In modern infrastructure projects, such as highways, airports, and industrial pavements, managing thermal expansion and contraction in concrete slabs is a critical engineering challenge. SupAnchor's GFRP (Glass Fiber Reinforced Polymer) Dowel Bar provides an innovative solution, designed to ensure efficient load transfer and long-term structural integrity. This product line, manufactured from premium raw materials, addresses the need for reliable mechanical links in construction joints, offering a significant upgrade over traditional materials.
The SupFRP® GFRP Dowel Bar functions as a "load transfer" device, connecting adjacent concrete slabs while allowing horizontal movements to accommodate temperature changes. This prevents cracks and ensures stability, making it ideal for projects with demanding environmental conditions. Key technical features include a service life exceeding 100 years, no-rust properties, high strength, and superior load transfer efficiency. The dowel bar is non-conductive and non-magnetic, suiting it for applications in areas with electromagnetic sensitivities, such as near medical facilities or communication hubs.
To illustrate the product's versatility, here are the technical parameters for various sizes, highlighting how they meet specific engineering needs:
| Model | Outside Diameter (mm) | Transverse Shear Load (kN) | Nominal Cross-sectional Area (sq. m) | Coefficient of Thermal Expansion (x10-6/°C) | Weight (kg/m) |
|---|---|---|---|---|---|
| DB16 | 16 | 35 | 200 | 9-11 | 0.43 |
| DB20 | 20 | 55 | 310 | 9-11 | 0.67 |
| DB25 | 25 | 85 | 490 | 9-11 | 1.05 |
| DB32 | 32 | 130 | 800 | 9-11 | 1.71 |
| DB38 | 38 | 180 | 1130 | 9-11 | 2.41 |
| DB45 | 45 | 255 | 1590 | 9-11 | 3.37 |
These specifications enable engineers to select the appropriate dowel bar based on load requirements and site conditions. For instance, higher shear load capacities in models like DB45 make them suitable for heavy-duty applications, while the consistent thermal expansion coefficient across sizes ensures predictable performance in variable climates. The customization options further enhance adaptability, allowing for tailored solutions in complex projects.
