[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0027] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] This utility model discloses a concrete bridge curing and prestressing tensioning platform 100, comprising a foundation frame 1, jacks 2, and spray pipes (not shown). The foundation frame 1 is vertically mounted on the ground and includes multiple foundation columns 3. Adjacent foundation columns 3 are connected by a first connecting part 4 perpendicular to the foundation columns 3. A horizontal beam 5 is erected on the side of each foundation column 3 away from the ground, arranged horizontally along a first direction. A longitudinal beam 6 is erected between adjacent horizontal beams 5 in a second direction perpendicular to the first direction, and the longitudinal beam 6 can move along the first direction on the horizontal beams 5. Jacks 2 are located at the middle of the side of each longitudinal beam 6 away from the ground to support the concrete bridge. Spray pipes are located between adjacent horizontal beams 5 in the first direction for water curing of the concrete bridge.

[0030] When the precast concrete beams are placed on the foundation frame 1, the precast concrete bridge is precisely in its original installation position, allowing for direct curing and prestressing tensioning without occupying ground space. By configuring the longitudinal beams 6 to move relative to the transverse beams 5, the position of the precast concrete beams mounted on the jacks 2 can be adjusted, ensuring the concrete bridge remains in its original location.

[0031] In one embodiment, the concrete bridge curing and prestressing tensioning platform 100 of this utility model further includes an upper frame 7. The upper frame 7 is erected at the end of the foundation frame 1 away from the ground. The upper frame 7 includes multiple upper columns 8, each upper column 8 corresponding to a foundation column 3, and adjacent upper columns 8 are connected by a second connecting part 9 perpendicular to the upper column 8. A crossbeam 5 is erected at the end of the upper column 8 away from the ground. When the height of the foundation column 3 is insufficient, preventing the concrete bridge from reaching its original height, the upper frame 7 is added to the foundation frame 1 to allow the height of the precast concrete beam to reach its original height. The upper frame 7 can be a single unit or multiple units arranged sequentially in the vertical direction.

[0032] In one embodiment, each foundation post 3 is a column with a preset diameter. Because the column itself has a relatively large diameter, it is more stable when installed on the ground. In another embodiment, such as... Figure 1 As shown, each foundation column 3 includes four vertically arranged first columns 31 forming a square. The first connecting part 4 connects two adjacent foundation columns 3 and two adjacent first columns 31 within the same foundation column 3. By setting the foundation column 3 into a square formed by four first columns 31, each foundation column 3 is stably installed on the ground.

[0033] Accordingly, in one embodiment, each upper column 8 includes two vertically arranged second columns 81. The second connecting portion 9 connects two adjacent upper columns 8 and two second columns 81 within the same upper column 8. By configuring the upper column 8 to consist of two second columns 81, the second columns 81 become more stable, and the number of second columns 81 is less than the number of first columns 31, reducing the overall structural weight of the platform and making the platform structure more stable after installation. In other embodiments, each upper column 8 includes four second columns 81, and the second columns 81 correspond to the first columns 31.

[0034] In one embodiment, a transfer beam 10 is provided at the end of two adjacent first columns 31 on the same foundation column 3 that is away from the ground, and two second columns 81 are supported in the middle of the two parallel transfer beams 10. Through the above arrangement, the center of gravity of the upper frame 7 coincides with the center of gravity of the foundation frame 1, making the overall structure of the platform more stable.

[0035] In one embodiment, the upper column 8 further includes a third connecting part 11, which connects two second columns 81 in the same upper column 8. By providing the third connecting part 11, the stability of the upper frame 7 structure is enhanced.

[0036] In one embodiment, a fence 12 is provided on the outer periphery of the longitudinal beam 6. When maintenance personnel need to repair the jack 2, the fence 12 can ensure the safety of the maintenance personnel.

[0037] In one embodiment, a connecting bridge (not shown) is provided between two adjacent crossbeams 5 in the first direction for maintenance personnel to pass through. This facilitates maintenance personnel access from one side to the other.

[0038] In one embodiment, a roller (not shown) is provided at the end of the foundation column 3 near the ground. By providing the roller, the position of the concrete bridge curing and prestressing tensioning platform 100 of this utility model relative to the ground can be adjusted so that the precast concrete beam is in its original position.

[0039] The concrete bridge maintenance and prestressing tensioning platform 100 of this utility model also includes a slide rail (not shown) fixed on the ground and cooperating with rollers. The rollers move on the slide rail, making the movement of the platform more stable.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
