Description

Technical Field

[0001] This application relates to the field of waterstop positioning and tightening technology, and in particular to a waterstop tightening device. Background Technology

[0002] Waterstops are a key component of the waterproofing system in diversion tunnel projects. They are primarily made of flexible materials such as rubber and plastic and are embedded in various joints of the concrete structure. During the construction and long-term operation of the diversion tunnel, the concrete structure undergoes joint deformation. The waterstop, through its own elastic deformation, can tightly adhere to the contact surfaces on both sides of the joint, forming a continuous and reliable sealing barrier. Its working principle utilizes the elastic recovery force of the material to fill the joint gaps, while the structural design, including water-stop teeth and ridges, enhances the bonding effect with the concrete, effectively preventing leakage from the inner wall of the diversion tunnel and water seepage from the surrounding rock.

[0003] The existing waterstop is prone to displacement during subsequent construction after installation, making it difficult to maintain a stable compression state, thus posing a risk of leakage. Summary of the Invention

[0041] See appendix Figure 1 -Appendix Figure 2 , attached Figure 1 -Appendix Figure 2 A schematic diagram of the overall structure of a waterstop clamping device according to an embodiment of this application is shown, including:

[0042] The clamping mechanism 100 includes a frame 110 and a slider 120; the slider 120 is slidably disposed on the frame 110; the frame 110 includes a first clamping part 113, and the slider 120 includes a second clamping part 122, forming a clamping area between the first clamping part 113 and the second clamping part 122; the waterstop is located within the clamping area; the clamping mechanism 100 clamps the waterstop through the first clamping part 113 and the second clamping part 122;

[0043] Multiple clamping components 200, at least some of which are rotatably mounted on the frame 110 and at least some of which are rotatably mounted on the sliding member 120; the multiple clamping components 200 are used to clamp the waterstop after clamping.

[0044] During operation, the waterstop clamping device consists of a clamping mechanism 100 and multiple clamping assemblies 200. The clamping mechanism 100 includes a frame 110 and a sliding member 120, which is slidably engaged with the frame 110. The first clamping part 113 and the second clamping part 122 are arranged opposite to each other to form a clamping area for placing the waterstop. The clamping assemblies 200 are arranged in two groups, with at least a portion rotatably mounted on the frame 110 and the remaining portion rotatably mounted on the sliding member 120, forming a bidirectional clamping structure.

[0045] The waterstop is placed in the clamping area, and the sliding member 120 is driven to slide along the frame 110, causing the second clamping part 122 to move closer to the first clamping part 113. The squeezing force of the two clamping parts is used to clamp and position the waterstop, preventing displacement of the waterstop during subsequent pressing. After the waterstop is clamped, the sets of pressing components 200 assembled on the frame 110 and the sliding member 120 are rotated and adjusted to an angle suitable for the surface of the waterstop. Uniform pressure is applied to the waterstop from both sides of the clamping area to ensure that the waterstop is tightly adhered to the concrete joint.

[0046] In some embodiments, the clamping mechanism 100 opens and closes the clamping part through a sliding fit, which can quickly complete the clamping and positioning of the waterstop. The bidirectionally arranged pressing components 200 can apply pressure simultaneously from both sides, so that the waterstop is subjected to uniform force, avoiding excessive local pressure that could cause damage to the waterstop, while improving the fit between the waterstop and the concrete joint and enhancing the sealing and waterproofing performance.

[0047] See appendix Figure 2 -Appendix Figure 3 The frame 110 has a sliding cavity 111, and the slider 120 is slidably disposed in the sliding cavity 111. The inner wall of the sliding cavity 111 has a groove 112, and the outer wall of the slider 120 includes a slider 121. The slider 121 is located in the groove 112, and the slider 120 is slidably disposed in the sliding cavity 111 through the slider 121.

[0048] In some embodiments, the clamping mechanism 100 of the waterstop clamping device includes a frame 110 and a sliding member 120. The inner wall of the sliding cavity 111 is machined with a groove 112, and the outer wall of the sliding member 120 is correspondingly provided with a slider 121. The slider 121 is fitted into the groove 112 and slides in cooperation with the groove 112 to form a sliding guide structure.

[0049] The frame 110 is provided with a first clamping part 113, and the sliding part 120 is provided with a second clamping part 122. The two clamping parts are arranged opposite to each other to form a clamping area for placing the waterstop.

[0050] In some embodiments, the slider 120 can make a stable linear reciprocating motion along the sliding cavity 111 through the sliding engagement of the slider 121 and the slide groove 112. The fitting structure of the slide groove 112 and the slider 121 can limit the offset of the slider 120 and ensure the guiding accuracy of the sliding process.

[0051] During operation, the drive slider 120 slides along the sliding cavity 111, causing the second clamping part 122 to move closer to the first clamping part 113. The clamping force of the two clamping parts is used to clamp and position the waterstop, preventing the waterstop from shifting during the pressing process. Then, each set of pressing components 200 is rotated and adjusted to an angle that matches the surface of the waterstop, applying uniform pressure to the clamped waterstop to ensure a tight fit between the waterstop and the concrete joint, thus improving the sealing and waterproofing effect.

[0052] See appendix Figure 2 -Appendix Figure 3 The clamping mechanism 100 also includes a reset member 130; the two ends of the reset member 130 are connected to the frame 110 and the sliding member 120 respectively, and the frame 110 and the sliding member 120 are brought closer together by the reset member 130 to clamp the waterstop.

[0053] In some embodiments, the frame 110 and the slider 120 are in a sliding fit structure. The two ends of the reset member 130 are fixedly connected to the frame 110 and the slider 120 respectively. The frame 110 is provided with a first clamping part 113 and the slider 120 is provided with a second clamping part 122. The two clamping parts are arranged opposite to each other to form a clamping area for placing the waterstop.

[0054] The reset component 130 has elastic recovery performance, which can drive the frame 110 and the sliding component 120 to move closer to each other along the sliding direction, and drive the first clamping part 113 and the second clamping part 122 to tighten towards the middle at the same time. The squeezing force of the two clamping parts can automatically clamp the waterstop placed in the clamping area. The clamping state can be maintained without the need to apply additional external force, thus preventing the waterstop from shifting during subsequent pressing operations.

[0055] The elastic restoring force of the reset component 130 can drive the frame 110 and the sliding component 120 to automatically close together, achieving stable clamping of the waterstop without the need for additional manual or power drive devices, simplifying the operation process and improving construction efficiency.

[0056] In some embodiments, the reset member 130 continuously provides clamping force, maintaining the clamping state between the first clamping part 113 and the second clamping part 122, and preventing the waterstop from shifting or slipping during the pressing operation. The elastic deformation characteristics of the reset member 130 can adapt to waterstops of different thicknesses, adjusting the clamping distance through its own elastic expansion and contraction, avoiding sealing failure due to excessively loose clamping or damage to the waterstop due to excessively tight clamping. When removing the waterstop, only external force needs to be applied to overcome the elasticity of the reset member 130 to separate the clamping parts. After releasing the external force, the reset member 130 can automatically reset the clamping parts, facilitating reuse.

[0057] See appendix Figure 2 -Appendix Figure 3 The clamping mechanism 100 also includes a plurality of positioning elements 140; the frame 110 includes a first positioning part 114, and the sliding element 120 includes a second positioning part 123; at least one positioning element 140 is detachably mounted on the first positioning part 114, and at least one positioning element 140 is detachably mounted on the second positioning part 123; the frame 110 and the sliding element 120 are fixedly mounted on the concrete structure by the plurality of positioning elements 140.

[0058] In some embodiments, the clamping mechanism 100 consists of a frame 110, a sliding member 120, and a plurality of positioning members 140. The frame 110 is provided with a first positioning part 114, and the sliding member 120 is provided with a corresponding second positioning part 123. The plurality of positioning members 140 are assembled in a detachable connection manner. At least one positioning member 140 is installed on the first positioning part 114, and at least one positioning member 140 is installed on the second positioning part 123. The positioning members 140 are used to fix the frame 110 and the sliding member 120 together on the concrete structure.

[0059] In some embodiments, before the waterstop tightening operation, the clamping mechanism 100 is placed at the designated construction position of the concrete structure, the positioning member 140 is installed on the first positioning part 114 and the second positioning part 123 respectively, and the positioning member 140 is firmly connected to the concrete structure. Through the rigid limiting effect of the positioning member 140, the displacement of the frame 110 and the sliding member 120 is restricted, ensuring that the clamping mechanism 100 is fixed in the preset position.

[0060] In some embodiments, the positioning element 140 rigidly connects the clamping mechanism 100 to the concrete structure, effectively preventing displacement or shaking of the device during the clamping operation. This ensures the precise clamping position of the first clamping part 113 and the second clamping part 122 on the waterstop, while also ensuring the stable pressure orientation of the clamping assembly 200 on the waterstop, thus improving the sealing quality of the waterstop and the concrete joint. The positioning element 140 features a detachable design, eliminating the need for complex installation procedures and auxiliary tools, allowing for quick fixing and disassembly of the clamping mechanism 100, shortening construction preparation and finishing time, and improving overall construction efficiency. After disassembly, the device can be completely transferred to other construction sites for reuse, reducing overall construction costs. By adjusting the installation position and quantity of the positioning element 140, it can adapt to the construction needs of concrete structures of different specifications and locations, expanding its applicability.

[0061] See appendix Figure 2 -Appendix Figure 3 The positioning element 140 is configured as a positioning pin; both the first positioning part 114 and the second positioning part 123 are provided with insertion holes, and the positioning element 140 is inserted into the insertion holes.

[0062] In some embodiments, the first positioning part 114 and the second positioning part 123 are both machined with insertion holes, and the positioning member 140 is configured as a positioning pin. The positioning pin is detachably inserted into the insertion hole, and the end of the positioning pin away from the insertion hole is used to connect with the concrete structure, thereby fixing the frame 110 and the sliding member 120 to the concrete structure.

[0063] In some embodiments, during construction, the clamping mechanism 100 is placed at a designated position on the concrete structure, the positioning pin is inserted into the insertion holes of the first positioning part 114 and the second positioning part 123, and the other end of the positioning pin is anchored into the preset installation hole of the concrete structure. The rigid support and limiting effect of the positioning pin is used to limit the displacement of the frame 110 and the sliding part 120, ensuring that the clamping mechanism 100 remains stable in position during the clamping and pressing operation of the waterstop.

[0064] After the operation is completed, the clamping mechanism 100 can be released from the concrete structure by simply pulling out the positioning pin, thus enabling the disassembly and transfer of the device.

[0065] In some embodiments, the rigid structure of the locating pin provides reliable positioning constraint, preventing the clamping mechanism 100 from shaking or shifting during pressure application. The plug-in installation method requires no additional tools, allowing for quick fixing and disassembly of the clamping mechanism 100. The locating pin is detachable and its structure is not easily damaged, allowing it to be transferred with the clamping mechanism 100 to multiple construction sites for reuse, reducing equipment investment costs.

[0066] See appendix Figure 2 -Appendix Figure 4The clamping assembly 200 includes a swing member 210 and a pressing member; the swing member 210 is rotatably mounted on the frame 110 and the sliding member 120, and the clamping assembly 200 is rotatably mounted on the frame 110 and the sliding member 120 via the swing member 210; the pressing member is rotatably mounted on the swing member 210, and the clamping assembly 200 clamps the clamped waterstop through the pressing member.

[0067] In some embodiments, the clamping assembly 200 consists of a swing member 210 and a pressing member. The swing member 210 is rotatably mounted on the frame 110 and the sliding member 120, respectively, to realize the rotatable connection between the clamping assembly 200 and the clamping mechanism 100. The pressing member is rotatably mounted on the swing member 210, forming a two-stage rotation structure with the swing member 210. The pressing member is used to directly act on the surface of the waterstop.

[0068] In some embodiments, after the waterstop is clamped and positioned by the clamping mechanism 100, the oscillating member 210 is rotated to adjust its angle relative to the frame 110 and the sliding member 120, so that the extruder is close to the surface of the waterstop. Then, the extruder is rotated to make it fully fit with the surface of the waterstop. Utilizing the rotational characteristics of the extruder itself, the pressure is evenly transmitted to the surface of the waterstop. At the same time, by adjusting the angle of the oscillating member 210, it can adapt to waterstops of different widths and thicknesses as well as different construction joint angles, ensuring that the pressure covers the contact area between the waterstop and the concrete joint.

[0069] In some embodiments, the pressing member can rotate relative to the swing member 210 to form surface contact with the surface of the waterstop, avoiding excessive local pressure that could damage the waterstop, while ensuring a tight fit between the waterstop and the outer wall of the concrete structure. The pressing angle can be adjusted by rotating the swing member 210, eliminating the need for complex adjustment mechanisms and improving construction efficiency.

[0070] See appendix Figure 2 -Appendix Figure 4 The clamping assembly 200 includes a rotating shaft 211; the rotating shaft 211 is rotatably mounted on the swing member 210; the swing member 210 is rotatably mounted on the frame 110 and the sliding member 120 via the rotating shaft 211.

[0071] In some embodiments, the clamping assembly 200 includes a swing member 210 and a rotating shaft 211. The rotating shaft 211 passes through the swing member 210, and its two ends are rotatably connected to the frame 110 and the sliding member 120, respectively. The swing member 210 forms a rotational engagement structure with the frame 110 and the sliding member 120 through the rotating shaft 211. The swing member 210 is also provided with a pressing member for directly acting on the waterstop, thus constituting a complete clamping assembly 200 structure.

[0072] In some embodiments, after the waterstop is clamped and positioned by the clamping mechanism 100, the swing member 210 is driven to rotate around the pivot 211, using the pivot 211 as the fulcrum. The spatial angle of the swing member 210 is adjusted so that the extrusion member mounted on the swing member 210 is close to the surface of the waterstop. By controlling the rotation amplitude of the swing member 210, the surface curvature of the waterstop and the angle of the concrete joint are adapted, and then pressure is applied to the waterstop by the extrusion member to achieve the pressing operation of the waterstop.

[0073] In some embodiments, the pivot 211 provides a stable fulcrum for the swing member 210, preventing the swing member 210 from shifting or jamming during rotation and clamping. The rotation trajectory of the swing member 210 around the pivot 211 is fixed, which allows for adjustment of the clamping angle, ensuring the fit between the extruded part and the surface of the waterstop, and improving the clamping quality.

[0074] See appendix Figure 2 -Appendix Figure 4 The extrusion component is configured as a lead screw 220, and a pressure plate 221 is provided on the side of the lead screw 220 facing the waterstop. The swing component 210 is provided with a threaded hole 212, and the lead screw 220 is threadedly connected in the threaded hole 212. The clamping assembly 200 adjusts the distance between the pressure plate 221 and the waterstop through the lead screw 220.

[0075] In some embodiments, the swing member 210 has a threaded hole 212, the lead screw 220 is threadedly connected to the threaded hole 212, and the pressure plate 221 is fixedly disposed at the end of the lead screw 220 facing the waterstop. The swing member 210 is rotatably assembled to the frame 110 and the sliding member 120 via the rotating shaft 211, forming an adjustable angle clamping structure.

[0076] In some embodiments, after the waterstop is clamped and positioned by the clamping mechanism 100, the swing member 210 is first rotated to adjust to an angle suitable for the surface of the waterstop. Then, by turning the screw 220, the screw 220 is driven to move axially through the threaded transmission relationship between the screw 220 and the threaded hole 212, causing the pressure plate 221 to move closer to or further away from the surface of the waterstop, thus precisely adjusting the distance between the pressure plate 221 and the waterstop. After the pressure plate 221 is in contact with the waterstop, the screw 220 is turned further to apply a preset pressure, so that the waterstop is tightly fitted to the concrete joint.

[0077] In some embodiments, the threaded drive features self-locking and high adjustment precision. By controlling the number of turns of the lead screw 220, the feed amount of the pressure plate 221 can be precisely controlled, achieving quantitative adjustment of the clamping force on the waterstop, preventing damage to the waterstop due to excessive pressure or sealing failure due to insufficient pressure. The axial movement of the lead screw 220 can accommodate waterstops of different thicknesses and concrete joints with varying flatness. The self-locking characteristic of the threaded connection allows the pressure plate 221 to remain in the set position, continuously applying stable pressure without the need for additional locking components.

[0078] See appendix Figure 2 -Appendix Figure 4 The lead screw 220 also includes an adjustment section; the clamping assembly 200 rotates the lead screw 220 through the adjustment section to adjust the distance between the pressure plate 221 and the waterstop.

[0079] In some embodiments, after the waterstop is clamped and positioned by the clamping mechanism 100, the rotating swing member 210 is adjusted to an angle that matches the surface of the waterstop. The screw 220 is driven to rotate around its own axis by the operation adjustment part. The rotational motion of the screw 220 is converted into linear motion along the axial direction by the threaded transmission relationship between the screw 220 and the threaded hole 212. This causes the pressure plate 221 to move closer to or away from the surface of the waterstop, and the distance between the pressure plate 221 and the waterstop is precisely adjusted. After the pressure plate 221 is in contact with the waterstop, the screw 220 is screwed in through the adjustment part to apply a preset clamping force.

[0080] In some embodiments, the adjusting part increases the lever arm of the lead screw 220, reducing the force required to turn the lead screw 220, allowing the operator to easily adjust the pressure and improving operational convenience. By rotating the lead screw 220 through the adjusting part, the number of rotations of the lead screw 220 can be precisely controlled, thereby accurately controlling the feed amount of the pressure plate 221 and achieving quantitative adjustment of the clamping force.

[0081] See appendix Figure 2 -Appendix Figure 3 A rubber gasket is provided on the outer wall of the pressure plate 221 facing the waterstop to protect the waterstop; rubber gaskets are provided on the outer walls of the first clamping part 113 and the second clamping part 122 on the corresponding sides to protect the waterstop; rubber gaskets are provided on the outer walls of the frame 110 and the sliding member 120 facing the waterstop to protect the waterstop; the sliding member 120 includes scale lines, which are used to mark the relative distance between the frame 110 and the sliding member 120.

[0082] In some embodiments, after the waterstop is placed in the clamping area, the slider 120 slides along the frame 110. The operator reads the relative displacement value through the scale line and precisely adjusts the distance between the first clamping part 113 and the second clamping part 122 to adapt to waterstops of different thicknesses.

[0083] During clamping, the rubber pads on the surfaces of the first clamping part 113 and the second clamping part 122 make flexible contact with the waterstop. The rubber pads of the frame body 110 and the sliding member 120 simultaneously adhere to the surface of the waterstop, avoiding damage to the waterstop caused by rigid contact. During the pressing operation, the rubber pads on the surface of the pressure plate 221 press down with the pressure plate 221 to adhere to the waterstop, increasing the contact area while buffering the pressure. Combined with the precise pressure adjusted by the screw 220, the waterstop is tightly adhered to the concrete joint.

[0084] In some embodiments, the rubber gaskets at each location are made of flexible material to prevent rigid components from scratching or damaging the waterstop during clamping and pressing. The scale lines can visually display the relative distance between the frame 110 and the sliding member 120, facilitating the control and recording of the clamping spacing. This ensures uniform clamping force at each location while adapting to waterstops of different thicknesses. Combined with the flexible fit of the rubber gaskets, it improves the sealing fit between the waterstop and the concrete joint.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
