DO you know what is Plastic building template?Plastic building template
The plastic building template is an energy-saving and environmentally friendly product. It is a new type of replacement product after the wooden template, combined steel template, bamboo-wood glued template and all-steel large template. It can completely replace the traditional steel formwork, wooden formwork, square wood, energy saving and environmental protection, and low amortization cost.
Chinese name plastic building template, foreign name Plastic Formwork, special energy saving and environmental protection, low amortization cost, classification of solid board, hollow board, turnover of more than 30 times

The turnover of plastic building templates can reach more than 30 times, and can be recycled. Large temperature adaptability range, strong adaptability to specifications, can be sawed and drilled, easy to use. The flatness and smoothness of the surface of the formwork exceed the technical requirements of the existing fair-faced concrete formwork. It has the functions of flame retardant, anticorrosion, water resistance and chemical resistance, and has good mechanical properties and electrical insulation properties. It can meet the requirements of various cuboid, cube, L-shaped and U-shaped building formwork.
Plastic building template is a composite material that is adhered to advanced products and process technology and extruded at a high temperature of 200℃ based on digesting and absorbing European advanced equipment manufacturing technology and half-high processing experience.
The new composite material hollow building template adopts imported polypropylene resin as the base material, adding toughening, strengthening, weathering resistance, anti-aging, flame retardant and other chemical additives, after chemical molecular structure reorganization, a plastic sheet product smelting and extrusion molding.
Hollow building formwork can be recycled 80-100 times, and the overall cost is more than 20% less than the wooden formwork. It is an ideal new formwork. The triangular structure of the new material hollow building template is neatly arranged according to the principle of mechanics, with heat resistance, cold resistance and small expansion coefficient. Solved the defect of warping deformation of solid template.
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 rib board, module assembly board, plastic square wood, plastic yin and yang angle
China's plastic building templates have experienced more than 30 years of development. Since 1982, China's enterprises have developed glass fiber reinforced plastic building templates, sand plastic and wood plastic board templates, strong plastic PP templates, bamboo reinforced wood plastic Plastic formwork products such as formwork, plastic formwork, and PVC foamed plastic formwork.
The produced PVC plastic construction formwork has high strength, wide temperature adaptability range, drop resistance, no brittleness, strong nail absorption force, static bending strength of formwork reaching 22MPa, and normal construction at -20 degrees-+60 degrees. It is a sign of another revolution in the template industry in my country.
1. Smooth and clean. The splicing of the formwork is tight and smooth, and the surface and finish of the concrete structure after demoulding exceed the technical requirements of the existing clear water formwork, without the need for secondary plastering, saving labor and materials.
Second, light and easy to install. Light weight, strong process adaptability, can be sawed, planed, drilled, nailed, can be formed into any geometric shape at will, to meet the needs of various forms of building support.
3. Easy demoulding. The concrete does not stick to the slab surface, no mold release agent is needed, the mold release is easy, and the dust is easy to clean.
4. Stable weather resistance. High mechanical strength, no shrinkage, no swelling, no cracking, no deformation, stable size, alkali resistance, corrosion resistance, flame retardant and waterproof, mouse and insect resistance under the temperature condition of -20℃ to +60℃.
5. Conducive to maintenance. The template does not absorb water and does not require special maintenance or storage.
6. Strong variability. The type, shape and specifications can be customized according to the requirements of construction projects.
7. Reduce costs. There are many turnovers, the plane mold is not less than 30 times, the column beam mold is not less than 40 times, and the use cost is low.
8. Energy saving and environmental protection. All the scraps and waste templates can be recycled and recycled, with zero waste discharge.
High-rise commercial buildings are mainly used for roofing, beams, walls, columns, stairs and foundation pouring, bridge tunnels, water conservancy and hydropower projects, mine dams and underground projects.
(1) Roof plastic construction formwork support: The secondary flute spacing is determined according to the plate thickness. Under general construction conditions, the secondary flute spacing (center distance) of less than 150 thick floor slabs is 350～400mm; the secondary flute spacing of 150～250 thick floor slabs (center distance ) Is 300 mm. Compared with the normal use of bamboo plywood formwork, the distance between the secondary flutes is increased by 50mm, the deviation of the flatness of the concrete surface is smaller, and the effect of clear concrete is truly achieved.
(2) Shear wall plastic construction formwork support: Take wall height 2800 and wall thickness 300 as an example, use 12mm formwork, vertical secondary rib spacing (center distance) is 250mm; use 15mm formwork, vertical secondary flute spacing (center Distance) is 300mm. Compared with the normal use of bamboo plywood formwork, the deviation of the secondary flute and the flatness of the concrete surface are basically the same, but the surface of the concrete is smooth and clean, which achieves the effect of clean concrete and has a better look and feel quality.
"Replace wood with plastic"
Plastic building templates are environmentally friendly and energy-saving, economical and economical with recycling, and become the new darling of the construction industry with waterproof and corrosion resistant. The product will gradually replace the wooden 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 building templates effectively use waste resources. He 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 also a new revolution in the construction of construction template materials.
