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 the force transmission mechanism of end concentrated force is changed into a friction force transmission mechanism in the length direction of the anchorage device and a mechanical anchoring mechanism provided by the annular rib; the phenomenon that a traditional prestressed anchorage device causes large stress concentration to the end of a structural part is effectively improved.
本发明公开了一种带有环状肋的摩擦增强型埋置式预应力锚具，涉及预应力锚具技术领域，包括带肋筒体和设置在带肋筒体内部的夹具主体，夹具主体包括夹具一、夹具二和夹具三，夹具三、夹具二和夹具一均设置为圆弧形结构。本发明采用上述结构的一种带有环状肋的摩擦增强型埋置式预应力锚具，加强了预应力锚具与被预应力加固构件之间的摩擦力作用，有效提高了锚固处结构的整体性；改变了预应力筋与被预应力加固构件之间的传力机制，通过埋置安装的方式与被预应力加固构件进行结合，将端部集中力这种传力机制改为沿着锚具长度方向的摩擦力传力机制以及环状肋提供的机械锚固机制，有效改善传统预应力锚具对结构件端部造成的较大应力集中现象。
