Hloov qhov kub, av noo, huab cua feem ntau, seismic thiab dynamic loads yog yam uas feem ntau ua rau cov qauv deformation. Yog li ntawd qhov kev hloov pauv ntawm cov khoom siv hauv tsev (kev nthuav dav lossis kev cog lus vim qhov sib txawv ntawm qhov kub thiab txias) lossis cov khoom tawg (vim yog qhov yuam kev hauv kev suav ntawm lub hauv paus lossis tsis txaus ntseeg ntawm av) tsis ua rau kev puas tsuaj ntawm tag nrho cov qauv, nws yog. pom zoo kom siv kev sib koom ua ke.
Yam kev sib koom tes
Nyob ntawm seb hom deformation yuav tsum tau tiv thaiv, cov pob qij txha sib txawv ntawm qhov kub thiab txias, shrinkage, anti-seismic thiab sedimentary.
Kev sib koom ua ke yog siv los tiv thaiv kab rov tav hloov. Thaum xam ib lub tsev lag luam nrog cov txheej txheem txheej txheem, cov seams nyob tsawg kawg yog txhua txhua 60 m rau cua sov thiab 40 m rau cov tsev tsis muaj cua sov. Raws li txoj cai, cov pob qij txha txuas ntxiv cuam tshuam rau cov txheej txheem saum toj no hauv av, thaum lub hauv paus tsis tshua cuam tshuam los ntawm qhov kub thiab txias.
Qhov kev daws teeb meem sib koom ua ke yog qhov tsim nyog txhawm rau txhawm rau tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb hauv cov txheej txheem raws li qhov tseeb tias cov khoom thauj tsis sib npaug lossis cov av tsis muaj zog thiab qee cov ntsiab lus sag. Tsis zoo li qhov kub thiab txias seam, cov seam sedimentary kuj cais lub hauv paus.
Kev tiv thaiv seismic expansion pob qij txha hauv cov tsev nyob hauv thaj chaw uas muaj kev nce seismic yog qhov tsim nyog. Ntawm lawv cov nqi, lub tsev tau muab faib ua cov blocks uas tseem ceeb ntawm kev ywj pheej ntawm ib leeg, thiab yog li ntawd, thaum muaj av qeeg, kev puas tsuaj lossis deformation ntawm ib lub thaiv yuav tsis cuam tshuam rau lwm tus.
Yog tias koj cov qauv muaj cov cam khwb cia-hauv-situ reinforced pob zeb phab ntsa, yuav tsum muaj kev sib koom ua ke sib txuas. Qhov tseeb yog tias cov pob zeb ua rau me me thiab me me - uas yog, phab ntsa nchuav ncaj qha rau ntawm qhov chaw tsim kho, thiab tsis sib sau los ntawm cov pob zeb ua vaj tse, yuav txo qis hauv ntim, tsim qhov sib txawv. Rau qhov yooj yim ntawm kev ua hauj lwm ntxiv, lub shrinkage seam yog ua ua ntej pouring phab ntsa tom ntej, thiab tom qab cov pob zeb dries, cov seams thiab qhov khoob raug kaw.
sealing thiab insulating seams
Qhov no yog qhov tseem ceeb heev uas yuav tsum tau ua tib zoo saib xyuas: cov seams yuav tsum muaj kev tiv thaiv zoo los ntawm lwm yam. Rau qhov no, ntau hom rwb thaiv tsev thiab muab tub lim yog siv. Polyurethane los yog epoxy sealants yog ib qho kev xaiv zoo: lawv muaj siab hardness thiab tsis hloov tau yooj yim; Lwm qhov kev xaiv -
sivpolyethylene ua npuas ncauj hlua, ua raws li kev sib khi nrog sealant. Lwm qhov kev xaiv yog sau cov expansion sib koom ua ke nrog cov ntxhia wool. Thiab lub expansion sib koom ua ke nyob rau hauv lub phab ntsa, uas muaj cov ntxhia wool, yuav tsum tau muab kaw nrog ib tug elastic pawg uas yog resistant rau huab cua tej yam kev mob thiab tiv thaiv lub muab tub lim los ntawm ya raws thiab dampness. Ntxiv nrog rau cov fillers, cov seam tuaj yeem tiv thaiv nrog ib qho profile lossis plank ntawm qhov loj me.
Seam sizes
Qhov dav ntawm cov pob qij txha nthuav dav txawv ntawm 0.3 cm mus rau 100, nyob ntawm seb hom kev sib koom ua ke, nrog rau kev ua haujlwm ntawm lub tsev. Cov pob qij txha txuas mus txog 4 cm (nqaim), thiab cov pob qij txha shrinkage yog nruab nrab (4-10 cm) thiab dav (10-100 cm).
