1. Kev tsim qauv scaffolding yuav tsum ua kom cov thav duab ruaj khov thiab yuav tsum muaj lub peev xwm muaj peev xwm, kev ruaj khov, thiab tag nrho kev ruaj khov.
2. Tus qauv tsim thiab suav cov ntsiab lus ntawm scaffolding raws li cov qauv xws li cov qauv qauv, qhov chaw ua haujlwm, siv cov haujlwm, thiab thauj khoom.
Ntawm lawv, tus qauv thiab kev xam ntawm cov ntawv txhawb nqa formwork yuav tsum muaj cov ntsiab lus hauv qab no:
(1) Kev Xam ntawm lub zog, rigidity, thiab deflection ntawm formwork, cov pob txha theem nrab, thiab pob loj;
(2) cov kabmob muaj peev xwm ruaj khov ntawm txoj kev ua haujlwm;
(3) Cov kabmob muaj peev xwm ntawm lub hauv paus sawv ntsug;
(5) Kev Xam ntawm Lub Zog Compression lub zog ntawm kev txhawb nqa sab saum toj;
(6) Thaum teeb tsa lub qhov rooj qhib, laij cov zog thiab deflection ntawm lub qhov rooj qhib hloov dua tshiab nqaj;
(7) laij cov kev tawm tsam kev tawm tsam lub peev xwm ntawm tus ncej thaum tsim nyog.
3. Thaum tsim qauv duab scaffolding, cov qauv qauv yuav tsum tau xaiv cov kev ntsuas hloov chaw yuav tsum tau xaiv, thiab cov pas nrig feem ntau thiab cov khoom siv uas yuav tsum tau xaiv los ua cov khoom siv xam. Kev xaiv ntawm kev xam cov koog yuav tsum ua raws li cov kev cai hauv qab no:
(1) Cov pas nrig thiab cov khoom siv nrog lub zog loj tshaj plaws yuav tsum tau xaiv;
(2) Cov pas nrig thiab cov khoom sib xyaw ntawm cov seem nrog cov kev ncua ntxiv thiab theem yuav tsum raug xaiv;
(3) Cov pas nrig thiab cov khoom siv ntawm cov chaw uas cov qauv ntawm cov thav duab hloov lossis cov ntsiab lus tsis muaj zog xws li qhib qhov rooj qhov rooj.
(4) Thaum muaj lub nra hnyav rau ntawm Scaffolding, cov pas nrig nrog lub zog loj tshaj plaws nyob rau hauv ntau ntawm cov kev thauj khoom yuav tsum tau xaiv.
