Therefore, temporary anchoring measures are arranged between the pile caps to eliminate the unbalanced moment of the box girder, so as to ensure the overall stability of the rotation T structure and reduce the construction safety risk. However, in the actual construction, the temporary anchoring measures usually adopt the form of pouring concrete outside the fine rolling threaded steel, and are affected by the gap setting of the supporting legs, the two pile caps are sunk to different degrees, so that the fine rolling threaded steel reinforcement of the pile cap longitudinal anchoring is in compression yielding state, thereby causing the failure of the temporary anchoring measures. At the same time, before the bridge is formally rotated, the temporary anchoring measures need to be easily removed, and after the bridge is rotated, the temporary anchoring measures can be quickly implemented again. Therefore, the temporary anchoring measures can effectively ensure that there is no risk of instability of the whole beam caused by relying on spherical hinge and supporting leg alone in the construction link. It can be seen that the installation and removal of the temporary anchoring measures are extremely important for the construction quality of the rotating bridge. SUMMARY

[0020] As Figures 1-5 ​​​As shown, the utility model relates to a kind of multiple groups of connection adjustable vertical temporary anchoring structure for bridge flat rotation system, which is arranged between the upper bearing platform 2 and the lower bearing platform 3 of bridge flat rotation system, and relative to the four corners of the upper bearing platform 2 before rotation body each arrangement has a set, and single set temporary anchoring structure 1 includes adjusting frame 11, nut 12 and anchoring screw rod 13, wherein, adjusting frame 11 is the main support frame of the temporary anchoring structure, provides overall stability and adjustability;And nut 12 is used to connect anchoring screw rod 13 and adjusting frame 11, allow fine tuning in the construction process, to adapt to different stress and settlement situation;And anchoring screw rod 13 is the connecting part between the upper bearing platform 2 and the lower bearing platform 3, responsible for load transfer and ensure the stability of bridge, i.e. in the corresponding end of the anchoring screw rod 13 anchored with the upper bearing platform 2 and the anchoring screw rod 13 anchored with the lower bearing platform 3 face each other by respective nut 12 adjustably connected on adjusting frame 11. In this way, before rotation body, the upper bearing platform 2 and the lower bearing platform 3 are temporarily anchored by the multiple groups of connection adjustable vertical temporary anchoring structure, then the anchoring screw rod 13 arranged in the upper bearing platform 2 and the anchoring screw rod 13 arranged in the lower bearing platform 3 can be separated by adjusting frame 11 to release the temporary anchoring between the upper bearing platform 2 and the lower bearing platform 3, and after the completion of rotation body of bridge flat rotation system, the anchoring screw rod 13 arranged in the upper bearing platform 2 and another corresponding anchoring screw rod 13 arranged in the lower bearing platform 3 are connected again by adjusting frame 11. By adjusting the nut, the above scheme can realize accurate control of the anchoring screw rod, adapt to the settlement or deformation of the bearing that may occur during construction, thereby ensuring the stability of the structure;And the multiple arrangement forms are arranged with a set of temporary anchoring structure at the four corners of the upper bearing platform before rotation body, so that the whole structure is uniformly stressed, and the potential risk caused by local stress concentration is reduced. The temporary anchoring mechanism plays an important role in bridge flat rotation construction, improves the safety and efficiency of construction, and is a reliable and convenient construction solution.

[0021] In the present embodiment, the anchoring screw rods 13 on both sides of the adjusting frame 11 in the single set temporary anchoring structure 1 are arranged as at least three groups in symmetrical arrangement. In this way, through symmetrical design, the unbalanced moment caused by external force can be effectively offset, the overturning resistance of the bridge during construction is improved, and the construction safety is ensured. The arrangement of at least three groups of anchoring screw rods means that the structure has a certain redundancy, and if one group fails, the other groups can still provide necessary support to ensure the safety of the overall structure.

[0022] In the embodiment, the adjusting frame 11 is composed of multiple vertical plates 111, horizontal plates 112 and reinforced plates 113. The vertical plates 111 serve as the main supporting elements of the adjusting frame 11, providing vertical supporting force for the adjusting frame 11. The height and number of the vertical plates 111 can be adjusted according to actual construction requirements to adapt to different types of bridge designs. A horizontal plate 112 is arranged at the upper and lower ends between two adjacent vertical plates 111. The horizontal plate 112 is arranged between adjacent vertical plates 111 to provide connection and stability, providing lateral stiffness to the adjusting frame 11. The horizontal plate 112 is used for single anchoring screw rod 13 to pass through and cooperate with the nut 12 to fasten the anchoring screw rod 13, providing support for the penetration and fixation of the anchoring screw rod 13. Reinforced plates 113 are arranged at the connection between the vertical plates 111 and the horizontal plates 112, which helps to further enhance the strength and stiffness of the connection between the horizontal plates 112 and the vertical plates 111, preventing deformation or damage caused by uneven stress during construction. This design not only enhances the stability and load-bearing capacity of the adjusting frame structure, but also facilitates construction operations, providing reliable technical support for bridge construction.

[0023] In the embodiment, the through hole for single anchoring screw rod 13 penetration on the horizontal plate 112 adopts a strip-shaped hole. This design can provide more adjustment space for the anchoring screw rod, making it more flexible during installation and adjustment. That is, during construction, due to possible changes in the pile cap settlement or other changes, the strip-shaped hole design allows construction personnel to conveniently adjust and reposition the anchoring screw rod without disassembling the entire frame.

[0024] In the embodiment, the anchoring screw rod 13 is connected with a steel plate 14 at the end away from the adjusting frame 11, forming a larger stress surface. This design not only improves the connection strength between the anchoring screw rod and the upper or lower pile cap, but also effectively disperses the load applied on the screw rod, reducing the risk during construction and ensuring the smooth progress of bridge construction.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application. They should all be included in the scope of the claims of the present application.
