[0008] The utility model has the following beneficial effects:

[0009] 1.

When encountering extremely strong earthquake forces that exceed the design limits of the steel damping plates, the steel cables serve as a second line of defense, working in conjunction with the steel damping plates to provide additional support and stability. This dual protection mechanism greatly reduces the risk of bridge beam collapse.

[0010] 2. The sliding pair composed of SF-1 sliding plate and mirror stainless steel not only ensures the smooth longitudinal displacement of the bridge during an earthquake and reduces the direct impact caused by seismic waves, but also effectively buffers and evenly transmits the impact force during the displacement process through the buffer pad between the side embedded steel plate assembly and the holding plate, thus protecting the integrity of the bridge structure.

[0011] 3. Connecting the armrest and base plates with steel cables not only simplifies the structure but also ensures that the multi-layer steel damping plates evenly distribute the load, preventing damage caused by excessive localized stress. This design is more in line with mechanical principles and improves the overall stability and reliability of the anti-fall beam device.

[0012] 4. The anchoring system, which utilizes bolts and embedded components, makes the entire anti-fall beam system extremely convenient to assemble, disassemble, and replace. After an earthquake, any necessary replacement or repair can be carried out quickly without affecting the normal operation of the bridge. Furthermore, the side-mounted design provides ample space for inspection and maintenance, reducing operational complexity and costs. 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 1-2 As shown, the embodiment of the utility model provides a side-mounted damping anti-falling beam device, including a holding plate 1 and a steel cable 4, a side wall of the holding plate 1 is provided with a buffer pad 10, and the buffer pad 10 is installed with a side embedded steel plate assembly 6 away from the side wall of the holding plate 1, the holding plate 1, the side embedded steel plate assembly 6, and the buffer pad 10 are fixedly connected by bolts, the shape of the holding plate 1 is T-shaped, the holding plate 1 is composed of a horizontal plate and a vertical plate, the end of the horizontal plate of the holding plate 1 away from the side embedded steel plate assembly 6 is U-shaped, the bottom of the horizontal plate of the holding plate 1 is provided with an upper plate 2, and the side wall of the vertical plate of the holding plate 1 away from the buffer pad 10 is fixedly connected with a fixed plate, the fixed plate of the holding plate 1 is located below the horizontal plate of the holding plate 1, the connection between the fixed plate of the holding plate 1 and the vertical plate of the holding plate 1, the horizontal plate of the holding plate 1 away from the side embedded An SF-1 slide plate 8 is provided at the bending part of one end of the steel plate assembly 6. The shape of the SF-1 slide plate 8 is L-shaped. The two side walls of the upper plate 2 and the lower surface of the two ends of the upper plate 2 are provided with mirror stainless steel 9. The mirror stainless steel 9 is in sliding contact with the SF-1 slide plate 8. A bottom plate 5 is provided under the upper plate 2. The two side walls of the upper plate 2 and the two side walls of the bottom plate 5 are provided with ear plates. The two side ear plates of the upper plate 2 and the two side ear plates of the bottom plate 5 are respectively connected by two steel cables 4. A plurality of steel damping plates 3 are provided between the two steel cables 4. The bottom of the upper plate 2 and the top of the bottom plate 5 are equidistantly provided with slots. The upper and lower ends of the plurality of steel damping plates 3 are respectively clamped in the slots of the upper plate 2 and the slots of the bottom plate 5. The bottom plate 5 is threaded with a plurality of anchors 7.

[0019] The rectangular arrangement of anchors 7 ensures uniform support and fixation of the steel damping plate 3 in multiple directions, preventing localized damage caused by excessive force at a single point. This rectangular arrangement also clarifies the installation location of anchors 7, facilitating quick and accurate installation by construction personnel. Whether on a flat bridge deck or a curved structure, the rectangular arrangement of anchors 7 provides stable support, ensuring the effective operation of the steel damping plate 3.

[0020] The rectangular shape of the steel damping plate 3 not only facilitates processing and installation but also provides a stable support surface when stacked in multiple layers, reducing the risk of interlayer slippage. The circular grooves running through the sidewalls provide space for elastic-plastic deformation of the steel damping plate 3, preventing damage caused by stress concentration. The combination of the rectangular shape and the circular grooves in the sidewalls allows the steel damping plate 3 to deform more effectively under external forces such as earthquakes, thereby dissipating more seismic energy and reducing the seismic response of the bridge structure.

[0021] Working Principle: When using a side-mounted damping and anti-falling beam device, a side embedded steel plate assembly 6 is pre-embedded in the bridge pier or designated location, ensuring a secure connection to the bridge structure. This side embedded steel plate assembly 6 is bonded to the side of the beam, providing a foundation for subsequent device installation. The upper plate 2 is installed so that the mirror-finished stainless steel plate 9 on the upper plate 2 contacts the SF-1 slide plate 8 on the arm plate 1. The sliding pair formed by the SF-1 slide plate 8 and the mirror-finished stainless steel plate 9 ensures smooth and binding-free installation. A cushion 10 between the side embedded steel plate assembly 6 and the arm plate 1 provides cushioning and uniform force transmission. The mild steel damping plate 3 is installed in the designated location, ensuring a secure connection to the upper plate 2 and base plate 5. Steel cables 4 connect the arm plate 1 and base plate 5 to form a stable support structure. The tension of the cables 4 is adjusted to ensure uniform deformation of the damping element under load and effectively dissipate seismic energy. During an earthquake, the elastic-plastic deformation of the mild steel damping plate 3 effectively dissipates seismic energy and significantly reduces the seismic response of the bridge structure. When encountering extremely strong earthquake forces that exceed the design limit of the steel damping plate 3, the steel cables 4 act as a second line of defense, working in conjunction with the steel damping plate 3 to provide additional support and stability. The dual protection mechanism greatly reduces the risk of bridge beams falling. Example 2:

[0022] The steel damping plate 3 is rectangular in shape, with arcuate grooves defined on its front and rear surfaces. A circular groove runs through its sidewalls, with the circular groove located between the two arcuate grooves. The rectangular shape of the steel damping plate 3 is chosen because it provides excellent structural stability and ease of fabrication and installation in bridge beam-fall prevention systems. This rectangular shape ensures that seismic forces acting on the steel damping plate 3 are evenly distributed across its entire surface, thereby enhancing its seismic performance. The arcuate grooves defined on the front and rear surfaces of the steel damping plate 3 are primarily intended to enhance its elastic-plastic deformation capacity. These arcuate grooves allow the steel damping plate 3 to bend and deform more significantly in these areas when subjected to seismic forces, thereby dissipating more seismic energy. Furthermore, the arcuate grooves guide stress distribution, ensuring more uniform deformation of the steel damping plate 3 and preventing damage caused by localized stress concentrations. The side walls of the steel damping plate 3 are provided with circular grooves, and these circular grooves are located between the two arc-shaped grooves. The provision of the circular grooves can reduce the overall weight of the steel damping plate 3, making the device more flexible during an earthquake and more likely to deform in response to the displacement of the bridge. The presence of the circular grooves further enhances the elastic-plastic deformation capacity of the steel damping plate 3. Under the action of seismic forces, the material around the circular grooves is more likely to deform, thereby consuming more seismic energy. The circular grooves and the arc-shaped grooves cooperate with each other to further optimize the stress distribution of the steel damping plate 3 when subjected to stress.

[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.
