1. Cov qauv scaffolding yuav tsum ua kom paub meej tias tus ncej yog cov qauv ruaj khov thiab yuav tsum muaj lub peev xwm txaus, rigidity, thiab tag nrho 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 muab xam ntawm lub zog, nruj, thiab deflection ntawm formwork, ob sab nraud, thiab pob taws tseem ceeb;
(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 compressive lub zog ntawm cov to taub thiab hauv qab;
(5) Thaum teeb tsa lub qhov rooj qhib, xam lub zog thiab deflection ntawm lub qhov rooj qhib hloov dua tshiab nqaj;
(6) laij cov tshuaj tiv thaiv kev tawm tsam ntawm tus ncej thaum tsim nyog.
3. Thaum tsim qauv scaffolding qauv, ntsuas kev ntsuas ntawm tus ncej qauv yuav tsum tau qhia ua ntej, thiab cov pas nrig tsis zoo tshaj plaws, 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 hloov pauv lossis tsis muaj zog, xws li qhib qhov rooj, yuav tsum tau xaiv 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.
