[0002] In modern cities, both banks of a river are developed, and a riverside walkway is built on both banks of the river for citizens to keep fit and enjoy the river view. A connecting bridge is provided on both banks of the river, and thus the bridge needs to meet the needs of residents for the pedestrian and sightseeing functions of the bridge.

[0003] In general municipal projects, there is a certain height difference between a riverside road and a river-crossing bridge deck, and the pedestrian system on the bridge and the pedestrian system on the riverside road are connected through detouring. In this scheme, the pedestrian passage detours far, and the fast and slow traffic systems are not connected smoothly. In another scheme, the pedestrian systems are connected through a vertical elevator. This scheme has high construction and maintenance costs, and the vertical elevator blocks the view of the outer facade of the bridge, affecting the bridge landscape.

[0004] Therefore, in view of the above, the existing structure and deficiencies are improved, and a new bridge structure system is provided, so as to achieve a more practical purpose. SUMMARY

[0011] In some embodiments, the main suspender is arranged at intervals along the longitudinal direction of the beam bridge, the top end of the main suspender is connected to the center line of the arch rib, and the bottom end is connected to the center line of the beam bridge.

[0012] In some embodiments, a secondary suspender is uniformly distributed between the pedestrian arch bridge and the beam bridge.

[0013] In some embodiments, the auxiliary suspender is arranged along the center line direction of the pedestrian arch bridge and distributed on both sides of the center line of the pedestrian arch bridge.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a double-layer arch-beam composite structure system that can solve the problems mentioned in the background art.

[0029] See Figure 1 and Figure 2 As shown, this application embodiment provides a double-layer arch-beam composite structural system, including:

[0030] The beam bridge 1 has an arch rib 2 spanning both banks and located upstream and downstream of the beam bridge 1. Main hangers 3 are evenly distributed between the arch rib 2 and the beam bridge 1.

[0031] Pedestrian arch bridge 4 is located below beam bridge 1 and spans both banks. Pedestrian arch bridge 4 and arch rib 2 are intersected in the horizontal projection direction.

[0032] Pedestrian walkway 5 is set on both banks and connects the ends of arch rib 2 and pedestrian arch bridge 4 respectively. Both ends of arch rib 2 are provided with stairways 6 connecting pedestrian walkway 5 and beam bridge 1.

[0033] The double-layer arch-beam composite structure system of this application embodiment includes a beam bridge 1, a pedestrian arch bridge 4, and a pedestrian walkway 5. An arch rib 2 is provided above the beam bridge 1, spanning both banks and located upstream and downstream of the beam bridge 1. Main hangers 3 are evenly distributed between the arch rib 2 and the beam bridge 1. The main hangers 3 can bear vertical loads, improve the stability of the beam bridge 1, and at the same time, facilitate the construction of stairways 6 at both ends of the beam bridge 1 to connect the pedestrian walkways 9 on both sides of the beam bridge 1.

[0034] In addition, the pedestrian arch bridge 4 is located below the beam bridge 1 and spans both banks. The pedestrian arch bridge 4 and the arch rib 2 are intersected in the horizontal projection direction, which ensures the distance between the ends of the pedestrian arch bridge 4 and the ends of the arch rib 2, optimizes the spatial layout, reduces the construction difficulty, and at the same time, creates a sense of layering in the space, enhancing the aesthetics of the entire structural system.

[0035] Finally, pedestrian walkways 5 are set up on both sides of the river. The pedestrian walkways 5 connect the ends of the arch rib 2 and the pedestrian arch bridge 4 respectively, so as to connect the pedestrian system on the beam bridge 1 with the pedestrian system of the riverside road on both sides by using the step stairs 6 on the arch rib 2, the pedestrian arch bridge 4, and the pedestrian walkways 5, which greatly improves the efficiency of the pedestrian system.

[0036] Specifically, pedestrians on the beam bridge 1 can reach the pedestrian boardwalk 5 and the riverside road on the bank via the staircase 6 on the arch rib 2, or they can reach the pedestrian boardwalk 5 and the riverside road on the opposite bank via the pedestrian arch bridge 4. Similarly, pedestrians on the riverside roads on both banks can reach either side of the beam bridge 1 via the pedestrian boardwalk 5, the pedestrian arch bridge 4, and the staircase 6.

[0037] The above structure not only achieves efficient connection between the riverside pedestrian system and the upper-level pedestrian system of beam bridge 1, but also allows pedestrian arch bridge 4 and pedestrian boardwalk 5 to serve as waterfront platforms for pedestrians, meeting people's needs for leisure and entertainment by the river, thereby further enhancing their practical value.

[0038] It should be noted that the double-layer arch beam composite structure system of this application can be applied not only to riverbanks but also to valleys and other terrains, and can also improve the efficiency of pedestrian systems.

[0039] Furthermore, this application does not impose specific requirements or special limitations on the type and specifications of the beam bridge 1. The function of the beam bridge 1 in this application is to meet the needs of upper-level vehicle and pedestrian traffic. The beam bridge 1 can be a continuous beam bridge, but is not limited to continuous beam bridges. It can also be other types of bridges. Therefore, it is understood that other beam bridges 1 that can achieve this function can be used in this application. Those skilled in the art can make adaptive adjustments to the type and specifications of the beam bridge 1 according to the usage scenario and test conditions.

[0040] In some alternative embodiments: see Figure 1 and Figure 2As shown, this application embodiment provides a double-layer arch beam composite structure system. The double-layer arch beam composite structure system has piers 11 for supporting the beam bridge 1 below the beam bridge 1. The piers 11 are arranged at both ends of the beam bridge 1, and the main hanger 3 is arranged between the piers 11 at both ends.

[0041] In this embodiment of the application, the double-layer arch-beam composite structure system has a beam bridge 1 spanning both banks. The piers 11 are used to support the beam bridge 1 to ensure its stability. Furthermore, the main hangers 3 are connected between the arch ribs 2 and the beam bridge 1, and the piers 11 are distributed along the longitudinal direction of the beam bridge 1 on both sides of the main hangers 3.

[0042] Since the main hanger 3 can bear vertical loads, the area where the main hanger 3 is arranged does not need to be supported by piers 11 to support the beam bridge 1, which optimizes the stress on the beam bridge 1, reduces the number of piers 11, and is suitable for geological conditions with poor foundation bearing capacity. In addition, it can ensure that pedestrians on the pedestrian arch bridge 4 below the beam bridge 1 have a wide field of vision and are not affected by the piers 11.

[0043] In some alternative embodiments: see Figure 1 and Figure 2 As shown, this application embodiment provides a double-layer arch beam composite structure system. The main hangers 3 of the double-layer arch beam composite structure system are arranged at intervals along the longitudinal direction of the beam bridge 1. The top end of the main hanger 3 is connected to the centerline of the arch rib 2, and the bottom end is connected to the centerline of the beam bridge 1.

[0044] The main hangers 3 of the double-layer arch-beam composite structure system of this application embodiment are arranged at intervals along the longitudinal direction of the beam bridge 1. Furthermore, the top end of the main hanger 3 is connected to the centerline of the arch rib 2 and the bottom end is connected to the centerline of the beam bridge 1, so that the arch rib 2 can stably transfer part of the self-weight of the beam bridge 1 and the load it bears to the ground, thereby ensuring the stability of the beam bridge 1 during the implementation of this structural system.

[0045] In some alternative embodiments: see Figure 1 and Figure 2 As shown, this application embodiment provides a double-layer arch-beam composite structure system, in which auxiliary hangers 7 are evenly distributed between the pedestrian arch bridge 4 and the beam bridge 1.

[0046] In this embodiment of the application, the pedestrian arch bridge 4 and the beam bridge 1 of the double-layer arch-beam composite structure system are evenly distributed with auxiliary hangers 7. Since the auxiliary hangers 7 can bear vertical loads, the stress situation of the pedestrian arch bridge 4 can be improved and the stability of the pedestrian arch bridge 4 can be enhanced.

[0047] Specifically, the vertical load of the pedestrian arch bridge 4 can be transferred to the arch rib 2 via the secondary hanger 7 through the beam bridge 1 and the main hanger 3. The arch rib 2 bears most of the vertical load of the beam bridge 1 and the pedestrian arch bridge 4, which reduces the horizontal thrust at the arch foot of the pedestrian arch bridge 4, optimizes the stress structure of the pedestrian arch bridge 4, reduces the requirements of the foundation bearing capacity of the pedestrian arch bridge 4, and is suitable for geology with poor foundation bearing capacity.

[0048] For example, the main hanger 3 and the auxiliary hanger 7 in the embodiments of this application can be made of solid steel bars. The solid steel bars are inclined and fixed at both ends by anchoring. The function of the main hanger 3 and the auxiliary hanger 7 in this application is to transfer the vertical load of the beam bridge 1 and the pedestrian arch bridge 4 to the arch rib 2. Therefore, it is understood that those skilled in the art can make adaptive adjustments to the size, shape and material of the main hanger 3 and the auxiliary hanger 7 according to the usage scenario and test conditions.

[0049] In some alternative embodiments: see Figure 1 and Figure 2 As shown, this application embodiment provides a double-layer arch beam composite structure system. The auxiliary hangers 7 of the double-layer arch beam composite structure system are arranged at intervals along the centerline of the pedestrian arch bridge 4 and distributed on both sides of the centerline of the pedestrian arch bridge 4.

[0050] In this embodiment of the double-layer arch-beam composite structure system, the auxiliary hangers 7 are spaced apart along the centerline of the pedestrian arch bridge 4. Furthermore, the auxiliary hangers 7 are distributed on both sides of the centerline of the pedestrian arch bridge 4, with the middle for pedestrians to walk on. The structural arrangement is reasonable and does not affect the pedestrian passage on the pedestrian arch bridge 4. At the same time, since the pedestrian arch bridge 4 has a certain width, the auxiliary hangers 7 are spaced apart on both sides of the centerline of the pedestrian arch bridge 4, which can stably transfer the load to the beam bridge 1 and ensure the overall structural stability.

[0051] In some alternative embodiments: see Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a double-layer arch beam composite structure system. The beam bridge 1 of the double-layer arch beam composite structure system is provided with main piers 21 for supporting the ends of the arch ribs 2 at its upstream and downstream. The main piers 21 are connected to the pedestrian walkway 5.

[0052] In this embodiment of the double-layer arch-beam composite structure, the beam bridge 1 is provided with main piers 21 at its upstream and downstream. The main piers 21 are used to support the ends of the arch ribs 2 and can also serve as a platform connecting the pedestrian walkway 5 and the stairway 6, ensuring the safety and smooth passage of pedestrians. Furthermore, the water level of the main piers 21 is slightly higher than the water level line, which can ensure a better water view effect.

[0053] In some alternative embodiments: see Figure 1 and Figure 2As shown in the figure, this application embodiment provides a double-layer arch beam composite structure system. The beam bridge 1 of the double-layer arch beam composite structure system is provided with a secondary pier 41 for supporting the end of the pedestrian arch bridge 4. The secondary pier 41 is connected to the pedestrian walkway 5.

[0054] In this embodiment of the double-layer arch-beam composite structure system, a secondary pier 41 is provided below the beam bridge 1. The secondary pier 41 is used to support the end of the pedestrian arch bridge 4 and can also serve as a platform connecting the pedestrian walkway 5 and the stairway 6, ensuring the safety and smooth passage of pedestrians. Furthermore, the water level of the secondary pier 41 is slightly higher than the water level line, which can ensure a better water view effect.

[0055] In some alternative embodiments: see Figure 1 and Figure 2 As shown in the embodiment of this application, a double-layer arch beam composite structure system is provided. The pedestrian walkway 5 of the double-layer arch beam composite structure system is ribbon-shaped and is centrally symmetrically distributed.

[0056] In this embodiment of the application, the pedestrian walkway 5 of the double-layer arch beam composite structure system is ribbon-shaped. Furthermore, the pedestrian walkways 5 on both banks are centrally symmetrically distributed. The pedestrian walkways 5 serve as viewing platforms along the riverbank. From an overhead view, the pedestrian walkways 5 on both sides, together with the arch ribs 2 and the pedestrian arch bridge 4, form an "∞" shape. The beam bridge 1 is inserted through it, perfectly connecting the pedestrian system on the bridge and the pedestrian system on the riverside road, realizing the cyclical integration between the bridge and the arch, and enhancing the overall aesthetics of the double-layer arch beam composite structure system.

[0057] In some alternative embodiments: see Figure 1 and Figure 2 As shown in the embodiment of this application, a double-layer arch-beam composite structure system is provided, wherein the rise-to-span ratio of the arch rib 2 in the double-layer arch-beam composite structure system is greater than that of the pedestrian arch bridge 4.

[0058] In this embodiment of the double-layer arch-beam composite structure system, the rise-to-span ratio of the arch rib 2 is greater than that of the pedestrian arch bridge 4, which can reduce the horizontal thrust at the arch foot of the arch rib 2, optimize the structural stress, that is, improve the stress condition of the arch rib 2, and enhance the overall stability.

[0059] Specifically, the vertical load of the pedestrian arch bridge 4 can be transferred to the arch rib 2 via the auxiliary hanger 7 through the beam bridge 1 and the main hanger 3. The arch rib 2 bears most of the vertical load of the beam bridge 1 and the pedestrian arch bridge 4, thus reducing the horizontal thrust at the arch foot of the pedestrian arch bridge 4. At the same time, because the rise-to-span ratio of the arch rib 2 is relatively large, the horizontal thrust at the arch foot of the arch rib 2 is also very small. In summary, this structural system has a reasonable stress distribution and is suitable for geological conditions with poor foundation bearing capacity.

[0060] In some alternative embodiments: see Figure 1 and Figure 2As shown in the embodiment of this application, a double-layer arch beam composite structure system is provided. The beam bridge 1 of the double-layer arch beam composite structure system is provided with a carriageway 8 extending along the length direction of the beam bridge 1, and a sidewalk 9 located on both sides of the carriageway 8 and connected to the stairway 6.

[0061] The double-layer arch-beam composite structure system of this application has a carriageway 8 extending along the length of the beam bridge 1, and a pedestrian walkway 9 located on both sides of the carriageway 8 and connected to the stairway 6. By utilizing the stairway 6 of the arch rib 2, the pedestrian arch bridge 4, and the pedestrian boardwalk 5, the pedestrian walkway 9 on the beam bridge 1 is connected to the walkways on both sides of the river, which greatly improves the efficiency of the pedestrian system.

[0062] In addition, the double-layer arch-beam composite structure system of this application can transfer the load of the beam bridge 1 and the pedestrian arch bridge 4 to the arch rib 2 through the main hanger 3 and the auxiliary hanger 7. The high rise-to-span ratio of the arch rib 2 can transfer the load to the foundation more efficiently, thereby improving the overall stability.
