It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0031] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0032] like Figure 1 As shown, this utility model embodiment proposes a wire rope bridge structure, including: a first wire rope assembly 10, including multiple first wire ropes 11 arranged along its axial direction, each of the first wire ropes 11 being tightened and fixed to anchor points on both banks; a first steel plate assembly 20, including multiple first steel plates 21, the multiple first steel plates 21 being laid in an array on the first wire rope assembly 10; a second steel plate assembly 30, including multiple second steel plates 31, the multiple second steel plates 31 being laid in an array on the first steel plate assembly 20; a second wire rope assembly 40, both ends being tightened and fixed to anchor points on both banks, and the second steel plate assembly 30 being connected to the bottom by multiple square steels 60; and a third steel plate assembly, including multiple third steel plates, the multiple third steel plates being laid in an array on the second wire rope assembly (40).

[0033] In this embodiment, suitable anchorage points are first selected on both banks of the bridge, and multiple first steel wire ropes 11 are tightened and fixed to form a preliminary load-bearing structure. These first steel wire ropes 11 are arranged axially to provide stable bridge deck foundation support. Then, a first steel plate assembly 20 is laid, and multiple first steel plates 21 are laid on the first steel wire rope assembly 10 and arranged in an array. These first steel plates 21 can be stabilized by their own weight and interlocking, while further distributing the load evenly and enhancing the load-bearing capacity. Next, a second steel plate assembly 30 is laid, and multiple second steel plates 31 are laid on the first steel plate assembly 20 to further enhance the stability and rigidity of the bridge deck. The second steel plates 31 can be connected by threaded rods or welding to improve the overall shear and deformation resistance. Subsequently, the second steel wire ropes are fixed at the anchorage points on both banks of the bridge and maintained with appropriate tension. Multiple square steel bars 60 are arranged below the second steel wire rope assembly 40 and connected to the second steel plate assembly 30 to form additional structural support, improving the overall stability and seismic resistance of the bridge. Then, a third steel plate assembly 50 is laid, and multiple third steel plates 51 are laid on the second steel wire rope assembly 40 and arranged in an array. Finally, a concrete layer is laid to form the final bridge deck, improving driving comfort and durability.

[0034] In one embodiment, the adjacent first steel plates 21 are interlocked, forming a unified load-bearing structure. This prevents uneven stress or displacement of individual plates, improving the overall rigidity and stability of the bridge deck and preventing localized warping or misalignment under load, thus ensuring driving safety. Furthermore, the interlocking connection allows for rapid on-site assembly without welding or additional fixing, significantly reducing construction time. No additional fasteners (such as bolts or welding materials) are required during construction, reducing installation difficulty.

[0035] Specifically, the first steel plate 21 has a groove on each of its front and back sides so that they can be interlocked and connected to each other, making the bridge laying process faster. The first steel plate 21 is 5cm thick, 2cm wide, and 10cm long.

[0036] In one embodiment, the two ends of the first steel plate assembly 20 are tensioned and fixed to anchor points on both banks by ropes. Since the first steel plate assembly 20 is laid on the first steel wire rope 11, without fixation, the first steel plate assembly 20 may be misaligned or slipped due to factors such as vehicle running over it or wind force, affecting driving safety. After tensioning and fixing, the first steel plate assembly 20 is controlled in both axial and lateral directions, and will not loosen or shift. Furthermore, after the adjacent first steel plates 21 are fastened together, the end tensioning and fixing can enhance the fastening stability and prevent the connection from loosening after long-term use.

[0037] In one embodiment, the lengths of the plurality of square steel bars 60 can be the same or different. When all square steel bars 60 are of the same length, the second wire rope assembly 40 is in a horizontal state, resulting in more uniform stress distribution, providing stable support, and improving the overall strength of the bridge. Furthermore, square steel bars of the same specification facilitate standardized production and on-site assembly, making construction more efficient and suitable for rapid construction needs. Especially for motor vehicles or heavy transport vehicles, a horizontal bridge deck reduces bumps and improves driving safety and comfort. If the lengths of the square steel bars 60 vary according to a certain pattern, causing the second wire rope assembly 40 to form a micro-arch, then the bridge structure resembles an arch bridge, which can more effectively distribute the load and improve the overall load-bearing capacity. Moreover, the arched structure has less deflection under load than a horizontal structure, reducing bridge deck deformation, improving driving stability, and enhancing wind resistance.

[0038] Secondly, the arched design allows rainwater to flow naturally to both sides, reducing water accumulation and preventing damage to the bridge deck due to long-term water accumulation, making it particularly suitable for areas with high rainfall. For example, when crossing different terrains (such as rivers and valleys), the arched design can better distribute the stress points of the bridge, reduce the requirements for the foundation, and make the bridge more adaptable to complex terrain.

[0039] In another embodiment, longer square steel bars 60 can be used in the central area of ​​the bridge to form a micro-arch, while square steel bars of the same length can be used in the two side areas, making the bridge deck more stable while also ensuring load-bearing capacity. This is suitable for bridges with long spans and can effectively balance stress optimization and construction convenience.

[0040] In one embodiment, multiple railings 70 are provided on both sides of the first steel plate assembly 20. These railings 70 connect to both sides of the second steel plate assembly 30. Specifically, the multiple railings 70 are connected to both sides of the second steel plate assembly 30 via threaded steel bars 80. As a protective facility for the bridge, the railings 70 effectively prevent pedestrians and vehicles from falling due to loss of control or environmental factors (such as strong winds, rain, or snow), improving traffic safety. Furthermore, the railings 70 are not only protective structures but also limit the lateral sway of the bridge deck to a certain extent, especially in strong winds or earthquake environments, improving the bridge's resistance to lateral forces. The threaded steel bars 80 have high tensile strength, firmly fixing the railings 70 and preventing loosening or breakage due to long-term use or external forces (such as impacts). After the railings 70 are connected to the second steel plate assembly 30 via the threaded steel bars 80, they form an integral frame with the bridge deck, improving the overall rigidity of the bridge and making it more stable under stress, reducing sway.

[0041] Secondly, the rebar 80 itself has good ductility, which allows it to absorb some energy during earthquakes or strong winds, reducing damage to the railing 70 and improving the bridge's seismic performance. Furthermore, when vehicles or pedestrians collide, the railing 70 connected by the rebar 80 can effectively absorb the impact force, reducing damage to the bridge structure and lowering the risk of accidents.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
