recycled high quality concrete formwork panels

Product Details

Yaohang hollow plastic building formworks breaks through the drawbacks of the traditional template, and perfectly combines the advantages of the traditional building formwork, completely replacing the traditional formwork, saving more cost for the construction project, and is more conducive to protecting the environment and saving resources. The status quo of hollow plastic building formworks, traditional building formworks mainly use bamboo formwork, wood formwork, steel formwork or aluminum alloy formwork. These templates have their own advantages, but with the development of social science and technology, the construction industry has proposed a new development. Demand, traditional formworks can not meet the growing demand.

The hollow plastic building formwork is made of high-quality raw materials and has stable chemical and physical properties. It can be made of anti-corrosion, moisture-proof, acid-proof, alkali-resistant, insect-proof, etc., and it is not delaminated, cracked, and not easily deformed. The water is deformed, but it can change its shape according to various accessories. It can meet the needs of a wider range of buildings. The status quo of hollow plastic building formworks, hollow plastic building formworks are now widely used in the field of bridges and tunnels, because it has good water resistance, it is not easy to deteriorate when it is soaked in water, it is not affected, and its shape can also become curved surface according to demand, which is more conducive to engineering construction and protect construction safety.

Plastic concrete formwork usage and precautions:

1. The method of use is the same as the wooden template. The direction of the vertical ribs of the hollow plastic formwork is crossed with the direction of the wood.

2. It is not necessary to apply a release agent before use.

3. When the cast-in-place plate is used, the distance between the keels is 20-25cm, and the distance between the keels of the plate wall is 10-20cm.

4. The joint between the board and the board needs to be sealed with tape.

5,.The length of the nail should not be too long, generally 30-35mm, about right and left.

6, Nail strength should be moderate.

7. When removing the mold, it is necessary to carry out the small block at one end, and remove the template while removing the support to prevent large areas from falling, and do not let the corners fall perpendicularly to the ground.

8. The formwork can be mixed with wood plywood, bamboo glue board and other material plates.

Cause for failures of concrete formwork:

1.Inadequate bracing

2.Vibration

3.Unstable soil

4.Inadequate control of concrete placement

5.Improper stripping and shore removal

6. Concreting practice control

7.Striping of forms strength of concrete
