Description

Technical Field

[0001] This application relates to the field of bridge vibration reduction technology, and in particular to a bridge vibration reduction tenon device. Background Technology

[0002] As bridge engineering continues to develop towards longer spans, heavier loads, and higher seismic intensity areas, seismic action has become one of the most important controlling factors affecting the structural safety of bridges. Vibration damping tenons, as a highly efficient seismic energy dissipation component, rely on their own elasto-plastic deformation to dissipate seismic input energy, effectively reducing the relative displacement of the beam, and are widely used in various beam bridge seismic-resistant systems. However, engineering applications and related research indicate that traditional vibration damping tenons still have significant shortcomings in terms of structural form, load-bearing performance, and construction and installation.

[0003] Traditional bridge vibration damping tenons are often directly welded to the base plate and movable guide components. Under reciprocating seismic loads, stress concentration at the welded areas becomes prominent, making them prone to cracking or even breakage, leading to the failure of the vibration damping tenons. The movable guide components, made of a single all-steel structure, rigidly connect multiple rows of vibration damping tenons, restricting the bending deformation capacity of individual tenons and causing uneven deformation among them, thus reducing overall energy dissipation. The fixed guide plate, with its integrated structure, is large and heavy, increasing the workload and construction difficulty of on-site installation. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides a bridge vibration damping tenon device, which can solve the problem that in the related technology, the vibration damping tenon of the traditional bridge vibration damping tenon device is often directly welded to the base plate and movable guide component. Under the action of reciprocating earthquake, the stress concentration at the welded part is prominent, which is very easy to crack or even break, causing the vibration damping tenon to fail.

[0046] See Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, this application embodiment provides a bridge vibration damping tenon device, including:

[0047] The lower mounting base includes a lower embedded plate 7 and a lower base plate 6 fixed to the top of the lower embedded plate 7. The lower embedded plate 7 is used to be embedded in the top of the bridge pier or the top surface of the tower beam. The lower embedded plate 7 and the lower base plate 6 are detachably connected to each other. The lower base plate 6 is detachably connected to the lower embedded plate 7 by a lower fastener 8.

[0048] The upper mounting base includes an upper embedded plate 1 and a fixed guide member 3 fixed to the bottom of the upper embedded plate 1 and having a longitudinal groove. The upper embedded plate 1 is used to be embedded in the bottom surface of the main beam of the bridge, and the upper embedded plate 1 is located directly above the lower embedded plate 7 and the lower bottom plate 6.

[0049] The energy-dissipating component includes a movable guide 4 located within a longitudinal groove, and multiple rows of damping tenons 5 that pass through the movable guide 4 and the lower base plate 6 at their upper and lower ends, respectively. The movable guide 4 slides longitudinally within the longitudinal groove, allowing the main beam of the bridge to extend and retract longitudinally while facilitating the replacement of the energy-dissipating component and the lower base plate 6.

[0050] The upper and lower ends of the shock-absorbing tenon 5 are inserted into the movable guide 4 and the lower base plate 6, respectively. When the main beam of the bridge is subjected to seismic action, the upper and lower ends of the shock-absorbing tenon 5 can overcome the shear force at the connection between the shock-absorbing tenon 5 and the movable guide 4 and the lower base plate 6 when the energy dissipates and the shock-absorbing tenon 5 undergoes bending deformation.

[0051] The bridge damping tenon device of this application embodiment is used for transverse damping and energy dissipation of the main girder of a bridge. The movable guide 4 of the energy dissipation component can adapt to the temperature expansion and contraction displacement of the main girder in the longitudinal direction and can withstand the seismic force in the transverse direction of the main girder. Under the action of an earthquake, the multi-row damping tenons 5 of the energy dissipation component will bend and deform, thereby realizing energy dissipation and damping.

[0052] Among them, the upper and lower ends of the multi-row shock-absorbing tenon 5 of the energy-consuming component are inserted into the movable guide 4 and the lower base plate 6 respectively. When the shock-absorbing tenon 5 bends and deforms under the action of an earthquake, the upper and lower ends of the shock-absorbing tenon 5 can resist the horizontal shear force, which improves the structural strength between the shock-absorbing tenon 5 and the movable guide 4 and the lower base plate 6, and can solve the problem of existing shock-absorbing tenons breaking at the ends due to stress concentration.

[0053] In some alternative embodiments: see Figures 1 to 9 As shown, this application embodiment provides a bridge vibration damping tenon device. The lower base plate 6 of the bridge vibration damping tenon device has a plurality of lower anchoring holes arranged in an array. The number of lower anchoring holes is the same as the number of vibration damping tenons 5. The movable guide 4 has a plurality of upper anchoring holes 42 arranged in an array.

[0054] The upper end of each damping tenon 5 is anchored in the upper anchoring hole 42, and the lower end of the damping tenon 5 is anchored in the lower anchoring hole. The damping tenon 5 includes a damping tenon energy dissipation section 51, an upper anchoring section 53 connected to the top of the damping tenon energy dissipation section 51, and a lower anchoring section 52 connected to the bottom of the damping tenon energy dissipation section 51.

[0055] The diameter of the shock-absorbing section 51 gradually decreases from the lower anchoring section 52 toward the upper anchoring section 53. The upper anchoring section 53 is anchored in the upper anchoring hole 42 of the movable guide 4, and the lower anchoring section 52 is anchored in the lower anchoring hole of the lower base plate 6.

[0056] The upper anchoring section 53 has a bevel at the end furthest from the shock-absorbing tenon energy-dissipating section 51. The bevel of the upper anchoring section 53 is welded to the movable guide member 4 by a full penetration bevel weld to improve the connection strength and prevent them from separating. The lower anchoring section 52 has a bevel at the end furthest from the shock-absorbing tenon energy-dissipating section 51. The bevel of the lower anchoring section 52 is welded to the lower base plate 6 by a full penetration bevel weld to improve the connection strength and prevent them from separating.

[0057] The shape of the shock-absorbing tenon energy-dissipating section 51 is a variable cross-section design based on the principle of equal stress. Under the action of force, the shock-absorbing tenon energy-dissipating section 51 can achieve simultaneous yielding of the entire cross-section, thereby improving the energy dissipation efficiency of the shock-absorbing tenon 5 and saving energy-consuming steel.

[0058] In this embodiment, the upper anchoring section 53 is anchored within the upper anchoring hole 42 of the movable guide member 4 and is welded together with each other via a penetration groove weld. This not only improves the horizontal shear resistance but also enhances the vertical anti-detachment capability. The lower anchoring section 52 is anchored within the lower anchoring hole of the lower base plate 6 and is welded together with each other via a penetration groove weld. This not only improves the horizontal shear resistance but also enhances the vertical anti-detachment capability.

[0059] In some alternative embodiments: see Figure 6 , Figure 7 and Figure 9 As shown, this application embodiment provides a bridge vibration damping tenon device. The lower base plate 6 of the bridge vibration damping tenon device has multiple lower anchoring holes with internal threads. The lower anchoring holes of the lower base plate 6 are all threaded with external threaded sleeves 9. The lower end of the vibration damping tenon 5 is fixed in the external threaded sleeve 9.

[0060] In this embodiment, the lower end of the shock-absorbing tenon 5 is fixed inside the external threaded sleeve 9. They can be connected by threads or welding. The external threaded sleeve 9 is connected to the lower anchoring hole of the lower base plate 6 by threads. The external threaded sleeve 9 serves as a connector between the shock-absorbing tenon 5 and the lower base plate 6. When the shock-absorbing tenon 5 is damaged or deformed, the external threaded sleeve 9 can be removed and a new shock-absorbing tenon 5 can be replaced on the lower base plate 6.

[0061] In some alternative embodiments: see Figure 1 , Figure 2 and Figure 5 As shown, this application embodiment provides a bridge damping tenon device. The fixed guide 3 of the bridge damping tenon device includes a left limiting block 31 and a right limiting block 32 that are symmetrically and spaced apart. The left limiting block 31 and the right limiting block 32 form a longitudinal groove.

[0062] Both the left limiting block 31 and the right limiting block 32 include a horizontal mounting plate 33 and a vertical limiting plate 34 that are perpendicularly connected to each other, as well as a reinforcing plate 35 connecting the horizontal mounting plate 33 and the vertical limiting plate 34. The horizontal mounting plates 33 of both the left limiting block 31 and the right limiting block 32 are detachably connected to the upper embedded plate 1 by upper fasteners 2.

[0063] In this embodiment of the application, a single longitudinal groove is formed between the left limiting block 31 and the right limiting block 32, and the movable guide 4 is slidably connected within the single longitudinal groove formed between the left limiting block 31 and the right limiting block 32. While ensuring force transmission in the transverse direction and free sliding in the longitudinal direction, the left limiting block 31 and the right limiting block 32 can reduce volume and weight, facilitating the installation of the actual bridge.

[0064] In some alternative embodiments: see Figure 1 , Figure 2 , Figure 4 andFigure 5 As shown in the figure, this application embodiment provides a bridge vibration damping tenon device. The movable guide 4 of the bridge vibration damping tenon device includes multiple spaced guide blocks 41, and adjacent guide blocks 41 are fixedly connected by rubber blocks 43. Each guide block 41 is provided with an upper anchoring hole 42, and the top of each row of vibration damping tenons 5 is anchored in the upper anchoring hole 42 of the same guide block 41.

[0065] The movable guide 4, which consists of multiple guide blocks 41 and rubber blocks 43, has a rectangular block structure. The side of the movable guide 4 closest to the left limit block 31 and the right limit block 32 is an arc surface, which reduces the friction between the two sides of the movable guide 4 and the left limit block 31 and the right limit block 32, and facilitates the bending energy dissipation of the shock-absorbing tenon.

[0066] In this embodiment, two adjacent guide blocks 41 are fixedly connected by a rubber block 43. While transmitting the transverse force of the bridge, the rubber block 43 can undergo shear deformation, thereby adapting to the deformation differences of the damping tenons 5 in each row of the transverse direction. This can effectively solve defects such as stress concentration, deformation incoordination and inconvenient installation, and significantly improve the seismic performance and construction efficiency of the bridge.

[0067] In some alternative embodiments: see Figures 5 to 9 As shown, another embodiment of this application provides a bridge vibration damping tenon device. The fixed guide 3 of the bridge vibration damping tenon device includes multiple limiting baffles 36 fixed at intervals on the bottom surface of the upper embedded plate 1. A longitudinal sliding groove is formed between two adjacent limiting baffles 36; n-1 longitudinal sliding grooves are formed between n limiting baffles 36.

[0068] Multiple rows of mortises are formed on the upper embedded plate 1. The top of the limiting baffle 36 is provided with multiple tenons that can be inserted into the mortises, and the limiting baffle 36 is welded and fixed to the upper embedded plate 1. The movable guide component 4 includes multiple guide blocks 41 arranged at intervals, and each guide block 41 is located in multiple longitudinal grooves. Each guide block 41 is provided with an upper anchoring hole 42, and the top of each row of shock-absorbing tenons 5 is anchored in the upper anchoring hole 42 of the same guide block 41.

[0069] Each guide block 41 is a rectangular block structure, and the side of each guide block 41 closest to the limiting baffle 36 is an arc surface. The guide block 41 and the limiting baffle 36 are in contact with each other using an arc surface, thereby reducing the friction between the two sides of the guide block 41 and the limiting baffle 36, which facilitates the bending energy dissipation of the shock-absorbing tenon.

[0070] The movable guide 4 in this embodiment is composed of multiple spaced guide blocks 41. Each guide block 41 is anchored to the top of each row of damping tenons 5 through the upper anchoring hole 42 and then slides in the longitudinal groove. While transmitting the transverse force of the bridge, each guide block 41 can also adapt to the deformation differences of each row of damping tenons 5 in the transverse direction. This can effectively solve the defects such as stress concentration, deformation incoordination and inconvenient installation, and significantly improve the seismic performance and construction efficiency of the bridge.

[0071] In some alternative embodiments: see Figures 1 to 9 As shown, based on the actual parameters of a cable-stayed bridge pier with a main span greater than 500m, the selection and specifications of each component of the vibration damping tenon device for this bridge are determined as follows:

[0072] Upper Embedded Plate 1: Made of Q345B steel plate with specifications of 3000mm×800mm×30mm, it is embedded in the bottom surface of the main beam of the bridge and fixed to the embedded parts of the main beam by M40 high-strength anchor bolts.

[0073] Lower embedded plate 7: Made of Q235B steel plate with specifications of 2500mm×700mm×25mm, it is embedded in the top of the bridge pier or the top surface of the tower beam.

[0074] Fixed guide component 3: It is made of Q355B steel plate, welded and formed, with a length of 2000mm and a width of 800mm. It is provided with reserved holes for inserting the upper fastener 2.

[0075] The movable guide component 4: the guide block 41 is made of Q235B steel with a cross section of 100mm×100mm×15mm; the rubber block 43 is made of styrene-butadiene rubber with a thickness of 30mm and a shear modulus of 5.0MPa.

[0076] Vibration damping tenon 5: Vibration damping tenon energy dissipation section 51 is made of Q460B high-strength steel variable cross-section round steel, with a bottom diameter D1=300mm, a top diameter D2=150mm, and a total length L=1500mm.

The upper and lower ends of the multi-row damping tenons 5 of the energy dissipation component are respectively inserted into the movable guide 4 and the lower base plate 6. When the damping tenon 5 undergoes bending deformation under seismic action, the upper and lower ends of the damping tenon 5 can resist horizontal shear force, which improves the structural strength between the damping tenon 5, the movable guide 4 and the lower base plate 6, and can solve the problem of existing damping tenons breaking at the ends due to stress concentration.
