Technical Field

[0001] This application relates to the field of post-cast strip technology, and in particular to pre-sealed structures for settlement post-cast strips and their construction methods. Background Technology

[0002] Currently, post-cast strips are actually used in construction to prevent cracks caused by uneven shrinkage of reinforced concrete during in-situ casting or by settlement later on.

[0003] The relevant technology can be found in Chinese invention patent CN217500603U, which discloses a pre-sealed structure for a settlement post-cast strip. This structure includes a settlement post-cast strip pre-installed on the top slab, flanges on both sides of the settlement post-cast strip, and a cover plate covering the flanges. The cover plate consists of multiple pieces, sequentially spliced ​​along the post-cast strip. A waterstop strip is installed at the joint between adjacent cover plates, and the joint is sealed with sealant. The flanges extend above the top slab and are made of reinforced concrete. The wire mesh of the flanges is embedded within the top slab. A waterstop strip is installed at the joint between the cover plate and the flanges, and the joint is sealed with sealant. Steel pipes are pre-embedded in some of the cover plates, and multiple steel pipes are evenly arranged.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: before pouring the post-settlement pouring strip, it is necessary to cut the steel pipe, which affects the construction efficiency of pouring the post-settlement pouring strip. Summary of the Invention

[0005] To improve the efficiency of casting post-settlement strips, this application provides a pre-sealed structure for post-settlement strips and its construction method.

[0006] Firstly, the pre-sealed structure for settlement post-cast strips provided in this application adopts the following technical solution: The pre-sealed structure of the settlement strip includes flanges cast on both sides of the settlement strip. Multiple cover plates are provided on the flanges. Through grooves are opened on the cover plates. Insert pipes are fixedly connected to the inner wall of the through grooves. Each cover plate is provided with multiple sets of sealing mechanisms for sealing the insert pipes. The insertion tube has multiple through slots, and the casting pipe inserted into the insertion tube has multiple sliding blocks fixedly connected to it. The sliding blocks correspond one-to-one with the through slots, and the sliding blocks are slidably connected to the inner wall of the through slots. The sealing mechanism includes a sealing plate, a sliding rod, and a first piston. The cover plate has a through groove, a sliding hole, and a first clearance groove that are connected. The sliding rod is slidably connected to the inner wall of the sliding hole. One end of the sliding rod is located in the through groove, and the other end of the sliding rod is located in the first clearance groove. The sealing plate is fixedly connected to the sliding rod and abuts against the insertion pipe. The sealing plate can move into the first clearance groove. The first piston is fixedly connected to the sliding rod and is slidably connected to the inner wall of the through groove. The sealing mechanism also includes a push assembly for moving the first piston; The sealing mechanism also includes an opening and closing component for moving the sealing plate into the first clearance groove.

[0007] By adopting the above technical solution, in order to improve the efficiency of pouring the settlement strip, after the cover plate is placed on the flange, the first piston is moved by the pushing component. The movement of the first piston drives the sliding rod and the sealing plate to move, so that the sealing plate abuts against the insertion pipe to close the insertion pipe. After the main building has settled and stabilized, the pouring pipe is inserted into the insertion pipe, so that the sliding block moves along the extension direction of the through groove. Then, the opening and closing component is used to move the sealing plate into the first clearance groove, thereby opening the insertion pipe and facilitating the pouring of the settlement strip.

[0008] Preferably, the pushing assembly includes a second piston, a pushing rod, and a vertical rod. A vertical groove is formed on the inner wall of the through groove. The vertical rod is slidably connected to the inner wall of the vertical groove. The pushing rod is slidably connected to the inner wall of the through groove. The second piston is fixedly connected to the pushing rod. A first inclined surface is provided on the pushing rod. The first inclined surface is inclined downward from the end away from the second piston to the end close to the second piston. The vertical rod abuts against the pushing rod.

[0009] By adopting the above technical solution, during the process of placing the cover plate on the flange, when the vertical rod contacts the flange, the vertical rod moves and pushes the push rod to move, and the push rod moves and drives the second piston to move, thereby causing the first piston to move.

[0010] Preferably, the opening and closing assembly includes a moving rod, a sealing block, a compression spring, and a tension spring. The inner wall of the through groove has a communicating sealing groove, a vent hole, and a moving groove. The sealing block is slidably connected to the inner wall of the sealing groove. One end of the compression spring is fixedly connected to the sealing block, and the other end is fixedly connected to the inner wall of the sealing groove. The vent hole communicates with the outside of the cover plate. The moving groove communicates with the through groove. The moving rod is slidably connected to the inner wall of the moving groove. One end of the moving rod has a second inclined surface, which slopes downwards from the end near the sealing block to the end away from the sealing block. The side wall of the through groove has a communicating hole communicating with the moving groove. The moving rod passes through the communicating hole, and the sliding block abuts against the moving rod. The other end of the moving rod has a third inclined surface, which slopes downwards from the end away from the sealing block to the end near the sealing block. The sealing block has a through hole, and the moving rod abuts against the inner wall of the through hole.

[0011] By adopting the above technical solution, when the sliding block contacts the moving rod, it pushes the moving rod to move away from the pouring pipe, thereby pushing the sealing block to move, so that the vent hole is connected to the through groove. Since the air pressure between the first piston and the second piston is consistent with the atmospheric pressure, the tension spring can pull the sealing plate to move closer to the first piston. After the sealing plate moves into the first clearance groove, the insertion pipe is opened.

[0012] Preferably, the cover plate is further provided with multiple sets of limiting mechanisms, each of which corresponds to a sealing mechanism. Each limiting mechanism includes a fixed base and a limiting rod. The fixed base is fixedly connected to the cover plate, and a first sliding groove is provided on the fixed base. The limiting rod is slidably connected to the inner wall of the first sliding groove, a fixed ring is fixedly connected to the limiting rod, and a limiting spring is sleeved on the limiting rod. One end of the limiting spring is fixedly connected to the fixed ring, and the other end of the limiting spring is fixedly connected to the fixed base. A groove is provided on the flange, and the limiting rod is inserted into the groove. The limiting mechanism also includes a clamping component for releasing the limiting rod from its limit position; The limiting mechanism also includes a pulling component for moving the limiting rod.

[0013] By adopting the above technical solution, the clamping component is used to release the limit rod. Then, the limit spring pushes the fixing ring and the limit rod to move, so that the limit rod is inserted into the groove, thereby fixing the cover plate on the flange. By using the pulling component, the limit rod is pulled to disengage from the groove, thus releasing the limit of the cover plate.

[0014] Preferably, the clamping assembly includes a clamping block, a clamping spring, and a pulling member. A second sliding groove is formed on the inner wall of the first sliding groove. The clamping block is slidably connected to the inner wall of the second sliding groove. One end of the clamping spring is fixedly connected to the clamping block, and the other end of the clamping spring is fixedly connected to the inner wall of the second sliding groove. A slot is formed on the limiting rod, and the clamping block can be inserted into the slot. The pulling member is disposed on the cover plate, and the pulling member can pull the clamping block to move away from the limiting rod.

[0015] By adopting the above technical solution, during the closing process of the insertion pipe, the pulling component pulls the locking block to move away from the limiting rod, causing the locking block to disengage from the locking groove, thereby releasing the limiting rod.

[0016] Preferably, the pulling member includes a long rod, a connecting block, and an elastic rope. A second clearance groove is formed on the bottom wall of the first clearance groove. The connecting block is fixedly connected to the sliding rod and can move along the extension direction of the second clearance groove. The long rod is fixedly connected to the connecting block. A through groove is formed on the fixed seat. One end of the long rod is slidably connected to the inner wall of the through groove. One end of the elastic rope is fixedly connected to the long rod, and the other end of the elastic rope is fixedly connected to the locking block. A portion of the elastic rope passes through the fixed seat, and the elastic rope is deformable.

[0017] By adopting the above technical solution, the sliding rod moves, causing the connecting block and the long rod to move. The movement of the long rod causes the elastic rope to tighten, and then the elastic rope pulls the locking block to move, causing the locking block to move away from the limit rod.

[0018] Preferably, the pulling assembly includes a pulling rod and a pulling rope. The fixed base has a placement groove. The pulling rod is slidably connected to the inner wall of the placement groove. One end of the pulling rope is fixedly connected to the pulling rod, and the other end of the pulling rope is fixedly connected to the limiting rod. The pulling rope is deformable. The pulling assembly also includes a drive component for moving the pulling rod.

[0019] By adopting the above technical solution, the driving component pushes the pull rod to move away from the fixed seat. The movement of the pull rod causes the pull rope to tighten. Then the pull rope drives the limit rod to move. When the locking block is aligned with the locking slot, the locking spring pushes the locking block to move, so that the locking block is inserted into the locking slot, thereby fixing the limit rod.

[0020] Preferably, the driving component includes a first rack, a gear, and a second rack. The first rack is fixedly connected to the long rod, and a support is fixedly connected to the fixed seat. The gear is rotatably connected to the support seat. The first rack meshes with the gear. The second rack is fixedly connected to the pulling rod and meshes with the gear.

[0021] By adopting the above technical solution, the movement of the long rod drives the first rack to move, thereby causing the gear to rotate, and the rotation of the gear causes the second rack and the pulling rod to move.

[0022] Preferably, the fixed base is rotatably connected to the guide wheel, and the elastic rope abuts against the guide wheel.

[0023] By adopting the above technical solution, the friction between the elastic rope and the fixed seat is reduced by using the guide wheel, thereby improving the safety of the elastic rope.

[0024] Secondly, the construction method for the pre-sealed structure of the settlement post-cast strip provided in this application adopts the following technical solution.

[0025] The construction method for the pre-sealed structure with settlement strip includes the following steps: S1. After settlement, pour flanges on both sides of the pouring strip; S2. Place multiple cover plates on the flange in sequence to ensure a tight connection between adjacent cover plates; S3. After the main building has settled and stabilized, insert the pouring pipe into the insertion pipe and pour concrete into the settlement strip.

[0026] By adopting the above technical solution, since there is no need to cut the pipe, the casting pipe can be directly inserted into the insertion pipe to cast the settlement strip, thus improving the efficiency of casting the settlement strip.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. In order to improve the efficiency of pouring the settlement strip, after the cover plate is placed on the flange, the first piston is moved by the pushing component. The movement of the first piston drives the sliding rod and the sealing plate to move, so that the sealing plate abuts against the insertion pipe to close the insertion pipe. After the main building has settled and stabilized, the pouring pipe is inserted into the insertion pipe, so that the sliding block moves along the extension direction of the through groove. Then, the opening and closing component is used to move the sealing plate into the first clearance groove, thereby opening the insertion pipe, which facilitates the pouring of the settlement strip and shortens the pouring time of the settlement strip. 2. Using the clamping assembly, the limiting rod is released from its position. Then, the limiting spring pushes the fixing ring and the limiting rod to move, so that the limiting rod is inserted into the groove, thereby fixing the cover plate to the flange. Using the pulling assembly, the limiting rod is pulled to disengage from the groove, thus releasing the limiting of the cover plate and reducing the possibility of the cover plate falling off the flange. 3. During the closing process of the insertion pipe, the pulling component pulls the locking block to move away from the limit rod, causing the locking block to disengage from the locking groove, thereby releasing the limit rod. Then, after the settlement strip is poured, the cover plate can be removed for reuse. Attached Figure Description

Part of the elastic rope 73 passes through the fixed seat 61. The elastic rope 73 can deform. The fixed seat 61 is rotatably connected to the guide wheel 74. The elastic rope 73 abuts against the guide wheel 74. The guide wheel 74 reduces the friction between the elastic rope 73 and the fixed seat 61, thereby improving the safety of the elastic rope 73.

[0043] The pulling assembly 8 includes a pulling rod 81, a pulling rope 82, and a driving component 83. A placement groove 614 is provided on the fixed base 61.

[0045] To improve the efficiency of pouring the post-settlement strip 11, after the flange 1 is poured, the cover plate 2 is placed on the flange 1. During the placement of the cover plate 2, when the vertical rod 47 contacts the flange 1, the vertical rod 47 moves. The movement of the vertical rod 47 pushes the push rod 46 to move, and the movement of the push rod 46 drives the second piston 45 to move. Since the first piston 43 and the second piston 45 are sealed, the movement of the second piston 45 causes the first piston 43 to move. The movement of the first piston 43 drives the sliding rod 42 and the sealing plate 41 to move, so that the sealing plate 41 abuts against the opening of the insertion pipe 3, thereby improving the sealing performance of the post-settlement strip 11. After the main building has settled and stabilized, the pouring pipe 12 is inserted into the insertion pipe. Inside the pipe 3, the sliding block 13 moves along the through groove 31. When the sliding block 13 contacts the moving rod 51, it pushes the moving rod 51 to move. Since the moving rod 51 abuts against the inner wall of the through hole 521, the moving rod 51 moves and pushes the sealing block 52 to move, so that the vent hole 27 is connected to the through groove 22, thereby making the air pressure in the first piston 43 and the second piston 45 consistent with the atmospheric pressure. Then the tension spring 54 can pull the sealing plate 41 to move closer to the first piston 43. After the sealing plate 41 moves into the first clearance groove 24, the insertion pipe 3 is opened. At this time, the concrete is poured into the settlement strip 11 through the pouring pipe 12, completing the pouring of the settlement strip 11.

[0046] During the process of placing the cover plate 2 onto the flange 1, the sliding rod 42 moves, causing the connecting block 72 and the long rod 71 to move. The movement of the long rod 71 tightens the elastic rope 73, which then pulls the locking block 66 to move. After the cover plate 2 is completely placed onto the flange 1, the locking block 66 disengages from the slot 621. At this time, the limiting spring 64 pushes the fixing ring 63 and the limiting rod 62 to move, causing the limiting rod 62 to insert into the groove 14, thereby reducing the possibility of the cover plate 2 disengaging from the flange 1. During the process of the tension spring 54 pushing the sliding rod 42 and the sealing plate 41 to move towards the end closer to the first piston 43... During the process, the sliding rod 42 moves, causing the connecting block 72 and the long rod 71 to move, thereby making the first rack 84 mesh with the gear 85 and causing the gear 85 to rotate. The rotation of the gear 85 causes the second rack 86 and the pulling rod 81 to move. The movement of the pulling rod 81 causes the pulling rope 82 to tighten. Then the pulling rope 82 drives the limiting rod 62 to move, causing the limiting rod 62 to disengage from the groove 14. At this time, the clamping spring 67 pushes the locking block 66, causing the locking block 66 to insert into the locking groove 621, thereby fixing the limiting rod 62 so that the cover plate 2 can be disassembled after the pouring is completed, and the cover plate 2 can be reused.

[0047] The implementation principle of the pre-sealed structure and construction method of the settlement-post-cast strip 11 in this application embodiment is as follows: the cover plate 2 is placed on the flange 1, the insertion pipe 3 is sealed by two sets of sealing mechanisms 4, and the cover plate 2 is fixed by two sets of limiting mechanisms 6. After the main building has settled and stabilized, the casting pipe 12 is inserted into the insertion pipe 3, and the sealing mechanism 4 is released from the sealing of the insertion pipe 3, so that the settlement-post-cast strip 11 can be cast.

[0048] The construction method for the pre-closed structure of the settlement-post-settlement casting strip 11 includes the following steps: S1. After settlement, pour flanges 1 on both sides of the pouring strip 11; S2. Place multiple cover plates 2 on the flange 1 in sequence to make the adjacent cover plates 2 tightly connected. S3. After the main building has settled and stabilized, insert the 12 pouring pipes into the insertion pipe 3 and pour concrete into the settlement strip 11.
