Friction enhancement type embedded prestressed anchorage device with annular ribs

The invention discloses a friction enhancement type embedded pre-stressed anchorage device with annular ribs, and relates to the technical field of pre-stressed anchorage devices, the friction enhancement type embedded pre-stressed anchorage device comprises a ribbed barrel and a clamp body arranged in the ribbed barrel, the clamp body comprises a first clamp, a second clamp and a third clamp, and the third clamp, the second clamp and the first clamp are all arranged to be of an arc-shaped structure. According to the friction enhancement type embedded pre-stressed anchorage device with the annular ribs, the friction force effect between the pre-stressed anchorage device and a pre-stressed reinforced component is enhanced, and the integrity of the structure at the anchoring position is effectively improved; a force transmission mechanism between a prestressed tendon and a pre-stressed reinforced component is changed, and is combined with the pre-stressed reinforced component in an embedded mounting mode, and t
