Description

Technical Field

[0001] The utility model relates to the technical field of bridge reinforcement, in particular to an anti-overturning reinforcement device for a single-column pier bridge. Background Art

[0002] Single-column piers are widely used in urban viaducts and highway ramps due to their advantages of saving space under the bridge, visual transparency, simplicity and beauty. However, in recent years, due to the continuous increase in traffic volume and the repeated occurrence of car overloading, the safety problem of single-column piers in resisting overturning has become increasingly prominent. Once the superstructure overturns, it will cause a major safety accident with a huge social impact. Therefore, it is necessary to reinforce the single-column pier bridges to resist overturning.

[0003] To enhance the anti-overturning reinforcement effect of single-column pier bridges, the prior art has made numerous improvements to single-column pier anti-overturning reinforcement devices. For example, patent publication number CN216194137U discloses an anti-overturning reinforcement device suitable for rectangular single-column pier bridges, comprising a steel cap beam arranged along the width of the beam and additional supports symmetrically arranged on both sides of the top of the steel cap beam. The steel cap beam includes a support structure symmetrically arranged on the rectangular single-column pier. The support structure includes a support steel plate, two fixed steel plates, and two T-shaped steel wing plates. This utility model features a novel and reasonable design, a simple structure, and strong practicality. By adding a steel cap beam and arranging two additional supports on both sides of the top of the steel cap beam, the single support is replaced by multiple supports, thereby improving the anti-overturning capacity of the rectangular single-column pier. The support steel plates transfer a portion of the load to the top of the rectangular single-column pier, placing it in a compressive state, reducing the shear force on the waist of the rectangular single-column pier, fully utilizing the compressive performance of the rectangular single-column pier, and ensuring the quality of the rectangular single-column pier itself. The structure is reliable and stable, and the construction is convenient, making it easy to promote and use.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the supporting steel plate is fixed to the side of the single-column pier by anchor bolts, and new bearings are provided on the supporting steel plate to support the bridge. However, in reality, the positions of the newly added bearings to support the bridge are different according to the size of the bridge and the actual overturning state. It is necessary to appropriately adjust the positions of the newly added bearings. Since the bearings have a certain weight, it is more troublesome for the installers to adjust the bearings. In reality, some single-column piers are provided with cap beams. If the newly added bearings are placed on the concrete cap beam, it is necessary to use anchor bolts to fix the position of the newly added bearings. However, since it is necessary to avoid the steel bars on the cap beam when installing the anchor bolts, it is necessary to adjust the position of the newly added bearings and to avoid the steel bars when installing the newly added bearings. It takes a long time to detect and calculate, which reduces the efficiency of the installation of the newly added bearings. Therefore, there is an urgent need in this field to improve the anti-overturning reinforcement device for single-column pier bridges to solve the defects of the existing technology.

[0029] See also Figure 1-Figure 7 , an anti-overturning reinforcement device for a single-column pier bridge comprises a pier column 1 for supporting a bridge body 2, a steel ring 3 is installed on the side of the upper end of the pier column 1, a symmetrical support platform 4 is provided on the side of the steel ring 3, an adjustment frame 5 is provided on the support platform 4, a newly added support 6 is provided in the adjustment frame 5, a first slide groove 7 is opened at the bottom of the adjustment frame 5, an adapted first slider 8 is slidably connected in the first slide groove 7, a first adjusting rod 9 is provided in the first slide groove 7, a symmetrical clamping plate 10 that is adapted to the lower part of the newly added support 6 is fixedly connected to the side of the first slider 8, the first adjusting rod 9 passes through the adjusting frame 5 and extends to the outside, and a first limiting ring 11 is threadedly connected to the side of one end of the first adjusting rod 9 extending to the outside, and the adjusting frame A second slide groove 12 parallel to the first adjustment rod 9 is provided in each of the opposite side walls. A third slide groove 13 is provided on each of the upper and lower side walls of the second slide groove 12. A third slider 15 is provided in each of the two third slide grooves 13. A second slider 14 is provided on the opposite side of the third slider 15 to adapt to the second slide groove 12. A second adjustment rod 16 passes through the second slider 14 and the third slide groove 13. The second adjustment rod 16 is threadedly connected to the second slider 14 and the third slider 15. The ends of the two second adjustment rods 16 abut against the opposite side of the newly added support 6. A second limiting ring 17 is threadedly connected to the side of the second adjustment rod 16. A plurality of mounting plates 18 are provided on the side of the adjustment frame 5, and mounting holes are provided on the mounting plates 18.

[0030] Specific implementation method of this embodiment: The steel ring 3 is installed on the side of the pier 1 through the existing technology, and the newly added support 6 is placed between the two clamping plates 10. When the position of the newly added support 6 needs to be adjusted, the first adjusting rod 9 or the second adjusting rod 16 is rotated according to the direction to be adjusted. When the first adjusting rod 9 is rotated, the first adjusting rod 9 drives the first slider 8 to slide in the first slide groove 7, thereby adjusting the position of the newly added support 6 in one direction. When the newly added support 6 needs to be adjusted in another direction, the second adjusting rod 16 is moved. When the second adjusting rod 16 moves, the second slider 14 and the third slider 15 move in the second slide groove 12 and the third slide groove 13. When the position of the second adjusting rod 16 is adjusted to match the position of the newly added support 6, Select a second adjusting rod 16 and rotate it. One end of the second adjusting rod 16 approaches and is tightly attached to the side of the newly added support 6. When the second adjusting rod 16 continues to be rotated, it will drive the newly added support 6 to move in another direction. After adjusting the position of the newly added support 6, rotate one end of the other second adjusting rod 16 to against the side of the newly added support 6, and tighten the second limiting ring 17 on the side of the second adjusting rod 16 to limit the position of the second adjusting rod 16. At the same time, tighten the first limiting ring 11 to fix the position of the first adjusting rod 9. Of course, fasteners can also be installed between the clamping plate 10 and the newly added support 6 to limit and fix the position of the newly added support 6, which is convenient for the installer to adjust the position of the newly added support 6 to achieve the best support position for the bridge body 2.

[0031] It should be noted that the above-mentioned newly added support 6 is an existing known technology and will not be elaborated on here. When the newly added support 6 needs to be installed on the cap beam, the adjustment frame 5 is fixed on the cap beam through the cooperation of the mounting plate 18 and other fasteners. Since there is no need to precisely fix the position of the adjustment frame 5, the position of the newly added support 6 can be precisely adjusted through the adjustment frame 5, thereby improving the anti-overturning effect of the bridge.
