[0004] Using the above connection method, after the sound barrier is installed, the bolts used to connect the columns and the bridge will be separated by the sound barrier and located on the inner and outer sides of the sound barrier respectively. During later maintenance, due to the obstruction of the sound barrier, the bolts located on the outer side of the sound barrier cannot be directly contacted. Maintenance personnel need to go around to the outer side of the sound barrier. In scenarios such as overpasses where there is no maintenance access, it is even necessary to set up temporary facilities and manually climb to the outer side of the sound barrier, which poses problems such as difficult maintenance, low maintenance efficiency, and high operational risks.

[0005] Therefore, how to reduce the difficulty of maintenance at the connection points of the sound barrier columns, improve maintenance efficiency, and reduce operational risks has become an important issue that urgently needs to be addressed. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] To better understand the bridge sound barrier column connection structure provided in this utility model embodiment, its application background is first introduced. In order to reduce the impact of traffic noise on the surrounding environment, sound barriers are widely used in highway, railway and urban rail transit bridges.

[0025] Existing sound barrier structures typically use H-shaped steel columns as the main supporting components. The bottom of the H-shaped steel columns is fixed to the bridge by bolts located on both sides. After the sound barrier is installed, the bolts used to connect the columns and the bridge are separated by the sound barrier and located on the inner and outer sides of the sound barrier. During later maintenance, due to the obstruction of the sound barrier, the bolts located on the outer side of the sound barrier cannot be directly accessed. Maintenance personnel need to go around to the outer side of the sound barrier. In scenarios such as elevated bridges where there is no maintenance access, it is even necessary to set up temporary facilities and manually climb to the outer side of the sound barrier, which presents problems such as difficult maintenance, low maintenance efficiency, and high operational risks.

[0026] Therefore, how to reduce the difficulty of maintenance at the connection points of the sound barrier columns, improve maintenance efficiency, and reduce operational risks has become an important issue that urgently needs to be addressed.

[0027] In light of the above application context, this utility model provides a bridge sound barrier column connection structure that can effectively reduce maintenance difficulty, improve maintenance efficiency, and reduce operational risks.

[0028] The following is combined with Figures 1-2 This invention describes the bridge sound barrier column connection structure.

[0029] Reference Figure 1 and Figure 2 A bridge sound barrier column connection structure includes a bridge body 100, a shield 110, a vertical wall 120, an embedded part 130, and a column 200. The shield 110 is located on the side of the bridge body 100, and its inner side forms a post-cast area with the bridge body 100. The vertical wall 120 is formed within the post-cast area, making the bridge body 100, shield 110, and vertical wall 120 a foundation for an integral structure. The embedded part 130 is embedded in the foundation, and its end protrudes from the top surface of the foundation, forming a connection end. The column 200 is located on the other side of the connection end opposite to the vertical wall 120, and the bottom of the column 200 is fixedly connected to the connection end.

[0030] In practical applications, the embedded part 130 is embedded in the foundation of the integral structure consisting of the bridge body 100, the shield 110, and the vertical wall 120. The end of the embedded part 130 protrudes from the top surface of the foundation to form a connection end, which is used to provide a connection point for the column 200. The column 200 is located on the other side of the connection end relative to the vertical wall 120. This allows the connection end to be located in an accessible position inside the sound barrier after the sound barrier is installed on the column 200. Later, the staff can only inspect and maintain the connection between the column 200 and the connection end from inside the sound barrier, without having to go around or even climb to the outside of the sound barrier. This effectively reduces the difficulty of maintenance, improves the efficiency of maintenance, and reduces the operational risk.

[0031] In one embodiment of this utility model, in order to ensure the structural stability of the embedded part 130 and to achieve effective positioning of the embedded part 130 before pouring the vertical wall 120, one side of the embedded part 130 is embedded in the shielding plate 110 and the other side is embedded in the vertical wall 120.

[0032] Specifically, during the prefabrication of the shield 110, one side of the embedded part 130 can be embedded in the shield 110, while the other side is exposed outside the shield 110 for splicing with the bridge body 100 to form the post-cast area. After the shield 110 is spliced ​​with the bridge body 100, the side of the embedded part 130 exposed outside the shield 110 is automatically positioned in the post-cast area. Then, the vertical wall 120 is poured. After the pouring is completed, the side of the embedded part 130 exposed outside the shield 110 can be embedded in the vertical wall 120, so that one side of the embedded part 130 is embedded in the shield 110 and the other side is embedded in the vertical wall 120, thus ensuring the structural stability of the embedded part 130.

[0033] It should be noted that the shield 110 is a prefabricated component installed on the outside of the railway or highway box girder (simply supported box girder). It mainly serves as the outer baffle of the box girder and is assembled together with prefabricated components such as the protective wall and vertical wall 120 to form a closed or semi-closed structure of the box girder bridge deck, forming the supporting foundation for bridge deck ancillary facilities (such as sidewalks, pipeline channels, etc.).

[0034] As a mature existing reinforced concrete precast component, this embodiment of the invention does not change the overall structural form of the cover plate 110. Instead, it embeds one side of the embedded part 130 into the cover plate 110 during precasting. Therefore, the specific structural form of the cover plate 110 can be referenced from existing technology, and will not be elaborated upon in this embodiment. Furthermore, the pre-embedding of components in reinforced concrete structures is an existing and mature process. Those skilled in the art can easily embed one side of the embedded part 130 into the cover plate 110 during precasting according to existing techniques.

[0035] It should be further explained here that, as precast reinforced concrete components, both the shield 110 and the bridge body 100 have exposed reinforcing bars. When splicing, the exposed reinforcing bars of both can be fixed by welding or other methods to achieve pre-fixation, so as to facilitate the subsequent pouring of the vertical wall 120.

[0036] In one embodiment of this utility model, a connecting plate 210 is fixedly connected to the bottom of the column 200, and a leveling layer 140 is provided on the top surface of the foundation. The connecting plate 210 and the leveling layer 140 are attached together and connected to the connecting end. This arrangement, by providing the leveling layer 140, ensures the flatness of the top surface of the foundation, keeping different columns 200 at the same height. Furthermore, the mutually attached connecting plate 210 and leveling layer 140 ensure the verticality of the column 200, while increasing the contact area between the bottom of the column 200 and the foundation, thus ensuring the stability of the column 200.

[0037] In some optional embodiments, the connecting plate 210 can be welded to the bottom of the column 200, connected to the column 200 by bolts or other connecting components, or integrally formed with the column 200. The specific connection method between the connecting plate 210 and the column 200 can be flexibly selected according to actual needs, and no specific limitations are imposed in this embodiment of the utility model.

[0038] In one embodiment of this utility model, the leveling layer 140 can be formed by post-cast gravity mortar.

[0039] In one embodiment of this utility model, multiple embedded parts 130 are provided, and the multiple embedded parts 130 are used to fix different parts of the connecting plate 210 respectively, thereby ensuring the stability of the column 200.

[0040] The bridge sound barrier column connection structure also includes an embedded plate 150, one side of which is embedded in the shield 110 and the other side is embedded in the vertical wall 120. Multiple embedded parts 130 are inserted through the embedded plate 150. In this way, the different embedded parts 130 can be connected into a whole through the embedded plate 150, thereby further improving the structural stability of the embedded parts 130.

[0041] It should be noted that the embedding method of the embedded plate 150 in the cover plate 110 is similar to that of the embedded part 130. Both are embedded in the cover plate 110 by one side of the embedded plate 150 according to the existing process when the cover plate 110 is prefabricated.

[0042] Specifically, the embedded plate 150 is made of steel plate.

[0043] In some alternative embodiments, the embedded part 130 can be an anchor bolt or a U-bolt, which can be selected according to actual needs.

[0044] In one embodiment of this utility model, the embedded part 130 is a U-bolt. The two sides of the U-bolt are respectively embedded in the cover plate 110 and the vertical wall 120, and the two threaded ends of the U-bolt protrude from the top surfaces of the cover plate 110 and the vertical wall 120, thus forming the aforementioned connecting end. The column 200 is locked to the connecting end by the first nut 160. With this configuration, when installing the column 200, the connecting plate 210 at the bottom of the column 200 is attached to the leveling layer 140, and the connecting end passes through the connecting plate 210 and is locked by the first nut 160, thereby achieving the connection and fixation of the column 200 on the aforementioned foundation.

[0045] In one embodiment of this utility model, an anti-loosening washer 161, such as a spring washer or a locking washer, is provided between the first nut 160 and the connecting plate 210. The specific type of anti-loosening washer 161 can be selected according to actual needs, and no specific limitation is made in this embodiment of the utility model.

[0046] In one embodiment of this utility model, a locking nut 162 is threaded onto the U-bolt, and the locking nut 162 abuts against the first nut 160 to prevent the first nut 160 from loosening.

[0047] In one embodiment of this utility model, an elastic washer 170 is embedded in the leveling layer 140. The elastic washer 170 is sleeved on the embedded part 130, and its upper surface is not lower than the upper surface of the leveling layer 140. With this arrangement, the elastic washer 170 can disperse the pressure between the connecting plate 210 and the leveling layer 140, reducing the problem of damage to the contact surface of the leveling layer 140 and the connecting plate 210 due to stress.

[0048] Specifically, a support member 171 is connected to the embedded part 130, and the support member 171 supports the bottom of the elastic washer 170. In this configuration, the support member 171 can provide positioning for the elastic washer 170 when the leveling layer 140 is poured.

[0049] Specifically, the support 171 can be connected to the embedded part 130 by a second nut.

[0050] In one embodiment of this utility model, a stiffening plate 220 is provided between the column 200 and the connecting plate 210, and the two adjacent sides of the stiffening plate 220 are fixedly connected to the column 200 and the connecting plate 210, respectively. The stiffening plate 220 can improve the connection strength between the column 200 and the stiffening plate 220, and ensure the connection stability of the column 200.

[0051] It is understood that, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0052] With the bridge sound barrier column connection structure provided by this utility model embodiment, in actual construction, the embedded part 130 is embedded in the foundation of the integral structure composed of the bridge body 100, the shield 110 and the vertical wall 120, and the end of the embedded part 130 protrudes from the top surface of the foundation to form a connection end, which is used to provide a connection point for the column 200. The column 200 is located on the other side of the connection end relative to the vertical wall 120, so that after the sound barrier is installed on the column 200, the connection end is located in a position that can be reached inside the sound barrier. Later, the staff only need to inspect and maintain the connection part between the column 200 and the connection end from inside the sound barrier, without having to detour or even climb to the outside of the sound barrier, which effectively reduces the difficulty of inspection, improves the efficiency of inspection, and reduces the operational risk.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
