Kev xaiv lub tshuab ua formwork zoo yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm kev tsim kho, qhov zoo ntawm cov qauv, kev tswj tus nqi, thiab kev ruaj khov. Raws li kev coj ua thoob ntiaj teb thiab kev paub txog kev tsim kho hauv Suav teb, cov lus qhia hauv qab no piav qhia txog cov kev xav tseem ceeb rau kev xaiv cov formwork zoo tshaj plaws.
1. Sib phim cov khoom siv formwork rau hom project
daim ntawv
| Hom Hom | Hom Formwork uas pom zoo | Kev ua phoojywg |
|---|---|---|
| Cov tsev nyob siab / cov tsev txheem | Aluminium alloy formwork | Kev hloov pauv ntau (200–300 lub voj voog), lub sijhawm voj voog sai (4–5 hnub/hauv pem teb), qhov sib koom ua ke tsawg, ua tiav cov pob zeb zoo dua, tsis tas yuav siv zog ua haujlwm ntau rau kev teeb tsa rov ua dua. |
| Cov choj txuas, cov thawv girders | Cov hlau ua haujlwm | Muaj peev xwm thauj khoom tau zoo (> 60 kN / m²), tiv taus kev cuam tshuam zoo heev, ruaj khov nyob rau hauv qhov siab siab thiab cov dej ntau. |
| Cov qauv geometries / architectural forms uas nyuaj | Cov ntoo sib xyaw ua ke | Muaj peev xwm hloov kho tau yooj yim heev—tuaj yeem txiav, khoov, lossis ua duab rau cov kab nkhaus, cov domes, thiab cov khoom tsis yog tus qauv; zoo tagnrho rau cov khoom ntim tsawg, cov khoom ua raws li tus qauv. |
| Cov chaw tsim khoom lag luam / phab ntsa txheem | Yas / yas-hlau formwork | Qhov chaw du, tsis tas yuav siv cov tshuaj tso tawm, yooj yim ntxuav, txo cov nqi tiav tom qab nchuav rau hauv phab ntsa thiab slab rov ua dua. |
| Cov phiaj xwm ntsuab / cov pa roj carbon tsawg | Magnesium alloy formwork | Sib dua li txhuas 30%, muab cov khoom siv hauv tsev 100% hauv Suav teb, cov pa roj carbon tsawg tshaj plaws ntawm cov hlau xaiv. |
2. Kev Txiav Txim Siab Matrix: Kev Ua Tau Zoo Sib Piv
daim ntawv
| Kauj | Hlau Formwork | Aluminium Alloy Formwork | Cov Qauv Ntoo | Cov Khoom Siv Yas | Magnesium Alloy Formwork |
|---|---|---|---|---|---|
| Thawj Nqi | High | Siab (tab sis qis amortization) | Tsawg | Medium | Nruab Nrab–Siab (qis dua ntawm qhov ntsuas) |
| Cov voj voog tig rov qab | 40-80 | 200-300 | 30-50 | > 250 | |
| Nyhav | 40-60 kg/m² | 15-20 kg/m² | 10-15 kg/m² | 8-12 kg/m² | 12-16 kg/m² |
| Installation Ceev | Qis (yuav tsum tau crane, cov neeg ua haujlwm txawj) | Siab (20–30 m²/tus neeg/hnub) | Nruab Nrab (yooj yim txiav, tab sis cov pob qij txha muaj ntau) | Siab (sib dua, sib dhos sai) | Siab (kev sib xyaw ua ke, kev sib dhos tsawg kawg nkaus) |
| Qhov Zoo ntawm Cov Pob Zeb | Zoo (yuav tsum muaj txheej tiv thaiv xeb) | Zoo heev (du, tsis muaj honeycomb) | Ncaj ncees (yooj yim rau kev hloov pauv los ntawm cov dej noo) | Zoo heev (tsis lo, tsis tas yuav ntxuav) | Zoo heev (rigidity siab, thermal expansion tsawg) |
| Ib puag ncig cuam tshuam | Recyclable, tab sis siab zog | 100% rov ua dua tshiab, cov pa roj carbon tsawg | Siv cov ntoo, tus nqi rov ua dua tshiab <10% | Siv tau dua tshiab (qee qhov muaj PVC) | Cov khoom siv hauv tsev ntsuab uas tau los ntawm hauv tebchaws |
| Zoo Tshaj Plaws Rau | Ntev ntev, cov khoom hnyav, cov choj | Cov tsev siab, cov phab ntsa txiav, cov plag tsev txheem | Cov haujlwm me me, cov qauv ib ntus, cov duab tsis sib xws | Cov chaw tsim khoom, phab ntsa hauv qab nthab | Cov tsev siab, cov tsev ntsuab, kev tsim kho ua ntej |
Lus Cim: Cov ntaub ntawv tau los ntawm kev ntsuas hauv kev lag luam thiab cov ntaub ntawv txog kev siv tshuab. Cov nqi tiag tiag yuav txawv ntawm cov chaw tsim khoom thiab cov txheej txheem tsim kho.
3. Cov Ntsiab Cai Xaiv Tseem Ceeb (Kev Xyaum Tshwj Xeeb rau Tuam Tshoj)
- Kev hloov pauv huab cuaHauv cov cheeb tsam ntug dej hiav txwv uas muaj av noo, tsis txhob siv cov ntoo formwork vim yog o thiab deformation; nyob rau hauv cov cheeb tsam txias sab qaum teb, xaiv cov hlau lossis txhuas rau kev tiv taus khov-thaw.
- Kev Txhim Kho Kev Ua Lag LuamRau cov haujlwm uas siv sijhawm ntau tshaj 6 lub hlis lossis nrog ntau dua 10 lub plag tsev rov ua dua, xaiv cov txheej txheem siab-cycle (txhuas lossis magnesium alloy) kom txo qis tus nqi amortized.
- Kev Ua Haujlwm Ua Haujlwm: Hauv cov cheeb tsam uas muaj kev tsis txaus neeg ua haujlwm, cov qauv txhuas thiab yas txo qhov kev vam khom rau cov tshuab hnyav thiab txiav cov nqi ua haujlwm los ntawm 30-40%.
- Kev Ua Kom Tiav Zoo: Rau cov pob zeb uas raug nthuav tawm (architectural), xaiv cov txheej txheem uas muaj kev ruaj khov siab—txhuas lossis hlau—kom ntseeg tau tias cov pob qij txha nruj, tsis muaj kev sib dhos tsis sib xws, thiab tsis muaj xau.
- Kev Ruaj Ntseg ntawm Cov Khoom Siv: Tuam Tshoj muab ntau tshaj 70% ntawm cov peev txheej magnesium thoob ntiaj teb. Cov hlau nplaum magnesium sib haum nrog lub teb chaws "kev ncig sab hauv" thiab "ob chav carbon", tau txais kev txhawb nqa txoj cai muaj zog.
4. Kev Hloov Pauv Tshiab: Kev Sawv Ntxov ntawm Magnesium Alloy Formwork
Cov hlau nplaum magnesium formwork tab tom hloov zuj zus los ntawm lwm txoj hauv kev mus rau qhov kev daws teeb meem zoo dua, tsav los ntawm:
- Lub Hnav Tsim UaQhov ceev ntawm 1.74 g/cm³—30% sib dua li txhuas—ua kom kev tuav tau zoo dua txog li 40%.
- Kev xeb thiab kev ruaj khovKev tiv thaiv alkali zoo dua ua rau lub neej ua haujlwm ntev dua 250 lub voj voog, ua tau zoo dua li cov yas thiab cov hlau ib txwm muaj.
- Kev Sib Koom Ua Ke Die-Casting: Tshem tawm cov ntsiab lus vuam, txhim kho kev ruaj khov ntawm cov qauv thiab txo cov nqi kho los ntawm 50%.
- Strategic Advantage: Cov khoom siv hauv tsev tag nrho hauv Suav teb ua kom muaj kev ywj pheej tiv thaiv kev cuam tshuam cov khoom siv thoob ntiaj teb thiab txhawb nqa cov lus txib kev tsim kho kom ruaj khov.
