3. Formwork laying qauv:
Cov ntoo square uas haum ze rau lub formwork yuav tsum tau muab tso rau lengthways. Board pob qij txha me me li sai tau, nruab nrab ntawm lub rooj tsavxwm thiab lub rooj tsavxwm kom tiaj tus. Board sib txuas nrog tus kheej-nplaum daim kab xev.
a.Sab saum toj pwm:
Firstly, nteg ntoo square ntawm scaffolding kab rov tav nrog qhov sib nrug ntawm li 1.2m, ces nteg ntoo square nrog qhov sib nrug ntawm tsis ntau tshaj 200-300 hli, thaum lub thickness ntawm lub pouring tshaj 200 hli, qhov sib nrug yuav tsum tau kho kom haum.
b. Phab ntsa pwm:
longitudinally nteg square ntoo tom qab formwork,qhov nrug yog 150-200mm. nyob rau hauv kab rov tav nteg ob square ntoo txuas, tawm zoo los ntawm phab ntsa ntsia hlau txoj hauj lwm, teem zoo kab pheeb ces kaum bracing, transversal muaj steel flute kev twb kev txuas muaj pes tsawg leeg hom loj phab ntsa pwm, tuaj yeem ncaj qha lifted, kuj tuaj yeem raug tshem tawm thiab hloov ib daim formwork..
c.Beam, kab pwm:
txiav tawm cov qauv raws li qhov loj me, sab saum toj nyob ntawm phab ntsa ntsia liaj qhov rooj txoj hauj lwm, kem pwm muaj scaffolding plaub sab xauv, teeb tsa kab pheeb ces kaum zoo.
Cov ntsiab lus muaj zog rau cov yas formworks.
1. Txuag haujlwm thiab sijhawm
Qhov saum npoo ntawm cov khoom yog ze li huv si thiab huv si, thiab lub splicing ntawm formwork yog nruj thiab du.
Tom qab demolding, qhov degree ntawm qhov chaw thiab ua tiav ntawm cov pob zeb ua tiav tshaj qhov kev xav tau ntawm cov dej ntshiab uas twb muaj lawm, yog li tsis tas yuav tsum tau plastering theem nrab, txuag kev ua haujlwm thiab cov khoom siv.
2. Lub teeb thiab yooj yim rau nruab
Yas tsev formwork tsis yog tsuas yog lub teeb thiab yooj yim rau nruab, tab sis kuj muaj zog adaptability rau cov txheej txheem.
Nws tuaj yeem raug ntsia, sawed, shaved, drilled, tsis tawg, tsis deformed, tsis tas yuav kho thiab tu. Nrog cov khoom siv tuaj yeem tsim los ntawm cov duab geometric, kom ua tau raws li qhov xav tau ntawm ntau yam duab ntawm kev txhawb nqa kev tsim vaj tsev.
3. Yooj yim demould
Qhob tsis-stick pwm nto, tsis xav tau kev tso tawm tus neeg sawv cev, yooj yim rautso tawm, yooj yim los ntxuav cov plua plav.
4. Kub kub kuj
Lub zog txhua yam, tsis muaj shrinkage, tsis ntub nthuav dav, tsis muaj cracking, tsis deformation, seem stability, alkali tsis kam thiab corrosion kuj, nplaim retardant thiab waterproof, nas thiab kab resistant nyob rau hauv qhov kub thiab txias ntawm -20 degree rau ntxiv 60 degree .
5. Zoo zog thiab rigidity
Nyob rau hauv ob qhov taw qhia ntawm kev cuam tshuam lub zog thiab khoov degree, nws tau dhau deb tshaj cov plywood.
6.Law kos
Lub sijhawm rov siv dua ntawm cov qauv siv yas tuaj yeem ncav cuag li 30 zaug,no yooj yim thermal expansion thiab contraction, piv rau ntoo formwork.
7. Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob
Khib nyiab formwork thiab trimmings tuaj yeem rov ua dua tshiab, tsis muaj kuab paug pov tseg.
8.Cov khoom lag luam raug nqi
15mm yas tsim qauv 150 yuan /pcs(recycling 35 yuan /pcs, qhov tiag 115 yuan /pcs) tuaj yeem siv 30 zaug, txhua zaus tus nqi xav tau 3.83 yuan.
14 hli ntoo formwork 60 yuan /pcs(tsis tuaj yeem rov ua dua), tuaj yeem siv tau 6-8 zaug, txhua zaus tus nqi ntawm 8.57 yuan.
