Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a sealing device for joints of prefabricated concrete composite slabs. Background Technology

[0002] The prefabricated concrete composite slab joint sealing device is a specialized component designed to address grout leakage issues during cast-in-place construction of composite slab joints. Its core function is to seal horizontal or vertical joints formed after the splicing of prefabricated composite slabs, ensuring the quality of cast-in-place concrete. It is widely applicable to prefabricated projects such as residential and public buildings. During operation, a rigid main component adheres to the bottom of the joint to form the first sealing barrier. Elastic seals on both sides are pushed tightly against the composite slab by adjusting components, blocking the grout leakage path. Drainage holes can divert a small amount of overflowing grout, preventing contamination and accumulation at the bottom of the slab. During pouring, the device firmly fixes the formwork, preventing displacement due to concrete lateral pressure and ensuring precise control of the joint width. Its core function is to solve the pain point of frequent grout leakage in traditional single-seal methods, ensuring the density of concrete at the joint, reducing later repair costs, and improving the joint's load-bearing capacity and waterproofing performance. Since the connection between the sealing plates directly affects the subsequent concrete pouring effect, a sealing connection operation is necessary.

[0003] In related technologies, during the use of sealing devices, the sealing plates are generally aligned and fitted together to prepare for subsequent concrete pouring before use.

[0004] However, in the current use of sealing devices, the alignment and bonding method can only achieve a simple connection between two sealing plates. Concrete has a certain weight, and it is very easy for the bonding force between the sealing plates to be insufficient and shift, resulting in leakage at the joint of the composite plate. This affects the sealing connection and sealing effect of the sealing plate device. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4 This utility model provides a technical solution: a prefabricated concrete composite slab joint sealing device, including a support column 1 and a sealing and docking mechanism. A lifting column 2 is installed inside the support column 1, and a sealing plate 3 is movably connected to the top of the lifting column 2. This allows for the construction docking and fitting of the sealing plates 3, enabling users to perform construction docking operations between the sealing plates 3. This avoids the situation where the sealing plates 3 shift due to insufficient docking force, leading to leakage when pouring concrete at the joint of the composite slab. Therefore, it improves the sealing and docking effect and sealing effect of the sealing plates 3.

[0021] Reference Figures 1-4 In a preferred embodiment, the sealing and docking mechanism includes a docking seat 4, which is movably connected to the right side of the bottom of the sealing plate 3. Both sides of the docking seat 4 are fixedly connected to docking plates 5. A docking groove 6 is formed on the left side of the bottom of the sealing plate 3. A docking strip 7 is fixedly connected to the top of the docking seat 4. A lifting and positioning mechanism is movably connected to the top of the outside of the support column 1. After one sealing plate 3 is supported and sealed by the support column 1 and the lifting column 2, the other sealing plate 3 is moved, and the docking seat 4 drives the docking strip 7 to align with the docking groove 6, allowing the docking strip 7 to enter the docking groove 6. At this time, the docking plate 5 is fitted onto the outside of the docking point of the two sealing plates 3, allowing the docking seat 4 to cooperate with the docking plate 5 to pass through. The two sealing plates 3 are connected and reinforced by the docking strip 7 and the docking groove 6. The lifting and positioning mechanism includes a positioning cylinder 8, a positioning column 9 and a positioning hole 10. The positioning cylinder 8 is movably connected to the top of the outside of the support column 1, and the positioning column 9 is movably connected to the top of the front side of the positioning cylinder 8. The positioning hole 10 is opened on the front side of the lifting column 2, and the rear side of the positioning column 9 is located inside the positioning hole 10. It can perform positioning work between the support column 1 and the lifting column 2 after the lifting operation, so that the user can perform the insertion and positioning operation between the lifting column 2 and the support column 1. This avoids the situation where the lifting column 2 is difficult to adjust and position during use, thus improving the positioning effect between the lifting column 2 and the support column 1.

[0022] Reference Figures 2-3 In a preferred embodiment, a threaded groove 11 is provided at the bottom of the inner wall of the positioning cylinder 8. A threaded ring 12 is threadedly connected to the inside of the threaded groove 11. The inner side of the threaded ring 12 is fixedly connected to the outer side of the support column 1. The positioning cylinder 8 can be used to make fine adjustments between the lifting column 2 and the support column 1, so that the user can make fine adjustments between the support column 1 and the lifting column 2. This improves the flexibility of the positioning cylinder 8. A threaded cylinder 13 connected to the positioning hole 10 is fixedly connected to the top of the front side of the positioning cylinder 8. A threaded stud 14 fixedly connected to the positioning column 9 is threadedly connected to the inside of the threaded cylinder 13. This can make the threaded connection between the positioning column 9 and the positioning cylinder 8 secure, preventing the positioning column 9 from coming out of the positioning hole 10 during use. This improves the working stability of the positioning column 9.

[0023] Reference Figures 2-4 In a preferred embodiment, a force-applying handle 15 is movably connected to the top of the left side of the support column 1. The right side of the force-applying handle 15 is fixedly connected to the left side of the positioning cylinder 8, which provides a medium for the user to rotate the positioning cylinder 8 to work with the screw ring 12. This improves the ease of force application operation of the positioning cylinder 8. A force-applying plate 16 that contacts the sealing plate 3 is movably connected to the top of the lifting column 2. An installation bolt 17 that is threadedly connected to the lifting column 2 is movably connected inside the force-applying plate 16. This increases the support area between the lifting column 2 and the sealing plate 3, thus improving the support effect of the lifting column 2 on the sealing plate 3.

[0024] Reference Figure 2 In a preferred embodiment, screw holes 18 are provided on both sides of the bottom of the docking seat 4. Bolts 19 that are threaded to the sealing plate 3 are connected to the screw holes 18. This allows for the installation and fixing of the sealing plate 3 and the docking seat 4 to prevent displacement and separation, thus improving the connection effect between the docking seat 4 and the sealing plate 3. A support plate 20 is fixedly connected to the bottom of the support column 1, and a reinforcing plate 21 is fixedly connected to the top of the support plate 20. The inner side of the reinforcing plate 21 is fixedly connected to the outer side of the support column 1, which increases the support area of ​​the support column 1 during operation, thus improving the support effect of the support column 1.

[0025] Specifically, the working process or working principle of this prefabricated concrete composite slab joint sealing device is as follows: In use, the sealing plate 3 is first tilted, and the lifting column 2 moves the force-applying plate 16 to the bottom of the sealing plate 3, supporting the sealing plate 3 at the bottom of the external composite slab joint. Since the top of the force-applying plate 16 and the bottom of the sealing plate 3 are connected via slots, the connection between the force-applying plate 16 and the lifting column 2 during the operation of supporting the sealing plate 3 is maintained. At this time, the mounting bolt 17 performs installation connection and stability work between the force-applying plate 16 and the lifting column 2 to prevent separation. During this process, the support column 1 and the lifting column 2 should be perpendicular to the bottom of the force-applying plate 16 and the sealing plate 3. At this time, the support column 1, through the reinforcing plate 21, drives the support plate 20 downwards to contact the ground, forming a support base. The hand-held stud 14 drives the positioning column 9 to move backwards and insert it into the positioning hole 10, thus positioning the support cylinder and the lifting column 2. The process begins with the hand-held stud 14 being rotated into the screw cylinder 13 to tighten the threads between the positioning pin 9 and the positioning cylinder 8, preventing separation. Subsequently, the positioning cylinder 8 is rotated using the force-applying handle 15, causing it to rotate the screw groove 11 to engage with the screw ring 12. Through the positioning pin 9 and the positioning hole 10, the lifting pin 2, in conjunction with the force-applying plate 16, further applies upward support to the sealing plate 3, ensuring a tight fit between the top of the sealing plate 3 and the bottom of the joint of the external composite plate. Then, another sealing plate 3 is moved, and the docking seat 4 drives the docking strip 7 into the docking groove 6 of the previously supported sealing plate 3. At this point, the docking plate 5 moves to the outside of the docking point of the two sealing plates 3, engaging with the docking seat 4 to reinforce the connection between the sealing plates 3. Finally, the support pin 1, through the lifting seat and the force-applying plate 16, provides stable support between the two connected sealing plates 3, ensuring the effective connection between them.

[0026] It should be noted that the support column 1, the lifting column 2 and the sealing plate 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
