DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the attached Figures 1 to 5 Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0032] As Figures 1 to 3As shown in the figure, a reinforcement device for the aging of bridge support nodes of the present utility model, the reinforcement device 100 includes a load-bearing seat 3, a force-adjusting rod 4 and a force-reinforcing plate 5. The load-bearing seat 3 includes two half-fixed sleeves 31 arranged oppositely. Fixed ear blocks 32 are respectively arranged at the connecting ends on both sides of the half-fixed sleeve 31. Through holes are arranged on the fixed ear blocks 32, and a fixed screw assembly 34 is correspondingly connected between two adjacent fixed ear blocks 32, so as to realize the fixed connection of the two half-fixed sleeves 31. A conical fixing surface 33 is formed axially inside the two half-fixed sleeves 31. When the load-bearing seat 3 is fixedly installed on the bridge support column 1 correspondingly, the conical fixing surface 33 arranged inside the half-fixed sleeve 31 fits with the circumferential conical surface of the bridge support column 1, which can improve the load-bearing capacity of the load-bearing seat 3, prevent the load-bearing seat 3 from moving downward under force, and solve the problems that the existing reinforcement structure needs to drill holes at the support node during installation, and drilling is likely to cause cracking and weak bearing capacity at the support node, etc.

[0033] As Figures 4 to 5 shown, support cantilevers 35 in the same radial direction are respectively arranged on the outer side walls of the two half-fixed sleeves 31, so as to facilitate the fixed reinforcement of the adjacent bridge girders 2 to be reinforced by the two support cantilevers 35 respectively. A positioning screw hole 37 penetrating up and down is arranged at the outer end of the support cantilever 35. A threaded area 41 adapted to the positioning screw hole 37 is arranged on the rod body of the force-adjusting rod 4. The force-adjusting rod 4 is threadedly connected to the support cantilever 35 through the threaded area 41. A driving column 43 is arranged at the lower end of the force-adjusting rod 4, and the driving column 43 can drive the force-adjusting rod 4 to rotate, and then the top elevation of the force-adjusting rod 4 can be adjusted.

[0034] As Figure 4 shown, the force-reinforcing plate 5 is correspondingly rotatably connected to the top end of the corresponding force-adjusting rod 4. The force-reinforcing plate 5 includes a support cross plate 51 and support vertical plates 52 vertically arranged at both ends of the support cross plate 51. The width of the force-reinforcing plate 5 can be set according to requirements. For example Figure 1 for the T-shaped box girder described above, the support cross plate 51 of the force-reinforcing plate 5 correspondingly supports on the bottom surface of the girder web 51, and the support vertical plates 52 at both ends thereof correspondingly clamp on both side walls of the girder web 21, so as to realize the fixed support for the T-shaped box girder. A limiting hole 53 is arranged at the center of the support cross plate 51 of the force-reinforcing plate 5. A fixing column 42 is arranged at the top end of the force-adjusting rod 4 and a connecting member 44 sleeved on the fixing column 42. The connecting member 44 can be rotatably clamped in the limiting hole 53; among them, the connecting member 44 can adopt structures such as bearings and gaskets to realize the fixed limiting function. Rotating the force-adjusting rod 4 can perform meshing lifting adjustment along the support cantilever 35, which is convenient to adjust the force between the force-reinforcing plate 5 and the bridge girder 2 by the lifting of the force-adjusting rod 4, and solves the problem that after the existing reinforcement structure is installed, it is impossible or inconvenient to perform reinforcement force adjustment operations according to the actual situation in the later stage.

[0035] In a preferred embodiment, as Figure 5 shown, on both sides of the connection ends of the two half-fixed sleeves 31, fixed anti-rotation plates 6 are respectively fixedly clamped between two fixed ear blocks 32. The upper end of the fixed anti-rotation plate 6 is higher than the upper end surface of the half-fixed sleeve 31 and can be correspondingly inserted between the connection seams of adjacent bridge girders 2. The two fixed anti-rotation plates 6 can prevent the reinforcement device from rotating with the bridge girder 2 after installation, improving the bearing capacity and service life of the reinforcement device.

[0036] In a preferred embodiment, as Figure 5 shown, on the outer side wall of the half-fixed sleeve 31 below the support cantilever 35, a support rib plate 36 is provided. The support rib plate 36 can form a stable support between the support cantilever 35 and the half-fixed sleeve 31.

[0037] In a preferred embodiment, as Figures 2 to 3 shown, a plurality of positioning surfaces for clamping by a tightening tool are circumferentially provided on the driving column 43, and the number of positioning surfaces can be set according to requirements. For example, if the number of positioning surfaces is six, the driving column 43 can form a regular hexagonal prism structure; when the number of positioning surfaces is five, the driving column 43 can form a regular pentagonal prism structure; the number of positioning surfaces can also be seven, four, three, two, etc. The specific number of positioning surfaces is not limited, and it is appropriate to facilitate the clamping of the rotating tool. It should be noted that the shape of the driving column 43 of the force adjustment rod 4 can be set into a structure adapted to the special tightening operation, not limited to the above structure. By using a special tightening tool to adjust the rotation of the force adjustment rod 4, non-staff can be prevented from adjusting the rotation of the force adjustment rod 4, improving the operation safety of the reinforcement device.

[0038] In a preferred embodiment, as Figure 2 shown, the outer side surface of the fixed ear block 32 is set as a matte surface, thereby increasing the friction between the outer side surface of the fixed ear block 32 and the fixed bolt, preventing the fixed bolt from rotating and loosening.

[0039] The working principle or working method of the present utility model:

[0040] As Figures 1 to 5As shown in the figure, the half-fixed sleeve 31 of the load-bearing seat 3 is correspondingly clamped on the bridge support column 1 and fixed and locked on the bridge support column 1 through the fixing bolt assembly. The downward movement of the load-bearing seat 3 can be prevented by the cooperation between the conical fixing surface 33 of the load-bearing seat 3 and the outer wall conical surface of the bridge support column 1. At the same time, the fixed anti-rotation plate 6 is inserted into the gap between the cross-sections of two adjacent bridge girders 2 to prevent the load-bearing seat 3 from rotating, thus realizing the installation of the reinforcement device without drilling holes and solving the problem that drilling in the prior art easily causes cracking at the support node. At the same time, the bridge girder 2 is limited between the support vertical plates 52 of the force-reinforcing plate 5, so that the force-reinforcing plate 5 transfers the force to the load-bearing seat 3 through the force-adjusting rod 4, thereby realizing the reinforcement after the aging of the bridge support node. When the force-reinforcing plate 5 is lifted and adjusted, the force-adjusting rod 4 is rotated by a tightening tool to engage with the thread of the load-bearing seat 3. The force-adjusting rod 4 can be lifted and adjusted through thread engagement, and then drive the force-reinforcing plate 5 to rise synchronously through the connecting piece 44. An upward force is applied to the bridge girder 2 through the force-reinforcing plate 5, thus realizing the reinforcement force adjustment operation.

[0041] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
