Mashoko ekuti F1, F2, uye F3 anoreva kupatsanurwa kwemafomu zvichienderana nekusimba kwavo kwakanyanya kunobvumirwa kana paine kongiri itsva. Sisitimu iyi inobva kumitemo yeGerman ( DIN 18218 ) asi inoshandiswa zvakanyanya pasi rose kuona kuchengetedzeka uye kushanda zvakanaka mukuvaka kongiri.
Heino kupatsanurwa kwemhando yega yega:
Misiyano Yakakosha: F1 vs. F2 vs. F3 Formwork
| mamiriro | F1 Formwork | F2 Formwork | F3 Formwork |
|---|---|---|---|
| Max Pressure | ≤ 30 kN/m² (≈ 4,350 psf) | ≤ 60 kN/m² (≈ 8,700 psf) | ≤ 100 kN/m² (≈ 14,500 psf) |
| Fresh Concrete Pressure | Kumanikidza kwakaderera | Kumanikidza kwepakati | Kumanikidza kwakanyanya |
| Dururira Rate & Hurefu | Zvishoma nezvishoma anodira (semuenzaniso, madziro <2m/awa) |
Kudira zvine mwero (semuenzaniso, madziro 2–4m/awa) |
Fast anodira (semuenzaniso, madziro> 4m/awa) |
| Tembiricha Sensitivity | Yakakosha (inononoka kuseta) | eresera | Yakaderera (kukurumidza kuseta) |
| Yakajairika Kushandisa Nyaya | Madziro matete, makoramu madiki, mapurojekiti mashoma-bhajeti | Madziro akaenzana, matanda, mbiru dzakasimukira | High-rise cores, silos, mapurojekiti ekuvaka nekukurumidza |
| Engineering Focus | Deredza kukurumidza kudira | Balance kumhanya & kuchengeteka | Gadzirisa nguva dzekutenderera |
Zvinhu Zvakakomba Zvinokurudzira F-Kirasi Sarudzo
- Duru Rate:
- Kukurumidza kudururira → yakakwira mvura yekumanikidza → inoda yakakwira F-kirasi.
- Kutya:
- Kutonhora kwemamiriro okunze kunononoka kugadzika kongiri → kudzvanywa kunovaka kureba → kunoda yakakwirira F-kirasi.
- Concrete Mix:
- Fluid mixes (high slump) inopa dzvinyiriro yakawanda kupfuura misanganiswa yakaoma.
- Element Geometry:
- Marefu, matete madziro (semuenzaniso, elevator cores) inoda F2/F3; slabs angangoda F1 chete.
Mienzaniso Inoshanda
- F1:Inoshandiswa kune isina kudzika nheyo, slabs, kana madziro madiki ekugara akadururwa zvishoma nezvishoma.
- F2:Yakajairika kumadziro mazhinji / makoramu muzvivakwa zvekutengesa.
- F3:Yakakosha kune yakakwirira-inokwira tower cores, mabhiriji piers, kana maindasitiri silos ane nekukurumidza kuisa kongiri.
Kuchengetedza & Kuteerera
- F-kirasi ratingsDzivirira kutadza kweformwork (njodzi huru yekuchengetedza) nekuenzanisa simba reformwork kune inotarisirwa kumanikidzwa kongiri.
- Mainjiniya ezvimiro anoverengera inodiwa F-kirasi zvichibva pazvirongwa zvekudira, ambient tembiricha, uye kongiri zvivakwa.
💡 Zano reUnyanzvi: Gara uchitsanangura zvinodiwa neF-class mumadhirowa ekuvaka. Kushandisa formwork isina kutarisirwa zvakanaka (semuenzaniso, F1 pabasa reF3) kunogona kukuvadza zvikuru!
Mazuva ano modular masisitimu (semuenzaniso, PERI, Doka) anowanzo takura F2/F3 ratings kutsigira mapurojekiti anomhanya-mhanya, nepo echinyakare fomu rematanda rinogona kuganhurirwa kuF1.
Uri kutsvaga mugadziri wemafomu muChina here?
TSX Groupe inogadzira masisitimu esimbi ekugadzira mapuranga (mhando dzemadziro, slab, column uye box culvert) uye inoatumira kunze kwenyika nehurongwa hwekurodha magaba uye magwaro akazara ekutumira kunze kwenyika. Ona chimiro chemutengesi nemapeji ezvinotsanangurwa pazasi:
- Mugadziri wesimbi uye mutengesi wefomu resimbi muChina — mhando dzemasystem, saizi dzepaneru uye ruzivo rwekubatanidza.
- Mugadziri & mutengesi weScaffolding muChina — masisitimu ekukiya nekuvhara macuplock emapurojekiti akafanana.
- Mugadziri wesimbi inogadziriswa muChina — kushongedza nekugadzira mapuranga kuti zvienderane nehurongwa hwema formwork ako.
