Cov yam ntxwv ntawm Scaffolding

Ntau hom kev tsim kho vaj tse siv scaffolding nrog ntau lub hom phiaj. Feem ntau ntawm kev txhawb nqa choj siv lub tais buckle scaffolding, thaum lwm tus siv gantry scaffolding. Feem ntau ntawm cov qauv kev tsim kho hauv pem teb scaffolding feem ntau siv coupler scaffolding, thiab qhov ntev ntawm cov ncej scaffolding feem ntau yog 1.2-1.8 meters; Kab rov tav nrug feem ntau yog 0.9 ~ 1.5m.
Piv nrog rau cov qauv dav dav, scaffolding muaj cov yam ntxwv hauv qab no hauv nws cov haujlwm ua haujlwm:
1. Qhov sib txawv ntawm cov khoom tau txais yog qhov tseem ceeb;
2. Lub fastener kev twb kev txuas node yog ib nrab rigid, thiab lub nruj ntawm lub node muaj feem xyuam rau qhov zoo ntawm lub fastener thiab installation zoo, uas ua rau muaj kev hloov loj nyob rau hauv cov kev ua tau zoo ntawm node;
3. Cov qauv scaffold thiab cov khoom muaj qhov tsis xws luag, xws li pib khoov thiab xeb ntawm cov tswv cuab, qhov teeb meem tseem ceeb hauv kev teeb tsa qhov ntev, thiab eccentric loading;
4. Qhov taw qhia kev sib txuas nrog cov phab ntsa muaj qhov sib txawv tseem ceeb hauv qhov txwv ntawm qhov scaffold. Cov kev tshawb fawb ntawm cov teeb meem saum toj no tsis muaj kev sib sau ua ke thiab cov ntaub ntawv txheeb cais, thiab tsis muaj cov xwm txheej rau kev soj ntsuam qhov tshwm sim ywj pheej. Yog li ntawd, tus nqi ntawm cov qauv kev tiv thaiv multiplied los ntawm kev hloov coefficient tsawg dua 1 yog txiav txim los ntawm calibration nrog rau yav tas los siv kev ruaj ntseg yam. Yog li ntawd, txoj kev tsim qauv tau txais hauv qhov kev qhia tshwj xeeb no yog qhov tseem ceeb semi probabilistic thiab semi empirical. Cov xwm txheej yooj yim rau kev suav tsim yog qhov scaffold ua tau raws li kev tsim kho uas tau teev tseg hauv qhov kev qhia tshwj xeeb no.
