[0002] When the main arch ring of a bridge arch is constructed under the cable-stayed buckle system, a temporary buckle tower / cable tower needs to be set up at each end of the bridge to provide a detailed platform for the buckle cable / back cable. The buckle tower / cable tower is used to balance the tension between the buckle cable and the back cable. Generally, an anchor box is set on the buckle tower / cable tower to achieve force balance. A large number of shaped components need to be processed and high precision is required, which inevitably prolongs the construction period. Now we are looking for a simple and efficient structure to replace the conventional buckle tower / cable tower. Summary of the invention

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Example 1: Figure 1 - Figure 5 As shown, the present invention provides a technical solution: a movable hinge structure at the bottom of a tower, comprising a tower bottom section 1 and a base 4, the tower bottom section 1 is rotatably connected to the base 4, the base 4 comprises a bottom plate 402 and a main board 401, a ring plate 5 is fixedly connected to the surface of the main board 401, a circular hole 9 is opened on the surface of the ring plate 5, a mounting hole 3 is opened on the surface of the tower bottom section 1, hinge shafts 7 are inserted inside the circular hole 9 and the mounting hole 3, there are two groups of main boards 401, the two groups of main boards 401 are symmetrically distributed on both sides of the middle part of the surface of the bottom plate 402, the bottom of the tower bottom section 1 is clamped between the two groups of main boards 401, a flange 8 is fixedly connected to the top of the tower bottom section 1, a stiffening plate 2 is fixedly connected between the flange 8 and the tower bottom section 1, a stiffening plate 2 is fixedly connected to the surface of the main board 401, and the stiffening plate 2 6 is symmetrically distributed on both sides of the middle part of the surface of the main board 401.

[0021] In this embodiment, the bottom of the buckle tower bottom section 1 is inserted between the two main boards 401 on the base 4, and then the hinge shaft 7 is inserted into the mounting hole 3 on the buckle tower and the inside of the circular hole 9 on the ring plate 5 on the main board 401, so that the buckle tower bottom section 1 and the base 4 can be fixed together, and the buckle tower bottom section 1 and the base 4 can rotate forward and backward. On the one hand, it is achieved to reduce the types and number of high-precision stereotyped structure processing and simplify the construction steps of the inclined buckle hanging system. On the other hand, the buckle tower bottom section 1 at the bottom of the buckle tower and the base 4 can rotate forward and backward to achieve self-balancing of the tension of the front and rear steel strands. The flange 8 on the top of the buckle tower bottom section 1 can be used to fix the other structures of the buckle tower with the buckle tower bottom section 1 by bolts. The function of the stiffening plate 2 makes the connection between the flange 8 and the buckle tower bottom section 1 more firmly. The stiffening plate 2 6 set on the main board 401 of the base 4 can improve the connection between the main board 401 and the bottom plate 402 of the base 4. At the same time, it can also avoid the deformation of the main board 401 caused by the shaking of the buckle tower bottom section 1 during use.

[0022] The working principle of this embodiment: when in use, first install the base 4 at the designated position, then insert the bottom of the buckle tower bottom section 1 between the two main boards 401 on the base 4, and then insert the hinge shaft 7 into the mounting hole 3 on the buckle tower and the circular hole 9 on the ring plate 5 on the main board 401, so that the buckle tower bottom section 1 and the base 4 can be fixed together, and the buckle tower bottom section 1 and the base 4 can rotate back and forth, which, on the one hand, reduces the types and number of high-precision stereotyped structure processing and simplifies the construction steps of the inclined buckle hanging system, and on the other hand, the buckle tower bottom section 1 at the bottom of the buckle tower and the base 4 can be movably hinged The structure rotates forward and backward to achieve self-balancing of the tension of the front and rear steel strands, and then the flange 8 on the top of the tower bottom section 1 can be used to fix the other structures of the tower with the tower bottom section 1 by bolts. Under the action of the stiffening plate 2, the connection between the flange 8 and the tower bottom section 1 is made stronger. If the tower bottom section 1 shakes during use, the stiffening plate 6 arranged on the main board 401 of the base 4 can improve the connection between the main board 401 and the bottom plate 402 of the base 4 and also avoid deformation of the main board 401 due to shaking of the tower bottom section 1 during use.
