Txhua lub tsev xav tau lub hauv paus ruaj khov. Hauv kev tsim kho tus kheej, pawg-kab kab xev thiab kab xev yog feem ntau. Tib txoj hauv kev los tsim ib daim ntawv rau lub hauv paus ntawm lub tsev yog feem ntau ntawm kev tsim cov formwork. Hauv cov txheej txheem, cov ntaub thaiv npog yog siv.
Qhov tsis zoo tshaj plaws ntawm kev tsim qauv yog deformation ntawm cov laug cam nyob rau hauv lub siab ntawm cov tshuaj. Txawm li cas los xij, niaj hnub no muaj cov ntaub ntawv tshiab ntawm kev ua lag luam uas tso cai rau koj los hloov cov laug cam thiab daws qhov teeb meem no. Yog li ntawd, daim ntawv plywood yog siv. Nws raug nqi ntau dua li cov phiaj, tab sis muaj ntau yam zoo.
Vim li cas thiaj xaiv plywood
Plywood formwork muaj ntau qhov zoo, ntawm lawv yuav tsum tau qhia:
- evenness thiab smoothness ntawm cov khoom;
- moisture resistance;
- easy installation;
- tsis tshua muaj yuav warp;
- txo nqi zog.
Thaum lub sijhawm txheej txheem casting, plywood tuaj yeem khaws nwscov khoom vim muaj dej tsis kam. Koj tuaj yeem nruab nws tus kheej. Cov ntsiab lus yuav tsis deform thaum sau. Yog tias peb piv cov plywood nrog cov ntoo boards, ces thawj tus yog ntsia nrog tsawg lub sij hawm.
Xaiv plywood
Yog tias koj xav tsim plywood formwork, ces ua ntej koj yuav tsum xaiv cov khoom. Yog tias nws tsis tau npaj rov siv dua, nws yog qhov zoo dua los yuav cov ntawv laminated. Tus nqi ntawm ib tug yuav nyob ntawm 560 txog 1200 rubles. Qhov sib txawv no muaj feem xyuam rau cov tuam txhab thiab cov yam ntxwv.
Cov khoom siv zoo laminated plywood yog cov txheej txheem ntau txheej, uas yog npog nrog cov yeeb yaj kiab polymer ntawm ob sab. Nws yog resistant rau ya raws thiab mechanical kev nyuaj siab. Cov khoom siv hauv tsev no yog qhov ruaj khov tshaj plaws ntawm lwm hom plywood, xws li FK thiab FSF.
Koj tuaj yeem yuav khoom tshiab lossis siv tau. Hauv thawj kis, peb tab tom tham txog laminated plywood 18 mm, uas tuaj yeem siv txog li 100 zaug. Yog tias cov canvases tau ua haujlwm hnyav, ces lawv cov kev hloov pauv tau txo mus txog 70 zaug. Los ntawm kev yuav khoom siv, koj tau txais lub sijhawm los siv nws txog 55 zaug. Cov peev txheej raug tshuaj xyuas los ntawm kev sim thiab cuam tshuam rau tus nqi kawg. Txhua yam uas hais txog yuav muaj txaus los nteg daim kab xev.
Ua ntej koj tsim plywood formwork, koj tuaj yeem xav txog lwm txoj kev daws teeb meem. Piv txwv li, ntau yam ntaub ntawv cim FK yog cov ntawv uas tau ua nrogsiv urea kua nplaum. Nws muaj ntau ntawm formaldehyde resins. Yog li ntawd, cov plywood no tsis haum rau cov qauv ruaj khov.
Cov boards no yog cov dej tsis muaj zog, thiab lawv cov kev tiv thaiv kom ya raws yog qis dua li cov plywood laminated. Txawm li cas los xij, nrog kev siv ceev faj, kev hloov pauv ntawm FC nce mus txog 25 zaug. Cov khoom no raug nqi mus txog 1950 rubles. ib daim ntawv.
Rau qhov tsim ntawm FSF plywood, formaldehyde nplaum yog siv. Nws muab cov nplooj ntawv muaj zog thiab tiv thaiv kom ya raws. Cov yeeb yaj kiab no tau ntsib plywood 18 hli tau txhim kho kev hnav tsis kam. Lub turnover ncav cuag 43 lub sij hawm. Nws yog raws li ib tug nplaum muaj pes tsawg leeg, uas, nyob rau hauv tus ntawm noo noo thiab kub, pib tso phenol. Koj tuaj yeem siv hom ntawv no nkaus xwb rau kev ua haujlwm sab nraum zoov. Rau 1 daim ntawv ntawm FSF koj yuav tau them 2800 rubles.
Plywood formwork yuav muaj FBK. Nyob rau hauv cov ntaub ntawv no, peb tab tom tham txog daim hlau, cov khaubncaws sab nraud povtseg yog interconnected los ntawm ib tug lacquered bakelite muaj pes tsawg leeg, resistant rau ya raws thiab tsis ntshai ntawm kub hloov. Cov ntaub yog khov kho tiv thaiv huab cua thiab huab cua. Qhov no plywood yog noo noo resistant, thiab nws tus nqi nce mus txog 3500 rubles. ib daim ntawv. Nws tuaj yeem siv tau rau txhua qhov kev ua haujlwm.
Ib qho piv txwv ntawm kev hnav tsis kam thiab lub zog txhua yam yog Finnish plywood nrog FB cim, uas yog siv nyob rau hauv tej yam kev mob nrog high humidity. Qhov kev daws teeb meem tshaj plaws yog FBS nplooj ntawv. Lawv yog ua los ntawm veneer, uas yog ua tiav nrog cawv-raws li bakelite kua nplaum. Yog li ntawd, nws yog qhov ua tau kom tau txais cov kab mob microorganism-resistant webs uas muaj peev xwmtiv taus kab rov tav thiab ntsug loads.
8mm plywood yog cov khoom siv thinnest. Ntawm kev muag khoom koj tuaj yeem nrhiav 15 mm nplooj ntawv. Tus nqi kawg yuav nyob ntawm tus yam ntxwv ntawm lub hauv paus. Muaj cov kua nplaum nyob rau hauv cov khaubncaws sab nraud povtseg, uas muab cov plywood cov cuab yeej ntawm yooj. Cov khoom siv hauv tsev muaj lub zog khoov siab. Tus nqi ntawm ib daim ntawv nce mus txog 3800 rubles.
Cov lus qhia
Ua ntej txhim kho cov ntawv ntawm 8 hli plywood, nws yog ib qho tsim nyog los npaj ib lub trench, sib sib zog nqus mus rau tus nqi xam. Yog hais tias nws yog npaj los txhim kho ib pawg-kab kab xev hauv paus, nws yuav tsum tau tho qhov dej raws hauv qab ntawm lub trench. Cov tom kawg yog rov ntxuav, thiab tom qab ntawd ib txheej ntawm xuab zeb yog nchuav rau hauv qab, uas yuav tsum tau compacted. Qhov saum npoo yog kuaj nrog qib.
Kev txhim kho plywood
Cov dej-resistant formwork plywood yuav tsum muab tso rau ntawm ob sab ntawm lub trench. Cov khaub ncaws yuav tsum nyob ib ncig ntawm lub perimeter thiab hauv qab cov kabmob. Txhawm rau kom tsis txhob txav mus los, fastening yog nqa tawm nrog spacers, braces thiab jumpers. Cov nplooj ntawv yog txuas rau ib leeg nrog steel pins. 10 hli qhov yog drilled hauv plywood rau qhov no. Cov phab ntsa ntawm lub qhov yog npog nrog cov roj kom qhuav kom tsis txhob ya raws nkag mus.
Ib lub raj yas corrugated yog muab tso rau nruab nrab ntawm cov nplooj ntawv raws qhov dav ntawm trench. Txhawm rau kom phim qhov kev ncua deb ntawm cov nplooj ntawv, cov ntoo thaiv yog ntsia. Thaum disassembling cov qauv, cov studs raug tshem tawm ntawm lub raj. Tus pin yog muab tso rau hauv lub qhov thiab tsautxiv ntseej. Sab phab ntsa yog ntxiv dag zog nrog cov ntsia hlau ntsia hauv peb kab. Ib lub qhov 10 hli yog drilled rau hauv txhua txoj kev tsheb ciav hlau.
Yuav ua li cas kom smoothness
Yog tias lub hauv paus npaj siab yuav tsum muaj lwm txoj kev tsheb ciav hlau yuav tsum nyob hauv qhov chaw. Staples yog tsau rau ntawm cov ces kaum sab nrog tus kheej tapping screws. Fasteners yuav tsum nyob rau sab nraud. Qhov no yuav xyuas kom meej lub smoothness ntawm sab hauv. Cov ntsia hlau yog hammered los ntawm sab hauv thiab khoov. Tag nrho cov kab nrib pleb raug kaw kom tsis txhob muaj cov pob zeb tawg. Txhawm rau tiv thaiv lub plywood los ntawm lub siab, clamps yog muab tso rau ntawm nws. Los ntawm sab nraud ntawm lub formwork, cov ceg txheem ntseeg tau tsav mus rau hauv av, uas tau rub ua ke nrog cov hlau los ntawm saum toj no.
Siv khib
Stands for formwork yog siv nyob rau hauv kev tsim kho ntawm ceilings siv monolithic technology. Nyob rau tib lub sijhawm, nws tuaj yeem ua haujlwm ntawm qhov siab txog li 5.5 m. Thaum tsim cov ceilings ntawm qhov siab siab, cov qauv siv telescopic yog siv. Yog tias cov khoom muaj txiaj ntsig zoo dua, koj yuav tsum siv lub kaw lus ntawm qhov ntim ntim rau kev ua haujlwm.
Nyob hauv kaw
Thaum txhim kho daim ntawv rau lub hauv paus, nws yuav tsum tau txiav cov nplooj ntawv. Rau qhov no, laser txiav tshuab yog siv. Qhov no tso cai rau koj los xyuas kom meej qhov nrawm ntawm kev ua haujlwm thiab pab kom ua tiav kev zoo nkauj. Ua-nws-koj tus kheej plywood txiav siv cov txheej txheem no yog tus cwj pwm los ntawm tus nqi qis thiab qhov raug siab. Qhov dav txiav yog qhov tsawg, thaum cov cuab yeej siv tau ntau yam.
