1. Nnua a Wɔde Yɛ Nnua: Nnua a wɔde yɛ nneɛma yɛ kɔnkrit a wɔde yɛ nneɛma a wɔde di dwuma wɔ amanne kwan so na wɔtaa de di dwuma no mu biako. Wɔde nnua te sɛ pine ne fir titiriw na ɛyɛ, na ɛwɔ mfaso horow te sɛ emu duru a emu yɛ hare, ɛnyɛ den sɛ wɔbɛyɛ, na ɛho ka sua. Nnua a wɔde yɛ nneɛma no fata ma kɔnkrit adan a ne nsusuwii ne ne kɛse gu ahorow, titiriw adan a ɛyɛ kurukuruwa anaasɛ ɛnyɛ pɛpɛɛpɛ. Nanso, nnua a wɔde yɛ adwuma no ntumi ntra hɔ kyɛ yiye na ɛyɛ mmerɛw sɛ nsu, nsɛe, na ɛporɔw, enti mpɛn pii no ɛfata ma nnwuma a ɛyɛ bere tiaa anaa nea ɛho nhia pii.
2. Dade Formwork: Wɔde dade na ɛyɛ dade formwork na ɛwɔ su ahorow a ɛyɛ den kɛse, ɛyɛ den yiye, na ɛyɛ den kɛse. Ɛfata ma kɔnkrit adan akɛseɛ, emu yɛ duru, anaa ɛkyɛ{2}}te sɛ abɔntenban ne adan a ɛkorɔn-ɔsoro. Wobetumi asan de dade a wɔde yɛ adwuma no adi dwuma mpɛn pii, na ɛtew adwuma no ho ka so. Bere koro no ara mu no, dade a wɔde yɛ adwuma no ani a ɛyɛ tratraa kɛse no hwɛ hu sɛ kɔnkrit dan no te sɛ nea ɛyɛ fɛ. Nanso, dade a wɔde yɛ adwuma no mu yɛ duru, na ɛma wɔbɔ ka kɛse wɔ akwantu ne nneɛma a wɔde si hɔ ho, na egye nnwinnade ne mfiridwumayɛfo titiriw na ama wɔatumi ayɛ adwuma.
3. Plastic Formwork: Plastic formwork yɛ kɔnkrit formwork ade foforo, a wɔde polymer nneɛma titiriw na ɛyɛ. Ɛwɔ su ahorow a ɛne sɛ emu duru yɛ hare, ɛrentumi nsɛe, ɛnyɛ den sɛ wɔbɛhohoro, na wobetumi asan de adi dwuma mpɛn pii. Plastic formwork fata ma kɔnkrit adan a ne nsusuwii ne ne kɛse gu ahorow, titiriw ma nnwuma a ɛhwehwɛ sɛ wɔde si hɔ ntɛmntɛm na wobubu gu. Bio nso, sɛnea plastic a wɔde yɛ nneɛma no yɛ torotoro no ma kɔnkrit ne ntama a wɔde yɛ nneɛma no ntam a ɛbata ho no so tew, na ɛma wotumi de nsusuwso no tu mpɔn. Nanso, plastic formwork no ahoɔden sua koraa na ɛnyɛ nea ɛfata ma kɔnkrit adan a ɛsoa nnesoa a emu yɛ duru.
4. Aluminium Alloy Nneɛma a Wɔde Yɛ Nneɛma
Aluminium alloy formwork ka mfaso a ɛwɔ dade ne nnua formwork so bom, na ɛwɔ mu duru a emu yɛ hare, ahoɔden a ɛkorɔn, na ɛko tia nsɛe. Ɛfata ma kɔnkrit adansiɛ adwuma a ne kɛseɛ nyinaa yɛ, titire no adan a ɛkorɔn-dan ne abɔntenban a ɛhia sɛ wɔde di dwuma berɛ tenten-. Aluminium alloy formwork betumi asan de adi dwuma mpɛn pii na ɛnyɛ den na ɛyɛ ntɛm sɛ wɔde besisi hɔ na wɔabubu. Afei nso, aluminum aduru a wɔde ayɛ formwork no ani a ɛyɛ tratraa a ɛkorɔn no hwɛ hu sɛ kɔnkrit nhyehyɛe no yɛ fɛ. Nanso, ɛka a wɔbɔ wɔ aluminium alloy formwork ho no yɛ kɛse koraa, na ɛhwehwɛ sɛ wosusuw adwuma no sikasɛm nhyehyɛe ne mfaso a ɛbɛba bere tenten-bere mu no ho yiye.
5. Modular Formwork a Wɔde Yɛ Nneɛma
Modular formwork yɛ formwork nhyehyɛe a wɔde nneɛma ahorow (te sɛ nnua, dade, ne plastic) na ɛyɛ. Wobetumi asiesie no wɔ ɔkwan a ɛyɛ mmerɛw so na wɔayɛ mu nsakrae sɛnea adwuma no ahiade te, a ɛfata ma kɔnkrit adan a ɛsono ne nsusuwii ne ne kɛse. Modular formwork ma wonya mfaso te sɛ emu duru a emu nyɛ duru, ɛnyɛ den sɛ wɔde besisi hɔ, na ɛho ka sua, na wobetumi apaapae nkakrankakra na wɔasan de adi dwuma bere a adwuma no rekɔ so no. Nanso, nneɛma a wɔpaw ne ɔkwan a wɔfa so boaboa ano no betumi aka sɛnea modular formwork no kyɛ ne sɛnea egyina pintinn no.
