Abstract
Description
Technical Field
[0001] This invention relates to the field of waterproof building technology, specifically to a sealing structure for concrete bonding in waterproof building construction. Background Technology
[0002] With the development of prefabricated buildings and super high-rise concrete structures, waterproofing and sealing technology has become a core element in ensuring the durability and safety of buildings. Expansion joints are a general term for settlement joints, expansion joints, and seismic joints. Buildings often deform or even break due to external factors, and expansion joints are reserved to address this situation and play an auxiliary role. In concrete-coated sealing structures, water-stop steel plates and water-stop strips form a continuous waterproof barrier through close bonding with the concrete. This structure can effectively prevent water penetration and ensure the waterproof performance of the concrete structure. However, existing sealing structures often cannot effectively prevent rainwater penetration when facing complex climatic environments and rainwater erosion. Rainwater may enter the concrete through gaps in the sealing structure, causing the concrete structure to become damp and corroded, thereby affecting the structural strength and stability of the building.
[0003] In existing technologies, such as the large-span continuous basement expansion joint waterproofing structure disclosed in CN117488880A, as the sealing column moves, the stored force of the elastic element gradually decreases, and the top pressure on the pressure column also gradually decreases. Since some pressure columns stop moving after moving their corresponding effective displacement, they no longer share the squeezing force of the hydraulic oil, allowing other pressure columns that have not moved to their corresponding effective displacement to bear the top pressure, thereby ensuring that at least one pressure column can maintain a constant top pressure on the waterproof strip.
[0004] However, during prolonged use, the waterstop can easily detach from the aluminum alloy base due to the downward force of internal water accumulation. In heavy rain, some water can seep into the interior of the prefabricated building. Traditional waterproofing mechanisms cannot effectively guide and drain rainwater, causing it to accumulate on the surface of the sealed structure. This prolonged accumulation not only puts excessive pressure on the sealed structure but can also cause localized damage. Furthermore, when the buildings on both sides of the expansion joint move closer or further apart, they can stretch the waterproofing device, affecting its normal operation and significantly shortening the lifespan of the sealed structure.
[0005] Therefore, this invention proposes a sealing structure for waterproof building concrete joints to solve the problems of poor sealing performance and easy damage affecting service life of existing waterproofing mechanisms for expansion joints. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Example 1, please refer to Figure 1-11 This invention provides a technical solution: a waterproof building sealing structure for concrete bonding, comprising a concrete structure 1 and an expansion joint 10. The concrete structures 1 are respectively disposed on both sides of the expansion joint 10, and a waterproof strip 3 is disposed between the concrete structures 1. A waterproof mechanism is disposed at the upper end of the concrete structure 1, the waterproof mechanism comprising a base 1 2, a base 21, and a fire-resistant panel 22. A fastening mechanism is movably installed at the upper end of the waterproof mechanism, the fastening mechanism comprising a sealing steel plate 4, an elastic abutment plate 42, and a locking component 43. A reserved groove is provided between the base 1 2 and the base 21. 90. A retaining mechanism is provided on the inner side of the reserved groove 90. The retaining mechanism includes a retaining part and a telescopic part. The waterproof strip 3 is composed of a horizontal part and a curved part. The horizontal part is sandwiched between the pressure plate and the waterproof mechanism. The curved part is located inside the reserved groove 90. A drainage strip 32 is fixedly installed on the upper surface of the curved part for guiding and clearing the infiltrated rainwater, preventing rainwater accumulation from causing the middle end of the waterproof strip 3 to fall due to gravity and affecting its service life, ensuring that the infiltrated rainwater is evenly distributed on the waterproof strip 3, and preventing rainwater accumulation from causing the waterproof strip 3 to tear at the connection between the expansion joint 10.
[0033] In this embodiment, the structure of the waterproof strip 3 is optimized to adapt to the changes in the expansion joint 10. Combined with the waterproofing mechanism, and through the cooperation of the pressure plate, base plate, waterproofing components, and connectors, it not only enhances the installation structure of the waterproof strip 3 but also achieves multiple waterproofing measures when the expansion joint 10 changes. The cooperation of the abutment mechanism with the waterproof strip 3 provides limiting support when the expansion joint 10 changes and also assists in abutting the bottom of the waterproof strip 3, improving its protective performance, extending its service life, and further preventing damage and tearing of the waterproof strip 3 structure during the expansion or contraction of the expansion joint 10. It is highly practical, and the cooperation between the fastening mechanism and the waterproofing mechanism facilitates convenient disassembly and replacement of each component. The waterproof strip 3 is designed to guide and unblock water, preventing rainwater accumulation and gathering, preventing its middle section from falling due to gravity and affecting its service life, and preventing tearing at the connection with the expansion joint 10. At the same time, its integrated molding structure optimizes the matching degree with each component, ensuring stable installation without deviation when the expansion joint 10 changes.
[0034] Example 2, see attached document Figure 1-11 Based on Embodiment 1, to achieve multiple waterproofing between expansion joints 10: the waterproofing mechanism further includes a pressure plate, a base plate, a waterproofing component, and a connecting component. The pressure plate is composed of a first waterproof pressure plate 5 and a second waterproof pressure plate 51. The first waterproof pressure plate 5 and the second waterproof pressure plate 51 are fixedly connected to the upper inner walls of the first base 2 and the second base 21 respectively by bolts. A sealing groove 50 is provided on the upper inner wall of the first waterproof pressure plate 5 and the second waterproof pressure plate 51. The base plate is composed of a first fixed base plate 6 and a second fixed base plate 61. A rubber sealing strip 60 is fixedly installed on the lower inner wall of the first fixed base plate 6 and the second fixed base plate 61. The outer surface of the rubber sealing strip 60 is movably engaged with the inner wall of the sealing groove 50. The waterproofing component is composed of a first shaped waterproof strip 7 and a second shaped waterproof strip 71. The first shaped waterproof strip 7 and the second shaped waterproof strip 71 are connected to each other. The second waterproof strip 71 is sandwiched between the inner side of the sealing steel plate 4 and the outer side of the fixed base plate 6. The fixed base plate 6 and the second fixed base plate 61 are fixedly connected to the upper inner wall of the base 2 and the base 21 respectively by bolts. The lower surface of the waterproof pressure plate 5 and the second waterproof pressure plate 51 is provided with a slot 500. A convex strip 31 is fixedly installed on the horizontal part. The lower surface of the convex strip 31 is adapted to fit into the upper surface of the base 2 and the base 21, and the upper surface of the convex strip 31 is adapted to fit into the inner wall of the slot 500. The waterproof strip 3 is integrally formed with the convex strip 31 through the horizontal part, the curved part and the convex strip 31. Through the optimization of the overall structure of the waterproof strip 3, the matching degree between the connection with each component can be improved, the sealing performance can be enhanced, and the waterproof strip 3 can be installed stably when the expansion joint 10 changes, avoiding displacement.
[0035] In this embodiment, before assembling the sealing steel plate 4, the waterproof strip 3 is laid between the base 1 2 and the base 2 21. The curved part of the waterproof strip 3 is positioned between the reserved grooves 90, maintaining the reserved length of the curved part, and the horizontal part is laid on the surface of the base 1 2. At this time, the waterproof pressure plate 5 is pressed onto the horizontal surface of the waterproof strip 3, and the slot 500 and the convex strip 31 are matched and engaged, which not only ensures the pressing of the waterproof strip 3, but also avoids the displacement of the waterproof strip 3 when the deformation joint 10 changes. The irregularly shaped waterproof strip 7 is installed on the surface of the fixed base plate 6. Subsequently, when installing the sealing steel plate 4, the bolt assembly penetrates the inner wall of the fixed base plate 6 and the waterproof pressure plate 5, and extends into the interior of the base 1 2. The installation of the waterproof mechanism, through optimized structural design, reduces the risk of rainwater infiltration and further extends its service life. The waterproof mechanism consists of a pressure plate, a base plate, waterproof components, and connectors. The waterproof strip 3 is laid between base 1 2 and base 2 21. The horizontal part is pressed by the pressure plate, and the curved part is located in the reserved groove 90. The drainage strip 32 on it guides and unblocks the infiltrated rainwater, preventing rainwater accumulation and gathering, preventing the middle of the waterproof strip from falling due to gravity and affecting its service life, and preventing the waterproof strip from tearing at the connection with the expansion joint. The rubber sealing strip 60 on the base plate is embedded with the sealing groove 50 on the pressure plate. The waterproof component is sandwiched between the sealing steel plate 4 and the base plate, forming multiple waterproof barriers to effectively prevent rainwater from infiltrating.
[0036] Example 3, refer to Appendix Figure 1-11 Based on Embodiment 2, to achieve stability of the sealing steel plate 4 after installation: the connecting component includes a connecting plate 8 and a C-shaped limiting groove 81. The C-shaped limiting groove 81 is located between the sealing steel plate 4 and the waterproof pressure plate 5. The C-shaped limiting groove 81 is fixedly installed on one end of the inner side of the connecting plate 8, and a telescopic plate 82 is fixedly connected between the two sets of C-shaped limiting grooves 81. The two ends of the sealing steel plate 4 are integrally formed and connected with guide flanges 41. An elastic abutment 42 is fixedly installed on the inner side of the center of the sealing steel plate 4. Two sets of elastic abutments 42 are provided and are mirror-distributed about the longitudinal central axis of the sealing steel plate 4. An insert 421 is fixedly installed on the lower end of the elastic abutment 42. A T-shaped slot is opened on the inner wall of the upper end of the C-shaped limiting groove 81. The inner surface of the T-shaped slot is movably engaged with the outer surface of the insert 421.
[0037] In this embodiment, after the waterproof mechanism is installed, the sealing steel plate 4 is placed on the top surface. The initial positioning of the sealing steel plate 4 is ensured by the matching of the insert 421 with the T-shaped slot at the upper end of the C-shaped limiting groove 81. When the expansion joint 10 changes, the elastic action of the elastic abutment 42 is coordinated, and the two sets of elastic abutment 42 move inward and outward respectively.
[0038] Example 4, see attached document Figure 1-11Based on Embodiment 3, in order to enable the locking component 43 to adapt to horizontal changes in the expansion joint 10, the locking component 43 includes a connector and a sliding component. The connector includes a rotating sleeve 431, a force-bearing nut 432, and a limiting ring 433. The rotating sleeve 431 and the force-bearing nut 432 are integrally formed. The outer surface of the limiting ring 433 is threadedly connected to the inner surface of the rotating sleeve 431. The limiting ring 433 is fixedly installed on the outer surface of the rotating sleeve 431. The central inner wall of the sealing steel plate 4 is... A rotating groove 40 is provided, and the inner surface of the rotating groove 40 is rotatably connected to the outer surface of the limiting rotating ring 433; the sliding component includes a locking collar 435, a fixed arm 436, and a movable ball 437. The inner surface of the locking collar 435 is threadedly connected to the lower outer surface of the fastening screw 434. The fixed arm 436 is fixedly installed on both outer surfaces of the locking collar 435, and the movable ball 437 is fixedly installed on the other end of the fixed arm 436. The outer surface of the movable ball 437 is movably connected to the inner surface of the C-shaped limiting groove 81.
[0039] In this embodiment, the fastening mechanism, through the cooperation of the connecting part and the sliding part of the locking component 43, achieves stable fastening and flexible adjustment of the sealing steel plate 4 on the expansion joint 10. The supporting part and the telescopic part of the abutment mechanism work together to ensure structural stability and extend the service life by protecting the connecting spring 94 through the protective sleeve 95. The overall structure comprehensively improves the waterproof sealing effect, structural stability and service life. Specifically, when the expansion joint 10 is affected by external factors, refer to Figure 7 As shown, the connecting plate 8 and the C-shaped limiting groove 81 approach each other. At this time, the C-shaped limiting groove 81 moves the position of the inner movable ball 437. At this time, the limiting rotating ring 433 moves on the side wall of the rotating groove 40 to maintain the overall stability of the locking assembly 43. At this time, the horizontal sliding part changes angle to adapt to deformation joints of different widths without affecting the stability of the sealing steel plate 4 installation.
[0040] Example 5, see attached document Figure 1-11Based on Embodiment 4, in order to support the bottom of the curved section of the waterproof strip 3 and prevent excessive rainwater penetration that could cause the middle of the waterproof strip 3 to sag under gravity and become damaged: the supporting component includes a movable plate 9, one end of which is rotatably connected to the side wall of the reserved groove 90. The two sets of movable plates 9 are mirror-distributed, and anti-slip ridges are fixedly added to the outer surface of the movable plate 9. The telescopic component includes a telescopic sleeve 91, a horizontal plate 92, and a connecting spring 94. One end of the telescopic sleeve 91 is fixedly connected to the inner surface of the base 1 2 and the base 2 21, respectively. The outer surface of the horizontal plate 92 is slidably connected to the inner surface of the telescopic sleeve 91. The connecting spring 94 is located between the two sets of horizontal plates 92 and is fixedly connected to their surfaces. An elastic block 93 is fixedly connected to one end of the horizontal plate 92 away from the connecting spring 94. The other end of the elastic block 93 is fixedly connected to the inner surface of the telescopic sleeve 91. A slider 921 is fixedly installed on the outer surface of the horizontal plate 92 away from the connecting spring 94. The outer surface of the slider 921 is fixedly connected to the inner surface of the movable plate 9. A protective sleeve 95 is provided on the outside of the connecting spring 94. The two ends of the protective sleeve 95 are fixedly connected to one end of the two sets of horizontal plates 92, respectively. The protective sleeve 95 not only satisfies the connection of the two sets of horizontal plates 92, but also protects the connecting spring 94, preventing corrosion of the connecting spring 94 in the event of water leakage, and further extending its service life.
[0041] In this embodiment, when the expansion joint 10 changes horizontally, the base 1 2 and the base 2 21 push inward or pull outward respectively. At this time, the two sets of horizontal plates 92 move relative to each other, and the connecting spring 94 and the protective sleeve 95 deform and expand. During the movement of the horizontal plate 92, the slider 921 drives one end of the movable plate 9 on both sides to move, while the other end rotates axially along the side wall of the base 1 2 and the base 2 21. This satisfies the requirement of stable connection when the expansion joint 10 changes horizontally, and also ensures auxiliary support for the bent part of the waterproof strip 3, avoiding damage to the waterproof strip 3 due to gravity.
[0042] The working principle and usage process of this invention are as follows: In actual use, firstly, before assembling the sealing steel plate 4, the waterproof strip 3 is laid between base 1 2 and base 2 21, so that the curved part of the waterproof strip 3 is positioned between the reserved grooves 90, maintaining the reserved length of the curved part, and the horizontal part is laid on the surface of base 1 2 and base 2 21 respectively; then, the waterproof pressure plate 1 5 and waterproof pressure plate 2 51 are pressed onto the horizontal part surface of the waterproof strip 3 respectively, so that the grooves 500 on the lower surface of the waterproof pressure plate 1 5 and waterproof pressure plate 2 51 are in contact with the waterproof strip 3. The convex strip 31 on the horizontal part of the water hose 3 is fitted and snapped together to ensure the pressing of the waterproof hose 3 and prevent its displacement. The irregularly shaped waterproof hose 7 and the irregularly shaped waterproof hose 71 are respectively installed on the surface of the fixed base plate 6 and the fixed base plate 61. Then, the bolt assembly passes through the inner wall of the base plate and the waterproof component and extends into the interior of the base 2 and the base 21 to complete the installation of the waterproof mechanism. After the waterproof mechanism is installed, the sealing steel plate 4 is placed on the top surface. The sealing steel plate is secured by the insert 421 at the lower end and the C-shaped limiting groove 81. The upper T-shaped groove adapts to achieve the initial positioning of the sealing steel plate 4; when the expansion joint 10 changes due to external factors, the connecting plate 8 and the C-shaped limiting groove 81 move closer to each other, and the C-shaped limiting groove 81 moves the inner movable ball 437. At this time, the limiting rotating ring 433 moves on the side wall of the sealing steel plate 4 to maintain the overall stable positioning of the locking assembly. At the same time, the sliding part changes angle to adapt to expansion joints of different widths, ensuring the stability of the installation of the sealing steel plate 4; in addition, when the expansion joint 10 changes horizontally, the base... 2 and base 21 are pushed inward or pulled outward respectively. At this time, the two sets of horizontal plates 92 move relative to each other, and the connecting spring 94 and the protective sleeve 95 deform and expand. During the movement of the horizontal plate 92, the slider 921 drives one end of the movable plate 9 on both sides to move, and the other end rotates axially along the side wall of base 2 and base 21. This satisfies the requirement of stable connection when the deformation joint 10 changes horizontally, and also ensures auxiliary support for the bending part of the waterproof strip 3, preventing the waterproof strip 3 from being damaged by gravity.
