How strong is a chemical anchor bolt?
What is the core strength standard for chemical anchor bolts that comply with national/European standards?
The chemical anchor core advantage lies in
High strength chemical anchor bolts that meet the requirements are mostly made of grade 8.8 or 10.9 carbon steel or 304 or 316 stainless steel, combined with high-performance epoxy agents. After curing, they can form a whole with concrete, stone and other substrates, with strong anchoring force and no expansion stress, and will not cause compression damage to the substrate. They are suitable for concrete substrates with strength of C15 or above.
Chemical anchor bolt Three core application scenarios, load-bearing performance and safety level
（1） Curtain wall installation scenario: lightweight load-bearing, high safety protection
In curtain wall installation, chemical anchor bolts are mainly used to fix the curtain wall keel and hanging parts. They need to withstand the weight of the curtain wall itself, wind loads, and seismic loads, and have high requirements for the stability and pull-out resistance of anchoring. High strength chemical anchor bolts can have a single bolt tensile bearing capacity of 10-50kN (increasing according to different specifications, M8-M24 specifications) and a shear bearing capacity of 5-30kN in curtain wall installation, which can effectively resist the lateral tensile force caused by wind loads and avoid safety hazards such as curtain wall detachment and loosening.
（2） Steel structure fixed scenario: heavy load bearing, anti vibration, anti fatigue
In steel structure fixation (such as factory steel structure, bridge steel structure, support steel structure, etc.), chemical anchor bolts need to withstand the self weight, equipment load, and vibration load of the steel structure, which belongs to heavy-duty anchoring scenarios. The safety level needs to reach C4 safety level to ensure that the anchoring system will not loosen or break due to long-term overload and vibration. In the steel structure scenario, the single bolt tensile bearing capacity can reach 20-80kN, and the shear bearing capacity can reach 15-45kN. For large-sized products such as M20 and M24, the bearing capacity can meet the fixed requirements of heavy-duty steel structures and has excellent fatigue and seismic resistance. It can effectively buffer loads under earthquake action and avoid steel structure collapse.
（3） Equipment fixed scenario: precise load-bearing, anti displacement, anti loosening
In industrial equipment and heavy equipment fixation (such as machine tools, cranes, distribution boxes, etc.), chemical anchor bolts need to withstand the weight of the equipment and the vibration load during operation, ensuring that they will not loosen during long-term operation of the equipment. In the fixed equipment scenario, precise selection can be made based on the equipment load. The single bolt tensile bearing capacity can be flexibly selected according to specifications, and the shear bearing capacity is adapted to the lateral load during equipment operation. At the same time, it has good creep resistance and no obvious deformation at room temperature. It can firmly fix the equipment foundation, avoid equipment displacement and shaking, ensure the normal operation of the equipment, and reduce the occurrence of equipment failures and safety accidents.
