Description

Technical Field

[0001] This utility model relates to the field of basement construction technology, specifically to a seepage-proof structure for basement expansion joints. Background Technology

[0002] Basements differ from above-ground buildings in that they bear greater pressure, especially large-span, continuous basements. During construction, the deformation of the foundation must be taken into account, and expansion joints are one of the effective methods to solve this problem. Expansion joints refer to expansion joints, settlement joints, etc., that exist in underground engineering. These joints are weak points in waterproofing.

[0003] The patent application "CN218813908U" discloses a waterproof structure for basement expansion joints. It includes a basement floor with a pre-existing expansion joint. Supporting devices are fixedly installed on the inner walls of both sides of the expansion joint. Rubber airbags are positioned between the supporting devices and are fixedly connected to them. The side walls of the rubber airbags abut against the inner walls of the expansion joint. One end of each rubber airbag is fixedly connected to an inflation tube communicating with its inner cavity. A one-way valve is fixedly installed at the end of the inflation tube outside the rubber airbag. This patented technology allows the inflated rubber airbag to contact the side walls of the expansion joint, and the compression of the gas ensures a tight seal between the airbag and the joint side walls, minimizing the problem of existing waterproof structures failing to achieve a tight seal.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] For example, the function of expansion joints is to provide pre-set gaps for building structures to crack due to stress caused by factors such as temperature changes, humidity changes, and load effects. The spacing of these gaps will change accordingly based on the above changes. This means that when the gaps become larger, the rubber airbags cannot fit against the sidewalls of the gaps in time, and waterproofing cannot be guaranteed. When the gaps become smaller, the rubber airbags will be compressed and are prone to rupture due to excessive pressure, affecting normal use. Utility Model Content

[0006] The purpose of this utility model is to provide a seepage-proof structure for basement expansion joints to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waterproof structure for basement expansion joints includes a wall, an expansion joint is provided in the middle of the wall, and an air bladder is provided on the inner wall of the expansion joint. A groove is provided on the upper surface of the wall, and an adjustment mechanism is provided on the inner wall of the groove corresponding to the air bladder.

[0009] The adjustment mechanism includes an adjustment cylinder, the outer wall of which is fixedly connected to the inner wall of the groove. A sealing disc is slidably connected to the inner wall of the adjustment cylinder, and a limit block is symmetrically fixedly connected to the outer wall of the sealing disc. Limit grooves are formed at equal intervals on the inner wall of the adjustment cylinder corresponding to the sealing disc. A spring is fixedly connected to the side wall of the limit block away from the middle of the adjustment cylinder, and the other end of the spring is fixedly connected to the inner wall of the limit groove.

[0010] Preferably, the outer wall of the limiting block slides in contact with the inner wall of the limiting groove, an air inlet pipe is fixedly connected to the middle outer wall of the adjusting cylinder, a first cover plate is threadedly connected to the surface of the wall, and a second cover plate is threadedly connected to the surface of the wall. The top of the first cover plate and the second cover plate are provided with through slots corresponding to the air inlet pipes, and a shielding plate is fixedly installed on the top of the first cover plate and the second cover plate corresponding to the through slots.

[0011] Preferably, the outer wall of the air intake pipe is threaded with a sealing cap, and the air intake pipe is connected to the inner wall of the regulating cylinder.

[0012] Preferably, a delivery pipe is fixedly connected to the outer wall of the middle part of the regulating cylinder, and the other end of the delivery pipe passes through the inside of the wall and is fixedly connected to the outer wall of the airbag.

[0013] Preferably, the inner wall of the expansion joint is provided with a water-permeable hole, and the inner wall of the water-permeable hole is connected to the inner wall of the groove.

[0014] Preferably, a partition plate is fixedly connected to the inner wall of the groove, and a drain pipe is fixedly connected to the inside of the wall, with one end of the drain pipe communicating with the inner wall of the groove.

[0015] Preferably, a slider is fixedly connected to the side wall of the second cover plate facing the first cover plate, and a telescopic groove is provided on the side wall of the first cover plate facing the second cover plate, wherein the outer wall of the slider slides in contact with the inner wall of the telescopic groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When using this structure, after the airbag is inflated and fits against the inner wall of the expansion joint, the air pressure synchronously pushes the two sealing discs, causing them to move away from each other to store air. When the gap widens, the spring rebounds, bringing the two sealing discs closer together and pushing the air into the airbag in time. When the gap narrows, the air pressure in the regulating cylinder increases, causing the two sealing discs to move away from each other again, achieving a buffering effect. This prevents excessive pressure from causing rupture and ensures timely contact with the side wall of the gap, thus guaranteeing the waterproof effect of this structure.

[0018] 2. When this structure is in use, the water that remains on the surface of the airbag can be discharged in time through the combination of water-permeable holes and drainage pipes, which prevents rainwater from remaining on the surface of the airbag for a long time and causing corrosion. At the same time, the air intake pipe is protected by the combination of through grooves and shielding plates, which prevents it from being exposed to the outside and damaged, thus ensuring the service life of this structure.

[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. Example 1:

[0025] Please see Figure 1-4 This utility model provides a seepage-proof structure for basement expansion joints, including a wall 1, an expansion joint in the middle of the wall 1, an airbag 2 on the inner wall of the expansion joint, a groove 3 on the upper surface of the wall 1, and an adjustment mechanism 4 on the inner wall of the groove 3 corresponding to the airbag 2. A slider 12 is fixedly connected to the side wall of the second cover plate 6 facing the first cover plate 5, and an expansion groove 13 is opened on the side wall of the first cover plate 5 facing the second cover plate 6. The outer wall of the slider 12 slides in contact with the inner wall of the expansion groove 13.

[0026] Furthermore, the adjustment mechanism 4 includes an adjustment cylinder 401, and the outer wall of the adjustment cylinder 401 is fixedly connected to the inner wall of the groove 3. The surface of the wall 1 is threadedly connected to a first cover plate 5, and the surface of the wall 1 is threadedly connected to a second cover plate 6. The top of the first cover plate 5 and the second cover plate 6 are respectively provided with a through groove 7 through the air inlet pipe 406. The top of the first cover plate 5 and the second cover plate 6 are respectively fixedly installed with a shielding plate 8 corresponding to the through groove 7. The outer wall of the air inlet pipe 406 is threadedly connected to a sealing cover 408.

[0027] In this embodiment, firstly, an air inlet pipe 406 is fixedly connected to the outer wall of the middle part of the regulating cylinder 401, and the air inlet pipe 406 is connected to the inner wall of the regulating cylinder 401. Furthermore, an air valve is installed inside the air inlet pipe 406. Thus, when this structure is used, gas can be delivered to the regulating cylinder 401 through the air inlet pipe 406. Next, a delivery pipe 407 is fixedly connected to the outer wall of the middle part of the regulating cylinder 401, and the other end of the delivery pipe 407 passes through the inside of the wall 1 and is fixedly connected to the outer wall of the airbag 2. This allows the gas inside the regulating cylinder 401 to enter the inner wall of the airbag 2 through the delivery pipe 407, causing the airbag 2 to expand within the expansion joint.

[0028] Then, during the expansion process, a sealing disc 402 is slidably connected to the inner wall of the adjusting cylinder 401, and a limiting block 404 is symmetrically fixed to the outer wall of the sealing disc 402. A limiting groove 403 is opened at equal distances on the inner wall of the adjusting cylinder 401 corresponding to the sealing disc 402. At the same time, a spring 405 is fixedly connected to the side wall of the limiting block 404 away from the middle of the adjusting cylinder 401, and the other end of the spring 405 is fixedly connected to the inner wall of the limiting groove 403. The outer wall of the limiting block 404 slides in contact with the inner wall of the limiting groove 403. Thus, before the airbag 2 expands, the two sealing discs 402 approach the middle position of the adjusting cylinder 401 under the push of the spring 405.

[0029] When the airbag 2 begins to inflate until it fits against the inner wall of the expansion joint, gas continues to be supplied, causing the outer surface of the airbag 2 to press against the inner wall of the expansion joint. During this process, the internal air pressure of the regulating cylinder 401 gradually increases, thereby pushing the two sealing discs 402, causing the two sealing discs 402 to move away from each other by a certain distance and compressing the spring 405. At this point, the inflation process is complete.

[0030] When the gap widens, the spring 405 rebounds, bringing the two sealing discs 402 closer together. This allows the stored gas to be promptly pushed into the airbag 2 for replenishment, preventing the outer surface of the airbag 2 from separating from the inner wall of the expansion joint and causing water leakage. When the gap narrows, the wall 1 compresses the airbag 2, causing some of the gas inside the airbag 2 to return to the regulating cylinder 401 through the delivery pipe 407. This increases the air pressure inside the regulating cylinder 401, further distancing the two sealing discs 402 from each other, storing more gas, and achieving a buffering effect. This prevents rupture due to excessive pressure and ensures timely contact with the side wall of the expansion joint. Simultaneously, the through groove 7 and the shielding plate 8 protect the air inlet pipe 406 from external damage, ensuring the service life of the structure. Example 2:

[0031] Based on the above embodiments, the inner wall of the expansion joint is provided with a water-permeable hole 9, and the inner wall of the water-permeable hole 9 is connected to the inner wall of the groove 3. The inner wall of the groove 3 is fixedly connected with a partition plate 10, and the interior of the wall 1 is fixedly connected with a drain pipe 11, one end of the drain pipe 11 is connected to the inner wall of the groove 3.

[0032] In this embodiment, when the structure is used, a water-permeable hole 9 is provided through the inner wall of the expansion joint, and the inner wall of the water-permeable hole 9 is connected to the inner wall of the groove 3. This allows rainwater and other water that is trapped on the outer surface of the airbag 2 to flow through the water-permeable hole 9 to the inner wall of the groove 3. A partition plate 10 is fixedly connected to the inner wall of the groove 3, and a drain pipe 11 is fixedly connected to the inside of the wall 1. One end of the drain pipe 11 is connected to the inner wall of the groove 3. The partition plate 10 reduces the space inside the groove 3, and the rainwater is collected at the inlet of the drain pipe 11. This makes it easier to drain the water trapped on the surface of the airbag 2 in a timely manner, and prevents the airbag 2 from being corroded due to prolonged retention of rainwater on the surface of the airbag 2.

[0033] Working principle: First, remove the shielding plate 8, then unscrew the sealing cap 408 at the end of the air inlet pipe 406. Use the air inlet pipe 406 to deliver gas into the regulating cylinder 401, and then through the delivery pipe 407 into the inner wall of the airbag 2, causing the airbag 2 to expand within the deformation joint. When the airbag 2 begins to expand until it fits against the inner wall of the deformation joint, continue to deliver gas, causing the outer surface of the airbag 2 to begin to press against the inner wall of the deformation joint. During this process, the internal air pressure of the regulating cylinder 401 gradually increases, thereby pushing the two sealing discs 402, causing the two sealing discs 402 to move away from each other by a certain distance and compressing the spring 405. At this point, the inflation process is complete.

[0034] When the gap widens, the spring 405 rebounds, causing the two sealing discs 402 to approach each other, thus allowing the stored gas to be pushed into the airbag 2 for replenishment. When the gap narrows, the wall 1 will compress the airbag 2, causing some of the gas inside the airbag 2 to return to the regulating cylinder 401 through the delivery pipe 407, increasing the air pressure in the regulating cylinder 401. This further causes the two sealing discs 402 to move away from each other, storing more gas and achieving a buffering effect.

[0035] Then, rainwater and other water trapped on the outer surface of the airbag 2 can flow through the water-permeable holes 9 to the inner wall of the groove 3. The partition plate 10 reduces the space inside the groove 3, and the rainwater is collected at the inlet of the drain pipe 11. This makes it easier to drain the water trapped on the surface of the airbag 2 in a timely manner, and prevents the airbag 2 from being corroded by rainwater trapped on the surface of the airbag 2 for a long time.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
