[0002] Bridge construction pedestrian arch bridge anchoring devices are mainly used to fix and support the bridge structure to ensure the stability and safety of the bridge. During the bridge construction process, anchoring devices such as anchor plates and anchor cables are used to fix the various parts of the bridge in place to withstand the weight of the bridge itself and external loads. These anchoring tools help the bridge resist various forces by providing strong pulling and supporting forces, thereby maintaining the stability and integrity of the bridge structure.

[0003] When using anchor plates for anchoring and pulling operations on pedestrian arch bridges, the steel strands are passed through the anchor plates and pushed into the casting holes of the anchoring wall. After the pushing is completed, concrete is poured into the casting holes. During the pouring process, the pressure of the injected concrete will cause the anchor plates to shift. Because the anchor plates are an important part used to fix and support the bridge structure, if the anchor plates move, it may change the expected shape and stress state of the bridge, thereby affecting the overall performance of the bridge and reducing the anchoring effect.

[0020] What needs to be said here is: when using the anchor plate 201 to perform the anchoring and pulling operation of the pedestrian arch bridge, after pushing the anchor plate 201 into the casting hole 102, the support assembly and the telescopic assembly cooperate with each other to fix the pushed anchor plate 201 inside the casting hole 102. By supporting and fixing the anchor plate 201, the force displacement of the anchor plate 201 during the subsequent casting process is avoided, thereby ensuring the overall performance and effect of the bridge anchoring.

[0021] The support assembly is provided in multiple groups on the anchor plate 201, and the multiple groups of anchor plates 201 are arranged in a ring array;

[0022] What needs to be said here is that multiple support components facilitate uniform and efficient support.

[0023] The support assembly includes an installation box 301 fixed to the outside of the anchor plate 201, and a support plate 302 is connected to the installation box 301 through a telescopic assembly. The front side of the support plate 302 is provided with an arc surface 303 for supporting against the casting hole 102, and a driving assembly for driving the telescopic assembly is provided on the installation box 301;

[0024] What needs to be said here is: after the anchor plate 201 is pushed into the casting hole 102, the arc surface 303 on the support plate 302 is abutted against the inner wall of the casting hole 102 through transmission, and the arc surface 303 of the support plate 302 on multiple support components and the inner wall of the casting hole 102 are abutted against each other, so that the pushed-in anchor plate 201 is fixed inside the casting hole 102, and the supporting and fixing effect of the anchor plate 201 can prevent the anchor plate 201 from being offset due to force during the subsequent casting process.

[0025] The telescopic assembly includes two sets of transmission plates 401 symmetrically arranged inside the installation box 301. The transmission plates 401 are slidably connected inside the installation box 301 through a sliding assembly. A connecting rod 402 is arranged between the transmission plates 401 and the lower side of the support plate 302. Both ends of the connecting rod 402 are rotatably connected to the transmission plates 401 and the support plate 302 respectively.

[0026] It should be noted here that: through the driving assembly and the sliding assembly, the two transmission plates 401 after being subjected to force move towards or away from each other. During the movement of the two transmission plates 401, the two sets of connecting rods 402 are used to push the support plate 302 to perform telescopic movement.

[0027] The driving assembly includes a double-threaded rod 501 rotatably connected to the installation box 301, and the threads at both ends of the double-threaded rod 501 are arranged in opposite directions. Threaded sleeves 502 are fixed on the two transmission plates 401, and the two threaded sleeves 502 are respectively meshed with the two ends of the double-threaded rod 501. One end of the double-threaded rod 501 is located outside the installation box 301 and is fixed with a driving pin 503; the sliding assembly includes a plurality of sliding holes 601 opened on the transmission plate 401, and each sliding hole 601 is slidably connected to a guide rod 602, and the guide rod 602 is fixed inside the installation box 301;

[0028] What needs to be said here is: the double-headed threaded rod 501 is driven to rotate by the driving pin 503. During the rotation of the double-headed threaded rod 501, the two threaded sleeves 502 are respectively engaged with the two ends of the double-headed threaded rod 501 to drive the two transmission plates 401 to move under force. During the movement of the two transmission plates 401 under force, the sliding guiding effect of the sliding hole 601 and the guide rod 602 makes the two transmission plates 401 move closer to or away from each other after being subjected to force.

[0029] Working principle: When using the anchor plate 201 to anchor and pull the pedestrian arch bridge, each steel strand 103 is passed through each steel strand hole 202 of the anchor plate 201 in turn. After passing through, the anchor plate 201 is pushed into the casting hole 102 of the anchor wall 101;

[0030] After the anchor plate 201 is pushed into the casting hole 102, the double-threaded rod 501 is driven to rotate through the driving pin 503. During the rotation of the double-threaded rod 501, the two threaded sleeves 502 are respectively meshed with the two ends of the double-threaded rod 501 to drive the two transmission plates 401 to move under force. During the movement of the two transmission plates 401 under force, the sliding guide effect of the sliding hole 601 and the guide rod 602 causes the two transmission plates 401 to move closer to each other after being subjected to force. During the approaching movement, the two sets of connecting rods 402 push the support plate 302 toward the outside of the installation box 301 and make the curved surface 303 on the support plate 302 abut against the inner wall of the casting hole 102. The pushed-in anchor plate 201 is fixed inside the casting hole 102 through the abutment effect of the curved surface 303 of the support plate 302 on multiple support components and the inner wall of the casting hole 102. The supporting and fixing effect of the anchor plate 201 can prevent the anchor plate 201 from being offset during the subsequent casting process, thereby ensuring the overall performance and effect of the bridge anchoring.
