Description

Technical Field

[0001] The present invention particularly relates to a bridge crossing structure and a bridge structure including the same. Background Art

[0002] The bridge crossing structure is often applied in building structures or bridge structures, and its purpose is to facilitate the passage of vehicles or pedestrians. The bridge crossing for passage use includes a platform and guardrails. Due to the need for passage, the structure of the platform is usually set to be relatively large. At the same time, the single-piece weight of the platform is also relatively heavy, and the weight of the platform can reach up to 30 KG at most. It is extremely inconvenient during storage and use, and it is difficult to cooperate with other guardrails. The platform and the guardrails are usually set as an integral structure, and it is very easy to cause the guardrails connected to the platform to be squeezed and skewed or damaged during transportation, resulting in great potential safety hazards for the guardrails during transportation. At the same time, the guardrails are prone to deformation and fracture due to extrusion or collision, and the complex guardrail structure is difficult to repair, often resulting in a very short actual service life of the bridge crossing, which does not match its relatively high cost. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects that the platform of the existing bridge crossing is difficult to transport and the guardrails of the bridge crossing are easily damaged during transportation, and to provide a bridge crossing structure and a bridge structure including the same.

[0004] The present invention solves the above technical problem through the following technical solutions:

[0005] A bridge crossing structure, the bridge crossing structure includes a platform, the bridge crossing structure further includes a connecting part, the connecting part is arranged at the edge of the platform, the bridge crossing structure further includes a protection structure, the protection structure is detachably connected to the connecting part, a weight reduction hole is arranged on the platform, the weight reduction hole is arranged along the thickness direction of the platform and the opening of the weight reduction hole is located on the upper surface of the platform, adjacent two weight reduction holes are communicated with each other, the weight reduction hole is communicated with the edge of the platform, the surface of the protection structure has a concave part, and the concave part is arranged corresponding to the weight reduction hole, and the concave part is arranged to extend into the weight reduction hole when the protection structure is stacked on the platform.

[0006] In this solution, the platform is detachably connected to the protective structure. As a result, during transportation, the platforms can be stacked on the upper surface of the platform for transportation, and the platform can be placed on a pallet with the protective structure stacked on top of it. This ensures that the protective structure is not installed on the platform during transportation to avoid deformation or damage caused by the pallet squeezing the protective structure, improving the transportation efficiency of the bridge and reducing the problem of excessive cost for bridge installation during transportation. Additionally, the protective structure is provided with a recess. When multiple protective structures are stacked, the recess of one protective structure extends into the recess of another protective structure to prevent the multiple protective structures from sliding horizontally during stacked transportation, thereby avoiding damage caused by the protective structure falling off the transportation pallet. Further, the platform is provided with weight-reducing holes. The weight-reducing holes are correspondingly arranged with the recesses, such that when the protective structure is stacked on the platform, the recesses of the protective structure in contact with the platform correspondingly extend into the weight-reducing holes to prevent the protective structure from sliding horizontally when the protective structure and the platform are stacked for transportation simultaneously. At the same time, the weight-reducing holes are interconnected with each other and communicate to the edge of the platform. The opening direction of the weight-reducing holes is located on the upper surface of the platform. The height of the weight-reducing holes is lower than the upper surface of the platform, reducing the self-weight of the platform for easy transportation and enabling the platform to receive rainwater and artificial sprinkling that fall on the platform, realizing the drainage function of the platform.

[0007] Preferably, the connecting portion is provided with an insertion opening, and the end of the protective structure is inserted into the insertion opening.

[0008] In this solution, the insertion opening is arranged at the edge of the platform and is used to accommodate the end of the protective structure. The protective structure is inserted into the insertion opening to realize the detachable connection between the platform and the protective structure.

[0009] Preferably, the bridge structure further includes a locking portion, and the locking portion is used to contact the end of the protective structure and lock or unlock the protective structure and the connecting portion.

[0010] In this solution, the locking portion is used to lock or unlock the end of the protective structure extending into the insertion opening of the connecting portion, thereby preventing the protective structure from falling off when the platform is connected to the protective structure and avoiding safety problems with the bridge structure.

[0011] Preferably, the locking portion includes a locking rod. A threaded hole is formed in the connecting portion, and the threaded hole communicates with the insertion opening. The end of the locking rod is provided with an external thread, and the locking rod is threadedly connected to the threaded hole.

[0012] In this solution, the locking rod is provided with an external thread, and a threaded hole is arranged on the side of the insertion opening. The locking rod is screwed corresponding to the threaded hole, and the end of the screw rod extends into the insertion opening and abuts against the periphery of the protective structure, thereby realizing the locking of the protective structure. The protective structure and the platform are integrally connected. When unlocking, the locking rod is rotated in the reverse direction so that the end of the locking rod moves away from the periphery of the protective structure to realize the unlocking of the protective structure.

[0013] Preferably, the protection structure includes a vertical rod and a horizontal rod. The horizontal rod is perpendicular to the vertical rod, and the end of the vertical rod is connected to the connecting portion.

[0014] In this solution, the horizontal rod and the vertical rod are arranged in a perpendicular direction. One end of the vertical rod extends into the insertion opening of the connecting portion and is connected to the platform, while the horizontal rod is used to protect vehicles or pedestrians passing on the bridge structure along the traveling direction of the platform to prevent them from falling or dropping from the bridge structure.

[0015] Preferably, the connecting portion includes a first connecting member and a second connecting member. The first connecting member is located below the platform, and both ends of the first connecting member extend out of the two side edges of the platform respectively. The second connecting member is connected to one end of the first connecting member, and the insertion opening is located on the second connecting member.

[0016] In this solution, the first connecting member is arranged below the platform, and both ends of the first connecting member extend out of the two side edges of the platform. One end of the first connecting member is connected to the second connecting member, and the insertion opening is arranged on the second connecting member. By arranging the first connecting member below the platform and connecting the first connecting member and the second connecting member with the platform through the insertion opening, there is no need to set an insertion opening on the platform, ensuring the passage space for vehicles or pedestrians on the platform.

[0017] Preferably, the bridge structure further includes a mounting portion, and the mounting portion is arranged at the end of the first connecting member away from the second connecting member.

[0018] In this solution, the mounting portion is used for further connection of the bridge structure with other structures, and by arranging the mounting portion away from the second connecting member, interference between the mounting portion and the protection structure can be avoided.

[0019] Preferably, the first side of the second connecting member is consistent with the extending direction of the upper surface of the platform, and the insertion opening is located on the first side. The second side of the second connecting member is perpendicular to the first connecting member.

[0020] In this solution, by setting the first side of the second connecting member to be consistent with the extending direction of the upper surface of the platform, the protection structure can be connected to the insertion opening arranged on this side and ensure that the protection structure is perpendicular to the platform. The second side of the second connecting member is perpendicular to the first connecting member to achieve smooth connection with the end of the first connecting member.

[0021] Preferably, the weight-reducing hole penetrates the platform along the thickness direction of the platform.

[0022] In this solution, the weight-reducing hole penetrates the platform to further improve the drainage effect and weight-reducing effect of the weight-reducing hole.

[0023] A bridge structure, the bridge structure includes the bridge-crossing structure as described above, and the side of the bridge structure is connected to the installation part of the bridge-crossing structure.

[0024] In this solution, the bridge-crossing structure includes the above-mentioned platform, connecting part and protective structure. The protective structure is detachably connected to the platform through the connecting part, so that the bridge structure adopting this bridge-crossing structure can avoid damage to the protective structure during transportation and installation, ensure the construction period and reduce the construction cost.

[0025] The positive and progressive effects of the present invention are as follows: by setting the connecting part, the platform and the protective structure are detachably connected, so that when transporting the platform before installing the bridge-crossing structure, the platform and the protective structure can be stacked and transported, ensuring that the protective structure is not squeezed by the tray of the bearing platform during transportation, avoiding damage to the protective structure, and at the same time, it can be transported through existing transportation devices during transportation, which is more convenient and avoids a series of problems caused by the integrated transportation of the protective structure and the platform. In addition, the protective structure is provided with a recessed part. When multiple protective structures are stacked, the recessed part of one protective structure extends into the recessed part of another protective structure to prevent the multiple protective structures from sliding horizontally during stacked transportation, thereby avoiding the protective structure falling off the transportation tray and being damaged. Further, the platform is provided with weight-reducing holes, and the weight-reducing holes are correspondingly arranged with the recessed parts, so that when the protective structure is stacked on the platform, the recessed part of the protective structure in contact with the platform correspondingly extends into the weight-reducing holes to prevent the protective structure from sliding horizontally when the protective structure and the platform are stacked and transported at the same time. At the same time, the weight-reducing holes are interconnected with each other and communicate with the edge of the platform. The opening direction of the weight-reducing holes is located on the upper surface of the platform, and the height of the weight-reducing holes is lower than the upper surface of the platform, so that the self-weight of the platform is reduced, which is convenient for the transportation of the platform and can receive the rainwater and artificially sprinkled water falling on the platform, realizing the drainage function of the platform.

[0034] Installation part 4 Detailed Description of the Invention

[0035] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments for this reason.

[0036] This embodiment provides a bridge structure, and the specific structure is as Figure 1 shown. The bridge structure includes a platform 1, the platform 1 is a rectangular plate with a flat surface. In addition, the bridge structure further includes a connecting portion 2, the connecting portion 2 is arranged at the edge of the platform 1, and the bridge structure further includes a protection structure 3, the protection structure 3 is detachably connected to the connecting portion 2. Thus, when transporting the platform 1 before installation of the bridge structure, the protection structure 3 can be separated from the platform 1, and when installing the bridge structure, the protection structure 3 can be smoothly connected to the platform 1. The separately provided platform 1 and the protection structure 3 can be transported separately or stacked together for transportation. By changing the connection relationship between the platform 1 and the protection structure 3, it is possible to avoid the protection structure 3 being integrally provided with the platform 1 during transportation and the protection structure 3 being arranged in a vertical direction with the platform 1, so that the protection structure 3 is squeezed and deformed or damaged. This reduces the weight when transporting the bridge structure and reduces the problem of the bridge structure installation cost being too high due to damage or deformation of the protection structure 3, and also improves the transportation efficiency of the platform 1 and the protection structure 3.

[0037] In addition, weight-reducing holes are provided on the platform 1. There are multiple weight-reducing holes, which are arranged in sequence on the upper surface of the platform 1. The weight-reducing holes extend along the thickness direction of the platform 1, and the openings of the weight-reducing holes are located on the upper surface of the platform 1 for passage. By providing the weight-reducing holes, the platform 1 is lighter in weight compared to the overall plate, which is more convenient for transporting the platform 1 and improves the transportation efficiency. The shape of the weight-reducing holes can be cylindrical or rectangular. Adjacent two weight-reducing holes are interconnected, and the connection part is located on the hole wall of the weight-reducing holes. The weight-reducing holes are also connected to the edge side wall of the platform 1. Through the weight-reducing holes, rainwater or artificially sprinkled water falling on the platform 1 can flow into the weight-reducing holes and be discharged from the upper surface of the platform 1 through the connection part between the weight-reducing holes and the edge side wall of the platform 1, avoiding inconvenience in passage caused by water accumulation in the part of the bridge structure for passage.

[0038] At the same time, a recessed portion is provided on the surface of the protection structure 3. The recessed portion is an arc-shaped groove. The recessed portions of multiple protection structures 3 are correspondingly arranged, so that when multiple protection structures 3 are stacked for transportation, they can be stacked on each other, and the recessed portions of each protection structure 3 can cooperate with each other to realize the limit of the sliding of the corresponding protection structure 3 in the horizontal placement direction of the protection structure 3. Of course, in other embodiments of this embodiment, the recessed portion can also be a rectangular groove or a groove of other shapes, the purpose of which is that the recessed portions of multiple protection structures 3 extend and are positioned. This is the prior art and will not be elaborated here too much.

[0039] In this embodiment, the platform 1 includes a frame and a carrier. The frame and the carrier are made of steel. The frame is a rectangular frame and meets the passing requirements of vehicles or pedestrians on the bridge structure. The carrier is multiple steel plates or steel pipes arranged in the frame. Both ends of the carrier are connected to the frame. In addition, the carrier can also be arranged in a direction perpendicular to the passing direction of the bridge structure, and its purpose is also to bear the passing requirements of vehicles and pedestrians on the bridge structure. This is prior art and will not be elaborated here. And, the weight reduction holes extend along the thickness direction of the carrier, and the weight reduction holes are correspondingly arranged with the recessed parts of the protection structure 3. The platform 1 is transported by a pallet. When the protection structure 3 separated from the platform 1 is transported, it is stacked on the upper surface of the platform 1. The recessed parts of the protection structure 3 in contact with the upper surface of the platform 1 extend into the weight reduction holes of the platform 1. Other protection structures 3 are stacked in the height direction above the protection structure 3 in contact with the upper surface of the platform 1 in sequence. The recessed parts of multiple protection structures 3 extend into the recessed parts below in sequence. By virtue of the characteristic that the platform 1 has a large self-weight, the protection structure 3 in contact with the upper surface of the platform 1 is restricted. Furthermore, the sliding of each protection structure 3 in the horizontal placement direction is restricted by the recessed parts on each protection structure 3 in sequence. When the platform 1 and the protection structure 3 are stacked, it can not only prevent the protection structure 3 from being squeezed and deformed during transportation, but also utilize the pallet of the original transportation platform 1 to transport the platform 1 and the protection structure 3 simultaneously, reducing the transportation cost. And the safety requirements during the stacked transportation of the platform 1 and the protection structure 3 are achieved through the cooperation of the recessed parts and the weight reduction holes, avoiding the safety problems caused by the sliding of the protection structure 3 when the protection structure 3 is stacked on the platform 1.

[0040] In another implementation manner of this embodiment, the weight reduction holes penetrate the platform 1 along the thickness direction of the platform 1, that is to say, the weight reduction holes penetrate the carrier. When rainwater or artificial sprinkling falls on the platform 1, drainage is directly carried out through the weight reduction holes without leaving to the edge side wall of the platform 1, improving the drainage efficiency of the platform 1. At the same time, since the weight reduction holes directly penetrate the carrier, the weight of the carrier is further reduced, and the weight of the platform 1 is also reduced accordingly. This not only enables the platform 1 to be transported more quickly and conveniently, but also ensures that the drainage function of the platform 1 is not affected.

[0041] Furthermore, the connecting part 2 is provided with an insertion opening 21. The insertion opening 21 is a circular hole. The end part of the protection structure 3 is correspondingly arranged as a cylindrical part. Thus, the end part of the protection structure 3 can smoothly extend into the insertion opening 21, and the connection between the protection structure 3 and the platform 1 is realized through the connecting part 2, achieving the overall connection of the bridge structure.

[0042] In other embodiments of this embodiment, internal threads may be provided in the insertion interface 21, and external threads are provided on the outer peripheral side of the end of the protection structure 3 extending into the insertion interface 21. The insertion interface 21 and the protection structure 3 are detachably connected by screwing, which not only improves the stability of the protection structure 3 when connected to the platform 1, but also ensures that the platform 1 and the protection structure 3 are separated and transported separately, thereby avoiding the protection structure 3 being pressed and deformed or damaged when it abuts against the tray carrying the platform 1 during integrated transportation with the platform 1.

[0043] In addition, the bridging structure in this embodiment further includes a locking portion (not shown in the figure), and the locking portion is used to contact the end of the protection structure 3 and lock or unlock the protection structure 3 and the connecting portion 2.

[0044] Specifically, the end of the locking portion extends into the insertion interface 21 of the connecting portion 2 and contacts the outer peripheral side of the protection structure 3, so that the protection structure 3 is prevented from falling off from the insertion interface 21 after being inserted into the insertion interface 21, thereby realizing the locking of the protection structure 3 and the smooth connection between the protection structure 3 and the platform 1.

[0045] Furthermore, the locking portion includes a locking rod. The locking rod is a cylindrical rod. A threaded hole is provided on the side of the insertion interface 21 of the connecting portion 2, and the threaded hole communicates with the insertion interface 21. The end of the locking rod is provided with external threads and the locking rod is threadedly connected to the threaded hole. The operator inserts the end of the locking rod with external threads into the threaded hole and rotates it into the insertion interface 21, so that the end of the locking rod contacts the peripheral surface of the end of the protection structure 3 in the insertion interface 21, realizing the connection between the protection structure 3 and the platform 1. When unlocking, the locking rod is rotated in the reverse direction so that the end of the locking rod moves away from the peripheral side of the protection structure 3 to realize the unlocking of the protection structure.

[0046] Of course, other structures for unlocking and locking in the prior art can also be selected for the locking portion. The purpose is to improve the stability and reliability of the platform 1 and the protection structure 3 through the locking portion during installation. This is the prior art and will not be elaborated here.

[0047] In this embodiment, the protection structure 3 includes vertical rods and horizontal rods. The vertical rods and horizontal rods are made of steel pipes. The diameter of the vertical rods is selected as 48 mm steel pipes to improve the connection stability between the protection structure 3 and the platform 1. The vertical rods are arranged in a direction perpendicular to the platform 1, and the horizontal rods are arranged along the passing direction of the platform 1 and are perpendicular to the vertical rods. The horizontal rods are used to block vehicles or pedestrians from falling from the bridge structure along the passing direction to improve the passing safety of the bridge structure. One end of the vertical rod extends into the insertion opening 21 to be connected to the platform 1, and the other end of the vertical rod is away from the platform 1. Multiple horizontal rods and vertical rods can be provided. For example, multiple vertical rods are arranged at intervals on the protection structure 3 on one side edge of the platform 1, and multiple vertical rods are perpendicularly connected to two or more horizontal rods. By increasing the number of horizontal rods, the use safety of the protection structure 3 is improved.

[0048] In this embodiment, the connection part 2 includes a first connecting piece 22 and a second connecting piece 23. Among them, the first connecting piece 22 is located below the platform 1, and both ends of the first connecting piece 22 extend out of the two side edges of the platform 1. The second connecting piece 23 is connected to one end of the first connecting piece 22, and the insertion opening 21 is located on the second connecting piece 23.

[0049] Specifically, the first connecting piece 22 is a rectangular steel plate and is arranged below the platform 1. Both ends of the first connecting piece 22 extend out of the two side edges of the platform 1, and the part of the first connecting piece 22 located below the platform 1 is fixedly connected to the platform 1. One end of the first connecting piece 22 is connected to the second connecting piece 23. The insertion opening 21 is arranged on the second connecting piece 23, and the opening of the insertion opening 21 is consistent with the surface of the platform 1 for vehicles or pedestrians to pass through. By arranging the first connecting piece 22 below the platform 1 and connecting the insertion opening 21, the first connecting piece 22, and the second connecting piece 23 to the platform 1, it is ensured that the surface of the platform 1 for vehicles or pedestrians to pass through does not need to be provided with the insertion opening 21, thus guaranteeing the passing space of the platform 1 for vehicles or pedestrians.

[0050] Among them, the bridge structure further includes an installation part 4. The installation part 4 is a rectangular steel plate arranged at the end of the first connecting piece 22. The rectangular steel plate is fixedly connected or detachably connected to the end of the first connecting piece 22. The detachable connection uses bolt components in the existing technology for connection. The installation part 4 is used for further connection with other structures, and the protection structure 3 is located at the other end of the first connecting piece 22. By connecting the bridge structure to other structures through the installation part 4, not only the installation space of the bridge structure is reasonably utilized, but also it can be ensured that the original space of the bridge structure for vehicles or pedestrians to pass through is not occupied, and the interference situation caused by insufficient installation space when the installation part 4 and the protection structure 3 are located on the same side and the bridge structure is installed on other structures through the installation part 4 located on the same side as the protection structure 3 after the protection structure 3 is installed on the platform 1 can be avoided.

[0051] In this embodiment, the second connecting member 23 is an angle steel. The cross-section of the angle steel is vertically arranged. The second side edge of the angle steel is arranged in a vertical direction with respect to the first connecting member 22 and is connected to the end of the first connecting member 22. The first side of the angle steel is consistent with the direction of the surface of the platform 1 for vehicle or pedestrian passage, and the insertion interface 21 is located on this side. After the protection structure 3 is inserted into the insertion interface 21, while the protection structure 3 is vertically arranged with respect to the surface of the platform 1, the vertical arrangement of the cross-section of the angle steel is used to improve the stability when the platform 1 and the protection structure 3 are connected, and ensure the protection effect of the protection structure 3 of the bridge structure.

[0052] This embodiment also provides a bridge structure, which includes the above-mentioned bridge structure, and the side part of the bridge structure is connected to the installation part 4 of the bridge structure.

[0053] Specifically, the bridge structure is arranged at the two side edges of the bridge structure. In addition, the bridge structure further includes a bridge body for vehicle passage, and the bridge structure is for pedestrian and bicycle passage, so as to achieve the separation of people and vehicles, and avoid traffic jams and traffic accidents caused by the mixed passage of pedestrians and vehicles. The bridge structure includes the above-mentioned platform 1, connecting part 2, protection structure 3 and installation part 4. The platform 1 and the protection structure 3 are separately arranged and detachably connected. The protection structure 3 and the platform 1 are detachably connected through the connecting part 2. Furthermore, during the transportation and installation of the bridge structure adopting this bridge structure, damage to the protection structure 3 can be avoided, the safety of pedestrian passage can be guaranteed, the construction period of the bridge structure can be reduced, and the construction cost can be lowered. And by connecting the bridge structure to the bridge body through the installation part 4 arranged on the side of the platform 1, vehicles and pedestrians can pass normally, and the smooth connection between the bridge body and the bridge structure can be guaranteed, and the problem of insufficient installation space caused by too small a distance between the bridge structure and the bridge body can be avoided.

The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
