Kev tsim kho cov ntaub ntawv pob zeb, rau nws cov khoom tshwj xeeb yog dav siv los tsim lub tsev.Nws yuav tsum tau nchuav rau hauv cov pwm tsim tshwj xeeb, uas yog hu ua formwork lossis shuttering.
Formwork tuav lub poured pob zeb nyob rau hauv cov duab kom txog rau thaum nws hardens thiab ua tiav lub zog txaus los txhawb nws tus kheej thiab cov qauv khoom hnyav.Formwork tuaj yeem faib ua ntau txoj hauv kev:
- Los ntawm cov ntaub ntawv
- Los ntawm qhov chaw siv
Formwork muaj lub luag haujlwm tseem ceeb hauv kev tsim vaj tsev.Nws yuav tsum muaj lub zog txaus los nqa tag nrho cov khoom tam sim no thaum lub sijhawm ua haujlwm casting, thiab yuav tsum tuav nws cov duab thaum lub pob zeb ua kom tawv.
Dab tsi yog Qhov Yuav Tsum Tau Ua Zoo Formwork?
Txawm hais tias muaj ntau cov ntaub ntawv formwork, cov hauv qab no yog cov kev ua haujlwm dav dav kom tau raws li qhov xav tau ntawm kev tsim vaj tsev:
- Muaj peev xwm dais hnyav loads.
- khaws nws cov duab nrog kev txhawb nqa txaus.
- Pob zeb tawg-pov thawj.
- Qhob tsis puas thaum tshem cov formwork.
- Cov khoom siv tuaj yeem rov siv dua thiab rov ua dua tom qab lub neej ntev.
- lub teeb
- Cov ntaub ntawv formwork yuav tsum tsis txhob sib hloov lossis distort.
Hom formwork los ntawm cov khoom:
Ntoo Formwork
Ntoo formwork yog ib qho ntawm thawj hom formwork puas tau siv.Nws yog sib sau ua ke ntawm qhov chaw thiab yog hom yoog raws tshaj plaws, kho tau yooj yim.Nws Qhov Zoo:
- Yooj yim tsim thiab tshem tawm
- Lub teeb, tshwj xeeb tshaj yog thaum piv nrog hlau formwork
- Ua haujlwm tau, tso cai rau txhua yam duab, qhov loj me thiab qhov siab ntawm pob zeb ua qauv
- Kev lag luam hauv cov haujlwm me me
- Tso cai siv cov ntoo hauv zos
Txawm li cas los xij, tseem muaj qhov tsis txaus:nws muaj lub neej luv luv thiab siv sijhawm ntev hauv cov haujlwm loj.Feem ntau, cov ntoo formwork raug pom zoo thaum cov nqi ua haujlwm tsawg, lossis thaum cov pob zeb ua haujlwm nyuaj yuav tsum tau hloov pauv, kev tsim qauv tsis rov ua dua ntau.
Plywood Formwork
Plywood feem ntau yog siv nrog ntoo.Nws yog cov khoom siv ntoo tsim, uas muaj nyob rau hauv ntau qhov sib txawv thiab thicknesses.Nyob rau hauv daim ntawv thov formwork, nws yog tsuas yog siv rau sheathing, decking thiab daim ntawv linings.
Plywood formwork muaj cov khoom zoo sib xws li ntoo formwork, nrog rau lub zog, durability thiab ua lub teeb yuag.
Hlau Formwork:Hlau thiab Aluminium
Steel formwork tau dhau los ua neeg nyiam vim nws lub neej ua haujlwm ntev thiab ntau yam rov siv dua.Txawm hais tias nws kim heev, steel formwork yog qhov muaj txiaj ntsig zoo rau ntau qhov haujlwm, thiab nws yog qhov kev xaiv siv tau thaum muaj ntau lub sijhawm rau kev rov siv dua.
Cov hauv qab no yog qee qhov tseem ceeb ntawm steel formwork:
- Muaj zog thiab ruaj khov, nrog lub neej ntev
- Tsim ib tug du tiav ntawm pob zeb nto
- Waterproof
- Txo cov nyhuv honeycombing hauv pob zeb
- Yooj yim nruab thiab dismantled
- Haum rau cov qauv nkhaus
Aluminium formwork zoo ib yam li steel formwork.Qhov sib txawv tseem ceeb yog tias aluminium muaj qhov ntom ntom dua li cov hlau, uas ua rau cov qauv sib zog.Aluminium kuj muaj lub zog qis dua hlau, thiab qhov no yuav tsum tau txiav txim siab ua ntej siv nws.
Plastic Formwork
Hom formwork no yog sib sau ua ke los ntawm kev sib cuam tshuam cov vaj huam sib luag lossis cov tshuab modular, ua los ntawm cov yas uas muaj zog thiab muaj zog.Plastic formwork ua haujlwm zoo tshaj plaws hauv cov haujlwm me me uas muaj cov haujlwm rov ua dua, xws li cov vaj tsev nyob qis.
Yas formwork yog lub teeb thiab tuaj yeem ntxuav nrog dej, thaum tsim nyog rau cov ntu loj thiab ntau yam rov qab siv dua.Nws qhov teeb meem tseem ceeb yog muaj qhov hloov pauv tsawg dua li cov ntoo, vim tias ntau cov khoom yog prefabricated.
Kev faib tawm Formwork Raws li cov qauv tsim
Ntxiv nrog rau kev faib tawm los ntawm cov khoom siv, formwork kuj tseem tuaj yeem raug cais raws li lub tsev tsim kev txhawb nqa:
- Phab ntsa formwork
- Kem formwork
- Slab formwork
- Beam formwork
- Foundation formwork
Txhua hom formwork yog tsim raws li cov qauv uas lawv txhawb nqa, thiab cov kev npaj tsim kho tau hais txog cov ntaub ntawv thiab cov thickness uas yuav tsum tau ua.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev tsim kho formwork yuav siv sij hawm, thiab nws tuaj yeem sawv cev ntawm 20 thiab 25% ntawm cov nqi tsim khoom.Txhawm rau txo tus nqi ntawm formwork, xav txog cov lus pom zoo hauv qab no:
- Cov phiaj xwm tsim tsev yuav tsum rov siv cov khoom tsim thiab cov duab geometry kom ntau li ntau tau kom tso cai rov siv dua.
- Thaum ua hauj lwm nrog ntoo formwork, nws yuav tsum tau txiav mus rau hauv pieces uas loj txaus yuav rov qab siv dua.
Cov vaj tse sib txawv hauv kev tsim thiab lub hom phiaj.Zoo li hauv feem ntau qhov kev txiav txim siab, tsis muaj kev xaiv zoo dua li qhov seem rau txhua daim ntawv thov;qhov zoo tshaj plaws formwork rau koj qhov project txawv nyob ntawm seb lub tsev tsim.
