Description

Technical Field

[0001] This utility model relates to the field of municipal bridge construction technology, specifically to a pier protection device for municipal bridge construction. Background Technology

[0002] The bridge abutment is the connection between the bridge pier and the pile foundation. It serves to bear and distribute the load transmitted from the upper pier. After the reinforced concrete pile is cast in place in the circular pre-embedded groove, it is necessary to wait for the concrete to set before the abutment can be built. The pile reinforcement and exposed reinforcement are exposed to the outside. If it is exposed to rain or direct sunlight, this part of the structure will be corroded by rainwater or damaged by sun.

[0003] Chinese utility model patent, authorization announcement number CN219621617U, discloses a pier cap protection device for municipal bridge construction, including a foundation pit soil body. A pile column body is pre-embedded in the middle of the foundation pit soil body, and reinforcing bars are fixedly installed in the middle of the pile column body. A first bottom cover and a second bottom cover are movably installed on the top of the foundation pit soil body corresponding to the pile column body position. The first and second bottom covers are assembled by moving them to the top of the foundation pit soil body and movably inserting positioning strips into the inner wall of positioning grooves. Then, the positions of the insertion blocks and insertion grooves are aligned to complete the assembly between the first bottom cover, the second bottom cover, and the top cover. At this point, the device is successfully installed. The top cover, in conjunction with the first and second bottom covers, provides good protection for the pile column body and reinforcing bars, thereby achieving the goal of improving the protection effect.

[0004] The above solution solves the technical problems mentioned in the background technology. However, in practical applications, the above solution still has certain defects. For example, the height of the pier in bridge construction is not fixed, but is flexibly adjusted according to specific design requirements and construction conditions. The height of the protective device in the existing technology is fixed. The fixed height of the protective device cannot match the different pier heights, resulting in poor practicality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the construction of municipal bridge abutments, after the reinforced concrete piles are cast in place in the circular pre-embedded grooves, it is necessary to wait for the concrete to set before the abutment can be erected. The pile reinforcement and exposed reinforcement are exposed to the outside, and if they are exposed to rain or direct sunlight, this part of the structure will be corroded by rainwater or damaged by sun. This solution is used to protect the exposed reinforcement when constructing municipal bridges.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a protective device for the pier cap of a municipal bridge construction, including a protective device 3. The protective device 3 is installed on the top of the pile body 2 on the foundation 1, wherein the protective device 3 includes a top protective plate, a middle protective plate 5 and a bottom protective plate 6.

[0022] Specifically, such as Figure 3 As shown, the top guard plate includes a top cover 4, on which an umbrella-shaped surface 401 is formed. The umbrella-shaped surface 401 is inclined downward at an angle of 15° to guide rainwater and falling objects. An annular extension plate 402 is provided at the bottom of the top cover 4. An elastic protective member 12 is connected to the bottom of the extension plate 402. In this solution, in order to reduce the overall weight of the top guard plate, the elastic protective member 12 is a corrugated rubber elastic plate with an elongation greater than 150%, thereby giving it good impact resistance and deformation recovery ability. The bottom end of the elastic protective member 12 is fixed to the top end of the middle guard plate 5.

[0023] An adjusting member is provided between the extension plate 402 and the middle guard plate 5, and the height of the elastic protective member 12 is adjusted by the adjusting member.

[0024] like Figure 2 and Figure 3 As shown, the adjusting component includes an adjusting screw 10 that is movably inserted into the middle guard plate 5. A support nut 11 is screwed onto the adjusting screw 10 located at the top of the middle guard plate 5. Specifically, when adjusting the distance between the top cover 4 and the ground, the adjusting screw 10 is pushed upward. When the distance between the top cover 4 and the ground reaches the set position, the support nut 11 is rotated until the bottom end face of the support nut 11 contacts the top end face of the middle guard plate 5.

[0025] In addition, to facilitate the disassembly and assembly of the middle guard plate 5 and the bottom guard plate 6, and thus facilitate the transportation of the protective device 3, the middle guard plate 5 and the bottom guard plate 6 are fixed together by several bolts 9.

[0026] In addition, to prevent rainwater from entering the interior of the protective device 3, a covering membrane 7 is fixed to the outside of the bottom protective plate 6, and a counterweight ring 8 is placed on top of the covering membrane 7. In this way, the counterweight ring 8 keeps the covering membrane 7 in close contact with the foundation 1, reducing rainwater infiltration.

[0027] As a supplement to this scheme, during installation, the bottom protective plate 6 is fitted onto the outside of the pile body 2, and then the counterweight pressure ring 8 is fitted onto the outside of the pile body 2, with the counterweight pressure ring 8 pressing on the top of the covering film 7. The worker measures the distance between the top steel bar of the pile body 2 and the top of the bottom protective plate 6. Based on this distance, the worker pulls the top cover 4 and the middle protective plate 5 to both sides until the elastic protective member 12 reaches the set height. The worker rotates the support nut 11 until the bottom end face of the support nut 11 contacts the top end face of the middle protective plate 5. Finally, the worker fits the top cover 4 onto the top of the pile body 2 and fixes the middle protective plate 5 and the bottom protective plate 6 with bolts 9.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
