Kev thauj mus los ntawm cov rooj tog ntoo yuav tsum yog lub teeb, ruaj khov thiab tiaj tus. Nyob rau hauv tus txheej txheem ntawm kev thauj mus los, sim kom tsis txhob muaj kev puas tsuaj, thiab tso nws ruaj khov. Nyob rau hauv cov ntaub ntawv ntawm qhov chaw tsis ruaj tsis khov, pad ib co duab los yog nyias daim ntoo kom nws ruaj khov.

Lub ntuj thiab ib puag ncig-phooj ywg cov rooj tog ntoo nthuav qhia qhov kev zoo nkauj ntawm cov xwm txheej thiab keeb kwm yav dhau los, ua ke nrog nws cov kav ntev ntev thiab cov nqi sau siab, tau nrov nrog cov neeg siv khoom nruab nrab thiab qib siab. Tab sis feem ntau, cov rooj tog ntoo yuav muaj cov pob qij txha nthuav dav, vim tias cov rooj tog ntoo feem ntau muaj qhov tshwm sim ntawm thermal expansion thiab txias contraction. Yog tias tsis muaj qhov chaw nthuav dav, nws yooj yim ua rau cov rooj tog zaum tawg thiab deformation. Thiab qee cov neeg uas tsis paub yuav ua li cas nws xav tias nws yog cov rooj tog tawg, yog li cas txoj kev xaws yog tawg? Dab tsi ua rau cov rooj tog ntoo ua kom tawg? Cov rooj tog ntoo tiag tiag puas yog qhov teeb meem zoo? Kuv yuav ua li cas yog tias kuv tawg?

Yog tias peb ua tib zoo saib qee cov rooj tog ntoo uas muaj qib siab, peb yuav pom tias feem ntau muaj qhov sib txawv ntawm ib sab ntawm cov rooj tog vaj huam sib luag.Qhov sib txawv no yog hu ua expansion joint lossis contraction joint. Nws tsis yog tshwm sim los ntawm kev ua yuam kev hauv rooj tog tsim thiab tsim khoom. Ntawm qhov tsis sib xws, cov pob qij txha nthuav dav yog cov "cov tswv yim" ntse rau lawv. Nws qhov muaj nyob tau ua lub luag haujlwm tseem ceeb hauv kev tswj cov yam ntxwv ntawm lub cev ntawm cov ntoo "kub nthuav dav thiab txias contraction" thiab txhim kho lub neej kev pab cuam ntawm cov rooj tog ntoo.

Vim li cas cov rooj tog ntoo muaj qhov sib txuas ntxiv?
Expansion sib koom ua ke yog ib hom kev siv tshuab ua haujlwm ntawm Suav classical rooj tog. Cov neeg uas muaj qee qhov kev paub txog cov rooj tog ntoo zoo paub tias cov rooj tog ntoo ntshiab huv yog ua kom khaws cov cuab yeej tsim khoom zoo ntawm Ming thiab Qing tsoos rooj tog - mortise thiab mortise qauv. Tsis siv tus ntsia thawv, cov khoom ntawm cov rooj tog sib dhos los ntawm kev sib xyaw ua ke ntawm mortise thiab mortise. Expansion pob qij txha yog siv los tiv thaiv lub thav duab los yog tenon ntawm cov rooj tog los ntawm kev tawg thaum ntoo shrinks los yog expands vim muaj kev cuam tshuam ntawm sab nraud ib puag ncig, uas ua rau lub loosening ntawm ntau yam ntawm cov rooj tog thiab tsis ua hauj lwm ntawm ib txwm siv.

Nws yog ib qho tsim nyog los kho qhov sib koom ua ke ntawm qhov chaw ntawm cov khoom siv ntoo. Nws yog hu ua art sewing lossis craft sewing. Feem ntau nyob rau hauv lub interface, thiab yog ob qhov sib txawv ntoo lis kev taw qhia!
Vim li cas cov rooj tog ntoo ntoo tawg?
1.Moisture cov ntsiab lus
Cov dej noo ntawm cov rooj tog ntoo tsis zoo tswj tau, thiab yuav muaj teeb meem zoo xws li tawg thiab deformation. Tom qab tsim cov rooj tog zaum, cov dej noo ntawm cov ntoo txiav txim siab seb cov duab thiab cov khoom ntawm cov rooj tog yuav hloov dua. Yog li ntawd, nws yog ib qho tseem ceeb heev los tswj cov dej noo ntawm cov rooj tog ntoo. Qhov sib npaug ntawm cov dej noo yuav tsis tawg thiab deform vim ib puag ncig yam xws li hnub ci, supercooling, overheating thiab lwm yam.
2.Txawm li cas los xij
Cov ntsiab lus noo noo ntawm rooj tog yog ib mus rau ob feem pua ????cov ntsiab lus qis dua qhov nruab nrab ntawm cov dej noo ntawm huab cua. Vim qhov sib txawv ntawm qhov chaw nyob, huab cua thiab huab cua hauv Suav teb kuj txawv, yog li cov dej noo cov ntsiab lus ntawm cov khoom ntoo rooj tog kuj txawv. Piv txwv li, qhov nruab nrab noo noo txhua xyoo ntawm Beijing yog 11.4%, yog li cov dej noo ntawm cov rooj tog ntoo yuav tsum tau tswj ntawm 10.4% lossis 9.4%; Qhov nruab nrab noo noo ntawm huab cua nyob rau sab qab teb yog 14%, thiab nyob rau sab qaum teb yog 12% mus rau 13%. Yog li ntawd, qee cov rooj tog ntoo nyob rau sab qab teb yuav tawg tom qab thauj mus rau sab qaum teb.
3. Kev thauj mus los
Nyob rau hauv kev thauj mus los ntawm cov rooj tog zaum, nws yog ib qho tsim nyog yuav tsum muaj pob thiab pob. Tsis tas li ntawd, vim kev nyab xeeb, kev thauj mus los ntawm cov rooj tog ntoo yog qhov nyuaj dua. Txawm hais tias cov rooj tog ntoo muaj zog dua lwm cov ntaub ntawv, nws yog ib qho nyuaj rau kev ciaj sia tsis muaj kev saib xyuas zoo.
