Characteristics
1.The wood batten or steel frame formwork is plastic formwork covered with wood or hollow steel.All the formwork use the same thick.
2.The frame is highly strengthened,and the wall formwork can bear lateral pressure 50KN/M2 while the column formwork can bear 70KN/m2.
3.As a standardized system,it is flexible to assemble,wood batten can be filled to satisfy the need of non-standard size.
4.The adjustable steel clamp is convenient to use
Application
Shicheng plastic hollow construction formwork be widely used in the major engineering
1.Large span\big loading\large spece of multi-layer and high-rise building
Such as commuity,shopping mall,office building,library,exhibition center,station and so on.
2.Multistory factories
3.Warehouse
4.Underground parking
5.Civil air defense projects
Precautions
1.Plastic sheets should be firmly placed on the concrete surface and all edges and corners must be kept well covered. This is done so that wind does not blow away the sheets at the edges and corners and dry out the concrete in these areas.
2.Lap joint should be minimum 300 mm between the sheets.
3.The sheets should be in close contact with the concrete surface as it causes rapid drying of the moisture from the concrete top surface.
4.The vertical surface must be firmly fixed with tapes or strings
5.Plastic sheets should be placed and fixed within half an hour of removal of formwork from vertical surfaces. On slabs, the sheets should be placed when the concrete has hardened enough to prevent surface damage.
6.Never spread wrinkling plastic sheets on the horizontal surfaces, it may cause discolouration in patches.
7.The polyethylene film should be of at least 0.10 mm i.e. 100 microns thick and preferably be transparent or white opaque in colour.
8.After placing the sheet firmly on the concrete surface, water should be allowed to flow between the concrete and the sheet.
9.After layer of soaked hessian cloth or burlaps are placed on the concrete surface they are covered with plastic sheets which help in retaining moisture for a very long time as evaporation is virtually prevented as condensation of water vapour take place on the internal site where drying shrinkage cracks and crazing are repeatedly observed.
Nowadays, water is scarce. Plastic sheets for concrete curing is the efficient method than other concrete curing methods as it saves the plenty amount of precious water.
