Technical Field
[0001] This utility model belongs to the technical field of expansion joint repair structure, specifically a subway building expansion joint repair structure based on FPO material. Background Technology
[0002] In subway construction projects, expansion joints are key structures for dealing with structural deformation. Their sealing and waterproofing performance is directly related to the safety and durability of the building structure. Subway structures are subjected to various factors such as subway vibration, temperature changes, foundation settlement and earthquakes for a long time. Expansion joints are prone to displacement or cracking, which can lead to waterproofing failure and poor sealing. This can seriously affect the service life and operational safety of subway buildings.
[0003] Currently, in the repair of expansion joints in subway structures, some projects have adopted FPO materials (FPO flexible polyolefin is a high-performance waterproof material) to treat the expansion joints. Among them, epoxy composite FPO sealing pipes have shown application potential in expansion joint repair due to their material properties.
[0004] However, when using epoxy composite FPO sealing pipes, multiple pipes are often required to fill the cracks in the entire building. When connecting multiple epoxy composite FPO sealing pipes, flanges or direct butt joints followed by wrapping with sealing tape are commonly used. During fixing, workers need to perform the same operation repeatedly, which is too cumbersome and impractical. Therefore, to address the above problems, a subway building expansion joint repair structure based on FPO material is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 - Figure 5This utility model provides a subway building expansion joint repair structure based on FPO material, including an FPO material sealing tube 1;The first FPO material sealing tube 1 has an end contacting the second FPO material sealing tube 2. The first FPO material sealing tube 1 has an insertion assembly at its end, including a retaining ring 3 fixedly connected to the end of the first FPO material sealing tube 1. An insertion block 31 is slidably connected to the end of the retaining ring 3. The second FPO material sealing tube 2 has an insertion groove 5 at its end, with the retaining ring 3 inserted into the middle of the end of the second FPO material sealing tube 2. The insertion block 31 is inserted into the middle of the insertion groove 5, which has a limiting groove 7 in the middle. A rectangular plate 33 is slidably connected to the middle of the insertion block 31, with one end of the rectangular plate 33 fixedly connected to the end of the retaining ring 3. A limiting groove 7 is fixed to the bottom side of the other end of the rectangular plate 33. The limiting block 34 is slidably connected to the middle of the insertion block 31 on its outer wall and inserted into the middle of the limiting groove 7. During operation, FPO material sealing tube 1 and FPO material sealing tube 2 are filled into the deformation joints of the subway building. This reduces the waterproofing, sealing, and durability issues at the deformation joints when the building structure deforms under the influence of factors such as subway vibration, temperature changes, foundation settlement, and earthquakes. To ensure the sealing of the connection, FPO material sealing tube 1 and FPO material sealing tube 2 need to be butt-fitted and fixed. During fixing, simply insert the fixing ring 3 fixed to the end of FPO material sealing tube 1 into the end of FPO material sealing tube 2. The inner wall of the insertion block 31 is inserted into the middle of the insertion groove 5. When a portion of the outer wall of the insertion block 31 is inserted into the middle of the insertion groove 5, the FPO material sealing tube 1 can be rotated. The FPO material sealing tube 1 will drive the fixing ring 3 to rotate, and the fixing ring 3 will drive the rectangular plate 33 to slide in the middle of the insertion block 31. The limiting block 34 will also retract into the middle of the insertion block 31 as the rectangular plate 33 moves. Then, continue to push the FPO material sealing tube 1 to make the insertion block 31 continue to extend into the middle of the insertion groove 5. When the fixing ring 3 is fully inserted into the middle of the FPO material sealing tube 2, the FPO material sealing tube 1 and the fixing ring 3 can be rotated in opposite directions. At this time, the rectangular plate 33 and the limiting block 34 will return to their original positions. The limiting block 34 inserts into the middle of the limiting groove 7, limiting the insertion block 31. This completes the docking installation of FPO material sealing tube 1 and FPO material sealing tube 2. For disassembly, simply rotate FPO material sealing tube 1. The subsequent movement is the same: the limiting block 34 moves into the middle of the insertion block 31 and disengages from the inner wall of the limiting groove 7, allowing either FPO material sealing tube 1 or FPO material sealing tube 2 to separate. Compared to the traditional method of repeatedly wrapping sealing tape and repeatedly rotating multiple sets of bolts for fixing, this method improves installation and disassembly efficiency, enhancing the overall project efficiency and practicality.
[0027] Furthermore, such as Figure 2 and Figure 5 As shown, the FPO material sealing tube 1 has an annular groove 8 at one end, and a sealing ring 4 is inserted into the middle of the annular groove 8. The FPO material sealing tube 2 has a sealing groove 6 at one end, and the sealing ring 4 is inserted into the middle of the sealing groove 6. The inner wall of the sealing ring 4 has a groove 43, and a limiting post 41 is elastically connected to the middle of the groove 43 by a spring 42. The outer wall of the limiting post 41 is slidably connected to the middle of the groove 43. One end of the spring 42 is fixed to the top of the limiting post 41, and the other end of the spring 42 is fixed to the middle of the groove 43. The bottom of the limiting post 41 contacts the inner wall of the groove 9. During operation, when the FPO material sealing tube 1 and the FPO material sealing tube 2 are connected, the sealing ring 4 installed in the middle of the annular groove 8 at the end of the FPO material sealing tube 1 will be inserted into the middle of the sealing groove 6, further improving the sealing performance of the connection between the FPO material sealing tube 1 and the FPO material sealing tube 2. After a period of use, the sealing ring 4 may show signs of aging. It can then be disassembled and replaced. Disassembly involves simply pulling the sealing ring 4. As the sealing ring 4 moves, the limiting post 41 moves accordingly. During this movement, the limiting post 41 is squeezed by the inner wall of the annular groove 8 and disengages from the center of the second groove 9. The limiting post 41 then moves into the center of the first groove 43, simultaneously squeezing the spring 42 until the sealing ring 4 is completely disengaged from the center of the annular groove 8, completing the disassembly. For installation, the sealing ring 4 is directly inserted into the center of the annular groove 8. During insertion, the limiting post 41 is also squeezed into the center of the first groove 43, simultaneously squeezing the spring 42. When the limiting post 41 aligns with the second groove 9, the spring 42 pushes the limiting post 41 back to its original position through its elasticity, allowing the limiting post 41 to insert into the inner wall of the second groove 9, thus limiting the sealing ring 4. This quick and convenient replacement process improves ease of use.
[0028] Furthermore, such as Figure 3 As shown, the top of the rectangular plate 33 is in contact with an elastic sheet 32, and the other end of the elastic sheet 32 is fixed to the middle of the insertion block 31. When working, the elastic sheet 32 has a certain elasticity, and through its own elasticity, it can improve the stability of the limiting block 34 inserted into the middle of the limiting groove 7.
[0029] Furthermore, such as Figure 4As shown, the fixed ring 3 has a groove 36 at its end, and the plug block 31 has a slider 35 fixedly connected to its end. The outer wall of the slider 35 is slidably connected to the middle of the groove 36. The outer wall of the slider 35 and the inner cross-section of the groove 36 are both T-shaped. During operation, the cooperation between the slider 35 and the groove 36 ensures that the fixed ring 3 and the plug block 31 can slide stably relative to each other. By setting the outer wall of the slider 35 and the inner cross-section of the groove 36 to T-shape, the fixed ring 3 and the plug block 31 can be stably connected, improving practicality.
[0030] Furthermore, such as Figure 3 As shown, the bottom side of the limiting block 34 is set as an inclined surface. During operation, the inclined surface ensures that when the plug-in block 31 is inserted into the middle of the plug-in groove 5, the inner wall of the plug-in groove 5 will be pushed along the inclined surface of the limiting block 34 to move it, without the need for the worker to manually rotate it, thus improving its practicality.
[0031] Furthermore, such as Figure 5 As shown, the bottom side of the limiting post 41 is set as an arc-shaped surface. During operation, the arc-shaped surface ensures that the limiting post 41 has a certain limiting effect on the sealing ring 4, but will not jam the sealing ring 4, thus improving the convenience of disassembling and installing the sealing ring 4.
[0032] Furthermore, such as Figure 1 - Figure 2 As shown, multiple sets of plug-in components are provided, and these multiple sets of plug-in components are located at the other end of the FPO material sealing tube 2. Multiple sets of plug-in grooves 5, sealing grooves 6, and limiting grooves 7 are provided, and these multiple sets of plug-in grooves 5, sealing grooves 6, and limiting grooves 7 are located in the middle of the other end of the FPO material sealing tube 1. During operation, the multiple sets of plug-in components and multiple sets of plug-in grooves 5, sealing grooves 6, and limiting grooves 7 ensure that each set of FPO material sealing tubes can be adapted and connected, improving the convenience of installation.
[0033] Working principle: When the FPO material sealing tube 1 and the FPO material sealing tube 2 are connected, simply insert the fixing ring 3 fixed to the end of the FPO material sealing tube 1 into the inner wall of the end of the FPO material sealing tube 2. The insertion block 31 will then be inserted into the middle of the insertion groove 5. During the insertion of the insertion block 31 into the middle of the insertion groove 5, the inner wall of the insertion groove 5 will contact the limiting block 34 and push the middle of the insertion block 31 down along its inclined surface. The limiting block 34 will drive the rectangular plate 33 to move, and the rectangular plate 33 will squeeze the elastic sheet 32. At the same time, the rectangular plate 33 will drive the fixing ring 3 and the FPO material sealing tube 1 to rotate. After the fixing ring 3 is fully inserted... Insert the FPO material sealing tube 2 into the middle. At this time, the limiting block 34 will coincide with the limiting groove 7. The elastic plate 32 will push the rectangular plate 33 to reset through its own elasticity, so that the limiting block 34 is inserted into the middle of the limiting groove 7. In this way, the FPO material sealing tube 1 and the FPO material sealing tube 2 are connected and installed. When disassembling, simply rotate the FPO material sealing tube 1. The subsequent structural movement is the same as above. Move the limiting block 34 into the middle of the insertion block 31 and separate it from the inner wall of the limiting groove 7. Then you can pull the FPO material sealing tube 1 or the FPO material sealing tube 2 to separate the FPO material sealing tube 1 and the FPO material sealing tube 2.
[0034] When FPO material sealing tube 1 and FPO material sealing tube 2 are connected, the sealing ring 4 installed in the middle of the annular groove 8 at the end of FPO material sealing tube 1 will insert into the middle of the sealing groove 6, further improving the sealing performance of the connection between FPO material sealing tube 1 and FPO material sealing tube 2. After a period of use, the sealing ring 4 may show signs of aging, at which point it can be disassembled and replaced. During disassembly, simply pull the sealing ring 4. As the sealing ring 4 moves, the limiting post 41 will move accordingly. When the limiting post 41 moves, it will be squeezed by the inner wall of the annular groove 8 and will move out of the groove 2. When the middle part of 9 is disengaged, the limiting post 41 will move into the middle of the first groove 43. At the same time, the limiting post 41 will compress the spring 42 until the sealing ring 4 is completely disengaged from the middle of the annular groove 8, thus completing the disassembly. During installation, the sealing ring 4 is directly inserted into the middle of the annular groove 8. During the insertion process, the limiting post 41 will also be compressed into the middle of the first groove 43, and at the same time, it will compress the spring 42. The limiting post 41 coincides with the second groove 9. At this time, the spring 42 will push the limiting post 41 back to its original position through its own elasticity, so that the limiting post 41 is inserted into the inner wall of the second groove 9, which limits the sealing ring 4 to a certain extent. The replacement process is quick and convenient, improving the ease of use.
