Formwork !

Assalammualaikum

Harap semuanya sihat...

Dah lama saya tak 'tulis' sesuatu dalam blog ni...

Sekarang di tapak ..banyak kerja 'Formwork' ...

Apa tu 'formwork' - senang cerita kerja-kerja melibatkan membuat acuan tempat konkrit...itu dalam bahasa mudahlah..nak tau cobalah serch lebih lanjut dalam goggle ye.

Bila saya search ada satu web bagus khusus berkenaan kerja-kerja formwork di tapak bina.Nak tau lebih lanjut layari web berikut

Bagus untuk sesiapa yang berkerja atau belajar berkenaan 'construction'.

Sebahagian info dari Wekipedia - ginilah aku belajar kat site ...

Formwork and concrete form types[edit]

Formwork comes in several types:

1. Traditional timber formwork. The formwork is built on site out of timber and plywoodor moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring reusable formwork. It is also the most flexible type of formwork, so even where other systems are in use, complicated sections may use it.
2. Engineered Formwork System. This formwork is built out of prefabricated modules with a metal frame (usually steel or aluminium) and covered on the application (concrete) side with material having the wanted surface structure (steel, aluminum, timber, etc.). The two major advantages of formwork systems, compared to traditional timber formwork, are speed of construction (modular systems pin, clip, or screw together quickly) and lower life-cycle costs (barring major force, the frame is almost indestructible, while the covering if made of wood; may have to be replaced after a few - or a few dozen - uses, but if the covering is made with steel or aluminium the form can achieve up to two thousand uses depending on care and the applications).
3. Re-usable plastic formwork. These interlocking and modular systems are used to build widely variable, but relatively simple, concrete structures. The panels are lightweight and very robust. They are especially suited for low-cost, mass housing schemes.
4. Permanent Insulated Formwork. This formwork is assembled on site, usually out of insulating concrete forms (ICF). The formwork stays in place after the concrete has cured, and may provide advantages in terms of speed, strength, superior thermal andacoustic insulation, space to run utilities within the EPS layer, and integrated furring strip for cladding finishes.
5. Stay-In-Place structural formwork systems. This formwork is assembled on site, usually out of prefabricated fiber-reinforced plastic forms. These are in the shape of hollow tubes, and are usually used for columns and piers. The formwork stays in place after the concrete has cured and acts as axial and shear reinforcement, as well as serving to confine the concrete and prevent against environmental effects, such ascorrosion and freeze-thaw cycles.

Untuk kali ni cukuplah.Jumpa lagi di lain masa
