Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A reinforcement bracket for municipal roads and bridges includes:

[0026] The main body includes two sets of hoop plates 1. One set of hoop plates 1 has a first stiffening rib 11 fixedly connected to its surface, and the other set of hoop plates 1 has a second stiffening rib 12 fixedly connected to its surface. Bolt assemblies 13 are installed on the surfaces of the first stiffening rib 11 and the second stiffening rib 12. Steel brackets 14 are installed on the surface of the hoop plates 1. The first stiffening rib 11 and the second stiffening rib 12 are the same size. The first stiffening rib 11 and the second stiffening rib 12 can be connected and fixed by the bolt assembly 13, thereby realizing the connection between the two sets of hoop plates 1 and the concrete pier. By installing the reinforcement bracket on the bridge, it can play a role in bearing and transmitting loads, resisting deformation, providing stability and stiffness, dispersing loads and maintaining the integrity of the structure. The steel brackets 14 play a role in supporting and transmitting loads.

[0027] The positioning mechanism includes a fixed plate 2, which is fixedly connected to the surface of the first stiffening rib 11. The surface of the fixed plate 2 has a slot 21 and a connecting rod 22 is installed on the surface of the fixed plate 2. One end of the connecting rod 22 is fixedly connected to a pull plate 23, and the other end of the connecting rod 22 is fixedly connected to a partition plate 24. One side of the partition plate 24 is fixedly connected to a support spring 25, and the other side of the partition plate 24 is fixedly connected to an insertion rod 26. The surface of the second stiffening rib 12 has an insertion hole 27. Under the action of the pull plate 23, the connecting rod 22 can be pulled, thereby achieving the movement of the support spring 25 and the insertion rod 26 under the connection of the partition plate 24.

[0028] Furthermore, the fixed plate 2 has a U-shaped cross-section. The two ends of the fixed plate 2 are fixedly connected to the surface of the first stiffening rib 11. The connecting rod 22 is engaged and connected to the surface of the fixed plate 2 through the slot 21. The two sides of the partition plate 24 are attached to the inner surface of the fixed plate 2. The partition plate 24 can be installed through the fixed plate 2, thereby enabling the installation of the connecting rod 22, the support spring 25 and the insertion rod 26.

[0029] Furthermore, one end of the support spring 25 is fixedly connected to the surface of the partition plate 24, and the other end of the support spring 25 is abutted against the inner surface of the fixed plate 2. The support spring 25 is sleeved on the surface of the connecting rod 22, and the insertion rod 26 is inserted into the surface of the insertion hole 27. Under the action of the support spring 25, a supporting force can be applied to the surface of the partition plate 24, and it always tends to move towards the insertion hole 27. With the connection of the insertion rod 26 and the insertion hole 27, the connection of the first stiffening rib 11 and the second stiffening rib 12 can be realized, and the holes of the mounting bolt assembly 13 on their surfaces can be aligned to achieve the positioning effect.

[0030] Furthermore, there are two sets of insertion holes 27. One set of insertion holes 27 is opened on the surface of the first stiffening rib 11, and the other set of insertion holes 27 is opened on the surface of the second stiffening rib 12. The diameter of the insertion holes 27 is the same as the diameter of the insertion rod 26. The insertion rod 26 can be installed through the insertion holes 27, and the insertion rod 26 penetrates the surface of the first stiffening rib 11 and the second stiffening rib 12 under the action of the two sets of insertion holes 27.

[0031] Furthermore, the surface of the steel bracket 14 is provided with a connecting mechanism, which includes a connecting plate 3. The connecting plate 3 is fixedly connected to the surface of the steel bracket 14. A fixing block 31 is fixedly connected to the surface of the connecting plate 3. A connecting hole 32 is opened on the surface of the connecting plate 3. A through hole 33 is opened on the surface of the fixing block 31. A threaded rod 34 is fixedly connected to the surface of the hoop 1. A nut 35 is installed on the surface of the threaded rod 34. One side of the connecting plate 3 is fixed to the steel bracket 14, while the other side arc-shaped abuts against the outside of the hoop 1. The connection between the hoop 1 and the steel bracket 14 can be realized through the connecting plate 3.

[0032] Furthermore, the connecting plate 3 is abutted against the outer surface of the hoop plate 1. Two sets of fixing blocks 31 and connecting holes 32 are provided. The two sets of fixing blocks 31 are installed on both sides of the connecting plate 3, and the two sets of connecting holes 32 are opened on both sides of the connecting plate 3. The diameter of the through hole 33 is the same as the diameter of the connecting hole 32. The fixing block 31 and the nut 35 are in a planar shape, which makes the nut 35 more firmly and tightly connected. The threaded rod 34 can be installed through the connecting hole 32 and the through hole 33.

[0033] Furthermore, the threaded rod 34 is inserted into the surfaces of the connecting hole 32 and the through hole 33. One end of the threaded rod 34 is fixedly connected to the surface of the hoop plate 1, and the other end of the threaded rod 34 is threadedly connected to the inner surface of the nut 35. The nut 35 is abutted against the surface of the fixing block 31. The threaded rod 34 passes through the surfaces of the connecting plate 3 and the fixing block 31 through the connecting hole 32 and the through hole 33. With the connection of the threaded rod 34 and the nut 35, the steel bracket 14 can be disassembled and assembled.

[0034] Working principle: When the reinforcement bracket is connected to the bridge concrete pier, the first stiffening rib 11 and the second stiffening rib 12 abut against each other and move relative to each other. The insertion rod 26 is squeezed by the second stiffening rib 12 and moves towards the fixed plate 2, so as to drive the partition plate 24 to slide on the inner surface of the fixed plate 2. The support spring 25 is in a compressed state. When the insertion holes 27 opened on the first stiffening rib 11 and the second stiffening rib 12 are aligned, the insertion rod 26 is inserted into the insertion hole 27 under the supporting force applied by the support spring 25, so as to realize the movement limit of the first stiffening rib 11 and the second stiffening rib 12 and accurately align the holes of the mounting bolt assembly 13.

[0035] Before using the reinforcement bracket, first install the steel bracket 14 and place the connecting plate 3 on the hoop plate 1, so that the threaded rod 34 is inserted into the connecting hole 32 and the through hole 33 in sequence and passes through the surface of the connecting plate 3 and the fixing block 31. Then, align the inner side of the nut 35 with the threaded rod 34 and rotate it so that the nut 35 moves on the threaded rod 34 through the thread and abuts against the surface of the fixing block 31 after tightening, so as to complete the installation of the steel bracket 14 and splice it with the hoop plate 1.
