Description

Technical Field

[0001] This utility model relates to the field of construction waterproofing structure technology, and in particular to a construction joint waterproofing structure. Background Technology

[0002] Construction joints are joints formed during the concrete pouring process due to design requirements or construction needs when pouring concrete in sections. Their waterproofing treatment is crucial to the durability and waterproofing performance of building structures. Currently, construction joint waterproofing technology mainly achieves waterproofing by setting waterstops and baffles, which has achieved certain results in preventing water penetration. However, there is still room for improvement in terms of construction efficiency and ease of installation.

[0003] A search revealed Chinese patent publication number CN213268012U, which discloses a waterproof structure for construction joints. The structure includes an upper structural wall and a lower structural wall, with a construction joint between them. A grouting pipe is installed within the construction joint. Several fixing components are installed on the bottom wall of the upper structural wall. A groove is reserved between the upper and lower structural walls, and a water-swellable waterproofing strip is installed within the groove. A clamping plate is installed on the side of the water-swellable waterproofing strip away from the wall. Fasteners are installed in both the upper and lower structural walls. Waterproof layers are installed on the sides of the two clamping plates away from the wall. The water-swellable waterproofing strip absorbs water and expands, adhering to the inner wall of the groove under the constraint of the clamping plate. The tight contact fills the gaps, thus achieving a good waterproof effect. After the structural wall is poured, grout is injected into the grouting pipe. The grout seeps into the construction joint through the grouting pipe wall and fills the construction joint, thus achieving a good waterproof effect. The waterproof layer on both sides of the wall can effectively prevent water from entering the construction joint and further enhance the waterproofness of the entire structure. However, in actual use, this waterproof structure requires the installation of multiple sets of fixing components. After installation, grout needs to be injected into the construction joint. The operation process is complicated and can only waterproof. If there is a lot of water and it cannot be drained in time, rainwater will corrode the seals, resulting in a poor waterproof effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waterproof structure for construction joints, which aims to improve the problem that the existing technology is complicated to operate and cannot drain water in time when there is a large amount of water, which will cause rainwater to corrode the seals and reduce the waterproof effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof structure for construction joints, comprising a V-shaped elastic metal sheet, a rubber pad fixedly connected to the outer wall of the V-shaped elastic metal sheet, straight plates provided on both the left and right sides of the inner wall of the rubber pad, multiple rotating sleeves provided on both the front and rear sides of the inner wall of the V-shaped elastic metal sheet, threaded rods threadedly connected to the left and right sides of the inner walls of the multiple rotating sleeves, and the far ends of the multiple threaded rods fixedly connected to the V-shaped elastic metal sheet, multiple screws threadedly connected to the top left and right sides of the rubber pad, the bottom ends of the multiple screws penetrating the corresponding straight plates and the rubber pad, water-blocking strips provided on both the left and right sides of the outer wall of the rubber pad, and a filtering mechanism provided on the inner wall of the V-shaped elastic metal sheet.

[0006] The above technical solution utilizes a V-shaped elastic metal sheet as the basic frame. Its unique V-shaped design serves dual purposes: insertion into construction joints and effective drainage. This prevents rainwater accumulation from corroding the sealing components. The rubber gasket fixed to the outer wall of the V-shaped elastic metal sheet enhances the fit with the walls on both sides of the construction joint, improving sealing performance. Straight plates are located on the left and right sides inside the rubber gasket, with a 90-degree angle in the middle. When the rubber gasket is compressed, the straight plates assist in tightly adhering to the wall. Furthermore, during screw tightening, the compressive force on the straight plates further promotes a tighter fit between the bottom of the rubber gasket and the wall, achieving a dual sealing effect. Multiple rotating sleeves are arranged on the front and back sides of the inner wall of the rubber pad. These rotating sleeves work in conjunction with the threaded rods connected to the threads on the left and right sides of the inner wall. When the rotating sleeves are rotated, the threaded rods move to both sides, squeezing the left and right sides of the V-shaped elastic metal sheet, causing the rubber pad to fit tightly against the walls on both sides. This allows for flexible adjustment of the sealing force according to the actual condition of the construction joint. In addition, multiple screws are connected to the top left and right sides of the rubber pad through the threads. These screws pass through the straight plate and the rubber pad. When tightened, they squeeze the straight plate, indirectly strengthening the adhesion between the rubber pad and the wall and consolidating the sealing effect. The water-retaining strips set on the left and right sides of the outer wall of the rubber pad can further prevent water from seeping from the sides and enhance the waterproof performance.

[0007] As a further description of the above technical solution:

[0008] The filtering mechanism includes two fixed seats 1. The left sides of the two fixed seats 1 are respectively fixedly connected to the front and rear sides of the left end of the inner wall of the V-shaped elastic metal sheet. The front and rear sides of the right end of the inner wall of the V-shaped elastic metal sheet are fixedly connected to fixed seats 2. The tops of the two fixed seats 1 and the two fixed seats 2 are fixedly connected to positioning rods. The top of the two fixed seats 1 is provided with filter screen 1. The right side of the inner wall of filter screen 1 is slidably connected to filter screen 2. The bottom of filter screen 1 and filter screen 2 are provided with two positioning holes. The multiple positioning holes are respectively engaged with the corresponding positioning rods.

[0009] Through the above technical solution: two fixing seats are firmly fixed to the front and rear sides of the left end of the inner wall of the V-shaped elastic metal sheet, respectively, while fixing seat two is correspondingly fixed to the front and rear sides of the right end of the inner wall of the V-shaped elastic metal sheet. Their function is to provide stable support for the entire filter structure and ensure that the filter mechanism is tightly connected to the V-shaped elastic metal sheet. Both fixing seats one and two are equipped with positioning rods at the top. These positioning rods engage with the positioning holes at the bottom of filter screen one and filter screen two. This engagement structure plays a precise positioning role, so that the filter screen can remain stable after installation and prevent displacement under the impact of water flow. Filter screen one is set on the top of fixing seat one, and its inner right side is slidably connected to filter screen two. The two work together to filter the water entering the V-shaped elastic metal sheet and effectively block impurities. In addition, this sliding connection method, combined with the cooperation of the positioning rods, allows the filter screen to adjust its position according to the deformation of the V-shaped elastic metal sheet, ensuring effective filtration under various working conditions, maintaining smooth drainage and overall performance of the waterproof structure.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the V-shaped elastic metal sheet is fixedly connected to two connecting plates on both the front and rear sides, and the inner walls of the two connecting plates on the front side are threaded with bolts.

[0012] The above technical solution involves connecting plates on the front and rear sides of the inner wall of the V-shaped elastic metal sheet. The connecting plates are threadedly connected to bolts, thereby allowing other V-shaped elastic metal sheets to be connected.

[0013] As a further description of the above technical solution:

[0014] A sealing sheet is fixedly connected to the front side of the outer wall of the rubber pad, and the cross-section of the sealing sheet is the same as the cross-sectional dimension of the rubber pad.

[0015] The above technical solution involves a sealing sheet on the front side of the outer wall of the rubber pad, whose cross-section is consistent with that of the rubber pad. When multiple rubber pads are connected, the connection can be sealed to prevent moisture penetration.

[0016] As a further description of the above technical solution:

[0017] Each of the screws has a cross-shaped groove on its top, and the surfaces of the screws are all treated with anti-corrosion measures.

[0018] The above technical solution features a cross-shaped groove on the top of the screw for easy screwdriver operation, and its surface is treated with anti-corrosion measures to extend the screw's lifespan and ensure structural stability.

[0019] As a further description of the above technical solution:

[0020] The rubber pad has multiple drainage grooves on its top left and right sides, and the spacing between adjacent drainage grooves is equal.

[0021] The above technical solution involves equally spaced drainage grooves on the top left and right sides of the rubber pad, which guide rainwater to flow quickly to the V-shaped elastic metal sheet, thereby accelerating drainage.

[0022] As a further description of the above technical solution:

[0023] The top of the rubber pad is inclined, and the height of both sides of the rubber pad is greater than the height of the inner side of the rubber pad.

[0024] The above technical solution involves a sloping top on the rubber pad, which prevents water from lingering on the pad for extended periods, facilitating rapid drainage.

[0025] As a further description of the above technical solution:

[0026] Hexagonal posts are fixedly connected to the outer walls of the multiple rotating sleeves, and the surfaces of the multiple hexagonal posts are all treated with anti-corrosion measures.

[0027] The above technical solution allows the hexagonal column to be easily rotated with tools to adjust the threaded rod pressing the V-shaped elastic metal sheet. Its surface is treated with anti-corrosion to extend its service life and ensure stable adjustment function.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the pointed bottom and elasticity of the V-shaped elastic metal sheet, combined with the threaded connection between the rotating sleeve and the threaded rod, enable easy installation and ensure that the rubber pad fits tightly against the wall. The straight plate assists in enhancing the seal, and the rubber pad is further compressed by the screw to achieve a double seal. This solves the problem of complex operation in the prior art. At the same time, the V-shaped structure of the V-shaped elastic metal sheet can drain water quickly, preventing rainwater from corroding the sealing components. This improves the problem of poor waterproofing effect due to excessive water volume and untimely drainage, and enhances the durability and reliability of waterproofing.

[0030] 2. In this utility model, filter screen one and filter screen two are set on the upper part of the inner wall of the V-shaped elastic metal sheet. The two fit together tightly to effectively filter the water entering the V-shaped elastic metal sheet, block impurities, ensure smooth drainage, avoid damage to the sealing components due to impurities, and ensure the normal operation of the waterproof structure. At the same time, filter screen one is slidably connected to the positioning rod. The positioning rod engages with the positioning hole, so that filter screen one can slide with the opening and closing size of the V-shaped elastic metal sheet and adapt to its different degrees of deformation.

[0039] 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.

[0040] Reference Figure 1 , Figure 2 and Figure 6This utility model provides an embodiment of a waterproof structure for construction joints, including a V-shaped elastic metal sheet 1 as the main support structure. Its V-shaped design facilitates insertion into the construction joint and guides drainage. A rubber pad 3 is fixedly connected to the outer wall of the V-shaped elastic metal sheet 1 to enhance the seal with the walls on both sides of the construction joint and prevent water penetration. Straight plates 4 are provided on both the left and right sides of the inner interior of the rubber pad 3 to help the rubber pad 3 fit more tightly against the wall under pressure, strengthening the sealing effect. Multiple rotating sleeves 5 are provided on both the front and rear sides of the inner interior of the V-shaped elastic metal sheet 1 to adjust the position of threaded rods 6, thereby adjusting the degree of compression of the V-shaped elastic metal sheet 1. Threaded rods 6 are threadedly connected to the left and right sides of the inner walls of the multiple rotating sleeves 5. The threaded rods 6 engage with the rotating sleeves 5 through threaded contact to achieve… The V-shaped elastic metal sheet 1 is now moved to both sides to compress it. The ends of multiple threaded rods 6 are fixedly connected to the V-shaped elastic metal sheet 1, so that the movement of the threaded rods 6 can effectively compress the V-shaped elastic metal sheet 1. Multiple screws 7 are threaded on the top left and right sides of the rubber pad 3 to further fix the rubber pad 3 to the wall and enhance the sealing performance. The bottom ends of the multiple screws 7 penetrate the corresponding straight plate 4 and rubber pad 3. By penetrating the straight plate 4 and rubber pad 3, the screws 7 can apply pressure to the straight plate 4 and rubber pad 3 to improve the sealing effect. Water-blocking strips 8 are provided on the left and right sides of the outer wall of the rubber pad 3 to further prevent water from seeping from both sides of the rubber pad 3 and enhance the waterproof ability. A filter mechanism 2 is provided on the inner wall of the V-shaped elastic metal sheet 1.

[0041] Specifically, the V-shaped elastic metal sheet 1 forms the basic framework of the entire structure. Its V-shaped design not only facilitates insertion into the construction joint but also effectively drains water, preventing rainwater accumulation and corrosion of the sealing components. The rubber gasket 3, fixedly connected to its outer wall, enhances the fit with the walls on both sides of the construction joint, improving the sealing effect. The straight plates 4 on the left and right sides inside the rubber gasket 3, with a 90-degree included angle in the middle, help the rubber gasket 3 adhere more tightly to the wall when compressed. Simultaneously, during the tightening of the screws 7, the straight plates 4 are compressed, further ensuring a tight fit between the bottom of the rubber gasket 3 and the wall, achieving a double seal. The internal structure of the V-shaped elastic metal sheet 1... Multiple rotating sleeves 5 on the front and rear sides work in conjunction with threaded rods 6 connected to the left and right sides of the inner wall. When rotating the rotating sleeves 5, the threaded rods 6 move to both sides, squeezing the left and right sides of the V-shaped elastic metal sheet 1, thereby making the rubber pad 3 tightly adhere to the walls on both sides. The sealing force can be flexibly adjusted according to the actual situation of the construction joint. Multiple screws 7 connected to the left and right sides of the top of the rubber pad 3 penetrate the straight plate 4 and the rubber pad 3. During the tightening process, they squeeze the straight plate 4, indirectly making the rubber pad 3 fit more tightly to the wall and enhancing the sealing effect. The water-blocking strips 8 set on the left and right sides of the outer wall of the rubber pad 3 further prevent water from seeping from the side and enhance the waterproof performance.

[0042] Reference Figure 1 , Figure 2 and Figure 5The filter mechanism 2 includes two fixed seats 201. The left sides of the two fixed seats 201 are respectively fixedly connected to the front and rear sides of the left end of the inner wall of the V-shaped elastic metal sheet 1, providing an installation base for the filter screen 204 and connecting it to the left end of the inner wall of the V-shaped elastic metal sheet 1. Fixed seats 202 are fixedly connected to the front and rear sides of the right end of the inner wall of the V-shaped elastic metal sheet 1. Positioning rods 203 are fixedly connected to the top of the two fixed seats 201 and the two fixed seats 202. The positioning rods 203 serve to position the filter screen 204 and the filter screen 205, ensuring their installation. The installation position is accurate. The top of the two fixed bases 201 is equipped with a filter screen 204, which is responsible for filtering the water entering the V-shaped elastic metal sheet 1 and blocking larger particles of debris. The inner wall of the filter screen 204 is slidably connected to the filter screen 205. The bottom of both the filter screen 204 and the filter screen 205 has two positioning holes 206. The positioning holes 206 are used to cooperate with the positioning rods 203 so that the filter screen 204 and the filter screen 205 can be stably installed in a fixed position. The multiple positioning holes 206 are respectively engaged with the corresponding positioning rods 203.

[0043] Specifically, two fixing seats 1 201 are fixed to the front and rear sides of the left end of the inner wall of the V-shaped elastic metal sheet 1, and fixing seat 2 202 is fixed to the front and rear sides of the right end of the inner wall of the V-shaped elastic metal sheet 1. They provide stable support for the entire filter structure, ensuring that the filter mechanism 2 is tightly connected to the V-shaped elastic metal sheet 1. The positioning rods 203 at the top of fixing seats 1 201 and 202 engage with the positioning holes 206 at the bottom of filter screens 1 204 and 205, playing a positioning role, so that the filter screens are stably installed and prevented from shifting under the impact of water flow. Filter screen 1 204 is set on the top of fixing seat 1 201, and its inner right side is slidably connected to filter screen 205. The two work together to filter the water entering the V-shaped elastic metal sheet 1 and block impurities. At the same time, this sliding connection method and the cooperation with the positioning rods 203 allow the filter screens to adjust their position according to the deformation of the V-shaped elastic metal sheet 1, ensuring effective filtration under different working conditions and maintaining the smooth drainage and overall performance of the waterproof structure.

[0044] Reference Figure 1 , Figure 3 and Figure 4Two connecting plates 9 are fixedly connected to the front and rear sides of the inner wall of the V-shaped elastic metal sheet 1. Bolts 10 are threadedly connected to the inner walls of the two front connecting plates 9. The connecting plates 9 on the front and rear sides of the inner wall of the V-shaped elastic metal sheet 1 can be used to connect other V-shaped elastic metal sheets 1 through the bolts 10 threadedly connected to them. A sealing plate 11 is fixedly connected to the front side of the outer wall of the rubber pad 3. The cross-section of the sealing plate 11 is the same as the cross-section of the rubber pad 3. Because the cross-section of the sealing plate 11 on the front side of the outer wall of the rubber pad 3 is the same as that of the rubber pad 3, it can ensure the sealing of the connection and prevent water penetration when multiple rubber pads 3 are connected. A cross groove 12 is opened on the top of multiple screws 7. The surface of multiple screws 7 is treated with anti-corrosion. The cross groove 12 on the top of the screw 7 is easy to operate with a screwdriver. The anti-corrosion treatment on its surface extends the service life of the screw 7 and ensures the structural stability.

[0045] Specifically, the connecting plates 9 on the front and rear sides of the inner wall of the V-shaped elastic metal sheet 1, connected to it by bolts 10, can be used to connect other V-shaped elastic metal sheets 1. The sealing plate 11 on the front side of the outer wall of the rubber pad 3, because its cross-section is consistent with that of the rubber pad 3, can ensure the sealing of the connection when multiple rubber pads 3 are connected, preventing water penetration. The cross groove 12 on the top of the screw 7 is easy to operate with a screwdriver, and its anti-corrosion treatment extends the service life of the screw 7 and ensures structural stability.

[0046] Reference Figure 1 , Figure 2 and Figure 6 Multiple drainage grooves 13 are provided on the top left and right sides of the rubber pad 3. The spacing between adjacent drainage grooves 13 is equal, which can guide rainwater to flow quickly to the V-shaped elastic metal sheet 1 and accelerate drainage. The top of the rubber pad 3 is inclined, and the height of the two sides of the rubber pad 3 is greater than the height of the inner side of the rubber pad 3, so as to prevent water from staying on the rubber pad 3 for a long time. Hexagonal columns 14 are fixedly connected to the outer walls of multiple rotating sleeves 5, which makes it convenient to use tools to rotate the rotating sleeves 5. The surfaces of multiple hexagonal columns 14 are all treated with anti-corrosion.

[0047] Specifically, the equally spaced drainage grooves 13 on the left and right sides of the top of the rubber pad 3 can guide rainwater to flow quickly to the V-shaped elastic metal sheet 1, accelerating drainage. The top of the rubber pad 3 is inclined, which can prevent water from staying on the rubber pad 3 for a long time. The hexagonal column 14 makes it easy to use tools to rotate the rotating sleeve 5, thereby adjusting the threaded rod 6 to squeeze the V-shaped elastic metal sheet 1. Its surface anti-corrosion treatment can extend its service life and ensure long-term stability of the adjustment function.

[0048] Working principle: During installation, the operator picks up the device, aligns the bottom of the V-shaped elastic metal sheet 1 with the construction joint gap, and then presses the device down. Because the V-shaped elastic metal sheet 1 is elastic and has a pointed bottom, it can be easily inserted into the gap. After the V-shaped elastic metal sheet 1 and the rubber pad 3 are successfully inserted into the gap, the multiple rotating sleeves 5 are rotated. Since the inner wall of the rotating sleeve 5 is threadedly connected to the threaded rod 6, when the rotating sleeve 5 rotates, it will drive the threaded rod 6 on the inner wall to move to both sides. The threaded rod 6 is also threadedly connected to the V-shaped elastic metal sheet 1. Therefore, when the threaded rod 6 moves to both sides, it will squeeze the left and right sides of the V-shaped elastic metal sheet 1, thereby making the rubber pad 3 on the outside of the V-shaped elastic metal sheet 1 tightly adhere to the two side walls. The included angle of the straight plate 4 inside the rubber pad 3 is 90 degrees. The V-shaped elastic metal sheet 1 squeezes the rubber pad 3. At the same time, the straight plate 4 can help press the outer rubber pad 3, making it fit more tightly against the wall. After the rubber pad 3 is initially attached to the wall, multiple screws 7 are tightened and inserted into the corresponding wall. During the tightening of the screws 7, the screws 7 will squeeze the straight plate 4. Since the straight plate 4 is a high-hardness straight plate 4, after being squeezed by the screws 7, it will further squeeze the outer rubber pad 3, making the bottom of the rubber pad 3 fit more tightly against the wall, achieving a double sealing effect and enhancing waterproof performance. In addition, the V-shaped elastic metal sheet 1 plays an important role in drainage. When there is rain, the V-shaped structure can guide the water flow to drain quickly, avoiding rainwater from accumulating at the construction joint for a long time, thereby effectively preventing rainwater from corroding the sealing components, extending the service life of the waterproof structure, and ensuring the durability of the waterproof effect.

[0049] Furthermore, filter screen 1 204 and filter screen 2 205 are located on the upper part of the inner wall of the V-shaped elastic metal sheet 1. When water enters the V-shaped elastic metal sheet 1, they can effectively filter the water, prevent impurities from entering, ensure smooth drainage, and prevent the sealing components from being damaged by impurities. In addition, since filter screen 1 204 is slidably connected to the positioning rod 203, and the positioning rod 203 engages with the corresponding positioning hole 206, filter screen 1 204 can slide on the positioning rod 203, thereby adjusting accordingly to the opening and closing size of the V-shaped elastic metal sheet 1, adapting to different degrees of deformation of the V-shaped elastic metal sheet 1, and ensuring that a good filtration effect can be maintained under various conditions.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
