Reinforced rebar thiab vuam mesh tswj qhov sib tsoo dav ntawm cov av tsis muaj txheej txheem.
Feem ntau ntawm cov plag tsev hauv pem teb tsis ua kom muaj kev kho kom zoo, lossis tsuas yog ua cov kev txhim kho uas tsis muaj npe txhawm rau txhawm rau tswj qhov dav ntawm cov kab nrib pleb. Thaum ua kom muaj zog rebar tso rau hauv qhov chaw siab lossis sab saum toj ntawm cov pem teb tuab, nws tuaj yeem txwv qhov dav ntawm cov khoom sib tsoo los ntawm cov pob zeb ua pob zeb tawg, kev kub ntxhov, lub hauv paus qis, thau sab nraud, thiab lwm yam teeb meem.
Hom kev ua kom zoo dua no feem ntau hu ua lub shrinkage thiab ntsuas cov khoom kub.
Yuav luag txhua txheej av ua kom tsis txhob ua kom muaj zog, lossis tsuas yog ua qhov kev txhim kho uas tsis muaj npe txhawm rau txhawm rau tswj qhov dav ntawm cov kab nrib pleb.
Thaum lub rebar tau muab tso rau hauv qhov chaw sab saud lossis sab saum toj ntawm cov pem teb tuab, qhov dav ntawm cov khoom siv sib tsoo los ntawm cov pob zeb ua pob zeb tawg, kev kub ntxhov, lub hauv paus qis, lub nra ntim sab nraud, thiab lwm yam teeb meem tuaj yeem txwv. Hom kev ua kom zoo dua no feem ntau hu ua lub shrinkage thiab ntsuas cov khoom kub.
Cov hauv paus ntsiab lus
Txij li muaj ntau txoj kev xaiv txhim kho rau cov av tsis muaj txheej txheem hauv cov av, cov tshooj no yuav hais txog kev tswj cov kab nrib pleb los ntawm kev txhawb nqa thiab kev txhim kho mesh.
Reinforced rebar thiab vuam mesh tsis tiv thaiv kev tawg. Ua ntej pob zeb ua kom tawg, txoj haujlwm ntawm kev ua kom zoo li lub hauv paus yog dormant.
Thaum tawg tau tshwm sim, txoj haujlwm raug qhib thiab nws qhov dav yog tswj los ntawm kev txwv kev txhim kho ntawm qhov tawg. Yog tias cov pob zeb ua pob zeb pua pua rau hauv cov qib siab ua haujlwm zoo thiab ua kom muaj kev txhawb nqa zoo, thaum siv cov khoom siv pob zeb qis, qhov chaw khi raug teeb tsa li ntawm 4.5 metres lossis tsawg dua thiab txhim kho kom raug, feem ntau tsis tas yuav ua ntsuas kev txhim kho. Nyob rau hauv dav dav, muaj me me random los yog tsis-xaws kev tawg. Yog tias kev tawg ntom ntom ntom tshwm sim, qhov dav dav yuav tsum tau khaws cia me dua vim tias kev sib raug zoo ntawm qhov sib khi me me thiab qhov qis qis rau cov khoom siv pob zeb, yog li zam qhov teeb meem ntawm kev kho dua tshiab lossis kev saib xyuas.
Thaum qhov no tshwm sim, ntug ntawm qhov tawg tau tawg thiab ntug yuav tawg, tshwj xeeb tshaj yog thaum cov pob zeb hlais pob zeb yog tsoo los ntawm cov log, tshwj xeeb tshaj yog cov qib siab sib tsoo nrog lub log nyuaj.
Thaum qhov tshwm sim ntawm pob tawg tshwm sim, qhov dav dav ntawm qhov chaw yuav nce ntxiv thiab qhov puas ntawm pob zeb pob zeb tawg raws qhov chaw tawg yuav piam zuj zus tuaj. Kev txiav tawm thiab tuaj yeem txhim kho qhov siab yog qhov tsim nyog thaum shrink seams tsis tso cai hauv qhov chaw thiab tsis ntsia. Qee lub sij hawm hom no tseem hu ua kev txhim kho tsis tu ncua los yog cov npoo av tsis zoo, uas tso cai rau muaj ntau ntawm cov khoom muag nruj nreem (90 txog 180 cm) cov kab nrib pleb me me.
Cov hau kev ntawm kev tswj kom tawg
Feem ntau, nws muaj 2 txoj hauv kev los tswj kev sib tsoo:
(1) txhawm rau tswj qhov chaw ntawm qhov tawg los ntawm kev txhim kho lub ntsej muag ntsws me me (tsis muaj kev tswj hwm qhov dav ntawm qhov tawg), lossis
(2) txhawm rau tswj qhov dav dav los ntawm txhim kho qhov cuab yeej kho kom zoo dua qub (tswj tsis tau ntawm lub luag haujlwm). Txoj Kev 1, peb tuaj yeem tswj qhov chaw ua kom tawg ntawm cov pob zeb ua kev sib tsoo, qhov dav ntawm txoj kab shrink los yog lub ntsej muag tawg nyob rau hauv lub npoo yog feem ntau tswj los ntawm seam qhov nrug thiab pob zeb shrinkage. Raws li txoj leeg nqaws thiab pob zeb shrinkage nce, yog li puas muaj cov leeg dav. Zoo ib yam li cov kab nrib pleb, yog tias cov npoo dav dav ze rau ntawm 0.9 hli, qhov kev ua haujlwm ntawm cov xauv thiab ua kev thauj khoom ntawm cov khoom sib dhos thiab zam kev txav ntsug ntawm cov nqaws yog txo tsawg.
Nrog rau qhov no hauv siab, ntau tus neeg tsim qauv siv load conduction tsim xws li quab yuam qev, quab yuam hloov xa mus, lossis txuas ntxiv txuas ntxiv hauv qhov chaw khov kho kom paub tseeb tias qhov kev thauj khoom tau zoo thiab txwv txiav tawm ntsug ntawm cov nqaws. Txoj kev 2, peb tso cai rau cov pob zeb ua kev txawb pob zeb kom tawg kom nrawm, tab sis siv cov hlau tsis muaj zog lossis welded mesh kom tswj tau qhov dav tawg. Feem ntau, hom no tsis yog siv thaum teeb tsa lub nqaws. Kev nrib pleb tshwm sim ntau, tshwm sim me me, sib tawg. Vim tias qhov zoo li tau txiav txim siab pom, hom kev sib tsoo tswj hom yuav tsum sib txuas lus nrog tus tswv ua ntej.
