Wooden formwork is a critical component in construction, especially in concrete pouring projects. The thickness of wooden formwork can vary based on its intended use and specific project requirements. Understanding these variations is essential for ensuring the structural integrity and efficiency of construction operations. In this article, we will discuss the common thickness dimensions of wooden formwork, as well as the materials typically used.

Common Thickness Dimensions

1. Foundation Formwork: 

 For components like side panels of foundation beams, the typical thickness is around 20 mm. The materials used include pine wood, poplar wood, and eucalyptus wood, which offer durability and strength.

2. Main Beam Bottom Formwork: 

When it comes to the bottom formwork for main beams, the thickness generally increases to 40 mm. Again, pine wood is commonly used due to its strong structural properties.

3. Column and Floor Formwork: 

In many instances, mechanized wooden formwork is utilized, with a standard thickness of 12 mm. This thinner formwork is suitable for various vertical and horizontal applications across the construction site.

National Standard Thickness Range

It's important to note that the national standards specify a thickness range for wooden formwork between 12 mm to 20 mm. This ensures that the formwork used is adequate for the intended load and pressure exerted by the concrete.

Wooden formwork produced in various specifications, commonly featuring multi-layer boards such as 7-layer, 8-layer, and 9-layer forms. These different specifications allow construction professionals to choose the appropriate formwork based on their unique project requirements.

In conclusion, understanding the various thicknesses and materials associated with wooden formwork is vital for construction professionals. From the 20 mm thickness used in foundation formwork to the 40 mm required for main beam formwork, selecting the right specifications can significantly impact the success of concrete projects. Always ensure that the wooden formwork you choose adheres to national standards and meets the specific needs of your engineering requirements.
