Q: What is a multi-strand anchorage device, and where is it used?
A: A multi-strand anchorage device is a component used to anchor the ends of prestressing tendons (often multiple steel strands) in prestressed concrete structures and to transfer the prestressing forces into the concrete. It is used in applications such as bridges, building structures, hydraulic engineering, and foundation engineering.
Q: What are the key features of this anchorage device?
A: Some of the important features include: reliable fixation of tendons (ensuring effective force transfer), corrosion-resistance thanks to high-quality material and protective treatment, precision manufacturing for consistent performance, and ease of installation to streamline construction.
Q: What standards or parameters should one check before selecting the anchorage device?
A: It is important to review parameters such as the type code (e.g., YJM15), size in mm, length in mm, load capacity in kN, corrosion protection (e.g., hot dipped galvanising), and compliance with standards like ASTM or ISO.
Q: In which structural scenarios are these anchorage devices applicable?
A: They are applicable for: anchoring prestressing tendons in bridges and viaducts (e.g., girders, cable-stayed towers), building structures (columns, beams, slabs), hydraulic structures (dams, spillways), and foundation/underground engineering requiring prestressing.
Q: What should a buyer consider regarding installation and environmental durability?
A: A buyer should check the corrosion protection of the device (especially for outdoor or harsh environments), ensure the device is manufactured with precise dimensions (for reliable fit and performance), and that it is designed for ease of installation (to reduce construction complexity).
