Usage Method:
1. This product does not need release agent.
2. The spacing of the roof timber brace is adjusted by the thickness of the concrete, under normal construction conditions, for 150mm thickness floor, the center distance of the adjacent wood brace should be 300mm; The shear wall with a thickness of 300mm and a height of 2800mm, the center distance of the adjacent wood brace should be less than 250mm, and the bottom of the wall should have wood brace; Depending on the thickness and height of the wall to increase or decrease wood brace spacing; Column width exceed 1 meter must be fixed.
3. The inside corners should have wood brace, for easy connection between the beam and wall.
4. This product can be mixed with plywood of the same thickness.
5. Please use the alloy saw blades with more than 100 mesh to cut the formwork.
6. The use of this product should be disassembled according to the specific location, and avoid unnecessary waste of cutting.
7. Strengthen the worker's safety training before use, improve the awareness of fire prevention, and strictly prohibit smoking at the construction area. It is strictly prohibited to use open fire. Fire blankets should be placed near and below the solder joints before welders operation.
Perforated formwork can be made from a variety of materials such as metal, plastic or cardboard. It is commonly used in construction for walls, columns and other concrete structures.
One of the advantages of using perforated formwork is that it can be easily removed from the concrete once it has cured. This can save time and labor costs on the construction project.
Another advantage of perforated formwork is that it can allow for better ventilation during the curing process which can improve the quality and strength of the concrete.
Overall, perforated formwork can be a useful tool on construction projects where the quality and strength of the concrete is important.
