Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a road bridge crack reinforcement structure. Background Technology

[0002] Bridge cracks can be classified into structural cracks and non-structural cracks according to their causes. Structural cracks are caused by the load on the structure exceeding the design limit or the structure itself being insufficient in strength. They are expansive and directly affect the load-bearing capacity of the bridge. Non-structural cracks are caused by the material properties themselves or environmental factors. They do not directly affect the load-bearing capacity of the structure, but may accelerate the corrosion of steel bars and the carbonization of concrete, indirectly endangering the durability of the structure.

[0003] In the reinforcement of bridge cracks, the adhesive plate method is widely used, which is divided into direct bonding and prestressed bonding. Direct bonding uses adhesive to attach the plate to the surface of the component, but it can only bear force after the adhesive has cured. During the curing period, it cannot share the load, and the immediate effect on crack suppression is limited. Therefore, a road and bridge crack reinforcement structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that direct bonding uses adhesive to attach the board to the surface of the component, but the adhesive can only bear the force after it has cured.

The connector is disposed on the outside of the fixing strip for pulling the fixing strip, and the connector cooperates with the fixing member to adjust the tension of the fixing strip.

[0009] Furthermore, the fastener includes multiple pressure plates, which are disposed on the outside of the fixing strip. Multiple fixing rods are provided on the outside of the pressure plates.

[0010] Furthermore, the connector includes a fixing bolt, there are multiple fixing bolts, and each fixing bolt corresponds to a through hole. The fixing bolt has a connecting groove on the side opposite to the fixing strip. A bolt is threaded into the connecting groove.

[0026] like Figures 1 to 5 As shown, a road and bridge crack reinforcement structure includes: a fixing strip 1, which is elongated and has multiple through holes 101 that penetrate through the fixing strip 1; and an installation assembly, which is disposed on the outside of the fixing strip 1 for fixing the fixing strip 1. The installation assembly includes a connector 2 and a fixing member 3. The fixing member 3 is disposed on the outside of the fixing strip 1 for limiting the fixing strip 1, and the connector 2 is disposed on the outside of the fixing strip 1 for pulling the fixing strip 1. The connector 2 works with the fixing member 3 to adjust the tension of the fixing strip 1. Specifically, when reinforcing the crack, the fixing strip 1 is first attached to the bridge surface. Then, the fixing strip 1 is limited by the cooperation of the connector 2 and the fixing member 3 to ensure the stability of the fixing strip 1 during use. Adhesive is filled between the fixing strip 1 and the bridge to further ensure the stability of the fixing strip 1 in contact with the bridge.

[0027] like Figures 1 to 5As shown, the fastener 3 includes a pressure plate 301, and there are multiple pressure plates 301. The pressure plates 301 are located on the outside of the fastener 1. There are multiple fasteners 302 on the outside of the pressure plate 301. Specifically, during use, the fasteners 302 and the pressure plates 301 cooperate to limit the position of the fastener 1, ensuring the stability of the fastener 1 in use. The fasteners 302 are anchored inside the bridge to ensure the stability of the position of the fasteners 302 during use.

[0028] like Figures 1 to 5 As shown, the connector 2 includes multiple fixing bolts 201, each corresponding to a through hole 101. Each fixing bolt 201 has a connecting groove 205 on the side opposite to the fixing strip 1. A bolt 202 is threaded into the connecting groove 205. A protrusion 204 is provided on the outside of the bolt 202, and the protrusion 204 rotates within the through hole 101. A nut 203 is threaded into the outside of the bolt 202, and the nut 203 is located on the outside of the fixing strip 1. Specifically, during use, multiple fixing bolts 201 are first installed one-to-one inside the bridge according to preset positions. The installation depth and firmness of the fixing bolts 201 must meet construction standards. Since the through hole 101 is convex... The wheel-shaped groove is then controlled by rotating the bolt 202 to rotate the protrusion 204 inside the through hole 101. During the rotation, the protrusion 204 interacts with the inner wall of the cam-shaped through hole 101, thereby generating a tensile force on the fixing strip 1. Through this tensile action, it is further ensured that the fixing strip 1 can stably fit against the bridge surface during use, and prestress is applied to the fixing strip 1. After the position and tension of the fixing strip 1 are adjusted, the nut 203 is tightened towards the fixing strip 1 by using the threaded engagement of the nut 203 and the bolt 202, pressing the fixing strip 1 to eliminate the gap between the fixing strip 1 and the bridge surface, achieving a tight fit and ensuring the reinforcement effect.

[0029] like Figures 1 to 5 As shown, a connecting rod 206 is also provided on the outside of the bolt 202. The connecting rod 206 is internally threaded with a limiting pin 207, and the limiting pin 207 is connected to the pressure plate 301. Specifically, after the bolt 202 has rotated, the bolt 202 is limited by the cooperation of the connecting rod 206 and the limiting pin 207 to prevent the bolt 202 from rotating relative to the fixing bolt 201 during use.

[0030] like Figures 1 to 5 As shown, the end of the protrusion 204 is also provided with a control block. Specifically, the shape of the control block can be a block structure such as a hexagon or a square that is compatible with the wrench. In actual operation, the construction personnel can cooperate with the wrench and rotate the control block by turning the wrench, thereby easily adjusting the bolt 202.

[0031] like Figures 1 to 5As shown, the working state of this road and bridge crack reinforcement structure is as follows: When the fixing strip 1 needs to be installed, the fixing rod 302 and the fixing bolt 201 are first installed inside the bridge. Then, glue is applied between the fixing strip 1 and the bridge. Next, the fixing strip 1 is installed by the cooperation of the fixing rod 302 and the pressure plate 301. After the fixing strip 1 is installed, the bolt 202 controls the protrusion 204 to rotate inside the through hole 101. The rotating protrusion 204 cooperates with the through hole 101 to stretch the fixing strip 1, further ensuring the stability of the fixing strip 1 in contact with the bridge. After the fixing strip 1 is stretched, the bolt 202 is limited by the cooperation of the connecting rod 206 and the limiting pin 207. Finally, the nut 203 is used to further press the fixing strip 1 to ensure the stability of the fixing strip 1 during use.

[0032] In summary, this utility model includes: a fixing strip 1, which is elongated and has multiple through holes 101 that penetrate through the fixing strip 1; and an installation assembly, which is disposed on the outside of the fixing strip 1 for fixing the fixing strip 1. The installation assembly includes a connector 2 and a fixing member 3. The fixing member 3 is disposed on the outside of the fixing strip 1 for limiting the fixing strip 1, and the connector 2 is disposed on the outside of the fixing strip 1 for pulling the fixing strip 1. The connector 2 works with the fixing member 3 to adjust the tension of the fixing strip 1. Through the setting of the connector 2 and the fixing member 3, and the cooperation of the fixing bolt 201, bolt 202, nut 203, protrusion 204, connecting groove 205, connecting rod 206, limiting pin 207, pressure plate 301 and fixing rod 302, this utility model can quickly tension the fixing strip 1 during use, avoiding the need for adhesive to cure before it can bear force, and improving the immediate suppression effect on cracks.
