Description

Technical Field

[0001] This application relates to a mounting bracket for a pin-connection node structure, belonging to the technical field of steel structure pin base assembly. Background Technology

[0002] In steel structure engineering, cast steel pin-connected joint bases are commonly used for steel structure support in large stadiums, long-span heavy bridges, etc. They achieve load transfer and accommodate structural deformation through a hinged connection. The cast steel pin-connected joint base consists of a lower cast steel component and an upper cast steel component. A bearing is rotatably connected to the lower cast steel component, and a pin is mounted on the upper cast steel component. The pin passes through the bearing, and the upper cast steel component rotates on the lower cast steel component.

[0003] Because the pin connection node is a large-sized heavy steel structure and the pin hole fit dimensions are highly precise, the ordinary assembly method is labor-intensive, time-consuming, and dangerous, and does not meet the needs of large-scale installation.

[0004] To reduce the construction difficulty, construction cost, and operational risks of installing large cast steel pins, this pin base auxiliary mounting bracket was designed and manufactured. It can greatly improve work efficiency, reduce labor intensity, and effectively reduce the occurrence of personal injury accidents.

[0005] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a mounting bracket with a pin-connected node structure to overcome the defects in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide an installation frame for a pin connection node structure that can reduce the construction difficulty, construction cost, and operational risks of installing large cast steel pins, greatly improve work efficiency, reduce labor intensity, and effectively reduce personal injury accidents.

[0032] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 18 As shown, this utility model is a mounting bracket with a pin-shaft connection node structure, including a mounting bracket assembled from several H-beams. The mounting bracket includes a base 11, and two rotating rods 3 are rotatably connected to the base 11 at one end. The bottom end of the lower cast steel part 1 is mounted on the rotating rods 3 via a bolt and nut structure 5. The rotating rods 3 can drive the lower cast steel part 1 to rotate 90°. A through groove 9 is provided on the end of the rotating rod 3 away from the rotating axis. A support rod 31 is detachably connected to the base 11. After the rotating rod 3 rotates 90°, it cooperates with the support rod 31 through the through groove 9, forming a fixed structure between the support rod 31, the rotating rod 3, and the base 11.

[0033] A support is installed on the base 11. The support is a U-shaped steel frame 7. The top of the U-shaped steel frame 7 is a flat plate. After the lower cast steel part 1 is rotated 90°, one end is placed on the flat plate on the U-shaped steel frame 7. A fine-adjustment rubber shim 8 is placed on the flat plate. The fine-adjustment rubber shim 8 ensures that the lower cast steel part 1 is in a horizontal position, so as to facilitate the subsequent installation of the lower cast steel part 1 and the bearing 19.

[0034] In this embodiment, the bearing 19 is a spherical bearing. Fixed discs 20 are mounted on both sides of the bearing 19. Two screws pass between the two discs 20. The screws are detachably connected to the discs 20 by a bolt and nut structure. A long rod 21 passes through the center of the bearing 19. The long rod 21 is installed on the base 11 by a bolt and nut structure 51. A jack 25 can be installed on the top of the bearing 19. The output end of the jack 25 faces downward towards the cast steel part 1. In this embodiment, the jack 25 is a hollow hydraulic jack.

[0035] The mounting bracket also includes an adjustment component, which includes two U-shaped support plates 27. The U-shaped support plates 27 are installed on both sides of the bottom of the lower cast steel part 1. The distance between the U-shaped support plates 27 and the lower cast steel part 1 is adjusted by a bolt and nut structure. The upper cast steel part 26 can be placed on the top of the U-shaped support plates 27. The U-shaped support plates 27 are used to adjust the position of the upper cast steel part 26 to ensure that the upper cast steel part 26 and the lower cast steel part 1 are coaxial.

[0036] The mounting bracket is also equipped with an adjustment component two, which includes a U-shaped support plate two 30. The distance between the U-shaped support plate two 30 and the base 11 is adjusted by a bolt and nut structure. The U-shaped support plate two 30 is used to change the position of the adjustment dummy shaft 28 and the pin shaft 4 to ensure that the upper cast steel part 26, the lower cast steel part 1, the dummy shaft 28 and the pin shaft 4 are coaxial.

[0037] A hollow hydraulic jack 29 is provided on the side of the adjusting part away from the lower cast steel part 1. The hollow hydraulic jack 29 is used to push the dummy shaft 28 and the pin shaft 4 into the upper cast steel part 26 and the lower cast steel part 1.

[0038] The working principle of the mounting bracket for the pin-connection node structure of this utility model is as follows:

[0039] First, fix the lower cast steel part 1 to the rotating rod 3 with high-strength bolts 5. Using a hand chain hoist or indoor crane, slowly rotate the lower cast steel part 1 90° around the hinge of the rotating rod 3 until the edge of the lower cast steel part 1 rests on the U-shaped steel frame 7. Fine-tune the number of layers of rubber shims 8 to ensure that the lower cast steel part 1 is in the right position. Fix the support rod 31 between the rotating rod 3 and the base 11 to fix the lower cast steel part 1. Inspect the assembly area of ​​the upper cast steel part 26 and the bearing 19, apply grease, remove the bearing 19 from the freezer and wipe its surface dry. Install discs 20 on both sides of the bearing 19 and tighten them with two M12 screws. Insert the long rod 21 through the center of the two discs 20 and fix it with a bolt and nut structure. Pass the long rod 21 through the lower cast steel column and insert it vertically into the base 11. Fix the long rod 21 to the base 11 with the bolt and nut structure 51. Install jack 25 on the top of the long rod 21 and slowly push the discs 20 in until the bearing 19 is completely installed in the lower cast steel part 1. Remove jack 25, discs 20 and long rod 21. Install the sealing hoist and the coupling ring for fixing the bearing 19 on the lower cast steel part 1. Remove the support rod 31 and use a hand chain hoist in conjunction with an indoor crane to slowly flip the lower cast steel part 1 back onto the base 11. Install U-shaped support plates 27 on both sides of the bottom of the lower cast steel part 1. Place the upper cast steel part 26 on top of the two U-shaped support plates 27. Adjust the position of the U-shaped support plates 27 using bolt and nut structure to ensure the concentricity of the upper cast steel part 26 and the lower cast steel part 1. Install U-shaped support plates 30 and jacks 29 on the mounting frame. Place the dummy shaft 28 on the U-shaped support plates 30. Adjust the position of the U-shaped support plates 30 using bolt and nut structure to ensure the concentricity of the dummy shaft 28, the lower cast steel part 1, and the upper cast steel part 26. Start jacks 29 to insert the dummy shaft 28 into the bearing 19. Take out the pin 4 and place it on the U-shaped support plates 30. Slowly push it in with the jack to replace the dummy shaft 28. After the dummy shaft 28 is completely replaced, install thrust washers and cover plates on the upper cast steel part 26. Fix the countersunk bolts and check that they are tightened. The installation of the pin connection node structure is completed.
