Which advantage do adhesive anchor bolts have over expansion bolts and sleeves?

Adhesive anchor bolts provide several advantages over expansion bolts and sleeves, making them a popular choice in many applications. One key benefit is their ability to be used near the edges of concrete. Unlike traditional expansion anchors, which rely on mechanical engagement with the concrete, adhesive anchors can bond effectively in areas where expansion bolts might compromise the integrity of the material due to the potential for cracking or breaking near edges.

In addition, adhesive anchors allow for closer spacing between anchor bolts. This is important for optimizing the load distribution within a structure, especially when space is limited or when specific load configurations are required. The bonding nature of adhesives permits effective load transfer in tighter arrangements.

Furthermore, adhesive anchors exhibit minimal creep under vibration and dynamic loading. This means they maintain their effectiveness and strength even in environments where constant vibration is present, such as in machinery installations or in structures subject to oscillations. This property contributes to the overall longevity and reliability of the anchorage system.

Considering all these advantages together highlights the comprehensive benefits of adhesive anchor bolts, justifying the assertion that they excel in various aspects compared to expansion bolts and sleeves.
