Kev nthuav dav sib koom ua ke hauv pob zeb yog qhov tsim nyog ntawm kev tsim kho hom no. Lawv yuav tsum tau ua rau vim li cas thaum lub pob zeb hardens, thiab tom qab ntawd nrog qhov sib txawv ntawm qhov kub thiab txias thiab kev hloov pauv ntawm cov av noo, cov pob zeb pob zeb sib cog lus lossis nthuav dav. Yog tias tsis muaj kev sib koom ua ke, tom qab ntawd vim qhov tshwm sim ntawm kev ntxhov siab sab hauv, ntau yam qauv deformations thiab tawg tuaj yeem tshwm sim, uas txo lub zog thiab kav ntev. Ua tsaug rau cov kev daws teeb meem zoo li no, nws muaj peev xwm faib tau qhov sib npaug ntawm cov khoom thauj ntxiv, tiv thaiv cov txheej txheem deformation.
Qhov kev nthuav dav yog tsim thaum tsim cov tsev ntawm txhua yam, txuas hniav thiab kev taug kev. Nyob rau tib lub sijhawm, nws tuaj yeem txhaws nrog plua plav lossis pob zeb, uas yog vim li cas nws yuav tsis ua cov haujlwm tiv thaiv uas tau muab rau nws. Vim li no, kev tu ncua sij hawm ntawm cov pob qij txha yuav tsum tau ua. Nws yog qhov ua tau los kaw cov pob qij txha hauv pob zeb siv cov khoom tshwj xeeb elastic uas tiv thaiv lawv los ntawm kev sib kis, tab sis qhov no yuav tsis cuam tshuam rau lawv cov khoom. Ua ntej pob zeb yog poured, expansion coefficient xam feem ntau yog ua.nto, txiav txim siab qhov dav thiab ntev ntawm cov seams, nrog rau qhov kev ncua deb ntawm lawv.
Thaum txiav qhov sib koom ua ke, koj yuav tsum tau coj los ntawm qee cov lus pom zoo:
- Ua cov txheej txheem raws sijhawm. Los ntawm kev siv thev naus laus zis, txiav lawv mus rau hauv cov pob zeb tshiab tam sim ntawd tom qab qhov chaw tau xuab zeb tuaj yeem hu ua txoj kev daws teeb meem. Yog tias kev ua haujlwm tau ua tiav ntau tom qab, qhov ntawd yog, thaum cov khoom tawv tawv, cov kab nrib pleb yuav tshwm sim raws cov npoo, ua rau cov yam ntxwv ntawm cov khoom tsis zoo. Tias yog vim li cas nws raug pom zoo kom txiav cov seams 12 teev tom qab nchuav, lossis ib hnub tom qab yog tias qhov haujlwm tau ua tiav ntawm qhov kub qis.
- Kev nthuav dav sib koom ua ke hauv lub tsev yuav tsum muaj qhov tsim qhov tob uas hloov pauv ntawm ib feem peb thiab ib lub hlis twg ntawm tag nrho cov tuab ntawm qhov tshwm sim screed.
- Kev txiav yuav tsum ua nrog kev ua raws li lub sijhawm ua haujlwm.
- Kev txiav mesh yuav tsum tsis txhob muaj cov seams sab hauv, vim tias kev tawg yog thawj zaug hauv cov ces kaum sab hauv.
- Shrinkage pob qij txha yuav tsum tsis txhob hla hauv T-zoo li, xws li kev sib txuas feem ntau ua rau cov kab nrib pleb los ntawm cov seam uas tshwm sim.
- Yuav tsum tsis txhob muaj thaj chaw nrog cov kab peb sab ntawm lub mesh, vim tias deformations feem ntau pib ntawm qhov kawg ntawm cov ces kaum ntse. Yog tias nws tsis tuaj yeem zam qhov duab peb sab, ces daim duab yuav tsum ua kom sib npaug.
Kev sib koom ua ketsim los tiv thaiv phab ntsa ntawm kev tawg thaum lub sij hawm thermal deformations. Nws tuaj yeem raug txiav txim los ntawm cov ntaub ntawv hauv qab no tias qhov deformations loj npaum li cas: lub tsev pob zeb, uas nyob rau ntawm qhov kub ntawm +20 degrees muaj qhov ntev ntawm 20 meters, ntawm qhov kub ntawm -20 degrees ua 10 millimeters luv. Ua ib tug seam nyob rau hauv daim ntawv ntawm tus nplaig, qhov tob ntawm uas yuav tsum yog kwv yees li 5-10 millimeters.
