Reversible Cone Chemical Anchor Bolt

Product Parameter

Dual Locking Mechanism of Under-Cone Structural Design

The core competitiveness of under-cone anchor bolts lies in the exclusive dual safety anchoring system, which completely upgrades the single bonding limitation of ordinary chemical anchors. The stepped under-cone tail structure forms a mechanical interlock key after matching with the cured colloid. When bearing tension and shear load, the under-cone structure will produce active wedge extrusion effect on the cured colloid and concrete hole wall, realizing rigid mechanical locking on the basis of chemical adhesive bonding. This dual integration mode of "adhesive bonding + mechanical occlusion" enables the anchor bolt to have ultra-high load redundancy. It can still maintain stable anchoring performance in slightly cracked concrete and long-term alternating vibration environments, avoiding sudden failure risks of ordinary chemical anchors caused by glue aging and bonding attenuation. It is a high-safety anchoring solution for permanent and important building structures.

Stainless Steel Corrosion Resistance & Dynamic Load Adaptability

Targeting long-term structural load and harsh environmental service conditions, our under-cone anchor bolts adopt high-purity 304 and 316 stainless steel materials with customized mechanical properties. Different from ordinary fastener materials, the selected steel has balanced hardness and toughness, excellent anti-fatigue performance and structural stability, and can resist repeated dynamic impact and vibration load without structural creep and fatigue fracture. The overall passivation treatment effectively isolates atmospheric oxidation, coastal salt spray and chemical corrosion, preventing thread rust and structural expansion failure. Matched with high weather-resistant modified epoxy glue, the whole anchoring system has strong anti-aging and UV resistance, ensuring long-term stable structural bearing capacity in outdoor, humid and corrosive engineering environments.

Precision Shaping & Engineering Standard Processing Technology

All Reversible Cone Chemical Anchor Bolts adopt one-piece integral forging and precision die forming process, with strict dimensional control of the core under-cone gradient and step spacing. The bolt body has no welding splicing, ensuring overall structural integrity and uniform force transmission. The thread adopts high-precision rolling molding, with full tooth shape and accurate pitch, ensuring smooth assembly and uniform locking force. The under-cone part is calibrated by professional mold one-time forming, with consistent gradient radian of each product, which ensures uniform extrusion and locking effect after glue curing. Each batch of products undergoes professional tensile destructive test, dynamic fatigue test and dimensional tolerance inspection to ensure that mechanical parameters fully meet national engineering reinforcement standards, with stable batch quality and zero structural hidden dangers.

Professional Construction Process & Working Condition Matching Guidelines

Under-cone anchor bolts are professional structural safety anchors, with standardized construction processes different from conventional fasteners. Before installation, strictly drill holes and completely clean hole wall dust and residue to ensure full adhesion between colloid and concrete. Adopt bottom-up glue injection mode to ensure full hole filling without bubbles. Rotate and insert the anchor bolt at a uniform speed to make the under-cone structure fully contact and fit with the colloid. Strictly follow the curing time specifications; no load-bearing operation is allowed during the curing period. This product is specially suitable for important structural reinforcement, dynamic load equipment and cracked concrete working conditions, with far higher safety factor than ordinary chemical anchors. It is not applicable to temporary fixing and low-load non-structural scenes, avoiding waste of high-performance anchoring performance.
