[0028] Example 1:

[0029] like Figure 1-Figure 3 As shown, the utility model provides a bridge crack reinforcement structure, including: a bridge body, a reinforcing steel plate and a connecting piece, the bridge body includes a fixed steel plate 11 and a casting layer 12 located above the fixed steel plate 11, the casting layer 12 is provided with a filling groove that penetrates in the thickness direction, the reinforcing steel plate is arranged in the filling groove and divides the filling groove into a first space 21 and a second space 22, and a second space 22 is defined between the reinforcing steel plate and the fixed steel plate 11, one end of the connecting piece is connected to the reinforcing steel plate, and the other end of the connecting piece is connected to the fixed steel plate 11; wherein cast fillers are provided in the first space 21 and the second space 22.

[0030] In some embodiments, the bridge body includes two parts: a fixed steel plate 11 (bridge steel frame structure) and a casting layer 12 (usually made of concrete, asphalt or other building materials) located above the fixed steel plate 11. When cracks appear in the casting layer 12, the staff is suitable for expanding the cracks to form a filling groove. The filling groove passes through the casting layer 12 in the thickness direction, that is, the filling groove extends to the fixed steel plate 11.

[0031] The reinforcing steel plate is arranged inside the filling slot, and the reinforcing steel plate divides the filling slot into two first spaces 21 and second spaces 22 separated in the thickness direction. The area between the reinforcing steel plate and the fixed steel plate 11 is the second space 22, that is, the first space 21 is located above the second space 22.

[0032] One end of the connecting member (which can be a bolt, steel bar, etc.) is connected to the reinforcing steel plate, and the other end of the connecting member is connected to the fixed steel plate 11 to ensure that the reinforcing steel plate is firmly fixed in the filling groove. The first space 21 and the second space 22 are filled with cast fillers. The second space 22 is provided with cast fillers to increase the strength and stability of the overall structure. The first space 21 is provided with cast fillers, and the top surface of the cast fillers is suitable to be flush with the top surface of the cast layer 12 to ensure the flushness of the repaired bridge surface and beautify the repaired bridge surface.

[0033] It can be understood that the principle of the above arrangement is to add additional support and strength to the existing bridge structure by expanding the cracks in the casting layer 12 into filling grooves, inserting reinforcing steel plates into the filling grooves, and then using connectors to connect the reinforcing steel plates to the fixed steel plates 11, and finally filling them with casting material.

[0034] It should be noted that the structure in the filling slot is a filling structure. Compared with the traditional filling structure (the traditional filling scheme is to fill the filling slot with poured filler, that is, the traditional filling structure is a single-layer structure, that is, only poured filler), the filling structure of the present application (the filling structure of the present application is a three-layer structure, i.e., cast filler-reinforced steel plate-cast filler) has higher strength and stronger bearing capacity, which improves the structural strength of the repaired bridge, thereby improving the bearing capacity of the repaired bridge. It should be noted that the reinforcing steel plate is also connected to the fixed steel plate 11 by a connector, which ensures the connection strength between the reinforcing steel plate and the fixed steel plate 11, thereby ensuring the connection strength between the filling structure and the fixed steel plate 11. At the same time, the reinforcing steel plate is supported by the connector and the fixed steel plate 11, which can further ensure the bearing capacity of the reinforcing steel plate, thereby further improving the bearing capacity of the filling structure.

[0035] According to the bridge crack reinforcement structure of the present invention, by arranging a reinforcing steel plate and a connecting piece in the filling groove, and the connecting piece is suitable for connecting the reinforcing steel plate with the fixed steel plate 11, the bridge with cracks is repaired, and the structural strength and bearing capacity of the repaired part of the bridge are better, thereby ensuring the quality of the bridge repair.

[0036] According to some embodiments of the present invention, the pouring filler is constructed of MAC-modified asphalt. It is understood that MAC-modified asphalt has better mechanical properties and durability, as well as greater stability, higher elasticity, and stronger adhesion under both high and low temperature conditions. Therefore, after the MAC-modified asphalt is filled into the first and second spaces 21 and 22, it can securely connect the reinforcing steel plate, connector, and fixed steel plate 11. It also securely connects the reinforcing steel plate to the pouring layer 12, ensuring that the entire bridge crack reinforcement structure is stably connected to the pouring layer 12 and the fixed steel plate 11, thereby improving the structural stability of the bridge.

[0037] Therefore, MAC modified asphalt has excellent aging resistance and weather resistance, which can extend the service life of the bridge crack reinforcement structure. In addition, the modified asphalt has high adhesion, which can ensure the close bonding between the reinforced steel plate and the pouring layer 12, reducing the possibility of cracks reopening. Of course, MAC modified asphalt maintains good elasticity and toughness in a wide temperature range, and can adapt to the thermal expansion and contraction of the bridge in different seasons and temperature conditions, reducing stress concentration caused by temperature changes. At the same time, the modified asphalt also has good waterproof properties, which can effectively prevent moisture from invading the interior of the bridge, reducing corrosion and other damage. In particular, MAC modified asphalt has good fluidity during construction, is easy to lay and cure, facilitates construction operations, and can also ensure construction quality.

[0038] Example 2:

[0039] In this embodiment, based on the first embodiment, the inner peripheral wall of the filling groove is provided with a mounting groove extending in the horizontal direction, and the reinforcing steel plate includes: a supporting portion 31 and a connecting portion 32, the projection of the supporting portion 31 in the thickness direction is located in the filling groove, the connecting portion 32 is connected to the supporting portion 31, and at least a portion of the connecting portion 32 protrudes from the supporting portion 31 in the horizontal direction and is located in the mounting groove.

[0040] It is understood that the reinforcing steel plate is divided into a support portion 31 and a connecting portion 32. The projection of the support portion 31 in the thickness direction is located within the filling slot. In other words, the support portion 31 is the main portion directly located within the filling slot and is used to provide the primary support. The connecting portion 32 is connected to the support portion 31 and at least a portion protrudes horizontally from the support portion 31 (i.e., extends outward) and is located within the mounting groove of the filling slot. At least a portion of the connecting portion 32 is located within the mounting groove, which increases the connection area between the reinforcing steel plate and the casting layer 12, thereby better fixing the reinforcing steel plate in the filling slot.

[0041] It is worth mentioning that the bottom wall of the installation groove can also support the connection part 32, thereby further improving the setting stability of the reinforced steel plate, further improving the structural strength and bearing capacity of the filling structure. Moreover, the design of the connection part 32 can make the reinforced steel plate better disperse the stress and avoid the stress concentration phenomenon of the reinforced steel plate, thereby improving the reliability of the entire filling structure and improving the quality of the repaired bridge.

[0042] Example 3:

[0043] In this embodiment, based on the second embodiment, the connecting portion 32 is movably connected to the supporting portion 31. It is understandable that the connecting portion 32 can be selectively moved relative to the supporting portion 31 so that at least a portion thereof protrudes from the supporting portion 31. Therefore, during installation, the connecting portion 32 can be first moved so that its projection in the thickness direction is located within the supporting portion 31, so that the supporting portion 31 can be smoothly placed into the filling groove. Subsequently, the connecting portion 32 is moved so that the connecting portion 32 protrudes from the supporting portion 31 and at least a portion of the connecting portion 32 is inserted into the installation groove, thereby achieving installation of the reinforcement steel plate, improving the installation efficiency of the reinforcement steel plate, and thus improving the efficiency of bridge repair.

[0044] According to some embodiments of the present invention, the side wall of the support portion 31 is provided with a connecting groove 311 extending in the horizontal direction, the connecting groove 311 passes through the support portion 31 in the thickness direction, the inner side wall of the connecting groove 311 is provided with a sliding groove 3111, and the outer side wall of the connecting portion 32 is provided with a slider 321, and the slider 321 can be movably accommodated in the sliding groove 3111.

[0045] In some embodiments, the support portion 31 is provided with a connecting groove 311, which passes through the support portion 31 in the thickness direction, and one end of the connecting groove 311 extends to the side wall of the support portion 31, and the inner wall of the connecting groove 311 is provided with a sliding groove 3111. The connecting portion 32 is movably connected to the sliding groove 3111 through the slider 321 on its own outer wall. The inner peripheral wall of the sliding groove 3111 can limit the outer peripheral wall of the slider 321, so that the slider 321 can move stably along the extension direction of the sliding groove 3111, so that the connecting portion 32 can slide stably relative to the support portion 31.

[0046] It is worth noting that the design of the slide groove 3111 and the slider 321 can achieve a stable supporting and supported relationship between the connecting portion 32 and the support portion 31, so that the force applied to the support portion 31 can be stably transmitted to the inner wall of the installation groove through the connecting portion 32, thereby ensuring the load-bearing capacity of the reinforced steel plate. Of course, after the connecting portion 32 slides and is at least partially accommodated in the installation groove, the space between the connecting portion 32 and the connecting groove 311 can be suitable for pouring filler through, avoiding the need for a separate through hole for pouring filler through, thereby preventing the through hole design from reducing the structural strength of the reinforced steel plate and ensuring the structural strength of the reinforced steel plate.

[0047] According to some embodiments of the present invention, there are multiple connecting grooves 311 , which are spaced apart in the circumferential direction of the support portion 31 , and there are multiple connecting portions 32 corresponding to the connecting grooves 311 .

[0048] In some embodiments, a plurality of connection grooves 311 are provided on the side wall of the support portion 31 , and the plurality of connection grooves 311 are spaced apart in the circumferential direction of the support portion 31 . The number of connection portions 32 is the same as the number of connection grooves 311 , and each connection portion 32 corresponds to a connection groove 311 .

[0049] It can be understood that by arranging multiple connecting grooves 311 in the support part 31, and each connecting groove 311 has a corresponding connecting part 32 to match it, the reinforced steel plate can be slidably connected at multiple positions, so that the force on the reinforced steel plate in all directions is more uniform. At the same time, the design of multiple connecting grooves 311 and connecting parts 32 can disperse stress, so that when the reinforced steel plate is subjected to external loads or temperature changes, the stress can be released at multiple points, thereby avoiding damage to a single connection point due to stress concentration.

[0050] Example 4:

[0051] Based on the first embodiment, this embodiment includes a connecting part including: a connecting rod 41 and a first fastening nut 42. One end of the connecting rod 41 is welded to the fixed steel plate 11, and the other end of the connecting rod 41 passes through the reinforcing steel plate and extends to the first space 21. The first fastening nut 42 is arranged in the first space 21 and is threadedly connected to the other end of the connecting rod 41.

[0052] It can be understood that one end of the connecting rod 41 is fixed to the fixed steel plate 11 by welding to ensure the connection strength and reliability of the connecting rod 41 and the fixed steel plate 11, and the other end of the connecting rod 41 is connected to the first fastening nut 42 through a thread, so as to facilitate the connection of the connecting rod 41 to the reinforcement steel plate, and then facilitate the connection of the reinforcement steel plate to the fixed steel plate 11.

[0053] Therefore, the combination of welding and threaded connection can ensure the stability of the connecting parts when bearing external loads, and prevent loosening between the reinforcing steel plate and the fixed steel plate 11. Moreover, the threaded connection method makes the installation of the reinforcing steel plate more convenient, and the position of the reinforcing steel plate can be adjusted according to actual needs to ensure the reinforcement effect. Of course, the reinforcing steel plate and the fixed steel plate 11 are firmly connected together through the connecting rod 41, which can improve the stability of the entire structure and reduce structural damage caused by external loads. At the same time, the threaded connection provides better construction flexibility, making the installation and adjustment of the reinforcing steel plate easier to control, which helps to ensure construction quality and efficiency.

[0054] According to some embodiments of the present invention, the connecting member further includes: a second fastening nut 43, which is arranged in the second space 22 and is threadedly connected to the connecting member, and the first fastening nut 42 and the second fastening nut 43 are respectively located on both sides of the reinforced steel plate in the thickness direction and respectively stop at the reinforced steel plate.

[0055] It can be understood that by respectively arranging the first fastening nut 42 and the second fastening nut 43 on both sides of the reinforced steel plate, the position of the reinforced steel plate in the thickness direction can be ensured to be more stable, and the reinforced steel plate can be prevented from loosening or moving on any side. Moreover, the first fastening nut 42 and the second fastening nut 43 work together to enable the reinforced steel plate to remain in a predetermined position when subjected to external loads.

[0056] Therefore, by arranging the first fastening nut 42 and the second fastening nut 43 on both sides of the reinforcing steel plate, not only the stability of the reinforced structure is enhanced, but also the flexibility of construction and the reliability of the reinforcement effect are improved. The use of double fastening nuts can ensure that the reinforcing steel plate can maintain a stable position under various working conditions, thereby improving the safety and durability of the entire bridge crack reinforcement structure, and also facilitating construction personnel to carry out precise installation and adjustment.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
