Embodiment 1
[0028] Temporary cables are normally anchored, such as Figures 1 to 4 As shown, the specific anchoring process is as follows:
[0029] The first step is to form a plurality of clip flaps into a removable clip 1 and put it into the groove of the sleeve 2;
[0030] The second step is to pass the prestressed bundle 3 that needs to be stretched through the anchor plate 5, the detachable clip 1, the sleeve 2 and the holes reserved on the special limit plate 7 in turn, and adjust the position of the special limit plate 7. ; The special limit plate 7 has a deep groove, which is used to accommodate the detachable clip 1 with the sleeve 2, and a hole is reserved at the position where the prestressed beam 3 passes through, which is only used for the tension of the prestressed beam 3. process, and can also play the role of a reaction frame.
[0031] The third step is to place the jack on the rear end of the special limit plate 7, and carry out the normal tensioning process;
[0032] ...
Embodiment 2
[0036] Dismantle the anchor. When the temporary cable is used, the anchor needs to be dismantled, such as Figure 5 As shown, the specific unloading process is as follows:
[0037] The first step is to loosen the screw 6, and separate the cover plate 4 and the anchor plate 5 by a distance, so that the groove in the sleeve 2 is no longer in contact with the end raised ring of the detachable clip 1;
[0038] The second step is to place the reaction force seat 8, and put the anchor unloading jack on the reaction force seat 8 at the rear end of the cover plate 4;
[0039] The third step is to perform the overall tensioning when the anchor is unloaded. During tensioning, the cover plate 4 is used to drive the sleeve 2 and the detachable clip 1 to withdraw a certain distance from the anchor hole of the anchor plate 5, and then release it;
[0040]The fourth step is to repeat the operation process of the third step until the cover plate 4 drives the sleeve 2 and the detachable clip ...
Embodiment 3
[0042] Further, another structure of the detachable clip 1 only uses the gap between the two clip flaps to make the raised ring snap into the groove on the inner wall of the sleeve 2, thereby realizing the connection between the sleeve 2 and the removable clip. Disassemble the connection of the clip 1. This connection method has unstable connection. For example, under the external influence of the clip flap, there is only one side of the two clip flaps. At this time, it will not only affect the detachable clip 1 The connection effect with the sleeve 2, and the detachable clip 1 is also easy to cause the effect of cutting the prestressed bundle 3, thus forming a safety hazard. In order to solve this drawback, at the same time, it is ensured that the cover plate 4 can be used to disassemble the removable clip 1 and the sleeve 2 as a whole when the anchor is disassembled, so that the two adjacent clip petals of the removable clip 1 are formed away from one end of the raised ring. ...
