Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, an anchorage system for fixing steel strands in a prestressed structure includes an anchor plate 1, an anchor backing plate 3, an anchoring spiral rib 4 and a clip 2; the anchor plate 1 has 12 Circular anchor plate 1 with three oblique holes, installed on the outermost side of the tension side of the steel strand; there are 12 sets of clips 2, which are respectively matched with 12 oblique holes, and each set of clips 2 consists of three clips. Use a hard rubber ring to form a set; the anchor plate 1 is installed directly below the anchor plate 3, and the circular hole in the middle of the anchor plate 3 is nested inside the bellows 5 reserved in the concrete member. The lower spiral rib 4 is installed on the outer periphery of the anchor backing plate 3; the main body of the anchor backing plate 3 is in the form of a tapered cylinder from the...
