Ib qho ntawm cov kev tsim qauv txhim khu kev qha tshaj plaws rau kev tsim cov hauv paus rau cov tsev thiab cov qauv yog lub hauv paus monolithic pob zeb. Txhawm rau kom nws cov kev ua tau zoo nyob rau hauv cov nqe lus ntawm lub zog thiab tsis kam mus rau ntau yam loads, nws yog ntxiv nrog hlau reinforcing tawb.
Hauv cov tsev uas tsis muaj hauv qab daus, sab trench phab ntsa yog siv los ua formwork. Tab sis nws yuav tsum tau muab sau tseg tias nyob rau hauv no technology ntawm kev ua hauj lwm, ib tug nce noj ntawm cov pob zeb yog pom, uas yog economically unprofitable. Ib qho kev txhim kho zoo thiab ruaj khov formwork yuav txo qhov poob ntawm cov pob zeb sib xyaw, nrog rau txhim kho cov tuab ntawm cov qauv, uas yuav tsum tau ua los ntawm kev tsim cov duab kos rau lub hauv paus monolithic.
Kev teeb tsa ntawm formwork panels ua los ntawm cov ntoo coniferous yog nqa tawm ntawm cov xuab zeb cushion.
Cov ntoo tawv tuaj yeem siv rau kev kho cov ntsiab lus. Raws li kev siv tshuab, qhov dav ntawm cov laug cam rau kev tsim cov ntaub thaiv npog yuav tsum tsis pub tshaj 150 millimeters. Boardsyuav tsum yog tib lub thickness. Qhov saum npoo ntawm daim thaiv nyob rau hauv kev sib cuag nrog pob zeb yog them nrog ib tug polyethylene zaj duab xis los yog sheathed nrog tin. Nws yog txwv tsis pub siv formwork panels uas muaj qhov sib txawv ntawm cov laug cam kom tsis txhob ntws ntawm cov cement laitance.
Lub hauv paus monolithic yog txhawb ntxiv nyob ntawm qhov muaj peev xwm ntawm cov av ntawm nws lub hauv paus. Rau zus tau tej cov reinforcing thav duab, kub dov rebar ntawm ib ntus profile yog siv. Rau txhua tus neeg siv lub tawb nqa khoom hauv qhov project, qhov loj, hom thiab txoj kab uas hla ntawm cov cuab yeej siv tau raug qhia. Yog hais tias txoj kab uas hla ntawm ib tus pas nrig yog txog li 25 hli, lawv tau muab khi rau hauv ib lub thav duab nrog cov xov hlau tshwj xeeb, qhov chaw vuam lossis yas fasteners, yog tias ntau tshaj 25 hli, ces siv hluav taws xob arc vuam.
Tam sim ntawd ua ntej nchuav lub hauv paus monolithic, lub formwork yuav tsum tau ntxuav cov txheej ntawm cov av, cov khib nyiab, thiab qhov cuab lub zog yuav tsum tau ntxuav ntawm xeb. Cov qhov khoob yuav tsum tau kho.
Kev ua haujlwm pob zeb suav nrog cov haujlwm thev naus laus zis hauv qab no: kev tsim khoom thiab xa cov pob zeb sib xyaw rau hauv qhov chaw, nws tso rau hauv daim ntawv thiab kev saib xyuas thaum lub sijhawm teeb tsa. Lub hauv paus monolithic ua tau raws li nws cov kev ntsuas tsis tsuas yog tias nws yog ua los ntawm cov pob zeb zoo sib xyaw. Nws qhov zoo nyob ntawm ntau yam: hom cement, aggregates, dej thiab ntau lwm yam. Lub hauv paus monolithic daim kab xev yog concreted nyob rau hauv ib tug tas mus li txoj kev, tab sis nyob rau hauv thaum muaj xwm ceev, txoj kev no yuav ua taucuam tshuam nrog lub obligatory ntaus ntawv ntawm kev ua hauj lwm seams. Kev ua haujlwm seams tsuas yog ua los ntawm kab rov tav lossis ntsug, nws yog nruj me ntsis txwv tsis pub ua kom lawv inclined. Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws thaum ua cov hauv paus monolithic, nws yog ib qho tsim nyog yuav tsum tau co lub pob zeb sib tov.
