Description

Technical Field

[0001] The utility model relates to the technical field of anchors, in particular to a multi-hole locking type anchoring device. Background Art

[0002] The prestressed anchor system is a structural system composed of prestressed tendons, anchors and concrete or steel structures, which strengthens the structure through prestressing. In anchor systems such as cable-stayed cables and large-span suspension cables, the prestressed tendons are not buried in the concrete structure. During service, they will be affected by dynamic loads such as wind loads and structural vibration loads. The anchor system is in a fatigue state and there is a risk of anchor failure. In special occasions such as steel structures, the lower end of the prestressed system is affected by gravity, and the anchor needs to add an anti-falling structure to prevent the anchor from scattering during installation.

[0003] Traditional clip-type anchor products are self-anchored by clips, do not have additional locking functions, and do not have the ability to protect under dynamic load environments. The shock-proof anchors used in inclined cables, etc., adopt a single-hole installation structure, which has a complex structure and is inconvenient to install and maintain. Therefore, a multi-hole locking anchor device is proposed. Utility Model Content
