Abstract

The invention discloses a split type prestressed anchorage device, relates to the technical field of prestressed anchorage devices, and aims to solve the problem that the recovery rate of steel strands is reduced due to the fact that an existing prestressed anchorage device is difficult to withdraw. The outer wall of an anchor ring is provided with split clamping pieces; the number of the split clamping pieces is three; anchor holes are fixedly formed in the anchor ring; the number of the anchor holes is three; split fastening rings are arranged in the three anchor holes; the number of the split fastening rings is three; a steel strand is arranged in each of the three split fastening rings; a groove is formed in the anchor ring; a rubber pad is fixedly arranged on the inner wall of the groove; two guide rods are fixedly arranged on one side of the anchor ring; second telescopic rods are fixedly arranged on one sides of the two guide rods; a first telescopic rod is arranged in the groove; and one end of the first telescopic rod is fixedly connected with the second telescopic rods.

Description

technical field [0001] The invention relates to the technical field of prestressed anchors, in particular to a split prestressed anchor. Background technique [0002] The prestressed anchor is a kind of anchor, which is suitable for the anchorage used in the prestressed tension of concrete in the process of engineering construction. Generally, it is often used in bridge construction. The positioning is pre-installed, and then concrete is poured, and the two ends of the concrete are buried, that is, the two ends of the bellows, which are the end faces set for the stability of the jack during tension. Anchors can be divided into two categories: (a) Tension end anchors: installed at the end of prestressed tendons and can be tensioned. Anchors are also called prestressed anchors. The so-called anchors are post tensioned structures or components Among them, in order to maintain the tensile force of the prestressed tendon and transfer it to the anchor of mixed tension; (b) Fixed ...
