Nyob rau tib lub sijhawm, cov ntaub thaiv npog tau yooj yim ntsia rau hauv kab rov tav thiab ntsug.
Rau kev tsim kho ntawm lub hauv paus lossis phab ntsa nrog qhov tseeb geometry, nws yooj yim dua los siv cov vaj huam sib luag loj, thiab thaum txhim kho cov khoom siv vaj tsev, nws yog qhov zoo dua los muab kev nyiam rau cov vaj huam sib luag me me.
Koj kuj yuav tsum tau txiav txim siab txog cov khoom uas yuav ua rau tus ncej.
YPlastic formwork
Tshem tawm cov thav duab ua los ntawm cov khoom siv hluavtawstau txais koob meej vim lawv lub teeb yuag thiab yooj yim ntawm kev siv. Yas vaj huam sib luag formwork yog ib lub teeb yuag, uas muaj cov ntawv me me ntsuas 1210 x 605 mm. Koj tseem tuaj yeem tuav lawv lub installation ib leeg.
Tsis tas li ntawd, cov tshuab no muaj qhov zoo hauv qab no:
- nrog cov latches tshwj xeeb;
- UV thiab corrosion resistant yas;
- kev hloov pauv ntawm cov khoom lag luam no yog 100 npaug;
- yoojyim tshem tawm vim pob zeb tsis lo rau ntawm qhov chaw du ntawm cov laug cam;
- tsis xav tau lubrication ntxiv ua ntej siv.
Yog tias koj npaj yuav ua ib lub tsev siab txog 3 m, ces xws li vaj huam sib luag formwork rau phab ntsa yuav yog qhov kev xaiv zoo tshaj plaws.
ntoo formwork
Qhov no yog tus qauv pheej yig tshaj plaws uas koj tuaj yeem ua rau koj tus kheej yooj yim. Nws raug tso cai siv cov ntaub ntawv improvised, tab sis nws yog qhov zoo dua los mloog cov lus qhia ntawm cov kws tshaj lij. Rau cov ntoo vaj huam sib luag formwork, nws raug nquahu kom siv softwood lumber. Txawm li cas los xij, nws yog qhov pheej yig dua tsis yog los npaj cov panels los ntawm ob peb lub rooj tsavxwm, tab sis mus yuav cov ntawv npaj ua plywood (nyiam dua varnished).
Kev hloov pauv ntawm cov ntoo formwork tsis ntau tshaj 30 zaug. Txawm li cas los xij, yog tias peb tab tom tham txog kev tsim kho ntiag tug, qhov no yuav ntau tshaj qhov txaus.
steel formwork
Hlau vaj huam sib luag formwork muaj ntau yam zoo. Nws yog qhov tsim nyog thiab ruaj khov tshaj plaws. Cov ntawv hlau yog ua los ntawm cov hlau galvanized lossis galvanized.
Cov nplooj ntawv hlau tsis yog deformed thiab zoo txav deb ntawm cov pob zeb loj thaum lub sij hawm dismantling ntawm formwork.
Txawm li cas los xij, cov ntaub thaiv zoo li no muaj qee qhov tsis zoo. Piv txwv li, lawv hnyav heev, uas ua rau nyuaj heev rau cov txheej txheem ntawm kev tsim lub thav duab yam tsis tas siv cov cuab yeej tshwj xeeb. Tsis tas li ntawd, steel yog raug rau corrosion.
Aluminium Formwork
Aluminium hnyav dua li hlau. Tsis tas li ntawd, cov ntaub thaiv npog rau lub hauv paus, ua los ntawm cov ntawv zoo li no, yuav tsis xeb.
Ntawm cov minuses ntawm cov khoom siv no, nws tsim nyog qhia nws lub zog qis thiab poob ntawm cov duab geometric nyob rau hauv lub siab ntawm cov kua qhob mortar. Yog li ntawd, cov qauv no tsuas yog siv rau cov tsev me me thiab cov hauv paus. Rau kev tsim kho ntawm phab ntsa siab, nws yog qhov zoo dua los xaiv cov khoom siv txhim khu kev qha.
