Description

Technical Field

[0001] This utility model relates to the technical field of steel structures for bridges, and in particular to a steel structure for bridges that is easy to replace. Background Technology

[0002] Steel structures for bridges refer to the steel components that bear the main load-bearing system of a bridge. Their core advantages lie in high strength, light weight, excellent toughness, and high ductility, making them particularly suitable for long-span, complex bridge structures. Because of their high strength, lightweight, rapid construction, flexible design, and reliable performance, they hold an indispensable position in modern bridges.

[0003] Existing bridge steel structures typically consist of long steel bars processed through cutting, bending, welding, drilling, riveting, and high-strength bolt connections to achieve reliable connections. However, in actual use, these steel structures are prone to localized deformation and damage due to accidental collisions or external forces over extended periods. Furthermore, the large size of the steel bars makes replacement a significant waste of resources. Therefore, this paper proposes a bridge steel structure that is easy to replace to address these issues. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a bridge steel structure that is easy to replace, including a pier 1. A bridge deck 2 is fixedly connected to the top of the pier 1. A connecting block 4 is fixedly connected to the top of the bridge deck 2. An insert 10 is slidably connected to the middle of the connecting block 4. A diagonal brace 3 is fixedly connected to the end of the insert 10. Another insert 10 is fixedly connected to the other end of the diagonal brace 3. A connecting block 5 is slidably connected to the outer periphery of the insert 10. A connecting rod 6 and a connecting rod 7 are respectively installed on the outer sides of the connecting block 6 and the connecting rod 7. Another connecting rod 6 and the connecting rod 7 are respectively installed at the other ends of the connecting rod 6 and the connecting rod 7. There is a second connecting rod 7 and another connecting rod 6. A snap-fit ​​assembly is installed between the two connecting rods 7 and the two connecting rods 6. A support assembly is installed between each of the two vertically adjacent connecting rods 6 and the two vertically adjacent connecting rods 7. The snap-fit ​​assembly includes multiple protrusions 14, which are fixedly connected to the outer sides of the connecting rods 7 and the connecting block 5. The outer sides of the connecting block 4 and the connecting rod 6 are provided with grooves 13, and the protrusions 14 are snapped into the middle of the grooves 13. The middle of the connecting block 4 and the connecting block 5 is provided with slots 15, and two inserts 10 are slidably connected to the middle of the two slots 15. First, inserting the insert 10 into the slot 15 of connecting block 4 and connecting block 5 allows the diagonal brace 3 to connect with connecting block 4 and connecting block 5. At the same time, the fixing effect is improved by the bolt 12, so that the protrusion 14 and groove 13 on the outside of connecting block 4, connecting block 5, connecting rod 6 and connecting rod 7 can be connected to each other, thus forming a whole and improving the lateral structural strength.

[0032] Reference Figures 2-4 The support assembly includes multiple support columns 8, one of which is located between two vertical connecting rods 6, another of which is located between two vertical connecting rods 7, and the third of which is located between a connecting block 5 and one of the connecting rods 7. Each of the multiple support columns 8 is fixedly connected to a fixing plate 16, and each of the fixing plates 16 is slidably connected to a bolt 17 in the middle. The bolts 17 are threadedly connected to the middle of the connecting block 5, the connecting rod 6, and the connecting rod 7, respectively. The bolts 17 pass through the connecting rod 6 and the connecting rod 7 and are threadedly connected to the middle of the bridge deck 2. Each of the fixing plates 16 has a sliding hole 18 in the middle, and the bolts 17 are slidably connected to the middle of the sliding hole 18. The vertical connecting block 2 5, connecting rod 1 6, and connecting rod 2 7 are connected by the support column 8, and the connecting rod 1 6 and connecting rod 2 7 on the surface of the bridge deck 2 are fixed to the bridge deck 2 by the action of bolt 2 17, so as to improve the longitudinal structural strength of the steel structure as a whole. At the same time, if the connecting rod 1 6 and connecting rod 2 7 are deformed and damaged in a certain area, the bolt 2 17 on the corresponding fixing plate 1 16 can be removed to facilitate the quick replacement of the connecting rod 1 6 and connecting rod 2 7 in that area, thereby reducing the cost of steel replacement.

[0033] Reference Figure 1 , Figure 2 and Figure 4 Each pair of adjacent support columns 8 is equipped with a support rod 9. A fixing plate 2 19 is fixedly connected to the outer perimeter of each support rod 9. A bolt 3 20 is slidably connected to the middle of the fixing plate 2 19. The other end of the bolt 3 20 is threaded to the middle of the adjacent support column 8. Multiple support columns 8 and multiple support rods 9 form a triangular shape. The support rods 9 are installed between adjacent support columns 8 using the fixing plate 2 19 and bolt 3 20, forming a structurally stable triangle with the support rods 9, thus further improving structural stability. Furthermore, if a support rod 9 deforms or is damaged, bolt 3 20 can be removed to allow the support rod 9 to be removed laterally for replacement.

[0034] Reference Figure 3 and Figure 4 Both connecting block 4 and connecting block 5 are slidably connected to the middle of bolt 12. The other end of one bolt 12 passes through a plug 10 and is threaded to the middle of connecting block 5. The other end of the other bolt 12 passes through connecting block 4 and plug 10 and is threaded to the middle of bridge deck 2. Both connecting block 4 and connecting block 5 have sliding holes 11 in their middle, and two bolts 12 are slidably connected to the middle of the two sliding holes 11 respectively. The plug 10 is connected to connecting block 4 and connecting block 5 by bolt 12, which improves the structural strength of vertical connecting rod 6 and connecting rod 7. At the same time, if the diagonal brace 3 is damaged, bolt 12 can be removed to pull out the diagonal brace 3. The modular diagonal brace 3, connecting block 4, connecting block 5, connecting rod 6 and connecting rod 7 facilitate the replacement of local modules, thereby reducing replacement and maintenance costs.

[0035] Working principle: First, through the modular connecting rod 6 and connecting rod 7, after the steel is partially deformed and damaged, the connecting rod 6 or connecting rod 7 can be vertically removed by disassembling the bolt 17 on the corresponding support 8 outer peripheral fixing plate 16. This allows for the disassembly and replacement of the partially damaged connecting rod 6 and connecting rod 7, thereby reducing replacement and maintenance costs.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
