Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge engineering, and particularly to an arch bridge hanger anchoring structure with a flexible adjustment function. Background Art
[0002] In the field of bridge engineering, especially for mid - supported and through - arch bridge structures, hangers, as the core load - bearing components connecting the bridge deck and the arch ring, the rationality and stability of their design are directly related to the safety performance and service life of the entire bridge. The main responsibility of the hanger is to efficiently transfer various loads borne by the bridge deck to the underlying piers and abutments, thereby maintaining the overall mechanical balance and structural stability of the bridge. However, under the existing technical conditions, the anchoring design between the hanger and the arch ring lacks the necessary automatic leveling function when dealing with dynamic loads (such as the impact effect when vehicles pass quickly, strong wind loads, and potential seismic activities, etc.).
[0003] Traditional anchoring designs, such as steel anchor box connections, although showing high efficiency and convenience in the initial stage of construction, gradually reveal their limitations during long - term operation. Although the steel anchor box connection provides strong rigid support, under extreme dynamic loads, the rigid connection points often become high - risk areas of stress concentration, accelerating the fatigue damage of materials and even potentially leading to the loosening or failure of the anchoring system.
[0004] More critically, the currently widely used anchoring cushion designs are often composed of rigid materials or simple filling structures, lacking sufficient flexibility and adaptability to respond to the small offsets of the hanger caused by the overall deformation of the bridge or external disturbances. Under the action of dynamic loads, once the hanger deflects, the traditional rigid cushion cannot automatically adjust its position or shape to disperse stress, resulting in the accumulation of displacement deviation and the aggravation of stress concentration. This not only limits the self - adjustment ability of the hanger in a complex load environment but also seriously weakens the seismic resistance, wind resistance, and durability of the entire bridge. Summary of the Invention
[0005] The purpose of the present invention is to provide an arch bridge hanger anchoring structure with a flexible adjustment function to solve the problem that the existing anchoring design between the hanger and the arch ring lacks an automatic leveling function.
[0006] To achieve the above - mentioned purpose, the technical solution adopted by the present invention is as follows:
[0007] An arch bridge hanger anchoring structure with a flexible adjustment function, comprising: a hanger, a first anchor plate and an arch ring, wherein the first anchor plate is located on the side of the arch ring away from the bridge deck; the hanger is anchored on the first anchor plate and passes through the arch ring to be connected with the bridge deck; a plurality of reinforcement members, each of the reinforcement members is anchored on the first anchor plate, passes through the arch ring and is connected with the hanger, and the plurality of reinforcement members are evenly distributed around the hanger to disperse the stress of the hanger; a plurality of flexible leveling components, each of the flexible leveling components is sleeved on each of the reinforcement members, and each of the flexible leveling components is located between the first anchor plate and the arch ring; each of the flexible leveling components is configured to be able to expand and contract to flexibly adjust the tension of the hanger.
[0008] According to the above technical means, by introducing a plurality of flexible leveling components, the present invention can not only automatically respond to the small deformations of the bridge caused by environmental factors (such as temperature changes, foundation settlement) or external loads, but also realize the flexible adjustment of the hanger tension under the action of dynamic loads such as vehicle impact, strong wind or earthquake. Since the flexible leveling components can expand and contract according to the displacement requirements of the hanger, effectively absorbing and dispersing the stress fluctuations caused by dynamic loads, thereby protecting the hanger and the arch ring from instantaneous high-stress impacts, and significantly improving the overall stability and durability of the bridge structure.
[0009] In the present invention, a plurality of reinforcement members are evenly distributed around the hanger, which not only enhances the connection strength between the hanger and the arch ring, but also effectively disperses the load stress borne by the hanger through the synergistic effect. Combined with the adjustment function of the flexible leveling components, it further ensures that the stress is evenly distributed in a wider area, avoids the occurrence of stress concentration, and prolongs the service life of the hanger and the entire anchoring system.
[0010] Further, each of the flexible leveling components includes a first elastic member and a second elastic member, the first elastic member is sleeved on the reinforcement member, and the second elastic member is sleeved on the first elastic member.
[0011] According to the above technical means, the superimposed use of the first elastic member and the second elastic member significantly enhances the elastic adjustment range and adaptability of the flexible leveling components, enabling the flexible leveling components to better absorb and disperse the stress fluctuations caused by dynamic loads, and further improving the stability and durability of the connection between the hanger and the arch ring.
[0012] Through the synergistic effect of the double-layer elastic members, the flexible leveling assembly can more effectively disperse the stress borne by the suspender to the surrounding reinforcement members and arch rings, which helps to reduce the stress concentration phenomenon and lower the risk of damage to the suspender and anchoring system due to long-term high stress. At the same time, the different elastic characteristics of the first elastic member and the second elastic member can complement each other, enabling the flexible leveling assembly to more precisely adjust its telescopic amount when dealing with displacement changes of different magnitudes and directions, thereby achieving rapid and accurate automatic adjustment of the suspender tension.
[0013] Furthermore, the first elastic member is a rubber sleeve; the second elastic member is a wire spring.
[0014] According to the above technical means, the rubber sleeve (the first elastic member) can effectively absorb and disperse the stress fluctuations caused by dynamic loads with its good elasticity and resilience. The wire spring (the second elastic member) further enhances the overall elastic adjustment range and recovery performance of the flexible leveling assembly with its high elasticity and load-bearing capacity, ensuring the stability of the connection between the suspender and the arch ring. The combined use of the rubber sleeve and the wire spring enables the flexible leveling assembly to better disperse the stress borne by the suspender to the surrounding structure, reducing the stress concentration phenomenon. At the same time, the wear resistance and anti-aging performance of the rubber material, as well as the high durability and anti-fatigue performance of the wire spring, jointly improve the service life and safety of the anchoring system.
[0015] At the same time, due to the elastic deformation characteristics of the rubber sleeve, it can quickly respond to the small displacement changes of the suspender, while the linear elastic characteristics of the wire spring ensure the accuracy and stability of the adjustment, enabling the flexible leveling assembly to more flexibly adjust its telescopic amount when dealing with loads of different magnitudes and directions, and achieving precise automatic adjustment of the suspender tension.
[0016] Furthermore, it further includes fasteners, and each of the reinforcement members is connected to the suspender through the fasteners.
[0017] According to the above technical means, the use of the fasteners ensures the firm connection between the reinforcement members and the suspender, ensuring the displacement synchronism between the reinforcement members and the suspender, enabling the flexible leveling assembly to more accurately sense the displacement changes of the suspender when dealing with dynamic loads and quickly make adjustments, achieving precise automatic control of the suspender tension.
[0018] Further, each of the reinforcement members is a steel strand; a first through-hole and a plurality of second through-holes are formed on the fastener. The first through-hole penetrates along the axial direction of the fastener. Each of the second through-holes is uniformly distributed on the side wall of the fastener, and each of the second through-holes communicates with the first through-hole; each of the steel strands can pass through each of the second through-holes and extend into the first through-hole; the first through-hole is adapted to the suspender, and the suspender can pass through the first through-hole and be connected to the bridge deck; when the suspender passes through the first through-hole, the suspender can tension each of the steel strands in the first through-hole along the axial direction of the fastener, so that each of the steel strands is fixedly connected to the suspender.
[0019] According to the above technical means, in the connection structure of the suspender and the steel strand, the suspender is the wedge block. When the suspender penetrates the first through-hole, it can use its wedging principle to tightly lock the steel strand on the fastener, effectively preventing the steel strand from loosening or falling off during long-term use, and enhancing the connection strength and stability of the entire anchoring structure.
[0020] At the same time, during the process of the suspender penetrating the first through-hole and tensioning the steel strand, the stress borne by the suspender can be effectively transmitted to the surrounding steel strands, which helps to optimize the stress transmission path, reduce the stress concentration phenomenon, and improve the durability and safety of the anchoring structure.
[0021] Further, a plurality of grooves are formed around the side wall of the fastener. At least two adjacent grooves intersect with each other, and each of the grooves is adapted to each of the steel strands, so that each of the steel strands can be cross-wound around the side wall of the fastener along the grooves; each of the grooves communicates with each of the second through-holes, so that after each of the steel strands is cross-wound along the grooves, it can pass through each of the second through-holes and extend into the first through-hole.
[0022] According to the above technical means, by designing the intersecting grooves, the steel strands can be tightly and cross-wound around the side wall of the fastener along these grooves, which not only increases the contact area between the steel strands and the fastener, but also improves the stability and reliability of the connection by the cross-winding method, effectively preventing the steel strands from loosening or falling off.
[0023] Further, a first anchor is further included. A first anchor hole is formed on the first anchor plate. The first anchor is installed on the suspender, and the first anchor is adapted to the first anchor hole, so that the suspender can be anchored on the first anchor plate.
[0024] According to the above technical means, through the adaptation of the first anchor and the first anchor hole, the suspender can be firmly anchored on the first anchor plate, enhancing the overall stability of the anchoring structure, so that the suspender can remain stable when bearing external loads and is not prone to displacement or falling off.
[0025] Further, it further includes a plurality of second anchor members. A plurality of second anchor holes are formed on the first anchor plate. Each of the second anchor members is installed on each of the reinforcement members, and each of the second anchor members is adapted to each of the second anchor holes, so that each of the reinforcement members is anchored on the first anchor plate.
[0026] According to the above technical means, each reinforcement member is anchored by an independent second anchor member. This multi-point anchoring method enhances the reliability of the anchoring, and at the same time enhances the stability of the overall structure, and improves the bearing capacity of the bridge or other structures.
[0027] Further, it further includes a second anchor plate. The second anchor plate abuts against the side of the arch ring away from the bridge deck, and the second anchor plate is located between the flexible leveling assembly and the arch ring; the suspender sequentially passes through the first anchor plate, the second anchor plate and the arch ring and is connected to the bridge deck; each of the reinforcement members sequentially passes through the first anchor plate, the second anchor plate and the arch ring and is connected to the suspender.
[0028] According to the above technical means, the addition of the second anchor plate forms an additional support layer, enhances the connection between the arch ring and the bridge deck, thereby improving the integrity and stability of the entire anchoring structure, contributing to resisting external loads and vibrations, and ensuring the safe operation of the suspender.
[0029] Further, it further includes a rigid support member. The rigid support member is sleeved on the suspender, and the rigid support member is located between the first anchor plate and the second anchor plate.
[0030] According to the above technical means, the rigid support member provides additional support for the suspender, enhances the stability of the suspender when bearing loads, helps to reduce the bending and vibration of the suspender, and improves the overall stiffness and bearing capacity of the bridge.
[0031] The beneficial effects achieved by the present invention:
[0032] By introducing a plurality of flexible leveling assemblies, the present invention can not only automatically respond to the minute deformations of the bridge caused by environmental factors (such as temperature changes, foundation settlement) or external loads, but also achieve flexible adjustment of the suspender tension under dynamic loads such as vehicle impact, strong wind or earthquake. Since the flexible leveling assembly can be telescopically adjusted according to the displacement requirements of the suspender, it effectively absorbs and disperses the stress fluctuations caused by dynamic loads, thereby protecting the suspender and the arch ring from instantaneous high-stress impacts, and significantly improving the overall stability and durability of the bridge structure.
[0033] The present invention evenly distributes a plurality of reinforcing members around the suspender, which not only enhances the connection strength between the suspender and the arch ring, but also effectively disperses the load stress borne by the suspender through synergistic action. Combining with the adjustment function of the flexible leveling component, it further ensures the uniform distribution of stress in a wider area, avoids the occurrence of stress concentration phenomenon, and prolongs the service life of the suspender and the entire anchoring system.

[0058] The following will introduce and describe the technical solutions of this embodiment in detail with reference to the specific accompanying drawings.
[0059] Such as Figure 1As shown, this embodiment proposes an arch bridge hanger anchoring structure with a flexible adjustment function, including: hanger 1, first anchor plate 2 and arch ring 3. As Figure 1 and Figure 3 shown, the first anchor plate 2 is located on the side of the arch ring 3 away from the bridge deck; the hanger 1 is anchored on the first anchor plate 2 and passes through the arch ring 3 to be connected to the bridge deck; a plurality of reinforcing members 4, each reinforcing member 4 is anchored on the first anchor plate 2, passes through the arch ring 3 and is connected to the hanger 1, and the plurality of reinforcing members 4 are evenly distributed around the hanger 1 to disperse the stress of the hanger 1; a plurality of flexible leveling components 5, each flexible leveling component 5 is sleeved on each reinforcing member 4, and each flexible leveling component 5 is located between the first anchor plate 2 and the arch ring 3; each flexible leveling component 5 is configured to be able to expand and contract to flexibly adjust the tension of the hanger 1.
[0060] The specific adjustment working process is as follows:
[0061] During the bridge construction stage, the hanger 1 is accurately anchored on the first anchor plate 2 and passes through the arch ring 3 to be firmly connected to the bridge deck. A plurality of reinforcing members 4 are evenly distributed around the hanger 1 and are also anchored on the first anchor plate 2, passing through the arch ring 3 to form a stable connection network with the hanger 1 to disperse the stress borne by the hanger 1. The flexible leveling components 5 are sleeved on each reinforcing member 4 and are located between the first anchor plate 2 and the arch ring 3. These components maintain a certain pre-tightening force in the initial state to ensure that they can quickly respond to subsequent displacement changes.
[0062] When the bridge is subjected to dynamic loads (such as vehicle impact, strong wind or earthquake), the hanger 1 and the surrounding reinforcing members 4 will experience small displacements and stress changes. The flexible leveling component 5 can sense and respond to the displacement changes of the hanger 1 and the reinforcing members 4 inside. According to the direction and magnitude of the displacement, the flexible leveling component 5 will expand and contract accordingly to absorb and disperse the stress fluctuations caused by the dynamic loads, and perform automatic and continuous adjustments to ensure that the connection between the hanger 1 and the reinforcing members 4 always remains stable.
[0063] Under the adjustment of the flexible leveling component 5, the stress borne by the hanger 1 is more evenly dispersed to the surrounding reinforcing members 4, which helps to reduce the occurrence of stress concentration phenomena, thereby extending the service life of the hanger and the entire anchoring system. At the same time, the adjustment of the flexible leveling component 5 also ensures that the connection between the hanger 1 and the bridge deck maintains a certain degree of tension, preventing the risk of structural damage caused by displacement deviation.
[0064] In this embodiment, by introducing multiple flexible leveling components 5, the present invention can not only automatically respond to the minor deformations of the bridge caused by environmental factors (such as temperature changes, foundation settlement) or external loads, but also achieve flexible adjustment of the tension of the suspender 1 under the action of dynamic loads such as vehicle impact, strong wind or earthquake. Since the flexible leveling component 5 can be telescopically adjusted according to the displacement requirements of the suspender 1, it effectively absorbs and disperses the stress fluctuations caused by dynamic loads, thereby protecting the suspender 1 and the arch ring 3 from instantaneous high-stress impacts, and significantly improving the overall stability and durability of the bridge structure.
[0065] In this embodiment, a plurality of reinforcing members 4 are evenly distributed around the suspender 1, which not only enhances the connection strength between the suspender 1 and the arch ring 3, but also effectively disperses the load stress borne by the suspender 1 through synergistic action. Combining with the adjustment function of the flexible leveling component, it further ensures that the stress is evenly distributed in a wider area, avoids the occurrence of stress concentration, and prolongs the service life of the suspender 1 and the entire anchoring system.
[0066] As Figure 4 shown, each flexible leveling component 5 includes a first elastic member 51 and a second elastic member 52. The first elastic member 51 is sleeved on the reinforcing member 4, and the second elastic member 52 is sleeved on the first elastic member 51.
[0067] The superimposed use of the first elastic member 51 and the second elastic member 52 significantly enhances the elastic adjustment range and adaptability of the flexible leveling component 5, enabling the flexible leveling component 5 to better absorb and disperse the stress fluctuations caused by dynamic loads, and further improving the stability and durability of the connection between the suspender 1 and the arch ring 3.
[0068] Through the synergistic action of the double-layer elastic members, the flexible leveling component 5 can more effectively disperse the stress borne by the suspender 1 to the surrounding reinforcing members 4 and the arch ring 3, which helps to reduce the stress concentration phenomenon and reduce the risk of damage to the suspender and the anchoring system due to long-term high-stress action. At the same time, the different elastic characteristics of the first elastic member 51 and the second elastic member 52 can complement each other, enabling the flexible leveling component 5 to more precisely adjust its telescopic amount when dealing with displacement changes of different sizes and directions, thereby realizing rapid and accurate automatic adjustment of the tension of the suspender 1.
[0069] In this embodiment, the first elastic member 51 is a rubber sleeve; the second elastic member 52 is a wire spring.
[0070] The rubber sleeve (the first elastic member 51), with its good elasticity and resilience, can effectively absorb and disperse the stress fluctuations caused by dynamic loads. The steel wire spring (the second elastic member 52), with its high elasticity and load-bearing capacity, further enhances the overall elastic adjustment range and recovery performance of the flexible leveling assembly 5, ensuring the stability of the connection between the suspender 1 and the arch ring 3. The combined use of the rubber sleeve and the steel wire spring enables the flexible leveling assembly 5 to better disperse the stress borne by the suspender 1 into the surrounding structure, reducing the stress concentration phenomenon. At the same time, the wear-resistant and anti-aging properties of the rubber material, as well as the high durability and anti-fatigue properties of the steel wire spring, jointly improve the service life and safety of the anchoring system.
[0071] At the same time, due to the elastic deformation characteristics of the rubber sleeve, it can quickly respond to the small displacement changes of the suspender, while the linear elastic characteristics of the steel wire spring ensure the accuracy and stability of the adjustment. When the flexible leveling assembly 5 is dealing with loads of different magnitudes and directions, it can more flexibly adjust its telescopic amount to achieve precise automatic adjustment of the suspender tension.
[0072] As Figure 1 shown, it also includes fasteners 6, and each reinforcing member 4 is connected to the suspender 1 through the fasteners 6.
[0073] The use of the fasteners 6 ensures the firm connection between the reinforcing member 4 and the suspender 1, ensuring the displacement synchronism between the reinforcing member 4 and the suspender 1. When the flexible leveling assembly 5 is dealing with dynamic loads, it can more accurately sense the displacement changes of the suspender 1 and quickly make adjustments to achieve precise automatic control of the suspender 1 tension.
[0074] As Figure 1 shown, each reinforcing member 4 is a steel strand; as Figures 5 - 7 shown, the fastener 6 is formed with a first through-hole 61 and a plurality of second through-holes 62. The first through-hole 61 penetrates along the axial direction of the fastener 6, and each second through-hole 62 is evenly distributed on the side wall of the fastener 6, and each second through-hole 62 is communicated with the first through-hole 61; each steel strand can pass through each second through-hole 62 and extend into the first through-hole 61; the first through-hole 61 is adapted to the suspender 1, and the suspender 1 can pass through the first through-hole 61 and be connected to the bridge deck; when the suspender 1 passes through the first through-hole 61, the suspender 1 can tighten each steel strand in the first through-hole 61 along the axial direction of the fastener 6, so that each steel strand is fixedly connected to the suspender 1.
[0075] In the connection structure between the suspender 1 and the steel strand, the suspender 1 is the wedge block. When the suspender 1 penetrates the first through-hole 61, it can use its wedging principle to tightly lock the steel strand on the fastener 6, effectively preventing the steel strand from loosening or falling off during long-term use, and enhancing the connection strength and stability of the entire anchoring structure.
[0076] Meanwhile, during the process of the suspender 1 passing through the first through-hole 61 and tensioning the steel strand, the stress borne by the suspender 1 can be effectively transmitted to the surrounding steel strands, which helps to optimize the stress transmission path, reduce the stress concentration phenomenon, and improve the durability and safety of the anchoring structure.
[0077] Preferably in this embodiment, the fastener 6 adopts a tapered wedge-type anchor structure. Through its tapered design and wedging principle, the tapered wedge-type anchor structure can generate a huge anchoring force to firmly lock the steel strand (reinforcement 4) on the suspender 1.
[0078] The installation process of the tapered wedge-type anchor structure is relatively simple. Only need to pass the steel strand through the second through-hole 62 on the fastener 6, and use the wedging action of the suspender 1 passing through the first through-hole 61 to fix the steel strand and the suspender 1.
[0079] As Figures 5 - 7 shown, a plurality of grooves 63 are formed around the side wall of the fastener 6. At least two adjacent grooves 63 intersect with each other, and each groove 63 is adapted to each steel strand, so that each steel strand can be wound around the side wall of the fastener 6 along the intersection of the grooves 63; each groove 63 is connected to each second through-hole 62, so that each steel strand can extend into the first through-hole 61 through each second through-hole 62 after being wound around the side wall of the fastener 6 along the intersection of the grooves 63.
[0080] In this embodiment, by designing the intersecting grooves 63, the steel strands can be tightly and cross-wound around the side wall of the fastener 6 along these grooves 63, which not only increases the contact area between the steel strands and the fastener 6, but also improves the stability and reliability of the connection by the cross-winding method, effectively preventing the loosening or falling off of the steel strands.
[0081] As Figures 5 - 7 shown, to further improve the connection firmness between the steel strand and the suspender 1, a toothed gap is formed on the side wall of the fastener 6 in this embodiment. The toothed gap extends along the axial direction of the fastener 6 and is connected to the first through-hole 61, so that the fastener 6 itself has a certain space for shrinkage deformation. When the suspender 1 passes through the first through-hole 61 and tensions the steel strand, since the steel strand is wound around the side wall of the fastener 6, the steel strand can tension the fastener 6, causing the toothed gap to shrink, thereby enhancing the connection strength between the fastener 6, the steel strand and the suspender 1, and realizing the stable connection between the steel strand and the suspender 1.
[0082] Preferably, as Figure 5As shown, four grooves 63 are formed on the side wall of the fastener 6, and two adjacent grooves 63 cross each other in an X shape, and each groove 63 is connected to each second through hole 62, so that two adjacent steel strands are cross-wound along two adjacent grooves 63 and then extend through each second through hole 62 to the first through hole 61. This cross-wound method not only increases the contact area between the steel strands and the fastener, but also improves the overall stability and strength of the structure through the X-shaped layout, helps to resist external loads and vibrations, and ensures the long-term safety and reliability of the anchoring structure.
[0083] In this embodiment, Figures 6 - 7 As shown, four grooves 63 are formed on the side wall of the fastener 6, and each groove 63 is spirally arranged around the side wall of the fastener 6, so that the four grooves 63 intersect with each other, thereby allowing the steel strands to be intertwined with each other along a specific path, forming a tight and stable connection.
[0084] like Figure 2 As shown, the arch bridge hanger anchoring structure also includes a first anchor 7, a first anchor hole 21 is formed on the first anchor plate 2, the first anchor 7 is installed on the hanger 1, and the first anchor 7 is adapted to the first anchor hole 21 so that the hanger 1 can be anchored on the first anchor plate 2.
[0085] By adapting the first anchor 7 to the first anchor hole 21, the hanger 1 can be firmly anchored on the first anchor plate 2, thereby enhancing the overall stability of the anchoring structure, so that the hanger 1 can remain stable when subjected to external loads and is not prone to displacement or falling off.
[0086] In this embodiment, the first anchor 7 preferably adopts a conical wedge structure. The conical wedge structure can generate a large friction force through the wedging effect after being inserted into the first anchor hole 21, thereby enhancing the anchoring force, so that the first anchor 7 can be more firmly fixed in the first anchor hole 21 and is not easy to loosen or fall off.
[0087] In this embodiment, preferably, Figure 1 and Figure 2 As shown, a tooth-shaped gap is formed on the first anchor 7, and the tooth-shaped gap extends axially along the first anchor 7. The design of the tooth-shaped gap allows a certain shrinkage space for the first anchor 7 when inserted into the first anchor hole 21. When the first anchor 7 is pushed into the first anchor hole 21 under pressure, the tooth-shaped gap part will shrink, thereby holding the boom 1 tightly, thereby increasing the connection stability and reliability of the first anchor 7 and the boom 1.
[0088] like Figure 1As shown, the arch bridge hanger anchoring structure further includes a plurality of second anchor members 8. A plurality of second anchor holes 22 are formed on the first anchor backing plate 2. Each second anchor member 8 is installed on each reinforcement member 4, and each second anchor member 8 is adapted to each second anchor hole 22, so that each reinforcement member 4 is anchored on the first anchor backing plate 2.
[0089] Each reinforcement member 4 is anchored by an independent second anchor member 8. This multi-point anchoring method enhances the reliability of the anchoring, and at the same time enhances the stability of the overall structure and improves the load-bearing capacity of the bridge or other structures.
[0090] Preferably in this embodiment, the second anchor member 8 adopts a conical wedge structure. The conical wedge structure can generate a large frictional force through the wedging action after being inserted into the second anchor hole 22, thereby enhancing the anchoring force, so that the second anchor member 8 can be more firmly fixed in the second anchor hole 22 and is not easy to loosen or fall off.
[0091] Preferably in this embodiment, a toothed gap is formed on the second anchor member 8. The toothed gap extends along the axial direction of the second anchor member 8. The design of the toothed gap allows the second anchor member 8 to have a certain contraction space when inserted into the second anchor hole 22. When the second anchor member 8 is pushed into the second anchor hole 22 under pressure, the toothed gap part will contract, thereby tightly holding the reinforcement member 4 and increasing the connection stability and reliability between the second anchor member 8 and the reinforcement member 4.
[0092] As Figure 1 shown, the arch bridge hanger anchoring structure further includes a second anchor backing plate 9. The second anchor backing plate 9 abuts against the side of the arch ring 3 away from the bridge deck, and the second anchor backing plate 9 is located between the flexible leveling assembly 5 and the arch ring 3; the hanger 1 sequentially passes through the first anchor backing plate 2, the second anchor backing plate 9 and the arch ring 3 and is connected to the bridge deck; each reinforcement member 4 sequentially passes through the first anchor backing plate 2, the second anchor backing plate 9 and the arch ring 3 and is connected to the hanger 1.
[0093] The addition of the second anchor backing plate 9 forms an additional support layer, enhancing the connection between the arch ring 3 and the bridge deck, thereby improving the integrity and stability of the entire anchoring structure, helping to resist external loads and vibrations, and ensuring the safe operation of the hanger 1.
[0094] As Figure 8 shown, it is easy to think that the second anchor backing plate 9 can adaptively adjust the radian of its contact surface according to the different radian positions of the arch ring 3 to ensure that the second anchor backing plate 9 abuts against the arch ring 3. The second anchor backing plate 9 with a radian adaptation can better disperse the stress on the arch ring 3, reduce the stress concentration phenomenon, and further reduce the risk of fatigue damage of the structure caused by long-term high stress, and extend the service life of the bridge.
[0095] As Figure 1As shown, the arch bridge hanger anchoring structure further includes a rigid support member 10. The rigid support member 10 is sleeved on the hanger 1, and the rigid support member 10 is located between the first anchor plate 2 and the second anchor plate 9.
[0096] The rigid support member 10 provides additional support for the hanger 1, enhances the stability of the hanger 1 when bearing loads, helps reduce the bending and vibration of the hanger 1, and improves the overall stiffness and load-bearing capacity of the bridge.
[0097] In this embodiment, the rigid support member 10 is a steel sleeve. The steel sleeve has high strength and toughness and can play an effective supporting and strengthening role. Preferably, the steel sleeve can be specially treated (such as galvanized, sprayed with plastic, etc.) to resist the erosion of the external environment and ensure long-term use performance.
[0098] The serial numbers of the embodiments of the present application above are only for description and do not represent the superiority or inferiority of the embodiments. The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
