Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge support anchoring, in particular to an adjustable anchoring device for bridge support. BACKGROUND

[0002] The bridge support is a key component connecting the upper structure and the lower structure of the bridge, and its main function is to safely and reliably transmit the load of the upper structure (including dead load and live load) to the lower structure, and to adapt to the displacement (such as expansion and rotation) of the upper structure caused by factors such as load, temperature change, concrete shrinkage and creep, so as to ensure the normal work and durability of the bridge structure.

[0003] According to the search, the patent with the publication number CN118621681A discloses an adjustable anchoring device for bridge support, which comprises a lower steel plate, a rubber pad, an upper steel plate, an adjusting assembly, a quick-release assembly and a reinforcing assembly. The adjusting assembly is designed to not only anchor the bridge support with the upper structure and the lower structure, but also provide certain longitudinal support force perpendicular to the horizontal plane, and the size of the support area can be adjusted, which greatly improves the stress range of the bridge support and the stability of the support. The quick-release assembly can realize quick installation and disassembly of the anchor rod, which greatly improves the construction efficiency and facilitates the replacement of the aging support in the later period without the need to cut off the anchor rod, greatly reducing the construction difficulty. Moreover, the reinforcing assembly can also expand the stress range of the bridge support, making the load dispersion more uniform, which not only improves the load bearing performance of the bridge support, but also prolongs the service life of the bridge support and improves its durability, reducing the frequency of maintenance. However, the following problems still exist when the scheme is actually used: In the installation and construction of the bridge pot-type rubber support, the connection and fixation of the bottom anchor rod with the bottom groove of the bridge base is a key link to ensure the overall stability of the support, which must be anchored through subsequent concrete pouring. However, due to the smooth metal surface of the anchor rod, it is easy to be disturbed by various external factors and produce unnecessary displacement in the dynamic process of concrete pouring. This displacement not only directly destroys the accuracy of the support installation, causing deviation of the support positioning and design parameters, but also may change the stress state of the anchor rod, causing local stress concentration and affecting the effective transmission of the load of the upper structure by the support. SUMMARY

[0004] The technical problem to be solved by the present application is that in the prior art, the installation of the bottom anchor rod of the bridge pot-type rubber support is a key to stability, which needs to be anchored through concrete pouring, but due to the smooth surface of the anchor rod, it is easy to produce displacement under the influence of concrete impact, formwork deformation and personnel touch during pouring, which destroys the installation accuracy, causes positioning deviation and stress concentration, and affects the load transmission. Therefore, we propose an adjustable anchoring device for bridge support.

In the present application, when the anchor rod is deeply inserted into the bottom groove, the support foot cap drives the reinforcing cylinder to rotate out and become horizontal, and the hemispherical cover is pushed to extend the fastening rod after being pressed, so that the reinforcing cylinder and the fastening rod increase the contact area with the concrete, thereby improving the overall stability of the support, and at the same time, these components abut against the inner wall of the bottom groove, which can effectively reduce the displacement of the anchor rod under external forces such as concrete pouring, thereby ensuring the accurate installation position of the support and reducing the safety hazards caused by displacement.

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figures 1-4 As shown, the present invention provides a technical solution: an adjustable anchoring device for bridge bearings, including a base plate 11 and a bottom basin 13 fixedly installed on the top surface of the base plate 11. A top plate 12 is provided at the top of the bottom basin 13. Embedded rods 14 are provided at the four corners of the top plate 12. Anchor rods 15 are fixedly installed at the four corners of the base plate 11. A support component is provided on the inner side of the bottom basin 13. The support assembly includes a rubber plate 22 fixedly installed on the bottom surface of the basin 13. A fixing steel plate 31 is fixedly installed on the inner wall of the basin 13 at the top of the rubber plate 22. The rubber plate 22 is made of polytetrafluoroethylene. Several evenly distributed openings 23 are opened on the top surface of the rubber plate 22. A retaining ring 25 corresponding to the rubber plate 22 is fixedly installed on the inner wall of the basin 13. A retaining groove 24 adapted to the retaining ring 25 is opened on the outer wall of the rubber plate 22. The cross-sectional shape of the retaining ring 25 and the retaining groove 24 are both semi-circular.

[0020] In use, firstly, for the top plate 12, the construction personnel need to connect the top plate 12 to the main body of the bridge through the embedded rod 14. During the prefabrication of the main body of the bridge, the embedded rod 14 is tied to the bridge steel bars and transported to the construction site with the main body of the bridge and then hoisted. When hoisting the main body of the bridge to the position of the bridge base, the construction personnel need to connect the bottom plate 11 and the top plate 12. When connecting, the bottom basin 13 on the bottom plate 11 can be aligned with the top plate 12 and fixed with bolts, thus completing the installation of the bottom plate 11, the bottom basin 13 and the top plate 12.

[0021] Reference Figure 3 and Figure 4 As shown, the support assembly is provided with several sets of oiling structures. The oiling structure includes an oil storage cylinder 32 fixedly installed on the top surface of the fixed steel plate 31 and corresponding to the opening 23. A sealing membrane 33 is provided at the top of the oil storage cylinder 32, and an oil storage part 34 is provided on the inner side of the oil storage cylinder 32. A fixing ring 35 is fixedly installed on the inner wall of the top of the opening 23, and a plug-in sleeve 36 corresponding to the oil storage cylinder 32 is fixedly installed on the bottom surface of the fixing ring 35.

[0022] During the installation of the base basin 13 and the top plate 12, in the initial state, the sliding plate 21 in the base basin 13 protrudes slightly from the base basin 13 and is fixed in position by the engagement of the retaining ring 25 and the retaining groove 24. As the bolts are tightened, the top of the base basin 13 is pressed against the bottom surface of the top plate 12, causing the sliding plate 21 to move downwards. The retaining groove 24 moves out of the outer wall of the retaining ring 25. During the downward movement of the sliding plate 21, the insert sleeve 36 in the opening 23 on it can puncture the sealing film 33 on the oil reservoir 32, and the oil reservoir... The inner side of the oil reservoir 34 in 32 is filled with lubricating grease. As the sealing membrane 33 is punctured, the lubricating grease in the oil reservoir 34 can enter the plug sleeve 36 and be discharged through the fixing ring 35, and then reach the top surface of the slide plate 21 and the bottom surface of the top plate 12 to achieve the application of lubricating grease. There is no need for manual pre-application. This not only eliminates the separate oiling process and saves installation time, but also makes the grease distribution more uniform. It avoids the impact of uneven manual application on the sliding performance of the support, ensures smooth contact between the slide plate 21 and the top plate 12, and improves installation efficiency and quality.

[0023] ReferenceFigures 5-7 As shown, the outer wall of the anchor rod 15 has several evenly distributed openings 41. The inner side of the anchor rod 15 is provided with a retaining component. The retaining component includes a sliding seat 42 that is slidably installed on the inner wall of the bottom end of the anchor rod 15. A top rod 43 is fixedly installed on the top surface of the sliding seat 42. A reinforcing cylinder 44 is rotatably installed on the inner wall of the anchor rod 15 at the bottom end of several openings 41. A support seat 46 corresponding to the reinforcing cylinder 44 is fixedly installed on the inner bottom surface of the opening 41. A connecting telescopic rod 45 is provided between the bottom end of the reinforcing cylinder 44 and the top rod 43. The telescopic end of the connecting telescopic rod 45 is hinged to the outer wall of the reinforcing cylinder 44, and the fixed end is fixedly connected to the outer wall of the top rod 43. An adjustment component is provided at the end of the anchor rod 15 away from the base plate 11. A fastening component is provided on the reinforcing cylinder 44.

[0024] Construction workers can lower the hoisted bridge body so that the four anchor rods 15 on the base plate 11 can be inserted into the pre-reserved bottom groove on the bridge base. When the bridge body is in place on the bridge base, the four anchor rods 15 can be fully inserted into the bottom groove. At the same time, as the anchor rods 15 are inserted into the bottom groove, the sliding seat 42 and the top rod 43 can be driven to slide upward relative to the anchor rods 15 by the support rod under the action of the adjustment component. This can also drive the connecting telescopic rod 45 to move. When the connecting telescopic rod 45 moves, it can drive the reinforcing cylinder 44, so that the reinforcing cylinder 44 rotates out of the opening 41 and is in a horizontal position.

[0025] Reference Figure 5 and Figure 6 As shown, the adjustment assembly includes a connecting ball 51 fixedly mounted on the bottom surface of the sliding seat 42 by a support rod. The outer wall of the connecting ball 51 is provided with a support cap 52. The top surface of the support cap 52 is provided with a connecting ball groove 53 that is adapted to the connecting ball 51. The bottom end of the reinforcing cylinder 44 is screwed with a threaded sleeve 54. The outer diameter of the support cap 52 is the same as the outer diameter of the threaded sleeve 54.

[0026] After the base plate 11, base basin 13, and top plate 12 are installed, the construction personnel need to measure the angles of the base plate 11 and top plate 12. If the base plate 11 and top plate 12 tilt slightly due to prefabrication issues of the bridge main structure, in order to ensure stable support by contacting the bottom of the anchor rod 15 with the inner bottom surface of the trench, the construction personnel can adjust the threaded sleeve 54 by rotating it to change its position on the outer wall of the anchor rod 15. This allows the support cap 52 to move upward relative to the anchor rod 15 under pressure when the anchor rod 15 enters the trench, and then lock against the threaded sleeve 54. The support cap 52, in conjunction with the anchor rod 15, can support the base plate 11. To provide stable support, after the support cap 52 contacts the bottom groove, with the cooperation of the connecting ball 51 and the connecting ball groove 53, the bottom surface of the support cap 52 can fully contact the inner wall of the bottom groove, making the support more stable. By rotating the threaded sleeve 54, its position on the anchor rod 15 can be adjusted. With the combination of the support cap 52, the connecting ball 51, and the connecting ball groove 53, the bottom surface of the support cap 52 can fully contact and lock with the inner wall of the bottom groove. This not only solves the problem of unstable support caused by prefabrication errors, but also achieves stable support for the base plate 11 through the locking of the support cap 52 and the threaded sleeve 54, ensuring that the bottom end of the anchor rod 15 is in effective contact with the bottom surface of the bottom groove.

[0027] Reference Figure 8 and Figure 9 As shown, the fastening assembly includes a slide rod 61 slidably mounted on the inner wall of the reinforcing cylinder 44. A guide plate 62 is fixedly mounted on one end of the slide rod 61 located inside the reinforcing cylinder 44. A spring 63 is fixedly mounted between the side of the guide plate 62 and the inner wall of the reinforcing cylinder 44. A hemispherical cover 64 is fixedly mounted on one end of the slide rod 61 located outside the reinforcing cylinder 44. Several evenly distributed guide openings 71 are provided on the outer wall of the reinforcing cylinder 44. Guide sleeves 72 are fixedly mounted on the inner wall of the reinforcing cylinder 44 at the positions of several guide openings 71. A fastening rod 73 is slidably mounted on the inner wall of the guide sleeve 72. A push plate 74 adapted to the fastening rod 73 is fixedly mounted on the outer wall of the slide rod 61. A pushing part 75 is provided on one end of the push plate 74 near the fastening rod 73.

[0028] When the reinforcing cylinder 44 rotates out of the anchor rod 15, the hemispherical cover 64 at its end can abut against the inner wall of the bottom trench. Under the action of thrust, the hemispherical cover 64 can drive the guide plate 62 of the sliding rod 61 to slide and compress the spring 63. During the sliding process of the sliding rod 61, the push plate 74 on its outer wall can slide synchronously and push the fastening rod 73 in the guide sleeve 72 through the push part 75, so that the fastening rod 73 moves out of the guide port 71. The reinforcing cylinder 44 and the fastening rod 73 extending from the outer wall of the anchor rod 15 can have a larger contact area with the concrete when pouring concrete in the bottom trench, ensuring the stability of the entire support during use. At the same time, when the anchor rod 15 enters the bottom trench, through the use of the reinforcing cylinder 44, the sliding rod 61 and the hemispherical cover 64, the anchor rod 15 can be pressed tightly in the bottom trench, reducing the displacement of the anchor rod 15 under the action of external force and ensuring the accuracy of the support installation.

[0029] Working principle: When in use, firstly, for the top plate 12, the construction personnel need to connect the top plate 12 to the bridge body through the embedded rod 14. During the prefabrication of the bridge body, the embedded rod 14 is tied to the bridge reinforcement and transported to the construction site with the bridge body and then hoisted. When hoisting the bridge body to the installation position of the bridge base, the construction personnel need to connect the bottom plate 11 and the top plate 12. During the connection, the bottom basin 13 on the bottom plate 11 can be aligned with the top plate 12 and fixed with bolts to complete the installation of the bottom plate 11, bottom basin 13 and top plate 12. During the installation of the base basin 13 and the top plate 12, in the initial state, the sliding plate 21 in the base basin 13 protrudes from the base basin 13 and is fixed in position by the engagement of the retaining ring 25 and the retaining groove 24. As the bolts are tightened, the top of the base basin 13 and the bottom surface of the top plate 12 are pressed together, which can press the sliding plate 21, causing the sliding plate 21 to move downward. The retaining groove 24 moves out of the outer wall of the retaining ring 25. During the downward movement of the sliding plate 21, the insert sleeve 36 in the opening 23 on it can puncture the sealing film 33 on the oil storage cylinder 32. The inner side of the oil storage part 34 in the oil storage cylinder 32 is filled with lubricating grease. As the sealing film 33 is punctured, the lubricating grease in the oil storage part 34 can enter the insert sleeve 36 and be discharged through the fixing ring 35, and then to the area between the top surface of the sliding plate 21 and the bottom surface of the top plate 12 to achieve the application of lubricating grease. There is no need for manual application before the docking installation, which omits the process, saves the installation time of the bridge bearing, and the grease is applied more evenly. After the base plate 11, base basin 13 and top plate 12 are installed, the construction personnel need to measure the angle of the base plate 11 and top plate 12. If the base plate 11 and top plate 12 are slightly tilted due to the prefabrication of the main bridge structure, in order to ensure that the bottom end of the anchor rod 15 contacts the inner bottom surface of the bottom groove for stable support, the construction personnel can adjust the threaded sleeve 54 and rotate it to change its position on the outer wall of the anchor rod 15. When the anchor rod 15 enters the bottom groove, the support cap 52 moves upward relative to the anchor rod 15 under pressure and can abut against the threaded sleeve 54 to lock it. The support cap 52, together with the anchor rod 15, can provide stable support for the base plate 11. At the same time, after the support cap 52 contacts the bottom groove, with the cooperation of the connecting ball 51 and the connecting ball groove 53, the bottom surface of the support cap 52 can fully contact the inner wall of the bottom groove, making the support more stable. Subsequently, construction workers can lower the hoisted bridge main body, allowing the four anchor rods 15 on the base plate 11 to be inserted into the pre-reserved grooves on the bridge base. When the bridge main body is in place on the bridge base, the four anchor rods 15 can be fully inserted into the grooves. Simultaneously, as the anchor rods 15 penetrate deeper into the grooves, the support caps 52 abut against the inner wall of the groove. The support caps 52 can drive the sliding seat 42 and the top rod 43 to slide upwards relative to the anchor rods 15 via the support rods, and can also drive the connecting telescopic rod 45 to move. When the connecting telescopic rod 45 moves, it can drive the reinforcing cylinder 44, causing the reinforcing cylinder 44 to rotate out of the opening 41 and be in a horizontal position. When the reinforcing cylinder 44 rotates out of the anchor rods 15, its hemispherical cover 64 can abut against the inner wall of the groove, and under the thrust... When the hemispherical cover 64 is used, it can drive the guide plate 62 of the slide rod 61 to slide and compress the spring 63. During the sliding of the slide rod 61, the push plate 74 on its outer wall can slide synchronously, and push the fastening rod 73 in the guide sleeve 72 through the push part 75, so that the fastening rod 73 moves out of the guide port 71. The reinforcing cylinder 44 and the fastening rod 73 extending from the outer wall of the anchor rod 15 can have a larger contact area with the concrete when the concrete is poured in the bottom trench, ensuring the stability of the entire support during use. At the same time, when the anchor rod 15 enters the bottom trench, through the use of the reinforcing cylinder 44, the slide rod 61 and the hemispherical cover 64, the anchor rod 15 can be pressed tightly in the bottom trench, reducing the displacement of the anchor rod 15 under the action of external force, and ensuring the accuracy of the support installation.
