使用 FRP 钢筋轻松实现隧道突破
Retrofit Structural Solutions Based on CFRP
ASTEC Carbon Solutions is a range of three products based on the same innovative composite material: Carbon Fiber Reinforced Polymer. ASTEC CFRP offers amazing properties: four times the tensile performance of steel for only one-quarter of the weight.
In the past 20 years, new structural applications for carbon fiber-based elements have emerged:
- External Bonding Reinforcement (EBR): A carbon laminate is applied on the surface to increase the flexural and shear strength of the member.
- NSM (Near Surface Mount) Applications: A carbon rod or tape is inserted in a cut groove with cement grouting or epoxy adhesive. NSM offers a gain of 4.8 times the flexural strength compared to the EBR technique.
- External Post-Tensioning Applications: A carbon rod is installed below a concrete member thanks to a state-of-the-art splicing system.
产品特点
- 层压板：宽度为 50 或 100 毫米，厚度为 1.4 毫米，极限拉伸载荷高达 336 kN。
- Tape: 16mm width and available in two thicknesses for an ultimate tensile load of 140 kN.
- 杆：3 种直径，极限拉伸负载能力高达 218 kN。我们的杆解决方案采用创新的连接器，可作为 PT 应用进行安装。
- 根据 ACI440.2R-08、ACI440.74、ACI-440.7R 和 FIB 任务组 9.3 设计。根据 ACI 440-3R-12 进行测试。

好处
- 安装速度快。
- 成本有效。
- 耐用：无需维护，无需后期检查。
- 由于尺寸紧凑，并且 CFRP 隐藏在切割槽中，因此视觉影响有限。
- 可在各种天气条件下安装。
- 也适合木结构。
