Description

Technical Field

[0001] This application belongs to the field of building and bridge technology, and more specifically, relates to a double-layer corrugated steel anti-collision energy dissipation reinforcement device. Background Technology

[0002] Bridge piers, as the main components of bridges, play a crucial role in the overall seismic performance of bridges. Numerous earthquake damages demonstrate that bridge collapses are primarily caused by insufficient seismic resistance of bridge piers. Currently, most bridge piers use internal energy-dissipating steel reinforcement for energy absorption and seismic protection, but this cannot be replaced once damaged. Even with the development of some external energy-dissipating devices, energy is primarily dissipated through friction, resulting in limited energy dissipation capacity, susceptibility to damage, and difficulty in replacement. Furthermore, given the post-earthquake repairability of bridge components based on resilience design, how to quickly repair plastic hinge zones and enhance their energy dissipation capacity and other seismic performance aspects has become a hot topic. In addition, major bridge collisions are inevitable, and the impact resistance of bridge piers is a vital part of bridge protection measures, making pier impact protection measures essential. Therefore, providing a bridge pier external double-layer corrugated steel impact-absorbing energy-dissipating reinforcement device with strong energy dissipation and impact resistance, and which can be quickly repaired and easily reinforced, is one of the urgent technical problems to be solved in this field.

The connector is installed between the deformation gaps, and its ends are fixedly connected to the inner corrugated plate and the outer corrugated plate, respectively.

[0005] In one possible implementation, the lower end of the outer corrugated plate is provided with a mounting plate arranged in a ring, the mounting plate having a plurality of connection holes and a plurality of fasteners for fixed connection with the foundation.

[0006] In one possible implementation, the plurality of connecting holes are arranged in a ring and uniformly, and the fastener is a bolt.

[0008] In one possible implementation, each end of the first arc-shaped corrugated steel sheet is provided with a plurality of first mounting holes, and the first mounting holes at the ends of two connected first arc-shaped corrugated steel sheets are coaxially aligned; each end of the second arc-shaped corrugated steel sheet is provided with a plurality of second mounting holes, and the second mounting holes at the ends of two connected second arc-shaped corrugated steel sheets are coaxially aligned; the two ends of the connector pass through two first mounting holes and two second mounting holes respectively and are fixedly connected to the two first arc-shaped corrugated steel sheets and the two second arc-shaped corrugated steel sheets.

[0009] In one possible implementation, the connector includes a double-ended bolt and four nuts, with the four nuts arranged in pairs and installed at both ends of the double-ended bolt. The double-ended bolt passes through two first mounting holes and two second mounting holes, and the two nuts in the same group are located on either side of the outer corrugated plate or on either side of the inner corrugated plate.

[0012] In one possible implementation, the corrugations of the inner corrugated plate extend vertically, and the corrugations of the outer corrugated plate extend laterally.

[0013] The beneficial effects of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application are as follows: Compared with the prior art, the double-layer corrugated steel anti-collision energy dissipation reinforcement device of this application, during installation, prefabricates inner and outer corrugated plates with corresponding curvature and length according to the diameter, height and design load of the bridge pier, and prefabricates suitable connectors at the same time; clean the installation area around the bridge pier (remove impurities and grind flat), splice the inner corrugated plates around the bridge pier, and there is a certain distance between the inner corrugated plates and the bridge pier, check the splicing and connection points to ensure that there is no looseness; then install the outer corrugated plates, which are fitted onto the outside of the inner corrugated plates, and adjust the spacing to form a deformation gap, and then fasten the lower end of the outer corrugated plates to the foundation; finally, install the connectors within the deformation gap, and fix them together with the inner and outer corrugated plates through the two ends of the connectors.

At the same time, this structure is placed outside the bridge pier, and the damaged inner corrugated plate, outer corrugated plate or connectors can be easily replaced after an earthquake or impact without damaging the bridge pier, which greatly shortens the repair time.

[0021] Please see Figures 1 to 4This application describes a double-layer corrugated steel anti-collision energy-dissipating reinforcement device. The device includes an inner corrugated plate 10, an outer corrugated plate 20, and a connector 30. The inner corrugated plate 10 is installed on the outside of a bridge pier 40 and arranged around it. The inner corrugated plate 10 is connected to the bridge pier 40, and the corrugations of the inner corrugated plate 10 extend vertically or horizontally. The outer corrugated plate 20 is installed on the outside of the inner corrugated plate 10 and arranged around it. The lower end of the outer corrugated plate 20 is fixedly connected to the foundation. The corrugation extension direction of the outer corrugated plate 20 is perpendicular to the corrugation extension direction of the inner corrugated plate 10. A deformation gap 21 exists between the outer corrugated plate 20 and the inner corrugated plate 10. The connector 30 is installed between the deformation gaps 21, and its ends are fixedly connected to the inner corrugated plate 10 and the outer corrugated plate 20, respectively.

[0022] The double-layer corrugated steel anti-collision energy-dissipating reinforcement device provided in this application, compared with the prior art, forms an integrated reinforcement device through an inner corrugated plate 10, an outer corrugated plate 20, and a connector 30. In this device, the inner corrugated plate 10 is arranged around the outer periphery of the pier 40 and connected to the pier 40, with its corrugations extending vertically or horizontally. The corrugated structure generates controllable deformation to dissipate energy during an earthquake. The outer corrugated plate 20 is fitted over the inner layer, with its lower end rigidly connected to the bridge foundation, and the direction of its corrugations is perpendicular to that of the inner corrugated plate 10. This perpendicular design allows the two layers to... The energy dissipation is achieved by deforming under loads in different directions, avoiding the limitations of energy dissipation in a single direction. At the same time, the outer corrugated plate 20 serves as the first line of defense against impacts, which can preferentially resist impacts to protect the pier 40 and the inner corrugated plate 10. The deformation gap 21 between the two plates provides space for deformation under stress, preventing the inner corrugated plate 10 and the outer corrugated plate 20 from being damaged prematurely due to insufficient space. The connector 30 is installed within the deformation gap 21 and fixes the inner corrugated plate 10 and the outer corrugated plate 20, which not only achieves uniform force transmission, but also assists in energy dissipation through its own deformation, forming a multi-layer energy dissipation system.

[0023] During installation, based on the diameter, height, and design load of the pier 40, prefabricate inner corrugated plates 10 and outer corrugated plates 20 with corresponding curvature and length, and simultaneously prefabricate suitable connectors 30. Clean the installation area around the pier 40 (remove impurities and grind smooth), and arrange the inner corrugated plates 10 around the pier 40, with a certain distance between the inner corrugated plates 10 and the pier 40. Check the splicing points and connection points to ensure there is no looseness. Then install the outer corrugated plates 20, which are fitted onto the outside of the inner corrugated plates 10. Adjust the spacing to form a deformation spacing 21, and then firmly connect the lower end of the outer corrugated plates 20 to the foundation. Finally, install the connectors 30 within the deformation spacing 21, and fix them together with the inner corrugated plates 10 and outer corrugated plates 20 through both ends of the connectors 30. After completion, check the overall structural stability to ensure there is no displacement or connection defects. In this way, the energy consumption capacity of the device is improved. The double-layered vertically arranged inner corrugated plate 10, outer corrugated plate 20 and connector 30 form a multi-path energy consumption, and the corrugated structure has strong fatigue resistance and outstanding anti-collision performance. At the same time, this structure is placed outside the pier 40, and the damaged inner corrugated plate 10, outer corrugated plate 20 or connector 30 can be easily replaced after an earthquake or impact without damaging the pier 40, and the repair time is greatly shortened.

[0024] A foundation 41 is set on the ground, the lower end of the pier 40 is supported on the foundation 41, and the lower end of the outer corrugated plate 20 is fixedly connected to the foundation 41.

[0025] Please see Figures 1 to 4 As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, the lower end of the outer corrugated plate 20 is provided with a ring-shaped mounting plate 22. The mounting plate 22 is provided with multiple connecting holes 23 and multiple fasteners 24 for fixed connection with the foundation. The ring-shaped mounting plate 22 at the lower end of the outer corrugated plate 20 is precisely adapted to the surrounding shape of the outer corrugated plate 20, and can conform to the top surface of the foundation to form a continuous ring-shaped force-bearing surface. The multiple connecting holes 23 on the mounting plate 22 are evenly distributed to correspond to the fasteners 24 (such as high-strength bolts), ensuring accurate alignment and balanced fixing points during installation. In this way, the ring structure can avoid local stress concentration, and the combination of connecting holes 23 and fasteners 24 realizes a detachable rigid connection without relying on irreversible fixing methods such as welding. The coaxiality of the outer corrugated plate 20 is easy to adjust during installation, and the shear resistance is strong after fixing. It can smoothly transfer the impact force and seismic force borne by the outer layer to the foundation, avoiding displacement or overturning of the outer layer.

[0026] Please see Figures 1 to 4As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, multiple connecting holes 23 are arranged uniformly in a ring, and bolts are used as fasteners 24; multiple connecting holes 23 are evenly distributed in a ring along the mounting plate 22, and bolts are used as fasteners 24. The uniform arrangement of connecting holes 23 can ensure that the bolts are subjected to completely consistent force, avoiding deformation or breakage of the mounting plate 22 caused by local stress concentration; the bolts are general-purpose fasteners 24, which can be operated without special construction tools.

[0027] Please see Figures 2 to 4 As a specific embodiment of the double-layer corrugated steel anti-collision energy-dissipating reinforcement device provided in this application, the outer corrugated plate 20 has a plurality of first arc-shaped corrugated steel plates 25 connected in sequence and arranged in a ring, and the inner corrugated plate 10 has a plurality of second arc-shaped corrugated steel plates 11 connected in sequence and arranged in a ring, and the lower ends of the plurality of first arc-shaped corrugated steel plates 25 are all fixedly connected to the foundation; the number of connectors 30 is plurality of, and they are arranged in multiple groups; the connection positions of the plurality of first arc-shaped corrugated steel plates 25 and the plurality of second arc-shaped corrugated steel plates 11 are... The corrugated steel sheets 11 are connected one-to-one, and the connectors 30 are fixedly connected to the corresponding first arc-shaped corrugated steel sheets 25 and second arc-shaped corrugated steel sheets 11. The inner corrugated plate 10 and the outer corrugated plate 20 are respectively divided into multiple second arc-shaped corrugated steel sheets 11 and multiple first arc-shaped corrugated steel sheets 25, which are spliced ​​into a ring. The lower ends of the first arc-shaped corrugated steel sheets 25 are all fixed to the foundation, and the connection positions of the inner and outer steel sheets are one-to-one. The connectors 30 are fixed in multiple groups at these connection positions. The modular splicing design breaks through the size limitations of the integral corrugated plate and adapts to piers 40 of different diameters. The alignment of the connection positions and the design of the grouped connectors 30 make the force transmission more precise and avoid local stress concentration caused by connection misalignment. The connectors 30 are arranged in corresponding connection positions, which can simultaneously reinforce the splicing seam and improve the overall rigidity of the inner corrugated plate 10 and the outer corrugated plate 20.

[0028] Please see Figures 2 to 4As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, both ends of the first arc-shaped corrugated steel plate 25 are provided with a plurality of first mounting holes 26, and the first mounting holes 26 at the ends of two connected first arc-shaped corrugated steel plates 25 are coaxially aligned; both ends of the second arc-shaped corrugated steel plate 11 are provided with a plurality of second mounting holes 12, and the second mounting holes 12 at the ends of two connected second arc-shaped corrugated steel plates 11 are coaxially aligned; both ends of the connector 30 pass through two first mounting holes 26 and two second mounting holes 12 respectively and are connected to the two first arc-shaped corrugated steel plates 25 and the two second arc-shaped corrugated steel plates 25. The first arc-shaped corrugated steel plate 25 has several first mounting holes 26 at both ends, and the first mounting holes 26 at the ends of adjacent plates are coaxially aligned. The second arc-shaped corrugated steel plate 11 has several second mounting holes 12 at both ends, and the second mounting holes 12 at the ends of adjacent plates are also coaxially aligned. Through the coaxially aligned first mounting holes 26 or second mounting holes 12 and the through-hole connector 30, the plates are spliced ​​and connected to the inner corrugated plate 10 and the outer corrugated plate 20 as a whole. This completes the ring splicing of adjacent arc-shaped corrugated steel plates and achieves the coordinated fixation of the inner corrugated plate 10 and the outer corrugated plate 20, simplifying the connection structure. The connector 30 simultaneously bears the splicing fastening force of the plates and the connection force of the inner corrugated plate 10 and the outer corrugated plate 20, improving the overall structural stability and eliminating the need for additional splicing fasteners, thus reducing the number of components.

[0029] Please see Figure 1 and Figure 4 As a specific embodiment of the double-layer corrugated steel anti-collision energy-dissipating reinforcement device provided in this application, the connector 30 includes a double-ended bolt 31 and four nuts 32. The four nuts 32 are arranged in pairs and installed at both ends of the double-ended bolt 31. The double-ended bolt 31 passes through two first mounting holes 26 and two second mounting holes 12. The two nuts 32 in the same group are located on both sides of the outer corrugated plate 20 or both sides of the inner corrugated plate 10. Standardized fasteners 24 are used, eliminating the need for customized parts. Bidirectional fixation is achieved by clamping with nuts 32 on both sides, avoiding the problem of easy loosening with unilateral fixation. This connection method does not require welding during installation; fixation can be completed simply by tightening the nuts 32. The spacing between the inner and outer corrugated plates 20 can also be adjusted by finely adjusting the tightness of the nuts 32 to ensure that the deformation space meets the design requirements. During disassembly, only the nuts 32 need to be removed, making it easy to replace damaged plates or connectors 30 individually. The clamping on both sides can effectively resist the loosening force generated by vibration and impact.

[0030] Please see Figures 1 to 4As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, there are multiple first mounting holes 26, which are evenly spaced vertically; there are multiple second mounting holes 12, which are also evenly spaced vertically. The distribution of mounting holes precisely matches the vertical dimensions of the corrugated plate, and the spacing between the upper and lower holes is consistent, forming a vertically uniform stress node, and is height-adapted to the vertical arrangement requirements of the connector 30. This method allows for flexible selection of mounting holes at corresponding vertical positions to assemble the connector 30 according to the height of the pier 40 and the load requirements, avoiding stress concentration caused by a single hole position; at the same time, the vertical uniform distribution ensures that the inner corrugated plate 10 and the outer corrugated plate 20 are subjected to balanced forces, preventing premature damage due to local overload.

[0031] Please see Figures 1 to 4 As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, the first arc-shaped corrugated steel plate 25 and the second arc-shaped corrugated steel plate 11 are both designed as two semi-circular structures. After splicing, they form a complete ring-shaped outer and inner corrugated plate 10, which precisely fits the circular cross-section bridge pier 40. The semi-circular structure has high symmetry, and only two interfaces need to be connected during splicing, eliminating the need for sequential splicing of multiple plates and simplifying the structural composition. The semi-circular plates have moderate volume and weight, facilitating factory prefabrication, transportation, and on-site hoisting, reducing reliance on large equipment; fewer splicing interfaces can reduce installation alignment errors and improve the coaxiality of the ring structure.

[0032] Please see Figures 1 to 4 As a specific embodiment of the double-layer corrugated steel anti-collision energy dissipation reinforcement device provided in this application, the corrugations of the inner corrugated plate 10 extend vertically, and the corrugations of the outer corrugated plate 20 extend horizontally, forming a double-layer structure with vertical corrugation directions. The vertical corrugations in the inner corrugated plate 10 can effectively resist horizontal seismic forces (the corrugations easily bend and deform along the horizontal direction to dissipate energy), while the horizontal corrugations in the outer corrugated plate 20 can better buffer lateral impact forces (the corrugations deform and absorb energy along the impact direction), achieving complementary load responses. This vertical corrugation direction breaks the limitation of energy dissipation in a single direction, allowing the device to stably dissipate energy under various load scenarios such as horizontal earthquakes and lateral impacts, and the deformation of the inner and outer layers does not interfere with each other and works synergistically.

[0033] Please see Figure 1A pre-casting gap 13 is reserved between the inner corrugated plate 10 and the pier 40, and multiple studs 14 are placed within the gap on the inner wall of the inner corrugated plate 10 as reinforcements. After the concrete is poured into the gap, the studs and concrete form a stable connection, creating a composite connection structure. This avoids direct hard contact between the inner corrugated plate 10 and the pier 40, while achieving a firm bond through concrete filling. The studs enhance the interlocking strength with the concrete. The casting gap 13 can accommodate uneven surfaces of the pier 40, and the leveling with concrete ensures the fit of the inner corrugated plate 10. The reinforcements 14 effectively prevent the inner corrugated plate 10 from peeling off from the concrete, improving the connection's pull-out and shear resistance.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
