Hauv cov txheej txheem ntawm kev tsim thiab ua cov kav dej square, muaj ntau yam tseem ceeb:
Thaum lub tog raj ntau lawm, xyuam xim rau lub caliber thiab raj kawg kom nws thiaj li yooj yim thiab ceev nyob rau hauv lub installation vuam txheej txheem.
Rau cov kav dej square nrog cov kab ntau lawm thiab cov phab ntsa tuab, ua tib zoo saib xyuas qhov kev txhawb nqa lossis cov hlua khi ntawm cov kav hlau kom tiv thaiv lub raj square ntawm lub voj voog lossis txoj kab uas hla deformation thaum lub sijhawm thauj mus los.
Qhov tseeb ntawm lub raj square yog qhov tseem ceeb heev.
Tsis txhob tom welding qhov ncauj. Ob lub welded npoo ntawm cov dov steel yeeb nkab yog flattened, thiaj li hais tias cov welded steel kav yuav zoo nkauj thiab standardized.
Qhov ncaj ntawm lub raj square tsis tsuas yog cuam tshuam rau tag nrho cov tsos, tab sis kuj cuam tshuam rau kev tsim kho tom qab vuam. Yog hais tias lub raj square yog twisted, nws feem ntau yog tshwm sim los ntawm qhov kev ntxhov siab uas tseem tshuav thaum lub tshuab dov raug kho kom zoo, qhov kev ntxhov siab seem tshuav thaum dov, los yog txias tsis sib npaug ntawm cov seem thiab ntev ntawm lub raj. Yog li ntawd, cov txheej txheem ntawm lub tsev kawm ntawv yog tus yuam sij. Los ntawm cov yas tortuous, qhov loj twists thiab tig mus rau hauv me me tortuousness kom tau raws li cov kev cai.
Qhov tsim nyog square raj tsis tsuas yog yuav tsum tau nruj me ntsis tswj qhov zoo thaum lub sij hawm tsim khoom, tab sis kuj yuav tsum tau ua tib zoo tshuaj xyuas tom qab tag nrho cov txheej txheem tiav los xyuas kom meej tias nws dhau los ua cov khoom tsim nyog thiab ua tau raws li kev xav tau ntawm kev lag luam.
