Description
Technical Field
[0001] The utility model relates to the technical field of bridge steel structures, in particular to a steel structure clamping block bridge anti-falling beam device that utilizes displacement energy dissipation. Background Technique
[0002] Bridge steel structures refer to bridge structures mainly composed of steel, which have the characteristics of high strength, light self-weight, fast construction speed, good durability, etc. Steel structure bridges include various types such as steel truss bridges, steel box girder bridges, and steel plate girder bridges.
[0003] If a bridge relies solely on simple cross bracing to resist vibration during natural disasters such as earthquakes, it may not provide sufficient stability and stiffness, resulting in excessive displacement and deformation of the bridge under the action of earthquake forces, thus affecting the use function of the bridge and even causing the structure to fall. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides a steel structure clamping block bridge anti-falling beam device that utilizes displacement energy dissipation.
[0005] The utility model is realized by the following technical solutions: a steel structure clamping block bridge anti-falling beam device that utilizes displacement energy dissipation, including a main support steel. On both sides of the outer surface of the main support steel, connection clamping blocks are provided, and a shock absorption component is arranged on the upper surface of the main support steel;
[0006] The shock absorption component includes rubber cushion blocks. The rubber cushion blocks are respectively fixedly connected to both sides of the upper surface of the main support steel. The top of the rubber cushion blocks is fixedly connected with side support beams. In the middle of the upper surface of the main support steel, an energy dissipator body is fixedly connected, and the top of the energy dissipator body is fixedly connected with a middle support beam.
[0007] Through the above technical solutions, the rubber cushion blocks can effectively absorb and disperse seismic energy, reducing the dynamic impact on the bridge structure during an earthquake. The side support beams strengthen the stability on both sides of the bridge, effectively restricting the horizontal displacement of the bridge beam body, and forming an effective seismic barrier by connecting with the rubber cushion blocks. The energy dissipator can dissipate energy, reducing the response intensity of the bridge structure, thereby reducing the risk of damage. The middle support beam provides key support for the central area of the bridge, enhancing the torsional and bending resistance of the entire bridge structure, and assisting the energy dissipator body to share part of the seismic load, reducing the burden on a single energy dissipator.
[0008] As a further improvement of the above solution, through holes are opened in the middle and on both sides of the upper surfaces of the side support beams and the middle support beam.
[0009] Through the above technical solution, the through slot enables the beam to produce certain ductile deformation when subjected to lateral or longitudinal loads. The ductile deformation can dissipate seismic energy, thereby improving the seismic resistance of the structure.
[0010] As a further improvement of the above solution, a reinforcing cross beam is arranged inside the through slot.
[0011] Through the above technical solution, the reinforcing cross beam can enhance the local stiffness of the beam body, especially near the through slot, reduce the structural weakening caused by slotting, and through the structural cooperation between the reinforcing cross beam, the side support beam and the central support beam, the load-bearing capacity of the beam body for vertical and horizontal loads can be improved, especially the resistance to dynamic loads and seismic forces.
[0012] As a further improvement of the above solution, grooves are formed on the surface of the connecting block, and both ends of the reinforcing cross beam are clamped inside the grooves.
[0013] Through the above technical solution, by clamping both ends of the reinforcing cross beam in the grooves on the connecting block, the horizontal movement of the reinforcing cross beam can be effectively restricted, improving the stability of the entire bridge structure. Under the action of an earthquake, the clamping relationship between the groove and the reinforcing cross beam can dissipate part of the seismic energy and reduce the damage of the earthquake to the steel structure.
[0014] As a further improvement of the above solution, extension blocks are fixedly connected to both sides of the lower surface of the main support steel, and the extension blocks are made of steel.
[0015] Through the above technical solution, the steel extension blocks can increase the vertical load-bearing capacity of the bridge structure, especially for the case of bearing large vertical loads, providing additional support and reinforcement. The extension blocks can improve the lateral stability of the bridge structure, especially when arranged on both sides of the lower surface of the main support steel, and can resist forces from the horizontal direction.
[0016] As a further improvement of the above solution, strength steel bars are fixedly connected to the surface of the extension blocks.
[0017] Through the above technical solution, the high ductility of the steel bars can produce certain plastic deformation under the action of loads, thereby dissipating energy and improving the seismic performance of the bridge.
[0018] As a further improvement of the above solution, pier caps are fixedly connected to the bottom of the extension blocks, and the main support steel is fixedly connected to the pier caps through the extension blocks.
[0019] Through the above technical solution, this method can effectively transfer the load borne by the main support steel to the pier caps, thereby improving the load-bearing capacity of the entire bridge structure. During an earthquake, it helps to prevent relative displacement between the main support steel and the pier caps.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

The central support beam provides key support for the central area of the bridge, enhances the torsional and bending resistance of the entire bridge structure, and assists the energy dissipator body to share part of the seismic load, reducing the burden on a single energy dissipator.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features.
[0030] Embodiment:
[0031] Please refer to Figures 1-5, A steel structure clamping block bridge anti-falling beam device using displacement energy dissipation in this embodiment includes a main support steel 1. On both sides of the outer surface of the main support steel 1, connecting blocks 2 are provided, and a shock absorption component 3 is arranged on the upper surface of the main support steel 1;
[0032] The shock absorption component 3 includes rubber cushion blocks 301. The rubber cushion blocks 301 are respectively fixedly connected to both sides of the upper surface of the main support steel 1. A side support beam 302 is fixedly connected to the top of the rubber cushion block 301. A energy dissipator body 303 is fixedly connected to the middle of the upper surface of the main support steel 1. A central support beam 304 is fixedly connected to the top of the energy dissipator body 303. The rubber cushion blocks 301 can effectively absorb and disperse seismic energy, reducing the dynamic impact on the bridge structure during an earthquake. The side support beam 302 strengthens the stability on both sides of the bridge, effectively restricting the horizontal displacement of the bridge beam body, and forms an effective seismic barrier by connecting with the rubber cushion blocks 301. The energy dissipator can dissipate energy, reduce the response intensity of the bridge structure, and thus reduce the damage risk. The central support beam 304 provides key support for the central area of the bridge, enhancing the torsional and flexural resistance of the entire bridge structure, and assisting the energy dissipator body 303 to share part of the seismic load, reducing the burden on a single energy dissipator.
[0033] Through slots 4 are opened in the middle and on both sides of the upper surfaces of the side support beam 302 and the central support beam 304. The through slots 4 enable the beam to produce certain ductile deformation when subjected to transverse or longitudinal loads. The ductile deformation can dissipate seismic energy, thereby improving the seismic capacity of the structure.
[0034] Reinforcing cross beams 5 are arranged inside the through slots 4. The reinforcing cross beams 5 can enhance the local stiffness of the beam body, especially near the through slots, reducing the structural weakening caused by slotting. And through the structural cooperation between the reinforcing cross beams 5 and the side support beam 302 and the central support beam 304, the load-bearing capacity of the beam body for vertical and horizontal loads can be improved, especially the resistance to dynamic loads and seismic forces.
[0035] Grooves 6 are opened on the surface of the connecting blocks 2. Both ends of the reinforcing cross beam 5 are clamped inside the grooves 6. By clamping both ends of the reinforcing cross beam 5 in the grooves 6 on the connecting blocks 2, the horizontal movement of the reinforcing cross beam 5 can be effectively restricted, improving the stability of the entire bridge structure. Under the action of an earthquake, the clamping relationship between the grooves 6 and the reinforcing cross beam 5 can dissipate part of the seismic energy and reduce the damage to the steel structure caused by the earthquake.
[0036] Extension blocks 7 are fixedly connected to both sides of the lower surface of the main supporting steel 1. The extension blocks 7 are made of steel. The steel extension blocks 7 can increase the vertical bearing capacity of the bridge structure, especially for situations where large vertical loads are applied, and provide additional support and reinforcement. The extension blocks 7 can improve the lateral stability of the bridge structure, especially when they are arranged on both sides of the lower surface of the main supporting steel 1, they can resist forces from the horizontal direction.
[0037] The surface of the extension block 7 is fixedly connected with a strength steel bar 8. The high ductility of the steel bar can produce a certain plastic deformation under the action of load, thereby dissipating energy and improving the seismic performance of the bridge.
[0038] The bottom of the extension block 7 is fixedly connected to the pier 9, and the main support steel 1 is fixedly connected to the pier 9 through the extension block 7. This method can effectively transfer the load borne by the main support steel 1 to the pier 9, thereby improving the bearing capacity of the entire bridge structure. When an earthquake occurs, it helps to prevent relative displacement between the main support steel 1 and the pier 9.
[0039] The implementation principle of a steel structure block bridge anti-falling beam device using displacement energy dissipation in the embodiment of the present application is as follows: a connecting block 2 is provided on both sides of the main support steel 1 for connecting with other structural members, and a shock absorbing assembly 3 is provided on the main support steel 1, including a rubber pad 301, a side support beam 302, an energy dissipator body 303 and a central support beam 304. The rubber pad 301 helps to absorb and disperse seismic energy, and the side support beam 302 and the central support beam 304 provide additional stability and support. The energy dissipator body 303 helps to dissipate energy and reduce the response strength of the bridge structure during an earthquake. The through groove 4 in the shock absorbing assembly 3 allows the beam body to produce ductile deformation when subjected to force to dissipate seismic energy. The reinforcement beam 5 is placed in the through groove 4, which can enhance the local stiffness and improve the bearing capacity of the beam body for various loads. The groove 6 on the connecting block 2 cooperates with the reinforcement beam 5 to limit its horizontal movement, improve the overall stability, and dissipate part of the energy during an earthquake. Steel extension blocks 7 are provided on both sides of the lower surface of the main support steel 1 to increase the vertical bearing capacity and lateral stability. Strength steel bars 8 are connected to the extension blocks 7, which use their high ductility to generate plastic deformation and energy dissipation under load. Finally, the bottom of the extension blocks 7 is connected to the piers 9 to provide a solid foundation support for the bridge, thereby improving the overall stability and seismic performance of the steel structure.
