[0024] Embodiment 1: In view of the technical problem that the protective column 2 is prone to be installed incorrectly during construction, resulting in low construction efficiency, referring to Figure 1The embodiment of the present disclosure provides a landscape bridge adopting a UHPC combined trestle plate, which comprises a bridge body 1, a protective column 2 and a connecting assembly 3, the bridge body 1 comprises a metal substrate layer 11 and an ultrahigh-strength concrete layer 12 poured above the metal substrate layer 11, the connecting assembly 3 is arranged on the surface of the metal substrate layer 11 at intervals, the protective column 2 is clamped and arranged in the connecting assembly 3, the connecting assembly 3 comprises a lower base body 32 and an upper base body 31, the lower base body 32 is fixedly arranged on the surface of the metal substrate layer 11, the upper base body 31 is sleeved on the surface of the protective column 2, the upper base body 31 and the lower base body 32 are non-permanently fixedly connected, the lower recess 33 is arranged on the surface of the lower base body 32, and the embedded part 34 protrudes from the surface of the upper base body 31 and is inserted into the lower recess 33 of the lower base body 32.

[0025] It should be noted that, in the embodiment of the present disclosure, the metal substrate layer 11 and the ultrahigh-strength concrete layer 12 poured above the metal substrate layer 11 are combined to form the trestle plate, so that the structural strength of the landscape bridge is improved.

[0026] In the embodiment of the present disclosure, the lower recess 33 and the embedded part 34 are square structures matched with each other, the embedded part 34 in the square structure can be inserted into the lower recess 33 in the square structure matched with the embedded part 34, so as to be clamped. The connecting body 36 adopts a bolt, the upper base body 31 and the lower base body 32 are provided with threaded holes matched with each other around, and the bolt is arranged in the threaded hole, so that the stability of the connection between the upper base body 31 and the lower base body 32 is improved.

[0027] When the metal substrate layer 11 is installed but the concrete is not poured, the upper base body 31 is sleeved on the surface of the protective column 2, then the upper base body 31 is inserted into the lower base body 32 on the surface of the metal substrate, so that the lower base body 32 supports the protective column 2, and the embedded part 34 in the upper base body 31 is inserted into the lower recess 33 of the lower base body 32 for fixation, then the connecting piece is passed through the upper base body 31 and the lower base body 32, so that the upper base body 31 and the lower base body 32 are fixedly connected and stably support the protective column 2, the protective column 2 is prevented from falling or tilting, and the overall construction speed is improved and the construction difficulty is reduced.

[0028] It should be noted that the upper base body 31 is sleeved on the surface of the protective column 2 in the manner of prior art, and any existing sleeving manner can be adopted, in the embodiment of the present disclosure, the structure size of the upper base body 31 is consistent with that of the protective column 2, so that the upper base body 31 can be directly sleeved, and in addition, any other sleeving means can also be adopted.

[0029] The upper base body 31 is detachably mounted with a cleaning ring 35, and the cleaning ring 35 is fixedly provided with a cleaning body 351. When the protective column 2 is placed in the upper base body 31, the protective column 2 will pass through the cleaning ring 35 and contact the cleaning body 351, so as to clean the protective column 2. In the embodiment of the present disclosure, the cleaning ring 35 is screwed, and in the daily use and maintenance cleaning after the construction of the landscape bridge is completed, the protective column 2 is difficult to be cleaned in all directions at the edge of the bridge. In the daily cleaning of the protective column 2, the cleaning ring 35 can be fixed or separated from the upper base body 31 by rotating the cleaning ring 35. After the cleaning ring 35 is rotated and separated from the upper base body 31, the protective column 2 can be cleaned in all directions by directly pulling up and down the cleaning ring 35, so as to reduce the cleaning operation difficulty and ensure that the personnel safely clean the protective column 2 in all directions.

[0030] In the embodiment of the present disclosure, the cleaning body 351 adopts a brush. The surface of the protective column 2 can be cleaned by the brush, so as to ensure the neatness of the surface of the protective column 2 and avoid damaging the appearance of the surface of the protective column 2.

[0031] In the construction process, before pouring the super-high-strength concrete, the construction personnel first insert the embedded part 34 in the upper base body 31 into the lower recessed part 33 of the lower base body 32 for fixation, then fix the connecting piece through the upper base body 31 and the lower base body 32, and then pass the protective column 2 through the upper base body 31 and contact the lower base body 32. The protective column 2 is supported by the clamping installation of the upper base body 31 and the lower base body 32, so as to prevent the protective column 2 from falling or tilting, thereby improving the overall construction speed and reducing the construction difficulty. After the support and installation of the protective column 2 are completed, the super-high-strength concrete is poured for subsequent construction.

[0032] After pouring the super-high-strength concrete, the construction of the landscape bridge is completed, and in the daily use and maintenance cleaning, the protective column 2 is difficult to be cleaned in all directions at the edge of the bridge. In the daily cleaning of the protective column 2, the cleaning ring 35 can be fixed or separated from the upper base body 31 by rotating the cleaning ring 35. After the cleaning ring 35 is rotated and separated from the upper base body 31, the protective column 2 can be cleaned in all directions by directly pulling up and down the cleaning ring 35, so as to reduce the cleaning operation difficulty and ensure that the personnel safely clean the protective column 2 in all directions.

[0033] Embodiment 2: On the basis of embodiment 1, only the differences from embodiment 1 are described below.

[0034] See Figure 2The lower base body 32 is fixedly installed with a connecting body 36 between the lower base body 32 and the metal substrate layer 11. The connecting body 36 is arranged between the lower base body 32 and the metal substrate layer 11, so that the protective column 2 is in contact with the metal substrate layer 11, and the protective column 2 is supported by the metal substrate layer 11. On the one hand, the upper base body 31 and the lower base body 32 are sleeved at a non-end position of the protective column 2, so that the protective column 2 is better supported to prevent tilting or skewing. On the other hand, the protective column 2 is directly in contact with the metal substrate layer 11 and then the ultra-high-strength concrete is poured, so that the protective column 2 is better integrated with the bridge body 1.

[0035] During construction, before pouring the ultra-high-strength concrete, the embedded part 34 in the upper base body 31 is inserted into the lower recessed part 33 of the lower base body 32 for fixation, and then the connecting part is fixed through the upper base body 31 and the lower base body 32. Then, the protective column 2 is in contact with the metal substrate layer 11 through the upper base body 31 and the lower base body 32, so that the upper base body 31 and the lower base body 32 support the non-end part of the protective column 2, which is beneficial to improve the support performance of the protective column 2. Moreover, the protective column 2 can be directly in contact with the metal substrate layer 11 and then the ultra-high-strength concrete is poured, so that the protective column 2 is better integrated with the bridge body 1. Furthermore, while supporting the protective column 2 to improve the construction efficiency, the effect of supporting and integrally forming is more beneficial. After completing the support and installation of the protective column 2, the ultra-high-strength concrete is poured for subsequent construction.

[0036] After pouring the ultra-high-strength concrete, the landscape bridge construction is completed. During daily use, maintenance and cleaning, the protective column 2 is difficult to clean in all directions at the edge of the bridge. During the cleaning of the protective column 2, the cleaning ring 35 can be fixed or separated from the upper base body 31 by rotating the cleaning ring 35. After the cleaning ring 35 is rotated and separated from the upper base body 31, the protective column 2 can be cleaned in all directions by directly pulling up and down the cleaning ring 35, so as to reduce the cleaning operation difficulty and ensure the personnel safety to clean the protective column 2 in all directions.

[0037] Embodiment 3: Based on embodiment 2, only the differences from embodiment 2 are described below.

[0038] Reference Figure 3, the landscape bridge is different due to the influence of factors such as personnel flow, protection level, surrounding environment, design style and aesthetics of the bridge, material cost and the like, and the distance between the protection columns in the construction process is different, therefore, in order to improve the applicability, two symmetrical sliding grooves 37 are arranged on the surface of the metal substrate layer 11, and two connecting bodies 36 are slidably arranged in the sliding grooves 37. The connecting body 36 can move in the sliding groove 37, and the lower base body 32 is fixedly arranged at the end of every four adjacent connecting bodies 36, so that the position of the protection column 2 can be changed by moving the position of the connecting body 36 in the sliding groove 37 during the construction process, and the position of the protection column 2 can be adjusted at any time, so as to ensure that the interval distance of each protection column 2 is uniform. At the same time, the position of the protection column 2 can also be adjusted according to different construction requirements, which is beneficial to improve the applicability.

[0039] It should be noted that the connecting body 36 does not need to be additionally provided with a locking structure, and after the connecting body 36 is moved to the specified position by the construction personnel during the construction process, the construction personnel pours the ultra-high strength concrete on the surface of the metal substrate layer 11, and the contact between the ultra-high strength concrete and the connecting body 36 will cause resistance to movement. Under the condition that there is no excessive external force interference, for example, malicious damage to the movement by personnel, the connecting body 36 will not move.

[0040] During the construction process, before pouring the ultra-high strength concrete, the construction personnel first moves the connecting body 36 to the specified position, thereby driving the lower base body 32 to move and adjust the position of the protection column 2, so as to facilitate real-time adjustment of the position of the protection column 2 during construction, and the interval distance between each connecting body 36 and the protection column 2 is uniform, so as to ensure that the interval distance of the protection column 2 is uniform.

[0041] After the position of the connecting body 36 and the lower base body 32 is adjusted, the embedded part 34 in the upper base body 31 is inserted into the lower recessed part 33 of the lower base body 32 for fixation, and then the connecting piece is fixed through the upper base body 31 and the lower base body 32, and then the protection column 2 is in contact with the metal substrate layer 11 through the upper base body 31 and the lower base body 32, so that the upper base body 31 and the lower base body 32 support the non-end part of the protection column 2, which is beneficial to improve the support performance of the protection column 2. And it can also make the protection column 2 directly contact with the metal substrate layer 11 and then pour the ultra-high strength concrete, which can better make the protection column 2 and the bridge body 1 integrally formed. Further, while improving the construction efficiency of the protection column 2, it can also be more conducive to improving the effect of support and integral forming. After the support and installation of the protection column 2 are completed, the ultra-high strength concrete is poured for subsequent construction.

[0042] After pouring the super high-strength concrete, the landscape bridge is completed, and during the daily use, maintenance and cleaning, the protective column 2 is difficult to clean in all directions at the edge of the bridge. During the daily cleaning of the protective column 2, the cleaning ring 35 can be fixed or separated from the upper base body 31 by rotating the cleaning ring 35. After the cleaning ring 35 is rotated and separated from the upper base body 31, the protective column 2 can be cleaned in all directions by directly pulling up and down the cleaning ring 35, thereby reducing the cleaning operation difficulty and ensuring the personnel safety to clean the protective column 2 in all directions.

[0043] Example 4: On the basis of example 3, only the differences from example 3 are described below.

[0044] Referring to Figure 4 In order to improve the aesthetic appearance of the landscape bridge, special decorative patterns or structures are usually arranged on the surface structures such as the bridge deck and the protective column 2. In order to ensure that the decorative patterns or structures can be easily observed by pedestrians, the special decorative patterns need to be installed towards the specified direction during installation of the protective column 2. Therefore, in order to facilitate the adjustment of the installation angle of the protective column 2, the lower base body 32 is provided with a mounting hole 38 at the center position, the upper base body 31 is provided with a receiving hole 39 at the inner center position, the embedded part 34 is provided with external threads on the outer surface, the mounting hole 38 is provided with internal threads, and the embedded part 34 and the mounting hole 38 are threadedly connected. The protective column 2 is located in the receiving hole 39, and the receiving hole 39 is a through hole with the same structure and size as the protective column 2.

[0045] The protective column 2 is placed in the receiving hole 39, and then the embedded part 34 of the upper base body 31 is threadedly rotated and installed into the mounting hole 38 of the lower base body 32. On the one hand, the upper base body 31 can be stably installed and can stably support the protective column 2 to prevent it from falling or tilting. On the other hand, for the protective column 2 with a non-columnar structure or provided with a decorative structure, the upper base body 31 can also drive the protective column 2 to rotate by rotating the installation body when it is threadedly rotated and installed into the mounting hole 38, thereby adjusting the angle of the protective column 2 and enabling the protective column 2 to be at the optimal angle position in terms of aesthetics.

[0046] It should be noted that the protective column 2 with a non-columnar structure usually has a demand for the installation angle, and the upper base body 31 can drive the protective column 2 with a non-columnar structure to rotate through the receiving hole 39.

[0047] The embedded part 34 has a length greater than that of the mounting hole 38. The length of the upper base 31 being greater than that of the mounting hole 38 can ensure that the upper base 31 is always in a threaded engagement state when the angle of the protective column 2 is adjusted, facilitating the upper base 31 to move up and down without being separated from the internal thread of the lower base 32, and being conducive to ensuring the stability of the threaded engagement, facilitating the stable support of the upper base 31 and the protective column 2. At the same time, the upper base 31 itself can be in contact with the lower base 32 when the embedded part 34 is excessively lowered, thereby avoiding being completely embedded in the lower base 32, facilitating the disassembly and assembly of the mounting body.

[0048] It should be noted that the upper base 31 does not need to be provided with a protruding stop structure at both ends, on the one hand, facilitating the installation or disassembly of the upper base 31, and on the other hand, the embedded part 34 cannot move when it is excessively lowered or the embedded part 34 and the lower base 32 are separated from each other when the embedded part 34 is excessively raised, at which time it only needs to be re-rotated and installed.

[0049] The upper surface of the upper base 31 and the lower surface of the lower base 32 are in a wave shape structure. The wave-shaped upper base 31 and lower base 32 can increase the contact area during the pouring of ultra-high strength concrete, thereby providing more stable support for the upper base 31 and the lower base 32, and being conducive to improving the installation stability of the protective column 2.

[0050] During construction, before pouring the ultra-high strength concrete, the construction personnel first move the connecting body 36 to the designated position, thereby moving the lower base 32 to adjust the position of the protective column 2, facilitating the real-time adjustment of the position of the protective column 2 during construction, and making the distance between each connecting body 36 and the protective column 2 uniform, so as to ensure the uniform distance between the protective columns 2.

[0051] After the position of the connecting body 36 and the lower base 32 is adjusted, the upper base 31 is rotated and installed into the mounting hole 38 of the lower base 32 through the embedded part 34, and then the protective column 2 is placed into the accommodating hole 39 in the upper base 31. When the angle of the protective column 2 is adjusted, the upper base 31 is rotated, and the upper base 31 can drive the non-cylindrical and decorative protective column 2 to rotate synchronously when the upper base 31 is rotated, thereby adjusting the installation angle of the protective column 2, reducing the construction difficulty and improving the construction efficiency. During the rotation of the upper base 31, since the length of the embedded part 34 is greater than that of the mounting hole 38, the upper base 31 can stably move up and down in the mounting hole 38, thereby facilitating the stable rotation of the upper base 31 to drive the protective column 2 to rotate and adjust the angle.

[0052] After the installation angle of the guard column 2 is adjusted, the guard column 2 is in contact with the metal substrate layer 11 through the upper base body 31 and the lower base body 32, so that the upper base body 31 and the lower base body 32 support the non-end part of the guard column 2, which is beneficial to improve the support performance of the guard column 2. Moreover, the guard column 2 can be directly in contact with the metal substrate layer 11 and then casted with super high strength concrete, which can better make the guard column 2 integrally formed with the bridge body 1. Furthermore, while supporting the guard column 2 to improve the construction efficiency, it is more beneficial to improve the support and integrally formed effect. After the support installation of the guard column 2 is completed, the super high strength concrete is casted for subsequent construction.

[0053] After the super high strength concrete is casted, the landscape bridge construction is completed, and in the daily use, maintenance and cleaning, the guard column 2 is difficult to be cleaned in all directions at the bridge edge. In the daily cleaning of the guard column 2, the cleaning ring 35 can be fixed or separated from the upper base body 31 by rotating the cleaning ring 35. After the cleaning ring 35 is separated from the upper base body 31 by rotating, the guard column 2 can be cleaned in all directions by directly pulling up and down the cleaning ring 35, so as to reduce the cleaning operation difficulty and ensure that the personnel safely clean the guard column 2 in all directions.

[0054] Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
