Kev tsim vaj tsev cib tseem nyob hauv nws qhov kev tsim kho. Cib tso yog tus yam ntxwv ntawm lub zog thiab ruaj khov. Lub zog ntawm cov masonry yog nws lub peev xwm los pom cov khoom xa los ntawm cov txheej txheem overlying. Nws yog cuam tshuam los ntawm qhov loj thiab cov duab ntawm cov ntaub ntawv masonry, qhov ntom thiab tuab ntawm cov pob qij txha mortar, hom ntawm cib thiab mortar. Thickness ntawm 10-15 mm rau longitudinal (kab rov tav) seams thiab 8-15 mm rau ntsug sawv daws yuav normalized.
Kev ruaj ntseg ntawm masonry yog nws lub peev xwm los tswj txoj haujlwm nyob rau hauv kab rov tav (piv txwv li, cua) loads, nws txwv qhov siab ntawm phab ntsa ua.
Cib tso rau sab nrauv ntawm phab ntsa yog ua los ntawm cov cib zoo siab, thiab sab hauv, cib nrog qhov tsis zoo, ib nrab yog siv. Cov khoom yog siv los ua cov khoom rov qab.
Yuav ua kom cov phab ntsa raug tsa ntsug, thiab cov seams - kab rov tav, txawm, siv fixtures - moring(stretched horizontally) thiab ordering (ntsia vertically, nyob rau hauv lub ces kaum). Tag nrho cov cib nteg yog nqa tawm nrog hnav khaub ncaws ntawm seams (kab thib ob pib nrog ib nrab cib). Qhov no tsis tsuas yog muab qhov zoo nkauj rau ntawm phab ntsa, tab sis kuj sib npaug faib cov khoom thauj. Lub sab nrauv ntawm cib nyob rau hauv phab ntsa yog ib tug verst, sab hauv kab yog backfill. Cib nteg yog tychkovy thiab diav. Hauv thawj kis, lub cib tau muab tso rau ntawm phab ntsa, hauv qhov thib ob - raws nws.
Hom cib tso: ib kab, peb kab, thiab ntau kab. Nyob rau hauv thawj rooj plaub, nrog ib tug ib-kab saw system, lub tsev cog khoom thiab diav kab alternate dressings. Vertical transverse seams yog offset los ntawm ib lub quarter ntawm cib, thaum longitudinal - los ntawm ib nrab. Xws li masonry yog ib qho yooj yim los ua, muaj zog, tab sis yog laborious.
Nrog peb-kab hnav khaub ncaws, peb kab ntawm rab diav hloov nrog ib txoj hlua khi. Transverse ntsug seams nyob rau hauv 3 kab uas nyob ib sab yog tsis bandaged. Hom masonry no yog siv rau hauv kev tsim cov piers txog li 1 m dav thiab ncej.
Multi-row system yog tus cwj pwm los ntawm poking kab los ntawm peb lossis tsib kab kab. Lub transverse ntsug seams ntawm kab ntawm bonders yog tsim nrog ib tug offset ntawm ib lub quarter ntawm ib tug cib, ntawm diav kab - los ntawm ib nrab ntawm ib tug cib. Longitudinal ntsug seams los ntawm 2nd mus rau 6th kab tsis yog bandaged. Multi-kab cib ua haujlwm ntau dua, tab sis tsis muaj zog.
Thawj theem ntawm kev thauj khoom masonry yog ib txwm siv los ntawm ntuj. Qhov thib ob theem ntawm kev thauj khoom ua rau cov tsos ntawm cov kab nrib pleb hauv ib tus neeg cib. Nyob rau theem pebntsug kab nrib pleb tsim, tab sis cov masonry tseem perceives sab nraud rog, ua, txawm hais tias nws twb xav tau kev kho dua.
Kev kho vaj tse pob zeb yog txuam nrog cov teeb meem xws li tawg cib, chipping ntawm cib, tsis ua hauj lwm ntawm cov pob qij txha. Yog tias cov kab nrib pleb me me, ces lawv tau nthuav dav me ntsis, ntxuav thiab ntim nrog kua cement mortar. Nyob rau hauv cov ntaub ntawv ntawm cov kab nrib pleb tseem ceeb, cov tshuaj yuav tsum thicker thiab nrog ntxiv ntawm cov kua nplaum. Qee zaum bricks crumble. Txhawm rau hloov (me me), lub mortar ntawm lub seam yog ua tib zoo khob tawm nrog ib tug chisel thiab rauj, cib, khib nyiab, av raug tshem tawm thiab cov cib zoo yog muab tso rau ntawm lub mortar tshiab. Txhawm rau kho cov seam, cov mortar qub uas siv tsis tau raug tshem tawm thiab hloov nrog ib qho tshiab.
