Product Description

Discover the revolutionary Concrete Self-Tapping Anchor Bolt, a post-anchoring marvel that expertly forms an anchoring effect directly in concrete through its powerful hard threads. Let's embark on a comprehensive analysis from various perspectives:

1, Core Features

1. Self Attack Anchoring Mechanism

Harnessing the power of high-hardness threads, typically of grade 10.9 or higher carbon steel, this unique bolt executes a direct incision into the concrete wall, creating a robust threaded interlocking structure. No pre-drilling or chemical agents required! Its exceptional anchoring strength stands the test of destructive tensile evaluations, often resulting in the concrete cone's failure, rather than the sturdy anchor bolt body itself.

2. Ingenious Reversible Installation Design

Facilitates easy disassembly by adjusting the rotation direction, making it an ideal choice for temporary fixtures such as scaffolding or formwork support. This adaptability significantly reduces costs associated with engineering renovations.

2, Technical Parameters and Adaptability

1. Specification Matching Principle

Ensure perfect alignment between the anchor bolt diameter and the opening diameter (e.g., M8 anchor bolt matches an 8mm drilling hole). Various length models (e.g., 6 × 35, 6 × 55) harmonize with different substrate thicknesses, ensuring the anchoring depth meets all load-bearing requirements.

2. Material Performance Grading

• Basic Version: Crafted from Grade 8.8 or higher carbon steel, tailored for standard environments.

• Anti-Corrosion Enhanced Version: Features a robust combination of 410 stainless steel with surface anti-corrosion treatment, perfect for enduring extreme conditions like marine climates and chemical exposure.

• High Strength Version: Utilizing 12.9 grade carbon steel, this variant is ideal for securing heavy equipment and seismic fortification zones.

3, Application Scenarios

1. Building Structure Reinforcement

Perfect for swiftly anchoring seismic supports and suspension systems in concrete beams, slabs, columns, and more, without compromising substrate integrity.

2. Equipment Installation

Designed for securing curtain wall keels and MEP pipeline supports, its compact installation margin adeptly navigates complex spatial layouts.

3. Temporary Works

Achieve quick, detachable anchoring for scaffolding and stage structures, enhancing efficiency at event venues and exhibition setups.

4, Technical Advantages

1. Unmatched Construction Efficiency

Compared to traditional expansion anchor bolts, installation time per piece is slashed by over 60%, with no waiting for adhesive curing required.

2. Superior Bearing Capacity

In C30 concrete, a single anchor bolt exhibits impressive tensile bearing capacities of 8-15kN and shear capacities of 5-10kN (specifications dependent).

3. Exceptional Environmental Adaptability

With advanced material upgrades, it withstands temperature ranges from -20 ºC to 80 ºC, boasting IP68 dust and water resistance.

5, Selection and Construction Points

1. Thorough Substrate Evaluation

Test for concrete strengths (recommended C25 or above), crack widths (≤ 0.3mm), and steel densities to prevent conflicts between anchor bolts and steel reinforcements.

2. Precision Tool Matching

Opt for an electric wrench with torque control, ensuring installation torque remains within ± 15% of the nominal value for precision.

3. Rigorous Quality Control

After installation, conduct a sampling pull-out test to ensure the bearing capacity meets the rigorous standard of 1.5 times the design value.
