Introduction:
PVC plastic formwork is a new kind of construction material which can replace plywood,steel formwork and other building material. It’s widely used in concrete construction made by recycled PVC powder or particles. Added with special additives and extruded at high temperature and then extrude the high density and high hardness template
Features:
1. Smooth and smooth. After demoulding, the surface and finish of concrete structure exceed the technical requirements of the existing clear water formwork. It does not need twice plastering and saves labor and material.
2. Easy to wear. Light weight, strong process adaptability, can saw, planer, drill, nail, can be arbitrarily composed of any geometric shape, to meet the needs of various shapes of building formwork.
3. Simple demoulding. Concrete does not touch the surface of the slab, does not need demoulding agent, easy demoulding, easy ash cleaning.
4. Stable and weather-resistant. It has high mechanical strength. It does not shrink, swell, crack, deform, size stability, alkali resistance, fire retardant and waterproof under the temperature range of - 20 ~60 ~C. It can resist rodents and insects.
5. Favorable for maintenance. The formwork does not absorb water and does not need special maintenance or storage.
6. Strong variability. Types, shapes and specifications can be customized according to the requirements of construction projects.
7. Reducing costs. There are many turnovers, no less than 30 planar dies, no less than 40 column and beam dies, and the cost is low.
8. Energy saving and environmental protection. Side scrap and waste template can be recycled and recycled, zero waste discharge.
Property:
1. Non-hygroscopic, anti-corrosion, acid and alkali resistant
2.High strength, impact resistance, Wear Resistance,long using life.
3. can be planed, nailed, sawed, can be used with wood formwork together.
4.No cracking fallen from 10m height.
5. No deformation under high-temperature irradiation.No cracking nailed in winter.
6. Economic, cost saving, environmental protection.
Advatages:
1. Replace of the plywood and metal formwork. Friendly to environment and energy saving.
2. Can be recycled for more than 30 times. Very economic and cost saving.
3. Easy to Install and move and deliver and save labor.
4. Subject to any temperature and humid regions.
5. Easy to take off from the concrete. Easy to relase mold.
6. Fire resistant, safe use
7. Light blue color and it is lovely in the working site.
8. Light texture, transportation and operation is easy.
9. Can be like wood as drilling, saw, nail, planer, etc.
Plastic Construction Formwork can be used in Construction Engineering, Bridge Tunnel Engineering, Water Conservancy and Hydropower Engineering, Mine Dykes and Underground Engineering, Pipeline Turnover, etc.
High-rise Building and Construction Engineering
The building formwork is a kind of temporary structure, which is made according to the design requirements, so that the concrete structure and components are shaped according to the prescribed position and geometrical dimensions, maintain their correct positions, and bear the weight of the building formwork and the loads acting on it. The purpose of carrying out the formwork project is to ensure the quality of concrete works and construction safety, speed up construction progress and reduce project cost.
Artificial:
Roof plastic formwork support: the secondary corrugation spacing is determined according to the thickness of the slab. Under general construction conditions, the secondary corrugation spacing (center spacing) of slabs less than 150 thickness is 350-400 mm, and the secondary corrugation spacing (center spacing) of 150-250 thickness slabs is 300 mm. Compared with normal bamboo plywood formwork, the spacing of secondary corrugates is increased by 50 mm, and the flatness deviation of concrete surface is smaller, which really achieves the effect of fair-faced concrete.
Shear wall plastic formwork support: take the wall height of 2800, wall thickness of 300 as an example, adopt 12mm formwork, vertical secondary rib spacing (center spacing) is 250mm; adopt 15mm formwork, vertical secondary rib spacing (center spacing) is 300mm. Compared with the normal bamboo plywood formwork, the spacing of secondary corrugates and the flatness deviation of concrete surface are basically the same, but the surface of concrete is smooth, which achieves the effect of fair-faced concrete and has better visual quality.
Plastic formwork with the same thickness has smaller deformation and larger stiffness under a certain unit and load. The surface smoothness of concrete after casting and removing formwork is better than that of bamboo plywood formwork. Under larger loads, such as shear wall formwork, the bearing capacity of formwork is larger. It is necessary to reduce the spacing of secondary corrugates or increase the thickness of plastic formwork, that is, to meet the construction technology of formwork when the lateral pressure of concrete is larger.
The assembly accuracy requirements are as follows:
1. The seam between the two templates is less than 1.
2. The difference between adjacent templates is less than 1.
3. Template flatness < 2;
4. The deviation of template plane dimension is +3.
Packing and Shipping:
1. PE film protect then packaged in carton
2. Standard export package in pallet for shipping
3. Packaged according to your requirement
