Cov kav hlau square lossis lub voj voos hlau feem ntau yog siv rau hauv kev tsim kho thiab feem ntau yog siv rau kev txhawb nqa cov yeeb nkab, kev nkag mus rau qhov chaw ib ntus, cov phiaj xwm fais fab, kho kom zoo nkauj keel, thiab lwm yam.
Thaum qhov loj ntawm cov yeeb nkab steel hlau loj txaus, peb muaj peev xwm tsis quav ntsej cov txiaj ntsig ntawm cov ces kaum ntawm qhov hnyav, piv txwv li, cov kab plaub hau hauv cov kav dej, qhov hnyav poob los ntawm plaub lub kaum sab xis yog negligible rau ib feem loj heev. .
Txawm li cas los xij, rau me me cross-sectional square steel yeeb nkab, cov yeeb nkab steel yeeb nkab, nws yog ib qho tsim nyog yuav tsum xav txog lub vojvoog ntawm lub kaum sab xis R thaum xam qhov hnyav. Feem ntau, qhov kev ntsuam xyuas tsis suav nrog qhov sib txawv ntawm qhov hnyav li ntawm 5% mus rau 10%, uas cuam tshuam rau tus nqi ntawm cov khoom lag luam nyias. Yog li yuav ua li cas xam cov chav tsev qhov hnyav ib kab 'meter' square steel square steel yeeb nkab nrog R ces kaum?
Txhawm rau xam qhov hnyav ntawm ib chav tsev ntev ntawm qhov profile, feem ntau peb yuav tsum paub qhov chaw hla ntu thiab tom qab ntawd muab faib los ntawm cov khoom siv sib xws, thiab peb tuaj yeem tau txais nws qhov hnyav.
Rau lub raj duab plaub qhia hauv qab no, peb tuaj yeem yooj yim tau qhov chaw hla ntu A = H * B-(H-2t) * (B-2t) rau tag nrho seem yog tias peb tsis xav txog qhov cuam tshuam ntawm R-angle.
Thaum lub vojvoog ntawm lub ces kaum sab nraud paub tias yog R, peb tsuas yog ntxiv thaj tsam ntawm lub thaiv xiav thiab rho tawm thaj tsam ntawm lub block liab (raws li qhia hauv daim duab hauv qab no) kom tau qhov tseeb ntawm ntu. Thiab, rau feem ntau cov kab plaub hau, sab hauv thiab sab nrauv yog tib lub voj voog, yog li lub kaum sab xis sab hauv r = Rt. Tom qab peb txheeb xyuas cov ntsiab lus no, peb tuaj yeem yooj yim muab cov qauv hauv cheeb tsam.
Tsis tas li ntawd, nyob rau hauv cov lus qhia "GBT 3094-2012 txias-kos zoo li tus steel yeeb nkab", tau muab ib qho kev ntsuas qhov hnyav, nws txoj hauv kev suav thiab kuv tau hais saum toj no kuj zoo ib yam, koj tuaj yeem xa mus rau daim ntawv qhia nram qab no.
Saib xyuas cov qauv, peb tuaj yeem pom tias tus nqi ntawm R hauv qhov tshwj xeeb yog txiav txim siab los ntawm phab ntsa tuab ntawm cov yeeb nkab steel, yog li thaum koj tsis paub qhov tshwj xeeb R tus nqi npaum li cas, koj tuaj yeem coj tus nqi raws li qhov tshwj xeeb. , yog -
R = 1.5 npaug ntawm phab ntsa thickness thaum phab ntsa thickness yog ≤6mm. Thaum phab ntsa thickness> 6 hli, R = 2 npaug ntawm phab ntsa thickness
Hauv kev xyaum, peb kuj tuaj yeem suav cov chav ntsuas qhov hnyav ntawm cov raj duab plaub nrog lub kaum sab xis ncaj qha siv cov cuab yeej ntawm peb qhov chaw pov tseg.

Yuantai Delun feem ntau koom nrog "square steel yeeb nkab","rectangular steel yeeb nkab"thiab"round steel yeeb nkab", peb tuaj yeem sab laj thiab txiav txim nrog kev siv rau peb tus kheej qhov xwm txheej. Thaum kawg, los ntawm txhaj rau daim ntawv khawm ntawm lub kaum sab xis hauv qab, peb tuaj yeem kawm paub ntau ntxiv, suav nrog thaj chaw saum npoo thiab cov khoom siv kho tshuab ntawm profile, uas yog cov ncauj lus kom ntxaws heev.
