1. Product Overview
Wedge Anchor is an anchor bolt product that is fastened through the principle of mechanical expansion. It is mainly used for fixing heavy-load facilities of substrates such as concrete and natural stone. Its design features a trapezoidal slope structure, which is tightly fitted to the substrate through torque-driven expansion clamp ring to form a stable anchor. The product has the advantages of simple installation, strong bearing capacity and wide adaptability, and is widely used in construction, transportation, industrial equipment and other fields.
2. The core advantages
（1）convenient installation
- · Low requirements for drilling depth and cleanliness, no need for complex pretreatment, and high construction efficiency.
- · Long thread, easy to screw in operation, especially suitable for high-altitude work or narrow space scenes.
（2）High bearing capacity
- · Calibrated tensile value is based on C26~ C30 (260~ 300kgs/cm ²) concrete strength test, and the safe load does not exceed 25% of the calibrated value.
- · When the embedding depth increases, the tensile force increases synchronously, and the reliable expansion of the expansion clamp ring ensures the anti-pull and anti-shear properties.
（3）Various materials
- · Stainless steel material: strong corrosion resistance, suitable for humid, coastal or chemical environments.
- · Carbon steel material: high economy, the surface can be galvanized or dacromet treatment, to meet the needs of conventional engineering.
（4）Environmental protection characteristics
- · No dependence on chemical agents, to avoid the problem of performance attenuation of anchoring glue in high temperature and high humidity environment.
3. Technical parameters
- · Applicable substrates: C20~ C60 concrete, dense natural stone.
- · Specification range: M6~ M16 (diameter), length 30~ 200mm (can be customized).
- · Load performance: tensile strength ≥ 500MPa, shear strength ≥ 300MPa (according to material and specification differences).
- · Execution standards: GB/T 22795, ISO 10414 (carbon steel); GB/T 1220, AISI 304/316 (stainless steel).
4. Application field
- · Construction engineering: curtain wall installation, steel structure fixing, railing bracket, cable tray, etc.
- · Transportation facilities: vehicle maintenance in the body and chassis parts fixed, elevator guide rail installation.
- · Industrial equipment: heavy machinery base, pipe support, factory truss, etc.
- · Special scenarios: high temperature, high humidity environment or areas where chemical anchor bolts are not suitable.
5. Installation Guide
- · Drilling: Select the drill bit (diameter greater than 2mm of the anchor bolt) according to the specifications, and the depth is slightly longer than the effective embedding length of the anchor bolt.
- · Implant Anchor Bolt: Insert the Wedge Anchor into the hole to ensure that the expansion clamp ring fully enters the hole.
- · Fastening Operation: Use a wrench to tighten the nut until the clamp ring fully expands and fits the hole wall to avoid deformation caused by excessive torque.
- · Check Confirmation: Test the tightening force after installation to ensure that there is no loosening or displacement.
6. Selection Suggestions
- · Environmental Factors: Humid or corrosive environments give priority to stainless steel materials.
- · Load Requirements: Heavy load scenarios need to match the corresponding specifications and ensure that the embedding depth is ≥ 60mm.
- · Special needs: can be customized American standard, German standard specifications, or supporting flat pads, square clips and other accessories.
7. Brand and quality assurance
Represented by manufacturers in Yongnian, Hebei (such as Handan Tonghe Fastener Manufacturing Co., Ltd.), using automated cold pier process, Taiwan equipment and whole process quality inspection, the products have passed ISO certification, and support to map customization. Some companies provide free samples and technical support to ensure engineering adaptability.
Conclusion
Wedge Anchor has become an ideal choice for modern engineering anchorage due to the reliability and flexibility of mechanical expansion technology. Its efficient installation and stability not only reduce construction costs, but also ensure structural safety. It is an important basic component in the construction, transportation and industrial fields.
