What are the differences in construction techniques between plastic formwork and wooden formwork?

2024-08-21

Plastic formwork and wooden formwork, as formwork tools for construction, have differences in construction techniques in the following aspects:
Installation method
Wooden formwork: usually requires the use of iron nails for fixation. When nailing, attention should be paid to the strength and position to avoid cracking the wooden board.
Plastic template: Due to the characteristics of the material, it is generally fixed with bolts, buckles and other connectors to avoid direct nail damage to the template.
Splicing processing
Wooden formwork: There may be gaps at the joints, and additional joint filling materials are required to ensure sealing and concrete forming quality.
Plastic template: The splicing is relatively tight with small gaps, but it may still require the use of sealant or other treatments to prevent leakage.
Demolding process
Wooden formwork: Before demolding, it is necessary to apply a release agent. There may be some adhesion during demolding, so careful operation is needed to avoid damaging the concrete surface and formwork.
Plastic template: Smooth surface, easy demolding, and good concrete forming effect.
Cutting and processing
Wooden template: It can be cut using tools such as electric saws and manual saws, making it relatively easy to operate.
Plastic template: requires the use of an electric cutting machine, and the debris generated during cutting is different from that of wooden templates.
support system 
Wooden formwork: Due to its light weight, the requirements for the support system are relatively low.
Plastic template: It is lightweight, but in order to ensure stability, the design and construction of the support system still need to comply with regulations.
Turnover times
Wooden formwork: The turnover is limited, usually 5-8 times, and it is prone to deformation after multiple uses, which affects the construction quality.
Plastic template: With a turnover of over 50 times, it can be reused in multiple projects.
Storage and protection
Wooden formwork: Attention should be paid to moisture, fire, and insect infestation prevention, and the storage environment requirements are relatively high.
Plastic template: Good water resistance, anti-corrosion, V2 fire rating, flammable but non combustible, requires better fire resistance, can be customized with alloy plate.
Cleaning and maintenance
Wooden formwork: The surface is prone to adhering concrete residues, making cleaning more laborious.
Plastic template: Smooth surface, relatively easy to clean.
