[0001] This utility model belongs to the field of grouting auxiliary technology, specifically relating to a grouting repair structure for waterproof expansion joint sealing plates. Background Technology

[0002] In building construction, waterproof expansion joints are designed to address structural deformation caused by factors such as temperature changes and foundation settlement, thereby preventing structural damage and leakage. However, over time and due to external environmental factors, the sealing plates of waterproof expansion joints may age, crack, or become inadequately sealed, leading to leakage and affecting the normal use and safety of the building.

[0003] Traditional methods for repairing waterproof expansion joint sealing plates are often cumbersome and the repair effect is difficult to guarantee. For example, some repair methods involve grouting the sealing plate of the waterproof expansion joint. However, traditional repair methods often make it difficult to accurately control the position and stability of the grouting head during the grouting process, resulting in unsatisfactory grouting effect and difficulty in achieving the expected waterproof and sealing effect. Therefore, this utility model provides a grouting repair structure for waterproof expansion joint sealing plates. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a waterproof expansion joint sealing grouting repair structure, including a main body 1. Two movable frames 2 are slidably connected inside the main body 1. Each movable frame 2 has movable abutment 4 at both ends of its bottom. Guide protrusions 103 are provided on both sides of the inner cavity of the main body 1. The movable abutment 4 at both ends of each movable frame 2 is slidably connected to the outside of the guide protrusions 103. A fixed frame 102 is fixedly connected to the center of the top of the main body 1 above a central frame 3. A double-threaded screw 6 is rotatably connected to the bottom of the fixed frame 102. Both ends of the 6 are provided with rotating disks 601. The double-threaded screw 6 has two sliding blocks 7 connected to its external symmetrical threads. Both ends of the top of the inner cavity of each movable frame 2 are rotatably connected with connecting plates 5, and the other end of each connecting plate 5 is rotatably connected to one side of the sliding block 7 in the corresponding direction. The bottom of the movable contact part 4 is provided with a vertical contact part 402. The outer surface of the movable contact part 4 is provided with a fitting part 401. The bottom of both ends of the main body 1 is provided with support pads 101. The height of the support pads 101 is the same as the distance between the top of the contact part 402 and the main body 1.

[0022] The waterproof expansion joint sealing grouting repair structure is erected above the expansion joint by the main structure 1. The support pad 101 contacts the building surfaces on both sides of the expansion joint to provide initial support. The contact part 402 of the movable contact part 4 is at the same horizontal height as the support pad 101, and the fitting part 401 faces both sides of the expansion joint, waiting for adjustment. By rotating the rotating disks 601 at both ends of the double-threaded screw 6, the double-threaded screw 6 is driven to rotate. Since there are two sliding blocks 7 connected to the external symmetrical threads of the double-threaded screw 6, when rotating, the two sliding blocks 7 move towards or away from each other along the axial direction of the double-threaded screw 6. The movement of the sliding blocks 7 is transmitted to the movable frame 2 through the connecting plate 5. The connecting plate 5 acts as a transmission component, converting the linear movement of the sliding blocks 7 into the sliding movement of the movable frame 2. The movable frame 2 slides along the guide protrusion 103 within the main body 1 to ensure a stable movement trajectory. As the movable frame 2 slides, the movable contact part 4 gradually approaches both sides of the expansion joint. The contact part 402 first contacts the surfaces on both sides of the expansion joint to provide vertical support force and ensure structural stability. The fitting part 401 then fits tightly against both sides of the expansion joint to provide horizontal support force. After the movable contact part 4 completes its support, waterproof grout is injected into the expansion joint through the grouting head at the center of the main body 1.

[0023] The threaded connection between the double-threaded screw 6 and the sliding block 7 enables precise position adjustment of the movable frame 2, adapting to the repair needs of expansion joints of different widths and depths. The guide protrusion 103 ensures the stability of the sliding trajectory of the movable frame 2 and improves the repair accuracy. The design of the contact part 402 and the fitting part 401 of the movable contact part 4 can effectively ensure the stability of the structure.

[0024] In this embodiment, a central frame 3 is fixedly connected to the center of the main body 1. The central frame 3 is provided with a fixing member inside. The fixing member includes three arc-shaped limiting plates 303 arranged in a ring around the axis of the central frame 3 for fixing the grouting head. A circular groove 301 is opened inside the fixing member. Two elastic plates 302 are provided on the side of each arc-shaped limiting plate 303 facing the inner wall of the circular groove 301. The other end of the elastic plate 302 is connected to the inner wall of the circular groove 301. A guide portion 304 extending outward is provided at the top of each arc-shaped limiting plate 303. Friction particles are provided on the side of the arc-shaped limiting plate 303 facing the axis of the circular groove 301. The grouting head is inserted into the circular groove 301 from the guide portion 304 at the top of the fixing member.

[0025] The outward-extending inclined surface design of the guide part 304 can guide the grouting head to quickly align with the center and avoid deviation. When the grouting head is pressed down, the three arc-shaped limiting plates 303 are squeezed and expand outward, and the elastic plate 302 (spring sheet) is compressed, generating an inward elastic restoring force. When the grouting head reaches the target position, the elastic plate 302 pushes the arc-shaped limiting plate 303 to clamp the grouting head. The friction particles increase the friction of the contact surface to prevent the grouting head from sliding or falling off. The grouting head remains stable in the fixing part. The grouting material is injected into the waterproof deformation joint through the grouting head. The fixing part is rigidly connected to the main structure 1 through the central frame 3 to avoid displacement due to grouting pressure and ensure accurate grouting path. After grouting is completed, the grouting head is lifted up, and the arc-shaped limiting plate 303 automatically resets under the action of the elastic plate 302, which is convenient for reuse.

[0026] The buffer design of the elastic plate 302 allows the fixing component to adapt to grouting heads of different diameters without frequent component replacement, reducing operational complexity. The ring-shaped arc-shaped limiting plate 303 distributes force evenly at three points, preventing excessive pressure on one side from causing deformation of the grouting head or sealing failure. The guiding function of the guide part 304 reduces manual alignment errors, making it especially suitable for repairing narrow or deep expansion joints. The anti-slip design of the friction particles ensures that there is no relative displacement between the grouting head and the fixing component during high-pressure grouting, preventing grouting path deviation or leakage.

[0027] The working principle and usage process of this utility model are as follows: First, the main structure 1 is erected above the expansion joint. The support pad 101 contacts the building surfaces on both sides of the expansion joint to provide initial support. The contact part 402 of the movable contact member 4 is at the same horizontal height as the support pad 101, and the fitting part 401 faces both sides of the expansion joint, waiting for adjustment. By rotating the rotating disks 601 at both ends of the double-threaded screw 6, the double-threaded screw 6 is driven to rotate. Since there are two sliding blocks 7 connected to the external symmetrical threads of the double-threaded screw 6, when rotating, the two sliding blocks 7 move towards or away from each other along the axial direction of the double-threaded screw 6. The movement of the sliding blocks 7 is transmitted to the movable frame 2 through the connecting plate 5. The connecting plate 5 acts as a transmission component, converting the linear movement of the sliding blocks 7 into the sliding movement of the movable frame 2. The movable frame 2 slides along the guide protrusion 103 within the main structure 1 to ensure a stable movement trajectory. As the movable frame 2 slides, the movable contact part 4 gradually approaches both sides of the expansion joint. The contact part 402 first contacts the surfaces on both sides of the expansion joint, providing vertical support to ensure structural stability. The fitting part 401 then fits tightly against both sides of the expansion joint, providing horizontal support. The grouting head is inserted into the circular groove 301 from the guide part 304 at the top of the fixing part. The outwardly extending inclined surface design of the guide part 304 guides the grouting head to quickly align with the center and avoids deviation. When the grouting head is pressed down, the three arc-shaped limiting plates 303 are squeezed. As the pressure expands outward, the elastic plate 302 (spring sheet) is compressed, generating an inward elastic restoring force. When the grouting head reaches the target position, the elastic plate 302 pushes the arc-shaped limiting plate 303 to clamp the grouting head. The friction particles increase the friction of the contact surface, preventing the grouting head from sliding or falling off. The grouting head remains stable within the fixing member. The grouting material is injected into the waterproof deformation joint through the grouting head. The fixing member is rigidly connected to the main structure 1 through the central frame 3, avoiding displacement due to grouting pressure and ensuring accurate grouting path. After grouting is completed, the grouting head is lifted, and the arc-shaped limiting plate 303 automatically resets under the action of the elastic plate 302, facilitating reuse.
