Description

Technical Field

[0001] This application relates to the field of bridge prefabricated technology, and in particular to a column installation and reinforcement structure and construction method. Background Technology

[0002] In municipal bridge construction, the current mainstream approach is to use fully prefabricated bridge piers, employing modular assembly methods to significantly improve construction efficiency. Bridge piers consist of upper and lower piers. The assembly of the upper and lower piers involves aligning and inserting the holes at the bottom of the upper pier with the reinforcing bars at the top of the lower pier, then grouting the holes to secure the reinforcing bars to the upper pier.

[0003] During the period when the grouting material in the upper and lower column sleeves reaches its strength, the stability of the upper column is relatively poor. In severe weather conditions, strong winds can easily cause the upper column to sway, resulting in misalignment of the upper and lower columns. This affects the accuracy of the upper and lower columns and seriously endangers the safety of the bridge. Summary of the Invention

[0004] To ensure that the upper and lower columns can be accurately aligned and fixed, this application provides a column installation reinforcement structure and construction method.

[0005] Firstly, this application provides a column installation reinforcement structure, which adopts the following technical solution: A column installation reinforcement structure includes a fixing plate sleeved on the column, a clamping assembly provided on the fixing plate, the clamping assembly including a positioning disk sleeved on the column, the positioning disk being detachably connected to the fixing plate, a plurality of sliding grooves being formed on the outer side wall of the positioning disk, and clamping blocks for clamping and fixing the column being slidably disposed in the plurality of sliding grooves, and a driving assembly for driving the clamping blocks to slide in the sliding grooves being provided on the fixing plate.

[0006] By adopting the above technical solution, the driving component can drive the clamping block to move in the sliding groove, thereby enabling the clamping block to clamp the upper and lower columns, which increases the connection stability between the upper and lower columns, reduces the misalignment of the upper and lower columns, and thus ensures the overall accuracy of the bridge columns.

[0007] Preferably, the fixing plate has a receiving groove, and the driving assembly includes a first rotating disk rotatably disposed in the receiving groove. The first rotating disk is located between the positioning disk and the fixing plate. A second rotating disk is rotatably disposed on the positioning disk. A first sliding rod is fixedly connected to the bottom of a set of oppositely disposed clamping blocks, and a second sliding rod is fixedly connected to the top of another set of oppositely disposed clamping blocks. A first sliding groove for the first sliding rod to slide is provided on the first rotating disk, and a second sliding groove for the second sliding rod to slide is provided on the second rotating disk.

[0008] By adopting the above technical solution, when the first rotating disk rotates, the first sliding rod slides in the first sliding groove. Due to the limiting effect of the inner wall of the sliding groove on the clamping block, the first sliding rod moves in the first sliding groove along the opening direction of the sliding groove, thereby driving the corresponding clamping block to reciprocate in the sliding groove. The second sliding rod moves on the same principle as the first sliding rod, so that multiple clamping blocks clamp the upper column and the lower column, enhancing the connection stability between the upper column and the lower column.

[0009] Preferably, the driving assembly further includes a driving rod that simultaneously drives the first rotating disk and the second rotating disk to rotate, wherein the first rotating disk and the second rotating disk rotate in opposite directions.

[0010] By adopting the above technical solution, the drive rod can drive the first rotating disk and the second rotating disk to rotate. The rotation directions of the first rotating disk and the second rotating disk are opposite so that all the clamping blocks in the positioning disk can move synchronously toward or away from the column.

[0011] Preferably, the drive rod is provided with two threaded sections with opposite directions of rotation. The two threaded sections at both ends of the drive rod are respectively threaded to a first threaded sleeve and a second threaded sleeve. The first rotating disk is hinged to the first threaded sleeve, and the second rotating disk is hinged to the second threaded sleeve.

[0012] By adopting the above technical solution, when the drive rod rotates, the first threaded sleeve and the second threaded sleeve can move along the drive rod in a direction that is close to or far from each other, thereby driving the first rotating disk and the second rotating disk to rotate simultaneously in opposite directions, so that several clamping blocks can move synchronously toward the column to clamp the upper column and the lower column.

[0013] Preferably, a first ear plate is fixedly connected to the side wall of the first rotating disk, and a second ear plate is fixedly connected to the side wall of the second rotating disk. The first ear plate is hinged to the first threaded sleeve, and the second ear plate is hinged to the second threaded sleeve.

[0014] By adopting the above technical solution, the first ear plate and the second ear plate increase the distance between the drive rod and the positioning plate, making it less likely for the drive rod and the positioning plate to come into contact.

[0015] Preferably, a limiting ring is detachably connected to the fixing plate. The limiting ring is located above the second rotating disk, and a limiting groove for accommodating the second rotating disk is provided at the bottom of the limiting ring.

[0016] By adopting the above technical solution, the second rotating disk rotates in the limiting groove, and the inner wall of the limiting groove provides a limiting effect on the second rotating disk, reducing the possibility of the second rotating disk shifting its position when rotating.

[0017] Preferably, the fixing plate is fixedly connected to a fixing edge, and a bolt threaded onto the fixing edge is threaded onto the fixing edge and connected to the positioning plate. The side wall of the limiting ring is fixedly connected to a limiting edge aligned with the fixing edge, and the fixing edge and the limiting edge are threaded onto the same bolt.

[0018] By adopting the above technical solution, the fixing plate and the limiting ring are detachably connected to the fixing edge by bolts, which facilitates the installation and disassembly of the first rotating plate, the second rotating plate and the positioning plate.

[0019] Preferably, the bottom of the fixing plate is provided with a support assembly, the support assembly includes a support plate fixed on the ground, and a plurality of threaded screws are threadedly connected to the fixing plate. One end of each of the plurality of threaded screws passes through one end of the support plate and is connected to a drive source. The drive source is fixedly connected to the bottom of the support plate.

[0020] By adopting the above technical solution, when the drive source drives the threaded screw to rotate, the fixed plate can move back and forth on the threaded screw, which facilitates the removal, installation and positioning of the fixed plate on the column. The support plate can support the drive source and the threaded screw. When the reinforcement device fixes the upper and lower columns, the support plate and the threaded screw can provide support for the upper and lower columns, further enhancing the stability between the upper and lower columns.

[0021] Secondly, this application provides a construction method for a column installation reinforcement structure, comprising the following steps: S1. Before installing the upper column to the lower column, measure and lay out the lines to determine the installation position of the support plate and fix it. Sleeve the fixing plate on the lower column and install the threaded screw and drive source on the support plate. S2. The first rotating disk, the positioning disk, the second rotating disk and the limiting ring are successively placed on the lower column, and then the positioning disk and the limiting ring are fixed on the fixed plate. S3. Install the upper column. After installation, the drive source drives the threaded screw to rotate, so that the fixing plate moves upward on the threaded screw until the positioning plate moves to the joint between the upper column and the lower column. S4. The drive rod rotates, causing several clamping blocks to move synchronously toward the column until the column is pressed against it.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The drive component can drive the clamping block to move in the sliding groove, thereby enabling the clamping block to clamp the upper column and the lower column, which increases the connection stability between the upper column and the lower column, reduces the misalignment of the upper and lower columns, and thus ensures the overall accuracy of the bridge column. Because the clamping block is limited by the inner wall of the sliding groove, the first sliding rod moves in the first sliding groove along the opening direction of the sliding groove, thereby driving the corresponding clamping block to reciprocate in the sliding groove. The second sliding rod moves in the same way as the first sliding rod, so that multiple clamping blocks clamp the upper column and the lower column, enhancing the connection stability between the upper column and the lower column. When the drive source drives the threaded screw to rotate, the fixed plate can move back and forth on the threaded screw, which facilitates the removal, installation and positioning of the fixed plate on the column. The support plate can support the drive source and the threaded screw. When the reinforcement device fixes the upper and lower columns, the support plate and the threaded screw can provide support for the upper and lower columns, further enhancing the stability between the upper and lower columns.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a column installation reinforcement structure.

[0027] A column installation reinforcement structure, referring to Figure 1The system includes a fixing plate 2 fitted onto the lower column 12, and a reinforcement device on the fixing plate 2 for simultaneously fixing the upper column 11 and the lower column 12. The reinforcement device includes a support assembly 3 for supporting the fixing plate 2. The fixing plate 2 has several threaded holes around its perimeter, and a threaded screw 31 is threadedly connected to the inner wall of each threaded hole. The threaded screw 31 is arranged parallel to the column. The support assembly 3 includes several support plates 33 fixedly arranged around the column. There are two support plates 33, and adjacent threaded screws 31 are rotatably mounted on the same support plate 33. A drive source 32 is fixedly connected to the bottom of the support plate 33. One end of the threaded screw 31 passing through the support plate 33 is fixedly connected to the drive end of the drive source 32. The drive source 32 is a motor. When the drive source 32 drives the threaded screw 31 to rotate, the fixed plate 2 can move back and forth on the threaded screw 31, which facilitates the removal, installation and positioning of the fixed plate 2 on the column. The support plate 33 can support the drive source 32 and the threaded screw 31. When the reinforcement device fixes the upper and lower columns 12, the support plate 33 and the threaded screw 31 can provide support for the upper and lower columns 12, further enhancing the stability between the upper and lower columns 12.

[0028] Reference Figure 1 and Figure 2 The fixing plate 2 has a receiving groove 21, and the bottom of the receiving groove 21 has a through hole for the column to pass through. The reinforcement device includes a clamping assembly 4, which includes a positioning plate 41 fixed on the receiving groove 21. Several fixing edges 22 are fixedly connected to the fixing plate 2. Bolts threadedly connected to the positioning plate 41 are passed through the fixing edges 22 to fix the positioning plate 41. The positioning plate 41 has a through hole in the middle for the column to pass through.

[0029] Reference Figure 2 The positioning disk 41 has several sliding grooves 42 on its side wall, which communicate with the through holes. In this embodiment, there are four sliding grooves 42. In other embodiments, the number of sliding grooves 42 can be any number greater than three. Clamping blocks 43 are slidably disposed in the sliding grooves 42. The clamping blocks 43 span the upper column 11 and the lower column 12. The four clamping blocks 43 slide in the sliding grooves 42 and can respectively abut against the four sides of the column, thereby fixing the column.

[0030] Reference Figure 2 and Figure 3The reinforcement device also includes a drive assembly 5 that drives four clamping blocks 43 to reciprocate in the sliding groove 42. The drive assembly 5 includes a first rotating disk 51 rotatably disposed in the receiving groove 21, located between the positioning disk 41 and the fixing plate 2. Two opposing clamping blocks 43 have first sliding rods 53 fixedly connected to their bottoms. The first rotating disk 51 has a first sliding groove 511 for the first sliding rods 53 to slide in. A second rotating disk 52 is rotatably disposed on the positioning disk 41, clamping the positioning disk 41 between the first and second rotating disks 51 and 52. Two other opposing clamping blocks 43 have second sliding rods 54 fixedly connected to their tops. The second rotating disk 52 has a second sliding groove 521 for the second sliding rods 54 to slide in. The opening directions of the first and second sliding grooves 511 and 521 intersect with the opening direction of the sliding groove 42. Both the first and second rotating disks 51 and 52 have through holes for the column to pass through.

[0031] Reference Figure 1 and Figure 2 The drive assembly 5 also includes a drive rod 55 that simultaneously drives the first rotating disk 51 and the second rotating disk 52 to rotate. In this embodiment, the drive rod 55 is a threaded rod with two threaded sections with opposite directions of rotation. A first ear plate 512 is fixedly connected to the side wall of the first rotating disk 51, and a second ear plate 522 is fixedly connected to the side wall of the second rotating disk 52. The two threaded sections at both ends of the threaded rod are respectively threadedly connected to a first threaded sleeve 56 and a second threaded sleeve 57, wherein the first threaded sleeve 56 and the first ear plate 512 are hinged, and the second threaded sleeve 57 and the second ear plate 522 are hinged. A rotating head 58 is fixedly connected to the end of the drive rod 55. The rotating head 58 is rectangular, which facilitates connection to drilling equipment such as an electric drill. In other embodiments, the first ear plate 512 and the second ear plate 522 can be rotated manually.

[0032] When the drive rod 55 rotates, the first threaded sleeve 56 and the second threaded sleeve 57 can move along the drive rod 55 in directions that are closer to or further away from each other. When the first threaded sleeve 56 moves along the drive rod 55, it drives the first rotating disk 51 to rotate. When the second threaded sleeve 57 rotates, it drives the second rotating disk 52 to rotate. The rotation directions of the first rotating disk 51 and the second rotating disk 52 are opposite. When the first rotating disk 51 rotates, the first sliding rod 53 slides in the first sliding groove 511. Because the clamping block 43 is limited by the inner wall of the sliding groove 42... The first sliding rod 53 moves along the opening direction of the sliding groove 42 in the first sliding groove 511, thereby driving the corresponding clamping block 43 to reciprocate in the sliding groove 42. The second sliding rod 54 moves on the same principle as the first sliding rod 53. Through the rotation of the first rotating disk 51 and the second rotating disk 52, the four clamping blocks 43 can move simultaneously in the sliding groove 42 toward the direction of approaching or moving away from the column, so that the clamping blocks 43 can clamp the upper column 11 and the lower column 12 at the same time, thereby enhancing the connection stability between the upper column 11 and the lower column 12.

[0033] Reference Figure 1 and Figure 3 A limiting ring 6 is provided on the second rotating disk 52. A limiting edge 61 is fixedly connected to the side wall of the limiting ring 6. The limiting edge 61 and the fixed edge 22 are aligned and are fitted with the same locking bolt. A limiting groove 62 is formed on the bottom wall of the limiting ring 6, and the second rotating disk 52 is rotatably positioned within the limiting groove 62. The limiting ring 6 is fixed to the fixed edge 22, and the limiting ring 6 limits the position of the second rotating disk 52, reducing the possibility of positional deviation when the second rotating disk 52 rotates.

[0034] The implementation principle of the column installation reinforcement structure in this application embodiment is as follows: the fixing plate 2, the first rotating disk 51, the positioning disk 41, the second rotating disk 52 and the limiting ring 6 are successively sleeved on the column. The threaded rod is screwed on, so that the first threaded sleeve 56 and the second threaded sleeve 57 move towards each other. The first threaded sleeve 56 and the second threaded sleeve 57 drive the first rotating disk 51 and the second rotating disk 52 to rotate respectively, and the rotation directions of the first rotating disk 51 and the second rotating disk 52 are opposite. This drives the first sliding rod 53 to move in the first sliding groove 511 along the opening direction close to the column, and drives the second sliding rod 54 to move in the second sliding groove 521 along the opening direction close to the column. In this way, the four clamping blocks 43 clamp and fix the upper column 11 and the lower column 12, thereby improving the connection stability between the upper column 11 and the lower column 12.

[0035] This application also discloses a construction method for a column installation reinforcement structure, including the following steps: S1. Before installing the upper column 11 to the lower column 12, measure and lay out the lines to determine the installation position of the support plate 33, fix the support plate 33 around the column, put the fixing plate 2 on the lower column 12, and install the threaded screw 31 and the drive source 32 on the support plate 33. S2. The first rotating disk 51, the positioning disk 41, the second rotating disk 52 and the limiting ring 6 are successively placed on the lower column 12, and then the positioning disk 41 and the limiting ring 6 are fixed on the fixing plate 2. S3. Install the upper column 11. After installation, drive source 32 drives threaded screw 31 to rotate, so that fixing plate 2 moves up on threaded screw 31 until positioning plate 41 moves to the joint between upper column 11 and lower column 12. S4, the drive rod 55 rotates, causing several clamping blocks 43 to move synchronously toward the column until the column is pressed against it.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
