Plastic formwork is a composite material made by 200¡æ high temperature extrusion based on the digestion and absorption of advanced European equipment manufacturing technology and semi-high processing experience, with advanced products and process technology. Plastic formwork is an energy-saving and green environmentally friendly product, and is a new generation product after wooden formwork, combined steel formwork, bamboo-wood glued formwork, and all-steel large formwork.
Plastic formwork can completely replace traditional steel formwork, wooden formwork, and square timber, which is energy-saving and environmentally friendly, and has low amortization cost.
The turnover of plastic formwork can reach more than 30 times, and it can also be recycled. It has a wide temperature adaptation range, strong specification adaptability, can be sawed and drilled, and is easy to use. The flatness and finish of the formwork surface exceed the technical requirements of the existing plain concrete formwork, and it has the functions of flame retardancy, corrosion resistance, water resistance, and chemical corrosion resistance, and has good mechanical properties and electrical insulation properties. It can meet the requirements of various rectangular, cube, L-shaped, and U-shaped building formwork.
China's plastic formwork has experienced more than 30 years of development. Since 1982, Chinese companies have developed glass fiber reinforced plastic formwork, sand plastic and wood plastic board formwork, strong plastic PP formwork, bamboo reinforced wood plastic formwork, plastic formwork, PVC foam plastic formwork and other plastic formwork products.
PVC plastic formwork has high strength, wide temperature adaptability, drop resistance, and is not brittle. The static bending strength of the formwork reaches 22MPa, and it can be normally constructed at -20 degrees to +60 degrees. It is a sign of the arrival of another revolution in China's formwork industry.
The product range is rich: plastic steel formwork, plastic steel formwork, plastic steel square wood, plastic steel Yin and Yang corners, plastic steel cylindrical formwork, plastic steel bridge formwork and other special-shaped formwork.
According to the material, it can be divided into: polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), high-density polyethylene (HDPE), etc. According to the appearance, it can be divided into: solid board, hollow board, snap-on rib board, modular assembly board, plastic square wood, plastic yin and yang corners.
Top plate plastic formwork support: The spacing of the secondary ribs is determined according to the thickness of the board. Under normal construction conditions, the spacing of the secondary ribs (center distance) of the floor slab less than 150 thick is 350-400mm; the spacing of the secondary ribs (center distance) of the floor slab 150-250 thick is 300 mm. Compared with the normal bamboo plywood formwork, the spacing of the secondary ribs is increased by 50mm, and the flatness deviation of the concrete surface is smaller, which truly achieves the effect of fair-faced concrete.
Support of plastic formwork for shear wall: Taking the wall height of 2800 and the wall thickness of 300 as an example, a 12mm formwork is used, and the vertical secondary rib spacing (center distance) is 250mm; a 15mm formwork is used, and the vertical secondary rib spacing (center distance) is 300mm. Compared with the normal use of bamboo plywood formwork, the spacing of the secondary ribs and the flatness deviation of the concrete surface are basically the same, but the concrete surface is smooth, achieving the effect of clear concrete, and the visual quality is better.
For plastic formwork of the same thickness, within a certain unit and under a certain load, the deformation of the plastic formwork is small and the rigidity is large. The surface flatness after concrete pouring and demolding is better than that of bamboo plywood formwork. Under large loads, such as shear wall formwork, the formwork bearing capacity is large, and it is necessary to reduce the spacing of the secondary ribs or increase the thickness of the plastic formwork, that is, to meet the construction technical requirements of the formwork when the concrete side pressure is large.
Plastic formwork is a new favorite in the construction industry because of its environmental protection and energy saving, its recycling economy and affordability, and its waterproof and corrosion resistance. This product will gradually replace the wooden formwork in the construction formwork, thereby saving a large amount of wood resources for the country, and playing a huge role in protecting the environment, optimizing the environment, and reducing carbon emissions. The plastic formwork effectively utilizes waste resources. It not only meets the requirements of the country's energy conservation and environmental protection, but also adapts to the direction of the development of the national industrial policy. It is also a new revolution in the formwork materials of construction projects.
After use, the plastic formwork can be crushed into powder and then processed into plastic formwork as raw materials, and then reused. In this way, it can be recycled repeatedly to respond to the national call for environmental protection.
1. Smooth and smooth. The formwork is tightly spliced and smooth. After demoulding, the surface and finish of the concrete structure exceed the technical requirements of the existing clear water formwork. No secondary plastering is required, saving labor and materials.
2. Lightweight and easy to install. Lightweight, strong process adaptability, can be sawed, planed, drilled, nailed, can be freely formed into any geometric shape, to meet the needs of various shapes of building formwork.
3. Easy demoulding. Concrete does not stick to the board surface, no release agent is required, easy demoulding, easy to clean.
4. Stable and weather-resistant. High mechanical strength, no shrinkage, no swelling, no cracking, no deformation, dimensional stability, alkali resistance and corrosion resistance, flame retardant and waterproof, rat and insect repellent.
5. Conducive to maintenance. The formwork does not absorb water and does not require special maintenance or storage.
6. Strong variability. Types, shapes and specifications can be customized according to the requirements of construction projects.
7. Reduce costs. The turnover times are high, the flat formwork is not less than 30 times, the column and beam formwork is not less than 40 times, and the use cost is low.
8. Energy saving and environmental protection. All scraps and waste formwork can be recycled and reused, with zero waste discharge.
