Description

Technical Field

[0001] This invention relates to the field of load-bearing frame technology, specifically to a modular rotating beam load-bearing frame that can be disassembled and reused. Background Technology

[0002] In bridge construction, the rotating beam construction technique is an important technology, particularly suitable for crossing existing railways, highways, or rivers. The core of this technique involves pre-casting or assembling the main bridge structure along the extended line of the bridge axis or parallel to the obstacle, forming a complete T-shaped or box-shaped rotating body. Using hinge devices pre-installed on the pier foundations, a hydraulic or mechanical traction system rotates the entire beam structure, weighing thousands or even tens of thousands of tons, by a specific angle, ultimately positioning it precisely on the designed bridge axis for closure. This method minimizes interference with traffic flow below, effectively reduces safety risks, and significantly shortens the construction period, thus finding widespread application in urban interchanges and overpasses.

[0003] However, existing construction technologies for rotating beams, especially in terms of their load-bearing frame systems, still have some significant limitations. Traditional load-bearing frames mostly employ on-site welding or fixed embedded structures, which are tightly integrated with the concrete beam and difficult to separate, essentially becoming disposable consumables. This approach not only leads to the waste of large amounts of steel after a single use, resulting in resource waste and increased costs, but also makes the construction process cumbersome. The erection and dismantling of the support structure are time-consuming and labor-intensive, and the system has poor adaptability, making it difficult to flexibly meet the engineering needs of different spans, curvatures, or complex terrain conditions. In addition, fixed frames lack effective adjustable mechanisms and standardized connection interfaces, limiting the ability to fine-tune the structural posture during rotation, which may increase the risk of positioning deviations. At the same time, their bulky structure also brings many inconveniences to transportation, warehousing, and on-site management. These shortcomings restrict the further promotion of rotating beam technology and the improvement of its overall benefits. Therefore, we propose a modular rotating beam load-bearing frame that can be disassembled and reused. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a modular rotating beam load-bearing frame that can be disassembled and reused, which can realize rapid disassembly and assembly, flexible height adjustment, reuse and stable load bearing, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular rotating beam load-bearing frame that can be disassembled and reused, comprising a square tube and an adjustment assembly;

[0006] Square tube: A slide bar is slidably connected inside. A fixing frame is fixed on the side of the slide bar. The lower side of the fixing frame is in contact with the upper side of the square tube. A first connecting component is installed on the upper side of the slide bar. A support component is installed on the side of the fixing frame. A second connecting component is installed on the right end of the support component. A fixing component and a tensioning component are installed on the upper end of the side of the slide bar. The fixing component and the tensioning component are connected.

[0007] Adjustment assembly: includes a support plate, a support frame, a limiting rod, a threaded rod, and a connecting frame. An opening is formed on the lower side of the square tube, and a support plate is fixed inside the opening. Two corresponding support frames are fixed on the left and right sides of the support plate. Two corresponding connecting frames are fixed on the left and right sides of the fixing frame. A threaded hole is formed on the upper side of the right connecting frame, and a threaded rod is threaded into the threaded hole. The lower end of the threaded rod is rotatably connected to the upper side of the support plate, and the upper end of the threaded rod is rotatably connected to the upper side inside the right support frame. A limiting hole is formed on the left side of the left connecting frame, and a limiting rod is slidably connected inside the limiting hole. The limiting rod is fixed inside the support frame on the left side. The lower end of the threaded rod surface is equipped with an actuating component. Through the coordinated design of the square tube and the adjustment component, the height of the frame can be flexibly adjusted and the overall stability controlled. The sliding connection structure between the slider and the fixed frame allows for quick adjustment of the vertical support height of the frame during construction, adapting to the construction needs of rotating beams with different spans or slopes. The combination of the threaded rod and the limiting rod in the adjustment component can precisely control the lifting and lowering of the frame and prevent deflection, ensuring the accurate alignment and safe load-bearing of the load-bearing system during rotation. This design is particularly suitable for temporary support scenarios that require multiple disassemblies and reuses, effectively reducing construction costs and material waste.

[0008] Furthermore, the actuating assembly includes a rotating ring and an anti-slip ring. The rotating ring is fixed to the lower end of the threaded rod surface, and the anti-slip ring is fixed to the circumferential surface of the rotating ring. The actuating assembly provides a force-saving and anti-slip point for the rotation of the threaded rod through the cooperation of the rotating ring and the anti-slip ring, which makes it convenient for construction personnel to quickly adjust the height of the frame when working in confined spaces or at heights, thereby improving operational efficiency and safety.

[0009] Furthermore, the first connecting assembly includes a retaining strip, a cross rod, and an internally threaded tube. A square groove is formed on the upper side of the sliding strip, and a retaining strip is engaged inside the square groove. A cross rod is fixed on the upper side of the retaining strip. The edge of the cross rod has evenly distributed threaded grooves. The right end of the cross rod surface is threadedly connected to the internally threaded tube. The first connecting assembly achieves rapid assembly and fixation of the transverse members through the retaining strip and the cross rod engagement structure. The threaded connection between the internally threaded tube and the end of the cross rod can expand the transverse span of the frame or connect auxiliary support components, enhancing the adaptability of the modular design and meeting the requirements of different bridge widths or load distributions.

[0010] Furthermore, the fixing component includes an L-shaped fixing tube, a connecting groove, a clamp, a first spring, a pull rope, and a slot. The upper side of the slide bar has four corresponding guide holes. An L-shaped fixing tube is fixed inside each guide hole. A connecting groove is formed on the end face of the L-shaped fixing tube inside the guide hole. A clamp is slidably connected inside the connecting groove. A first spring is fixed to the end face of the clamp and is fixed inside the connecting groove. A pull rope is slidably connected inside the L-shaped fixing tube. The upper end of the pull rope is fixed to the end face of the clamp. Four corresponding slots are formed on the side of the slide bar. The clamp engages with the corresponding slot. The fixing component utilizes a spring self-locking mechanism between the clamp and the slot to achieve automatic locking and rapid release of the slide bar. The linkage design between the pull rope and the first spring ensures that the connection point remains tightly fitted under high-frequency vibration or load changes, preventing structural instability due to loosening during rotation.

[0011] Furthermore, the pulling assembly includes an external threaded ring, a slip ring, and an internal threaded ring. The upper end of the slide bar surface is fixed with an external threaded ring, and the surface of the external threaded ring is threadedly connected to an internal threaded ring. The upper end of the internal threaded ring is rotatably connected to a slip ring, which is sleeved on the surface of the slide bar. The lower ends of the four pull ropes are all fixed to the upper ends of the slip rings. The external threaded ring is located above the fixed frame. The pulling assembly drives the slip ring to move up and down through the threaded transmission between the external threaded ring and the internal threaded ring, thereby synchronously controlling the tension of multiple pull ropes and realizing the collective unlocking or locking of the clamps, greatly improving the disassembly and assembly efficiency, and is especially suitable for batch operations of large frames.

[0012] Furthermore, the support assembly includes a support tube, a pull head, a slide rod, a connecting groove, and a second spring. Four corresponding support tubes are fixed on the side of the fixed frame. Two corresponding connecting grooves are formed on the circumferential surface of each support tube. A connecting hole is formed inside the connecting groove, and a slide rod is slidably connected inside the connecting hole. A pull head is set inside the connecting groove. A second spring is sleeved on the circumferential surface of the slide rod. One end of the second spring is fixed inside the connecting groove, and the other end of the second spring is fixed to the end face of the pull head. The support assembly achieves rapid extension and retraction positioning of the support tube through the elastic locking structure of the slide rod and the second spring, which facilitates the adjustment of the lateral support range of the frame. The design of the pull head allows for manual unlocking, which can meet the needs of frequent size adjustments during construction.

[0013] Furthermore, the second connecting component includes a connecting rod and a support groove. The connecting rod is slidably connected inside the support tube on the right side. The connecting rod has evenly distributed support grooves on its circumferential surface. The two sliding rods on the right side are engaged inside the corresponding support grooves. The second connecting component utilizes the insertion and engagement of the connecting rod and the support groove to extend or adjust the angle of multiple support tubes, thereby enhancing the adaptability of the frame in complex terrain, such as crossing obstacles or connecting irregular piers.

[0014] Furthermore, four corresponding mounting plates are fixed on the front and rear sides of the support plate. The mounting plates have mounting holes on their upper sides. The mounting plates and mounting holes provide a standardized connection interface between the frame and the foundation or transition pier. The frame can be quickly installed and anchored on site by bolt fixing, ensuring the overall stability before rotation.

[0015] Furthermore, the front side of the square tube is provided with evenly distributed support holes, and the lower end of the surface of the slide bar is provided with fastening holes. Connecting bolts are provided inside the fastening holes and the corresponding support holes. The combination of the connecting bolts and the support holes is used to fix the final position of the slide bar in the square tube, prevent accidental slippage caused by load changes during construction, and provide double insurance when bearing weight.

[0016] Furthermore, a groove is provided on the lower side of the support plate, and an anti-slip plate is fixed inside the groove. The anti-slip plate increases the friction between the support plate and the foundation surface, preventing the frame from undergoing horizontal displacement during rotation. It is especially suitable for soft foundation or sloping conditions with a high risk of slippage.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This modular rotating beam load-bearing frame, which can be disassembled and reused, has the following advantages:

[0018] By designing the framework as a standardized module consisting of square tubes, sliding bars, and fixed frames, supplemented by detachable connection mechanisms such as first and second connecting components, the complete disassembly and recycling of the framework after construction is achieved. These components, after inspection and maintenance, can be reused in new projects multiple times, greatly increasing the turnover rate of materials and reducing steel consumption and construction waste generation at the source, demonstrating significant green environmental protection and economic benefits. By adjusting the precise fit between the threaded rods and limit rods in the components, the lifting and lowering of the sliding bars can be easily controlled, thereby precisely adjusting the support height of the entire framework to adapt to different beam spans and site slopes. Simultaneously, the support components can... With its flexible and retractable design, the second connecting component allows for expansion of the lateral support range. This comprehensive adjustment capability ensures that the frame can precisely match complex construction conditions and the fine-tuning requirements of posture during rotation, effectively improving construction quality and safety. By setting up a fixing component that uses springs to achieve automatic locking of the clamps, and a pulling component that uses threaded transmission to achieve synchronous collective unlocking of multiple clamps, rapid assembly and disassembly of lateral members is achieved. This user-friendly design avoids the need for tedious individual operations at each connection point in traditional methods, greatly simplifying the assembly and disassembly process, shortening the construction period, and reducing labor intensity, providing a strong guarantee for the rapid progress of the project.

Two corresponding support frames 32 are fixed on the left and right sides of the support plate 31. Two corresponding connecting frames 35 are fixed on the left and right sides of the fixing frame 13. A threaded hole is provided on the upper side of the right connecting frame 35, and a threaded rod 34 is threadedly connected inside the threaded hole. The lower end of the threaded rod 34 is rotatably connected to the upper side of the support plate 31, and the upper end of the threaded rod 34 is rotatably connected to the upper side inside the right support frame 32. A limiting hole is provided on the left side of the left connecting frame 35, and a limiting rod is slidably connected inside the limiting hole. 33. The limiting rod 33 is fixed inside the support frame 32 on the left side. The lower end of the threaded rod 34 is equipped with an actuating component 4. Through the coordinated design of the square tube 1 and the adjusting component 3, the height of the skeleton can be flexibly adjusted and the overall stability can be controlled. The sliding connection structure between the slide bar 2 and the fixed frame 13 allows for quick adjustment of the vertical support height of the skeleton during construction, adapting to the construction needs of rotating beams with different spans or slopes. The combination of the threaded rod 34 and the limiting rod 33 in the adjusting component 3 can precisely control the lifting and lowering of the skeleton and prevent deflection, ensuring the accurate alignment and safe load-bearing of the load-bearing system during the rotation process. This design is particularly suitable for temporary support scenarios that require multiple disassembly and reuse, effectively reducing construction costs and material waste.

[0029] The actuating assembly 4 includes a rotating ring 41 and an anti-slip ring 42. The rotating ring 41 is fixed to the lower end of the surface of the threaded rod 34, and the anti-slip ring 42 is fixed to the circumferential surface of the rotating ring 41. The actuating assembly 4 provides a force-saving and anti-slip force application point for the rotation operation of the threaded rod 34 through the cooperation of the rotating ring 41 and the anti-slip ring 42, which makes it convenient for construction personnel to quickly adjust the height of the frame when working in a confined space or at height, thereby improving operational efficiency and safety.

[0030] The first connecting component 5 includes a retaining strip 51, a cross rod 52, and an internally threaded tube 53. A square groove is provided on the upper side of the slide bar 2, and the retaining strip 51 is engaged inside the square groove. The cross rod 52 is fixed on the upper side of the retaining strip 51. The edge of the cross rod 52 is provided with evenly distributed threaded grooves. The right end of the surface of the cross rod 52 is threadedly connected to the internally threaded tube 53. The first connecting component 5 achieves rapid assembly and fixation of the transverse members through the engaging structure of the retaining strip 51 and the cross rod 52. The threaded connection between the internally threaded tube 53 and the end of the cross rod 52 can expand the transverse span of the frame or connect auxiliary support components, enhance the adaptability of the modular design, and meet the requirements of different bridge widths or load distributions.

[0031] The fixing component 6 includes an L-shaped fixing tube 61, a connecting groove 62, a clamp 63, a first spring 64, a pull rope 65, and a locking groove 66. Four corresponding guide holes are provided on the upper side of the slide bar 2. An L-shaped fixing tube 61 is fixed inside each guide hole. A connecting groove 62 is provided on the end face of the L-shaped fixing tube 61 inside the guide hole. A clamp 63 is slidably connected inside the connecting groove 62. A first spring 64 is fixed on the end face of the clamp 63 and is fixed inside the connecting groove 62. The L-shaped fixing tube 61... An internal sliding connection includes a pull rope 65, the upper end of which is fixed to the end face of the clamp head 63. Four corresponding slots 66 are provided on the side of the clamping strip 51. The clamp head 63 is engaged in the corresponding slot 66. The fixing component 6 utilizes the spring self-locking mechanism between the clamp head 63 and the slot 66 to achieve automatic locking and quick release of the clamping strip 51. The linkage design between the pull rope 65 and the first spring 64 ensures that the connection point remains tightly fitted under high-frequency vibration or load changes, preventing structural instability caused by loosening during rotation.

[0032] The pulling assembly 7 includes an external threaded ring 71, a slip ring 72, and an internal threaded ring 73. The external threaded ring 71 is fixed to the upper end of the surface of the slide bar 2. The surface of the external threaded ring 71 is threadedly connected to the internal threaded ring 73. The upper end of the internal threaded ring 73 is rotatably connected to the slip ring 72. The slip ring 72 is sleeved on the surface of the slide bar 2. The lower ends of the four pull ropes 65 are all fixed to the upper ends of the slip ring 72. The external threaded ring 71 is located above the fixed frame 13. The pulling assembly 7 drives the slip ring 72 to move up and down through the thread transmission between the external threaded ring 71 and the internal threaded ring 73, thereby synchronously controlling the tension of multiple pull ropes 65, realizing the collective unlocking or locking of the clasp 63, greatly improving the disassembly and assembly efficiency, and is especially suitable for batch operations of large frames.

[0033] The support assembly 8 includes a support tube 81, a pull head 82, a slide rod 83, a connecting groove 84, and a second spring 85. Four corresponding support tubes 81 are fixed on the side of the fixed frame 13. Two corresponding connecting grooves 84 are opened on the circumferential surface of the support tube 81. A connecting hole is opened inside the connecting groove 84, and a slide rod 83 is slidably connected inside the connecting hole. A pull head 82 is set inside the connecting groove 84. A second spring 85 is sleeved on the circumferential surface of the slide rod 83. One end of the second spring 85 is fixed inside the connecting groove 84, and the other end of the second spring 85 is fixed on the end face of the pull head 82. The support assembly 8 realizes the rapid extension and retraction positioning of the support tube 81 through the elastic snap-fit ​​structure of the slide rod 83 and the second spring 85, which facilitates the adjustment of the lateral support range of the frame. The design of the pull head 82 allows manual unlocking to meet the needs of frequent size adjustments during construction.

[0034] The second connecting component 9 includes a connecting rod 91 and a support groove 92. The connecting rod 91 is slidably connected inside the support tube 81 on the right side. The support groove 92 is evenly distributed on the circumferential surface of the connecting rod 91. The two sliding rods 83 on the right side are engaged inside the corresponding support grooves 92. The second connecting component 9 uses the insertion and cooperation of the connecting rod 91 and the support groove 92 to realize the extension or angle adjustment of multiple support tubes 81, thereby enhancing the adaptability of the frame in complex terrain, such as crossing obstacles or connecting irregular piers.

[0035] Among them, four corresponding mounting plates 10 are fixed on the front and rear sides of the support plate 31. The mounting plate 10 has mounting holes 11 on its upper side. The mounting plate 10 and the mounting holes 11 provide a standardized connection interface between the frame and the foundation or transition pier. The frame can be quickly installed and anchored on site by bolt fixing, ensuring the overall stability before rotation.

[0036] Wherein: the front side of the square tube 1 is provided with evenly distributed support holes 14, and the lower end of the surface of the slide bar 2 is provided with fastening holes. The fastening holes and the corresponding support holes 14 are provided with connecting bolts 12. The connecting bolts 12 and the support holes 14 are combined to fix the slide bar 2 in the final position in the square tube 1, prevent accidental sliding due to load changes during construction, and provide double insurance when bearing weight.

[0037] Among them, the lower side of the support plate 31 has a groove, and the anti-slip plate 15 is fixed inside the groove. The anti-slip plate 15 increases the friction between the support plate 31 and the foundation surface, preventing the frame from undergoing horizontal displacement during the rotation process. It is especially suitable for soft foundation or sloping conditions with high risk of slippage.

[0038] The working principle of the modular rotating beam load-bearing frame that can be disassembled and reused according to the present invention is as follows: Through the coordinated operation of the square tube 1 and the adjustment component 3, the frame can be flexibly adjusted in height and stably supported. Specifically, the operator first rotates the rotating ring 41 of the actuating component 4, using the anti-slip ring 42 to provide a force-saving grip, driving the threaded rod 34 to rotate. Since the threaded rod 34 cooperates with the threaded hole of the right connecting frame 35, and is constrained by the support plate 31 and the support frame 32, it drives the fixed frame 13 and the slide bar 2 to slide and rise inside the square tube 1. At the same time, the limiting rod 33 slides in the limiting hole of the left connecting frame 35 to prevent deflection and ensure vertical movement. After the height is adjusted, the connecting bolt 12 is inserted into the fastening hole of the slide bar 2 and the support hole 14 of the square tube 1 for fixation, providing double insurance. Then, the first connecting component 5 is used for lateral expansion, and the locking strip 51 is inserted into the square groove of the slide bar 2. The threaded groove on the cross rod 52 allows... The internal threaded tube 53 is connected to extend the span; the fixing component 6 operates automatically, the first spring 64 pushes the clamp 63 to engage with the groove 66 of the clamp strip 51 to lock it, and the pull rope 65 connects the clamp 63; when disassembly is required, the pulling component 7 is operated, the internal threaded ring 73 is rotated and moves along the external threaded ring 71, driving the slip ring 72 to pull down the pull rope 65, and simultaneously retracting all the clamps 63 to release the lock; the support component 8 allows lateral adjustment, when the pull head 82 is pulled, the second spring 85 is compressed, causing the slide rod 83 to retract from the connecting groove 84, which facilitates the extension and retraction of the support tube 81; the second connecting component 9 engages with the slide rod 83 through the support groove 92 of the connecting rod 91 to achieve multi-segment extension; the entire frame is anchored to the foundation with bolts through the mounting holes 11 of the mounting plate 10, and the anti-slip plate 15 increases the bottom friction to prevent slippage; the whole process emphasizes modular disassembly and assembly, and when reused, it can be quickly disassembled and reassembled by simply reversing the operation, adapting to different engineering needs.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
