraum cov scaffolding, tsuas yog cov neeg taug kev cov nqaj neeg taug kev tau tso cai, thiab cov khoom ntim ntawm cov ntaub ntawv txwv tsis pub.
7. Lub ntsa txuas yuav tsum tau teeb tsa hauv txoj haujlwm teev tseg nyob rau lub sijhawm nrog kev nce ntawm lub txee qhov siab, thiab nws tau txwv nruj me ntsis kom tshem tawm nws ntawm yuav.
8. Qhov chaw ntawm cov txheej txheej ua haujlwm yuav tsum tau ua tiav cov kev cai hauv qab no: 1) Cov scaffolding hauv qab no yuav tsum tau npog, thiab sab nraud yuav tsum muab npog tag nrho, thiab cov duab sab nraud yuav nruab nrog cov footboards thiab cov neeg tiv thaiv; 2) Cov neeg zov me nyuam tuaj yeem teeb tsa nrog ob kab rov tav ntawm 0.6m thiab 1.2m tais-nuv pob qij txha ntawm ntsug ncej; 3) Kev ruaj ntseg kab rov tav hauv qab cov txheej txheem ua haujlwm yuav tsum teeb tsa cov "kev nyab xeeb kev qhia kev nyab xeeb".
9. Thaum cov yeeb nkab steel fasteners yog siv los ua kev txhawb nqa, thiab kab pheeb suab sib txuas, lawv yuav tsum ua raws cov kev cai tsim kho kom ruaj khov, lawv yuav tsum ua raws li kev tsim kho lub tshuab hluav taws xob "JGJ130-2002.
10. Thaum Scaffolding yog npaj rau sab saum toj, kev nyab xeeb, thiab kev tsim kho cov qauv qauv kom tau daws teeb meem sai sai.
