[0002] After years of use, the structural performance of bridges gradually deteriorates, and damage occurs in many places. Structural cracks on bridges are caused by external loads, and their distribution and width are related to the external loads. The appearance of such cracks indicates that the structural bearing capacity may be insufficient or there may be other serious problems. In order to reduce safety hazards, timely repairs are necessary.
[0003] When repairing cracks in bridge decks, concrete and reinforcement components are usually used. Existing reinforcement components are mostly fixed and multiple sets of reinforcement components are spliced together, which makes it difficult to reinforce cracks of different depths and widths.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 , Figure 2 and Figure 4As shown, the present invention proposes a bridge and road crack reinforcement structure, including a bridge body 1 and a crack 8. The crack 8 is located on the upper part of the bridge body 1. It also includes a connecting plate 3, a fixed connecting shaft 4, a movable connecting shaft 5, and a fixing bolt 13. A repair groove 2 is provided on the bridge body 1, and the repair groove 2 is located on the upper part of the crack 8. The connecting plate 3 is located on the upper part of the repair groove 2 and is movably connected to the repair groove 2. One end of the fixed connecting shaft 4 is fixedly connected to the connecting plate 3, and one end of the movable connecting shaft 5 is slidably connected to the other end of the fixed connecting shaft 4. A fixing plate 6 is fixedly provided on the other end of the movable connecting shaft 5. A reinforcing rib 12 is fixedly connected to the lower part of the connecting plate 3. A connecting rod 14 is fixedly provided on the upper part of the fixing bolt 13. The upper end of the connecting rod 14 and the lower part of the reinforcing rib 12 are threadedly connected.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the connecting plate 3 is designed with a T-shaped structure. Fixed connecting shafts 4 are fixed to both the left and right sides of the connecting plate 3. A fixing screw 7 is provided on the upper part of the fixing plate 6. The fixing screw 7 is threadedly connected to the fixing plate 6 and passes through the fixing plate 6. The lower end of the fixing screw 7 is threadedly connected to the repair groove 2. The fixing screw 7 is an expansion screw structure used to connect the device and the bridge body 1. A limiting block 11 is fixed to the outer end of the movable connecting shaft 5. A sliding groove 10 is opened inside the fixed connecting shaft 4. A baffle 9 is fixed to the outer end of the sliding groove 10. The movable connecting shaft 5 and the sliding groove 10 are slidably connected. The baffle 9 and the limiting block 11 are in a limiting connection. Both the repair groove 2 and the crack 8 are filled with concrete.
[0022] In practical use, a repair groove 2 is cut at the crack 8 on the bridge body 1. According to the depth of the crack 8, the connecting rod 14 is rotated to extend the fixing bolt 13, the reinforcing rib 12 is aligned with the crack 8, the connecting plate 3 is placed on the crack 8, and the connecting plate 3 is inserted into the crack 8. After adding concrete, it can strengthen and fix cracks 8 at different depths. According to the width of the crack 8, the movable connecting shaft 5 is stretched or shortened from the inside of the fixed connecting shaft 4. The fixing screw 7 is used to fix the fixing plate 6 and the repair groove 2. After fixing, concrete is injected into the repair groove 2 to complete the repair of the crack 8. It can provide auxiliary fixation for cracks 8 of different widths and complete the reinforcement of the bridge body 1. At the same time, metal has a larger coefficient of thermal expansion and contraction than concrete. Setting the fixed connecting shaft 4 and the movable connecting shaft 5 as a sliding connection can reduce the relative movement of the fixing plate 6 and the fixing screw 7 caused by the change in distance between the connecting plate 3 and the fixed connecting shaft 4 due to thermal expansion and contraction. This reduces the damage to the concrete when the device expands and contracts with heat and increases the stability and service life of the fixation.
[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
