Crafts of Plastic Templates
Roof plastic formwork support: the distance between the sub-corrugations is determined according to the thickness of the plate. Under normal construction conditions, the distance between the sub-corrugations (center distance) for floors less than 150 thick is 350 to 400 mm; Compared with the normal use of bamboo plywood formwork, the spacing of the secondary corrugations is increased by 50mm, and the flatness deviation of the concrete surface is smaller, which truly achieves the effect of fair-faced concrete.
Shear wall plastic formwork support: Take the wall height of 2800 and the wall thickness of 300 as an example, using 12mm formwork, the vertical secondary rib spacing (center distance) is 250mm; using 15mm formwork, the vertical secondary corrugation spacing (center distance) is 300mm. Compared with the normal use of bamboo plywood formwork, the spacing of the second corrugations and the flatness deviation of the concrete surface is basically the same, but the concrete surface is smooth and clean, achieving the effect of fair-faced concrete, and the appearance quality is better.
The plastic formwork of the same thickness, within a certain unit and under a certain load, has less deformation and greater rigidity, and the surface flatness after concrete pouring and formwork removal is better than that of bamboo plywood formwork. Under the action of a large load, such as shear wall formwork, the formwork bearing capacity is large, and it is necessary to reduce the spacing of the secondary corrugations or increase the thickness of the plastic formwork, which can meet the construction technical requirements of the formwork when the concrete lateral pressure is large.
Plastic formwork has become a new favorite in the construction industry because of its environmental protection and energy-saving, economical and affordable through recycling, and waterproof and corrosion resistance. This product will gradually replace the wood formwork in the building formwork, thus saving a lot of wood resources for the country, and playing a huge role in protecting the environment, optimizing the environment, and reducing low carbon emissions. Plastic formwork effectively utilizes waste resources. It not only meets the requirements of national energy conservation and environmental protection but also adapts to the development direction of national industrial policies. It is a new revolution in formwork materials for construction projects.
After the plastic template is used, it can be crushed into powder and then processed into a plastic template as raw material, and then reused. In this way, it can be used repeatedly and in response to the national call for environmental protection.
