What is the industrial role of high load anchor bolts?

High-load anchor bolts significantly improve tensile and shear strength through special structural design (such as mechanical locking, chemical bonding or bottom expansion structure). Chemical anchor bolts form a rigid bonding layer through chemical adhesives, and the tensile strength can reach tens of kilonewtons to hundreds of kilonewtons. In high-load scenarios (such as bridge construction and high-rise buildings), anchor bolts need to withstand dynamic stresses such as earthquakes and wind loads. Special inverted cone-shaped anchor bolts can maintain a stable connection in a vibrating environment through the mechanical locking of the inverted cone and concrete, combined with the effect of chemical adhesives.
Some applications of high-load anchor bolts in key engineering fields:
1. Curtain walls and steel structures: used to fix curtain wall keels and steel beam bases, bearing wind pressure and self-weight loads
2. Bridges and tunnels: provide reliable connection force in bridge reinforcement and tunnel support, resist traffic vibration and geological stress
3. Nuclear power equipment: fix key equipment such as reactor vessels and steam generators, requiring anchor bolts to maintain high load-bearing capacity and corrosion resistance in high temperature and radiation environments
4. Heavy machinery: such as conveyor belt systems and storage equipment, anchor bolts are required to withstand vibration and impact for a long time
5. Rail transit: fixation between subway tracks and installation of contact network wrist arms, relying on the durability and seismic performance of anchor bolts
6. Disaster prevention engineering: used for the construction of landslide protection equipment and seismic reinforcement of buildings, and the overall stability is improved through the coordinated force of anchor bolts and substrates
