Tshem cov ntaub pua plag nyob rau lub sijhawm yog qhov tseem ceeb rau kev ua kom muaj kev ntseeg siab thiab tswj cov sijhawm. Tshem tawm lawv thaum ntxov ntxov tuaj yeem ua rau cov qauv tsis muaj zog thaum tawm ntawm lawv ntev dhau tuaj yeem ncua kev nce qib. Tawm tsam txoj cai yog qhov tseem ceeb rau kev nyab xeeb thiab txuag tau zoo.
Hauv qab no, peb tshawb lub hom phiaj ntawm cov pob zeb ua cov ntaub ntawv, cov lus qhia rau cov lus qhia tshem tawm, thiab cov lus qhia tswv yim los tiv thaiv kev ncaj ncees ntawm koj tus qauv raws li kev taug qab.
Lub Hom Phiaj ntawm Cov Pob Zeb Ua Si?
Qhob cov ntaub ntawv, paub tias yog formwork, yog pwm ib ntus uas tuav cov khoom ntab ntub hauv qhov chaw raws li nws kho. Lawv ua ib lub luag haujlwm tseem ceeb hauv kev ua luam thiab txhawb cov pob zeb ua kom txog thaum nws tawv tawv, ua kom muaj kev ruaj khov thiab qhov tseeb hauv kev tsim kho.
Cov ntsiab lus tseem ceeb ntawm formwork nrog:
Ua Rau Cov Pob Zeb: Kom paub qhov ntev thiab tsim qauv yog ua tiav.
Txhawb nqa cov qhob ntub dej: Tiv thaiv kev deformation lossis vau thaum lub sijhawm kho tus txheej txheem.
Kev ua kom muaj kev nyab xeeb: Stormilizes cov qauv qauv, tsim kom muaj kev nyab xeeb rau kev tsim kho.
Muab cov chaw du: Xa cov tiav kom huv, txo qhov xav tau ntawm kev kho tom qab kev tsim kho.
Daim formwork yog indispensable hauv kev tsim kho niaj hnub, los ntawm kab ntsug kom tav toj thiab cov qauv tsim.
Yuav ntev npaum li cas yuav pob zeb ua ua ntej tshem tawm cov formwork?
Lub sijhawm rau kev tshem cov vaj tse cov pob zeb nyob ntawm seb hom qauv thiab kho cov xwm txheej. Cov txheej txheem ntsug xws li phab ntsa thiab kab ntawv feem ntau yuav tsum muaj 16-24 teev ua ntej slabs thiab kab kab rov tav tej zaum yuav xav tau 7-14 hnub.
Ntawm no yog qhov tawg:
Ntsug qauv qauv(piv txwv li cov phab ntsa, kab ntawv): Cov foos feem ntau yuav raug tshem tawm tom qab 16-24 teev.
Kab rov tav qauv(xws li, slabs, kab teeb): slabs tuaj yeem stripped tom qab 7 hnub rau spans nyob rau hauv 4.5 meters lossis 14 hnub rau kev tshaj tawm ntev dua. Beams feem ntau yuav tsum tau 14 hnub.
Yam xws li kub, kho txoj kev, thiab pob zeb ua kom sib xyaw kom zoo rau cov sijhawm no. Kev sim ua kom muaj zog ua kom muaj kev nyab xeeb tshem tawm thiab tiv thaiv cov teeb meem qauv qauv.
Ua Daim Ntawv Formwork puas sab laug ntev dhau?
Thaum tawm daim ntawv nyob ntev dua li qhov tsim nyog yuav tsis ua mob rau cov pob zeb ua ke, nws tuaj yeem ua rau ntau yam teeb meem:
Qeeb: Lub caij nyoog ceev ceev tswj kev pab thiab nqes hav kev nce qib.
Cov teeb meem adhesion: Cov ntaub ntawv tuaj yeem ua rau cov pob zeb ua, ua rau tshem tawm kev nyuaj.
Nto puas: Ntau zog quab yuam thaum lub sij hawm ncua sij hawm tshem tawm tuaj yeem ua rau chipping lossis tsis sib xws.
Txhawm rau zam cov teeb meem no, ua rau pom zoo tshem tawm lub sijhawm thiab npaj ua tib zoo ua tib zoo sib npaug nrog cov phiaj xwm kev ua haujlwm.
Koj yuav paub li cas thaum pob zeb ua tau zoo?
Phab ntsa feem ntau tau txog kev kho tiav tom qab 28 hnub, tab sis lub zog muaj zog rau kev tshem tawm yog feem ntau ua tiav ntau dhau los. Cov cim tias kev npaj ua tiav rau daim ntawv tshem tawm muaj xws li:
Lub Zog Kev Tshuaj Ntsuam: Pob zeb yuav tsum ua tiav tsawg kawg 50-70% ntawm nws lub zog tsim.
Kev nyuaj: Cov saum npoo yuav tsum tawm tsam khawb lossis indentations.
Kev Saib Xyuas Kev Pom: Cov qhob yuav tshwm sim tshwm sim ruaj khov thiab pom tsis muaj cov cim ntawm kev tawg.
Kev kho cov kev coj ua zoo, xws li tswj kom ya raws thiab tswj qhov kub thiab ceev kev txhim kho lub zog thiab kom paub meej daim ntawv raug tshem tawm.
Yuav ua li cas koj tuaj yeem tiv thaiv Formwork los ntawm kev ua pob zeb ua?
Ua daim formwork tau tuaj yeem ua kev puas tsuaj rau ob lub pob zeb ua ke thiab cov ntawv no lawv tus kheej. Txhawm rau tiv thaiv qhov no, ua raws li cov kev coj ua zoo tshaj plaws:
Thov tso tawm cov neeg sawv cev:Siv roj-raws li kev tso tawm dej los yog tso tawm dej nyob rau hauv Formwork saum toj ua ntej tso pob zeb ua ntej.
Cov ntaub ntawv huv tsis tu ncua:Tshem tawm cov khib nyiab thiab cov seem tom qab siv los tswj cov chaw du.
Xyuas kom muaj formwork du:Tsis txhob teev lossis thaj chaw ntxhib uas tuaj yeem tuav cov qhob.
Tshem cov ntaub ntawv sijhawm:Sawb cov ntawv thaum cov pob zeb ua tiav tau zoo rau kev pheej hmoo ua kom muaj kev phom sij.
Cov kauj ruam no ua kom cov tshuaj tiv thaiv du, tiv thaiv cov pob zeb ua tiav, thiab ncua lub neej ntawm koj cov formwork.
