Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a leak-proof device for a casing of an exterior wall. Background Technology

[0002] During building construction, pre-embedded sleeves in the exterior walls are used for the subsequent installation of water and electricity pipes. These sleeves leave holes after installation, allowing water from outside the wall to easily seep into the interior. Especially during the rainy season when rainfall is heavy, if basement water leaks through these sleeve holes, it can cause significant economic losses.

[0003] Currently, before pipes or cables are installed on external wall sleeves, the traditional sealing methods are generally sealing with sealing mud or blind flange sealing. However, these sealing methods are easily damaged by rainwater accumulated on the external wall, reducing the tightness of the seal and causing water to leak into the indoor environment, thereby reducing the quality of building construction. Summary of the Invention

[0004] In order to improve the problem of rainwater accumulation on exterior walls causing damage and reducing the tightness of the seal, leading to water leakage into the indoor environment and thus reducing the quality of building construction, this application provides a leak-proof device for exterior wall sleeves.

[0005] The technical solution for the building exterior wall sleeve anti-leakage device provided in this application is as follows:

[0006] A leak-proof device for a building exterior wall sleeve includes a sealing component, a connecting component, an abutting component, and a leak-proof component. The sealing component includes a sealing plate that abuts against the end of the sleeve located outside the exterior wall, and the sealing plate is used to seal the sleeve. The abutting component includes an abutting plate that abuts against the end of the sleeve located inside the exterior wall. The connecting component is used to connect the sealing plate and the abutting plate. When the abutting plate abuts against the end of the sleeve located inside the exterior wall, the relative position between the connecting component and the sleeve is stable. The leak-proof component is disposed inside the sealing plate. After the water and electricity pipelines are installed, a gap is formed between the outer wall of the water and electricity pipelines and the inner wall of the sleeve. The leak-proof component is used to seal the gap.

[0007] By adopting the above technical solution, the abutment plate is first inserted into the sleeve, and the sealing plate is made to fit against the end face of the sleeve located outside the outer wall. Then, the abutment plate is moved synchronously through the connecting component, and the abutment plate abuts against the end face of the sleeve away from the sealing plate. The contact plate abuts against the end face of the sleeve, stabilizing the connecting components relative to the sleeve. Simultaneously, it drives the sealing plate to move towards one side of the exterior wall, resulting in a tighter fit between the sealing plate and the end face of the sleeve, sealing the sleeve and reducing the seepage of water from outside the exterior wall into the interior wall. During subsequent installation of water and electricity pipes, gaps are typically formed between the outer wall of the pipes and the inner wall of the sleeve for ease of installation. These gaps are filled with fine stone mortar for sealing and simultaneously securing the pipes. The gaps outside the exterior wall are further sealed using the anti-seepage component, reducing the possibility of water seeping into the wall and indoor environment. This device effectively improves the sealing of openings, reducing the seepage of rainwater or accumulated water into the exterior wall and indoor environment, thus contributing to improved construction quality.

[0008] Preferably, the connecting assembly includes a connecting rotating rod and a connecting sleeve rod. The connecting rotating rod is coaxially rotatably connected to the connecting sleeve rod. The sealing plate is sleeved on one end of the connecting sleeve rod. The abutting plate is located at the end of the connecting sleeve rod away from the sealing plate. The sealing plate slides relative to the connecting sleeve rod along the axial direction of the connecting sleeve rod. The connecting rotating rod has a rotating part at the end outside the outer wall. When the rotating part rotates, it synchronously drives the sealing plate to slide along the connecting sleeve rod and the abutting plate to abut against the end face of the sleeve inside the outer wall.

[0009] By adopting the above technical solution, the rotation of the rotating part can synchronously drive the sealing plate to slide along the connecting sleeve rod, so that the sealing plate and the end face of the sleeve can be more tightly abutted, sealing the cavity and reducing water seepage; at the same time, the abutting plate abuts against the end face of the sleeve located inside the outer wall. The abutting of the abutting plate makes the overall position of the connecting component relatively stable relative to the sleeve, which is more conducive to the sealing plate to achieve a tight seal on the sleeve and is easy to operate.

[0010] Preferably, the sealing plate has a connecting hole for the connecting sleeve rod to pass through, and the connecting hole wall has a plurality of mating blocks around its perimeter. The outer wall of the connecting sleeve rod has a mating groove for placing the mating blocks, and the mating groove corresponds one-to-one with the mating block.

[0011] By adopting the above technical solution, the mating block is located in the mating groove, so that the sealing plate and the connecting sleeve are connected, and the sealing plate can only be displaced along the axial direction of the connecting sleeve.

[0012] Preferably, one end of the connecting sleeve extends into the rotating part, and the rotating part is provided with a plurality of inclined blocks on the side facing the outer wall. The thickness of the inclined blocks gradually increases along the circumference of the connecting sleeve, and the inclined blocks are made of elastic material. The inclined blocks abut against the mating blocks.

[0013] By adopting the above technical solution, before installation, the thinner part of the individual inclined block is aligned with the groove wall of the mating block and the mating slot. The connecting component is then inserted into the sleeve, and the sealing plate is aligned with one end face of the sleeve. After adjusting the position, the rotating part is rotated, causing the inclined block to rotate synchronously. As the thickness of the inclined block gradually increases, during rotation, the inclined block continuously presses against the mating block and drives the mating block to move towards the side closer to the outer wall. This, in turn, causes the sealing plate to move towards the side of the outer wall, resulting in a tighter contact between the sealing plate and the end face of the sleeve, achieving a seal.

[0014] Preferably, the abutting assembly includes a fixing plate and an abutting plate. The fixing plate is located at the end of the connecting rod away from the sealing plate. The fixing plate is provided with a fixing gear. The abutting plate is slidably connected to the end face of the connecting sleeve rod located inside the outer wall. The abutting plate is provided with a movable gear row, which meshes with the fixing gear.

[0015] By adopting the above technical solution, the connecting component is inserted into the sleeve, and the sealing plate is attached to one end face of the sleeve. After adjusting the position, the rotating part is rotated, which drives the connecting rod to rotate. The connecting rod drives the fixed gear to rotate, and the fixed gear drives the moving gear row to move. The moving gear row drives the abutting plate to move to abut against the end face of the sleeve, so that the connecting rod and the connecting sleeve rod are stable relative to the sleeve.

[0016] Preferably, the outer wall of the connecting sleeve is rotatably connected to a transmission gear, the transmission gear meshes with a fixed gear, and at least two abutting plates are provided, that is, at least two movable tooth rows are provided, the at least two movable tooth rows are symmetrical to both sides of the fixed gear, and at least two movable tooth rows mesh with the transmission gear one-to-one, driving the fixed gear to rotate, and synchronously driving the two abutting plates to move in opposite directions.

[0017] By adopting the above technical solution, the fixed gear drives two transmission gears to rotate synchronously, and the transmission gears drive at least two moving gear rows and the abutting plate to move synchronously, so that the abutting plate abuts against the end face of the sleeve away from the sealing plate.

[0018] Preferably, the seepage-proof component includes an abutment ring plate, a sealing ring, and a clamping plate. The abutment ring plate is sleeved on the outer wall of the water and electricity pipeline. The sealing ring is connected to the side of the abutment ring plate facing the outer wall and is located in the gap. The sealing ring is made of an elastic material. The clamping plate is located on the side of the sealing ring away from the abutment ring plate and is located in the gap. The component also includes a driving assembly for driving the clamping plate to move so that the clamping plate cooperates with the abutment ring plate to clamp the sealing ring.

[0019] By adopting the above technical solution, after the sealing plate, connecting components, and abutting components are removed from the sleeve, the water and electricity pipelines are installed inside the sleeve. Simultaneously, the water and electricity pipelines pass through the clamping plate, sealing ring, and abutting ring plate. The driving component drives the clamping plate and abutting ring plate to clamp the sealing ring, causing the sealing ring to deform and expand, abutting against the inner wall of the sleeve and the outer wall of the water and electricity loop, thus sealing the gaps and reducing the possibility of water seepage into the exterior wall.

[0020] Preferably, the driving assembly includes a guide tube, a clamping screw, and a movable clamping rod. The guide tube is located on the side of the abutment ring plate facing the outer wall. The clamping plate and the sealing ring are movably sleeved on the guide tube. An annular groove is formed in the abutment ring plate. The clamping screw is rotatably connected to the inside of the guide tube and one end extends to the outside of the guide tube. The movable clamping rod is located on the side of the clamping plate away from the sealing ring and is threaded onto the clamping screw. The end of the clamping screw away from the guide tube extends into the annular groove. An internal gear ring is rotatably connected to the inner wall of the annular groove. A driving gear meshes with the inner wall of the internal gear ring, and the driving gear is fixedly connected to the clamping screw.

[0021] Preferably, the clamping screw has a drive handle at one end extending outside the abutting ring plate, and the abutting ring plate has an annular cover plate on the side away from the sealing ring. The annular cover plate is sleeved on the clamping screw, and the annular cover plate is adapted to the contour of the annular groove.

[0022] By adopting the above technical solution, the drive handle is driven to rotate the clamping screw, causing the clamping plate to move closer to the abutment ring plate and cooperate with the abutment ring plate to clamp and press the sealing ring, causing the sealing ring to deform and expand.

[0023] Preferably, it further includes a limiting component, which includes a limiting rod and a limiting spring rod. The limiting rod is disposed on the connecting sleeve rod, and the limiting spring rod is disposed at the end of the limiting rod away from the connecting sleeve. The end of the limiting rod is provided with a spring, and the spring and one end of the limiting rod are located inside the limiting spring rod. The drive handle is provided with an anti-rotation hole, and the end of the limiting spring rod away from the limiting rod extends into the anti-rotation hole. The limiting spring rod limits the rotation of the drive handle.

[0024] By adopting the above technical solution

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up the abutment component, connecting component, and sealing component, the connecting component is inserted into the sleeve, and the sealing plate is in contact with one end face of the sleeve. After adjusting the position, the rotating part is rotated, which drives the connecting rod to rotate. The connecting rod drives the fixed gear to rotate, which drives two transmission gears to rotate synchronously. The transmission gears drive the moving gear rack and the abutment plate to move synchronously, so that the abutment plate abuts against the end face of the sleeve opposite to the sealing plate; the abutment plate abuts against the end face of the sleeve, making the connecting rod and the connecting sleeve rod stable relative to the sleeve. At the same time, the rotating part drives the inclined block to rotate synchronously. As the thickness of the inclined block gradually increases, during the rotation, the inclined block continuously presses against the mating block and drives the mating block to move towards the side closer to the outer wall, thereby driving the sealing plate to move towards the side of the outer wall, making the abutment between the sealing plate and the end face of the sleeve tighter, achieving a seal.

[0027] 2. By setting up the anti-seepage component, the drive handle drives the clamping screw to rotate, causing the clamping plate to move closer to the abutment ring plate and cooperate with the abutment ring plate to clamp and press the sealing ring, causing the sealing ring to deform and expand, and abut against the inner wall of the sleeve and the outer wall of the water and electricity loop, sealing the gap and reducing the possibility of water seepage into the exterior wall.

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a leak-proof device for building exterior wall sleeves, such as... Figure 1 As shown, the device includes a sealing component 4, an abutment component 5, a connecting component 6, and a seepage-proof component 7 installed on the outer wall 1 and the sleeve 2 inside the outer wall 1. The sealing component 4 is used to seal the end of the sleeve 2 located outside the outer wall. The abutment component 5 is used to abut the end of the sleeve 2 located inside the outer wall. The connecting component 6 is used to connect the sealing component 4 and the abutment component 5. The seepage-proof component 7 is used to seal the gap between the installed water and electricity pipes 3 and the sleeve 2, reducing the seepage of water accumulated outside the outer wall into the wall and then into the indoor space, thereby improving the seepage-proof performance of the outer wall.

[0039] like Figure 1 , 2 As shown in Figure 3, the sealing assembly 4 includes a sealing plate 41, which is made of an elastic material. A connection hole 411 is provided in the sealing plate 41, and multiple mating blocks 42 are fixedly connected to the circumference of the hole wall of the connection hole 411.

[0040] like Figure 2As shown, the connecting assembly 6 includes a connecting rotating rod 61 and a connecting sleeve rod 62. The connecting rotating rod 61 is coaxially rotatably connected to the connecting sleeve rod 62. The outer wall of the connecting sleeve rod 62 has a mating groove 621 for accommodating a mating block 42. There are three mating blocks 42, meaning there are also three mating grooves 621, so that the sealing plate 41 is fitted over the connecting sleeve rod 62, and the sealing plate 41 can only move along the axial direction of the connecting sleeve rod 62. A rotating part 611 is fixedly connected to one end of the connecting rotating rod 61 located outside the outer wall 1, and one end of the connecting sleeve rod 62 extends into the rotating part 611. Multiple inclined blocks 612 are fixedly connected to the side of the rotating part 611 facing the outer wall 1. The thickness of the inclined blocks 612 gradually increases along the circumferential direction of the connecting rotating rod 61, and the inclined blocks 612 are made of elastic material.

[0041] like Figure 4 , 5 As shown in Figure 6, the abutment assembly 5 includes a fixed plate 51 and an abutment clamping plate 53. The fixed plate 51 is coaxially fixedly connected to the end of the connecting rotating rod 61 away from the sealing plate 41. A fixed gear 511 is coaxially fixedly connected to the fixed plate 51 around its circumference. A transmission gear 52 is rotatably connected to the outer wall of the connecting sleeve rod 62. There are two transmission gears 52, and both of them mesh with the fixed gear 511. The abutment clamping plate 53 is slidably connected to the outer end face of the connecting sleeve rod 62. A movable gear row 54 is fixedly connected to the abutment clamping plate 53, and the movable gear row 54 meshes with the transmission gear 52. There are two abutment clamping plates 53, which means there are two movable gear rows 54. The two movable gear rows 54 are symmetrical about both sides of the fixed gear 511 and both mesh with the corresponding transmission gear 52. Driving the fixed gear 511 to rotate synchronously drives the two abutment clamping plates 53 to move in opposite directions.

[0042] Before installation, the thinner part of the individual inclined block 612 is aligned with the groove wall of the mating block 42 and the mating groove 621. The connecting assembly 6 is inserted into the sleeve 2, and the sealing plate 41 is aligned with one end face of the sleeve 2. After adjusting the position, the rotating part 611 is rotated, which drives the connecting rod 61 to rotate. The connecting rod 61 drives the fixed gear 511 to rotate, which drives the two transmission gears 52 to rotate synchronously. The transmission gears 52 drive the moving gear row 54 and the abutting plate 53 to move synchronously, so that the abutting plate 53 abuts against the end face of the sleeve 2 away from the sealing plate 41. The abutting plate 53 abuts against the end face of the sleeve 2, making the connecting rod 61 and the connecting sleeve rod 62 stable relative to the sleeve 2. At the same time, the rotating part 611 drives the inclined block 612 to rotate synchronously. As the thickness of the inclined block 612 gradually increases, during the rotation process, the inclined block 612 continuously presses against the mating block 42 and drives the mating block 42 to move towards the side closer to the outer wall 1, thereby driving the sealing plate 41 to move towards the side of the outer wall 1, so that the sealing plate 41 and the end face of the sleeve 2 are more tightly abutted, thus achieving a seal.

[0043] like Figure 4 , 7 As shown in Figure 8, during the subsequent construction of the water and electricity pipes 3, a gap is usually formed between the outer wall of the water and electricity pipes 3 and the inner wall of the sleeve 2 for ease of installation. The gap is filled with fine stone mortar for sealing and at the same time, the water and electricity pipes 3 are fixed. The gap outside the outer wall 1 is further sealed by the anti-seepage component 7 to reduce the possibility of water seeping into the wall and indoor environment through the gap.

[0044] like Figure 3 , 4 As shown in Figure 7, the seepage prevention component 7 includes an abutment ring plate 71, a sealing ring 72, and a clamping plate 73. The abutment ring plate 71 is sleeved on the outer wall of the water and electricity pipeline 3, and is fixed to the outer wall of the outer wall 1 by screws. The sealing ring 72 is connected to the side of the abutment ring plate 71 facing the outer wall 1 and is located within the gap. The sealing ring 72 is made of elastic material. The clamping plate 73 is located on the side of the sealing ring 72 away from the abutment ring plate 71 and is located within the gap. A drive assembly 8 is also included for driving the clamping plate 73 to move, so that the clamping plate 73 cooperates with the abutment ring plate 71 to clamp the sealing ring 72.

[0045] like Figure 3 , 5 As shown in Figure 7, the water and electricity pipes 3 pass through the clamping plate 73 and the sealing ring 72. The drive assembly 8 includes a guide tube 81, a clamping screw 82, and a movable clamping rod 83. The guide tube 81 is fixedly connected to the side of the abutting ring plate 71 facing the outer wall 1. The clamping plate 73 and the sealing ring 72 are movably sleeved on the two guide tubes 81. An annular groove 711 is opened in the abutting ring plate 71. The clamping screw 82 is rotatably connected to the inside of the guide tube 81 and one end extends to the outside of the guide tube 81. The movable clamping rod 83 is fixedly connected to the side of the clamping plate 73 away from the sealing ring 72, and the movable clamping rod 83 is threaded onto the clamping screw 82. The end of the clamping screw 82 away from the guide tube 81 extends into the annular groove 711. An internal gear ring 712 is rotatably connected to the inner wall of the annular groove 711. A drive gear 821 meshes with the inner wall of the internal gear ring 712, and the drive gear 821 is fixedly connected to the clamping screw 82. In this embodiment, there are two sets of drive components 8, which are symmetrically arranged on the upper and lower sides of the water and electricity pipeline 3 along its diameter. One end of the clamping screw 82 located at the top extends to the outside of the abutting ring plate 71 and is fixedly connected to a drive handle 84. An annular cover plate is fixedly connected to the side of the abutting ring plate 71 away from the sealing ring 72. The annular cover plate is sleeved on the clamping screw 82, and the annular cover plate is adapted to the contour of the annular groove 711.

[0046] After the sealing plate 41, connecting component 6, and abutting component 5 are removed from the sleeve 2, the water and electricity pipe 3 is installed inside the sleeve 2. Simultaneously, the water and electricity pipe 3 passes through the clamping plate 73, sealing ring 72, and abutting ring plate 71. Then, the abutting ring plate 71 is fixedly connected to the outer wall 1 with screws. The drive handle 84 is driven to rotate the clamping screw 82, causing the clamping plate 73 to move closer to the abutting ring plate 71 and cooperate with the abutting ring plate 71 to clamp and press the sealing ring 72. This causes the sealing ring 72 to deform and expand, abutting against the inner wall of the sleeve 2 and the outer wall of the water and electricity loop, sealing the gaps and reducing the possibility of water seepage into the outer wall 1.

[0047] like Figure 3 and 5 As shown, to improve the ease of use of the anti-seepage device, the anti-seepage component 7 is installed inside the sealing plate 41. In the initial state, the anti-seepage component 7 and the sealing plate 41 are connected and relatively fixed. When the sealing component 4, the abutment component 5, and the connecting component 6 are moved away from the sleeve 2, a limiting component 9 is also included to facilitate the separation of the anti-seepage component 7 and the driving component 8 from the sealing plate 41.

[0048] like Figure 5 As shown, the limiting component 9 includes a limiting rod 91 and a limiting spring rod 93. The limiting rod 91 is slidably connected to the sleeve rod, and the limiting spring rod 93 is sleeved on the end of the limiting rod 91 away from the connecting sleeve 2. A spring 92 is provided at the end of the limiting rod 91, and the spring 92 and one end of the limiting rod 91 are located inside the limiting spring rod 93. An anti-rotation hole 841 is provided on the drive handle 84, and the end of the limiting spring rod 93 away from the limiting rod 91 extends into the anti-rotation hole 841. The limiting spring rod 93 stops and limits the rotation of the drive handle 84, thus maintaining a relatively static and stable state between the seepage-proof component 7 and the sealing plate 41. When the connecting sleeve rod 62 and the sealing plate 41 move away from the sleeve 2, the limiting rod 91 and the limiting spring rod 93 move synchronously, causing the seepage-proof component 7 to separate from the sealing plate 41, facilitating subsequent sealing of the gaps.

[0049] The implementation principle of the anti-leakage device for building exterior wall sleeves in this application embodiment is as follows:

[0050] When the sealing plate 41 is used to seal the opening of the sleeve 2, the rotating part 611 drives the inclined block 612 to rotate, and the inclined block 612 abuts against the mating block 42, so that the sealing plate 41 seals the sleeve 2; when the water and electricity pipeline 3 is installed, the rotating block is rotated in the opposite direction, so that the rotating block drives the connecting rod 61 to rotate, thereby driving the abutting plate 53 to retract and release the clamping between it and the end face of the sleeve 2. Simultaneously, the inclined block 612 rotates with the rotating part 611, releasing the clamping of the mating block 42, so that the sealing plate 41 and the end face of the sleeve 2 are in a state of separation. Then, the connecting assembly 6 and the sealing plate 41 are moved away from the sleeve 2. The connecting sleeve rod 62 drives the limiting rod 91 and the limiting spring rod 93 to move away simultaneously. At the same time, the water and electricity pipe 3 is inserted into the sleeve 2 and passes through the clamping plate 73 and the sealing ring plate. Then, by driving the driving handle 84, the clamping screw 82 is rotated, so that the clamping plate 73 moves closer to the abutting ring plate 71 and cooperates with the abutting ring plate 71 to clamp and press the sealing ring 72, so that the sealing ring 72 itself deforms and expands, abutting against the inner wall of the sleeve 2 and the outer wall of the water and electricity pipe 3, thus sealing the gap.

[0051] 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.
