Description

Technical Field

[0001] This application relates to the field of road and bridge maintenance technology, and in particular to a structure for reinforcing cracks in a cap beam. Background Technology

[0002] Over long-term use, roads and bridges experience gradual changes in structural performance due to various natural environmental factors and vehicle loads. Concrete, as the primary material in bridge structures, degrades with age, leading to cracks. This not only affects the bridge's appearance but, more importantly, reduces key performance indicators such as structural load-bearing capacity, durability, and waterproofing, ultimately threatening the bridge's safe use and normal operation. Therefore, the maintenance and reinforcement of roads and bridges are crucial for ensuring their long-term stable operation.

[0003] Currently, the common method for reinforcing cracked cap beams is to bond steel plates. This involves attaching steel plates to the surface of the cap beam using an adhesive, thereby increasing the load-bearing capacity of the cap beam by utilizing the strength of the steel plates, alleviating the cracking problem, and improving the stress condition of the cap beam.

[0004] However, in the steel plate bonding reinforcement method, the bond between the steel plate and the cap beam is easily affected by environmental factors and time, which can lead to a decrease in the bonding effect or even the steel plate falling off, thereby reducing the reinforcement effect.

[0005] Among the aforementioned related technologies, there is a drawback: the reinforcement reliability of the cap beam using steel plates is not good. Utility Model Content

[0006] To improve the problem of poor reliability of steel plate reinforcement for cap beams, this application provides a cap beam crack reinforcement structure.

[0007] A structure for reinforcing cracks in a cap beam includes: a first mounting plate, a first side of which is used to connect to a first side of the cap beam, and the first side of the first mounting plate is provided with a plurality of first grooves; a second mounting plate, a first side of which is used to connect to a second side of the cap beam; a first connecting plate, one end of which is connected to the first mounting plate, and the first connecting plate and the second mounting plate are parallel and spaced apart; a fastening assembly, which connects the first connecting plate and the second mounting plate, and is used to apply prestress to the second mounting plate and the first connecting plate; and an adhesive layer, which is disposed on the first side of the first mounting plate and the first side of the second mounting plate, the side of the adhesive layer near the first mounting plate filling the first grooves, and the adhesive layer being used to bond the first mounting plate to the first side of the cap beam, and the second mounting plate to the second side of the cap beam.

[0008] By adopting the above technical solution, the first mounting plate and the second mounting plate are respectively used to connect to both sides of the cap beam. The several first grooves on the first mounting plate can increase the contact area with the adhesive layer, so that the adhesive layer can adhere better and enhance the connection stability between the first mounting plate and the first side of the cap beam. The first connecting plate connects the first mounting plate and is set parallel to and spaced apart from the second mounting plate, providing lateral support and connection for the entire reinforcement structure. The fastening assembly connects the first connecting plate and the second mounting plate and applies prestress to them, which can tighten them, so that the reinforcement structure fits tightly against the cap beam, improves the reinforcement effect, prevents further crack expansion, and improves the load-bearing capacity, durability and waterproofness of the cap beam. At the same time, the cooperation between the adhesive layer and the first groove can realize the limiting effect of the first mounting plate, reducing the risk of crack expansion.

[0009] Optionally, the first side of the second mounting plate is provided with a plurality of second grooves, and the adhesive layer fills the second grooves on the side of the second mounting plate closest to the second mounting plate.

[0010] By adopting the above technical solution, several second grooves are provided on the first side of the second mounting plate, so that the side of the adhesive layer near the second mounting plate can fill these second grooves. On the one hand, this increases the contact area between the adhesive layer and the second mounting plate, enhances the friction and interlocking force between the two, and thus improves the connection stability between the adhesive layer and the second mounting plate. On the other hand, the second grooves can play a certain limiting role, preventing the adhesive layer from shifting or sliding under force, further ensuring that the second mounting plate and the second side of the cap beam are firmly and reliably connected through the adhesive layer, and improving the reinforcement effect and stability of the entire cap beam crack reinforcement structure.

[0011] Optionally, the fastening assembly includes a plurality of bolts.

[0012] By adopting the above technical solution, using bolts as fastening components to connect the first connecting plate and the second mounting plate, prestress can be applied to the second mounting plate and the first connecting plate, thereby effectively reinforcing the cracks in the cap beam.

[0013] Optionally, the gap between the first connecting plate and the second mounting plate is filled with adhesive.

[0014] By adopting the above technical solutions, the integrity and stability of the entire reinforcement structure can be enhanced, the reinforcement effect on the cracks in the cap beam can be improved, and the structural bearing capacity, durability and waterproofing of the cap beam can be improved.

[0015] Optionally, it further includes a second connecting plate, a first rib, and a second rib. The first end of the second connecting plate is connected to the top of the second mounting plate, and the second end of the second connecting plate extends away from the first connecting plate. The two adjacent sides of the first rib are respectively connected to the first mounting plate and the first connecting plate, and the two adjacent sides of the second rib are respectively connected to the second mounting plate and the second connecting plate.

[0016] By adopting the above technical solution, the second connecting plate is connected to the top of the second mounting plate and extends away from the first connecting plate, which can increase the lateral stability of the structure and help to distribute the force; the first rib connects the first mounting plate and the first connecting plate, which enhances the connection strength between the first mounting plate and the first connecting plate, improves the overall structural stability of the two, and can better withstand external loads; the second rib connects the second mounting plate and the second connecting plate, which strengthens the connection between the second mounting plate and the second connecting plate, further improves the stability of the entire reinforced structure, effectively prevents relative displacement or deformation between the components, and thus enhances the reinforcement effect on the cracks in the cap beam.

[0017] Optionally, it also includes a sleeve assembly, which includes two sleeve pieces, each sleeve piece covering one end of the gap.

[0018] By adopting the above technical solution, the two sleeves are respectively installed at both ends of the gap between the first connecting plate and the second mounting plate, which can prevent the adhesive filling the gap from overflowing excessively, ensure that the adhesive can fully fill the gap and effectively bond the first connecting plate and the second mounting plate. At the same time, the sleeves can also protect the gap and the internal adhesive, avoiding damage or impact from external factors, thereby improving the overall stability and reinforcement effect of the cap beam crack reinforcement structure.

[0019] Optionally, the top of the first connecting plate and the top of the second connecting plate are flush, the sleeve is a groove with an opening on one side facing the gap, the top of the sleeve is mounted on the upper side of the first connecting plate and the second connecting plate, the first side of the sleeve is located on the side of the first connecting plate away from the second mounting plate, and the second side of the sleeve is located on the side of the second mounting plate away from the first connecting plate.

[0020] By adopting the above technical solution, the sleeve is groove-shaped with the opening facing the gap. The top is mounted on the upper side of the first and second connecting plates, which are flush with each other. The two sides are respectively located on the outer side of the first connecting plate and the second mounting plate. It can cover both ends of the gap, play a protective role, and prevent the adhesive in the gap from being affected by external factors.

[0021] Optionally, one bottom end of the sleeve abuts against the first mounting plate and the second mounting plate, and the other bottom end of the sleeve extends away from the first mounting plate and the second mounting plate, so that the sleeve covers the end of the gap and can fill the upper bottom side of the sleeve when adhesive is applied.

[0022] By adopting the above technical solution, one end of the sleeve abuts against the first and second mounting plates, ensuring the stability of the sleeve in the installation position and preventing displacement. The other end of the sleeve extends away from the first and second mounting plates and covers the gap end, effectively protecting the gap end from external factors such as dust and moisture, which could reduce the adhesive performance. When applying adhesive, the adhesive fills the upper side of the bottom of the sleeve, further enhancing the sealing and connection strength between the sleeve and the mounting plate, improving the stability and reliability of the entire reinforcement structure, and better reinforcing the cracks in the cap beam.

[0023] Optionally, the first side of the sleeve is horizontally spaced from the first connecting plate, and the second side of the sleeve is horizontally spaced from the second mounting plate.

[0024] By adopting the above technical solution, the first side of the sleeve is horizontally spaced from the first connecting plate, and the second side of the sleeve is horizontally spaced from the second mounting plate. This arrangement can prevent the sleeve from directly contacting the first connecting plate and the second mounting plate, thus preventing damage to the first connecting plate and the second mounting plate during installation or use. At the same time, the horizontal spacing forms a certain buffer space, which can reduce the impact of external factors on the connection between the sleeve and the first connecting plate and the second mounting plate, improve the stability and durability of the overall structure, and facilitate the maintenance and repair of the sleeve, the first connecting plate and the second mounting plate in the later stage. Furthermore, the horizontal spacing not only facilitates the installation of the sleeve, but also allows the adhesive to overflow and fill the first and second sides during glue injection, thereby achieving a reliable limiting effect through the solidified adhesive.

[0025] Optionally, the first mounting plate, the first connecting plate, the first rib, the second mounting plate, the second connecting plate, and the second rib are all connected by bolts.

[0026] By adopting the above technical solution, the connection reliability of this structure can be improved.

[0027] In summary, this application includes at least the following beneficial technical effects:

[0028] The first mounting plate and the second mounting plate are used to connect to both sides of the cap beam, respectively. Several first grooves on the first mounting plate can increase the contact area with the adhesive layer, allowing the adhesive layer to adhere better and enhancing the connection stability between the first mounting plate and the first side of the cap beam. The first connecting plate connects the first mounting plate and is set parallel to and spaced apart from the second mounting plate, providing lateral support and connection for the entire reinforcement structure. The fastening assembly connects the first connecting plate and the second mounting plate and applies prestress to them, which can tighten them, making the reinforcement structure fit tightly against the cap beam, improving the reinforcement effect, preventing further crack expansion, and enhancing the load-bearing capacity, durability, and waterproofness of the cap beam. At the same time, the cooperation between the adhesive layer and the first grooves can limit the position of the first mounting plate and reduce the risk of crack expansion.

[0042] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0044] like Figure 1 As shown in the embodiment of this application, a beam crack reinforcement structure (hereinafter referred to as "reinforcement structure") is disclosed. The reinforcement structure includes a first mounting plate 11, a second mounting plate 21, a first connecting plate 12, fastening components, and an adhesive layer 41.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the first mounting plate 11 and the second mounting plate 21 are respectively used to connect to both sides of the cap beam. The first side of the first mounting plate 11 is used to connect to the first side of the cap beam, and the first side of the second mounting plate 21 is used to connect to the second side of the cap beam. The first side and the second side of the cap beam are adjacent to each other. One end of the first connecting plate 12 is connected to the first mounting plate 11 and is perpendicular to it. The first connecting plate 12 and the second mounting plate 21 are parallel and spaced apart, providing lateral support and connection for the entire reinforcement structure.

[0046] The fastening assembly connects the first connecting plate 12 and the second mounting plate 21. The fastening assembly applies prestress to the second mounting plate 21 and the first connecting plate 12 to achieve lateral prestress, tightening both and ensuring the reinforced structure fits tightly against the cap beam, improving the reinforcement effect, preventing further crack propagation, and enhancing the cap beam's load-bearing capacity, durability, and waterproofing. An adhesive layer 41 is located on the first side of the first mounting plate 11 and the first side of the second mounting plate 21. The first side of the first mounting plate 11 has several first grooves 111. The adhesive layer 41 fills the first grooves 111 on the side closest to the first mounting plate 11. The adhesive layer 41 formed by the injection of adhesive is used to bond the first mounting plate 11 to the first side of the cap beam, and the second mounting plate 21 to the second side of the cap beam. The several first grooves 111 on the first mounting plate 11 increase the contact area with the adhesive layer 41, allowing the adhesive layer 41 to adhere better and enhancing the connection stability between the first mounting plate 11 and the first side of the cap beam. Meanwhile, the solidified adhesive layer 41, in conjunction with the first groove 111, can limit the position of the first mounting plate 11, reducing the risk of crack expansion.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the fastening assembly includes a plurality of bolts 31. Using the bolts 31 as a fastening assembly to connect the first connecting plate 12 and the second mounting plate 21 allows prestress to be applied to the second mounting plate 21 and the first connecting plate 12, effectively reinforcing the cracks in the cap beam. Specifically, the bolts 31 can be M20 high-strength bolts.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the first side of the second mounting plate 21 is provided with a plurality of second grooves 211, and the side of the adhesive layer 41 near the second mounting plate 21 is filled with the second grooves 211. Providing a plurality of second grooves 211 on the first side of the second mounting plate 21 allows the side of the adhesive layer 41 near the second mounting plate 21 to fill these second grooves 211 during adhesive injection. This increases the contact area between the adhesive layer 41 and the second mounting plate 21, enhancing the friction and interlocking force between them, thereby improving the connection stability between the adhesive layer 41 and the second mounting plate 21. Furthermore, the second grooves 211 can act as a certain limiting force, preventing the adhesive layer 41 from shifting or sliding under stress, further ensuring a firm and reliable connection between the second mounting plate 21 and the second side of the cap beam through the adhesive layer 41, thus improving the reinforcement effect and stability of the entire cap beam crack reinforcement structure.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the gap 5 between the first connecting plate 12 and the second mounting plate 21 is filled with adhesive. The reserved width of the gap 5 is 1mm, which can enhance the integrity and stability of the entire reinforcement structure, improve the reinforcement effect on the cracks in the cap beam, and enhance the structural bearing capacity, durability, and waterproofness of the cap beam. Since the reserved width is only 1mm, the construction accuracy requirements are high. During construction, the reserved gap width can be increased. When tightening the bolts 31 later, the second mounting plate 21 and the first connecting plate 12 can be left untightened by adjusting the bolt length, but the difference in gap width before and after construction must be ensured to be 1mm. Alternatively, transverse prestress can be applied by controlling the tension of the bolts 31. The specific construction method should be comprehensively determined by the construction party based on the feasibility of the site.

[0050] In this embodiment, the first groove 111 and the second groove 211 can have triangular cross-sections, with the end furthest from the cap beam facing the gap 5; in other embodiments, the first groove 111 and the second groove 211 can also be semi-circular or other shapes. Both the adhesive and the bonding layer 41 can be made of structural Class A adhesive.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the reinforcement structure also includes a second connecting plate 22, a first rib 13, and a second rib 23. The first end of the second connecting plate 22 is connected to the top of the second mounting plate 21, and the two are perpendicular to each other. The second end of the second connecting plate 22 extends away from the first connecting plate 12, which increases the lateral stability of the structure and helps to distribute the stress. The adjacent sides of the first rib 13 are connected to the second side of the first mounting plate 11 and the first connecting plate 12, respectively, enhancing the connection strength between the first mounting plate 11 and the first connecting plate 12, improving the overall structural stability of both, and better able to withstand external loads. The adjacent sides of the second rib 23 are connected to the second side of the second mounting plate 21 and the second connecting plate 22, respectively, strengthening the connection between the second mounting plate 21 and the second connecting plate 22, further improving the stability of the entire reinforcement structure, effectively preventing relative displacement or deformation between components, thereby enhancing the reinforcement effect on the cap beam cracks. The reinforcement structure can be made entirely of steel plates. It is a right-angled component that can be fabricated in a factory and uses first-grade steel plates for welding. The welds are butt welds with bevel joints and the weld strength is equal to that of the base material.

[0052] The first mounting plate 11, the first connecting plate 12, the first rib 13, the second mounting plate 21, the second connecting plate 22, and the second rib 23 are all connected by ordinary bolts. During installation, the drilling of ordinary bolts should avoid the reinforcing steel bars of the cap beam. If necessary, the spacing can be adjusted appropriately, and the insertion depth of ordinary bolts should not be less than 10cm. In particular, when installing M12 bolts on the top and bottom surfaces of the cap beam, the hole diameter of the first mounting plate 11 should be appropriately increased to meet the requirements of tension displacement. The contact surface between the first rib 13 and the first mounting plate 11 is a critical section. When applying transverse prestress using fastening components, it is necessary to perform strength verification on the critical section of the tensioning end steel plate. At this time, the second rib 23 bears all the shear force of the reinforced structure, and the first connecting plate 12 bears all the bending moment of the reinforced structure.

[0053] like Figure 1 , Figure 5 and Figure 6 As shown, optionally, the reinforcement structure also includes a sleeve assembly. The sleeve assembly includes two sleeve pieces 61, which are respectively fitted over both ends of the gap 5. This prevents excessive overflow of the adhesive filling the gap 5, ensuring that the adhesive fully fills the gap 5 and effectively bonds the first connecting plate 12 and the second mounting plate 21. Simultaneously, the sleeve pieces 61 also protect the gap 5 and the internal adhesive, preventing damage or impact from external factors, thereby improving the overall stability and reinforcement effect of the cap beam crack reinforcement structure.

[0054] like Figure 1 , Figure 5 and Figure 6 As shown, optionally, the top of the first connecting plate 12 and the top of the second connecting plate 22 are flush. The sleeve 61 is a groove with an opening on one side, facing the gap 5. The top of the sleeve 61 is mounted on the upper side of the first connecting plate 12 and the second connecting plate 22. The first side 611 of the sleeve 61 is located on the side of the first connecting plate 12 away from the second mounting plate 21, and the second side 612 of the sleeve 61 is located on the side of the second mounting plate 21 away from the first connecting plate 12. This allows it to cover both ends of the gap 5, providing protection and preventing the adhesive in the gap 5 from being affected by external factors.

[0055] like Figure 1 , Figure 5 and Figure 6As shown, optionally, the first side 611 of the sleeve 61 is horizontally spaced from the first connecting plate 12, and the second side 612 of the sleeve 61 is horizontally spaced from the second mounting plate 21. This avoids direct contact between the sleeve 61 and the first connecting plate 12 and the second mounting plate 21, preventing damage to the first connecting plate 12 and the second mounting plate 21 during installation or use. Simultaneously, the horizontal spacing creates a buffer space, reducing the impact of external factors on the connection between the sleeve 61 and the first connecting plate 12 and the second mounting plate 21, improving the stability and durability of the overall structure, and facilitating future maintenance and repair of the sleeve 61, the first connecting plate 12, and the second mounting plate 21. Furthermore, the horizontal spacing facilitates the installation of the sleeve 61 while allowing adhesive to overflow and fill the first side 611 and the second side 612 during glue application, thereby achieving a reliable limiting effect through the solidified adhesive.

[0056] like Figure 1 , Figure 5 and Figure 6 As shown, optionally, the first side 611 of the sleeve 61 is provided with a first clearance portion 613, which snaps onto the first mounting plate 11, ensuring a reliable connection between the sleeve 61 and the first mounting plate 11, guaranteeing the stability of the sleeve 61 in this position, and reducing displacement of the sleeve 61 relative to the first mounting plate 11. The second side 612 of the sleeve 61 is provided with a second clearance portion 614, which snaps onto the second connecting plate 22, allowing the sleeve 61 to be firmly connected to the second connecting plate 22, reducing the risk of the sleeve 61 shaking or shifting relative to the second connecting plate 22. Overall, through the snapping action of the first clearance portion 613 and the second clearance portion 614, the sleeve 61 is accurately and stably placed over the end of the gap 5, providing better sealing when applying adhesive, preventing adhesive overflow, and improving the integrity and sealing of the reinforced structure. Both the first clearance portion 613 and the second clearance portion 614 are clearance through grooves.

[0057] like Figure 1 , Figure 5 and Figure 6 As shown, optionally, one bottom end of the sleeve 61 abuts against the first mounting plate 11 and the second mounting plate 21, ensuring the stability of the sleeve 61 in the installation position and reducing displacement of the sleeve 61; the other bottom end of the sleeve 61 extends away from the first mounting plate 11 and the second mounting plate 21, so that the sleeve 61 covers the end of the gap 5, effectively protecting the end of the gap 5 from external factors such as dust and moisture entering and reducing the adhesive performance. When applying adhesive, the adhesive can fill the upper bottom of the sleeve 61, further enhancing the sealing and connection strength between the sleeve 61 and the mounting plate, and the shape of the solidified adhesive achieves a limiting effect, improving the stability and reliability of the entire reinforcement structure, and better reinforcing the cracks in the cap beam.

[0058] Understandably, this reinforcement structure also includes necessary structures for connection, support, drive, positioning, limiting, sealing, and control functions to ensure its normal operation. The reinforcement structure can be entirely made of steel plates, and the shape, size, material, and quantity of each part can be determined as needed to achieve the corresponding functions. Considering the actual conditions of the cap beam, including the inability to attach steel plates to the decorative panels, support pads, and pier tops, and the fact that the cap beam defect is a transverse through crack, this reinforcement structure can be used in combination of two or more components. Ordinary bolts are used for four-sided steel reinforcement, and high-strength bolts are used to apply transverse prestress to the steel plates to achieve a clamping effect. Given that multiple combined forms already exist in existing technology, they will not be described in detail here. During installation, the cracks in the cap beam are first sealed and the original reinforcing steel plate is derusted and protected against corrosion. Then, the second mounting plate 21 is pasted and installed. After the second connecting plate 22 is installed and its edges are sealed with adhesive, the first mounting plate 11 and the first connecting plate 12 are fixed with ordinary bolts. Then, the tension is applied with bolts 31, and finally, the edges are sealed and poured.

[0059] The implementation principle of the cap beam crack reinforcement structure in this application embodiment is as follows: the first mounting plate 11 and the second mounting plate 21 are respectively used to connect to both sides of the cap beam. The first mounting plate 11 has several first grooves 111, which can increase the contact area with the adhesive layer 41, so that the adhesive layer 41 can adhere better and enhance the connection stability between the first mounting plate 11 and the first side of the cap beam. The first connecting plate 12 connects the first mounting plate 11 and is arranged parallel to and spaced apart from the second mounting plate 21, providing lateral support and connection for the entire reinforcement structure. The fastening component connects the first connecting plate 12 and the second mounting plate 21 and applies prestress to them, which can tighten the two, so that the reinforcement structure fits tightly to the cap beam, improves the reinforcement effect, prevents the crack from expanding further, and improves the load-bearing capacity, durability and waterproofness of the cap beam. At the same time, the cooperation between the adhesive layer 41 and the first grooves 111 can realize the limiting effect of the first mounting plate 11, reduce the risk of crack expansion and improve the reliability of reinforcement.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
