Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling beam devices, in particular to a side-mounted anti-buckling damping anti-falling beam device. Background Art

[0002] In bridge engineering, beam-drop stoppers are a key safety component, crucial for preventing lateral or longitudinal displacement of bridges under earthquakes, wind, or other external forces, preventing beams from falling off piers or abutments, and ensuring the stability and safety of bridge structures. However, traditional beam-drop stopper design and material selection present a series of challenges.

[0003] Conventional beam-fall prevention blocks are primarily constructed of concrete and I-beams, materials generally considered rigid in mechanics. During an earthquake, the intense impact of seismic waves can cause the beam to collide directly with the block. This collision can not only damage and render the block itself ineffective, but can also cause localized damage to the beam, such as cracking, deformation, and even fracture. Furthermore, the impact of rigid blocks can generate significant force, which can further exacerbate damage to the bridge structure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a side-mounted anti-buckling damping and anti-falling beam device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a side-mounted anti-buckling damping and anti-falling beam device, comprising a side plate and an upper plate, the side walls of the side plates being symmetrically fixedly connected to two tensile plates, the two tensile plates being distributed up and down, the two tensile plates being both L-shaped, the upper plate being T-shaped, one end of the upper plate being slidably clamped between the two tensile plates, the upper and lower surfaces of the upper plate being in contact with the two tensile plates respectively, the side plates, the tensile plates and the upper plate being cooperated to form a sliding pair, a bottom plate being provided below the upper plate, The bottom of the upper plate and the top of the bottom plate are both provided with multiple slots at equal distances, and both side walls of the upper plate and the bottom plate are installed with fixing ears, and the fixing ears on both sides of the upper plate and the fixing ears on both sides of the bottom plate are connected by steel cables, and multiple damping plates are arranged between the two steel cables, and the multiple damping plates are arranged at equal distances, and the upper and lower ends of the multiple damping plates are respectively clamped in the bottom slot of the upper plate and the top slot of the bottom plate, and the top of the bottom plate is fixedly connected to an anti-buckling part, and the anti-buckling part is located on the side of the damping plate away from the side plate, and the bottom plate is threadedly connected to multiple anchors.

[0006] Preferably, the side plates are symmetrically threaded with two groups of bolts, and the two tensile plates are located between the two groups of bolts.

[0007] Preferably, the side panels and the tensile plates are connected by integral casting, welding or bolts.

[0008] Preferably, the anti-buckling member is an anti-buckling plate fixed with reinforcing ribs, and the anti-buckling plate is located below the upper plate.

[0009] Preferably, the anti-buckling component is composed of an anti-buckling plate, a reinforcing rib, and a limiting plate. The limiting plate is provided with a limiting groove near the side wall of the upper plate. The other end of the upper plate is slidably engaged in the inside of the limiting groove. The upper plate and the limiting plate form a sliding pair.

[0010] The utility model has the following beneficial effects:

[0011] 1. The steel blocks used in this utility model tightly integrate the soft damping plates and steel cables to form a highly efficient seismic energy dissipation system. During an earthquake, the soft damping plates undergo elastic-plastic deformation, effectively dissipating the energy generated by the earthquake and thus reducing the seismic response of the bridge structure. When seismic forces exceed the design limit, the soft steel damping and steel cables work together to provide additional support and stability to the bridge, preventing the risk of beam collapse.

[0012] 2. The side panels are fixed to the sides of the beams, while the side panels are connected to the tension plates through integral casting, welding, or bolting, ensuring a connection strength no less than the maximum damping force. The lower anchors are fixed to the piers through poured concrete. This design allows the side panels, tension plates, and upper plate to form a sliding pair that accommodates longitudinal displacement of the bridge during earthquakes, thereby maintaining its overall stability. This connection method also ensures structural strength, enabling it to withstand significant damping forces.

[0013] 3. This utility model incorporates an anti-buckling member beneath the upper plate to enhance the overall stability and uniformity of the structure. The anti-buckling member effectively prevents excessive deformation on one side of the upper plate when subjected to horizontal forces, thereby ensuring uniform force distribution across the damping plate. Furthermore, the anti-buckling member ensures a stable horizontal load on the damping plate, providing a stable damping force. This design is of great significance for improving the bridge's seismic performance during earthquakes. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0018] like Figure 1 As shown, the embodiment of the utility model provides an edge-mounted anti-buckling damping anti-falling beam device, including a side plate 1 and an upper plate 3. The side wall of the side plate 1 is symmetrically fixedly connected to two tensile plates 2. The two tensile plates 2 are distributed up and down. The shapes of the two tensile plates 2 are both L-shaped. The shape of the upper plate 3 is T-shaped. One end of the upper plate 3 is slidably clamped between the two tensile plates 2. The upper and lower surfaces of the upper plate 3 are respectively in contact with the two tensile plates 2. The side plate 1, the tensile plate 2 and the upper plate 3 cooperate to form a sliding pair. A bottom plate 7 is provided below the upper plate 3. The bottom of the upper plate 3 and the bottom The top of the plate 7 is provided with multiple slots at equal intervals, and both side walls of the upper plate 3 and the bottom plate 7 are installed with fixing ears. The fixing ears on both sides of the upper plate 3 and the fixing ears on both sides of the bottom plate 7 are connected by steel cables 5. A plurality of damping plates 6 are arranged between the two steel cables 5. The plurality of damping plates 6 are arranged at equal intervals, and the upper and lower ends of the plurality of damping plates 6 are respectively clamped in the bottom slot of the upper plate 3 and the top slot of the bottom plate 7. The top of the bottom plate 7 is fixedly connected with an anti-buckling part 4, and the anti-buckling part 4 is located on the side of the damping plate 6 away from the side plate 1. The bottom plate 7 is threaded with multiple anchors 8.

[0019] The side panels 1 are symmetrically threaded with two sets of bolts, with the two tension plates 2 cleverly positioned between them. This design not only simplifies installation but also ensures a secure connection between the tension plates 2 and the side panels 1. The bolted connection allows for easy adjustment of the side panels 1 to suit different bridge structures and seismic requirements. Furthermore, the bolted connection provides sufficient strength and stability, ensuring that the tension plates 2 can effectively transmit and disperse seismic forces during an earthquake, thereby protecting the bridge structure from damage.

[0020] The connection between the side panels 1 and the tensile plates 2 can be achieved in a variety of ways, including integral casting, welding, or bolting. This design flexibility ensures that the most appropriate connection method can be selected based on actual needs in different environments. Integral casting and welding provide higher connection strength and stability, making them suitable for bridge structures with high connection requirements. Bolted connections, on the other hand, offer greater removability and flexibility, facilitating repair or replacement when needed. This diverse range of connection methods enables the present invention to be more widely applicable to different types of bridge structures.

[0021] The anti-buckling member 4 is a buckling plate with fixed reinforcing ribs, cleverly located below the upper plate 3. The presence of the reinforcing ribs not only improves the overall strength and stability of the anti-buckling plate, but also ensures a uniform stress state in the horizontal direction. By adding reinforcing ribs, the anti-buckling member 4 can more effectively resist the force applied by the upper plate 3, preventing the upper plate 3 from deforming excessively when the other side is subjected to force on one side. At the same time, the design of the anti-buckling plate also ensures that the damping plate 6 maintains a stable stress state in the horizontal direction, thereby providing a stable damping force. This optimized design is of great significance for improving the seismic performance of bridges during earthquakes. Example 2:

[0022] like Figure 2 As shown, an embodiment of the utility model provides an edge-mounted anti-buckling damping and anti-falling beam device, including an anti-buckling member 4 consisting of three parts: an anti-buckling plate, a reinforcing rib and a limit plate. Among them, a limit groove is cleverly opened on the side wall of the limit plate close to the upper plate 3, and the other end of the upper plate 3 can be slidably engaged inside the limit groove. This design not only ensures that a stable sliding pair can be formed between the upper plate 3 and the limit plate, but also improves the seismic performance of the entire structure. Through the design of sliding engagement between the limit groove and the upper plate 3, the anti-buckling member 4 can effectively limit the displacement of the upper plate 3 in the horizontal direction, avoiding the situation where the other side is excessively deformed due to unilateral force. At the same time, the presence of the reinforcing rib further enhances the overall strength and stability of the anti-buckling plate, so that the entire structure can better withstand and disperse seismic forces during an earthquake. In addition, the design of the sliding pair also enables the upper plate 3 to undergo a certain degree of longitudinal displacement during an earthquake, thereby reducing the seismic response of the bridge structure.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
