Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a waterproof structure for settlement joints. Background Technology

[0002] Settlement joints are vertical joints designed to prevent damage to buildings caused by uneven settlement of the foundation. When the height, load, and structural form of adjacent buildings in a building complex differ greatly and the foundation is weak, uneven settlement may occur between the buildings, causing cracks in some weak parts. Settlement joints can divide the building complex into several independent units, allowing each unit to settle freely and avoiding damage caused by mutual pulling.

[0003] Traditional embedded waterstops are typically used to prevent seepage and leakage in settlement joints and to provide a certain degree of sealing. However, because waterstops are made of soft material, they are prone to displacement or breakage under external forces (tensile forces generated by uneven settlement between buildings) during use. Once a waterstop is damaged, it needs to be replaced promptly to ensure the waterproofing effect of the settlement joint. In addition, after embedding the waterstop, rigid foam or asphalt-impregnated wood fiberboard is required to be filled above and below it as a sealant. When replacing the waterstop, the sealant must be removed first, then the waterstop must be taken out, and finally the waterstop and sealant must be re-embedded. It can be seen that the entire process of installing and replacing waterstops is quite cumbersome and increases the labor intensity of operators. Summary of the Invention

[0004] To address the aforementioned problems, the main objective of this utility model is to provide a waterproof structure for settlement joints that facilitates waterproof sealing and allows for easy installation and replacement of waterstops.

[0005] To achieve the main objective of this utility model, it provides a waterproof structure for settlement joints, comprising two concrete base slabs forming a settlement joint between them. The settlement joint has a first recessed head at its top, with insertion holes on both side walls. These insertion holes are recessed into the concrete base slabs from the side walls along the width of the settlement joint. The waterproof structure includes a waterproof unit, comprising a waterstop, a cover plate, a first pressing mechanism, and a locking mechanism. The waterstop is laid at the bottom of the first recessed head. The cover plate covers the opening of the first recessed head. The first pressing mechanism includes a control lever, a push block, and a pressure plate. The control lever passes through the cover plate and is parallel to the height direction of the settlement joint. The push block connects the control lever and the pressure plate, and the control lever can control the pressure plate to press firmly onto the waterstop. The locking mechanism includes a rod that is slidably connected to the cover plate along its width. The first end of the rod is linked to the push block, and the push block can control the second end of the rod to insert into the insertion hole or disengage from the insertion hole.

[0006] As can be seen from the above, the waterproof unit can be fastened to the concrete base plate with the cooperation of the cover plate, the first pressing mechanism, the locking mechanism, and the insertion hole. The cover plate prevents external dust and foreign objects from entering the settlement joint, and also blocks external water from flowing into the settlement joint. The waterstop is sealed to the bottom of the first settlement head under the action of the first pressing mechanism to prevent water from flowing to the bottom of the settlement joint and ensure the waterproof effect. The cooperation between the first pressing mechanism and the locking mechanism can realize the quick assembly and disassembly of the waterproof unit and the quick replacement of the waterstop, reducing the difficulty of waterstop replacement, improving the efficiency of waterstop replacement, and reducing the labor intensity of workers.

[0007] A preferred embodiment is that, in the width direction, both sides of the waterstop have L-shaped bends; the bends have vertical sections and horizontal sections, the vertical sections connecting the body of the waterstop and the horizontal sections, and the horizontal sections of the two bends extending in opposite directions in the width direction; the bottom of the first recessed head has a stepped portion at the side wall, the body of the waterstop covers the bottom of the first recessed head, and the horizontal section covers the top of the stepped portion; the waterproof unit also includes a second pressing mechanism, the second pressing mechanism including a mounting bracket, a first compression spring and a pressing member, the mounting bracket being mounted on the pressure plate, the first compression spring connecting the mounting bracket and the pressing member, the first compression spring forcing the pressing member to press against the horizontal section.

[0008] As can be seen from the above, the combination of the bending part, the stepped part and the second clamping mechanism can achieve two-stage sealing of the settlement joint to improve the waterproof sealing effect, and at the same time help to ensure the reliability of fixing the waterstop.

[0009] A further embodiment is that the second clamping mechanism also includes a guide rod, which is mounted on the mounting bracket. A first compression spring is sleeved on the guide rod, and the height of the guide rod is less than the height of the first compression spring in its natural state. And / or a positioning post is provided on the step portion, and a positioning hole is provided on the transverse section, with the positioning post inserted into the positioning hole.

[0010] As can be seen above, the guide rod is used to guide and limit the first compression spring to prevent it from bending under the pressure of the mounting bracket and clamping parts, thereby ensuring the clamping effect of the second clamping mechanism on the horizontal section of the waterstop. The cooperation between the positioning post on the step and the positioning hole on the horizontal section can realize the quick positioning and limiting of the waterstop, which facilitates the installation of the waterstop and prevents the waterstop from shifting during the installation of the clamping mechanism, locking mechanism and cover plate.

[0011] A further improvement is that the side of the pressure plate facing the waterstop has a protrusion, and the main body can be pressed between the bottom of the first sinker head and the protrusion.

[0012] As can be seen from the above, under the action of the protrusion, the waterstop can be tightly pressed against the bottom of the first sinker, thereby ensuring the waterproof effect.

[0013] Another preferred embodiment is that the top of the first sinker is formed with a second sinker, and a cover plate is located inside the second sinker; a sealing gasket is provided between the cover plate and the bottom of the second sinker.

[0014] As can be seen from the above, placing the cover plate inside the second bearing head can not only prevent the cover plate from being excessively exposed outside the concrete base plate, but also help prevent external water from entering the settlement joint; and adding a sealing gasket between the bottom of the cover plate and the second bearing head can further improve the sealing effect of the waterproof unit on the settlement joint.

[0015] Another preferred embodiment is that, in the width direction, locking mechanisms are provided on both sides of the push block; the push block is frustum-shaped, and the first end of the insertion rod contacts the side of the push block; or the push block is trapezoidal column-shaped, with two waist sides of the push block distributed along the width direction, the waist sides contacting the first end of the insertion rod, and the upper bottom of the push block connected to the pressure plate.

[0016] As can be seen from the above, the locking mechanism on both sides of the push block can ensure the reliability of the connection between the waterproof unit and the concrete base plate and improve the waterproof effect of the waterproof unit; the design of the push block makes it easier to drive the plug rod into the socket.

[0017] A further embodiment is that the first end of the insertion rod is provided with a roller, the axis of which is parallel to the extension direction of the settlement joint; when the push block is frustum-shaped, the push block is provided with a first guide limiting groove along its own generatrix at each insertion rod, and a part of the roller is located in the first guide limiting groove; when the push block is trapezoidal column-shaped, the waist side of the push block is recessed to form a second guide limiting groove, and a part of the roller is located in the second guide limiting groove.

[0018] As can be seen from the above, the roller can reduce the friction between the insertion rod and the push block, so that the push block can smoothly drive the insertion rod to be inserted into the insertion hole. With the design of the guide limit groove, the reliability of the linkage between the roller and the push block can be guaranteed.

[0019] Another further option is that the control lever is fixed relative to the cover plate in the height direction, and the control lever can rotate relative to the cover plate around its own axis. The control lever is provided with a threaded section, which is threadedly connected to the push block; and / or an operating handwheel is provided at the end of the control lever located outside the settlement joint.

[0020] As can be seen above, by connecting the control lever to the push block by thread, the clamping force of the pressure plate on the waterstop can be adjusted, avoiding the pressure plate relying solely on its own pressure to clamp and fix the waterstop, thus improving the sealing effect of the waterproof unit.

[0021] Another preferred embodiment is that the cover plate is provided with a connecting block, the insert rod is slidably connected to the connecting block, the insert rod is provided with a limiting block, the limiting block is located between the push block and the connecting block, and the locking mechanism includes a second compression spring, the second compression spring is sleeved on the insert rod, and the second compression spring abuts between the connecting block and the limiting block; or the first end of the insert rod is provided with a slider, when the push block is frustum-shaped, the push block is provided with a first groove along its own generatrix at each insert rod, and the slider is slidably connected to the first groove; when the push block is trapezoidal column-shaped, the waist side of the push block is recessed to form a second groove, and the slider is slidably connected to the second groove; and / or one of the cover plate and the pressure plate is provided with a guide rail and the other is provided with a guide post, the guide rail has a guide groove parallel to the height direction, and the guide post is slidably inserted in the guide groove.

[0022] As can be seen from the above, the design ensures that when the waterproof unit is disassembled, the insert rod can automatically disengage from the socket under the action of the second compression spring as the push block moves upward, thus ensuring that the waterproof unit can be disassembled.

[0023] A further option is to have two or more waterproof units, which are distributed along the extension direction of the settlement joint, with a seal between adjacent waterproof units; and to have a socket on the side wall that mates with each waterproof unit.

[0024] As can be seen from the above, the number of waterproof units can be designed according to the length of the settlement joint. At the same time, this design can avoid a single waterproof unit being too large, making the processing, production and installation of the waterproof unit more convenient, and ensuring a more uniform pressure on the waterstop, thus guaranteeing the waterproof sealing effect.

[0033] Example of a waterproof structure for settlement joints

[0034] Reference Figure 1 and Figure 2 The settlement joint waterproof structure 100 includes two concrete base slabs 101 and a waterproof unit 102. Combined with... Figure 3 A settlement joint 1011 is formed between two concrete base slabs 101. The top of the settlement joint 1011 has a first recessed head 1012. The two side walls of the first recessed head 1012 are provided with insertion holes 10120, that is, each concrete base slab 101 is provided with insertion holes 10120. The insertion holes 10120 are recessed from the side wall of the first recessed head 1012 into the concrete base slab 101 where the side wall is located in the width direction of the settlement joint 1011.

[0035] Combination Figure 4 The waterproof unit 102 includes a waterstop 1, a cover plate 2, a first pressing mechanism 3 and a locking mechanism 4; the waterstop 1 is laid at the bottom of the first recessed head 1012 so that the waterstop 1 can seal the settlement joint 1011 below the first recessed head 1012 to achieve a waterproof effect.

[0036] The cover plate 2 covers the opening of the first sink head 1012 to seal the opening of the first sink head 1012, thereby preventing external foreign objects, dust and other objects from entering the settlement joint 1011. The cover plate 2 can also block external water from flowing into the settlement joint 1011 to a certain extent.

[0037] In some embodiments, a second recessed head 1013 is formed on the top of the first recessed head 1012, that is, the second recessed head 1013 is formed at the opening of the first recessed head 1012, and the projection of the first recessed head 1012 is located within the projection of the second recessed head 1013 in the height direction of the settlement joint 1011. In this case, after the waterproof unit 102 is installed, the cover plate 2 is located inside the second recessed head 1013. Preferably, the top surface of the cover plate 2 is flush with the top surface of the concrete base slab 101. This design avoids the cover plate 2 being excessively exposed outside the concrete base slab 101 and further helps to prevent external water from flowing into the settlement joint 1011. Based on this, in some embodiments, a sealing gasket can be provided between the cover plate 2 and the bottom of the second recessed head 1013. The sealing gasket can improve the sealing effect between the cover plate 2 and the second recessed head 1013, so as to better prevent external water from flowing into the settlement joint 1011 from the gap between the cover plate 2 and the second recessed head 1013.

[0038] The first pressing mechanism 3 includes a control lever 31, a push block 32, and a pressure plate 33. The control lever 31 passes through the cover plate 2 and is parallel to the height direction of the settlement joint 1011. The push block 32 and the pressure plate 33 are both located inside the first recessed head 1012, and the push block 32 is connected between the control lever 31 and the pressure plate 33, so that the control lever 31 can control the pressure plate 33 to press against the waterstop 1 to ensure a sealing effect.

[0039] In this embodiment, the control lever 31 is relatively fixed to the cover plate 2 in the height direction of the settlement joint 1011, and the control lever 31 can rotate relative to the cover plate 2 around its own axis. The control lever 31 has a threaded section that is threadedly connected to the push block 32, which is fixedly connected to the pressure plate 33. This allows the pressure plate 33 to move relative to the waterstop 1 by rotating the control lever 31. This design makes the clamping force of the pressure plate 33 on the waterstop 1 adjustable, avoiding the pressure plate 33 relying solely on its own pressure to clamp and fix the waterstop 1, thus improving the sealing effect of the waterproof unit 102. Preferably, an operating handwheel 311 is provided at the end of the control lever 31 located outside the settlement joint 1011, allowing the user to operate the control lever 31 to rotate.

[0040] Combination Figure 5 In some embodiments, one of the cover plate 2 and the pressure plate 33 is provided with a guide rail 22 and the other is provided with a guide post 332. The guide rail 22 has a guide groove 221 parallel to the height direction of the settlement joint 1011, and the guide post 332 is slidably inserted in the guide groove 221. In this embodiment, the cover plate 2 is provided with a guide rail 22, and the pressure plate 33 is provided with a guide post 332. As an optional solution, each guide rail section 22 has two guide grooves 221, which are arranged in a mirror-symmetrical manner along the length of the settlement joint 1011. The cross-section of the guide groove 221 can be T-shaped, and correspondingly, the cross-section of the guide post 332 is also T-shaped. Of course, as another optional solution, the cross-section of the guide groove 221 can also be square, and correspondingly, the cross-section of the guide post 332 is also square. By designing the position and cross-sectional shape of the guide groove 221, the guide groove 221 and the guide post 332 can guide the movement of the pressure plate 33 in the height direction of the settlement joint 1011, and limit the pressure plate 33 in the length and width directions of the settlement joint 1011.

[0041] Combination Figure 6To improve waterproofing and sealing performance, bends 11 can be provided on opposite sides of the waterstop 1 in the width direction of the settlement joint 1011. The bends 11 are L-shaped, meaning they have a vertical section 111 and a horizontal section 112. The vertical section 111 connects the main body 10 of the waterstop 1 and the horizontal section 112, preferably parallel to the height direction of the settlement joint 1011. The horizontal sections 112 of the two bends 11 extend in opposite directions in the width direction of the settlement joint 1011. Correspondingly, the bottom of the first recessed head 1012 has a step 10121 on its sidewall. When the waterstop 1 is installed, the main body 10 of the waterstop 1 covers the bottom of the first recessed head 1012, and the horizontal section 112 covers the top of the step 10121. Based on this, the waterproof unit 102 also includes a second pressing mechanism 5, which is used to press the horizontal section 112. It can be understood that the second pressing mechanism 5 is provided at the horizontal section 112 on both sides of the waterstop 1. The second clamping mechanism 5 includes a mounting bracket 51, a first compression spring 52, a clamping member 53, and a guide rod 54. The mounting bracket 51 is mounted on the pressure plate 33. Preferably, the mounting bracket 51 is L-shaped, meaning it has a vertical portion 511 and a horizontal portion 512. The vertical portion 511 connects the pressure plate 33 and the horizontal portion 512, and the horizontal portion 512 extends from the vertical portion 511 in the same extending direction as the horizontal segment 112. The first compression spring 52 is mounted on the horizontal portion 512 and is located between the horizontal portion 512 and the horizontal segment 112. The clamping member 53 is connected to the extended end of the first compression spring 52, that is, the first compression spring 52 is connected between the horizontal segment 112 and the clamping member 53, so that the first compression spring 52 forces the clamping member 53 to press against the horizontal segment 112. Yes, the clamping member 53 can be ring-shaped, block-shaped, or strip-shaped. When the clamping member 53 is strip-shaped, the strip-shaped clamping member 53 extends along the length direction of the settlement joint 1011 so that the clamping member 53 can clamp and fix the entire horizontal section 112 of the waterstop 1. The guide rod 54 is installed on the horizontal part 512 and is parallel to the height direction of the settlement joint 1011. The first compression spring 52 is sleeved on the guide rod 54, and the height of the guide rod 54 is less than the height of the first compression spring 52 in its natural state. The guide rod 54 is used to guide and limit the first compression spring 52 to prevent the first compression spring 52 from bending under the compression of the mounting frame 51 and the clamping member 53, thereby ensuring the clamping effect of the second clamping mechanism 5 on the horizontal section 112 of the waterstop 1. This design enables the bending part 11, the step part 10121 and the second pressing mechanism 5 to achieve a two-stage seal on the settlement joint 1011, thereby improving the waterproof sealing effect and also helping to ensure the reliability of fixing the waterstop 1.

[0042] Based on the foregoing, in some embodiments, a positioning post 10122 is provided on the step portion 10121, and the positioning post 10122 is parallel to the height direction of the settlement joint 1011; correspondingly, a positioning hole 1121 is provided on the transverse section 112 of the waterstop 1. When the waterstop 1 is installed, the positioning post 10122 is inserted into the corresponding positioning hole 1121. This design can realize the rapid positioning and limiting of the waterstop 1, thereby facilitating the installation of the waterstop 1 and preventing the waterstop 1 from shifting during the installation of the first pressing mechanism 3, the locking mechanism 4 and the cover plate 2. In this embodiment, the clamping member 53 is preferably annular. When the clamping member 53 is pressed onto the horizontal section 112, it is sleeved on the positioning post 10122 to avoid obstructing the positioning post 10122. Alternatively, a connecting strip can be provided between two adjacent clamping members 53, allowing the connecting strip to also be pressed onto the horizontal section 112 along with the clamping member 53, ensuring a tight clamping effect on the entire horizontal section 112 and thus improving the waterproof sealing effect of the two-section seal. The sum of the heights of the guide rod 54 and the positioning post 10122 is less than the height of the first compression spring 52 in its natural state.

[0043] Furthermore, the pressure plate 33 has a protrusion 331 on the side facing the waterstop 1. When the pressure plate 33 is pressed against the main body 10 of the waterstop 1, the main body 10 can be pressed between the bottom of the first recessed head 1012 and the protrusion 331. The protrusion 331 enables the main body 10 to be pressed more tightly against the bottom of the first recessed head 1012, thereby ensuring the waterproof effect.

[0044] The locking mechanism 4 includes a rod 41, which is slidably connected to the cover plate 2 in the width direction of the settlement joint 1011. The first end of the rod 41 is linked with the push block 32, so that the push block 32 can control the second end of the rod 41 to be inserted into the insertion hole 10120 or to be dislodged from the insertion hole 10120. Preferably, locking mechanisms 4 are provided on both sides of the push block 32 in the width direction of the settlement joint 1011 to ensure the reliability of the connection between the waterproof unit 102 and the concrete base plate 101 and improve the waterproof effect of the waterproof unit 102.

[0045] Combination Figure 7In this embodiment, the push block 32 is frustum-shaped, with its upper bottom connected to the pressure plate 33. The first end of the insertion rod 41 contacts the side of the push block 32. The design of the push block 32 allows it to more easily drive the insertion rod 41 into the insertion hole 10120. To reduce the friction between the insertion rod 41 and the push block 32 and to allow the push block 32 to smoothly drive the insertion rod 41 into the insertion hole 10120, a roller 412 is provided on the first end of the insertion rod 41. The axis of the roller 412 is parallel to the extension direction of the settlement joint 1011 (i.e., the length direction of the settlement joint 1011). Furthermore, the push block 32 can be provided with a first guide limiting groove 321 at each insertion rod 41. The first guide limiting groove 321 extends along the generatrix of the frustum-shaped push block 32, and a part of the roller 412 is located in the first guide limiting groove 321. This design can guide and limit the roller 412 and ensure the reliability of the linkage between the roller 412 and the push block 32. In addition, the cover plate 2 is provided with a connecting block 21, and the insertion rod 41 is slidably connected to the connecting block 21. The connecting block 21 is used to limit and support the insertion rod 41. Preferably, the connecting block 21 can be integrated with the guide rail part 22. That is, the component after the connecting block 21 and the guide rail part 22 are integrated can be used as both the connecting block 21 and the guide rail part 22. Furthermore, a limiting block 411 is provided on the insertion rod 41, which is located between the push block 32 and the connecting block 21; the locking mechanism 4 includes a second compression spring 42, which is sleeved on the insertion rod 41 and abuts between the connecting block 21 and the limiting block 411. The design ensures that when the waterproof unit 102 is disassembled, as the push block 32 moves upward, the insertion rod 41 can automatically disengage from the insertion hole 10120 under the action of the second compression spring 42, ensuring that the waterproof unit 102 is detachable.

[0046] In some embodiments, the frustum-shaped pusher block 32 can be modified into a trapezoidal column shape, wherein the two sidewalls of the trapezoidal column-shaped pusher block 32 are distributed along the width direction of the settlement joint 1011, and the sidewalls contact the roller 412 at the first end of the insertion rod 41. Similarly, the sidewalls of the trapezoidal column-shaped pusher block 32 can be recessed into the pusher block 32 to form a second guide limiting groove, and correspondingly, a portion of the roller 412 is located within the second guide limiting groove.

[0047] Of course, as another optional solution, in other embodiments, the cross-section of the first guide limiting groove 321 or the second guide limiting groove can be set to a T-shape, so that the first guide limiting groove 321 becomes a first sliding groove, or the second guide limiting groove becomes a second sliding groove. At the same time, the roller 412 at the first end of the insertion rod 41 is set as a T-shaped block (i.e., a slider). The T-shaped block is used for the cooperation and connection of the first guide limiting groove 321 or the second guide limiting groove. This design can also make the push block 32 drive the pressure plate 33 to press against the waterstop 1 simultaneously. Push the insertion rod 41 to insert its second end into the insertion hole 10120, or pull the insertion rod 41 to disengage its second end from the insertion hole 10120 when the push block drives the pressure plate 33 to release the pressure on the waterstop 1. However, this design may cause a certain friction between the push block 32 and the insertion rod 41, making the smoothness of the push block 32 driving the insertion rod 41 to move worse than the smoothness of the push block 32 cooperating with the roller 412 to drive the insertion rod 41. In addition, based on this scheme, the locking mechanism 4 can also eliminate the design of the second compression spring 42 and the upper limit block 411 of the insertion rod 41.

[0048] In some embodiments, the number of waterproof units 102 is two or more, and the two or more waterproof units 102 are distributed along the extension direction of the settlement joint 1011. A sealing element is provided between two adjacent waterproof units 102. Correspondingly, an insertion hole 10120 that mates with each waterproof unit 102 is provided on the side wall. As can be seen from this design, the number of waterproof units 102 can be designed according to the length of the settlement joint 1011. At the same time, this design can avoid a single waterproof unit 102 being too large, making the processing, production and installation of the waterproof unit 102 more convenient, and ensuring a more uniform clamping force on the waterstop 1, thus guaranteeing the waterproof sealing effect.

[0049] The following is a brief description of the installation and replacement of waterstop 1:

[0050] When the waterproof unit 102 needs to be installed, the waterstop 1 is first installed into the settlement joint 1011. During installation, the main body 10 of the waterstop 1 is laid over the bottom of the first recessed head 1012, and the horizontal section 112 of the waterstop 1 is laid on the step 10121. At the same time, ensure that the positioning post 10122 on the step 10121 is inserted into the positioning hole 1121 on the horizontal section 112 to complete the positioning of the waterstop 1.

[0051] Next, the cover plate 2 is installed into the second recessed head 1013, so that the first pressing mechanism 3, the locking mechanism 4, and the second pressing mechanism 5 are all located within the first recessed head 1012. Then, the operating lever 31 is rotated, causing the operating lever 31 to drive the pressure plate 33 through the push block 32 to press the main body 10 of the waterstop 1 against the bottom of the first recessed head 1012. At the same time, the first compression spring 52 forces the pressing member 53 to press against the transverse section 112 of the waterstop 1. Simultaneously, the push block 32 pushes the second end of the insertion rod 41 into the insertion hole 10120 to lock the waterproof unit 102 onto the concrete base plate 101. At this time, the second compression spring 42 is in a compressed state.

[0052] When the waterstop 1 needs to be replaced, rotate the control lever 31 so that the control lever 31 drives the pressure plate 33 to move upward through the push block 32 to release the pressure on the main body 10 of the waterstop 1. At the same time, the second pressing mechanism 5 moves upward with the pressure plate 33 so that the pressing member 53 releases the pressure on the horizontal section 112 of the waterstop 1. Meanwhile, as the push block 32 moves upward, the insertion rod 41 gradually disengages from the insertion hole 10120 under the action of the second compression spring 42. When the insertion rod 41 gradually disengages from the insertion hole 10120, the cover plate 2, together with the first pressing mechanism 3, the locking mechanism 4 and the second pressing mechanism 5, can be removed from the settlement joint 1011. Then, repeat the above installation of the waterproof unit 102 to complete the replacement of the waterstop 1.

[0053] In summary, the waterproof unit 102, with the cooperation of the cover plate 2, the first pressing mechanism 3, the locking mechanism 4, and the insertion hole 10120, can be fastened to the concrete base plate 101.
