Description

Technical Field

[0001] This utility model relates to the technical field of fixing brackets for embedded rubber waterstops, and in particular to a fixing bracket for embedded rubber waterstops that is easy to install. Background Technology

[0002] Embedded rubber waterstops are waterproofing materials used in construction engineering, primarily at the joints of concrete structures to prevent water leakage. They are typically made of highly elastic and wear-resistant rubber, possessing excellent sealing and anti-aging properties. In modern construction engineering, the effectiveness of waterproofing measures directly affects the durability and safety of buildings. Due to their superior waterproofing performance, embedded rubber waterstops are widely used in waterproofing projects such as underground structures, tunnels, and water tanks. During installation, they require fixation using supports, thus necessitating a convenient mounting bracket for embedded rubber waterstops.

[0003] Traditional methods of installing embedded rubber waterstops require workers to place the rubber waterstop directly inside the construction steel reinforcement frame, and then fix it through complex steps such as tying the steel reinforcement and welding the formwork. This method is difficult to implement. During the tying and welding process, the rubber waterstop may shift due to improper operation, which will affect its waterproofing effect when the concrete is poured. This method is cumbersome, time-consuming, and labor-intensive, reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a convenient mounting bracket for embedded rubber waterstops.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mounting bracket for an easily installed embedded rubber waterstop includes two connecting seats. Each connecting seat has an installation groove on its inner sidewall, and a clamping plate is provided on the inner sidewall of each installation groove. Each connecting seat has a first moving mechanism on its outer sidewall for moving the clamping plates. Each connecting seat also has a fixing mechanism on its two outer sidewalls for fixing the two connecting seats. Multiple vertical rectangular sleeves are linearly fixed at equal intervals at the bottom of each connecting seat. These vertical rectangular sleeves are arranged in two groups. A rotating shaft is passed through the outer sidewall of each group of vertical rectangular sleeves. A third transmission block is fixed to both ends of each rotating shaft. Horizontal rectangular sleeves are fixed to the outer sidewalls of the multiple vertical rectangular sleeves. Rectangular sliders are slidably connected to the inner sidewalls of the multiple horizontal rectangular sleeves. Two guide rods are symmetrically fixed at one end of each slider. One end of each pair of guide rods passes through the outer wall of one end of a horizontal rectangular sleeve. The same clamping block is fixed at one end of each pair of guide rods. An arc-shaped groove is opened at one end of each of the clamping blocks. A second moving mechanism for moving the rectangular slider is provided inside each of the horizontal rectangular sleeves. During use, the two fixing mechanisms can quickly fix the two connecting seats. Then, with the help of the two first moving mechanisms, the two clamping plates can be moved closer to each other to clamp and fix the embedded rubber waterstop. There is no need for workers to fix it through complicated steps such as tying steel bars and welding formwork. This avoids the positional displacement of the rubber waterstop caused by workers during the tying and welding process, and reduces the construction difficulty.

[0007] Preferably, the fixing mechanism includes a support plate, which is fixed to the outer wall of one end of one of the connecting seats. A second threaded rod is rotatably connected to the inner wall of the support plate. A second transmission block is fixed to one end of the second threaded rod. A second internal threaded sleeve is fitted on the side wall of the second threaded rod, and the second internal threaded sleeve and the second threaded rod are adapted to each other. An annular plate is rotatably fitted on the outer wall of the second internal threaded sleeve. A connecting plate is fixed on the outer wall of the annular plate. A pin is fixed on the inner wall of the connecting plate. A through hole is opened on the outer wall of the other connecting seat, and the pin and the through hole are adapted to each other. By using a hand-held power component in conjunction with two second transmission blocks, the two second threaded rods are driven to rotate. During the rotation of the two second threaded rods, the worker holds the two connecting plates. At this time, the two second internal threaded sleeves move along the two second threaded rods respectively, thereby driving the two second transmission blocks to move until the two pins enter the two through holes respectively, thus completing the fixing of the two connecting seats.

[0008] Preferably, the first moving mechanism includes two sliding rods, which are symmetrically fixed to the outer wall of one of the clamping plates. One end of each sliding rod passes through the outer wall of one of the connecting seats. Two sliding grooves are symmetrically formed on the outer wall of one of the connecting seats, and both sliding grooves communicate with one of the mounting grooves. A connecting rod is provided inside each of the two sliding grooves, and one end of each connecting rod is fixed to one of the clamping plates. A first threaded rod is rotatably connected to the middle of the outer wall of one of the connecting seats. A first internal threaded sleeve is fitted on the side wall of the first threaded rod, and the first internal threaded sleeve and the first threaded rod are adapted to each other. The other ends of both connecting rods are fixed to the first internal threaded sleeve. A first transmission block is fixed to one end of the first threaded rod. The two first threaded rods are rotated by a power component in conjunction with the two first transmission blocks. The rotation of the two first threaded rods, in conjunction with the two first internal threaded sleeves, drives the two connecting rods to move, thereby causing the two clamping plates to move closer to each other and clamp and fix the embedded rubber waterstop. This eliminates the need for workers to perform complex steps such as tying reinforcing bars and welding formwork for fixing, and avoids the situation where the rubber waterstop shifts during the tying and welding process.

[0009] Preferably, the second moving mechanism includes a third threaded rod, which is rotatably connected to the inner wall of one end of one of the horizontal rectangular sleeves, and one end of the third threaded rod passes through the interior of one of the vertical rectangular sleeves. A threaded hole is provided in the middle of the surface of the rectangular slider, and the threaded hole is adapted to the rectangular slider. A second bevel gear is sleeved on one end of the third threaded rod. A first bevel gear is provided inside one of the vertical rectangular sleeves. The first bevel gear is sleeved on the side wall of one of the rotating shafts, and the first bevel gear and the second bevel gear mesh. Two third transmission blocks drive two rotating shafts to rotate, thereby driving multiple first bevel gears to rotate simultaneously. In conjunction with multiple second bevel gears, multiple third threaded rods rotate. The rotation of multiple third threaded rods, in conjunction with multiple threaded holes, causes multiple rectangular sliders to move away from each other in pairs along the inner walls of multiple horizontal rectangular sleeves. During the process of multiple rectangular sliders moving away from each other in pairs, multiple sets of guide rods drive multiple sets of clamping blocks to move away from each other in pairs until the arc grooves on multiple clamping blocks are in contact with the external reinforcing bars, thus completing the entire installation work. The operation is simple, saves time, and improves work efficiency.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, this device, through the design of two fixing mechanisms, can quickly fix the two connecting seats. In conjunction with the two first moving mechanisms, it can drive the two clamping plates to move closer to each other, thereby clamping and fixing the embedded rubber waterstop. This eliminates the need for workers to perform complex steps such as tying steel bars and welding formwork, avoiding the displacement of the rubber waterstop caused by workers during the tying and welding process, and reducing the difficulty of construction.

[0012] 2. By rotating two shafts in conjunction with multiple second moving mechanisms, multiple clamping blocks can be moved away from each other in pairs. When the arc-shaped grooves of multiple clamping blocks are in close contact with the external steel bars, the installation of the bracket can be completed. The operation is simple, saves time, and improves work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 - Figure 7 A mounting bracket for an easily installed embedded rubber waterstop includes two connecting seats 1. Each connecting seat 1 has an installation groove 15 on its inner sidewall, and a clamping plate 17 is provided on the inner sidewall of each of the two installation grooves 15. Each connecting seat 1 has a first moving mechanism on its outer sidewall for moving the clamping plates 17. Each connecting seat 1 also has a fixing mechanism on its outer sidewall at both ends for fixing the two connecting seats 1. Multiple vertical rectangular sleeves 11 are linearly fixed at equal intervals at the bottom of each connecting seat 1. The multiple vertical rectangular sleeves 11 are arranged in two groups. A rotating shaft 13 is passed through the outer sidewall of each group of vertical rectangular sleeves 11. A third transmission block 16 is fixed to both ends of each of the two rotating shafts 13. Horizontal rectangular sleeves 12 are fixed to the outer sidewalls of the multiple vertical rectangular sleeves 11. Rectangular sliders 18 are slidably connected to the inner sidewalls of the multiple horizontal rectangular sleeves 12. Two guide rods 22 are symmetrically fixed to one end of each slider 18. One end of each pair of guide rods 22 passes through the outer wall of one end of a horizontal rectangular sleeve 12. The same clamping block 23 is fixed to one end of each pair of guide rods 22. An arc-shaped groove is opened at one end of each clamping block 23. A second moving mechanism for moving the rectangular slider 18 is set inside each of the multiple horizontal rectangular sleeves 12. In the process of use, the two connecting seats 1 can be quickly fixed by the design of the two fixing mechanisms. Then, with the help of the two first moving mechanisms, the two clamping plates 17 can be moved closer to each other to clamp and fix the embedded rubber waterstop. There is no need for workers to fix it by tying steel bars and welding formwork. This avoids the positional displacement of the rubber waterstop caused by workers during the tying and welding process and reduces the construction difficulty.

[0023] Furthermore, the fixing mechanism includes a support plate 8, which is fixed to the outer wall of one end of one of the connecting seats 1. A second threaded rod 9 is rotatably connected to the inner wall of the support plate 8. A second transmission block 10 is fixed to one end of the second threaded rod 9. A second internal threaded sleeve 24 is sleeved on the side wall of the second threaded rod 9, and the second internal threaded sleeve 24 is adapted to the second threaded rod 9. An annular plate 25 is rotatably sleeved on the outer wall of the second internal threaded sleeve 24. A connecting plate 26 is fixed on the outer wall of the annular plate 25. A pin 27 is fixed on the inner wall of the connecting plate 26. A through hole 28 is opened on the outer wall of the other connecting seat 1, and the pin 27 is adapted to the through hole 28. By using a hand-held power component in conjunction with the two second transmission blocks 10, the two second threaded rods 9 are driven to rotate. During the rotation of the two second threaded rods 9, the worker holds the two connecting plates 26. At this time, the two second internal threaded sleeves 24 move along the two second threaded rods 9 respectively, thereby driving the two second transmission blocks 10 to move until the two pins 27 enter the two through holes 28 respectively, thus completing the fixing of the two connecting seats 1.

[0024] Furthermore, the first moving mechanism includes two slide rods 14, which are symmetrically fixed to the outer wall of one of the clamping plates 17. One end of each slide rod 14 passes through the outer wall of one of the connecting seats 1. Two sliding grooves 3 are symmetrically formed on the outer wall of one of the connecting seats 1, and both sliding grooves 3 communicate with one of the mounting grooves 15. A connecting rod 6 is provided inside each of the two sliding grooves 3, and one end of each connecting rod 6 is fixed to one of the clamping plates 17. A first threaded rod 4 is rotatably connected to the middle of the outer wall of one of the connecting seats 1. A first internal threaded sleeve 5 is sleeved on the side wall of the first threaded rod 4. The first threaded rod 4 is adapted to the first threaded rod 5. The other ends of the two connecting rods 6 are fixed to the first internal threaded sleeve 5. The first threaded rod 4 is fixed with a first transmission block 7 at one end. The two first threaded rods 4 are rotated by the power component in cooperation with the two first transmission blocks 7. The rotation of the two first threaded rods 4 in cooperation with the two first internal threaded sleeves 5 drives the two connecting rods 6 to move, thereby driving the two clamping plates 17 to move closer to each other and clamp and fix the embedded rubber waterstop. There is no need for workers to fix it by tying steel bars and welding formwork, which avoids the situation where the rubber waterstop is displaced during the tying and welding process.

[0025] Furthermore, the second moving mechanism includes a third threaded rod 19, which is rotatably connected to the inner wall of one end of a horizontal rectangular sleeve 12, and one end of the third threaded rod 19 penetrates the interior of one vertical rectangular sleeve 11. A threaded hole is provided in the middle of the surface of the rectangular slider 18, and the threaded hole is adapted to the rectangular slider 18. A second bevel gear 21 is sleeved on one end of the third threaded rod 19. A first bevel gear 20 is provided inside one of the vertical rectangular sleeves 11. The first bevel gear 20 is sleeved on the side wall of one of the rotating shafts 13, and the first bevel gear 20 and the second bevel gear 21 mesh. Through the two of the second bevel gears... The three transmission blocks 16 drive the two rotating shafts 13 to rotate, which in turn drives multiple first bevel gears 20 to rotate simultaneously. These, in conjunction with multiple second bevel gears 21, drive multiple third threaded rods 19 to rotate. The rotation of the multiple third threaded rods 19, in conjunction with multiple threaded holes, causes multiple rectangular sliders 18 to move away from each other in pairs along the inner walls of multiple horizontal rectangular sleeves 12. As the multiple rectangular sliders 18 move away from each other in pairs, multiple sets of guide rods 22 drive multiple sets of clamping blocks 23 to move away from each other in pairs until the arc grooves on the multiple clamping blocks 23 are all in contact with the external reinforcing bars. This completes the entire installation work. The operation is simple, saves time, and improves work efficiency.

[0026] Working Principle: During use, the embedded rubber waterstop is placed between the two connecting seats 1. A handheld power unit, in conjunction with two second transmission blocks 10, drives the two second threaded rods 9 to rotate. While the two threaded rods 9 rotate, the worker holds the two connecting plates 26. At this time, the two second internal threaded sleeves 24 move along the two threaded rods 9, thereby moving the two second transmission blocks 10 until the two pins 27 enter the two through holes 28, thus fixing the two connecting seats 1. After fixing, the power unit, in conjunction with two first transmission blocks 7, drives the two first threaded rods 4 to rotate. The rotation of the two first threaded rods 4, in conjunction with the two first internal threaded sleeves 5, drives the two connecting rods 6 to move, thereby bringing the two clamping plates 17 closer together to clamp and fix the embedded rubber waterstop. This eliminates the need for the worker to tie the waterstop. The installation process involves complex steps such as tying reinforcing bars and welding formwork to secure the rubber waterstop, preventing positional displacement of the rubber waterstop during the tying and welding process. After securing, two third transmission blocks 16 drive two rotating shafts 13 to rotate, which in turn drives multiple first bevel gears 20 to rotate simultaneously. These, in conjunction with multiple second bevel gears 21, drive multiple third threaded rods 19 to rotate. The rotation of the multiple third threaded rods 19, combined with multiple threaded holes, causes multiple rectangular sliders 18 to move away from each other along the inner walls of multiple horizontal rectangular sleeves 12. As the multiple rectangular sliders 18 move away from each other, multiple sets of guide rods 22 drive multiple sets of clamping blocks 23 to move away from each other until the arc grooves on the multiple clamping blocks 23 are in contact with the external reinforcing bars, thus completing the entire installation work. This method is simple to operate, saves time, and improves work efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
