Qhov tshwm sim ntawm theem tseem ceeb tshaj plaws ntawm kev ua haujlwm ua haujlwm nyob ntawm cov khoom siv zoo, yog li ntawd, cov ntaub ntawv tsim nyog nrog kev teeb tsa thev naus laus zis.
Ua haujlwm nrog formwork: cov lus pom tseem ceeb
- Qhov sib txawv ntawm kev npaj tsim qauv yuav tsum tsis pub ntau tshaj 2 hli;
- Qhov tsis zoo rau Formwork, feem ntau yuav ua rau lub nra ntawm cov pob zeb sib xyaw, lossis hauv qee qhov chaw nws yuav ploj mus ntawm daim ntawv npaj npaj;
- Ua ntej yuav mounting cov formwork, qhov saum npoo uas nws yuav tau mounted, nws yog qhov tsim nyog yuav tsum tau dlhos;
- Txhim kho cov qauv formwork yuav tsum tau ua siv cov ntsiab lus tshwj xeeb;
- Qhov khoob ntawm cov ntaub thaiv yuav tsum tsis pub ntau tshaj 2 hli.
Cov ntaub ntawv rau cov qauv formwork
Daim formwork tuaj yeem tsim los ntawm yuav luag txhua yam uas muaj. Feem ntau cov feem ntau nws yog ua los ntawm cov ntoo ntoo lossis cov laug cam dog dig. Ntxiv mus, tom kawg yuav siv ob qho tib si edged thiab unedged. Tsis ntev los no, yas formwork yog nce tau mounted. Nws muaj tus nqi qis. Lwm qhov kev xaiv yog cov ntawv txheeb ntawm noo noo tiv taus lossis cov plywood downwood.
Txhawm rau txhim kho tag nrho cov qauv, zoo li rau kev sib txuas Plywood cov ntawv siv siv cov laug cam. Kev txhom tau teeb tsa qhov twg koj yuav tsum tau sib dhos ib hom formwork. Qhov ntau xws li kev mus ncig ua si, zoo dua cov formwork yuav tiv thaiv lub siab ntawm cov pob zeb ua.
Cov hom formwork
Tsuas muaj ob hom formwork: bent thiab tshem tau. Thawj qhov kev pom yuav siv tau ib zaug xwb. Tom qab tag nrho, tom qab qhob tawv tawv, cov formwork hloov mus rau hauv chav ua haujlwm ntawm cov chaw tiav.Cov formwork ntawm daim ntawv thib ob tuaj yeem siv ntau zaus, txij li tom qab kev ruaj khov ntawm cov kev daws teeb meem, cov formwork yog dismantled. Raws li qhov tshwm sim, kev ua haujlwm kev ua haujlwm yuav pheej yig dua.
Siv tau
Cov ntaub ntawv no yog pawg neeg thoob tebchaws. Raws li txoj cai, nws muaj polystyrene ua npuas ncauj los yog daim hlau sib txuas los ntawm cov dhia thiab muaj lub tsev fuabtais grooves. Qhov no ua kom pom tseeb ntawm cov formwork. Daim phiaj lawv tus kheej yog lub teeb zoo nkauj - tsis muaj ntau tshaj li 1.5 kg. Lawv sab hauv qab yog ntxeem tau, uas muab qhov zoo tshaj plaws tuav nrog pob zeb tuav.
Qhov no yog qhov tsim qauv zoo uas tsim daim foos uas yuav tsum tau ua. Raws li qhov tshwm sim, nws muab:
- tiv thaiv cov pwm thiab sab nraud ib puag ncig;
- Rwb thaiv tsev kom sov sov thiab waterproofing.
Tshem tau
Daim foos txiav tawm tau tuaj yeem muab tso los ntawm cov khoom sib txawv.
- Cov thaiv. Cov qauv no tau txais txiaj ntsig kom faib cov ntawm lwm tus nrog nws tus nqi qis.
- Yas. Rau formwork, cov panels yog siv los ntawm cov polymer, thiab qee zaum hauv lem mus thiab cov fiberglass. Cov thaiv hniav yog txhim kho los ntawm cov hlau hlau.
- Chipboard nrog rau hlau thav duab. Cov khoom nws tus kheej ua rau nws yooj yim xaiv cov qauv xav tau loj.
- Edged Board. Los ntawm nws koj tuaj yeem sau cov ntaub thaiv ntawm ntau qhov ntau thiab tsawg.
Qhov kev txhawb nqa no yog yooj yim heev rau mount. Txawm li cas los xij, nws yog ib qho tseem ceeb kom ua raws li kev ua ntu zus. Txhawm rau pib nrog, nws yuav tsum tau tso qhov chaw ua haujlwm, rub tawm cov trench lossis qhov chaw rau lub hauv paus ntawm lub foundation. Tom qab ntawd nws yog qhov tsim nyog los ua qhov kawg markup thiab mount lub ntsiab lus txuas ntxiv. Tom qab koj tuaj yeem txav mus rau txoj kev nce ntawm cov formwork nws tus kheej.
Los ntawm plywood lossis Edged cov laug cam sua cov ntaub thaiv ntawm qhov loj me. Tom qab ntawd txheej ntawm polyethylene tau txuas rau sab hauv ntawm txhua daim ntaub thaiv lossis tso pa tshuab siv. Yog tias qhov no tsis tau ua tiav, tom qab ntawd ua kom qhuav, cov kev daws teeb meem yuav lob nrog plywood lossis cov laug cam, thiab rov qab ntxuav.
Txhawm rau kom muaj cov duab geometry ntawm lub hauv paus, nws raug nquahu kom rub lub lace thiab twb teeb block lossis thaiv.
Cov phab ntsa ntawm cov kev tshem tawm tsim kho cov ntoo tuav. Ntxiv nrog rau kev faib ua formwork, koj tuaj yeem siv vuam. Rau qhov no, nyob ntawm txoj kab feem ntawm kev txhawb nqa hauv cov shields ua los ntawm cov ntoo, parallel qhov nrog txoj kab uas hla ntawm 8 txog 10 hli yog qhov drilling. Lawv ntxig qhov cuab lub zog thiab ntxeem rau nws weld lwm qhov ntawm kev txhawb, uas haum kom nruj rau cov formwork thaiv. Yog li, los ntawm cov sib txawv ntawm cov formwork yuav tsum yog lub t-cov duab t-duab, uas yuav ua kom lub siab ntawm cov pob zeb sib xyaw.
Nyob rau hauv cov npaj ua formwork, qhob los ntawm cov sib tov yuav tsum tau nchuav tusyees. Nws yog qhov tsis tsim nyog tau hliv nws rau hauv ib qho chaw. Nyob rau tib lub sijhawm, nws yog qhov tsim nyog ua raws li tus cwj pwm ntawm cov formwork: Yog tias peb pom tias nws txiav nws, thiab cov zajlus tau txhawb. Tshem tawm cov qauv ua haujlwm siv rau hnub thib ob thib peb tom qab sau.
Tsab ntawv xov xwm tau luam tawm hauv phau ntawv ceev "cov lus qhia ntawm cov tub txawg" No. 3 (2019). Koj tuaj yeem sau npe yuav cov luam tawm ntawm kev tshaj tawm.
