9. Txhawm rau tiv thaiv tus ncej raj los ntawm kev khoov hauv siab thiab lub fasteners ntawm zawv zawg taub hau, qhov sib tshuam xaus ntawm txhua tus pas nrig yuav tsum muaj ntau dua 10 cm.
10. Yog tias muaj cov khoom siv hluav taws xob lossis cov kev tswj hluav taws xob, cov kev nyab xeeb deb ntawm cov kev tswj hwm kev nyab xeeb yuav tsum tau ua thaum erection thiab dismantling.
11. Thaum lub sijhawm lees txais ntawm Scaffolding, txhua qhov chaw yuav tsum tau kuaj xyuas, thiab kev lees txais thiab siv cov txheej txheem dai.
12. Ua ntej Scaffolding yog tsa, lub hau ncej, cov pob fasteners, xyoob hlau, thiab hlau xaim yuav tsum tau kuaj xyuas. Kev nkhaus hnyav ntawm cov leeg ntoo, corroded loj thiab tawg nrawm nrawm, thiab rotten xyoob rafts yuav tsum tau raug hloov thiab tsis siv.
13. Nws raug txwv kom ncaj qha rau qhov chaw ntoo ntawm cov ntoo hauv av thiab kho cov scaffolding rau cov qauv uas tsis muaj zog heev (xws li cov tsheb ciav hlau, cov kav dej, thiab lwm yam).
14. Cov laug cam scaffolding thiab scaffoldings yuav tsum tau yooj yim sib txuas. Ob qho kawg ntawm cov laug cam Scaffolding cov laug cam yuav tsum muab tso rau ntawm cov kab ntawv sib tw thiab tsau kom ruaj. Cov laug cam uas tsis pub cov pob txha scaffolding kom muaj cov pob qij txha ntawm vans.
15. Cov laug cam scaffolding thiab ramp laug cam yuav tsum tau nthuav dav rau ntawm tus ntoo khaub lig ntawm tus ncej. Ntawm ob sab ntawm cov kab ke nruab nrab, thaum kawg ntawm cov kab ke, thiab sab nraud ntawm scaffolding ua haujlwm nto, thiab 18cm High High Kev Tiv Thaiv Phaj yuav tsum tau ntxiv rau hauv qab.
16. Scaffolding yuav tsum tau nruab nrog tus ntaiv ruaj khov los pab txhawb cov neeg ua haujlwm nce thiab nqis khoom. Thaum nqa cov khoom hnyav nrog lub lift ntaus ntawv, nws tsis raug tso cai txuas lub cuab yeej lipa mus rau cov qauv scaffolding.
17. Tus thawj coj ntawm Scaffolding ua haujlwm yuav tsum kuaj xyuas scaffolding thiab muaj ntawv pov thawj sau ua ntej nws raug tso cai siv. Tus neeg saib xyuas kev ua haujlwm txij nkawm yuav tsum kuaj xyuas cov xwm txheej ntawm cov scaffolding thiab Scaffolding Cov laug cam siv txhua hnub. Yog tias muaj qhov tsis xws luag, lawv yuav tsum raug kho tam sim ntawd.
18. Nws yog nruj me ntsis txwv tsis pub siv cov ntoo ntoo, cov thawv ntoo, cib, thiab lwm cov ntaub ntawv tsim tsev los tsim cov pob zeb ib txwm tsis tu ncua.
19. Nws yog txwv tsis pub rub tawm cov xov hlau ntawm scaffolding. Thaum cov teeb pom kev zoo ib ntus, cov ntoo thiab xyoob scaffolding yuav tsum tau nruab nrog insulators yuav tsum tau nruab nrog ntoo crossbars.
20. Thaum txhim kho cov yeeb nkab steel scaffolding, nws yog txwv tsis pub siv bent, pluav, lossis cov kav dej tawg. Cov seem txuas ntawm txhua cov yeeb nkab yuav tsum yog kev sib cuam tshuam kom tiv thaiv kev txhaws lossis txav mus los.
21. Tus ncej ntsug ntawm cov yeeb nkab steel scaffolding yuav tsum muab cov kab ntsug thiab stably ntawm cov ncoo. Hauv av yuav tsum tau sib xyaw thiab qib ua ntej tso cov ntaub qhwv. Tus ncej ntsug yuav tsum tau them nrog kem hauv paus, uas yog ua los ntawm cov hauv paus txhawb nqa thiab kav dej welded rau lub hauv paus.
22. Cov pob qij txha ntawm cov yeeb nkab steel scaffolding yuav tsum tau sib tshooj nrog txhua lwm yam uas siv cov hinges tshwj xeeb. Lub pob khawm no yog tsim nyog rau txoj cai kaum, thiab obtuse cov ces kaum (rau kab pheeb ces kaum (rau kab pheeb ces kaum kev sib tsoo, thiab lwm yam). Lub pob taws bolts txuas rau ntau yam yuav tsum tau nruj.
23. Lub rooj sab laj Scaffolding yuav tsum tau tsau rau ntawm kev hla ntawm cov yeeb nkab steel scaffolding.
