The PP hollow formwork produced by Greensaver is a new type of construction concrete formwork. It is made of high quality recycled polypropylene granules.It is suitable for realizing concrete columns, pillars, walls, plinths, and foundations directly on site. This kind of formwork is neatly arranged according to the principle of structural mechanics, which increases the quadruple support force and is more solid, with right angle treatment on both sides of the formwork, which increases the bearing capacity and makes the construction more convenient and its hollow structure makes the product with small expansion coefficient and light weight for easy movement. Now PP hollow structure construction formwork is more and more popular.
Specification for the use of plastic formwork
1.Scope of use:
Plastic formwork is very suitable for horizontal formwork of high-rise buildings, shear walls, vertical wall panels, dam, tunnel and bridge formwork, etc.
2.Sawing formwork:
The plastic formwork is suitable for any saw blade, hand saw, chainsaw, etc. Can be cut into any irregular geometric shape by chainsaw without any burr.
3.Formwork laying standards:
Square timber immediately adjacent to the formwork, laid lengthwise. The board seam should be as narrow as possible, and the board should be flat between the boards. Self-adhesive tape for board seams.
（1）Top mold：First on the scaffold horizontal laying wood square spacing of about 1.2m, and then longitudinal laying wood square, the spacing does not exceed 200-300mm, the thickness of the poured more than 200mm, the spacing should be adjusted appropriately small.（2）Wall mold：Square timber shall be laid longitudinally behind the formwork with a spacing of 150-200mm. Then lay two square timbers horizontally for connection, reserve the position of through wall screws, erect diagonal braces, and horizontally connect the steel ridge to form a large wall formwork, which can be directly hoisted or replaced with a single formwork.
（3）Beam and column mold：Cut the formwork according to the size, leave the top through the wall bolt position, the column mold available scaffolding four side locking, set up a good diagonal brace.
Strong points for our plastic formwork
1.Save labor and time
The surface of our plastic formwork is flat and smooth, the formwork splicing is tight and flat, and the surface degree and finish of the concrete structure after demoulding exceeds the technical requirements of the existing clear water formwork, which does not require secondary plastering and saves labor and materials.
2.Lightweight and easy to install
Plastic construction formwork is not only light and easy to install, but also has strong adaptability, can be nailed, sawed, shaved, drilled, no cracking, no deformation, no maintenance and care. With accessories can be composed of any geometric shape, to meet the needs of various shapes of building construction support.
3.Easy to demould
Concrete non-stick mold surface, no need for release agent, easy to demould and easy to clean ash.
4.High temperature resistance
High mechanical strength, no shrinkage, no wet swelling, no cracking, no deformation, dimensional stability, alkali-resistant and anti-corrosion, flame retardant and waterproof, rodent and insect resistant under -20℃ to +60℃ temperature conditions.
5.High strength and rigidity
In the two indexes of impact strength and bending, it has far surpassed plywood.
6.Low cost
Plastic formwork can be reused about 30 times, and the thermal expansion and contraction fraction is low, comparable to that of wooden template.
7. Environmental protection and energy saving
Waste formwork and trimmings can all be recycled, no waste pollution emission.
8.cost performance
15mm plastic formwork 150 yuan / pc (recycling 35 yuan / pc, the actual 115 yuan / pc) available 30 times, each time the cost needs 3.83 yuan.
14mm wooden formwork 60 yuan / pc (non-recyclable), can be used 6-8 times, each time the cost of 8.57 yuan.
