DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] The embodiments of the present application provide a steel structure cable tower anchoring system with asymmetric arrangement, which can solve the defects that the steel anchor beam is placed on the steel corbel, the steel anchor beam and the corbel are connected in the mode that the limiting devices in the longitudinal and transverse directions are arranged at both ends, and the position of the steel anchor beam is out of control and the safety and stability are low in the extreme working conditions such as broken cable.

[0026] Referring to Figures 1 to 4As shown, the embodiment of the present application provides a kind of asymmetrically arranged steel structure cable tower anchoring system, comprising: cable tower 1 and corbel 2 and steel anchor beam 3, cable tower 1 is arranged multiple along longitudinal bridge direction, and cable tower 1 has two oppositely arranged tower wall;Corbel 2 is installed on any one side tower wall, and multiple are arranged along the height direction of cable tower 1;Steel anchor beam 3 one end is movably connected with corbel 2, and the other end is fixedly connected with the tower wall of cable tower 1.

[0027] By the asymmetrically arranged structure of the two ends of steel anchor beam 3, the demand of bridge load can be better adapted, and the applicability of the system is improved.The movable connection design of the end of steel anchor beam 3 connected with corbel 2 enables the system to have certain activity space when stressed, i.e., in the broken cable condition, the movable connection of steel anchor beam 3 and corbel 2 enables longitudinal free sliding of steel anchor beam 3, simultaneously transmits the vertical load between steel anchor beam 3 and corbel 2, and restrains the horizontal displacement and vertical displacement of steel anchor beam 3, thereby enhancing the flexibility and reliability of the system.The other end of steel anchor beam 3 is fixed with cable tower 1, which can transmit the load on steel anchor beam 3 to the tower wall of cable tower 1, and simplifies the force transmission path of anchoring system.

[0028] In the present application, the end of steel anchor beam 3 connected with corbel 2 is movably connected, so that end plate 301 is arranged at the end of steel anchor beam 3 close to corbel 2, and end plate 301 can reinforce steel anchor beam 3 and improve the stability of steel anchor beam 3.

[0029] Although, in other embodiments, the connection mode between steel anchor beam 3 and corbel 2 includes automatic sliding type, free sliding type, and steel anchor beam 3 is placed on corbel 2, and longitudinal bridge direction and horizontal bridge direction limiting devices are arranged at the two ends, this connection mode enables steel anchor beam 3 to bear most of the horizontal component force under dead load and operating load, and improves the stress state of concrete tower wall, however, broken cable and other extreme conditions may cause the position of steel anchor beam 3 to be out of control.

[0030] Or it includes the type of sliding first and then locking: in the construction process, one end of steel anchor beam 3 is locked with corbel 2, and the other side of steel anchor beam 3 is locked with corbel 2 after the stay cable is tensioned to the specified cable force, in the construction process, steel anchor beam 3 bears the horizontal component force of stay cable alone, and in the operation stage, steel anchor beam 3 and tower wall of cable tower 1 bear the horizontal component force of stay cable together, this connection mode increases the reliability of the connection of anchoring zone components, however, the tower wall bears larger horizontal component force in the operation process, and the steel bars of both sides of the tower wall still need to be arranged stronger.

[0031] And including the constraint sliding type: the type of steel anchor beam 3 is provided with a limiting mechanism between the corbel 2 and the anchor beam, allowing the steel anchor beam 3 to move on the corbel 2 along the longitudinal bridge, which can eliminate the secondary internal force caused by the temperature and concrete tower wall shrinkage and creep of the system, however, under the action of broken cable working condition, the side span side and the side span side concrete tower wall may bear the broken cable force, in order to ensure the safety of the structure under the broken cable working condition, the two sides of the tower wall still need to be configured with strong steel bars to resist the broken cable force, thereby reducing the economy of the structure.

[0032] In the present application, one end of the steel anchor beam 3 is set as a movable end, and the other end is set as a fixed end. Whether in the broken cable working condition or in the operation stage, the load is borne by the tower wall on the fixed end side of the steel anchor beam 3, so only the tower wall on the fixed end side of the steel anchor beam 3 needs to be strengthened, and the tower wall on the movable end side of the steel anchor beam 3 hardly bears the longitudinal bridge horizontal component of the cable in the operation condition or the broken cable working condition, thereby significantly reducing the amount of stirrup, reducing the construction difficulty of the tower wall, thereby ensuring the construction quality, and having good economic benefit.

[0033] In the present application, the corbel 2 is composed of a top plate 20, a side plate 21 and a bottom plate 22. The side plate 21 is connected between the top plate 20 and the bottom plate 22, and the top plate 20, the side plate 21 and the bottom plate 22 jointly constitute the main structure of the corbel 2, and the connection therebetween ensures the overall stability and bearing capacity of the corbel 2. A first stiffening rib 23 is further provided on the side plate 21, which can significantly improve the bending resistance and shear resistance of the side plate 21. Then a sliding groove 40 is provided on the corbel 2, specifically on the top plate 20. A sliding sheet 41 is connected in the sliding groove 40. One end of the steel anchor beam 3 is placed on the sliding sheet 41. The sliding sheet 41 is composed of two layers of structure. The structure in the bottom layer is made of stainless steel material, which has a small low friction coefficient, so as to avoid the sliding sheet 41 from sliding out of the sliding groove 40. The upper layer structure is made of a material with a small friction coefficient, so that the steel anchor beam 3 has better moving ability on the sliding sheet 41. Therefore, under the action of the sliding sheet 41, the steel anchor beam 3 can effectively move on the corbel 2, and direct contact between the steel anchor beam 3 and the corbel 2 is avoided to cause abrasion. The transverse bridge horizontal load generated by the corbel 2 can be transmitted to the tower wall of the cable tower 1 through the top plate 20, realizing the function of restraining the transverse deformation of the steel anchor beam 3. When the steel anchor beam 3 appears upward displacement on one side in the longitudinal bridge due to broken cable and other extreme working conditions, the top plate 20 can effectively restrain the upward deformation of the steel anchor beam 3, preventing the steel anchor beam 3 from rotating.

[0034] In the present application, when the steel anchor beam 3 moves upward on one side of the longitudinal bridge due to extreme conditions such as broken cables, the top plate 20 can effectively constrain the upward deformation of the steel anchor beam 3, preventing the steel anchor beam 3 from rotating. Therefore, in order to avoid the steel anchor beam 3 resisting the tower wall of the cable tower 1 under all loads, the horizontal component force generated by the cable-stayed bridge in the longitudinal bridge direction is avoided, and a deformation space 10 is provided between the bracket 2 and the tower wall of the cable tower 1. The size of the deformation space 10 in the longitudinal bridge direction is greater than the sum of the longitudinal bridge deformation of the steel anchor beam 3 under all possible loads such as dead load, shrinkage and creep, live load, temperature, broken cable force, etc. In the present application, a mounting space 30 is also provided between the bracket 2 and the steel anchor beam 3. When the sliding piece 41 needs to be replaced, the top plate 20 of the bracket 2 and the top plate 20 of the steel anchor beam 3 can be used as the fulcrum of tools including but not limited to jacks, etc. The mounting space 30 is used to place the jack, greatly improving the convenience of later maintenance and repair of the steel anchor beam 3.

[0035] In the present application, anchor assemblies are provided on both sides of the tower wall of the cable tower 1, one side of the anchor assembly is used to fix the bracket 2 on the cable tower 1, and the other side of the anchor assembly is used to fix the steel anchor beam 3 on the cable tower 1. The setting of the anchor assembly makes the bracket 2 and the steel anchor beam 3 can be independently fixed and adjusted on the cable tower 1. This design not only simplifies the structure, but also improves the flexibility and adaptability of the anchoring system. The bracket 2 at one end of the traditional steel anchor beam 3 is cancelled, and the steel anchor beam 3 can be anchored into the tower wall through the anchor assembly, directly transmitting the load of the steel anchor beam 3 to the tower wall, simplifying the force transmission path of the anchoring system, reducing the processing difficulty of the anchoring system, reducing the amount of steel, and having good economic benefits.

[0036] In the present application, the anchor assembly includes a first anchor plate 50 and a first shear key 51. The first anchor plate 50 is embedded in the tower wall on both sides of the cable tower 1, and one side of the first anchor plate 50 is welded and fixed with the bracket 2, and the other side of the first anchor plate 50 is welded and fixed with the steel anchor beam 3. The first shear key 51 is embedded in the cable tower 1 and fixed with the first anchor plate 50, and the first shear key 51 includes but is not limited to shear pins. The first anchor plate 50 is embedded in the tower wall on both sides of the cable tower 1 as the basis for connecting the bracket 2 and the steel anchor beam 3, and is welded and fixed. The first anchor plate 50 can ensure that the connection between the bracket 2 and the steel anchor beam 3 and the cable tower 1 is firm and reliable, and is not easy to loosen. In use, the first anchor plate 50 can bear the load from the bracket 2 and the steel anchor beam 3 and effectively transmit it to the tower wall of the cable tower 1, which helps to reduce local stress concentration and improve the carrying capacity of the entire structure. The first shear key 51 is embedded in the cable tower 1 and fixed with the first anchor plate 50, which can effectively resist the shear force from the bracket 2 and the steel anchor beam 3, preventing shear failure of the structure under stress. Through the joint action of the first anchor plate 50 and the first shear key 51, the safety and reliability of the entire structure can be significantly improved.

[0037] In the present application, the first anchor plate 50 is also provided with a reinforcing assembly, and at least one set of reinforcing assemblies is arranged on the first anchor plate 50 fixed with the corbel 2, and at least two sets of reinforcing assemblies are arranged on the first anchor plate 50 fixed with the steel anchor beam 3. The addition of the reinforcing assembly significantly enhances the load-bearing capacity of the first anchor plate 50, making the connection of the corbel 2 and the steel anchor beam 3 with the tower 1 more stable and reliable. Especially in extreme working conditions, the reinforcing assembly can ensure the reliability and safety of the connection. Moreover, in both broken cable conditions and operation stages, the tower wall at the movable end of the steel anchor beam 3 hardly bears the longitudinal bridge horizontal component of the stay cable in both operation conditions and broken cable conditions, thereby significantly reducing the amount of stirrups, reducing the construction difficulty of the tower wall, thereby ensuring the construction quality, and having good economic benefits; the tower wall at the fixed end of the steel anchor beam 3 bears the main load, so the vertical addition of the reinforcing assembly on this side strengthens the tower wall at the fixed end of the steel anchor beam 3, simplifies the anchoring structure, reduces the processing difficulty of the anchoring system, reduces the amount of steel, and has good economic benefits.

[0038] Each set of reinforcing assemblies arranged includes a second anchor plate 60 and a second shear key 61, the second anchor plate 60 is embedded in the tower 1 and fixed with the first anchor plate 50, and the second shear key 61 is embedded in the tower 1 and fixed with the second anchor plate 60. The addition of the second anchor plate 60 and the second shear key 61 provides additional connection points for the tower 1 structure, which helps to disperse and transfer loads, thereby enhancing the stability of the structure.

[0039] In the broken cable condition, the anchoring assembly and the reinforcing assembly work together to constrain the possible upward vertical displacement of the steel anchor beam 3, prevent the steel anchor beam 3 from rotating, and ensure the stability of the steel anchor beam 3 in the broken cable condition.

[0040] In the present application, a plurality of second stiffening ribs 300 are connected to the two side webs of the steel anchor beam 3. The second stiffening rib 300 serves as a strip-shaped reinforcing member, which can significantly increase the cross-sectional area and stiffness of the steel anchor beam 3 by adding transverse or longitudinal ribs on the steel anchor beam 3, thereby improving the stability and load-bearing capacity of the steel anchor beam 3. This helps to prevent the steel anchor beam 3 from losing stability when subjected to external forces, ensuring the overall safety of the structure.

[0041] In the present application, a cable anchoring assembly is also provided at both ends of the steel anchor beam 3, which includes a first support plate 70, a stiffening plate 71, and an anchor backing plate 72. The first support plate 70 is connected to the web of the steel anchor beam 3 on both sides. The stiffening plate 71 is fixed to the first support plate 70 on both sides. The anchor backing plate 72 is connected between the first support plate 70 and the stiffening plate 71, and the bottom surface of the first support plate 70 away from the corbel 2 extends to the first anchor plate 50 for fixation. The addition of the cable anchoring assembly, especially the combined use of the first support plate 70, the stiffening plate 71, and the anchor backing plate 72, significantly enhances the stiffness of the steel anchor beam 3 and the connecting area between the steel anchor beam 3 and the tower 1. This helps to resist deformation caused by external loads and improves the stability of the overall structure. Moreover, the bottom surface of the first support plate 70 away from the corbel 2 extends to the first anchor plate 50 for fixation, so the cable force of the stay cable can be directly transmitted to the first anchor plate 50 through the first support plate 70, and then to the tower wall of the tower 1, simplifying the force transmission path of the steel anchor beam 3 and achieving good economic benefits.

[0042] In addition, in order to strengthen the strength of the end of the steel anchor beam 3 fixed to the tower wall of the tower 1, a second support plate 73 is also provided at the end of the steel anchor beam 3 away from the corbel 2. The two sides of the second support plate 73 are connected to the web of the steel anchor beam 3, and the bottom surface of the second support plate 73 extends to the first anchor plate 50 for fixation.

[0043] In the broken cable condition, when the stay cable on one side of the longitudinal bridge breaks, the stay cable on one side of the longitudinal bridge will transmit the cable force to the first anchor plate 50 on the side away from the corbel 2 through the first support plate 70 and the second support plate 73, and then transmit the cable force to the tower wall of the tower 1. When the stay cable on the other side of the longitudinal bridge breaks, the stay cable on the other side of the longitudinal bridge will transmit the cable force to the steel anchor beam 3 through the first support plate 70, further transmit the cable force to the first anchor plate 50 on the side away from the corbel 2, and finally transmit the cable force to the tower wall of the tower 1. Therefore, no matter which side appears the broken cable condition, the broken cable force will not act on the tower wall of the tower 1 on the side of the corbel 2, but only on the tower wall of the tower 1 fixed to the steel anchor beam 3. When designing the tower wall, only the tower wall of the tower 1 at the fixed end of the steel anchor beam 3 needs to be designed considering the broken cable condition, simplifying the reinforcement arrangement of the tower wall of the tower 1.

[0044] In the present application, the first anchor plate 50 and the second anchor plate 60 are also provided with steel bar holes 8 and air vents 9. The steel bar holes 8 are used to pass through steel bars to firmly connect the first anchor plate 50 and the second anchor plate 60 with the concrete structure of the cable tower 1. This connection method not only ensures the continuity of the steel bars, but also ensures that the cable tension can be uniformly transmitted to the concrete structure of the cable tower 1, thereby improving the anchoring reliability of the first anchor plate 50 and the second anchor plate 60. The air vents 9 are provided to discharge the gas in the concrete and prevent the gas from accumulating to form a cavity under the embedded part. This helps to ensure the compactness and integrity of the concrete and improve the adhesion of the first anchor plate 50 and the second anchor plate 60 to the concrete.
