Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The existing bridge reinforcement components have the following defects:

[0025] Most of the existing bridge reinforcement components are provided with a whole thick reinforcing plate at the position where the bridge is prone to deformation, and the layout is not carried out according to the force conditions at the position. In this way, both the positions with large forces and the positions with less forces are reinforced by the reinforcing plate, which results in too many reinforcement components being provided at the positions with small forces, causing waste of resources, and the integral reinforcing member also has the situation of heavy texture and inconvenient installation.

[0026] In view of the above problems, the applicant has provided a first reinforcing member 2 at a fixed position and a second reinforcing member 3 at a changeable position. The entire first reinforcing member 2 is arranged at the position where the bridge main body 1 needs to be reinforced, and then the second reinforcing member 3 is arranged at the position with large forces, and the layout can be carried out according to the forces, and the overall texture becomes lighter and is installed in sections, improving the installation efficiency. As Figures 1 to 5 shown, the present utility model discloses a bridge reinforcement component, a bridge main body 1, a first reinforcing member 2 is installed at the bottom of the bridge main body 1, and a rectangular through groove 23 extending along its length direction is provided inside the first reinforcing member 2;

[0027] A second reinforcing member 3 is slidably assembled in the rectangular through groove 23, and the upper surface and the lower surface of the second reinforcing member 3 are respectively in contact with the upper and lower side walls of the rectangular through groove 23;

[0028] The driving mechanism is configured to drive the second reinforcement member 3 to slide along the rectangular through groove 23. The driving mechanism includes a mounting plate 41 detachably connected to one end of the first reinforcement member 2. A regulating screw rod 42 is horizontally threadedly connected to the center of the mounting plate 41. One end of the regulating screw rod 42 extending into the rectangular through groove 23 is rotatably installed with a sleeve 44. An embedding block 31 that can be embedded into the sleeve 44 is provided on the second reinforcement member 4, and the sleeve 44 and the embedding block 31 are connected by a connecting member. An auxiliary rotating member 43 is provided at the extending end of the regulating screw rod 42. Through the above design, the second reinforcement member 3 is arranged in the rectangular through groove 23 inside the first reinforcement member 2. The first reinforcement member 2 is arranged at the position of the bridge where deformation is likely to occur, playing the role of the first step of reinforcement. Then, according to the stress situation, the second reinforcement member 3 is arranged at the position with greater stress through the driving mechanism, so as to set further reinforcement at the position with the greatest stress, improving the reinforcement effect. And it is not necessary to set a large number of reinforcement mechanisms at all positions, which can reduce the mass of the overall structure. At the same time, during installation, the first reinforcement member 2 can be installed first, and then the second reinforcement member 3 and the driving mechanism can be assembled, and installed in sections, which is more conducive to the installation process.

[0029] In a preferred embodiment, as Figure 3 shown, the first reinforcement member 2 includes a reinforcing plate 21 connected to the bridge main body 1 and a U-shaped plate 22 connected to the bottom of the reinforcing plate 21. A rectangular through groove 23 is formed between the U-shaped plate 22 and the reinforcing plate 21, and the two are integrally formed. In this way, the inside of the first reinforcement member 2 is hollowed out, the mass is reduced, and the construction cost is saved.

[0030] In a preferred embodiment, as Figure 3 shown, a part of the reinforcing plate 21 extends out of the U-shaped plate 22 on both the inner and outer sides to form ears. Waist-shaped holes 211 are uniformly opened on the ears on both the inner and outer sides of the reinforcing plate 21. A threaded rod 101 is fixedly connected to the bridge main body 1 at the position corresponding to the waist-shaped holes 211. The threaded rod 101 passes through the waist-shaped holes 211 and a locking nut 212 is threadedly assembled on the extending section of the threaded rod 101. Through the above design, the design of the waist-shaped holes 211 can facilitate dealing with design errors, facilitate the penetration of the threaded rod 101, and at the same time can adjust the position of the first reinforcement member 2 within a certain range.

[0031] In a preferred embodiment, as Figure 2 、 4 shown, the second reinforcement member 3 is an I-shaped plate. The upper and lower flange plates of the second reinforcement member 3 are respectively in contact with the upper and lower side walls of the rectangular through groove 23. The embedding block 31 is fixedly connected to the web of the second reinforcement member 3. Through the above design, the strength of the I-shaped plate can meet the requirements, and it is convenient to slide the second reinforcement member 3 into the first reinforcement member 2 for installation.

[0032] In a preferred embodiment, asFigure 5 As shown in the figure, an embedding plate 411 matching the rectangular through groove 23 is provided on one side of the mounting plate 41 facing the first reinforcing member 2. Through the above design, the connection stability between the mounting plate 41 and the first reinforcing member 2 is enhanced, and positioning and assembly are facilitated.

[0033] In a preferred embodiment, as Figure 5 shown in the figure, a threaded groove 412 matching the adjusting screw rod 42 is formed in the center of the embedding plate 411, and the threaded groove 412 penetrates through the entire mounting plate 41. Mounting holes 413 are formed on the inner and outer sides of the mounting plate 41. The threaded groove 412 is used for mounting the adjusting screw rod 42, and the mounting holes 413 are used for connecting the mounting plate 41 with the first reinforcing member 2.

[0034] In a preferred embodiment, as Figure 2 shown in the figure, the connecting member is a bolt pair. First through holes 441 matching the bolts on the bolt pair are formed on the inner and outer side walls of the sleeve 44. Second through holes 311 matching the first through holes 441 are provided on the embedding block 31. After the bolts on the bolt pair pass through the first through holes 441 and the second through holes 311, nuts are threadedly assembled on the protruding ends thereof. The sleeve 44 and the embedding block 31 can be quickly connected together, and then the second reinforcing member 3 is driven to move along the rectangular through groove 23 by the driving mechanism.

[0035] In a preferred embodiment, the auxiliary rotating member 43 is one of a rotating handle and a circular plate, which serves to assist in rotating the adjusting screw rod 42.
