Tsis xav tias neeg koom ib lub tsev nrog lub fortress. Lub tsev yuav tsum muaj cov ntsuas kev ntseeg siab kom sawv ntsug rau ntau xyoo lawm, lossis ntau dua. Kev tsim lub tsev tsis yog qhov nyuaj tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv peb lub sijhawm, thaum cov thev naus laus zis niaj hnub no tau muab pov tseg rau tib neeg. Tab sis khaws cia rau hauv nws daim ntawv qub yog qhov tseem ceeb dua. Tib lub sijhawm, lub luag haujlwm tseem ceeb yog ua los ntawm lub thawv casing hauv cov tsev ntoo.
Tau kawg, tsim vaj tsev ntiag tug nrog rau lwm yam, ntau cov ntaub ntawv ruaj khov muaj qhov zoo dua. Txawm li cas los xij, ntoo muaj cov khawv koob tshwj xeeb, vim tias tseem muaj cov neeg qhuas txog kev siv tshuab zoo qub Lavxias teb sab.
Txoj hauv tsev shrinkage
Shrinkage yog ib qho zoo rau txhua lub tsev ntoo, uas yog vim lub ntuj tsim ntawm ntoo kom qhuav vim qhov txo qis ntawm noo noo. Hauv ib txoj kev sib txawv me ntsis, qhov no yog hu ua shrinkage. Cov txheej txheem no tuaj yeem cuam tshuam los ntawm ntau yam, suav nrog cov hauv qab no:
- thawjqhov ntau thiab tsawg ntawm cov khoom siv hauv tsev;
- hom ntoo siv;
- ntoo ua tshuab (tshwj xeeb ziab);
- tsim kev ua haujlwm;
- qhia qhov ntev ntawm lub tsev;
- lub caij tsim (lub caij ntuj no lossis lub caij ntuj sov);
- siv tshuab;
- kev paub ntawm cov kws tshaj lij, thiab, raws li, kev sib dhos zoo hauv tsev.
xav tau lub casing hauv tsev kuj yog vim cov ntoo nyias nyias nyias nyias. Ntawd yog, raws li qhov siab ntawm lub tsev, cov tsev yuav txo qis los ntawm 1 meter:
- los ntawm cov cav ≈ 150 mm;
- los ntawm ntoo (npaj thiab tsis npaj) ≈ 60 mm;
- los ntawm profiled ntoo ≈ 40 mm;
- ntawm cov ntoo laminated ≈ 20 mm.
Cov ntaub ntawv muaj tseeb dua muaj nyob rau hauv cov ntaub ntawv tswj hwm, tab sis nws tsim nyog xav txog tias cov ntaub ntawv theoretical yuav txawv ntawm cov cim qhia tau zoo.
Lub thawv casing yog dab tsi?
Cov khoom tsim nyog li no yog hu ua pigtail, lossis, hauv txoj kev nrov, lub casing. Qhov tseeb, qhov no yog lub thawv ntoo uas muab tso rau hauv qhov rais lossis ntoo qhib ua ntej qhov rais lossis qhov rooj raug teeb tsa.
