Description
Green Plastic’s PP Hollow Formwork is new kind of constrution concrete formwork. It is used high quality recycled polypropylene particles. It is suitable to realize concrete columns, pillars, walls, plinths, and foundations directly onsite. This formwork is according to the principle of structural mechanics, neatly arranged, increased four times support, stronger and more robust, on both sides of the formwork are right angle processing, increasing the bear capacity, construction is more convenient, its hollow structure makes the product expansion coefficient small and light easy to move. Now PP hollow structure formwork is becoming more and more popular.
1.Reuse average times more than 60, long service life.
2.High hardness. Can bear high press from the cement or concrete.
3.Good tenacity, within tolearence expansion, and shrinkage.
4.Light weight and easy to remove,operate and transport.
5.Waterproof, non-hygroscopic,size stable under the water.
6.The surface is smooth and clean, easy demould, no need mold release agent.
7.Good toughness. It could be used as cambered special-shaped formwork.
8.Waste products can be recycled and reprocessed, making full use of waste materials. This property can greatly reduce the project cost compared with wooden formwork and bamboo formwork.
9.Environmental protection and energy saving, no pollution. No any poisonous or harmful gas.
10. No absorption of moisture, no deformation, no mildew; Long-term immersion stratification in the water, no bubbles, sheet size stability, especially suitable for underground and damp environment.
1.Use the hollow building formwork intersecting surface laid with 15mm thick.
2.Wood square of the distance:
(1) on the surface of the intersection (spacing: wood square distance according to the thickness of the slab concrete, in general, the thickness of less than 0.15 m floor (spacing is 200 ~ 250 mm.)
(2) the shear wall (spacing according to adjust the spacing, height and thickness of the wall to wall height of 2800 mm, 300 mm thick wall, for example, using the formwork (15 mm thickness spacing is 100 ~ 150 mm, if the shear wall, pillar width more than 1 meter, must add the fixed frame.
3.Die shear wall and column puzzle when leaving no gaps, internal Angle (the bottom of the wall) parts must have wood square, beam, wall, formwork connection.Shear wall made
4. After the mold must be assembled into the whole hoisting, then lay flat, reduce labor intensity, forming effect is good.
5. When the nail to the formwork from the formwork edge distance 15 ~ 30 mm, strength wants moderate, nail nails is 40 ~ 50 mm in length, shoulds not be too long or too short.
6.Beam bottom of a piece of wood square must set aside 15 mm seam allowance, wallboard made on wood square seam allowance, it does not leak slurry and wallboard material saving.
