[0002] Reinforced concrete bridges are a common type of bridge. In addition, diseases such as concrete carbonization, chloride ion corrosion, and steel corrosion further lead to a decrease in the bearing capacity and durability of concrete bridges, greatly shortening the service life of the bridges. The existing reinforcement method is to add adhesive steel plates and composite materials to increase the lateral force of the cracks and improve the bearing capacity of the overall structure. However, when used on small cracks on the outside of the bridge, this method has low practicality and is not flexible enough. Therefore, in order to effectively restore the bearing capacity of the bridge and extend its service life, we have improved its existing reinforcement structure. Summary of the Invention

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1-Figure 7 The bridge crack reinforcement device shown in the figure, which is based on extrusion bridging, includes a bridge body 1, a pressure rod 2 and a movable rod 3, wherein two pressure rods 2 and two movable rods 3 are respectively provided, and a fastening screw 4 is rotatably installed inside the two pressure rods 2. The two pressure rods 2 are located outside the fastening screw 4 and are threadedly engaged with the fastening screw 4. The two pressure rods 2 and the movable rod 3 are respectively erected on both sides of the outside of the bridge body 1, and contact pieces are provided on both sides of the outside of the two pressure rods 2. An insertion shaft 10 is inserted through the lower part of the two movable rods 3, and a rotating seat 5 is rotatably provided at both ends of the outer side of the insertion shaft 10. Positioning support reinforcement pieces are respectively provided on the lower side of the outer side of the rotating seat 5.

[0027] Reference Manual Figure 1 and Figure 2 It can be seen that the pressure rod 2 and the movable rod 3 can leave a distance between them during the rotation of the fastening screw 4, thereby reserving the width of the bridge body 1, and then being erected on the outside of the bridge body 1 for use.

[0028] The positioning support reinforcement members can support the side and bottom surfaces of the bridge body 1 , thereby reinforcing the cracks in the bridge body 1 .

[0029] The contact member includes a U-shaped seat 9 fixedly arranged on one side of the outer side of the pressure rod 2, a rotating shaft is fixedly arranged inside the U-shaped seat 9, a rotating sleeve 21 is rotatably arranged on the outer side of the rotating shaft, a rotating plate 20 is fixedly arranged on one side of the rotating sleeve 21, two embedded rods 24 are symmetrically inserted inside the rotating plate 20, a connecting rod 22 is commonly provided between the two transversely symmetrical embedded rods 24, a strip channel 18 is opened inside the connecting rod 22, a fixed shaft 19 is fixedly provided on the upper side of the outer side of the U-shaped seat 9, a clamping arm 23 is rotatably installed on the outer side of the fixed shaft 19, one end of the clamping arm 23 is movably inserted into the interior of the strip channel 18, and one side of the embedded rod 24 is in contact with the outer wall of the front end of the bridge body 1;

[0030] Reference Manual Figure 2 、 Figure 5 and Figure 6 It can be seen that the rotating sleeve 21 can cause the rotating plate 20 and the embedded rod 24 to rotate to one side of the bridge body 1, so that the embedded rod 24 can be inserted into the front end surface of the bridge body 1, thereby increasing the contact resistance of the pressure rod 2 and thus enhancing the stability of the pressure rod 2;

[0031] When limiting the rotating plate 20 , the clamping arm 23 can be rotated and placed into the strip channel 18 inside the two connecting rods 22 , and then clamped on one side of the rotating plate 20 to prevent the rotating plate 20 from rotating.

[0032] The positioning support reinforcement includes two clamping rods 14 extending on both sides of the outer side of the rotating base 5 respectively, and a moving base 13 is slidably installed on the outer side of the two clamping rods 14. A supporting plate 6 is slidably inserted into the lower side of the outer side of the moving base 13. A sliding member is provided inside one side of the moving base 13. The sliding member includes a sliding column 8 slidably installed inside one side of the moving base 13. One end of the sliding column 8 passes through the interior of the moving base 13, and a sleeve 12 is rotatably installed on the upper side of the sliding column 8. A plurality of clamping holes 17 are opened on both sides of the outer surface of the sleeve 12.

[0033] Reference Manual Figure 3 and Figure 4 It can be seen that the protrusion of the clamping rod 14 slides with the movable seat 13, thereby allowing the movable seat 13 to drive the lower end supporting plate 6, the sliding column 8, and the sleeve 12 to move;

[0034] The sleeve 12 is rotatably set above the outer side of the sliding column 8. When the upper surface of the triangular plate 16 contacts the bottom surface of the bridge body 1, the side with the clamping hole 17 can be rotated to the position of the clamping column 11, and then the clamping column 11 can limit the movable seat 13 and the sliding column 8 at a later time.

[0035] A triangular plate 16 is fixedly provided on the upper surface of the supporting plate 6 and on the side away from the sliding column 8. The surface of the triangular plate 16 is provided with a wear-resistant layer. Extension plates 7 are fixedly provided on the outer surfaces of both sides of the movable seat 13. The purpose of arranging the extension plates 7 on both sides of the movable seat 13 and the triangular plate 16 on the supporting plate 6 is to increase the contact area with the crack, thereby ensuring that the wall structure at the crack is positioned, reducing the problem of peeling and falling of the concrete structure due to cracks in the later stage.

[0036] Fixed cylinders 15 are fixedly provided on the outer surfaces of both sides of the rotating base 5. Elastic components are provided inside the two sets of fixed cylinders 15. The elastic components include a clamping column 11 that is slidably inserted into the interior of the fixed cylinder 15. A limit ring 26 is fixedly sleeved on the outside of the clamping column 11. A spring 25 is sleeved inside the fixed cylinder 15 and on the outside of the clamping column 11. The end of the clamping column 11 away from the fixed cylinder 15 is set to a smooth angle.

[0037] Reference Manual Figure 7 It can be seen that when the movable seat 13 fits the crack on the side wall of the bridge body 1, the sleeve 12 moves to the inside of the rotating seat 5, and the outer surface of the sleeve 12 gradually squeezes the clamping column 11 inside the fixed tube 15. Then the clamping column 11 squeezes the spring 25 inside the fixed tube 15 through the limiting ring 26, and the clamping column 11 itself also moves toward the inside of the fixed tube 15, causing the clamping hole 17 of the sleeve 12 to be locked with the clamping column 11, and the spring 25 is reset, locking the sleeve 12 firmly inside the rotating seat 5.

[0038] Working principle: When in use, the fastening screw 4 can be rotated according to the width of the bridge body 1, so that the spacing between the pressure rod 2 and the movable rod 3 can meet the installation requirements at the place where the cracks are opened on the outside of the bridge body 1. After the installation is completed, the rotating plate 20 on the outside of the pressure rod 2 is rotated to the front end of the bridge body 1, and the embedded rod 24 inside the rotating plate 20 can penetrate the front end surface of the bridge body 1. Then, the two connecting rods 22 are positioned through the clamping arm 23, and the clamping arm 23 penetrates into the strip channel 18 inside the two connecting rods 22 to locate the position of the rotating plate 20. In this way, the connection strength between the pressure rod 2 and the bridge body 1 can be enhanced, and the position of the rotating seat 5 corresponds to the crack of the bridge body 1. The movable seat 1 3 and the extension plate 7 fit in the outer crack of the bridge body 1, and the sliding column 8 is lifted up after the position of the moving seat 13 is determined, so that the supporting plate 6 and the triangular plate 16 fit in the bottom surface of the bridge body 1. When the moving seat 13 approaches one side of the bridge body 1, the sleeve 12 can gradually slide into the inside of the rotating seat 5. The outer surface of the sleeve 12 will squeeze the clamping column 11 inside the fixed cylinder 15, prompting the clamping column 11 to squeeze the spring 25 inside the fixed cylinder 15 through the limiting ring 26. The clamping column 11 itself also moves toward the inside of the fixed cylinder 15, causing the clamping hole 17 of the sleeve 12 to abut against the clamping column 11, and the spring 25 is reset to firmly lock the sleeve 12 inside the rotating seat 5. In this way, reinforcement can be performed at the crack to prevent the concrete structure at the crack from peeling off.
