Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] One embodiment provided by this utility model: as follows Figure 1 As shown, a highway expansion joint repair and reinforcement device includes an expansion joint body 1, a reinforcement component 2, a reinforcement component connector 3, a fixing connector 4, and a positioning component fixing nail 5.

[0023] like Figure 2 As shown, for the original, unrepaired highway expansion joint, the expansion joint body 1 is arranged in multiple groups. Each group of expansion joint body 1 is connected by two sets of connecting components. Both sets of connecting components include a single-sided expansion joint 11. The protrusions of the two sets of single-sided expansion joints 11 are inserted into each other. The bottom of the single-sided expansion joint 11 of one set of connecting components is connected to the lower pad plate 12. The bottom of the lower pad plate 12 is provided with a support connecting seat 13. The bottom of the single-sided expansion joint 11 of the other set of connecting components is directly provided with a support connecting seat 13. The two sets of support connecting seats 13 are respectively connected to the two parts at the roadbed cut-off point.

[0024] When the original highway expansion joint body 1 becomes loose vertically or uneven between adjacent expansion joint bodies 1, reinforcement components 2 need to be installed to repair and reinforce the entire expansion joint.

[0025] like Figure 1 and Figure 3 As shown, the reinforcement components 2 are arranged and installed on the corresponding side of the protruding teeth of the single-sided expansion joint 11. The reinforcement components 2 include a protruding edge 21 and a positioning member 22, with two sets of protruding edges 21 provided on one side of the positioning member 22.

[0026] like Figure 4As shown, before installing the reinforcement component 2, a space corresponding to the size of the reinforcement component 2 is first chiseled out on the ground on both sides of the expansion joint body 1 on the road. The vertical surface on the side corresponding to the protrusion tooth of the single-sided expansion joint 11 is exposed, and two sets of slots 111 are opened horizontally at this position; at the same time, holes are opened on the upper surface of the single-sided expansion joint 11.

[0027] like Figure 1 As shown, since the length of the reinforcing component 2 is the same as that of the single-sided expansion joint 11, and the size of the protrusion 21 matches that of the slot 111, when installing the reinforcing component 2, the two sets of protrusions 21 of one set of reinforcing components 2 can be respectively inserted into and connected to the two sets of slots 111 that are close to each other in the two sets of single-sided expansion joints 11.

[0028] like Figure 5 As shown, the slot 111 of the single-sided expansion joint 11 is U-shaped, and includes a vertical slot 1111 and a horizontal slot 1112. The depth of the vertical slot 1111 is greater than the depth of the horizontal slot 1112. Two sets of vertical slots 1111 are provided, symmetrically about the horizontal slots 1112. The area of ​​the vertical slot 1111 is used to connect the fixing connector 4. The symmetrically distributed fixing connectors 4 increase the strength of the connection between the single-sided expansion joint 11 and the reinforcement component 2.

[0029] When the protruding edge 21 of the reinforcing component 2 is inserted into the slot 111 of the single-sided expansion joint 11, the upper surface of the positioning member 22 is at the same horizontal height as the upper surface of the single-sided expansion joint 11. The area of ​​the transverse groove 1112 expands the connection area between the single-sided expansion joint 11 and the reinforcing component 2, increasing the stability of the reinforcing component 2 in fixing the single-sided expansion joint 11.

[0030] like Figure 6 As shown, the opening on the upper surface of the single-sided expansion joint 11 is a hole that runs from top to bottom through the single-sided expansion joint 11 in the area of ​​the vertical groove 1111. The hole opened on the single-sided expansion joint 11 above the vertical groove 1111 is called the upper hole 112 of the groove, and the hole opened on the single-sided expansion joint 11 below the vertical groove 1111 is called the lower hole 113 of the groove. The protruding edge 21 of the reinforcing component 2 is provided with a connecting hole 211 that corresponds to the single-sided expansion joint 11.

[0031] The single-sided expansion joint 11 is fixedly connected to the protruding edge 21 via a fixing connector 4. When the positioning member 22 is tightly inserted into the single-sided expansion joint 11, the edge of the positioning member 22 fits against the single-sided expansion joint 11, the upper hole 112 and the lower hole 113 of the slot correspond to the connecting hole 211, and the central axes of the three are in the same position. The fixing connector 4 can be installed and fixed from top to bottom at the positions of the upper hole 112, the lower hole 113 of the slot, and the connecting hole 211. The fixing of the fixing connector 4 ensures that the single-sided expansion joint 11 and the protruding edge 21 will not loosen.

[0032] like Figure 7As shown, reinforcement components 2 are installed on both sides of the single-sided expansion joint 11. The fixing of one set of reinforcement components 2 to two adjacent sets of single-sided expansion joints 11 ensures that the single-sided expansion joints 11 at adjacent positions always maintain the same height. The two adjacent sets of reinforcement components 2 are fixedly connected by reinforcement component connectors 3, ensuring that the upper surfaces of the two sets of reinforcement components 2 are at the same horizontal level. This ensures that all the arranged sets of single-sided expansion joints 11 are at the same horizontal level, thus forming a stable whole for the entire expansion joint body 1, improving the overall flatness of the expansion joint body 1, and preventing further deformation during long-term road use.

[0033] The positioning component 22 has an upper and lower protruding part on the side away from the single-sided expansion joint 11. An upper hole 221 is opened on the upper protruding part of the positioning component 22, and a lower hole 222 is opened on the lower protruding part of the positioning component 22. The positioning component fixing nail 5 passes through the upper hole 221 and the lower hole 222 of the positioning component from top to bottom, so that the positioning component 22 is fixedly connected to the roadbed.

[0034] Finally, the fixing nail 5 of the positioning component is inserted into the roadbed through the upper hole 221 and the lower hole 222 of the positioning component and fixed. It is ensured that the positioning component 22 is fixed at the same height as the road surface on its upper surface. Finally, concrete or asphalt is poured on the chiseled part other than the reinforcing component 2. The shape of the upper and lower protruding parts of the positioning component 22 and the fixing nail 5 between them increase the contact area of ​​the concrete or asphalt of the reinforcing component 2, which improves the firmness of the fixation of the reinforcing component 2. By fixing the reinforcing component 2 to the roadbed, the firm fixation of the overall expansion joint body 1 is ensured.

[0035] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
