ib qho "upturn" beam feem ntau yog siv nyob rau hauv lub qab nthab ntawm ib sab pem teb uas sab saum toj ntawm lub beam txuas mus rau hauv lub qab nthab, thiab ib tug "poob beam" yog siv nyob rau hauv lub qab nthab hla lub chaw nres tsheb lossis qhov twg hauv qab ntawm kab teeb tsis txuas mus rau thaj chaw siv tau.
Lub hom phiaj ntawm txoj kab rov tav yog dab tsi?
Inverted beams yog muab los tiv thaiv nws qhov pom hauv thaj chaw qab nthab lossis kom muaj lub taub hau ntxiv raws li qhov xav tau. Cov girders muab rau ko taw hla choj hauv cov chaw nres tsheb ciav hlau yog cov piv txwv zoo ntawm cov kab hluav taws xob. Cov girders yog ua inverted kom tau txais qhov siab pom tseeb muaj rau cov xaim hluav taws xob thiab tsheb ciav hlau
Yuav ua li cas rov qab beam?
Lub nqaj Inverted yog a cov kab hluav taws xob muaj zog, ntau hom qauv ntawm nqaj-zoo li I beam, T Beam, L beam, thiab lwm yam. Yog li, qhov siab ntawm Inverted beam yog tib yam li qhov siab ib txwm ntawm lub nqaj, raws li tau pom nyob rau hauv raws li hauv qab no daim duab.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau yuav muaj qhov cuam tshuam ntawm cov kab txaij
A2A: Lub hauv qab qhov cuab lub zog ntawm slab yuav tsum hla hauv qab qhov cuab lub zog ntawm inverted beam. Qhov kev npaj no yuav ua kom muaj kev hloov pauv ntawm kev ntxhov siab los ntawm slab mus rau kab teeb.
Dab tsi yog qhov invert slab?
Nyob hauv engineering engineering, qib invert yog theem sab hauv ntawm cov yeeb nkab, trench lossis qhov; nws tuaj yeem suav hais tias yog qib "hauv pem teb". Lub invert yog qhov tseem ceeb rau kev txiav txim siab ua haujlwm lossis ntws ntawm cov kav dej.
