Description

Technical Field

[0001] This invention belongs to the field of precast wall panel installation technology, specifically an auxiliary alignment and installation device and installation process for precast components. Background Technology

[0002] As a key vertical prefabricated component in prefabricated assembled buildings, the alignment and installation accuracy of prefabricated wall panels with the on-site embedded steel bars directly affects the overall structural stability and construction progress of the building. Currently, the installation of prefabricated wall panels generally adopts the hoisting method, which involves first suspending the wall panel above the embedded steel bars, and then slowly lowering it so that the embedded steel bars can be inserted into the reserved holes at the bottom of the wall panel to complete the assembly.

[0003] In existing technologies, the alignment of precast wall panels lacks specialized auxiliary tools, and on-site calibration mainly relies on manual labor. During construction, workers need to place reflectors on the ground for observation, and multiple people need to work together to support the wall panels and repeatedly adjust the hoisting posture. The positional fine-tuning depends entirely on the experience of senior workers, which is cumbersome and requires a large amount of manpower, significantly increasing the labor intensity on-site and resulting in low construction efficiency. In addition, manual alignment is easily affected by factors such as obstructed vision, hoisting sway, and human judgment errors, often resulting in misalignment and skew of the reserved holes and embedded steel bars, causing the steel bars to be bumped and deformed, and the wall panels to be installed off-center. Subsequent secondary chiseling and rework are required, which delays the construction period and reduces the assembly accuracy.

[0015] An auxiliary alignment and installation process for precast components, applicable to the aforementioned auxiliary alignment and installation device for precast components, comprising the following steps:

[0016] S1: Arrange the two sets of mounting brackets on both sides of the pre-embedded steel bars, rotate screw one to fine adjust the position of bracket one, start motor one to drive screw one, drive the two limit plates one to move synchronously to the center, cooperate with limit plate two to fit the pre-embedded steel bars, and at the same time make the guide sleeve one above limit plate one fit and cover the top of the steel bars to complete the installation benchmark positioning.

[0017] S2: Hoist the precast wall panel between the two clamping plates, start the motor three to drive the screw two to open the clamping plates, and the wall panel falls onto the support plate; then control the clamping plates to close in opposite directions, and form a bottom support enclosure through the cooperation of the support plate, support rod and groove, which stably supports the wall panel; adjust the screw two and screw three to adjust the position of guide sleeve two, and use the linkage structure of rack, gear and spring to judge by the impact sound to determine that rack two is engaged in the reserved hole of the wall panel, and complete the precise alignment of guide sleeve two with the reserved hole;

[0019] S4: The side plate is pushed by the electric push rod to laterally constrain and limit the wall panel. Then the adjustment mechanism is used to make the guide sleeve one and guide sleeve two move outward to avoid being directly below the reserved hole.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1-8 As shown in the embodiment of the present invention, an auxiliary alignment and installation device for prefabricated components includes a pair of mounting frames 1. Each of the mounting frames 1 has a sliding groove 15, and a mounting base 20 is slidably connected in the sliding groove 15. A bracket 4 is provided below the mounting base 20. A pair of limiting plates 9 and a second limiting plate 11 are provided on the bracket 4. A guide component 1 is provided on each of the limiting plates 9. A drive mechanism 1 is provided on the bracket 4. The drive mechanism 1 can drive the pair of limiting plates 9 to move. A bracket 26 is provided on one side of the mounting base 20. A pair of clamping plates 31 are provided on the bracket 26. A guide component 2 is provided on each of the clamping plates 31. The guide component 2 is adapted to the guide component 1. A drive mechanism 2 is provided on the bracket 26. The drive mechanism 2 can drive the pair of clamping plates 31 to move. A hoisting mechanism is provided at the top of the mounting frame 1. The hoisting mechanism can drive the mounting base 20 to move up and down. A lateral limiting component is provided at the top of the mounting base 20.

[0035] This application takes into account that, in most existing precast wall panel installations, the precast wall panel is first suspended above the embedded reinforcing bars during hoisting, and then lowered so that the embedded reinforcing bars can be inserted into the pre-drilled holes in the precast wall panel. However, due to the lack of dedicated positioning auxiliary tools, each time the precast wall panel is aligned with the reinforcing bars, workers need to place a mirror on the ground and repeatedly observe and adjust the position of the precast wall panel based on experience to complete the alignment of the pre-drilled holes with the embedded reinforcing bars. This installation method not only requires multiple workers to work together to control the posture of the wall panel and constantly correct its position, but also greatly increases the workload of the workers. The strength is limited, and the hole-making process relies entirely on worker experience, which can easily lead to installation errors and misalignment. To address this, this application sets up an installation frame 1 on each side of the pre-embedded steel bar. Through the drive mechanism 1, the limiting plate 1 9 can be moved to cooperate with the limiting plate 2 11, quickly completing the alignment and positioning of the installation frame 1 and the pre-embedded steel bar. The drive mechanism 2 drives the clamping plate 31 to clamp and limit the precast wall panel. In addition, the guide component 1 and guide component 2 are adapted to each other for guidance. At the same time, a lateral limiting component is added for lateral constraint. During the hoisting and falling process, the reserved hole and the pre-embedded steel bar can be automatically and accurately aligned with each other. The alignment accuracy is high and the error is small, avoiding misalignment installation problems.

[0036] The bottom of the mounting bracket 1 is threaded with a screw rod 2, one end of which is rotatably connected to the bracket 4. A pair of guide rods 3 are slidably connected to the mounting bracket 1, and both guide rods 3 are fixedly connected to the bracket 4.

[0037] The drive mechanism includes a motor 5, which is fixedly mounted on the outer wall of the bracket 4. A lead screw 6 is rotatably connected to the bracket 4. One end of the lead screw 6 extends to the outside of the bracket 4 and is fixedly connected to the output end of the motor 5. The lead screw 6 is provided with symmetrical reverse double threads. A pair of limiting blocks 8 are symmetrically connected to the lead screw 6 through a lead screw nut pair. The limiting blocks 8 are fixedly connected to the limiting plates 9. A limiting rod 7 is fixedly connected to the bracket 4. The limiting blocks 8 and the limiting rod 7 are slidably connected. A connecting plate 10 is fixedly connected to the center of the bracket 4. The connecting plate 10 is fixedly connected to the limiting plate 11. The limiting plate 11 is slidably connected to both limiting plates 9.

[0038] During operation, the screw 2 engages with the mounting bracket 1 via a threaded connection. Rotating the screw 2 allows for precise pushing and pulling to adjust the position of the bracket 4 and the limiting plate 11. The motor 5 drives the lead screw 6 to rotate, which in turn drives the limiting blocks 8 and the limiting plates 9 on both sides to move synchronously in opposite directions. The operator moves the mounting base 20 until the limiting plate 11 is parallel to and in contact with multiple steel bars on the ground, and the two limiting plates 9 clamp the two outer steel bars. This achieves the centering adjustment of the mounting bracket 1, facilitating quick alignment of the pre-embedded steel bar reference position and meeting the high-precision alignment and installation requirements of the precast wall panel.

[0039] The guide assembly includes a guide sleeve 13. The guide sleeve 13 is provided above the limiting plate 9. The guide sleeve 13 and the limiting plate 9 are fixedly connected by a support rod 12. The guide sleeve 13 is semi-circular in shape. The outer side of the top of the guide sleeve 13 is conical. A number of balls 14 are evenly arranged on the conical surface of the guide sleeve 13.

[0040] It should be noted that while the two limiting plates 9 are in contact with the two outer steel bars, the arc-shaped inner wall of the guide sleeve 13 is in contact with the outer top wall of the steel bar. Through the conical surface set on the outer top of the guide sleeve 13, a horn-shaped guide structure that is narrow at the top and wide at the bottom is formed. This allows the guide component 2 to automatically slide and align itself along the conical slope when the precast wall panel is lowered, and smoothly nest with the guide sleeve 13. This makes it easier for the precast wall panel to be fitted onto the embedded steel bars, eliminating the need for workers to repeatedly visually inspect and manually fine-tune, thus greatly reducing the difficulty of alignment. The ball bearings 14 set on the guide sleeve 13 can reduce the wear between the guide component 2 and the guide sleeve 13, making it easier for the guide component 2 and the guide sleeve 13 to cooperate.

[0041] The second drive mechanism includes a third motor 27. The third motor 27 is fixedly installed on the outer wall of the second bracket 26. A second lead screw 28 is rotatably connected to the second bracket 26. One end of the second lead screw 28 extends to the outside of the second bracket 26 and is fixedly connected to the output end of the third motor 27. The second lead screw 28 is symmetrically provided with reverse double threads. The second lead screw 28 is connected to a pair of support arms 30 through a lead screw nut pair. The support arms 30 are fixedly connected to the clamping plate 31. A second limit rod 29 is fixedly connected to the second bracket 26. The support arms 30 and the limit rod 29 are slidably connected. Support plates 32 are fixedly connected to both sides of the bottom end of the clamping plate 31. A support rod 33 is fixedly connected to one of the support plates 32. A groove 34 is opened on the other support plate 32. The groove 34 passes through the clamping plate 31. The support rod 33 is adapted to the groove 34.

[0042] During operation, motor 27 first drives screw 28 to rotate, causing the two support arms 30 and clamping plates 31 to move in opposite directions, increasing the reserved space between the two clamping plates 31 to facilitate the placement of the precast wall panel. During the process of the precast wall panel being lowered by the hoist, the bottom of the precast wall panel first contacts the support rods 33 on the two clamping plates 31. At this time, the hoist stops lowering the wall panel, and motor 27 drives the two support arms 30 to move relative to each other, causing the two clamping plates 31 to bring the support plates 32 closer to each other. The support rods 33 on the two clamping plates 31 insert into the grooves 34 on the support plates 32 of each other until the clamping plates 31 are in contact with the outer wall of the wall panel. Through the cooperation of motor 27, screw 28 and clamping plates 31, the precast wall panel is automatically centered and clamped. The clamping process is stable and symmetrical, without any unilateral deviation, ensuring that the wall panel is always in the center alignment reference, providing a guarantee for the subsequent precise alignment with the embedded steel bars.

[0043] The second guide assembly includes a fixed plate 35 and a second guide sleeve 42. The fixed plate 35 is fixedly connected to the outer wall of the clamping plate 31 on the side away from the support plate 32. The fixed plate 35 is threadedly connected to a second screw 36. One end of the second screw 36 extends between the two support plates 32 and is rotatably connected to a third bracket 38. A pair of second guide rods 37 are slidably connected to the fixed plate 35. Both of the second guide rods 37 are fixedly connected to the third bracket 38. A third lead screw 39 is rotatably connected to the third bracket 38. A slider 41 is connected to the third lead screw 39 through a lead screw nut pair. A pair of third limiting rods 40 are fixedly connected to the third bracket 38. Both of the third limiting rods 40 are slidably connected to the slider 41. A second guide sleeve 42 is fixedly connected to the slider 41. The second guide sleeve 42 is semi-circular in shape. The inner side of the bottom end of the second guide sleeve 42 is tapered. The second guide sleeve 42 is adapted to the first guide sleeve 13.

[0044] A mounting plate 43 is fixedly connected to the top of the inner wall of the guide sleeve 2 42. A toothed rod 1 44 is slidably connected to the center of the mounting plate 43. A spring 45 is fixedly connected between the bottom end of the toothed rod 1 44 and the bottom of the mounting plate 43. Several U-shaped frames 47 are evenly fixedly connected to the top of the mounting plate 43. Several gears 48 are evenly meshed with the outer side of the toothed rod 1 44. A toothed rod 2 46 is meshed with the side of the gear 48 away from the toothed rod 1 44. The toothed rod 2 46 is slidably connected to the mounting plate 43. The gear 48 is rotatably connected to the U-shaped frame 47.

[0045] During operation, after the precast wall panel is clamped by the clamping plate 31, the worker can adjust the position of the guide sleeve 42 by rotating the screw 36 and the lead screw 39 until the toothed rod 46 slides into the reserved hole at the bottom of the precast wall panel, aligning the guide sleeve 42 with the reserved hole at the bottom of the wall panel. During this process, before sliding into the reserved hole, the toothed rod 46 is squeezed by the bottom of the wall panel, causing the gear 48 to rotate, which causes the toothed rod 44 to slide upward and compress the spring 45. After several toothed rods 46 have slid to the reserved hole of the wall panel, the toothed rod 44 slides upward and resets under the elastic force of the spring 45, simultaneously driving the gear 48 to rotate and causing the toothed rod 46 to slide into the reserved hole. The bottom end of the toothed rod 46 impacts the bottom of the mounting plate 43. During the adjustment operation, the worker only needs to hear the impact sound of the toothed rod 46 hitting the mounting plate 43 to confirm that the guide sleeve 42 is in place. Aligned with the pre-drilled holes in the wall panel, without the need to bend over for observation, the guide sleeve 42 is easily adjusted by workers according to the actual position of the pre-drilled holes at the bottom of different wall panels, thanks to the screw 36 on the fixing plate 35, the lead screw 39 on the bracket 38, and the slider 41. This further improves the positioning accuracy. The guide sleeve 42 adopts a semi-circular structure with a conical surface on the inner side of the bottom end, which can form a conical self-centering insertion fit with the guide sleeve 13 at the top of the pre-embedded steel bar. During the lowering of the wall panel, the conical surface guides the alignment and automatically corrects the front-back and left-right deviations, ensuring that the pre-drilled holes and pre-embedded steel bars are precisely matched without the need for repeated manual correction. The guide sleeve 42 can achieve multi-dimensional positional fine adjustment in front-back and left-right directions, and can adapt to pre-drilled holes of different diameters and hole spacings in wall panels. It has strong versatility and can meet the positioning and installation needs of various prefabricated components without changing tooling.

[0046] The hoisting mechanism includes a top plate 16 and a second motor 18. A pair of top plates 16 are fixedly connected to the top of the mounting frame 1. The second motor 18 is fixedly installed on the outer wall of one of the top plates 16. A rotating roller 17 is rotatably connected between the pair of top plates 16. The output end of the second motor 18 is fixedly connected to one end of the rotating roller 17. A traction rope 19 is fixedly connected to the rotating roller 17. The end of the traction rope 19 away from the rotating roller 17 is fixedly connected to the top of the mounting base 20.

[0047] During operation, motor 18 drives the rotating roller 17 to rotate, and the raising and lowering of the traction rope 19 can drive the mounting base 20 to cooperate with the hoist to lower the precast wall panel, thus achieving synchronous lifting.

[0048] The lateral limiting assembly includes a support 21 and an electric push rod 22. The support 21 is fixedly connected to the top of the mounting base 20 near the bracket 26. The electric push rod 22 is fixedly installed on the top of the support 21. The output end of the electric push rod 22 is fixedly connected to a side plate 23. An adjustment hole 24 is provided on the mounting base 20. An adjustment rod 25 is fixedly connected to the bracket 26. The adjustment rod 25 is slidably connected to the adjustment hole 24.

[0049] During operation, as the precast wall panel and mounting base 20 move downwards as a whole, guide sleeve 13 first slides into guide sleeve 2 42. During this process, spring 45 is in its natural state. Because the bottom end of rack 1 44 is lower than the bottom end of rack 2 46, the bottom end of rack 1 44 first contacts the top end of guide sleeve 1 13 and is pushed upwards. Gear 48 then rotates, and rack 2 46 slides down and disengages from the pre-drilled hole in the wall panel. Afterwards, the worker moves side plate 23 using electric push rod 22 to achieve lateral positioning of the precast wall panel. After side plate 23 completes lateral positioning, the worker rotates screw 2 36 to move bracket 3 38 and guide sleeve 2. 42 moves outward as a whole. In addition, motor 15 drives limit plate 19 and guide sleeve 2 42 to move outward as a whole until guide sleeve 13 and guide sleeve 2 42 are both away from the pre-drilled hole of the wall panel. At the same time, guide sleeve 13 disengages from guide sleeve 2 42. Then, the hoist and motor 2 18 start again, driving the precast wall panel and mounting base 20 to move down as a whole until the embedded steel bar is inserted into the pre-drilled hole at the bottom of the precast wall panel. The worker first drives clamp plate 31 and support plate 32 away from the precast wall panel through motor 3 27, and then moves the mounting frame 1 out as a whole. The final installation of the precast wall panel and embedded steel bar is completed by the hoist.
