Technical Field
[0001] This invention belongs to the field of pipeline installation technology in steel structure factory buildings, specifically relating to a load-bearing and seismic-resistant structure for heavy pipelines in large-span steel structure factory buildings. Background Technology
[0002] During the construction and use of large-span steel structure workshops, a large number of pipelines need to be installed, including heavy pipelines (such as large water pipelines and gas pipelines) and light pipelines (such as cable conduits and small infusion pipes). Currently, pipeline installation usually uses a hanger structure to connect and fix the pipelines to the steel beams of the steel structure workshop. However, the hanger structure has many shortcomings: on the one hand, the clamp structure is mostly a traditional tiger clamp, which has insufficient clamping force, is prone to deformation and loosening, and cannot be adapted to H-beams of different thicknesses, resulting in poor installation flexibility; on the other hand, the connection between the tie rod structure and the clamp structure is complex, and the clamps need to be completely disassembled when replacing the tie rod, which is cumbersome. In addition, the pipeline fixing structure has a single function and cannot be flexibly combined for hoisting according to the specifications and quantity of pipelines, and its load-bearing and seismic performance is difficult to meet the usage requirements of large-span steel structure workshops. Summary of the Invention
[0003] The purpose of this invention is to provide a load-bearing and seismic-resistant structure for heavy pipelines in large-span steel structure factory buildings, which solves the defects of poor adaptability of the hanger structure, unstable clamping, cumbersome disassembly and assembly, and insufficient flexibility in pipeline fixing in the existing technology, and realizes the adaptability to H-beams of different thicknesses, flexible combination and hoisting of pipelines, and stable load-bearing and seismic-resistant effect.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A load-bearing and seismic-resistant structure for heavy pipelines in large-span steel structure factory buildings includes a hanger structure, a heavy pipeline fixing structure, a light pipeline fixing structure, and an H-beam. The hanger structure comprises a clamping structure, a connecting structure, a tie rod structure, and a positioning structure.

When one hanger structure is installed on the H-beam, it can suspend one light pipeline via the light pipeline fixing structure. When two or more hanger structures are installed on the H-beam, a single hanger structure can not only suspend a light pipeline via the light pipeline fixing structure, but also allow the installation of a heavy pipeline fixing structure between any two adjacent hanger structures via their positioning structures. A heavy pipeline or multiple light pipelines can be installed on the heavy pipeline fixing structure, and its length is determined by the spacing between the positioning structures of adjacent hanger structures.

Several concave grooves are opened opposite each other on the inner arc surfaces.
[0007] Preferably, the pull rod structure includes a pull rod, with a plurality of positioning rings equidistantly sleeved on the outer side of the top of the pull rod. A rubber ring is fixed to the bottom end of each positioning ring and is fitted onto the pull rod.

The bottom end of the rubber ring contacts the bottom surface of the concave groove. The top of the pull rod is positioned between two arc-shaped plates, the diameter of the inner arc surface of the arc-shaped plates matching the diameter of the pull rod. A plurality of positioning holes are evenly spaced on the outer wall of the pull rod.
[0008] Preferably, the positioning structure includes a first positioning cylinder that slides onto the pull rod. A plurality of first positioning pins are equidistantly arranged through the first positioning cylinder. The first positioning pins are slidably disposed with the first positioning cylinder, pass through positioning holes, and are slidably connected to it. One end of each of the plurality of first positioning pins is fixed to the same first connecting plate, and the other end is provided with an external thread and screwed with a locking nut. A handle is fixed to the side wall of the first connecting plate.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) Strong adaptability: By setting the first threaded rod in the clamping structure, the distance between the upper clamping plate and the lower clamping plate can be adjusted to adapt to H-steel beams with different lower flange thicknesses, thus expanding the applicable range of the structure; (2) Good clamping stability: The clamping structure adopts the cooperation of top plate, second threaded rod and guide rod. When tightening the second threaded rod, the lever principle is used to make the upper clamping plate tightly clamp the lower flange of H steel beam. Compared with traditional tiger clamp, it prevents deformation and loosening, and improves clamping force and seismic stability. (3) Easy to disassemble and assemble: The connection structure enables the detachable connection between the pull rod structure and the clamp structure. When replacing the pull rod structure, there is no need to disassemble the clamp structure, only the connection structure needs to be disassembled, which simplifies the operation process and improves maintenance efficiency; (4) Flexible hoisting: The positioning structure can be adjusted at any position on the tie rod structure, which is convenient for adjusting the installation position of the heavy pipeline fixing structure. By increasing the number of positioning structures, multiple heavy pipeline fixing structures can be hoisted on the same hanger structure in conjunction with adjacent hanger structures. Heavy pipelines are fixed on the heavy pipeline fixing structure by U-shaped clamps. At the same time, light pipelines can also be hoisted at the bottom of the hanger structure by the pipeline clamps of the light pipeline fixing structure, so as to realize the flexible combination hoisting of pipelines.

[0016] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example 1
[0017] like Figure 1 , 2As shown in Figures 4 and 8, a load-bearing and seismic-resistant structure for heavy pipelines in a large-span steel structure factory building includes a hanger structure 1, a heavy pipeline fixing structure 2, a light pipeline fixing structure 3, and an H-beam 4. The hanger structure 1 includes a clamping structure 5, a connecting structure 6, a tie rod structure 7, and a positioning structure 8. The clamping structure 5 is fixed to the lower flange of the H-beam 4. The connecting structure 6 is detachably fixed to the bottom end of the clamping structure 5 by bolts. The top end of the tie rod structure 7 is clamped into the connecting structure 6. The positioning structure 8 is slidably sleeved on the tie rod structure 7. The light pipeline fixing structure 3 is inserted into the bottom end of the tie rod structure 7. A hanger structure 1 is installed on the H-beam 4, and a light pipeline is suspended by the light pipeline fixing structure 3. The clamping structure 5 includes two semi-conical blocks 11. Each semi-conical block 11 has a first connecting lug 12 fixed to both sides. The two semi-conical blocks 11 are bolted together via the first connecting lugs 12 to form a complete cone shape. A first semi-circular flange 10 is fixed to the top of each semi-conical block 11. A lower clamping plate 9 is bolted to the top of each first semi-circular flange 10. First reinforcing ribs 18 are symmetrically fixed to both sides of the bottom of the lower clamping plate 9. An adjusting plate 47 is provided between the two first reinforcing ribs 18.

An installation groove 50 is opened on the top surface of the upper clamping plate 19. The cylinder 49 is set in the installation groove 50. A fixed shaft 51 is sleeved inside the cylinder 49. The two ends of the fixed shaft 51 are fixedly connected to the inner walls of both sides of the installation groove 50. A top plate 22 is provided between the upper clamping plate 19 and the lower clamping plate 9. A second threaded rod 23 is rotatably connected to the bottom end of the top plate 22 through a bearing.

The bottom ends of the two semi-circular conical blocks 11 are fixed with the second semi-circular flange 13. The initial distance between the upper clamping plate and the lower clamping plate is adjusted by the first threaded rod, adjusting plate, sliding plate and cylinder to adapt to H-beams with different lower flange thicknesses, so that the upper clamping plate and the lower clamping plate are engaged on both sides of the lower flange of the H-beam to achieve the fixation of the clamping structure. Through the top plate, the second threaded rod and the guide rod, the lever principle of the second threaded rod is used to make the upper clamping plate clamp the lower flange of the H-beam to avoid deformation and loosening.
[0018] like Figure 4As shown, the connecting structure 6 includes two third semicircular flanges 15, which are detachably fixed to the bottom ends of two second semicircular flanges 13 by bolts.

Several concave grooves 17 are formed on the inner arc surfaces of the two arc plates 14 in pairs. The threaded connection between the first threaded rod 21 and the adjusting plate 47 is a fine thread, as is the threaded connection between the second threaded rod 23 and the lower clamping plate 9. The clearance between the positioning ring 26 and the concave groove 17 is ≤0.5mm. The tie rod structure is connected via the second semicircular flange, the third semicircular flange, the arc plate, and the second connecting ears, achieving a detachable connection between the tie rod structure and the clamping structure. This connection is simple to assemble and disassemble, and easy to maintain.
[0019] like Figure 5 , 8 As shown, the tie rod structure 7 includes a tie rod 25. Several positioning rings 26 are equidistantly sleeved on the outer side of the top of the tie rod 25.

The size of the positioning rings 26 is adapted to the size of two corresponding concave grooves 17. The positioning rings 26 are engaged in the two corresponding concave grooves 17. The bottom of the rubber rings 27 contacts the bottom surface of the concave grooves 17. The top of the tie rod 25 is set between two arc plates 14. The diameter of the inner arc surface of the arc plate 14 is adapted to the diameter of the tie rod 25. Multiple positioning holes 28 are evenly opened on the outer wall of the tie rod 25. When the rubber rings are compressed, shock absorption is achieved, improving the load-bearing and shock resistance.
[0020] like Figure 5-6 As shown, the positioning structure 8 includes a first positioning cylinder 29 slidably sleeved on the pull rod 25. Several first positioning pins 31 are equidistantly arranged through the first positioning cylinder 29.

The axis of the limiting cylinder 33 is parallel to the axis of the first positioning cylinder 29. The positioning structure can be arbitrarily adjusted on the pull rod structure by the first positioning pins of the positioning structure combined with the positioning holes of the pull rod structure, which facilitates the adjustment of the installation position of the heavy pipeline fixing structure and realizes flexible hoisting.
[0021] like Figure 5 , Figure 7As shown, the lightweight pipeline fixing structure 3 includes a second positioning cylinder 34 slidably sleeved on the bottom end of the pull rod 25. Several second positioning pins 37 are equidistantly arranged on the second positioning cylinder 34. The second positioning pins 37 are slidably connected to the second positioning cylinder 34 and pass through the positioning hole 28 and slide with it. One end of the several second positioning pins 37 is fixed to the same second connecting plate 35. The other end of the second positioning pin 37 is provided with external thread and screwed with a locking nut. A pull ring 36 is fixed on the side wall of the second connecting plate 35. A threaded rod 38 for connecting the pipeline clamp 40 is fixed to the bottom end of the second positioning cylinder 34.

The second positioning pins pass through the positioning hole through the pull ring and the second connecting plate, and are fixed by the locking nut at the other end of the second positioning pin. The lightweight pipeline is clamped by the pipeline clamp, the threaded rod and the first fixing nut.
[0022] The specific steps for hoisting lightweight pipelines based on the above structure are as follows: S1: Install clamping structure 5: According to the thickness of H steel beam 4, rotate the hexagonal nut at the bottom of the first threaded rod 21, and drive the sliding plate 48 and cylinder 49 to move through the adjusting plate 47, adjust the initial distance between the upper clamping plate 19 and the lower clamping plate 9, and clamp the upper clamping plate 19 and the lower clamping plate 9 on both sides of the lower flange of H steel beam 4. Then rotate the hexagonal nut at the bottom of the second threaded rod 23 to push the top plate 22 to move upward, so that the upper clamping plate 19 tightly clamps the H steel beam 4, and complete the fixing of clamping structure 5. S2: Install connection structure 6: Fix the two third semicircular flanges 15 to the bottom ends of the two second semicircular flanges 13 respectively with bolts, and then connect and fix the two arc plates 14 with bolts through the second connecting ears 16; S3: Install the tie rod structure 7: Align the positioning ring 26 at the top of the tie rod 25 with the concave groove 17 on the inner arc surface of the arc plate 14, place the top of the tie rod 25 between the two arc plates 14, embed the positioning ring 26 into the concave groove 17, and make the rubber ring 27 contact the bottom surface of the concave groove 17 to complete the snap-fit of the tie rod structure 7. S4: Install the lightweight pipeline fixing structure 3: Place the second positioning cylinder 34 on the bottom of the pull rod 25, adjust it to a suitable position, and then use the pull ring 36 to drive the second connecting plate 35 so that the second positioning pin 37 passes through the positioning hole 28. Thread a locking nut to the other end of the second positioning pin 37 to fix it. Place the pipeline clamp 40 on the lightweight pipeline, and pass the threaded rod 38 through the pipeline clamp 40. Thread the first fixing nut 39 to clamp it, thus completing the hoisting of the lightweight pipeline. Example 2
[0023] A further implementation of the above embodiment 1 is as follows: Figure 1As shown, when two or more hanger structures 1 are installed on H-steel beam 4, a single hanger structure 1 can suspend a light pipeline through a light pipeline fixing structure 3. A heavy pipeline fixing structure 2 is installed between any two adjacent hanger structures 1 through their positioning structures 8. A heavy pipeline or multiple light pipelines can be installed on the heavy pipeline fixing structure 2. The length of the heavy pipeline fixing structure 2 is adapted according to the spacing of the positioning structures 8 between the two adjacent hanger structures 1.
[0024] like Figure 3 As shown, the heavy pipeline fixing structure 2 includes a crossbeam 41. A third reinforcing rib 42 is horizontally fixed at the center of the bottom surface of the crossbeam 41. Insert rods 44 are symmetrically fixed on both sides of the bottom surface of the crossbeam 41. When assembling the heavy pipeline fixing structure 2, the two insert rods 44 are respectively inserted into the limiting cylinders 33 of the two adjacent lifting rod structures 1. The bottom end of the insert rod 44 is provided with an external thread and screwed with a second fixing nut 45. The pipeline is fixed on the top surface of the crossbeam 41 by a U-shaped clamp 43. Several mounting holes 46 are opened on the top surface of the crossbeam 41 for U-shaped clamps 43 of different sizes to pass through and be fixed. The heavy pipeline fixing structure is fixed by insert rods, limiting cylinders, and the second fixing nut at the bottom end of the insert rods. The heavy pipeline is fixed by U-shaped clamps on the heavy pipeline, or multiple light pipelines are fixed at the mounting holes of the crossbeam by U-shaped clamps as needed. The heavy pipeline is fixed by screwing the nuts, realizing the flexible combination and hoisting of heavy and light pipelines.
[0025] The specific steps for hoisting heavy pipelines or multiple light pipelines based on the above structure are as follows: S1: Following steps S1-S3 in Example 1, install two or more adjacent hanger structures 1 on the H-steel beam 4; S2: Install positioning structure 8: Place the two first positioning cylinders 29 onto the pull rods 25 of the two hanging rod structures 1 respectively, and adjust them to the same height. Then, drive the first connecting plate 30 through the handle 32 to make the first positioning pin 31 pass through the positioning hole 28. Thread a locking nut onto the other end of the first positioning pin 31 to fix it. S3: Install heavy pipeline fixing structure 2: According to the spacing of the limiting cylinders 33 in the positioning structure 8 on the adjacent lifting rod structure 1, make a crossbeam plate 41 of the corresponding length. Insert the insertion rods 44 on the bottom surface of the crossbeam plate 41 into the corresponding limiting cylinders 33 respectively. Screw the second fixing nut 45 at the bottom end of the insertion rod 44 to fix it. Pass the U-shaped clamp 43 through the mounting hole 46 on the crossbeam plate 41 and put it on the heavy pipeline. Or, as needed, fix multiple light pipelines to the mounting hole 46 of the crossbeam plate 41 respectively through the U-shaped clamp 43 and screw the nuts to fix them. This completes the hoisting of the heavy pipeline or multiple light pipelines.
