Cylindrical plywood templates are a crucial tool in the construction industry, especially for forming concrete pillars. However, one significant issue that contractors face is leakage during the concrete pouring process. In this blog post, we will explore effective methods to prevent leakage when working with wooden circular molds, ensuring a successful and safe construction project.

Step-by-Step Guide to Prevent Leakage in Circular Templates

1. Customized Circular Template Processing

To achieve optimal results, it is essential to customize the circular templates according to the design specifications outlined in the blueprints. The integration of grooves in the plywood allows for seamless joining of the templates. When securely fastened together, these templates effectively prevent leakage. One of the advantages of using cylindrical plywood is its ability to be cut into any required shape, offering greater flexibility for on-site adjustments.

2. Measurement and Marking

Accurate measurement and marking are paramount in ensuring that the pillars are erected correctly. According to the architectural design, mark the center of the column on the structural framework. Additionally, outline the column edges on the concrete slab surface. This step is instrumental in maintaining precise control over both the horizontal location and vertical alignment of the pillar.

3. Installation of Column Templates

Proper installation of the templates is critical in preventing leakage. The templates should be placed in a staggered manner for better support. Initially, use wire to secure the templates, followed by reinforcing with steel bars. Maintain a spacing of 20-30 centimeters between the reinforcing bars. After securely fastening the templates, ensure that the bottom circular face is positioned 0.5 to 1 cm above the ground before filling the seams with concrete.

4. Steel Band Installation

When installing the steel bands, it is essential to use a steel measuring tape to verify that the templates are consistent in height all around. Hammer in 3-4 small nails around the same height on the circular plywood template. As you place the steel bands, insert them into the nails to keep the bands level. Additionally, ensure that each screw is tightened uniformly to maintain equal tension across the steel bands, enhancing both the stability and safety of the construction.

By following these essential steps, contractors can effectively prevent leakage when using cylindrical plywood templates in construction. A well-prepared and properly executed template installation not only improves the quality of the concrete structure but also ensures the safety and integrity of the entire project. Remember that attention to detail in the installation process will greatly contribute to the overall success of your construction endeavors. Implement these practices and enjoy leak-free results with your circular templates!
