Description

Technical Field

[0001] This application relates to the field of bridge engineering, specifically to a bridge with a viewing platform. Background Technology

[0002] With economic development, people have increasingly higher demands for urban leisure walkways and sightseeing platforms. In urban bridges, pedestrian walkways are often narrow. During major holidays, large light shows, and events, the width of these walkways often cannot meet the needs of the large number of visitors. Therefore, sightseeing platforms are commonly installed on urban bridges to allow citizens to enjoy the scenery. These platforms also serve as landmarks, enhancing the regional landscape. Furthermore, when the main piers are high, the platforms can even be used for recreational activities such as bungee jumping.

[0003] In related technologies, due to considerations of bridge construction costs, sightseeing platforms are usually set directly on the cantilever structure of the main beam of the bridge, without setting up separate piers for the sightseeing platforms. However, due to the limitations of the cantilever length and bearing capacity of the main beam, the size of the sightseeing platform is usually set to be small, which makes it difficult to meet the sightseeing needs when there are many tourists. Summary of the Invention

[0004] This application provides a bridge with a sightseeing platform, which can solve the technical problem in related technologies where the sightseeing platform is directly set on the cantilever structure of the main beam of the bridge. Due to the limitations of the cantilever length and bearing capacity of the main beam, the size of the sightseeing platform is usually set to be small, making it difficult to meet the sightseeing needs when there are many tourists.

[0006] In conjunction with the first aspect, in one embodiment, the pier body and the support are connected by a first prestressed member. The pier body is provided with a first tensioning point on the side away from the beam body along the transverse direction of the bridge. The support is provided with a second tensioning point. The two ends of the first prestressed member are respectively fixed to the first tensioning point and the second tensioning point. The first prestressed member extends in the horizontal direction.

[0007] In conjunction with the first aspect, in one embodiment, the top of the pier body is provided with a third tensioning point, and the pier body is also provided with an anchoring point. The anchoring point and the support are on the same horizontal plane. The anchoring point and the third tensioning point are connected by a second prestressing member, which is perpendicular to the first prestressing member.

[0008] In conjunction with the first aspect, in one embodiment, the pier body includes a main pier and a support pier integrally connected to the top surface of the main pier. An expansion joint is provided between the support pier and the beam body along the transverse direction of the bridge. The top surface of the support pier extends integrally to the side away from the beam body to form the platform panel.

[0009] In conjunction with the first aspect, in one embodiment, the sightseeing area is provided with a pedestrian section and a non-motorized vehicle section, the pedestrian section and the non-motorized vehicle section are arranged along the transverse direction of the bridge, and the non-motorized vehicle section is located on the side of the pedestrian section closer to the beam.

[0010] In conjunction with the first aspect, in one embodiment, the pedestrian section includes a viewing platform, the top surface of which is higher than the top surface of the platform panel, and steps are provided on three sides of the viewing platform, with a guardrail provided on the side of the top surface of the viewing platform closest to the beam.

[0011] In conjunction with the first aspect, in one embodiment, a portion of the viewing platform is located on the top surface of the platform panel, and another portion is located on the top surface of the supporting pier, and the portion of the viewing platform located on the platform panel is a hollow structure.

[0012] In conjunction with the first aspect, in one embodiment, the supporting pier is a solid structure, and the edges of the cross-section of the supporting pier along the horizontal direction coincide with the side of the main pier.

[0013] In conjunction with the first aspect, in one embodiment, the side of the platform panel away from the beam has a box-shaped cross-section, and the side of the platform panel closer to the beam has a solid cross-section.

[0014] In conjunction with the first aspect, in one embodiment, both the triangular stiffener and the platform panel are made of metal.

[0015] The beneficial effects of the technical solutions provided in this application include:

[0016] By designing piers with grooves and placing the beams within these grooves, the sightseeing area can be built on the piers and a platform panel protruding from the top surface of the piers. The area for people to move around on the bridge is no longer limited to the sightseeing area; the platform panel can also serve as an activity area. Furthermore, the sightseeing area is higher than the platform panel, allowing people to play at higher elevations and enhance the entertainment atmosphere. When people move around in the sightseeing area and on the platform panel, the pressure exerted on the piers is applied. Because the piers have strong load-bearing capacity, the width of the platform panel along the transverse direction can be set greater than the width of the cantilever along the transverse direction, while still meeting the pier's own load-bearing capacity requirements. This increases the space for people to move around. Additionally, triangular stiffeners are installed between the platform panel and the piers, thus strengthening the load-bearing capacity of the platform panel while ensuring the piers meet their load-bearing requirements. This solves the technical problem in related technologies where, when placing a sightseeing platform on the cantilever structure of the main bridge beam, the size of the platform is usually small, making it difficult to meet the sightseeing needs when there are many visitors.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0033] This application provides a bridge with a sightseeing platform, which solves the technical problem in related technologies where the sightseeing platform is directly placed on the cantilever structure of the main beam of the bridge. Due to the limitations of the cantilever length and bearing capacity of the main beam, the size of the sightseeing platform is usually small, making it difficult to meet the sightseeing needs when there are many tourists.

[0034] See Figure 1The diagram shows a bridge with a viewing platform according to an embodiment of this application. It includes: a pier 1, the top surface of which has a groove 11; the top of the pier 1 protrudes transversely towards the side away from the groove 11 to form a platform panel 13; both the top surface of the platform panel 13 and the top surface of the pier 1 have viewing areas 5 where people can stand and engage in recreational activities; a beam 2, also called a main beam, which is located within the groove 11 and connected to the pier 1 via supports 3; a cantilever 21 on one side of the beam 2, which protrudes along the opening of one side of the groove 11 towards the side away from the platform panel 13; and the top surface of the beam 2 is flush with the top surface of the platform panel 13. The platform panel 13 is flat, and its width along the transverse direction is greater than that of the cantilever 21. In this case, the platform panel 13 can extend directly from the pier 1 to one side as a space for people to move around. Compared with the previous placement of the sightseeing platform on the cantilever 21 of the main beam, the pier 1, as the support of the platform panel 13, has a stronger load-bearing capacity. Therefore, the length of the platform panel 13 along the transverse direction can be set to be greater than the length of the cantilever 21 of the beam 2 along the transverse direction, so that there is more space for movement on the platform panel 13. The first side of the triangular stiffener 4 is fixed to the bottom surface of the platform panel 13, and the second side is fixed to the side of the pier 1. There can be one or more triangular stiffeners 4, and their number is determined according to the force on the platform panel 13.

[0035] This embodiment of the application, by setting a pier 1 with a groove 11 and placing the beam 2 in the groove 11, allows the sightseeing area 5 to be built on the pier 1 and the platform panel 13 protruding from the top surface of the pier 1. The range of activity for people on the bridge is no longer limited to the sightseeing area 5; the platform panel 13 can also serve as an activity area. The sightseeing area 5 is also higher than the platform panel 13, allowing people to play at a higher level to enhance the entertainment atmosphere. Furthermore, the sightseeing area 5 utilizes the longitudinal space on the platform panel 13, increasing the activity area within the limited bridge area and enhancing the comfort of visitors. When people move around in the sightseeing area 5 and on the platform panel 13, the pressure they experience will act on the pier 1. Because the pier 1 has a strong bearing capacity, the platform panel 13 can be constructed while meeting the bearing capacity requirements of the pier 1. The width of the platform panel 13 along the transverse direction of the bridge is set to be greater than the width of the cantilever 21 along the transverse direction of the bridge to increase the activity space for people. Triangular stiffeners 4 are provided between the platform panel 13 and the pier 1. Therefore, while the pier 1 meets the bearing capacity requirements, the bearing capacity of the platform panel 13 is also strengthened. The triangular stiffeners 4 can directly transfer the load of the platform panel 13 to the pier 1. By increasing the number of triangular stiffeners 4, the stiffness of the platform panel 13 can be increased, thereby meeting the strength requirements of the platform panel 13 and the comfort requirements for pedestrian passage. The triangular stiffeners 4 can adopt rectangular cross sections, channel cross sections, etc. The above-mentioned arrangement solves the technical problem in related technologies where the size of the sightseeing platform is usually set small when the sightseeing platform is set on the cantilever 21 structure of the main beam of the bridge, making it difficult to meet the sightseeing needs when there are many sightseeers.

[0036] In some optional embodiments, the pier 1 and the support 3 are connected by a first prestressed member. The pier 1 has a first tensioning point on the side away from the beam 2 along the transverse direction of the bridge, and the support 3 has a second tensioning point. The two ends of the first prestressed member are fixed to the first tensioning point and the second tensioning point, respectively. The first prestressed member extends in the horizontal direction. Since the platform panel 13 protrudes from the top surface of the pier 1 toward the side away from the groove 11 (i.e. away from the beam 2), the platform panel 13, which is in a suspended state, will generate a large transverse bending moment on the pier 1. Therefore, a first prestressed member is set between the pier 1 and the support 3 of the beam 2 to form a prestressed tensioning device. By pre-tensioning the prestressed tensioning device, the transverse bending moment value can be pre-balanced, so that the pier 1 can avoid excessive tensile stress on one side as much as possible, thereby increasing the safety of the platform panel 13. The first prestressed member can be made of materials such as steel strand, high-strength steel wire, and precision-rolled threaded steel bars.

[0037] See Figure 3As shown, in some optional embodiments, the top of the pier body 1 is provided with a third tensioning point 61, and the pier body 1 is also provided with an anchoring point 62. The anchoring point 62 and the support 3 are on the same horizontal plane. The anchoring point 62 and the third tensioning point 61 are connected by a second prestressing member 63. The second prestressing member 63 is perpendicular to the first prestressing member. Under the action of the third tensioning point 61, the anchoring point 62, and the second prestressing member 63, a prestressed tensioning device can also be formed. At this time, the second prestressing member 63 is perpendicular to the first prestressing member. That is, the second prestressed member 63 can be in a vertical state. Preferably, the second prestressed member 63 is located on the side of the pier body 1 near the groove 11. At this time, the side of the pier body 1 near the groove 11 in the vertical direction is the tension side. Applying prestress on this side can make the entire cross section of the side near the groove 11 be compressed, so as to significantly increase the ability of the pier body 1 to resist overturning bending moment. Through the cooperation of the first prestressed member and the second prestressed member 63, the sightseeing area 5 and the platform panel 13 built on the pier body 1 and the part of the pier body 1 that serves as the activity point can have higher safety performance.

[0038] In some optional embodiments, the pier body 1 includes a main pier 14 and a support pier 15 integrally connected to the top surface of the main pier 14. In this embodiment, the main pier 14 and the support pier 15 are constructed as a single unit. In some other embodiments, the support pier 15 can also be constructed by setting embedded parts and then casting after the main pier 14 is completed. An expansion joint is provided between the support pier 15 and the beam body 2 along the transverse direction of the bridge. The top surface of the support pier 15 extends integrally to form the platform panel 13 on the side away from the beam body 2. In this embodiment, the second prestressed member 63 is provided on the side of the support pier 15 closer to the beam body 2, and the first prestressed member is provided on the side of the support pier 15 closer to the main pier 2. On one side of pier 14, an expansion joint is provided between the supporting pier 15 and the beam 2 to ensure that the two do not interact under temperature effects. When the beam 2 and the supporting pier 15 are affected by temperature forces, live loads such as vehicles, the deformation direction and magnitude differ greatly. Therefore, sufficient space is provided between the beam 2 and the supporting pier 15 to prevent additional stress on the structure due to displacement restriction under normal use conditions. Furthermore, the main pier 14 serves as the vertical support of the beam 2, but it has no transverse support. That is, the sightseeing platform will not restrict the lateral displacement of the beam 2 under normal working conditions. An expansion joint is provided between the supporting pier 15 and the beam 2. Under seismic conditions, the supporting pier 15 can also serve as a seismic stop for the beam 2. Since the supporting pier 15 is built on top of the main pier 14, and the top surface of the supporting pier 15 extends integrally to one side to form a platform panel 13, the location of the platform panel 13 in the bridge is determined based on the main pier 14. In the overall structure of the bridge, platform panels 13 can be built on top of all the main piers 14, or platform panels 13 can be built on top of some of the main piers 14. See [reference needed]. Figure 3As shown, preferably, there are no platform panels 13 in the bridge, and cantilever 21 is provided on both sides of the beam 2 in the transverse direction, and the cantilever 21 on both sides is symmetrically arranged along the beam 2.

[0039] See Figure 1 As shown, in some optional embodiments, the sightseeing area 5 includes a pedestrian section 51 and a non-motorized vehicle section 52. The pedestrian section 51 and the non-motorized vehicle section 52 are arranged along the transverse direction of the bridge, and the non-motorized vehicle section 52 is located on the side of the pedestrian section 51 closer to the beam 2. That is, the non-motorized vehicle section 52 is closer to the beam 2 than the pedestrian section 51. In this embodiment, part of the non-motorized vehicle section 52 is located on the beam 2. Since the sightseeing area 5 is located on the top surface of the platform panel 13 and the pier body 1, it is located on the platform. The top surfaces of the platform panel 13 and the supporting pier 15, and the top surface of the beam 2 are flush with the top surface of the platform panel 13, that is, the top surface of the beam 2 is flush with the top surface of the supporting pier 15. The portion of the non-motorized vehicle section 52 on the beam 2 and the other portion on the supporting pier 15 are also flush, making the non-motorized vehicle section 52 more level. The beam 2 includes both motorized and non-motorized vehicle lanes, which are also laid out along the transverse direction of the bridge and separated by the bridge crash barrier 7. Preferably, the top surface of the pedestrian section 51 is higher than the top surface of the non-motorized vehicle section 52, which effectively prevents collisions between lingering tourists and non-motorized vehicles, and the higher height of the pedestrian section 51 enhances the viewing experience.

[0040] See Figure 2 As shown, in some optional embodiments, the pedestrian section 51 includes a viewing platform 511, the top surface of which is higher than the top surface of the platform panel 13. The viewing platform 511 has steps on three sides, and a guardrail 5111 is provided on the side of the top surface of the viewing platform 511 closest to the beam. The three sides of the viewing platform 511 with steps can be the two sides of the platform panel 13 extending longitudinally along the bridge and the side of the platform panel 13 away from the beam 2. The steps allow for more people to view the scenery, and the steps on all three sides provide a 360-degree unobstructed view. In this embodiment, no steps are provided on the side of the viewing platform 511 closest to the beam 2 to prevent collisions between standing tourists and non-motorized vehicles. Since this side is higher, a guardrail 5111 is provided to enhance the safety of the viewing platform 511 and prevent the risk of falls. Preferably, guardrails 5111 are provided at each edge of the platform panel 13 away from the beam 2.

[0041] See Figures 4 to 6As shown, in some optional embodiments, a portion of the viewing platform 511 is located on the top surface of the platform panel 13, and another portion is located on the top surface of the support pier 15. The portion of the viewing platform 511 located on the platform panel 13 is a hollow structure. Under the premise of satisfying the overall load-bearing capacity of the viewing platform 511, making the portion of the viewing platform 511 located on the platform panel 13 a hollow structure can effectively reduce the weight on the platform panel 13 and enhance the overall safety of the viewing platform.

[0042] Preferably, the support pier 15 is a solid structure. Making the support pier 15 a solid structure can reduce stress. In some other embodiments, the support pier 15 can also be partially hollow to reduce the amount of engineering work. The edges of the cross-section of the support pier 15 in the horizontal direction coincide with the sides of the main pier 14. The main pier 14 is usually a rectangular structure. In this embodiment, the cross-section of the support pier 15 is also rectangular, and three sides of its cross-section coincide with the sides of the main pier 14, so that the shape of the support pier 15 and the main pier 14 have good consistency. At the same time, it blocks the beam 2 from the side, resulting in a good landscape effect. In some other embodiments, the cross-section of the support pier 15 in the horizontal direction can also be circular or other shaped cross-sections.

[0043] In some optional embodiments, the platform panel 13 has a box-shaped cross-section on the side away from the beam 2, and a solid cross-section on the side closer to the beam. In this embodiment, the viewing platform 511, which is a hollow structure, is integrated with the platform panel 13. Using a box-shaped cross-section on the side of the platform panel 13 away from the beam 2 reduces its self-weight, while using a solid cross-section on the side of the platform panel 13 closer to the support pier 15 reduces stress. Preferably, the cross-sectional dimensions of the platform panel 13 and the viewing platform 511 are determined comprehensively based on the overall dimensions required for the construction of the viewing platform and the location of the driveway.

[0044] Preferably, both the triangular stiffener 4 and the platform panel 13 are made of metal. Using metal for both the triangular stiffener 4 and the platform panel 13 can reduce the weight while still increasing the overall size of the viewing platform. In some other embodiments, the triangular stiffener 4 and the platform panel 13 can also be made of UHPC material, etc., and the support pier 15 is usually made of concrete, which is easy to cast and durable.

[0045] Preferably, the platform panel 13, the support pier 15, and the main pier 14 can be regarded as an integrally formed Z-shaped pier. Alternatively, the platform panel 13 can be constructed by setting embedded parts and then casting. The support pier 15 and the main pier 14 form an "L" shape, and the beam 2 is located in the groove 11 of the "L". In this case, the platform panel 13 is built on the side of the support pier 15 near the top, so that the load generated by the sightseeing area 5 and pedestrians is transferred to the support pier 15 through the platform panel 13, and then to the main pier 14.

[0046] In some alternative embodiments, a method for constructing a bridge may also be provided, which may include the following steps:

[0047] S1: The conventional substructure of the construction bridge, including the pile foundation and the main pier 14 below the bearing 3, etc.

[0048] S2: After the pile foundation and the part below the support 3 are completed, support 3 is constructed on the top surface of the main pier 14 to bear the load of beam 2. At the same time, support pier 15 is constructed on the top surface of the main pier 14, so that the main pier 14 and support pier 15 are connected to form an "L" shaped structure. While constructing support pier 15, anchor point 62 is constructed on the top surface of the main pier 14 near support pier 15. One end of the second prestressed member 63 is fixed to the anchor point 62 and pre-embedded. A third tensioning point 61 is set on the side of the support pier 15 away from the main pier 14 in the vertical direction, so that one end of the second prestressed member 63 extends into the third tensioning point 61.

[0049] S3: Construct beam 2 on the top surface of support 3. In order to ensure that the force of the sightseeing platform can be evenly transmitted to the lower part of the main pier 14, in the range of bridges with sightseeing platforms, beam 2 is designed as having no cantilever 21 on one side, and an appropriate gap is maintained between beam 2 and the "L"-shaped pier to ensure that the two do not interact under temperature action; in the range of bridges without sightseeing platforms, beam 2 still maintains the symmetrical arrangement of cantilever 21 on both sides along beam 2; platform panel 13 can be constructed simultaneously at this time. At this time, by setting embedded parts, embedded steel bars, etc., the triangular stiffener 4 and platform panel 13 are constructed to form a "Z"-shaped pier with platform panel 13 and "L"-shaped pier.

[0050] S4: Continue construction of the viewing platform 511 on the foundation of platform panel 13. By setting specific steps on the viewing platform 511, the pedestrian section 51 and the non-motorized vehicle section 52 can be separated, preventing collisions between lingering tourists and non-motorized vehicles. The edge of the viewing platform 511 near beam 2 is determined by the width of the non-motorized vehicle section 52. Multiple steps are used to increase the height of the viewing platform 511, avoiding mutual interference between lingering tourists and vehicles, while improving the viewing effect and providing tourists with a 360-degree unobstructed view. Simultaneously, support 3 can be used as the second tensioning point, and the first tensioning point can be set on one side of the support pier 15. After connecting the first and second tensioning points with the first prestressed member, the prestressing tension of the first prestressed member is completed, and the previously pre-embedded second prestressed member 63 is also simultaneously or sequentially tensioned. The application of prestress increases the compressive stress reserve on the side of the support pier 15 near beam 2, preventing excessive tensile stress on one side of the support pier 15 and increasing the safety redundancy of the "Z"-shaped pier.

[0051] S5: Continue construction of bridge railings, curbs, paving, expansion joints, etc., on the top surface of beam 2, the top surface of support pier 15, platform panel 13, and viewing platform 511 to complete the bridge construction. Beam 2 and support pier 15 are connected only by expansion joints. Preferably, flowers, plants, children's slides, and other landscape features can be arranged on the steps of viewing platform 511 to further enhance its landscape effect and increase the interest of the viewing platform.
