了解混凝土锚栓紧固件的一切——类型、载荷能力、安装方法，以及如何为非洲和中东建设项目选择合适的锚栓。
混凝土锚栓类型
| Anchor Type | Load Rating | Best For | Installation |
|---|---|---|---|
| Wedge Anchor | Heavy Duty | Structural steel, heavy machinery | Through-hole, nut tightened |
| Sleeve Anchor | Medium Duty | Shelving, handrails, brackets | Through-hole, nut tightened |
| Drop-in Anchor | Heavy Duty | Flush-mount, threaded rod | Pre-drill, set with tool |
| Concrete Screw | Light-Medium | Frames, fixtures, electrical | Pre-drill, screw directly |
载荷能力与间距要求
| Anchor Diameter (mm) | Min Embedment (mm) | Min Edge Distance (mm) | Typical Tension Load (kN) |
|---|---|---|---|
| 8 | 40 | 80 | 5-8 |
| 10 | 50 | 100 | 8-14 |
| 12 | 60 | 120 | 14-22 |
| 16 | 80 | 160 | 22-35 |
| 20 | 100 | 200 | 35-55 |
安装最佳实践
可以在湿混凝土中安装锚栓吗？
不可以。机械锚栓必须在完全养护的混凝土中安装（至少28天）。湿混凝土或未充分养护的混凝土抗压强度不足，无法提供可靠的锚栓性能。
拧紧螺母时锚栓旋转怎么办？
通常意味着孔径过大或锚栓未正确膨胀。取出锚栓，必要时用正确尺寸钻头重新钻孔后重新安装。切勿过度拧紧，以免损坏膨胀机构。
