Hauv kev tsim kho niaj hnub no, laminated plywood rau formwork tau nquag siv. Nws yog qhov tsim nyog rau kev tsim kho ntawm ntau hom ntawm lub hauv paus. Nws lub neej kev pab cuam yog qhov siab heev, txij li qhov saum npoo yog tiv thaiv los ntawm noo noo los ntawm txheej tshwj xeeb. Cov khoom zoo tshaj plaws tuaj yeem tiv taus txog li 50 lub voj voog ntawm kev siv yam tsis muaj kev hloov pauv loj.

Cov khoom lag luam dav dav

Laminated plywood rau formwork yog tsim los ntawm cov ntoo nias. Cov khaubncaws sab nraud povtseg yog sib koom ua ke nrog cov nplaum nplaum. Acrylic lacquer yog siv rau qhov kawg ntawm cov laug cam los muab kev tiv thaiv ya raws. Ib zaj duab xis ntawm txaus ntom yog siv rau saum. Kev tsim cov thev naus laus zis cuam tshuam rau qhov kub thiab txias.

Qhov zoo ntawm kev siv cov khoom

Txij li laminated plywood rau formworkmuaj cov dej noo zoo thiab cov yam ntxwv muaj zog txaus, sib haum rau cov ntsiab lus ntawm GOST, nws lub sijhawm ua haujlwm ntev heev. Cov phenolic zaj duab xis ntawm qhov chaw tiv thaiv cov khoom los ntawm UV hluav taws xob.

Cov nplooj ntawv yooj yim txiav txawm tias ua haujlwm nrog cov cuab yeej tes. Studs, ntsia hlau los yog tus kheej tapping screws tuaj yeem siv los ua fasteners. Vim muaj cov yeeb yaj kiab tshwj xeeb, cov pob zeb sib xyaw tsis lo rau saum npoo ntawm cov slabs.

Kev faib tawm los ntawm cov yam ntxwv zoo

Nyob ntawm qib, laminated plywood rau formwork tuaj yeem muaj tus nqi sib txawv. Txhua pawg tso cai rau qee qhov tsis zoo. Muaj plaub hom khoom nyob rau hauv tag nrho:

1. Kev tsis tuaj yeem ua tiav.
2. Muaj wormholes thiab intergrown knots uas kaw nrog veneer inserts.
3. muaj qhov thiab hollows.
4. Ntawm qhov chaw muaj ntau yam kev phem ntau yam.

Qhov zoo ntawm cov boards txhim kho nrog qib nce. Lawv lub zog kuj ua tau zoo dua, uas muaj txiaj ntsig zoo rau kev pabcuam lub neej. Cov khoom uas tsis muaj pob tw thiab wormholes yuav siv tau ntev dua.

Laminated plywood rau formwork: daim ntawv qhov ntev

Thaum nchuav cov hauv paus, 18 hli tuab slabs feem ntau yog siv, vim lawv lub zog yog qhov siab heev, thiab tus nqi yog qhov txaus. Hais txog qhov dav thiab ntev, cov nplooj ntawv ntawm 300x150, 250x125 thiab 244x122 cm yog ntau dua.

Qee lub tuam txhab tsim cov khoom ntawm lwm qhov ntev, tab sis lawv tsis tshua siv los ua formwork. Txhua qhov ntau thiab tsawg tau pom yog tib hom thiab tsis txawv ntawm qhov ua tau zoo lossis lub cev muaj zog.

Bearing thav duab

Ua ntej laminated formwork plywood tuaj yeem ntsia tau, cov qauv kev txhawb nqa yuav tsum tau txhim tsa uas tuaj yeem txhawb nqa cov pob zeb sib xyaw. Feem ntau, cov txheej txheem hlau hlau yuav suav nrog:

• cov boards uas muaj kwv yees li qhov ntev tib yam li cov ntawv sheathing;
• cov ntsiab lus siv rau kev teeb tsa ntawm tus ncej tav;
• universal barriers rau tsim kab;
• telescopic ncej nruab nrog lub thawv rau kev tsim cov plag tsev.

Yog tias tsim nyog, cov ntoo thaiv ntawm qhov tsim nyog tuaj yeem siv rau lub cuab yeej ntawm lub hauv paus ncej. Txawm li cas los xij, nrog kev ua haujlwm tsis tu ncua ntsig txog kev tsim kho ntawm lub hauv paus, nws yog qhov zoo dua los yuav cov hlau thaiv tshwj xeeb.

Laminated khoom lag luam

Cov ntaub ntawv ntawm kev siv ntau yam ntaub ntawv yuav luag txhua qhov tsis sib xws. Txawm li cas los xij, nws yuav tsum tau hais tias qhov kev hloov pauv ntawm laminated plywood formwork tuaj yeem ncav cuag 50 lub voj voog, uas suav tias yog qhov txiaj ntsig zoo. Qhov no ua tau yog tias cov khoom lag luam los ntawm cov tuam txhab European tau yuav.

Raws li kev lag luam Lavxiascov khoom zoo sib xws, nws yog sawv cev los ntawm ntau lub npe. Txawm li cas los xij, lawv cov yam ntxwv zoo yog qis dua cov analogues los ntawm Tebchaws Europe. Feem ntau, cov khoom siv hauv tsev tuaj yeem tiv taus tsis pub dhau 20 lub voj voog ntawm kev siv raws li tus qauv.

Qee zaum pheej yig zaj duab xis ntsej muag plywood yog siv rau formwork. Tuam Tshoj yog nws cov khoom tseem ceeb. Feem ntau, cov khoom zoo li no yuav siv tsis tau tom qab 5 lub voj voog. Txawm li cas los xij, nrog kev siv tsis tu ncua, lub neej ntawm cov khoom siv tau txo qis, tsis hais tus neeg tsim khoom.

Nyob rau hauv xaus txog cov yam ntxwv ntawm kev saib xyuas

Thaum ntsia, laminated plywood rau formwork yog raug rau lub tsev sib tov uas muaj ib tug npaum li cas ntawm cov dej, abrasives thiab active additives. Yog hais tias lub txheej muaj peev xwm tiv taus cov teev sab nraud, ces sab hauv tsis yog. Qhov kev phom sij tseem ceeb nyob rau hauv kev puas tsuaj rau lub laminated nto, raws li cov channel qhib kom nqus dej noo.

Koj tuaj yeem zam qhov kev puas tsuaj ntawm txheej tiv thaiv nrog kev ua tib zoo tuav cov khoom thaum lub sijhawm ua haujlwm. Tom qab tshem tawm cov nplooj ntawv, kev tu ncua sij hawm ntawm qhov chaw los ntawm kev sib kis yuav tsum tau nqa tawm. Ua ntej lub sijhawm ntev cia, nws raug nquahu kom lubricate cov phaj nrog cov neeg ua haujlwm tshwj xeeb. Qhov no yuav txhim kho kev tiv thaiv dej.

Ceev faj ntawm cov khoom siv tsuas yog xav kom cov neeg ua haujlwm saib xyuas kev ua haujlwm ib txwm ua. Cov ntawv plywood yuav tsum tau muab tso rau ntawm qhov npajnto tsis muaj protruding rau tes thiab lwm qhov chaw nrog ntse kawg. Thaum txhim kho fasteners, yuav tsum tau saib xyuas kom tsis txhob ua rau cov txheej txheem puas.
