[0091] Examples:
[0092] Such as image 3 As shown, the alloy structural pipe 5 is a steel pipe used for pre-compression-stressed steel bars, and its function is to form the pre-compression method pre-compression-stressed steel bars in more than one quantity, and the center penetrates the steel strand 6 (ie, the tension steel bar) with a jack Tension anchoring, put into the compression zone of the structure to be connected as a whole, and withdraw the steel strand to apply pretension to the structure.
[0093] Clip 1 and anchor ring 2 form a single-hole anchor (that is, an anchor). When the jack tensions the steel strand 6 to relax, the clip 1 retracts with the steel strand 6 and the tapered hole of the anchor ring is wedge. 6 is clamped on the anchor ring 2, and the pressure exerted by the steel strand 6 is also transmitted to the pre-compression-stressed steel bar by the anchor.
[0094]The anchor plate is combined with the gold structure pipe 5 and the anchoring rib 4 in 3 join...
