Abstract
Description
Technical Field

[0002] In the field of steel structure engineering, the installation of suspended pipes, equipment, or ceilings in large-span buildings such as industrial plants and airport terminals typically relies on the following methods:
[0003] 1. Adding secondary beams: Adding secondary beams to the main beams or columns of the steel structure to provide suspension supports. While this method ensures that the load is transferred to the main structure, it significantly increases construction costs, structural weight, and construction complexity.

[0005] 1) It damages the galvanized layer of the purlins, accelerating corrosion;
[0006] 2) Heat deformation may affect the stability of purlins, especially thin-walled C-type or H-type purlins;
[0007] 3) The welding skills required for construction workers are high, and the quality is difficult to guarantee.
[0008] 3. Embedded lifting points: These require high positioning accuracy and cannot be adjusted later. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a novel steel structure additional purlin hanging point structure, comprising: a load-bearing steel 1 and roof purlins 5. Two load-bearing steel 1s are provided, each U-shaped, with their back sides parallel. A movable cavity 3 is provided between the two load-bearing steel 1s. Additional roof purlins 4 are connected to the left and right ends of both load-bearing steel 1s via fixing plates 6. The outer ends of the additional roof purlins 4 are fixedly connected to the roof purlins 5 via fixing bolts, thus fixing the load-bearing steel 1 between the two roof purlins 5. The additional roof purlins 4 are C-shaped and fitted onto the left and right ends of the load-bearing steel 1. The fixing plate 6 is Z-shaped and overlaps the outer end of the newly added roof purlin 4. The fixing plate 6 is L-shaped, with one end fixed to the load-bearing steel 1 by fixing bolts, and the other end fixed to the newly added roof purlin 4 and roof purlin 5 by fixing bolts. Bolt holes for corresponding fixing bolts are opened on both ends of the fixing plate 6 and on the side walls of the load-bearing steel 1, the newly added roof purlin 4 and the roof purlin 5. The roof purlin 5 overlaps the outer end of the newly added roof purlin 4. The bolt holes on the roof purlin 5 and the newly added roof purlin 4 are connected. The fixing bolts pass through several bolt holes in sequence and the nuts are tightened to fix the load-bearing steel 1 between the roof purlins 5.
[0027] Each load-bearing steel bar 1 has a rack 2 fixedly installed at its upper end. The two racks 2 are arranged in parallel. A moving plate 9 is slidably connected inside the moving cavity 3. The upper end of the moving plate 9 extends out of the moving cavity 3 and is fixedly installed with a slider 7. The slider 7 is U-shaped. The upper end of the moving plate 9 is fixed at the center of the inner end of the slider 7. Several toothed blocks 8 are fixedly installed on both the front and rear sides of the inner end of the slider 7. The toothed blocks 8 are located on the front and rear sides of the moving plate 9, respectively. The slider 7 is engaged with the racks 2 through the toothed blocks 8. The toothed blocks 8 and the racks 2 interlock with each other. At the same time, the side walls of the front and rear ends of the slider 7 and the front and rear ends of the two racks 2 are also engaged. The sidewall sliding connection limits the connection between the toothed block 8 and the rack 2, preventing misalignment when they mesh, thus fixing the slider 7 and the moving plate 9. When the position of the slider 7 and the moving plate 9 needs to be changed, the slider 7 is moved upward, and the slider 7 moves synchronously with the toothed block 8 and separates from the rack 2. The slider 7 and the moving plate 9 can then be moved. When the moving plate 9 moves, the lower end of the hanging column 10 and the hanging ring 14 move synchronously. After moving to the appropriate position, the slider 7 is lowered, allowing the toothed block 8 and the rack 12 to mesh again and fix them in place, making it easy to adjust the position.
[0028] A hanging column 10 is fixedly installed at the lower end of the movable plate 9. A reinforcing block 11 is fixedly installed at the connection between the hanging column 10 and the movable plate 9. One end of the reinforcing block 11 is fixed to the outer side of the upper end of the hanging column 10, and the other end is fixed to the outer wall of the movable plate 9 to reinforce the connection between the hanging column 10 and the movable plate 9. A lifting ring 14 is fixedly installed at the lower end of the hanging column 10, and the lifting ring 14 can be used as a lifting point.
[0029] The upper end of the hanging column 10 is provided with a threaded groove 12, and an adjusting nut 13 is threadedly connected to the threaded groove 12. By turning the adjusting nut 13, it is brought into contact with the lower end of the load-bearing steel 1, thus fixing the hanging column 10. When it is necessary to change the position of the hanging column 10, the adjusting nut 13 is turned downward to separate the adjusting nut 13 from the load-bearing steel 1, thereby moving the slider 7 upward, separating the tooth block 8 from the rack 12, and allowing the slider 7 to move along with the moving plate 9 and the hanging column 10.
[0030] When this device is in operation, additional roof purlins 4 are installed on the inside of the roof purlins 5 using fixing bolts. Two parallel load-bearing steel bars 1 are fixedly installed between the two additional roof purlins 4 using fixing bolts. A movable plate 9 is slidably connected between the two load-bearing steel bars 1, and a hanging column 10 is fixedly installed at the lower end of the movable plate 9. Through the parallel and coordinated force-bearing of the two additional purlins, the suspended load is distributed to the two adjacent additional roof purlins 4, solving the problem of insufficient load-bearing capacity of a single purlin. At the same time, the fixing plate 6 enhances the overall stability and avoids local buckling. Using the additional roof purlins 4 as the main load-bearing components, the suspended load is transferred to the roof purlins through the load-bearing steel bars 1, forming a three-level force transmission path of "additional purlins - connectors - roof purlins".

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
