Wavy Tail Anchor(short Type)

What is a short wave-tail anchor?

A short wave-tail anchor is a special type of wave-tail anchor, named for its short tail. It can be directly connected to a threaded sleeve. It is specifically designed to provide a lifting point or a secure threaded connection for precast concrete components. The wave-shaped design of the reinforcing bar increases the contact area in the load direction, ensuring uniform load distribution and preventing the anchor from being pulled out or the concrete from cracking. It is pre-embedded in the concrete component and used later for:

Lifting: As a load-bearing point for demolding, flipping, transporting, and installing components.

Connection: For reliable connection with other components or the main structure.

Anchoring: To withstand tensile and shear forces generated by wind loads, seismic actions, etc.

Compared to Wavy Tail Anchor(Long Type), short-wave tail anchors have almost no straight section between the reinforcing bar and the threaded sleeve, resulting in a more compact structure while maintaining strength. They are commonly used in precast components where reliable hoisting, anchoring, or temporary support is required during transportation and installation.

Working principle of short wave tail anchors:

Short wave tail anchors evenly distribute the lifting load of precast concrete components to the interior of the component through their wave-shaped steel tail, preventing the component from being pulled out and cracking. They can be securely connected to threaded sockets or lifting rings, providing a stable lifting point. Proper safe working load (SWL), thread compatibility, and compliance with relevant standards ensure safe and efficient lifting operations. During tensile testing, always use a safety factor of at least three.

Specifications of short wave stern anchor

Advantages	Core embodiment
Anchoring efficiency	Short embedment depth and high load-bearing capacity: The wavy surface forms a strong three-dimensional mechanical interlock in the concrete, providing pull-out resistance far exceeding that of traditional straight rods or hook anchors of the same size.
Spatial adaptability	Suitable for thin-walled components: Its small size allows it to be used for thin-walled components with limited space, such as composite floor slabs and precast wall panels, without the need for local thickening for anchoring, thus optimizing the design.
Stress performance	Superior seismic and fatigue resistance: Wave structures can effectively disperse dynamic stress, avoid stress concentration, and have more stable performance under cyclic loading.
Design flexibility	Unlocking design freedom: Providing architects and engineers with reliable and seamless connection solutions when pursuing lightweight, compact prefabricated component designs.
Overall economic efficiency	Optimize life-cycle costs: Although the cost per unit may be slightly higher, it can save on concrete usage, simplify construction, and improve long-term safety, resulting in significant overall benefits.
