This can lead to uneven stress on the superstructure of the bridge body, causing stress concentration or local internal force exceeding the limit. Utility Model Content

[0003] The purpose of this invention is to provide a suspended platform assembly for bridges to improve the aforementioned problems. To achieve this purpose, the technical solution adopted by this invention is as follows:

[0004] This application provides a suspended platform assembly for a bridge, comprising: a concrete platform disposed near the top of a pier and connected to the pier, the concrete platform being disposed around the outer periphery of the pier; and a surrounding panel disposed around the outer periphery of the concrete platform, the surrounding panel, the concrete platform, and the pier defining a pedestrian space with an open top.

[0005] According to some embodiments of the present invention, the enclosure is provided with two side walls with open tops on the two side walls in the extension direction of the bridge body, and the inner peripheral wall of the enclosure is adapted to fit against the outer peripheral wall of the bridge body.

[0006] According to some embodiments of the present invention, a sealing element is also included, which is disposed between the inner peripheral wall of the receiving groove and the outer peripheral wall of the bridge body, and the sealing element is adapted to be connected to the enclosure and the bridge body respectively.

[0007] According to some embodiments of the present invention, the sealing element includes a corrugated plate, the extension direction of the corrugated plate is parallel to the extension direction of the bridge body, one end of the corrugated plate is connected to the surrounding plate, and the other end of the corrugated plate is connected to the bridge body through a sealing plate.

[0008] According to some embodiments of the present invention, the sealing plate includes a first plate and a second plate. The sidewall of the first plate is connected to the end of the corrugated plate, and the two sides of the second plate in the thickness direction are respectively connected to the first plate and the outer peripheral wall of the bridge body.

[0009] According to some embodiments of the present invention, a first sealing rubber is provided between the corrugated plate and the surrounding plate, a second sealing rubber is provided between the corrugated plate and the first plate body, and / or a third sealing rubber is provided between the second plate body and the outer peripheral wall of the bridge body.

[0010] According to some embodiments of the present invention, a base plate is also included, which is arranged around the outer peripheral wall of the pier and is located on the side of the concrete platform away from the bridge body. The base plate is connected to the surrounding plate.

[0011] According to some embodiments of the present invention, the enclosure, bottom plate and / or corrugated plate are made of stainless steel.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-5 As shown, this embodiment provides a suspended platform assembly for a bridge, including a concrete platform 10 and a surrounding panel 20. The concrete platform 10 is disposed near the top of the pier 1 and connected to the pier 1. The concrete platform 10 is disposed around the outer periphery of the pier 1. The surrounding panel 20 is disposed around the outer periphery of the concrete platform 10. The surrounding panel 20, the concrete platform 10 and the pier 1 define a pedestrian space with an open top.

[0027] In some embodiments, the concrete platform 10 is positioned near the top of the pier 1 and is directly connected to the pier 1, serving as a base for maintenance personnel to walk on. The concrete platform 10 surrounds the outer perimeter of the pier 1, forming a closed ring structure to ensure that maintenance personnel can walk safely around the pier 1. It should be noted that the concrete platform 10 can be integrally cast with the pier 1, or it can be cast in place on the existing pier 1; no limitation is made here. Of course, the inner peripheral wall of the concrete platform 10 is completely fitted with the outer peripheral wall of the pier 1 to ensure the airtightness between the concrete platform 10 and the pier 1, thereby preventing water from entering the pedestrian space through the gap between the concrete platform 10 and the pier 1.

[0028] The enclosure 20 is set around the outer perimeter of the concrete platform 10, and the enclosure 20 and the concrete platform 10 are sealed together. Thus, the enclosure 20, the concrete platform 10 and the pier 1 can define a pedestrian space that is only open at the top. In the event of rising water level or sudden flood, the concrete platform 10 and the enclosure 20 can block water and prevent water from entering the pedestrian space and causing erosion to the support and other structures between the pier 1 and the bridge body 2.

[0029] According to the present invention, a suspended platform assembly for bridges is provided. By setting up a concrete platform 10 surrounding the bridge pier 1 and a surrounding panel 20 surrounding the concrete platform 10, a pedestrian space is formed between the surrounding panel 20, the concrete platform 10 and the bridge pier 1, which is only open at the top. This prevents water from entering the pedestrian space during rising water levels or sudden floods, thereby preventing water from eroding the supports and other structures between the bridge pier 1 and the bridge body 2. This also prevents stress concentration or local internal force exceeding limits caused by uneven stress on the upper structure of the bridge body 2, extends the service life of the bridge, and reduces the risks of railway operation and the workload of maintenance.

[0030] According to some embodiments of the present invention, the enclosure 20 is provided with two side walls with open tops on the two side walls in the extension direction of the bridge body 2, and the inner peripheral wall of the enclosure 21 is adapted to fit against the outer peripheral wall of the bridge body 2.

[0031] In some embodiments, the enclosure 20 has two open-top receiving grooves 21 on its two side walls along the extension direction of the bridge body 2. The receiving grooves 21 extend through the thickness of the enclosure 20, allowing the bridge body 2 to be embedded. It should be noted that the bottom surface and at least part of the side surfaces of the bridge body 2 are in contact with the inner peripheral wall of the receiving groove 21. Therefore, the enclosure 20 can be made taller, further improving its water-resistant effect and preventing water from entering the pedestrian space.

[0032] It is understandable that the outer perimeter of the bridge body 2 (such as a box girder or T-beam) is usually a regular curved surface or a plane. The inner perimeter of the receiving groove 21 matches the shape of the bridge body 2, ensuring that there is no significant gap after the bridge body 2 is embedded, so as to block most of the direct water flow path and reduce the amount of rainwater or flood seeping in along the joint between the bridge body 2 and the receiving groove 21.

[0033] According to some embodiments of the present invention, the suspended basket assembly further includes a sealing element, which is disposed between the inner peripheral wall of the receiving groove 21 and the outer peripheral wall of the bridge body 2, and the sealing element is adapted to be connected to the enclosure 20 and the bridge body 2 respectively.

[0034] In some embodiments, the seal is disposed between the inner peripheral wall of the receiving groove 21 and the outer peripheral wall of the bridge body 2. That is, the seal can fill the gap between the receiving groove 21 and the bridge body 2 to form a sealing layer, thereby further ensuring the sealing performance between the receiving groove 21 and the bridge body 2. The seal can be a flexible material such as a rubber waterstop or other sealing structure, which is not limited here.

[0035] According to some embodiments of the present invention, the sealing element includes a corrugated plate 31, the extension direction of the corrugated plate 31 is parallel to the extension direction of the bridge body 2, one end of the corrugated plate 31 is connected to the surrounding plate 20, and the other end of the corrugated plate 31 is connected to the bridge body 2 through a sealing plate 32.

[0036] In some embodiments, the corrugated plate 31 is an elastic plate with a corrugated cross-section. The extension direction of the corrugated plate 31 is parallel to the extension direction of the bridge body 2 (i.e., the corrugated plate 31 is arranged along the longitudinal direction of the bridge) to ensure that the deformation direction of the corrugated plate 31 is consistent with that of the bridge body 2, thereby accommodating the longitudinal expansion and contraction of the bridge body 2 caused by temperature and load. When the bridge body 2 undergoes longitudinal expansion and contraction due to temperature changes or load, the corrugated plate 31 absorbs the displacement through compression or stretching of the corrugated folds, preventing the seals from tearing due to rigid connections.

[0037] It can be understood that one end of the corrugated plate 31 is connected to the surrounding plate 20 by mechanical fixing (such as bolts, welding) or bonding, and the other end of the corrugated plate 31 is connected to the bridge body 2 through a sealing plate 32. The sealing plate 32 is used to fill the local gap between the corrugated plate 31 and the bridge body 2 and is fixed by bolts, sealant or beadings.

[0038] According to some embodiments of the present utility model, the sealing plate 32 includes a first plate body 321 and a second plate body 322. The side wall of the first plate body 321 is connected to the end of the corrugated plate 31, and both sides in the thickness direction of the second plate body 322 are respectively connected to the first plate body 321 and the outer peripheral wall of the bridge body 2.

[0039] In some embodiments, the first plate body 321 is a vertical plate, and the first plate body 321 forms a groove with an open top. The first plate body 321 is adapted to provide a connection position for the corrugated plate 31, facilitating the connection between the corrugated plate 31 and the sealing plate 32, while ensuring the sealing performance between the first plate body 321 and the corrugated plate 31. The inner peripheral wall of the groove is connected to the second plate body 322. The second plate body 322 is of a "U" - shaped structure, and the "U" - shaped second plate body 322 is designed to fit the bottom surface and the side surface of the bridge body 2, ensuring the connection stability and sealing performance between the second plate body 322 and the bridge body 2. The first body and the second plate body 322 are fully welded or integrally formed to ensure the sealing performance between the first plate body 321 and the second plate body 322.

[0040] Thus, through the above - mentioned settings, the connection stability and sealing performance among the sealing plate 32, the corrugated plate 31 and the bridge body 2 can be ensured, further preventing water from invading the pedestrian space.

[0041] It should be noted that the second plate body 322 is a horizontal plate, and both ends of the horizontal plate are upturned to form the "U" - shaped second plate body 322. Thus, the contact area between the second plate body 322 and the bridge body 2 in the horizontal direction is large, ensuring the connection stability and sealing performance between the second plate body 322 and the bridge body 2.

[0042] According to some embodiments of the present utility model, a first sealing rubber is provided between the corrugated plate 31 and the surrounding plate 20, a second sealing rubber is provided between the corrugated plate 31 and the first plate body 321, and / or a third sealing rubber is provided between the second plate body 322 and the outer peripheral wall of the bridge body 2.

[0043] In some embodiments, a first sealing rubber may be provided between the corrugated plate 31 and the surrounding plate 20; a second sealing rubber may be provided between the corrugated plate 31 and the first plate 321; a third sealing rubber may be provided between the second plate 322 and the outer peripheral wall of the bridge body 2; or a first sealing rubber may be provided between the corrugated plate 31 and the surrounding plate 20, and a second sealing rubber may be provided between the corrugated plate 31 and the first plate 321; or a first sealing rubber may be provided between the corrugated plate 31 and the surrounding plate 20. Furthermore, a third sealing rubber is provided between the second plate 322 and the outer peripheral wall of the bridge body 2. Alternatively, a second sealing rubber is provided between the corrugated plate 31 and the first plate 321, and a third sealing rubber is provided between the second plate 322 and the outer peripheral wall of the bridge body 2. Alternatively, a first sealing rubber is provided between the corrugated plate 31 and the surrounding plate 20, a second sealing rubber is provided between the corrugated plate 31 and the first plate 321, and a third sealing rubber is provided between the second plate 322 and the outer peripheral wall of the bridge body 2. There are no restrictions here.

[0044] Understandably, the first sealing rubber can enhance the sealing between the corrugated plate 31 and the surrounding plate 20, the second sealing rubber can enhance the sealing between the corrugated plate 31 and the sealing plate 32, and the third sealing rubber can enhance the sealing between the sealing plate 32 and the bridge body 2. Thus, the sealing between the surrounding plate 20 and the bridge body 2 can be further enhanced by the first, second, and third sealing rubbers, further preventing water from entering the pedestrian space.

[0045] According to some embodiments of the present invention, the suspended platform assembly also includes a base plate 50, which is arranged around the outer peripheral wall of the pier 1 and is located on the side of the concrete platform 10 away from the bridge body 2. The base plate 50 is connected to the surrounding plate 20.

[0046] In some embodiments, the base plate 50 is disposed on the side of the concrete platform 10 away from the bridge body 2, and the base plate 50 is disposed around the outer peripheral wall of the pier 1. The inner peripheral wall of the base plate 50 is in contact with the outer peripheral wall of the pier 1, and a fourth sealing rubber is disposed between the inner peripheral wall of the base plate 50 and the outer peripheral wall of the pier 1. The outer peripheral wall of the base plate 50 is fully welded to the bottom of the surrounding plate 20.

[0047] Therefore, the base plate 50 can improve the connection strength between the enclosure 20 and the concrete platform 10, thereby improving the structural strength of the suspended platform assembly. At the same time, the base plate 50 can further seal the bottom of the pedestrian space to enhance the sealing effect of the pedestrian space and prevent water from entering between the enclosure 20 and the concrete platform 10.

[0048] According to some embodiments of the present invention, the enclosure 20, the bottom plate 50, and / or the corrugated plate 31 are made of stainless steel.

[0049] In some embodiments, the enclosure 20 may be made of stainless steel; the bottom plate 50 may be made of stainless steel; the corrugated plate 31 may be made of stainless steel; the enclosure 20 and the bottom plate 50 may be made of stainless steel; the bottom plate 50 and the corrugated plate 31 may be made of stainless steel; the enclosure 20 and the corrugated plate 31 may be made of stainless steel; or the enclosure 20, the bottom plate 50 and the corrugated plate 31 may all be made of stainless steel, without limitation.

[0050] It is understood that the type of stainless steel can be austenitic stainless steel (such as 304, 316L) or duplex stainless steel (such as 2205), and there is no limitation herein. By making the enclosure 20, the base plate 50 and / or the corrugated plate 31 made of stainless steel, this application can improve the durability of the suspended platform assembly, thereby extending the service life of the suspended platform assembly and reducing the maintenance frequency of the suspended platform assembly.

[0051] According to some embodiments of the present invention, a plurality of transverse reinforcing ribs 41 and a plurality of longitudinal reinforcing ribs 42 are provided on the side of the enclosure 20 facing the pier 1. The plurality of transverse reinforcing ribs 41 are spaced apart along the height direction of the enclosure 20, and the plurality of longitudinal reinforcing ribs 42 are spaced apart along the circumference of the enclosure 20. The plurality of transverse reinforcing ribs 41 are respectively connected to the plurality of longitudinal reinforcing ribs 42.

[0052] In some embodiments, transverse stiffeners 41 are spaced apart along the height direction of the enclosure 20, and the number of transverse stiffeners 41 is greater than or equal to 2. The spacing is determined according to the height of the enclosure 20 and the load requirements (the distance between two adjacent transverse stiffeners 41 is between 100mm and 300mm); longitudinal stiffeners 42 are spaced apart along the circumference of the enclosure 20, and the number of longitudinal stiffeners 42 is greater than or equal to 3. The spacing is determined according to the perimeter of the enclosure 20 and the bending resistance requirements (the distance between two adjacent longitudinal stiffeners 42 is between 150mm and 400mm). Multiple transverse stiffeners 41 and multiple longitudinal stiffeners 42 are welded to the inner side of the enclosure 20 to form a rigid grid structure.

[0053] Understandably, the longitudinal stiffener 42 can resist the bending deformation of the enclosure 20 in the height direction and improve the bending stiffness of the enclosure 20 by increasing the moment of inertia of the section. The transverse stiffener 41 can resist the torsional deformation of the enclosure 20 in the circumferential direction and enhance the torsional stiffness by forming a closed circumferential structure. The transverse stiffener 41 and the longitudinal stiffener 42 are cross-connected, dividing the enclosure 20 into multiple small units and forming a rigid grid structure. As a result, the local stress on the enclosure 20 can be distributed to the entire rigid grid structure, avoiding local buckling caused by stress concentration.

[0054] Therefore, the provision of transverse reinforcing ribs 41 and longitudinal reinforcing ribs 42 can improve the structural strength of the enclosure 20. Specifically, the provision of transverse reinforcing ribs 41 and longitudinal reinforcing ribs 42 can prevent the enclosure 20 from deforming due to thermal expansion and contraction; and when the water level rises, the provision of transverse reinforcing ribs 41 and longitudinal reinforcing ribs 42 can help the enclosure 20 better resist the impact force from water or floating objects, as well as the water pressure (when the water level rises to between the bottom and top of the enclosure 20, the water will exert a pressure on the enclosure 20).

[0055] It should be noted that all transverse stiffeners 41 and longitudinal stiffeners 42 are located on the side of the enclosure 20 facing the pier 1 (i.e., the inner side), to avoid the transverse stiffeners 41 and longitudinal stiffeners 42 being exposed and affecting the aesthetics, and to prevent the transverse stiffeners 41 and longitudinal stiffeners 42 from being corroded by the environment (such as rainwater and ultraviolet rays).

[0056] According to some embodiments of the present invention, the concrete platform 10 is provided with a one-way drain valve 60, which is suitable for draining water in the pedestrian space to the external environment.

[0057] In some embodiments, the thickness direction of the concrete platform 10 is parallel to the height direction of the pier 1, and the concrete platform 10 is provided with a drainage hole that extends through the thickness direction, and a one-way drainage valve 60 is provided in the drainage hole.

[0058] It is understandable that rainwater may enter from the top of the pedestrian space, and the water in the pedestrian space can be discharged to the external environment through the one-way drain valve 60. That is, when there is water in the pedestrian space, the gravity of the water will cause the sealing plate inside the one-way drain valve 60 to rotate away from the pedestrian space, and the water can be discharged from the pedestrian space under the action of gravity.

[0059] It should be noted that the one-way drain valve 60 can only be opened from one side of the pedestrian space. Therefore, when the water level rises, the rising water level will not cause the one-way drain valve 60 to open, so as to prevent water from entering the pedestrian space through the one-way drain valve 60 due to the rising water level.

[0060] Preferably, the surface of the concrete platform 10 is inclined so that water in the pedestrian space can flow quickly to the one-way drain valve 60 and be discharged under the action of gravity.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
