Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a precast component repair and support device. Background Technology

[0002] With the rapid development of the construction industry and technological progress, precast components are widely used in modern construction projects due to their high efficiency and environmental protection characteristics. However, in the actual production and use process, precast components may sometimes develop micro-cracks or other damage, requiring timely repair. Therefore, a precast component repair and support device is needed.

[0003] When repairing precast components, the traditional approach is to use ordinary wooden supports or steel pipe scaffolding to build temporary support platforms. Although this method is simple and easy to implement, it has poor stability and safety, and is prone to safety accidents. Existing technology uses customized steel structure platforms, which are more stable and reliable, but the cost is higher and they are not convenient for transportation and storage. However, in actual use, customized steel structure platforms are welded as a whole and cannot be adjusted according to the shape of the repaired parts, and are also inconvenient for transportation and storage, which reduces the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prefabricated component repair support device, which aims to improve the practicality of the existing customized steel structure frame in actual use. Because it is integrally welded, it cannot be adjusted according to the shape of the repaired part, and it is inconvenient to transport and store, which reduces the practicality of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precast component repair support device, comprising two crossbeams, with multiple A-frames arranged on the left and right sides of the bottom of the two crossbeams, an adjustment mechanism arranged on the inner wall of each of the multiple A-frames, a reinforcing rod arranged between adjacent A-frames, a connecting plate I fixedly connected to the left and right ends of each of the multiple reinforcing rods, bolts I threadedly connected to the front and rear sides of the outer wall of each of the multiple connecting plates I, and the multiple connecting plates I threadedly connected to the A-frames through the bolts I, a connecting plate II fixedly connected to the top of each of the multiple reinforcing rods, bolts II threadedly connected to the front and rear sides of the top of each of the multiple connecting plates II, and the multiple connecting plates II threadedly connected to the crossbeams through the bolts II, and multiple threaded holes opened on the upper and lower sides of adjacent ends of each of the multiple A-frames.

[0006] Through the above technical solution: the two crossbeams serve as the main load-bearing components, and the multiple A-frames at their bottom provide stable support, enabling the crossbeams to be placed firmly on the ground. This distributes the weight and pressure of the prefabricated components evenly to the ground. The connecting plates at the left and right ends of the reinforcing rod are threadedly connected to the A-frames by bolts, allowing the reinforcing rod to tightly connect adjacent A-frames together, preventing the crossbeams from shifting relative to the A-frames and facilitating disassembly. Multiple threaded holes are adapted to bolts, and by installing bolts in threaded holes at different heights, the height of the crossbeams can be adjusted to accommodate repair parts of different shapes.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes sliding columns, which are slidably connected to the upper and lower sides of the inner wall of the A-frame. Each of the sliding columns has a mounting plate fixedly connected to its top. Each of the mounting plates has three bolts threaded around its top. Each of the mounting plates is threaded to the crossbeam via the three bolts. Each of the sliding columns has a threaded rod fixedly connected to its bottom end. Each of the threaded rods has a support seat threaded to its outer bottom wall.

[0009] The above technical solution works as follows: When the height of the crossbeam needs to be adjusted, the bolts are unscrewed, and then the crossbeam is lifted and moved upward. During the upward movement of the crossbeam, the mounting plate will move upward, which in turn will move the sliding column and the threaded rod upward. When the crossbeam moves to the appropriate height, the support seat is rotated. Since the support seat is threadedly connected to the threaded rod, it will move downward during the rotation of the support seat until it hits the bottom of the inner wall of the A-frame, thereby providing support for the sliding column and preventing the sliding column from moving downward, thus adjusting the height of the crossbeam.

[0010] As a further description of the above technical solution:

[0011] Each of the A-frames has rotatably connected casters around its bottom perimeter, and each of the casters has a locking plate rotatably connected to its inner wall.

[0012] The above technical solution allows the movable wheel to turn the device in a confined space. After the device is positioned, the locking plate can lock the movable wheel to prevent the device from moving.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the crossbeam is provided with multiple reinforcing ribs 1 on both the upper and lower sides, and multiple reinforcing ribs 2 are fixedly connected to each other of the multiple reinforcing ribs 1.

[0015] Through the above technical solution, stiffener 2 and stiffener 1 together construct a crisscrossing reinforcement network. When the beam is under stress, stiffener 2 can distribute the stress in all directions to the entire reinforcement network, so that the stress will not be concentrated in a specific area, thereby further enhancing the overall structural stability of the beam.

[0016] As a further description of the above technical solution:

[0017] The left and right ends of the crossbeam are fixedly connected to fixing blocks, and the inner walls of the two fixing blocks are rotatably connected to lifting rings.

[0018] The above technical solution allows for the following: when the beam needs to be lifted and its height adjusted, the hoisting rope is attached to the lifting ring to facilitate lifting the beam.

[0019] As a further description of the above technical solution:

[0020] The top of the outer wall of the crossbeam is provided with multiple scale grooves, which are arranged equidistantly on the left and right sides of the top of the crossbeam.

[0021] With the above technical solution, when supporting and repairing precast components, workers can accurately determine the placement position of the precast components on the crossbeam according to the scale groove.

[0022] As a further description of the above technical solution:

[0023] Multiple rotating handles are fixedly connected to the outer walls of the multiple support bases, and multiple anti-slip blocks are fixedly connected to the outer walls of the multiple rotating handles.

[0024] The above technical solution provides a force point for the rotating support base, making it easier to rotate the support base. The anti-slip block increases the friction between the hand and the rotating handle, preventing the hand from slipping when holding the rotating handle.

[0025] As a further description of the above technical solution:

[0026] Sliding strips are fixedly connected to the left and right sides of the outer walls of the multiple sliding columns, and sliding grooves are opened on the left and right sides of the inner walls of the multiple A-shaped frames. The multiple sliding strips are slidably connected to the corresponding sliding grooves.

[0027] The above technical solution provides a sliding track for the sliding bar, preventing the sliding column from shifting during the sliding process.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, multiple A-frames provide support for the crossbeam, evenly transmitting the pressure on the crossbeam to the ground. At the same time, the reinforcing rod connects the crossbeam, A-frames, and reinforcing rod into a whole, improving the stability of the device. By using bolt one and bolt two to connect and fix the crossbeam, A-frames, and reinforcing rod, it is easy to disassemble and transport them, solving the problem of inconvenient transportation and storage, and improving the convenience of the device.

[0030] 2. In this utility model, when adjusting the height of the crossbeam, the sliding column moves upward along with the crossbeam, driving the threaded rod and its rotating seat to move upward together. By rotating the rotating seat, the rotating seat can move downward along the threaded rod. When the rotating seat moves to the extrusion A-frame, since its inner wall top is threadedly connected to the threaded rod, it can provide strong support for the threaded rod and the sliding column, improving the stability of the device and enabling the device to adapt to repair parts of different shapes.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a precast component repair support device, comprising two crossbeams 1. The crossbeams 1 serve as the main transverse structural components of the entire support device, playing a crucial role in bearing the weight of the precast components. Multiple A-frames 3 are provided on the left and right sides of the bottom of each of the two crossbeams 1. The A-frames 3 can stably support the crossbeams 1. Adjustment mechanisms 2 are provided on the inner walls of each of the multiple A-frames 3, allowing adjustment of the height of the crossbeams 1. Reinforcing rods 4 are provided between adjacent A-frames 3, enhancing the overall structural integrity and stability of the support device and preventing deformation or displacement of any single A-frame 3 due to excessive stress. Connecting plates 5 are fixedly connected to the left and right ends of each reinforcing rod 4. Bolts 6 are threadedly connected to the front and rear sides of the outer walls of each connecting plate 5. Each connecting plate 5 is threadedly connected to the A-frames 3 via bolts 6. The reinforcing rods 4 can be firmly fixed between adjacent A-frames 3. The A-frames 3 are tightly connected to form a whole structure. The top of each of the multiple reinforcing rods 4 is fixedly connected to a connecting plate 2 7. The top front and rear sides of the multiple connecting plates 2 7 are threaded with bolts 2 8. The multiple connecting plates 2 7 are threaded to the crossbeam 1 through bolts 2 8, which tightly connects the crossbeam 1, reinforcing rods 4 and A-frames 3 together. The upper and lower sides of the adjacent ends of the multiple A-frames 3 are provided with multiple threaded holes 9. The threaded holes 9 are adapted to bolts 2 8. When adjusting the height of the crossbeam 1, bolts 2 8 can be threaded to different threaded holes 9. The bottom of the multiple A-frames 3 is rotatably connected to the moving wheels 10. In actual use, the workers can easily push the support device to move on the ground through the moving wheels 10. The inner wall of the multiple moving wheels 10 is rotatably connected to a locking plate 11. When the support device moves to the predetermined precast component support position, the locking plate 11 can be operated to lock the moving wheels 10.

[0042] Specifically, the two crossbeams 1 serve as the main load-bearing components, and the multiple A-frames 3 at their bottom provide stable support, enabling the crossbeams 1 to be placed firmly on the ground and distributing the weight and pressure of the prefabricated components evenly to the ground. The connecting plates 5 at the left and right ends of the reinforcing rods 4 are threadedly connected to the A-frames 3 by bolts 6, so that the reinforcing rods 4 can tightly connect adjacent A-frames 3 together, preventing the crossbeams 1 from shifting relative to the A-frames 3 and facilitating disassembly. Multiple threaded holes 9 are adapted to bolts 6. By installing bolts 6 in threaded holes 9 at different heights, the height of the crossbeams 1 can be adjusted to accommodate repair parts of different shapes. The moving wheels 10 allow the device to turn in a confined space. After the device is positioned, the locking plate 11 can lock the moving wheels 10 to prevent the device from moving.

[0043] Reference Figure 1 , Figure 3 and Figure 7The adjustment mechanism 2 includes sliding columns 201, which are slidably connected to the upper and lower sides of the inner wall of the A-frame 3. The sliding columns 201 can slide freely up and down inside the A-frame 3, providing a basic structure for the entire adjustment mechanism 2 to adjust the height of the crossbeam 1. Mounting plates 202 are fixedly connected to the tops of multiple sliding columns 201. The mounting plates 202 mainly serve as a bridge connecting the sliding columns 201 and the crossbeam 1. Bolts 203 are threaded around the top of multiple mounting plates 202, connecting the mounting plates 202 and the crossbeam 1. This facilitates disassembly when not in use and makes transportation easier. Multiple mounting plates 202 are threaded to the crossbeam 1 via bolts 203. Threaded rods 204 are fixedly connected to the bottom ends of multiple sliding columns 201, providing connections for other components. Support seats 205 are threaded to the bottom of the outer walls of multiple threaded rods 204. When the threaded rods 204 move to… At a suitable height, rotating the support base 205 causes it to move downwards along the threaded rod 204. When the bottom end of the support base 205 contacts the A-frame 3, it provides stable support for the threaded rod 204, preventing the threaded rod 204 and the sliding column 201 from moving downwards. Multiple rotating handles 17 are fixedly connected to the outer walls of the multiple support bases 205, and multiple anti-slip blocks 18 are fixedly connected to the outer walls of the multiple rotating handles 17. Sliding strips 19 are fixedly connected to the left and right sides of the outer walls of the multiple sliding columns 201, and sliding grooves 20 are opened on the left and right sides of the inner walls of the multiple A-frames 3. The multiple sliding strips 19 are slidably connected to the corresponding sliding grooves 20. The rotating handles 17 provide a force point for rotating the support base 205, making it easier to rotate the support base 205. The anti-slip blocks 18 increase the friction between the hand and the rotating handles 17, preventing the hand from slipping when holding the rotating handles 17. The sliding grooves 20 provide a sliding track for the sliding strips 19, preventing the sliding columns 201 from shifting during sliding.

[0044] Specifically, when the height of the crossbeam 1 needs to be adjusted, bolt 6 is unscrewed, and then the crossbeam 1 is lifted and moved upward. During the upward movement of the crossbeam 1, the mounting plate 202 will move upward, thereby causing the sliding column 201 and the threaded rod 204 to move upward. After the crossbeam 1 moves to the appropriate height, the support seat 205 is rotated. Since the support seat 205 is threadedly connected to the threaded rod 204, it will move downward during the rotation of the support seat 205 until it hits the bottom of the inner wall of the A-frame 3, thereby providing support for the sliding column 201 and preventing the sliding column 201 from moving downward, thus adjusting the height of the crossbeam 1. The rotating handle 17 provides a force point for rotating the support seat 205, making it easy to rotate the support seat 205. The anti-slip block 18 increases the friction between the hand and the rotating handle 17, preventing the hand from slipping when holding the rotating handle 17. The sliding groove 20 provides a sliding track for the sliding bar 19, preventing the sliding column 201 from deviating during the sliding process.

[0045] Reference Figure 1, Figure 5 and Figure 6 Multiple reinforcing ribs 12 are provided on both the upper and lower sides of the inner wall of the beam 1. When the beam 1 bears the weight of the precast component, the reinforcing ribs 12 can share part of the stress. Multiple reinforcing ribs 12 are fixedly connected to each other, and the reinforcing ribs 13 and the reinforcing ribs 12 together form a crisscrossing reinforcement network. When the beam 1 is under stress, the reinforcing ribs 13 can distribute the stress in all directions to the entire reinforcement network, so that the stress does not concentrate in a specific area, thereby further enhancing the overall structural stability of the beam 1. The left and right ends of the crossbeam 1 are fixedly connected to fixed blocks 14, which provide the installation foundation and connection position for the lifting rings 15. The inner walls of the two fixed blocks 14 are rotatably connected to the lifting rings 15, and the hoisting ropes are hung on the lifting rings 15 for easy hoisting operation. The top of the outer wall of the crossbeam 1 is provided with multiple scale grooves 16, which are equidistantly arranged on the top left and right sides of the crossbeam 1. When supporting and repairing the precast components, the scale grooves 16 have the function of auxiliary positioning and measurement, and can accurately determine the placement position of the precast components on the crossbeam 1 according to the scale grooves 16.

[0046] Specifically, the main function of stiffener 12 is to improve the bending resistance and load-bearing capacity of the crossbeam 1 itself. Stiffener 13 can enhance the integrity of the internal structure of the entire crossbeam 1, connect all stiffeners 12 together, so that they can work together to bear the force, more effectively disperse the stress, and further improve the load-bearing capacity of the crossbeam 1. Fixing block 14 provides an installation base for lifting ring 15. When it is necessary to lift the crossbeam 1 to adjust the height, the hoisting rope is hung on the lifting ring 15 to facilitate the lifting of the crossbeam 1. When supporting and repairing precast components, workers can accurately determine the placement position of the precast components on the crossbeam 1 according to the scale groove 16 to ensure that the precast components can be accurately located in the appropriate support area of ​​the support device.

[0047] Working principle: Two crossbeams 1 serve as the main load-bearing components, providing support for the repaired parts. Multiple A-frames 3 provide stable support for the crossbeams 1, ensuring they are firmly placed on the ground. This evenly distributes the weight and pressure of the repaired parts onto the ground. The connecting plates 5 at the left and right ends of the reinforcing rod 4 are threadedly connected to the A-frames 3 via bolts 6, allowing the reinforcing rod 4 to tightly connect adjacent A-frames 3 together, preventing displacement of the crossbeams 1 relative to the A-frames 3 and facilitating disassembly. Multiple threaded holes 9 are adapted to bolts 6; by installing bolts 6 into threaded holes 9 at different heights, adjustment is possible. The height of the crossbeam 1 can be adjusted to accommodate repair parts of different shapes. When the height of the crossbeam 1 needs to be adjusted, bolt 6 is unscrewed, and then the crossbeam 1 is lifted and moved upward. During the upward movement of the crossbeam 1, the mounting plate 202 will move upward, thereby moving the sliding column 201 and the threaded rod 204 upward. When the crossbeam 1 moves to the appropriate height, the support seat 205 is rotated. Since the support seat 205 is threadedly connected to the threaded rod 204, it will move downward during the rotation of the support seat 205 until it hits the bottom of the inner wall of the A-frame 3, thereby providing support for the sliding column 201 and preventing the sliding column 201 from moving downward.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
