Flat-Ended Inverted Cone

Inverted Cone Shape: The head of the inverted - cone - shaped chemical anchor bolt is in an inverted cone shape. This design enables the anchor bolt, after installation, to form a better mechanical interlocking effect with the concrete substrate. When subjected to tensile or shear forces, the inverted - cone part can more effectively transfer the forces to the concrete, thus improving the reliability and load - bearing capacity of the anchorage.

Advantage



High Load-Bearing Capacity

The Flat-Ended Inverted Cone anchor bolt excels in handling extreme forces, thanks to its dual-action mechanism: chemical adhesion and mechanical interlock. It withstands tensile forces up to 50kN and shear forces exceeding 35kN (tested under standard concrete conditions), making it suitable for heavy-duty scenarios such as bridge construction, industrial equipment installation, and high-rise building frameworks. This strength ensures long-term stability even under constant or dynamic loads.


Superior Corrosion Resistance

Manufactured using 5.8-grade carbon steel or 304/316 stainless steel, the anchor bolt resists rust and environmental erosion. Many models undergo hot-dip galvanizing or electroplating treatments, forming a protective layer that extends service life to 15+ years in harsh conditions (e.g., coastal areas, industrial zones with chemical exposure). This resistance reduces maintenance costs and ensures reliability in outdoor or humid environments.


Seismic Performance

Designed to perform under dynamic loads, the inverted cone structure maintains a tight bond with concrete during earthquakes or vibrations. Tests show it retains 90% of its anchoring strength after 10,000 cycles of seismic simulation, outperforming conventional anchors. This makes it a top choice for seismic brackets, emergency exit systems, and infrastructure in earthquake-prone regions.


Easy Installation

The installation process is streamlined, requiring only four steps: drilling (using standard masonry drills), hole cleaning (to remove dust/debris), glue injection (compatible with TEDUN’s epoxy adhesives), and screwing in the anchor. No specialized equipment is needed, reducing on-site labor time by 30% compared to mechanical expansion anchors. This efficiency accelerates project timelines without compromising quality.


Application



  • Rail Transit: In projects like subway and high - speed rail tunnels, it is applied to anchor key components such as catenary supports and pantograph arms, guaranteeing the stability of the catenary during the operation of high - speed trains. It can also be used for anchoring in - tunnel joint - sealing cover plates and emergency escape platforms.


  • Building Structures: In structures such as high - rise buildings and bridges, it is used to fix steel - structure components like steel beams and columns, ensuring the overall stability of the steel structure. It can also be applied to the reinforcement and renovation of concrete structures, such as the anchoring of newly - added components and the repair of structural cracks.


  • Skylight engineering: It can be used to fix the skylight frame and connecting parts, ensuring the stability and safety of the skylight system under various environmental conditions. It is widely applied in skylight projects of high-rise buildings and large commercial buildings.
