Description

Technical Field

[0001] This utility model relates to the field of hydraulic structures technology, specifically a settlement joint structure for hydraulic structures. Background Technology

[0002] Settlement joints are vertical joints designed to prevent damage to hydraulic structures caused by uneven settlement of the foundation. Due to foundation problems, buildings may experience uneven settlement in certain areas, leading to cracks in the building walls. Therefore, settlement joint structures are needed to divide the building into multiple blocks to prevent settlement and cracking.

[0003] A Chinese patent with authorization announcement number CN 221627304 U discloses a settlement joint structure for hydraulic structures. This utility model includes two walls with a settlement joint between them. An insulation board is installed on the inner side of the settlement joint, and waterproof strips are installed on both the front and rear sides of the insulation board. A limit plate is installed on the outer side of the waterproof strips. An installation unit is installed on the front side of the wall, including an installation frame fixedly connected to the outer wall of the settlement joint. A rectangular groove is provided on the front side of the installation frame, and a moving rod is installed on the inner side of the rectangular groove. One end of the moving rod passes through the outer side of the installation frame and is fixedly connected to a clamping plate. This utility model, by incorporating an installation frame, rectangular groove, push plate, moving rod, clamping plate, spring, airbag, connecting pipe, and discharge pipe, facilitates easy installation by allowing workers to quickly reinforce the waterproof strips with the clamping plate by discharging gas from the airbag, thus increasing the waterproofness of the settlement joint. The operation is simple.

[0004] In existing settlement joint structures, the waterproof strip is stretched during settlement, and the connection is prone to breakage over time, resulting in reduced waterproofing and poor waterproofing performance. Therefore, a new settlement joint structure for hydraulic structures is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a settlement joint structure for hydraulic structures.

[0006] The technical solution adopted by this utility model to solve its technical problem is a settlement joint structure for hydraulic structures, including an inner wall, on which two outer walls are installed, with a settlement joint between the two outer walls. An aluminum alloy base is installed on the outer wall, and sealant is applied between the aluminum alloy base and the outer wall. Multiple sets of expansion bolts are fixedly installed on the aluminum alloy base and the outer wall. Multiple sets of slide rails are provided on the aluminum alloy base, and sliders are assembled inside the slide rails. A waterproof strip is installed on the slider. The waterproof strip is made of aluminum alloy, and a sealing gasket made of polytetrafluoroethylene is fixedly attached to the bottom side of the waterproof strip. A connecting piece is fixedly installed on the bottom side of the aluminum alloy base. The connecting piece has an arc-shaped structure, and a fixing seat is installed on the bottom side of the connecting piece. The fixed base is equipped with multiple sets of nuts, and the waterproof strip has threaded holes. Fastening bolts are installed on the waterproof strip and nuts. When settlement occurs, the settlement joint between the two outer walls will increase, thus causing the two outer walls to move the two aluminum alloy bases. The two aluminum alloy bases will move in opposite directions when pulled, and the two aluminum alloy bases will stretch and deform the two connecting pieces. The fixed base will not move, and the waterproof strip on it will not move under the fixation of the fixed base. However, the two aluminum alloy bases move in opposite directions relative to the waterproof strip, that is, the two rows of slide rails slide in opposite directions relative to the slider. In other words, when the two aluminum alloy bases are pulled, the waterproof strip slides on them and will not be pulled by them. Therefore, the waterproof strip will not break, and water leakage will not occur, which helps to improve the waterproofness of the device.

[0007] Preferably, a waterproof film with an arc-shaped structure is fixedly installed on the inner wall of the settlement joint. A fire-resistant strip with an arc-shaped structure is also fixedly installed on the inner wall of the settlement joint, consisting of a steel plate support and rock wool filler. The rock wool filler is filled within the steel plate support. An insulation board, made of polystyrene foam, is also fixedly installed on the inner wall of the settlement joint. By installing the waterproof film on the inner wall of the settlement joint, a second waterproofing treatment is achieved. The fire-resistant strip, consisting of a steel plate support and rock wool filler, reinforces the settlement joint and provides fire resistance. Finally, the insulation board is installed on the inner wall of the settlement joint, thus filling the joint. This structure provides multiple layers of protection for the interior of the settlement joint, including waterproofing, fireproofing, and reinforcement, which helps improve the protective performance of the device.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes the principle that when settlement occurs, the settlement joint between the two outer walls widens, causing the two outer walls to move the two aluminum alloy bases. The two aluminum alloy bases are pulled and move in opposite directions, causing the two connecting pieces to be deformed. The fixing base does not move, and the waterproof strip on it does not move under the fixation of the fixing base. However, the two aluminum alloy bases move in opposite directions relative to the waterproof strip, that is, the two rows of slide rails slide in opposite directions relative to the slider. In other words, when the two aluminum alloy bases are pulled, the waterproof strip slides on them and is not pulled by them. Therefore, the waterproof strip will not break, and water leakage will not occur, which helps to improve the waterproofness of the device.

[0010] 2. This utility model achieves secondary waterproofing of the settlement joint by installing a waterproof film on the inner wall of the settlement joint. A fire-resistant strip, consisting of a steel plate support and rock wool filler, is installed on the inner wall of the settlement joint. The steel plate support reinforces the settlement joint and provides fire resistance. Finally, an insulation board is installed on the inner wall of the settlement joint to fill it. This structure provides multiple protections for the interior of the settlement joint, including waterproofing, fireproofing, and reinforcement, which helps to improve the protective performance of the device.

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-5 As shown, a settlement joint structure for hydraulic structures includes an inner wall 1, two outer walls 2 mounted on the inner wall 1, with a settlement joint 17 between the two outer walls 2, an aluminum alloy base 3 mounted on the outer wall 2, sealant 4 applied between the aluminum alloy base 3 and the outer wall 2, multiple sets of expansion bolts 5 fixedly mounted on the aluminum alloy base 3 and the outer wall 2, multiple sets of slide rails 6 provided on the aluminum alloy base 3, sliders 7 assembled inside the slide rails 6, and a waterproof strip 8 mounted on the slider 7. The waterproof strip 8 is made of aluminum alloy, and a sealant is fixedly adhered to the bottom side of the waterproof strip 8. Gasket 9, made of polytetrafluoroethylene, is fixedly mounted on the bottom side of aluminum alloy base 3 with connecting piece 10, which has an arc-shaped structure. A fixing seat 11 is mounted on the bottom side of connecting piece 10, and multiple sets of nuts 12 are installed on the fixing seat 11. Threaded holes are opened on the waterproof strip 8, and fastening bolts 13 are installed on the waterproof strip 8 and nuts 12. During operation, in the existing settlement joint structure, when connecting settlement joint 17, the waterproof strip 8 is stretched during settlement, and the connection is prone to breakage over time, reducing the waterproofing effect. The low pressure resulted in poor waterproofing of the device. To address this, two aluminum alloy bases 3 were fixed to two outer wall panels 2 using sealant 4, and then reinforced with expansion screws 5, thus achieving a fixed connection between the two aluminum alloy bases 3 and the two outer wall panels 2. The two aluminum alloy bases 3 were fixedly connected to the fixing seat 11 via two connecting pieces 10, forming a single integrated structure. Then, the slider 7 on the bottom side of the waterproof strip 8 was slid into the slide rail 6 of the aluminum alloy base 3, connecting the waterproof strip 8 to the two aluminum alloy bases 3. A sealing gasket 9 was attached to the bottom side of the waterproof strip 8. The sealing gasket 9 is made of polytetrafluoroethylene (PTFE), which has high chemical corrosion resistance and extremely low coefficient of friction. The PTFE sealing gasket 9 has excellent sliding performance, is wear-resistant, and high-temperature resistant. Therefore, the sealing gasket 9 on the waterproof strip 8 can slide on the aluminum alloy base 3. Then, three sets of fastening bolts 13 are screwed into the waterproof strip 8 and the nut 12, which realizes the fixed connection between the waterproof strip 8 and the fixing seat 11, and realizes the pressing of the waterproof strip 8, so that the sealing gasket 9 fits tightly with the aluminum alloy base 3, thus achieving waterproofing.

[0020] When settlement occurs, the two outer walls 2 are connected by a settlement joint structure, thus preventing cracking of the outer walls 2. However, the settlement joint 17 between the two outer walls 2 will increase, causing the two outer walls 2 to move the two aluminum alloy bases 3. The two aluminum alloy bases 3 will be pulled and move in opposite directions, which will deform the two connecting pieces 10. The fixing seat 11 will not move, and the waterproof strip 8 on it will not move under the fixation of the fixing seat 11. However, the two aluminum alloy bases 3 move in opposite directions relative to the waterproof strip 8, that is, the two rows of slide rails 6 slide in opposite directions relative to the slider 7. That is, when the two aluminum alloy bases 3 are pulled, the waterproof strip 8 slides on them and will not be pulled by them. Therefore, the waterproof strip 8 will not break, and there will be no water leakage, which helps to improve the waterproofness of the device.

[0021] Please see Figure 1 As shown, a waterproof sheet 14 is fixedly installed on the inner wall of the settlement joint 17. The waterproof sheet 14 has an arc-shaped structure. A fire-resistant strip 15 is fixedly installed on the inner wall of the settlement joint 17. The fire-resistant strip 15 has an arc-shaped structure and is composed of a steel plate support and rock wool filler. The rock wool filler is filled in the steel plate support. An insulation board 16, which is a polystyrene foam board, is fixedly installed on the inner wall of the settlement joint 17. During operation, the existing settlement joint structure makes it difficult to protect the settlement joint 17 during the connection process, resulting in... The original structure had poor protection. By installing a waterproof film 14 on the inner wall of the settlement joint 17, a second waterproofing treatment was achieved for the settlement joint 17. A fire-resistant strip 15 was installed on the inner wall of the settlement joint 17. The fire-resistant strip 15 consisted of a steel plate support and rock wool filler. The steel plate support reinforced the settlement joint 17 and also provided fire resistance. Finally, an insulation board 16 was installed on the inner wall of the settlement joint 17 to fill the settlement joint 17. This structure can provide multiple protections for the interior of the settlement joint 17, including waterproofing, fireproofing, and reinforcement, which helps to improve the protection of the device.

[0022] Working principle: In the existing settlement joint structure, during the connection of settlement joint 17, the waterproof strip 8 is stretched when settlement occurs, and the connection is prone to breakage after a long time, reducing the waterproof effect and resulting in poor waterproof performance of the device. By fixing the two aluminum alloy bases 3 to the two outer walls 2 with sealant 4, and then reinforcing them with expansion screws 5, the two aluminum alloy bases 3 and the two outer walls 2 are fixedly connected. The two aluminum alloy bases 3 are fixedly connected to the fixing seat 11 by two connecting pieces 10, forming an integral structure. Then, the slider 7 on the bottom side of the waterproof strip 8 is slid into the slide rail 6 of the aluminum alloy base 3, realizing the connection between the waterproof strip 8 and the two aluminum alloy bases 3. Next, a sealing gasket 9 is attached to the bottom side of the waterproof strip 8. The sealing gasket 9 is made of polytetrafluoroethylene (PTFE), which has high chemical corrosion resistance and an extremely low coefficient of friction. The PTFE sealing gasket 9 also exhibits excellent sliding performance, is wear-resistant, and high-temperature resistant. Therefore, the sealing gasket 9 on the waterproof strip 8 can slide on the aluminum alloy base 3. Then, three sets of fastening bolts 13 are screwed into the waterproof strip 8 and nuts 12, achieving a fixed connection between the waterproof strip 8 and the fixing seat 11. This presses down on the waterproof strip 8, ensuring a tight fit between the sealing gasket 9 and the aluminum alloy base 3, thus achieving waterproofing. When settlement occurs, the two outer wall sections 2 are connected by a settlement joint structure, thus preventing the outer wall 2 from opening. Cracks will appear, but the settlement joint 17 between the two outer wall panels 2 will increase. Therefore, the two outer wall panels 2 will move the two aluminum alloy bases 3. The two aluminum alloy bases 3 will be pulled and move in opposite directions. The two aluminum alloy bases 3 will pull and deform the two connecting pieces 10. The fixing seat 11 will not move. At the same time, the waterproof strip 8 on it will not move under the fixation of the fixing seat 11. However, the two aluminum alloy bases 3 move in opposite directions relative to the waterproof strip 8. That is, the two rows of slide rails 6 slide in opposite directions relative to the slider 7. That is, when the two aluminum alloy bases 3 are pulled, the waterproof strip 8 slides on them and will not be pulled. Therefore, the waterproof strip 8 will not break, and water leakage will not occur. This is beneficial to improving the waterproofness of the device. The existing settlement joint structure makes it difficult to protect the settlement joint 17 during the connection process, resulting in poor protection of the device. By installing a waterproof film 14 on the inner wall of the settlement joint 17, a second waterproof treatment is achieved. A fire-resistant strip 15 is installed on the inner wall of the settlement joint 17. The fire-resistant strip 15 is composed of a steel plate support and rock wool filler. The steel plate support reinforces the settlement joint 17 and can also provide fire resistance. Finally, an insulation board 16 is installed on the inner wall of the settlement joint 17 to fill the settlement joint 17. This structure can provide multiple protections for the interior of the settlement joint 17, including waterproofing, fireproofing, and reinforcement, which helps to improve the protection of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
