Description
Technical Field
[0001] This utility model relates to the field of waterstop clamps, and in particular to a steel edge waterstop clamp for a low side wall. Background Technology
[0002] Waterstops are used for waterproofing during tunnel construction. The linear positioning of the waterstop and the protective layer of the reinforcing steel is very important for the installation of the invert reinforcement. Currently, traditional devices use multiple clamps to clamp the waterstop in order to fix it.
[0003] Related technology can be found in Chinese Patent No. CN220302151U, which discloses a waterstop clamp for building construction. The clamp includes an installation cylinder fixed to the upper end of a casting template. A hollow insert rod is inserted inside the installation cylinder, and a movable rod is inserted inside the insert rod. A push block is provided at the lower end of the movable rod. Several cross-shaped through slots are formed inside the installation cylinder near the push block, evenly distributed along the circumference of the insert rod. A retaining block is inserted inside each through slot, sliding within the cross-shaped through slots on the surface of the installation cylinder and abutting against the inner wall of the installation cylinder. This application's use of retaining blocks achieves fixed installation of the clamp insert rod and the positioning cylinder, reducing the possibility of the clamp insert rod wobbling inside the positioning cylinder and reducing the possibility of waterstop displacement due to insert rod position deviation. This improves the stability of the connection between the clamp insert rod and the positioning cylinder, thereby enhancing the waterstop's fixing effect.
[0004] Regarding the aforementioned technologies, during implementation, it is necessary to adjust the waterstop to make it parallel to the inner wall of the tunnel and placed in a straight line. The operator tightens the bolts and pushes the support rod to slide along the sleeve, so that the support rod drives the waterstop to move and adjust its horizontal position. The support rod is moved manually, and the distance and position of movement rely solely on the operator's experience to judge, or additional measuring tools are needed for precise displacement, which is inconvenient in actual operation. Utility Model Content
[0005] To improve the working efficiency of the device, this application provides a clamp for a steel edge waterstop for a low side wall.
[0006] This application provides a clamp for a steel edge waterstop strip on a low-profile wall, employing the following technical solution:
[0007] A clamp for a steel edge waterstop on a low-profile wall includes a support with several horizontally distributed bolts threaded onto it. A connecting plate is provided on one side of the support, and the connecting plate has adjustment holes along its length. All bolts pass through the adjustment holes and are threaded with nuts. A snap-fit plate is fixedly connected to the side of the connecting plate away from the support, and the snap-fit plate has snap-fit grooves for fixing the waterstop. A movable plate is slidably connected to the support along its transverse direction, and the movable plate moves in a direction parallel to the length direction of the connecting plate. A slot is provided on the movable plate, and a snap-fit block corresponding to the slot is fixedly connected to the connecting plate. When the bolts pass through the adjustment holes and position the connecting plate, the snap-fit block is located on the inner wall of the slot and fits against the inner wall of the slot. A rack is fixedly connected to the upper end of the movable plate, and a gear meshing with the rack is rotatably connected to the support. The support is also provided with a handle for driving the gear to rotate.
[0008] By adopting the above technical solution, the support is used to connect with the casting mold at the construction site. During use, multiple clamps are arranged along the length of the waterstop. Supported by the support, a bolt passes through the support and adjustment hole, then engages with a nut to fix the connecting plate, thereby fixing the clamping plate. The waterstop is located within the clamping groove. The clamping plate fixes and limits the waterstop through the clamping groove, ultimately fixing the waterstop's position. When the clamping plate position needs adjustment, the nut is loosened. When the bolt is loosened from the nut, rotating the handle drives the gear to rotate. The gear meshes with the rack, causing the moving plate to move laterally. The clamping groove guides and limits the protrusion, causing the moving plate to slide laterally along the support. Simultaneously, the connecting plate moves the clamping plate, ultimately causing the clamping plate to move the waterstop horizontally. Adjusting the waterstop position via the clamping plate provides high precision and improves the ease of operation of the device.
[0009] Optionally, the snap-fit plate is rotatably connected to a threaded rod in the transverse direction, and the snap-fit plate is fixedly connected to a limit rod. The limit rod is set parallel to the threaded rod. The inner wall of the snap-fit groove is provided with a sliding plate. The threaded rod passes through the sliding plate and is threadedly connected to the sliding plate. The limit rod passes through the sliding plate and is slidably connected to the sliding plate.
[0010] By adopting the above technical solution, under the limiting action of the limiting rod, the sliding plate gradually approaches and contacts the waterstop by rotating the threaded rod, and then pushes the waterstop to abut against the inner wall of the snap-fit groove. The waterstop and the inner wall of the snap-fit groove cooperate to fix the waterstop, which helps to improve the stability of the waterstop during pouring.
[0011] Optionally, a detection block is fixed at one end of the connecting plate near the support, and a laser emitter is provided on the side of the connecting plate away from the detection block. When the laser emitter is working, it emits visible light. For two adjacent connecting plates, when the laser emitted by the laser emitter on either connecting plate illuminates the detection block of the other connecting plate, the two connecting plates are parallel to each other and are in the same straight line.
[0012] By adopting the above technical solution, the laser emitter will emit visible light when it is working. If the visible light shines on the detection block, the two adjacent connecting plates will be on the same straight line, and the two adjacent snap-fit plates will be on the same straight line. At this time, the waterstop between the two adjacent connecting plates will be in a straight line, which is beneficial to improving the positioning accuracy of the waterstop.
[0013] Optionally, the connecting plate is fixed with a limiting box, the upper end of which has a through hole along the vertical direction, and the laser emitter is provided with a protrusion corresponding to the through hole. The protrusion has a polygonal cross-section and fits against the inner wall of the through hole when inserted into it.
[0014] By adopting the above technical solution, when the protrusion is inserted into the through hole and fits against the inner wall of the through hole, the protrusion and the limiting box cooperate to limit the lateral displacement of the laser emitter, thereby improving the positioning accuracy of the laser emitter. At the same time, it is convenient to replace the laser emitter and helps to improve the stability of the laser emitter during operation.
[0015] Optionally, the connecting plate is provided with a protective tube, and the protective tube is provided with a bolt 2. The bolt 2 passes through the protective tube and is threadedly connected to the connecting plate. The laser emitter is located inside the protective tube. Several flexible pressure blocks are fixedly connected to the inner wall of the protective tube. The flexible pressure blocks abut against the outer surface of the laser emitter and push the laser emitter to fit against the limiting box.
[0016] By adopting the above technical solution, the protective pipe is detachably connected to the connecting plate by bolt two. When the protective pipe is sleeved on the outside of the laser emitter, it protects the laser emitter and reduces the impact of concrete and dust on the laser emitter. The flexible pressure block limits the vertical displacement of the laser emitter, which helps to improve the stability of the laser emitter.
[0017] Optionally, a transparent end cap is fixedly connected to the end of the protective tube away from the detection block, the laser emitted by the laser emitter passes through the transparent end cap, and a protective cover for sealing the transparent end cap is hinged to the end of the protective tube away from the detection block.
[0018] By adopting the above technical solution, when the laser emitter is working, the transparent end cap seals the protective tube without affecting the laser from the laser emitter irradiating the detection block. When the laser emitter is not working, the protective cover protects the transparent end cap, which helps to reduce the probability that the working state of the laser emitter is affected by concrete and dust.
[0019] Optionally, the protective tube is slidably connected with a horizontal plate along the vertical direction. The horizontal plate is located between the transparent end cap and the protective cover. A cleaning brush is fixedly connected to one end of the horizontal plate near the transparent end cap. One end of the horizontal plate passes through the protective tube and extends outside the protective tube. The protective tube has a vertical groove for the horizontal plate to move.
[0020] By adopting the above technical solution, the horizontal bar is pushed vertically, causing it to slide along the length of the vertical groove, which drives the cleaning brush to move and clean the transparent end cap. This helps to reduce the probability that dust and concrete will block the laser and affect the laser detection effect.
[0021] Optionally, the support is provided with a plurality of positioning holes along the vertical direction. The positioning holes are adapted to bolts, and bolts fit into the positioning holes when they pass through them.
[0022] By adopting the above technical solution, the connecting plate has different heights when the bolt is matched with different positioning holes, thus making it suitable for different working environments and improving the convenience of the device's operation.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The support is used to connect with the casting mold at the construction site. During use, multiple clamps are arranged along the length of the waterstop. Supported by the support, a bolt passes through the support and adjustment hole, then engages with a nut to fix the connecting plate, thereby fixing the clamping plate. The waterstop is located within the clamping groove. The clamping plate fixes and limits the waterstop through the clamping groove, ultimately fixing the waterstop's position. When the clamping plate position needs adjustment, the nut is loosened. When the bolt is loosened from the nut, rotating the handle drives the gear to rotate. The gear meshes with the rack, causing the moving plate to move laterally. The clamping groove guides and limits the protrusion, causing the moving plate to slide laterally along the support. Simultaneously, the connecting plate moves the clamping plate, ultimately causing the clamping plate to move the waterstop horizontally. Adjusting the waterstop position via the clamping plate provides high precision and improves the ease of operation of the device.
[0025] 2. Under the limiting action of the limiting rod, the sliding plate gradually approaches and contacts the waterstop by rotating the threaded rod. Then, the waterstop is pushed to abut against the inner wall of the snap-fit groove. The waterstop and the inner wall of the snap-fit groove cooperate to fix the waterstop, which helps to improve the stability of the waterstop during pouring.
[0026] 3. When the laser emitter is working, it emits visible light. If the visible light shines on the detection block, then the two adjacent connecting plates are on the same straight line, and the two adjacent snap-fit plates are on the same straight line. At this time, the waterstop between the two adjacent connecting plates is in a straight line, which helps to improve the positioning accuracy of the waterstop. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.
[0033] This application discloses a clamp for a steel edge waterstop for a low-profile wall. Example
[0034] Reference Figure 1 A clamp for a steel edge waterstop strip on a low side wall includes a support 1. The support 1 has multiple positioning holes 11, which are distributed vertically. Multiple bolts 12 are threaded into the positioning holes 11. All bolts 12 are threaded into the support 1 horizontally. All bolts 12 are threaded into nuts 13 through the support 1. A connecting plate 3 is provided between the bolts 12 and the nuts 13. The connecting plate 3 has adjustment holes 34 for accommodating the bolts 12. The adjustment holes 34 are set along the length of the connecting plate 3. The bolts 12 and the nuts 13 cooperate to fix the connecting plate 3.
[0035] Reference Figure 1 A snap-fit plate 5 is fixedly connected to the side of the connecting plate 3 away from the support 1. When the connecting plate 3 moves, it drives the snap-fit plate 5 to move. The snap-fit plate 5 has a snap-fit groove 51 for accommodating the waterstop. The snap-fit groove 51 guides and limits the horizontal displacement of the waterstop.
[0036] Reference Figure 1A threaded rod 52 is rotatably connected to the snap-fit plate 5. The threaded rod 52 is set parallel to the connecting plate 3. A limit rod 53 is fixedly connected to the snap-fit plate 5. The limit rod 53 is set parallel to the threaded rod 52. A sliding plate 54 is provided on the snap-fit plate 5. The sliding plate 54 is set parallel to the inner wall of the snap-fit groove 51. The limit rod 53 and the threaded rod 52 pass through the sliding plate 54. The threaded rod 52 is threadedly connected to the sliding plate 54. Under the limiting action of the limit rod 53, the threaded rod 52 is rotated, so that the sliding plate 54 moves closer to the waterstop along the length direction of the limit rod 53. The sliding plate 54 pushes the waterstop to abut against the inner wall of the snap-fit groove 51. The sliding plate 54 and the inner wall of the snap-fit groove 51 cooperate to achieve the clamping and fixing of the waterstop.
[0037] Reference Figure 1 and Figure 2 A movable plate 2 is slidably connected to the support 1 in the transverse direction. The movable plate 2 is set parallel to the connecting plate 3. A slot 21 is opened on the movable plate 2 in the vertical direction. A locking block 31 adapted to the slot 21 is fixedly installed on the connecting plate 3. The locking block 31 is inserted into the slot 21 and fits against the inner wall of the slot 21. The slot 21 guides and limits the locking block 31, so that when the movable plate 2 moves, it drives the connecting plate 3 to move in the transverse direction. The length of the locking block 31 is greater than the length of the slot 21. When the bolt 12 is engaged with the positioning hole 11 at different positions, at least part of the locking block 31 is always located in the slot 21.
[0038] Reference Figure 1 and Figure 2 A rack 22 is fixedly mounted on the movable plate 2, and a gear 23 is rotatably connected to the support 1. The gear 23 meshes with the rack 22. When the gear 23 is rotated, it pushes the rack to move along its length. A handle 24 is fixedly connected to the side of the gear 23 away from the locking plate 5. When the handle 24 is rotated, the gear 23 pushes the rack 22 to move, and the rack 22 drives the movable plate 2 to move laterally. The movable plate 2 drives the connecting plate 3 to slide laterally along the support 1, which in turn drives the locking plate 5 to move laterally. Ultimately, the locking plate 5 drives the waterstop to move, thereby adjusting the position of the waterstop in the horizontal direction. The movement accuracy is high, which is beneficial to improving the movement accuracy of the waterstop.
[0039] Reference Figure 3 and Figure 4 Connecting plate 3 (refer to) Figure 1 ) Keep away from the card plate 5 (refer to) Figure 1 A detection block 32 (refer to) is fixedly installed on one side of one end of the device. Figure 2 ), connecting plate 3 (refer to) Figure 1 Deviation detection block 32 (refer to) Figure 2A limiting box 33 is fixedly installed on one side of the laser emitter 4. A through hole 331 is opened on the lower end face of the limiting box 33, and the through hole 331 is set vertically. A laser emitter 4 is inserted into the limiting box 33. A protrusion 41 is fixed on the side of the laser emitter 4 near the limiting box 33. The protrusion 41 has a polygonal cross-section and is inserted into the limiting box 33. The limiting box 33 limits the horizontal displacement of the laser emitter 4 through the protrusion 41.
[0040] Reference Figure 3 and Figure 4 The laser emitter 4 is provided with a protective tube 42 on the outside. One end of the protective tube 42 along the length direction is fixedly connected to a mounting plate. The mounting plate is provided with multiple bolts 421. The protective tube 42 is detachably connected to the support 1 through the bolts 421. A flexible pressure block 422 is provided on the side of the protective tube 42 near the limit box 33. The flexible pressure block 422 can be made of rubber. When the protective tube 42 is sleeved on the outside of the laser emitter 4, the flexible pressure block 422 contacts the laser emitter 4 and applies downward pressure to the laser emitter 4, thereby fixing the laser emitter 4 vertically.
[0041] Reference Figure 3 and Figure 4 The laser emitter 4 is equipped with a switch, and the protective tube has a rectangular block 429 facing the switch. The protective tube 42 has a rectangular hole 428 to avoid the rectangular block 429, so that the operator can trigger the switch by pressing the rectangular block 429 from outside the protective tube 42, thereby starting the laser emitter 4. The rectangular block 429 is equipped with an elastic element, which can be a spring. One end of the spring is connected to the protective tube 42, and the other end is fixedly connected to the upper end of the rectangular block 429. In its natural state, the spring has the tendency to push the rectangular block 429 away from the switch, reducing the probability of accidental activation of the switch when the laser emitter 4 is working, and improving the convenience of the device.
[0042] Reference Figure 3 and Figure 4 A transparent end cap 423 is fixed to the end of the protective tube 42 furthest from the detection block 32. The transparent end cap 423 seals and protects the protective tube 42, preventing damage to the laser emitter 4 from concrete and dust without affecting the laser emitted by the laser emitter 4 from irradiating the detection block 32. A protective cover 424 is hinged to the protective tube 42 at the end furthest from the detection block 32. When the laser emitter 4 is not in use, the protective cover 424 is lowered to protect the laser emitter 4 and the transparent end cap 423, preventing concrete and dust from affecting the device and improving the stability of the laser emitter 4.
[0043] Reference Figure 3 and Figure 4A horizontal plate 425 is provided between the transparent end cap 423 and the protective cover 424. The protective tube 42 has a vertical groove 427 that avoids the horizontal plate 425. The horizontal plate 425 is slidably connected to the protective tube 42 along the length of the vertical groove 427. A cleaning brush 426 is fixedly installed at the end of the horizontal plate 425 away from the protective cover 424. The operator cleans the transparent end cap 423 by moving the cleaning brush 426 up and down to avoid dust affecting the clarity of the laser emitter 4.
[0044] The implementation principle of the steel edge waterstop clamp for a low-profile wall according to this application embodiment is as follows: The waterstop is placed in the clamping groove 51. The threaded rod 52 is rotated, causing the sliding plate 54 to abut against the waterstop. The sliding plate 54 cooperates with the inner wall of the clamping groove 51 to fix the waterstop. By rotating the handle 24, the gear 23 pushes the rack 22, which in turn drives the moving plate 2 to move laterally along the support 1. The clamping groove 21 guides and limits the clamping block 31, causing the moving plate 2 to move the connecting plate 3 laterally. The connecting plate 3 then adjusts the position of the clamping plate 5 in the horizontal direction. When the operator turns on the laser emitter 4, the laser emitted by the laser emitter 4 passes through the transparent end cover 423 and shines on the detection block 32, indicating that the waterstop between the two snap-fit plates 5 is placed in a straight line. During the implementation process, the operator only needs to turn the handle 24 to adjust the distance between the waterstop and the support 1, adjust the horizontal displacement of the waterstop along the lateral direction through the snap-fit plates 5, and achieve precise control of the waterstop displacement through the laser emitter 4. There is no need to use other measuring tools to measure the waterstop, which is conducive to improving the convenience of work.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
