Description

Technical Field

[0001] This invention relates to an adjustable positioning device for steel structure support nodes, belonging to the field of civil engineering. Background Technology

[0002] When assembling structures such as bridges, bearings are needed for vibration damping and supporting the main load-bearing structure. During installation, a concrete structure is poured at the base of the bearing and secured with a steel structure before the bearing is installed on top of the steel structure. Depending on manufacturing errors and the bearing model, the installation position of the bearing needs adjustment. Current adjustment methods involve adjusting the position of adjustment holes. However, this method lacks a locking mechanism, which may introduce errors and affect construction quality. Summary of the Invention

[0003] To address the problem of unstable adjustment during support installation, this invention proposes an adjustable positioning device for steel structure support nodes.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: The present invention includes a concrete structure, positioning components, and an adjustment structure. Multiple positioning components are connected to the concrete structure, and an adjustment structure is connected to the positioning components. The adjustment structure includes a positioning sleeve, which is inserted into the positioning components. A horizontal control bolt is rotatably connected to the positioning sleeve, and a slider is threadedly connected to the horizontal control bolt. The slider is slidably connected to the adjustment part through a groove. A vertical control bolt is threadedly connected to the bottom end of the adjustment part, and a bottom tray is rotatably connected to the top end of the vertical control bolt. A positioning sleeve is connected to the top end of the bottom tray.

[0005] Furthermore, the positioning sleeve has a through hole at its center for inserting a positioning component, and the size of the through hole is the same as that of the positioning component.

[0006] Furthermore, the top of the adjustment part is symmetrically provided with injection holes A, and the top of the adjustment part is connected to a support plate, on which a fixing structure is connected.

[0007] Furthermore, the top of the adjustment part and the top of the support plate have a certain distance, and the distance is greater than half the height of the adjustment plate.

[0008] Furthermore, the fixing structure includes an adjusting plate, with support beams symmetrically connected to its four ends. The top of the support beams is connected to the bottom of the top support plate. The top of the top support plate is provided with a positioning groove, and the positioning groove is provided with multiple slots at equal intervals along its length.

[0009] Furthermore, four positioning slots are provided, which are respectively located at the top of the four ends of the top support plate.

[0010] Furthermore, the adjusting plate is provided with injection holes B for irrigating cement, and multiple injection holes B are provided, which are circumferentially arranged at equal intervals on the adjusting plate.

[0011] Furthermore, a placement groove is provided at the top of the adjustment part, and a placement rod is welded to the bottom of the adjustment plate.

[0012] Furthermore, the number of placement rods is the same as the number of adjustment parts, and the placement rods are inserted into the placement slots.

[0013] Furthermore, the connection method between the positioning component and the concrete structure is either pre-embedded irrigation or drilled threaded connection.

[0014] The beneficial effects of this invention are:

[0015] 1. The adjusting plate is finely adjusted by adjusting the horizontal and vertical control bolts. The support on the adjusting plate is fixed by grouting cement, which is more stable than the traditional hole adjustment.

[0016] 2. By setting a positioning groove on the top support plate and setting multiple slots at equal intervals on the positioning groove, the bottom fixing rods of different models of steel structure supports are clamped and fixed, thereby reducing the need for on-site drilling operations by workers.

[0022] Example 1

[0023] This application discloses an adjustable positioning device for a steel structure support node. Unlike common adjustment devices that use enlarged positioning holes to ensure fine adjustment, this application uses the adjustment part 2 to drive the adjustment plate 3 of the connected support to move, so that the support can be fixed in a designated position for easy cement pouring.

[0024] The device is supported as a whole by pre-casting a concrete structure 1 and connecting a certain number of positioning components 11 to the concrete structure 1. The positioning components 11 can be pre-embedded parts cast in the concrete structure 1 or anchor bolts that are drilled and threaded after the concrete structure 1 has set. The number of positioning components 11 is four or more, which can be changed according to the support to be installed. There is at least one positioning component 11 on each end face of the concrete structure 1. Each positioning component 11 is connected to an adjustment structure. The adjustment structure includes a positioning sleeve 26 that fits onto the positioning component 11. The positioning sleeve 26 is inserted into the positioning component 11, and a through hole is provided in the center of the positioning sleeve 26. The size of the through hole is the same as or larger than the diameter of the positioning component 11 by 1 to 2 cm. A transverse control bolt 27 is rotatably connected to the positioning sleeve 26. A slider 25 is threadedly connected to the transverse control bolt 27. The slider 25 is slidably connected to the adjustment part 2 through the slide groove 24. The two ends of the slider 25 are provided with locking blocks that slide in the slide groove 24. The two sides of the locking blocks are in contact with the inner wall of the slide groove 24. The slider 25 is slidably connected to the two ends of the slide groove 24 through the locking blocks and the slider 25 is prevented from falling off the slide groove 24. The bottom end of the positioning sleeve 26 is provided with a bottom tray 28. The bottom tray 28 is rectangular and its length is two-thirds of the distance between the inner walls of the adjusting part 2. This effectively reduces the weight of the bottom tray 28 and ensures that the bottom tray 28 can support the bottom end of the positioning sleeve 26 when it is moved to any position. The bottom end of the bottom tray 28 is rotatably connected to a vertical control bolt 29, which is threaded to the bottom of the adjusting part 2. When fine-tuning of the device is required, the positioning sleeve 26 is moved left and right by rotating the horizontal control bolt 27 to meet the horizontal movement requirements of the adjusting part 2. Rotating the vertical control bolt 29 controls the bottom tray 28 to move up and down. When the bottom tray 28 rises, it pushes the adjusting part 2 down. When the bottom tray 28 falls, the adjusting part 2 falls due to gravity. The position of the support placed on the fixed structure is changed by connecting the fixed structure to multiple adjusting parts 2. After adjustment, the horizontal control bolt 27 and the vertical control bolt 29 are cleaned by irrigation or cutting.

[0025] Furthermore, to prevent the adjusting part 2 from rotating around the positioning component 11 as an axis during adjustment, the contact end between the positioning component 11 and the positioning sleeve 26 can be rectangular, or the symmetrical ends of the positioning component 11 can be cut off while maintaining its circular shape, so that the outer contour of the positioning component 11 is arc-shaped on both sides and rectangular on the other two sides. After the end shape of the positioning component 11 is fixed, the shape of the through hole in the positioning sleeve 26 is changed to be the same as the shape of the positioning component 11, ensuring that the positioning sleeve 26 will not rotate and reducing the workload of the construction personnel during installation.

[0026] Example 2

[0027] Based on Example 1, such as Figure 3 As shown, a support plate 21 is installed at the top of the adjusting part 2, with the top of the support plate 21 contacting the bottom of the adjusting plate 3 to support the bottom of the adjusting plate 3. After the construction personnel have adjusted all the adjusting parts 2 according to the requirements, grouting holes A23 are symmetrically set on the left and right sides of the top of the adjusting part 2 to facilitate the construction personnel to pour cement into the adjusting part 2. Wooden boards or the like are used to surround the outside of the adjusting part 2 so that when the construction personnel pour cement, the cement can wrap the adjusting part 2 and the connected positioning component 11 and air dry and fix it. This makes the device as a whole, supports the adjusting plate 3, ensures the strength of the device itself, and ensures the safety of the device.

[0028] Example 3

[0029] Based on Example 2, such as Figure 5As shown, the fixing structure includes an adjusting plate 3. The adjusting plate 3 has multiple grouting holes B32 spaced evenly around its circumference for cement injection. This ensures that when construction workers pour cement from the top of the device, the cement flows in through the grouting holes B32, connecting the adjusting plate 3 to the concrete structure 1 without any dead angles, thus solidifying the entire device into a single unit and ensuring its strength. Support beams 33 are welded to all four ends of the adjusting plate 3. These support beams 33 support the steel structure support placed on top of the device, ensuring the steel structure support can be stably placed on the device. The top of the support beam 33 is welded to one end of the top support plate 34. There is a certain distance between the top of the support beam 33 and the top of the top support plate 34, which is greater than or equal to one-third and less than or equal to half the thickness of the support, protecting the top sidewall of the support. The distance between two support beams 33 varies depending on the size of the steel structure support to be placed, ensuring that the inner wall of each support beam 33 fits snugly against one end of the steel structure support, further improving the stability of the steel structure support. The top of the top support plate 34 is provided with a positioning groove 35. The positioning groove 35 is used to insert and place the fixing rod or supporting steel bar at the bottom of the support to fix the steel structure support and prevent the support from shifting during the cement pouring process. Multiple slots 36 are evenly spaced along the length of the positioning groove 35. The slots 36 are rectangular and their height is less than the height of the positioning groove 35. Construction workers insert the fixing rod at one end of the support into the positioning groove 35 and position it by inserting iron plates. The iron plates are the same shape and size as the slots 36. By inserting iron plates into the slots 36 at both ends of the fixing rod, the two iron plates are made to fit against the two ends of the fixing rod, preventing the fixing rod from moving within the positioning groove 35. To prevent the fixing rod from rotating or shifting within the positioning groove 35, the width of the inner wall of the positioning groove 35 is the same as the diameter of the fixing rod. After the iron plates are inserted, to ensure the connection is secure, construction workers need to weld the fixing rod or supporting steel bar to the contacting iron plate to prevent displacement during cement pouring. By setting positioning grooves 35 to limit the positioning of the supporting steel bar or the fixing rod at the bottom of the steel structure support, compared to the traditional method of drilling concrete holes for positioning based on the different models of the steel structure support after pouring concrete, the amount of work on-site is reduced, and work efficiency is improved.

[0030] Furthermore, in order to improve the stability of the device's support for the steel structure support, positioning grooves 35 are provided at the top of each of the four ends of the top support plate 34. The top support plate 34 can support the four ends of the steel structure support, thereby ensuring the stability of the device's connection to the steel structure support.

[0031] Example 4

[0032] Based on Example 3, such as Figure 3 and Figure 5 As shown, a placement rod 31 is welded to the bottom end of the adjusting plate 3. The placement rod 31 is snapped onto the top end of the adjusting part 2 through a placement groove 22. The placement groove 22 is located in the middle of the top end of the adjusting part 2. The outer contour of the placement groove 22 is rectangular. One end of the placement groove 22 is connected to one end of the top of the adjusting part 2, and the other end of the placement groove 22 is a certain distance from the other end of the top of the adjusting part 2. The distance is less than one-quarter of the length of the placement rod 31. The width of the placement groove 22 is the same as or greater than the width of the placement rod 31 by 1-2 cm. The front end of the placement rod 31 is attached to the inner wall of the front end of the placement groove 22. The placement groove 22 wraps and supports the placement rod 31, further improving the connection between the adjusting plate 3 and the adjusting part 2. The number of placement rods 31 is the same as the number of adjusting parts 2, and the positions of the multiple placement grooves 31 correspond one-to-one with the positions of the multiple placement grooves 22. This method reduces on-site welding operations and the device is constructed through assembly.
