Working Principle of post tensioning wedge
By utilizing the taper of the anchor ring and the prestressed anchor plate, a significant clamping force is generated on the steel strand, creating a strong gripping force. The clamping-type anchor system generally utilizes the frictional resistance between the prestressed anchor plate and the steel strand to secure the steel strand. The porous prestressed anchor plate system, also known as a cluster anchor system, consists of porous prestressed anchor plates, anchor bearing plates (also known as cast iron bellows, anchor seats), helical bars, or steel mesh sheets. This type of anchor is implemented on a multi-porous anchor plate, with each conical hole holding a pair of prestressed anchor plates to clamp a steel strand. Its advantage lies in the fact that the failure of any single steel strand anchorage does not lead to the overall failure of the anchoring system. The number of roots in each bundle of steel strands is not restricted.
