Description

Technical Field

[0001] This invention relates to the field of trestle panel structure technology, and in particular to a modular splicing construction trestle panel structure. Background Technology

[0002] In the construction industry, construction trestle bridges, as temporary access facilities, directly impact construction efficiency due to the ease of installation, dismantling, and maintenance of their panel structures. Currently, conventional modular construction trestle bridge panels typically employ a bolt-through locking installation method, requiring individual hole drilling, bolt insertion, and tightening—a cumbersome process that leads to low installation and dismantling efficiency and consumes significant manpower and time. Furthermore, the existing panel splicing structure design is flawed; after splicing, each module forms a rigid whole without dedicated replacement structures. When a single panel is worn or damaged and needs replacement, it is difficult to separate it individually. In addition, the panel splicing gaps are small, and individual panels are tightly fitted to adjacent modules, lacking load-bearing supports. Dismantling requires removing multiple surrounding panels, further increasing maintenance workload, extending construction time, and reducing panel turnover rate, failing to meet the needs of efficient and convenient use on construction sites. Summary of the Invention

[0003] The main objective of this invention is to provide a modular splicing construction trestle panel structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A modular, splicing construction trestle panel structure includes several sets of distribution beams. Six sets of bridge panels are laid on the upper ends of these distribution beams. Each of the six sets of bridge panels is equipped with two sets of hoisting assemblies. Positioning components are installed in each of the distribution beams corresponding to the positions of the hoisting components. Two sets of limiting plates are fixedly installed on both sides of the lower side of each of the six sets of bridge panels, corresponding to the sides of each positioning component. Positioning openings are provided on the inner sides of the limiting plates. Each hoisting assembly includes a retractable cylinder fixedly installed at the lower end of the bridge panel. An inner cylinder is fixedly installed inside the retractable cylinder. The retractable cylinder and the inner... An annular slide is provided between the inner and outer cylinders. A movable ring is movably arranged inside the annular slide. A first spring is fixed between the movable ring and the bottom of the inner side of the shrink cylinder. Two sets of fixing plates are fixedly arranged at the upper end of the movable ring. A rotating shaft is movably arranged between the two sets of fixing plates near the upper side. A lifting ring is fixed between the two sets of rotating shafts. A counterweight is arranged on one side of the lifting ring. Two sets of spring plates are fixedly arranged at the upper end of the inner cylinder. A guide plate is arranged on the upper side of the two sets of spring plates. A notch is opened on the upper side of the inner cylinder corresponding to the positions of the two sets of fixing plates.

[0005] Preferably, a threaded cap is threadedly connected to the inner side of the bridge deck corresponding to the position of the shrink cylinder. A hexagonal groove is formed on the upper side of the threaded cap, and a groove cap is inserted into the hexagonal groove. A threaded opening is formed on the inner side of the bridge deck corresponding to the position of the threaded cap.

[0006] Preferably, the positioning assembly includes a fixed cylinder fixedly disposed on the inner side of the distribution beam at the position corresponding to the lower side of the threaded opening. Two sets of fixed shafts are fixedly disposed on both sides of the upper side of the distribution beam near the fixed cylinder. A steering roller is movably disposed between the two sets of fixed shafts. A positioning plate is slidably disposed on the inner side of the steering roller. A rotating shaft is fixedly disposed on one side of the positioning plate. A threaded groove is opened inside the lower side of the fixed cylinder. A threaded rod is threadedly connected to the inner side of the threaded groove. A movable rod is fixedly disposed at the upper end of the threaded rod. A movable part is sleeved on the outer side of the movable rod. Openings are opened on both sides of the upper side of the fixed cylinder corresponding to the movable part. A bolt head is fixedly disposed at the upper end of the movable rod. A second spring is sleeved on the outer side of the movable rod between the bolt head and the movable part. A locking slot is opened at both ends of the upper side of the distribution beam at the position corresponding to the limiting plate.

[0007] Preferably, the shrink tube and the inner tube are an integral structure, the inner tube corresponds to the lifting ring, and the first spring is in a compressed state.

[0008] Preferably, the fixing piece is inserted inside the notch, the two sets of spring pieces position the lifting ring on the upper side of the inner cylinder, and the guide piece is inclined.

[0009] Preferably, the threaded cap is disposed in the threaded opening, and the threaded cap corresponds to the position of the shrink cylinder.

[0010] Preferably, the positioning plates on both sides of the distribution beam are inserted into the positioning holes on both sides to restrict the movement of the limiting plate, and the positioning plates are arc-shaped on the side corresponding to the positioning holes.

[0011] Preferably, the movable part is slidably disposed inside the opening, the bolt head is adapted to the fixed cylinder, and the bayonet is adapted to the limiting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When the bridge deck needs to be installed on several fixed sets of distribution beams, the limiting plate fixed on the lower side of the bridge deck is inserted into the bayonet. Through the cooperation between the limiting plate and the bayonet, the bridge deck is restricted from moving in all directions. The limiting plate continues to move downward and contacts the limiting positioning plate, pushing the limiting positioning plate to rotate along the steering roller in the fixed cylinder. At the same time, the rotating shaft pushes the movable part to slide on the movable rod. The movable part is pushed upward and squeezes the second spring. While the limiting positioning plate rotates, it retracts inward to the steering roller until the limiting positioning plate is aligned with the positioning port. Then, the second spring pushes the movable part in the opposite direction, so that the limiting positioning plate is locked into the positioning port, forming a limiting constraint on the limiting plate. This avoids complicated disassembly and assembly procedures, low efficiency, inability to replace individual panels after splicing, difficulty in removal due to narrow gaps, poor turnover, and difficulty in adapting to the needs of efficient on-site construction.

[0013] During disassembly, open the threaded cover and use a tool to manipulate the bolt head to rotate the threaded rod, thereby driving the moving part to move downward. The moving part causes the positioning plates of the limit parts on both sides to tilt upward, releasing their locking restriction on the limit plates. This allows for quick disassembly of the entire structure as well as independent disassembly and replacement of a single bridge panel.

[0014] The slot cover is fastened to the outside of the hexagonal slot to shield and protect the hexagonal slot, effectively reducing the accumulation and blockage of dirt. At the same time, the threaded cover is used to shield and protect the threaded opening on the outside of the positioning component, effectively preventing mud and dirt from entering and causing blockage and corrosion, extending the service life of the component. Moreover, the protective structure is compact and integrated, and can be installed and covered immediately without additional modifications, making it suitable for harsh outdoor working conditions on construction sites.

[0015] After opening the threaded cover, pull the lifting ring upwards to disengage it from the spring clip. The first spring will automatically eject the movable ring and lifting ring from the threaded opening. Under the weight of the counterweight, the lifting ring will automatically maintain a vertical position after ejection, quickly establishing a lifting force point. This allows workers to use the vertical lifting ring to lift and remove a single bridge panel from the narrow panel splicing gap. When the lifting ring is locked inside the spring clip, it can maintain a horizontal position without occupying operating space, making it convenient for tools to reach inside and adjust the positioning components.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1-8This invention provides an embodiment of a modular splicing construction trestle panel structure, comprising several sets of distribution beams 1, with six sets of bridge panels 2 laid on the upper ends of the distribution beams 1. Each of the six sets of bridge panels 2 is equipped with two sets of hoisting components 3. Positioning components 4 are provided in each of the distribution beams 1 corresponding to the position of each set of hoisting components 3. Two sets of limiting plates 5 are fixedly installed on both sides of each set of positioning components 4 on the lower side of the six sets of bridge panels 2. Positioning openings 6 are provided on the inner side of the limiting plates 5. The hoisting components 3 include a retractable cylinder 31 fixedly installed at the lower end of the bridge panel 2, with an inner cylinder 32 fixedly installed inside the retractable cylinder 31. The retractable cylinder 31 and the inner cylinder 32 are connected... An annular slide 33 is provided, and a movable ring 34 is movably provided inside the annular slide 33. A first spring 35 is fixedly provided between the movable ring 34 and the bottom of the inner side of the shrink cylinder 31. Two sets of fixing plates 36 are fixedly provided at the upper end of the movable ring 34. A rotating shaft 37 is movably provided between the two sets of fixing plates 36 near the upper side. A lifting ring 38 is fixedly provided between the two sets of rotating shafts 37. A counterweight plate 39 is provided on one side of the lifting ring 38. Two sets of spring plates 310 are fixedly provided at the upper end of the inner cylinder 32. A guide plate 311 is provided on the upper side of the two sets of spring plates 310. A notch 312 is provided on the upper side of the inner cylinder 32 corresponding to the positions of the two sets of fixing plates 36.

[0021] The shrink tube 31 and the inner tube 32 are an integral structure. The inner tube 32 corresponds to the lifting ring 38. The first spring 35 is in a compressed state. The fixing plate 36 is inserted into the inner side of the notch 312. The two sets of spring plates 310 position the lifting ring 38 on the upper side of the inner tube 32. The guide plate 311 is inclined.

[0022] After opening the threaded cover 313, pull the lifting ring 38 upward to disengage it from the spring clip 310. The first spring 35 can automatically pop the movable ring 34 and the lifting ring 38 out of the threaded opening 316. Under the gravity of the counterweight 39, the lifting ring 38 automatically maintains a vertical position after popping out, quickly establishing a lifting force point. This makes it easy for workers to use the vertical lifting ring 38 to lift and remove the single bridge panel 2 as a whole from the narrow panel splicing gap. When the lifting ring 38 is locked inside the spring clip 310, it can maintain a horizontal position without occupying operating space, making it convenient for tools to be inserted inside to adjust and control the positioning component 4.

[0023] A threaded cap 313 is threadedly connected to the inner side of the bridge deck 2 at the position corresponding to the shrink cylinder 31. A hexagonal groove 314 is provided on the upper side of the threaded cap 313. A groove cap 315 is inserted into the hexagonal groove 314. A threaded opening 316 is provided on the inner side of the bridge deck 2 at the position corresponding to the threaded cap 313.

[0024] The threaded cap 313 is set in the threaded opening 316, and the threaded cap 313 corresponds to the position of the shrink cylinder 31.

[0025] The groove cover 315 is fastened to the outside of the hexagonal groove 314 to protect the hexagonal groove 314 and effectively reduce the accumulation and blockage of dirt. At the same time, the threaded cover 313 is used to cover and protect the threaded opening 316 on the outside of the positioning component 4, effectively preventing mud and dirt from entering and causing blockage and corrosion, extending the service life of the components. Moreover, the protective structure is compact and integrated, and can be installed and covered immediately without additional modification, making it suitable for harsh outdoor working conditions on construction sites.

[0026] The positioning assembly 4 includes a fixed cylinder 41 fixedly installed on the inner side of the distribution beam 1 at the position corresponding to the lower side of the threaded opening 316. Two sets of fixed shafts 42 are fixedly installed on both sides of the upper side of the distribution beam 1 near the fixed cylinder 41. A steering roller 43 is movably installed between the two sets of fixed shafts 42. A positioning plate 44 is slidably installed on the inner side of the steering roller 43. A rotating shaft 45 is fixedly installed on one side of the positioning plate 44. A threaded groove 46 is opened inside the lower side of the fixed cylinder 41. A threaded rod 47 is threadedly connected to the inner side of the threaded groove 46. A movable rod 48 is fixedly installed at the upper end of the threaded rod 47. A movable part 49 is sleeved on the outer side of the movable rod 48. An opening 410 is opened on both sides of the upper side of the fixed cylinder 41 corresponding to the movable part 49. A bolt head 411 is fixedly installed at the upper end of the movable rod 48. A second spring 412 is sleeved on the outer side of the movable rod 48 between the bolt head 411 and the movable part 49. A latch 413 is opened at both ends of the upper side of the distribution beam 1 at the position corresponding to the position of the limiting plate 5.

[0027] The positioning plates 44 on both sides of the distribution beam 1 are inserted into the positioning ports 6 on both sides to restrict the movement of the limiting plate 5. The positioning plate 44 is arc-shaped on one side of the positioning port 6. The movable part 49 is slidably set inside the opening 410. The bolt head 411 is adapted to the fixed cylinder 41, and the bayonet 413 is adapted to the limiting plate 5.

[0028] When the bridge deck 2 needs to be installed on several fixed sets of distribution beams 1, the limiting plate 5 fixed on the lower side of the bridge deck 2 is inserted into the bayonet 413. Through the cooperation between the limiting plate 5 and the bayonet 413, the bridge deck 2 is restricted from moving in all directions. The limiting plate 5 continues to move downward and contacts the limiting member positioning plate 44, pushing the limiting member positioning plate 44 to rotate along the steering roller 43 in the fixed cylinder 41. At the same time, the rotating shaft 45 pushes the movable part 49 to slide on the movable rod 48. The movable part 49 is pushed upward and squeezes the second spring 412. While the limiting member positioning plate 44 rotates, it retracts inward to the steering roller 43 until the limiting member positioning plate 44 is aligned with the positioning port 6. 412 pushes the movable part 49 in the opposite direction, so that the positioning plate 44 of the limiting part is inserted into the positioning port 6, forming a limiting constraint on the limiting plate 5. This avoids complicated disassembly and assembly procedures, low efficiency, inability to replace individual panels after splicing, and difficulty in removal due to narrow gaps, poor turnover, and difficulty in meeting the needs of efficient on-site construction. During disassembly, the threaded cover 313 is opened, and the bolt head 411 is operated with a tool to drive the threaded rod 47 to rotate, thereby driving the movable part 49 to move downward. The movable part 49 drives the positioning plates 44 of the limiting parts on both sides to tilt upward, releasing their locking restriction on the limiting plate 5. This can achieve rapid disassembly of the overall structure and also complete the independent disassembly and replacement of a single bridge panel 2.

[0029] Working principle: When the bridge deck 2 needs to be installed on several fixed sets of distribution beams 1, the limiting plate 5 fixed on the lower side of the bridge deck 2 is inserted into the bayonet 413. Through the cooperation between the limiting plate 5 and the bayonet 413, the bridge deck 2 is restricted from moving in all directions. The limiting plate 5 continues to move downward and contacts the limiting member positioning plate 44, pushing the limiting member positioning plate 44 to rotate along the steering roller 43 in the fixed cylinder 41. At the same time, the rotating shaft 45 pushes the movable part 49 to slide on the movable rod 48. The movable part 49 is pushed upward and squeezes the second spring 412. While the limiting member positioning plate 44 rotates, it retracts inward to the steering roller 43 until the limiting member positioning plate 44 is aligned with the positioning port 6. Spring 412 pushes the movable part 49 in the opposite direction, causing the positioning plate 44 of the limiting part to be inserted into the positioning port 6, forming a limiting constraint on the limiting plate 5. This avoids complicated and inefficient disassembly and assembly procedures, the inability to replace individual panels after splicing, and the difficulty in removing panels due to narrow gaps, resulting in poor turnover and difficulty in meeting the needs of efficient on-site construction. During disassembly, the threaded cover 313 is opened, and the bolt head 411 is manipulated with a tool to rotate the threaded rod 47, thereby driving the movable part 49 to move downward. The movable part 49 causes the positioning plates 44 of the limiting parts on both sides to tilt upward, releasing their locking restriction on the limiting plate 5. This allows for quick disassembly of the overall structure as well as independent disassembly and replacement of individual bridge panels 2. In addition, by fastening the groove cover 315 to the outside of the hexagonal groove 314, the hexagonal groove 314 can be shielded and protected, effectively reducing the accumulation and blockage of dirt. At the same time, the threaded cover 313 is used to shield and protect the threaded opening 316 on the outside of the positioning component 4, effectively preventing mud and dirt from entering and causing blockage and corrosion, extending the service life of the components. Moreover, the protective structure is compact and integrated, and can be installed and covered immediately without additional modification, making it suitable for harsh outdoor working conditions on construction sites. Secondly, after opening the threaded cover 313, the lifting ring 38 is pulled upward to disengage it from the spring clip 310. The first spring 35 can automatically pop the movable ring 34 and the lifting ring 38 out of the threaded opening 316. Under the gravity of the counterweight 39, the lifting ring 38 automatically maintains a vertical position after popping out, quickly establishing a lifting force point. This makes it easy for workers to use the vertical lifting ring 38 to lift and remove the single bridge panel 2 as a whole from the narrow panel splicing gap. When the lifting ring 38 is locked inside the spring clip 310, it can maintain a horizontal position without occupying operating space, making it convenient for tools to be inserted inside to adjust and control the positioning component 4.

The appropriate model is selected according to actual use, so it will not be explained in detail.
