Mawu akuti F1, F2, ndi F3 amatanthauza magulu a formwork kutengera kukana kwawo kwakukulu kovomerezeka pamene muli konkriti yatsopano. Dongosololi limachokera ku miyezo ya ku Germany ( DIN 18218 ) koma limagwiritsidwa ntchito kwambiri padziko lonse lapansi kuti zitsimikizire chitetezo ndi magwiridwe antchito pomanga konkriti.
Nayi chidule cha mtundu uliwonse:
Kusiyanitsa Kwakukulu: F1 vs. F2 vs. F3 Formwork
| mbali | F1 mawonekedwe | F2 mawonekedwe | F3 mawonekedwe |
|---|---|---|---|
| Max Pressure | ≤ 30 kN/m² (≈ 4,350 psf) | ≤ 60 kN/m² (≈ 8,700 psf) | ≤ 100 kN/m² (≈ 14,500 psf) |
| Kupanikizika Kwatsopano Konkriti | Zovuta | Kuthamanga kwapakatikati | Kuthamanga kwakukulu |
| Thirani Mtengo & Kutalika | Pang'onopang'ono kuthira (mwachitsanzo, makoma <2m/ola) |
Kuthira kwapakati (mwachitsanzo, makoma 2-4m/ola) |
Kuthamanga mofulumira (mwachitsanzo, makoma> 4m/ola) |
| Kutentha Kwambiri | Zovuta (zolowera pang'onopang'ono) | Wongolerani | Pansi (zosintha mwachangu) |
| Nthawi Zogwiritsa Ntchito | Makoma owonda, mizati yaing'ono, ntchito zochepa za bajeti | Makoma okhazikika, mizati, mizati yapakatikati | Ma cores okwera kwambiri, ma silo, ntchito zomanga mwachangu |
| Engineering Focus | Chepetsani kuthamanga | Kusamalitsa liwiro & chitetezo | Konzani nthawi yozungulira |
Zinthu Zovuta Zomwe Zimayambitsa Kusankhidwa Kwamagulu a F
- Mtengo Wothira:
- Kuthira mwachangu → kuthamanga kwambiri kwamadzimadzi → kumafuna gulu la F apamwamba.
- Kutentha:
- Kuzizira kumachepetsa konkriti → kukanikiza kumamangika motalikirapo → kumafuna gulu la F apamwamba.
- Konkire Mix:
- Kusakaniza kwamadzimadzi (kutsika kwakukulu) kumapereka mphamvu zambiri kuposa zosakaniza zolimba.
- Element Geometry:
- Makoma amtali, owonda (mwachitsanzo, ma elevator cores) amafuna F2/F3; ma slabs angafunike F1.
Zitsanzo Zothandiza
- F1:Amagwiritsidwa ntchito ngati maziko osaya, ma slabs, kapena makoma ang'onoang'ono okhalamo amathiridwa pang'onopang'ono.
- F2:Muyezo wa makoma ambiri / mizati m'nyumba zamalonda.
- F3:Ndikofunikira pakumanga nsanja zazitali, ma milatho, kapena ma silo a mafakitale okhala ndi konkriti mwachangu.
Chitetezo & Kugwirizana
- F-class ratingspewani kulephera kwa formwork (chiwopsezo chachikulu chachitetezo) pofananiza mphamvu za formwork ndi kukakamiza konkriti komwe kumayembekezeredwa.
- Akatswiri opanga zomangamanga amawerengera kalasi ya F yofunikira potengera mapulani, kutentha kozungulira, ndi konkriti.
💡 Malangizo Abwino: Nthawi zonse tchulani zofunikira za gulu la F muzojambula zomanga. Kugwiritsa ntchito mawonekedwe osayenerera (monga F1 pa ntchito ya F3) kungawononge kwambiri!
Makina amakono amakono (mwachitsanzo, PERI, Doka) nthawi zambiri amakhala ndi mavoti a F2/F3 kuti athandizire mapulojekiti othamanga, pomwe matabwa achikhalidwe amatha kukhala F1.
Mukufuna wopanga mafomu ku China?
TSX Groupe imapanga makina opangira zitsulo (mitundu ya khoma, slab, mzati ndi bokosi) ndipo imatumiza kunja ndi mapulani oyika ziwiya ndi zikalata zonse zotumizira kunja. Onani mbiri ya ogulitsa ndi masamba ofotokozera pansipa:
- Wopanga ndi wogulitsa mafomu achitsulo ku China — mitundu ya makina, kukula kwa mapanelo ndi tsatanetsatane wa kulumikizana.
- Wopanga ndi wogulitsa ma scaffolding ku China — makina otsekera ndi otsekera a mapulojekiti omwewo.
- Wopanga zitsulo zosinthika ku China — kuyika ndi kukongoletsa kuti zigwirizane ndi kapangidwe kanu ka formwork.
