Description

Technical Field

[0001] This utility model relates to the field of bridge pier technology, and more specifically, to a prefabricated pier assembly structure for bridge piers. Background Technology

[0002] As a crucial component of bridges, bridge piers' appearance design and quality management have a profound impact on the overall stability of the bridge. Strengthening the quality management of bridge pier appearance construction requires addressing issues such as raw material management, construction personnel management, and construction process management. Corresponding solutions should be developed to address problems like pitting, bubbles, honeycombing, and watermarks, ensuring that the appearance of bridge piers meets basic requirements. Currently, precast piers offer advantages such as rapid construction, reliable quality, durability, and environmental friendliness, reducing the disruption to traffic and residents' lives caused by urban construction. They are widely used in the construction of high bridge piers, directly assembled during construction.

[0003] In the current use of precast pier assembly structures, the most common method is to use L-shaped limiting plates to limit and fix the four corners of the pier. During installation, a crane is needed to lift the pier so that the pre-drilled holes at the bottom of the pier can be precisely aligned with the reinforcing bars on the foundation and then plugged in for fixation. Cement is then poured to complete the connection. However, in the alignment process, the pier must fit tightly against the inner wall of the L-shaped limiting plate to achieve precise positioning. This places extremely high demands on the crane operator's skills. Due to the complex construction site environment, the large size and heavy weight of the pier, and the limited operating space, the operator often needs to make multiple fine adjustments to get the pier to the ideal installation position. This not only prolongs the construction time and reduces construction efficiency, but also increases the error rate due to the multiple adjustments. If the crane operator makes a slight mistake, the pier may shake or collapse, which could easily lead to a safety accident and pose a significant safety hazard.

[0004] Therefore, we have made improvements to this and proposed a prefabricated pier assembly structure for high bridge piers. Utility Model Content

[0005] The purpose of this utility model is to address the existing prefabricated pier assembly structure used for high bridge piers.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Precast pier assembly structures for high bridge piers are used to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The system includes: a casting platform, with an installation groove at the center of its top, and multiple reinforcing ribs installed at the bottom of the installation groove; a pier body, which is placed inside the installation groove, with multiple interlocking holes at its bottom that mate with the reinforcing ribs; and a connecting seat, installed above the casting platform, with a slot of the same size as the installation groove at the center of its top, and four right-angled trapezoidal limiting blocks symmetrically mounted on the top of the connecting seat to mate with the pier body, the four right-angled trapezoidal limiting blocks being arranged in a circular array around the slot, and four limiting components symmetrically mounted on the top of the connecting seat to mate with the pier body, the four limiting components being located at the four corners of the slot.

[0010] As a preferred embodiment of the precast pier assembly structure for bridge piers provided by this utility model, the top of the casting platform is provided with multiple threaded holes on the periphery of the installation groove, and the top of the connecting seat is threaded with connecting bolts at the four corners. A washer is provided between the connecting bolt and the connecting seat, and the connecting bolt is threadedly engaged with the threaded hole.

[0011] To achieve the above technical solution, the casting platform and the connecting seat are connected by connecting bolts and threaded holes, and a gasket is placed between the connecting bolts and the connecting seat. This connection method effectively enhances the stability of the connection between the two and reduces the problem of loosening during assembly.

[0012] As a preferred embodiment of the prefabricated pier assembly structure for bridge piers provided by this utility model, the pier body is provided with grouting holes that communicate with the reinforcing bars.

[0013] To achieve the above technical solution, grout is injected into the gap between the reinforcing bar and the insertion hole through the grouting hole on the pier body. After the grout solidifies, the reinforcing bar and the pier body form an integral whole.

[0014] As a preferred embodiment of the prefabricated pier assembly structure for bridge piers provided by this utility model, a plurality of ball bearings are rotatably fitted on the inclined surface of the right-angled trapezoidal limiting block, and the ball bearings cooperate with the pier body. A plurality of rotating rollers are rotatably fitted on the side of the right-angled trapezoidal limiting block near the groove, and the rotating rollers cooperate with the pier body.

[0015] To achieve the above technical solution, the right-angled trapezoidal limiting block and the ball bearings on its inclined surface, along with the rotating roller near the groove opening, play a good guiding role and reduce friction during the installation of the pier body, making it easier to position the pier body in the installation groove.

[0016] As a preferred embodiment of the precast pier assembly structure for high bridge piers provided by this utility model, the limiting component includes a housing installed on the top of the connecting seat. The top of the housing has a circular groove, and the bottom of the inner cavity of the circular groove is equipped with an electric telescopic rod. The output end of the electric telescopic rod is equipped with a limiting member. The housing is provided with two square sliding grooves, and square sliders are slidably fitted in both square sliding grooves. The top of the square sliders is equipped with a connecting block that is slidably connected to the housing. The top of the connecting block is fixedly connected to the limiting member. A support plate is installed on the side of the housing away from the groove opening, and the bottom of the support plate is fixedly connected to the connecting seat.

[0017] To achieve the above technical solution, the electric telescopic rod in the limiting component can adjust the position of the limiting component according to the height of the pier body, thereby flexibly limiting the pier body.

[0018] As a preferred embodiment of the precast pier assembly structure for bridge piers provided by this utility model, the side of the limiting member near the groove is equipped with an elastic pad.

[0019] To achieve the above technical solution, the elastic pad on the side of the limiting component can not only reduce the damage to the pier body during the limiting process, but also enhance the limiting effect and improve the stability of the pier body during use.

This facilitates the positioning of the pier body within the installation groove, reduces the skill requirements for the crane operator, and improves construction efficiency. The limiting components allow for flexible positioning of pier bodies of different heights. Attached Figure Description

[0040] Please refer to Figure 1-3 The top of the casting platform 1 has multiple threaded holes 13 around the mounting groove 11. The top of the connecting seat 2 is threaded with connecting bolts 3 at the four corners. A washer 31 is placed between the connecting bolt 3 and the connecting seat 2. The connecting bolt 3 and the threaded hole 13 are threadedly engaged. The casting platform 1 and the connecting seat 2 are connected by the connecting bolt 3 and the threaded hole 13, and the washer 31 is placed between the connecting bolt 3 and the connecting seat 2. This connection method effectively enhances the connection stability between the two and reduces the problem of loosening during the assembly process.

[0041] Please refer to Figure 1-7 The pier body 6 has a grouting hole 62 that is connected to the reinforcing rib 12. Grout is injected into the gap between the reinforcing rib 12 and the insertion hole 61 through the grouting hole 62 on the pier body 6. After the grout solidifies, the reinforcing rib 12 and the pier body 6 form a whole, making the entire assembly structure more stable.

[0042] Please refer to Figure 1 and Figure 4 Multiple ball bearings 41 are rotatably fitted on the inclined surface of the right-angled trapezoidal limiting block 4. The ball bearings 41 cooperate with the pier body 6. Multiple rotating rollers 42 are rotatably fitted on the side of the right-angled trapezoidal limiting block 4 near the groove 21. The rotating rollers 42 cooperate with the pier body 6. Through the right-angled trapezoidal limiting block 4, the ball bearings 41 on its inclined surface, and the rotating rollers 42 near the groove, a good guiding effect and friction reduction are achieved during the installation of the pier body 6, making it easier to position the pier body 6 in the installation groove 11 and improving construction efficiency.

[0043] Please refer to Figure 1-7 The limiting component 5 includes a housing 501 mounted on the top of the connecting seat 2. A circular groove 502 is provided on the top of the housing 501. An electric telescopic rod 503 is installed at the bottom of the inner cavity of the circular groove 502. A limiting member 507 is installed at the output end of the electric telescopic rod 503. Two square sliding grooves 504 are provided inside the housing 501. A square slider 505 is slidably fitted in each of the two square sliding grooves 504. A connecting block 506 is installed on the top of the square slider 505 and is slidably connected to the housing 501. The top of the connecting block 506 is fixedly connected to the limiting member 507. A support plate 508 is installed on the side of the housing 501 away from the groove 21. The bottom of the support plate 508 is fixedly connected to the connecting seat 2. The electric telescopic rod 503 in the limiting component 5 can adjust the position of the limiting member 507 according to the height of the pier body 6, so as to flexibly limit the pier body 6.

[0044] Please refer to Figure 1-6 An elastic pad is installed on the side of the limiting component 507 near the groove 21; the elastic pad on the side of the limiting component 507 can not only reduce the damage to the pier body 6 during the limiting process, but also enhance the limiting effect and improve the stability of the pier body 6 during use.

[0045] Specifically, the connecting seat 2 is threadedly connected to the threaded hole 13 on the top of the casting platform 1 located around the installation groove 11 via the connecting bolt 3. A washer 31 is placed between the connecting bolt 3 and the connecting seat 2 to enhance the connection stability. A crane is used to lift the pier body 6 above the installation groove 11 and lower it slowly. During the descent, the right-angled trapezoidal limiting blocks 4, which are arranged in a circular array around the groove 21 on the connecting seat 2, play their role. The ball bearings 41 on their inclined surfaces and the rotating rollers 42 near the groove 21 contact the pier body 6, guiding the pier body 6 so that the interlocking hole 61 at the bottom of the pier body 6 can be accurately aligned with the reinforcing rib 12 in the installation groove 11 on the casting platform 1 and inserted, thus achieving the initial positioning of the pier body 6. When further limiting of the pier body 6 is required, the crane is activated according to the height of the pier body 6. The electric telescopic rod 503 in the limiting component 5 pushes the limiting component 507 to a suitable height. The limiting component 507 and the housing 501 limit the four corners of the pier body 6. During the movement of the limiting component 507, the square slider 505 slides in the square groove 504. The connecting block 506 moves with the square slider 505 and is fixedly connected to the limiting component 507, improving the stability of the limiting component 507 during movement. The elastic pad on the side of the limiting component 507 contacts the pier body 6, which not only reduces the damage to the pier during the limiting process, but also enhances the limiting effect. Finally, grout is injected into the gap between the reinforcing rib 12 and the insertion hole 61 through the grouting hole 62 on the pier body 6. After the grout solidifies, the reinforcing rib 12 and the pier body 6 form a whole, making the entire assembly structure more stable.
