Description

Technical Field

[0001] This invention relates to the field of bridge engineering construction technology, specifically to a rapid composite steel structure support for cap beam construction and its assembly method. Background Technology

[0002] In the field of bridge cap beam construction, steel structure supports, with their advantages of high strength, good load-bearing capacity, and reusability, have become the core support equipment in the cap beam pouring, rebar tying, and formwork support processes. They are widely used in the construction of pier cap beams for highways, municipal viaducts, and railway bridges. Currently, most mainstream steel frame structures for cap beam construction on the market adopt fixed clamping support structures to clamp and fix bridge piers, thereby completing the positioning and installation of the supports and providing a stable support platform for cap beam construction.

[0003] In existing technologies, the clamping mechanisms of steel structure supports are mostly customized fixed structures with pre-set fixed dimensions for clamping holes and clamping spacing. They can only clamp and fix beams, columns, and piers with a single fixed diameter and fixed shape, and cannot adapt to the construction needs of beams, columns, and piers with different diameters and specifications. For piers of different sizes, steel structure supports of corresponding specifications need to be customized separately, which not only significantly increases the cost of steel procurement and customization, but also results in a large number of steel structure components being idle and piled up, with low resource utilization and poor project economics.

[0004] Furthermore, most existing steel structure supports and matching guardrails for cap beams are assembled using a combination of bolt fastening and on-site welding. Bolt connections require manual alignment, drilling, and tightening of multiple sets of bolts, making the assembly and disassembly process cumbersome and involving a large amount of work at height. Welding, on the other hand, is irreversible, making it difficult to disassemble components after assembly. Additionally, traditional integrated steel structure supports and guardrails are fixed welded structures, meaning the guardrails and supporting steel frames cannot be disassembled or reassembled individually, making overall transport and transfer difficult. The setup in the early stages of construction and the dismantling in the later stages are time-consuming, resulting in low efficiency and severely delaying the cap beam construction schedule. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rapid-assembly combined steel structure support for cap beam construction and a method for its assembly, solving the problems of poor ease of assembly and disassembly of existing steel structure supports and poor adaptability of clamping mechanisms.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid-assembly combined steel structure support for cap beam construction, comprising beams and columns, and a construction platform. The outer wall of the beams and columns is provided with clamping components, which are used to provide support for the steel structure support. The construction platform is provided with quick-release components, which are used to quickly assemble the steel structure support. The clamping assembly includes an adjusting ring and a mounting ring. The adjusting ring has multiple telescopic grooves evenly distributed on it, and a telescopic block is slidably connected in the telescopic groove. The mounting ring has a mounting groove, and a rotating plate is rotatably connected in the mounting groove. The rotating plate has multiple arc-shaped grooves evenly distributed on it. A pull rod is fixedly connected to one end of the telescopic block near the rotating plate, and the pull rod is slidably connected to the arc-shaped groove. The quick-release assembly includes sleeves installed at the four corners of the construction platform. The outer wall of the sleeve has a sliding groove, and a slider is slidably connected in the sliding groove. A slip ring is slidably connected to the outer wall of the sleeve, and the slip ring is fixedly connected to the slider. The sleeve has multiple rolling grooves along its circumference, and ball bearings are installed in the rolling grooves. An insert rod is slidably inserted into the sleeve, and a slot is provided on the insert rod, with the ball bearings engaging with the slot.

[0007] Preferably, two slides are symmetrically installed on the end of the adjusting ring near the construction platform, two adjusting grooves are symmetrically opened on the construction platform, and the slides are slidably connected to the adjusting grooves. Multiple insertion holes are evenly opened on the end of the construction platform near the adjusting ring.

[0008] Preferably, a support plate is fixedly connected to one end of the carriage near the adjustment groove, a spline rod is slidably connected to the support plate, a compression spring is sleeved on the outer wall of the spline rod, and the spline rod is inserted into the socket.

[0009] Preferably, a limiting ring is fixedly connected to the outer wall of the sleeve, and a return spring is sleeved on the outer wall of the sleeve, with the return spring positioned between the limiting ring and the slip ring.

[0010] Preferably, a toothed ring is fixedly connected to the end of the rotating plate away from the adjusting ring, and a ratchet ring is fixedly connected to the end of the toothed ring away from the rotating plate.

[0011] Preferably, a fixing frame is fixedly connected to the side wall of the adjusting ring, a rotating motor is fixedly connected to the fixing frame, and a worm gear is fixedly connected to the output end of the rotating motor.

[0012] Preferably, the ends of each pair of insert rods furthest from the sleeve are fixedly connected to a second guardrail, and the two ends of the second guardrail are snapped with the first guardrail.

[0013] Preferably, a shaft is rotatably connected to the fixed frame, a locking block is fixedly connected to the outer wall of the shaft, a spring is fixedly connected to the shaft, the end of the spring away from the shaft is fixedly connected to the fixed frame, and the locking block engages with the ratchet ring.

[0014] Preferably, the construction platform has multiple fixing holes evenly distributed at the end away from the adjusting ring.

[0015] A method for assembling a rapid composite steel structure support for cap beam construction includes the following steps: S1. Based on the distance between the two beams and columns, pull the spline rod out of the socket to release the lock on the adjusting ring. Adjust the distance between the two adjusting rings along the adjusting groove opened on the construction platform so that the distance between the adjusting rings matches the distance between the beams and columns. After the adjusting ring is adjusted, release the spline rod and the compression spring pushes the spline rod into the socket to limit the adjusting ring. S2. The hoisting construction platform moves the adjusting ring along the outer wall of the beam and column. When the construction platform moves to the predetermined height, the rotating motor drives the worm gear to rotate, which in turn drives the gear ring and rotating plate to rotate synchronously. The arc groove drives the tie rod to move, which in turn drives the telescopic block to move along the telescopic groove, causing multiple arc plates to approach the beam and column and abut against it. At the same time as the gear ring rotates, the ratchet ring rotates synchronously. The ratchet teeth of the ratchet ring push the locking block to rotate around the shaft. When the gear ring stops rotating, the locking block abuts against the teeth of the ratchet ring to prevent the ratchet ring from rotating in the opposite direction and causing the adjusting ring to fail to fix. S3. After the construction platform is installed, push the sliding ring along the sliding groove toward the limit ring to move the sliding ring away from the rolling groove, release the locking of the sliding ring on the ball, fully insert the insert rod into the sleeve, move the slot on the insert rod to the rolling groove, release the sliding ring, and the return spring pushes the sliding ring to move in the opposite direction along the sliding groove, pushing the ball into the slot, completing the installation of the second guardrail, and snapping the first guardrail and the second guardrail together.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, an adjustable clamping and positioning mechanism is set up, which abandons the traditional fixed-diameter clamping structure. It can flexibly adjust the clamping distance according to the diameter and cross-sectional specifications of bridge piers and beams, and can be adapted to the construction of beams and columns with different cross-sections and diameters, such as circular and rectangular ones. There is no need to customize brackets for different piers and columns, which greatly reduces the cost of custom processing of steel structures, reduces the idle rate of components, improves the utilization rate of steel resources, and is suitable for various bridge engineering construction scenarios, with a wider range of applications.

[0017] 2. This invention adopts a modular rapid assembly structure, eliminating the traditional method of fixing with a large number of bolts and on-site welding. It uses a snap-fit ​​and plug-in combination connection structure, which does not require professional welding equipment and avoids the problems of steel deformation, oxidation and corrosion caused by high welding temperatures. The disassembly process does not require flame cutting and will not cause secondary damage to the components. There is no need to manually tighten a large number of bolts one by one. Assembly and alignment are simple and convenient. At the same time, the main body of the support and the guardrail adopt a split combination structure, which can be disassembled and assembled separately and freely combined. The components are small in size after disassembly and are easy to transport and transfer, which greatly simplifies the erection and disassembly process, reduces the time spent working at height, effectively shortens the construction period of the cap beam, and reduces labor construction costs.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] refer to Figures 1-7The illustrated rapid-assembly combined steel structure support for cap beam construction includes beams / columns 1 and a construction platform 3. Clamping components are installed on the outer wall of the beams / columns 1 to provide support for the steel structure support. Quick-release components are installed on the construction platform 3 for rapid assembly of the steel structure support. A specific embodiment is shown below: Example 1 The clamping assembly includes an adjusting ring 2 and a mounting ring 29. The adjusting ring 2 has multiple telescopic grooves 28 evenly distributed, and a telescopic block 26 is slidably connected in the telescopic grooves 28. The mounting ring 29 has a mounting groove 33, and a rotating plate 30 is rotatably connected in the mounting groove 33. The rotating plate 30 has multiple arc-shaped grooves 31 evenly distributed. A pull rod 32 is fixedly connected to the end of the telescopic block 26 near the rotating plate 30, and the pull rod 32 is slidably connected to the arc-shaped groove 31. The construction platform 3 has multiple fixing holes 6 evenly distributed at the end away from the adjusting ring 2. A toothed ring 20 is fixedly connected to the end of the rotating plate 30 away from the adjusting ring 2, and a ratchet ring 21 is fixedly connected to the end of the toothed ring 20 away from the rotating plate 30. A fixing frame 34 is fixedly connected to the side wall of the adjusting ring 2, and a rotating motor 19 is fixedly connected to the fixing frame 34. A worm gear 38 is fixedly connected to the output end of the rotating motor 19.

[0022] The rotating motor 19 drives the worm gear 38 to rotate, and the worm gear 38 meshes with the teeth of the gear ring 20, thereby driving the gear ring 20 to rotate along the mounting groove 33. Since the gear ring 20 is fixedly connected to the rotating plate 30, the rotating plate 30 simultaneously drives multiple telescopic blocks 26 to move along the telescopic groove 28, so that the arc-shaped plate 27 installed at the end of the telescopic block 26 abuts against the outer wall of the beam and column 1. The contact end face of the arc-shaped plate 27 with the beam and column 1 is provided with an anti-slip rubber pad to increase the friction between the arc-shaped plate 27 and the beam and column 1.

[0023] Example 2 Two slides 22 are symmetrically installed on the end of the adjusting ring 2 near the construction platform 3. Two adjusting grooves 17 are symmetrically opened on the construction platform 3, and the slides 22 are slidably connected to the adjusting grooves 17. Multiple insertion holes 18 are evenly opened on the end of the construction platform 3 near the adjusting ring 2. A support plate 23 is fixedly connected to the end of the slide 22 near the adjusting groove 17. A spline rod 24 is slidably connected to the support plate 23. A compression spring 25 is sleeved on the outer wall of the spline rod 24, and the spline rod 24 is inserted into the insertion hole 18. A shaft 35 is rotatably connected to the fixed frame 34. A locking block 36 is fixedly connected to the outer wall of the shaft 35. A spring 37 is fixedly connected to the shaft 35. The end of the spring 37 away from the shaft 35 is fixedly connected to the fixed frame 34, and the locking block 36 is engaged with the ratchet ring 21.

[0024] Based on the distance between the two beams and columns 1, the spline rod 24 is pulled out from the insertion hole 18 to release the locking of the adjusting ring 2. The distance between the two adjusting rings 2 is adjusted along the adjusting groove 17 opened on the construction platform 3 so that the distance between the adjusting rings 2 matches the distance between the beams and columns 1. After the adjusting rings 2 are adjusted, the spline rod 24 is released, and the compression spring 25 pushes the spline rod 24 into the insertion hole 18 to limit the adjusting rings 2, so that the two adjusting rings 2 are symmetrically distributed, thereby raising the construction platform. To ensure stability, during the process of the gear ring 20 clamping the arc plate 27 and the beam column 1, the ratchet ring 21 rotates synchronously. The ratchet teeth of the ratchet ring 21 push the locking block 36 to rotate around the shaft 35. During this process, the locking block 36 does not engage with the ratchet teeth of the ratchet ring 21. When the gear ring 20 stops rotating, the spring 37 drives the shaft 35 to rotate, and the locking block 36 engages with the teeth of the ratchet ring 21, preventing the ratchet ring 21 from rotating in the opposite direction and causing the adjusting ring 2 to fail to stay in place, thus improving the safety of the device.

[0025] Example 3 The quick-release assembly includes sleeves 7 installed at the four corners of the construction platform 3. The outer wall of the sleeve 7 has a sliding groove 10, and a slider 16 is slidably connected in the sliding groove 10. A slip ring 8 is slidably connected to the outer wall of the sleeve 7, and the slip ring 8 is fixedly connected to the slider 16. The sleeve 7 has multiple rolling grooves 13 along its circumference, and a ball bearing 14 is installed in the rolling groove 13. A rod 9 is slidably inserted into the sleeve 7, and a slot 15 is opened on the rod 9, and the ball bearing 14 is engaged with the slot 15. A limit ring 11 is fixedly connected to the outer wall of the sleeve 7. A return spring 12 is sleeved on the outer wall of the sleeve 7 and is located between the limit ring 11 and the slip ring 8. A second guardrail 5 is fixedly connected to the end of every two rods 9 away from the sleeve 7. The two ends of the second guardrail 5 are engaged with the first guardrail 4.

[0026] After the construction platform 3 is installed, push the sliding ring 8 along the sliding groove 10 toward the limiting ring 11 to move the sliding ring 8 away from the rolling groove 13, release the locking of the sliding ring 8 onto the ball 14, fully insert the insert rod 9 into the sleeve 7, move the slot 15 on the insert rod 9 to the rolling groove 13, release the sliding ring 8, and the return spring 12 pushes the sliding ring 8 to move in the opposite direction along the sliding groove 10, pushing the ball 14 into the slot 15, thus completing the installation of the second guardrail 5. Since the first guardrail 4 and the second guardrail 5 are plugged in, directly insert the pins at both ends of the first guardrail 4 into the insert rings installed at both ends of the second guardrail 5 to complete the assembly and fixation of the first guardrail 4 and the second guardrail 5. Multiple fixing holes 6 are provided on the construction platform 3 for fixing the bearing plate laid on the construction platform 3. The two ends of the bearing plate abut against the first guardrail 4 for limiting. The end of the bearing plate near the construction platform 3 is provided with a protruding rod that matches the fixing hole 6. The bearing plate can be flexibly laid according to the position of the beam and column 1, which not only improves the stability of the bearing plate, but also improves the convenience of disassembling and assembling the bearing plate.

[0027] A method for assembling a rapid composite steel structure support for cap beam construction includes the following steps: S1. Based on the distance between the two beams and columns 1, pull the spline rod 24 out of the insertion hole 18 to release the lock on the adjusting ring 2. Adjust the distance between the two adjusting rings 2 along the adjusting groove 17 opened on the construction platform 3 so that the distance between the adjusting rings 2 matches the distance between the beams and columns 1. After the adjusting ring 2 is adjusted, release the spline rod 24, and the compression spring 25 pushes the spline rod 24 into the insertion hole 18 to limit the adjusting ring 2. S2. The hoisting construction platform 3 moves the adjusting ring 2 along the outer wall of the beam and column 1. When the construction platform 3 moves to the predetermined height, the rotating motor 19 drives the worm gear 38 to rotate, which in turn drives the gear ring 20 and the rotating plate 30 to rotate synchronously. The arc groove 31 drives the tie rod 32 to move, which in turn drives the telescopic block 26 to move along the telescopic groove 28, which drives multiple arc plates 27 to approach the beam and column 1 and abut against it. While the gear ring 20 rotates, the ratchet ring 21 rotates synchronously. The ratchet teeth of the ratchet ring 21 push the locking block 36 to rotate around the shaft 35. When the gear ring 20 stops rotating, the locking block 36 abuts against the teeth of the ratchet ring 21 to prevent the ratchet ring 21 from rotating in the opposite direction and causing the adjusting ring 2 to fail to fix. S3. After the construction platform 3 is installed, push the sliding ring 8 along the sliding groove 10 toward the limiting ring 11 to move the sliding ring 8 away from the rolling groove 13, release the locking of the sliding ring 8 onto the ball 14, fully insert the insert rod 9 into the sleeve 7, move the slot 15 on the insert rod 9 to the rolling groove 13, release the sliding ring 8, and the return spring 12 pushes the sliding ring 8 to move in the opposite direction along the sliding groove 10, pushing the ball 14 into the slot 15, completing the installation of the second guardrail 5, and snapping the first guardrail 4 and the second guardrail 5 together.

[0028] The working principle of this invention is as follows: Based on the distance between the two beams and columns 1, the spline rod 24 is pulled out from the insertion hole 18 to release the locking of the adjusting ring 2. The distance between the two adjusting rings 2 is adjusted along the adjusting groove 17 opened on the construction platform 3 so that the distance between the adjusting rings 2 matches the distance between the beams and columns 1. After the adjusting rings 2 are adjusted, the spline rod 24 is released, and the compression spring 25 pushes the spline rod 24 into the insertion hole 18 to limit the adjusting ring 2. The construction platform 3 is hoisted so that the adjusting ring 2 moves along the outer wall of the beams and columns 1. When the construction platform 3 moves to the predetermined height, the rotating motor 19 drives the worm gear 38 to rotate, which in turn drives the gear ring 20 and the rotating plate 30 to rotate synchronously. The arc groove 31 drives the pull rod 32 to move, which in turn drives the telescopic block 26 to move along the telescopic groove 28, which drives multiple arc plates 27 to approach the beams and columns 1 and interact with them. The two rings abut against each other. When the gear ring 20 rotates, the ratchet ring 21 rotates synchronously. The ratchet teeth of the ratchet ring 21 push the locking block 36 to rotate around the shaft 35. When the gear ring 20 stops rotating, the locking block 36 abuts against the teeth of the ratchet ring 21 to prevent the ratchet ring 21 from rotating in the opposite direction and causing the adjusting ring 2 to fail to be fixed. After the construction platform 3 is installed, push the sliding ring 8 along the sliding groove 10 toward the limiting ring 11 to make the sliding ring 8 move away from the rolling groove 13, release the locking of the sliding ring 8 onto the ball 14, insert the rod 9 completely into the sleeve 7, and move the locking groove 15 on the rod 9 to the rolling groove 13. Release the return spring 12 of the sliding ring 8 to push the sliding ring 8 to move in the opposite direction along the sliding groove 10, push the ball 14 into the locking groove 15, and complete the installation of the second guardrail 5. The first guardrail 4 and the second guardrail 5 are then snapped together to improve the safety during construction.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
