Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a waterproof structure for building engineering. Background Technology

[0002] In the construction of building roof expansion joints, the waterproof structure first needs to fill the expansion joint with sealant, then lay synthetic polymer rolls on the expansion joint, making the synthetic polymer rolls 2 cm recessed at the expansion joint, then lay foam strips in the recessed area, then lay another layer of polymer rolls, and finally cover it with fine stone concrete or stainless steel cover plates.

[0003] A search revealed a patent document with publication number "CN221118814U" that discloses a waterproof structure for roof expansion joints. This structure includes waterstops on both sides of the expansion joint, two bottom connecting components on both sides of the expansion joint, a central self-adjusting connecting component on the two bottom connecting components, and a top waterproof component on the central self-adjusting connecting component. The central self-adjusting connecting component includes two connecting plates on the two bottom connecting components and sliding plates that are slidably connected to the two connecting plates on both sides. The top waterproof component includes multiple long screws vertically mounted on the sliding plates and cover plates mounted on the multiple long screws.

[0004] In addition, patent document with announcement number "CN222390665U" discloses another roof expansion joint waterproof structure, including a wall, a waterproof structural layer, a cover plate and a cross-shaped connecting rod. The waterproof structural layer is fixedly connected to both ends of the wall, and a base is fixedly connected to the surface of the waterproof structural layer at both ends. The side walls of the bases at both ends are provided with grooves, and multiple sliding plates slide between the grooves. L-shaped positioning plates are fixedly connected to the top of the bases at both ends. The side walls of the L-shaped positioning plates at both ends are slidably connected to the cover plate through a buffer mechanism. Multiple cross-shaped connecting rods are fixedly connected to the top of the cover plate.

[0005] Based on the above research and existing technology, it was found that the existing waterproof structures mainly rely on flexible sealing strips to seal the cover plate and the lower support. However, when the expansion joint deforms, friction occurs between the two, which may lead to fatigue damage and reduced sealing effect after long-term use. In addition, existing cover plates are usually fixed with bolts. Since the roof expansion joint structure is long (for example, the length of the expansion joint in the roof of a residential building is usually more than 10m, and the longer the expansion joint, the larger the roof width, the greater the length of the expansion joint), the workload of bolting the cover plate is large, and leakage is prone to occur at the bolt holes, which reduces the waterproof life of the cover plate. If water is concentrated inside, it will cause the entire waterproof structure to deteriorate faster and lose its waterproof function. Therefore, a new waterproof structure for building engineering is needed. Utility Model Content

[0006] The purpose of this application is to provide a waterproof structure for building engineering to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a waterproof structure for building engineering, including a waterstop strip laid in the roof expansion joint, with Z-shaped hanging plates overlapping on both sides of the waterstop strip, and a gap between the two Z-shaped hanging plates.

[0008] Both Z-shaped mounting plates are fitted with seals on their upper parts, which are far apart from each other. The seals are elastic.

[0009] A cover plate is engaged between the upper outer sides of the two Z-shaped hanging plates. A hanging strip is fixed to the bottom inner side of the cover plate and abuts against the sealing element. The upper part of the hanging strip abuts against the lower part of the sealing element and forms a seal.

[0010] A fourth sealing strip is also fixed to the inside of the cover plate. The fourth sealing strip abuts against the middle of the sealing element to form a seal.

[0011] As a further supplement to this solution, the sealing element includes a second sealing strip and a third sealing strip, with the second sealing strip located below the third sealing strip, and the second sealing strip and the third sealing strip being fixedly connected;

[0012] The lower end of the second sealing strip abuts against the upper end of the hanging strip with an interference fit, and the middle parts of the third sealing strip and the second sealing strip, which are close to each other, abut against the fourth sealing strip with an interference fit.

[0013] As a further supplement to this solution, abutment plates are fixed to one side of both the second and third sealing strips, and the abutment plates are fixed to the outside of the Z-shaped hanging plate by a clamping spring.

[0014] As a further supplement to this solution, the upper horizontal part of the Z-shaped hanging plate is integrally formed with a limiting rib, the bottom of the second sealing strip is pressed against the limiting rib, and the front end of the hanging strip is pressed against one side of the limiting rib.

[0015] As a further supplement to this solution, a fixing notch is provided on the inner side of the lower part of the Z-shaped hanging plate, and a first sealing strip is fixedly embedded in the fixing notch. The top of the first sealing strip is pressed against the lower end of the waterstop, and one side of the first sealing strip is pressed against the wall of the roof expansion joint.

[0016] As a further supplement to this solution, each of the two Z-shaped mounting plates has a slot on the side that is close to each other. The upper end of the slot is open, and a locking block is slidably engaged in the slot. The two locking blocks are elastically connected by a tension spring.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, the use of two Z-shaped hanging plates, a cover plate, and sealing elements eliminates the need for bolts and other structures, thus accelerating construction efficiency and avoiding potential leakage problems that may occur with bolted structures. This improves the overall waterproof performance of the building's waterproof structure. Furthermore, the installed hanging strips, fourth sealing strips, and sealing elements work together to form a double sealing structure. The sealing structure is a compression seal, meaning that when the roof expansion joint deforms, the fourth sealing strip and sealing elements compress against each other rather than rub against each other, reducing fatigue damage caused by deformation and extending the service life of the sealing elements. This ensures that the building's waterproof structure maintains good sealing performance even after long-term use, further enhancing the waterproof effect.

[0019] 2. In this utility model, by using a stop plate in conjunction with a clamping spring, even if the second and third sealing strips experience fatigue deformation during long-term use, the stop plate can still force the second and third sealing strips to abut against the hanging strip and the fourth sealing strip under the elastic force of the clamping spring, thus forming a good seal and further improving the stability of the sealing performance of the waterproof structure of the building project after long-term use.

[0020] 3. In this utility model, a tension spring applies a prestress to the two Z-shaped hanging plates to bring them closer together, thereby making the two Z-shaped hanging plates closer to each other. This not only makes the overall integrity of the waterproof structure of the building project stronger, but also makes the connection between the two Z-shaped hanging plates and the roof expansion joint more stable. In addition, it can also pre-connect the two Z-shaped hanging plates before the cover plate is installed, so as to facilitate the insertion and installation of the cover plate.

[0028] 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.

[0029] Example: Reference Figures 1-3 The waterproof structure of a building project shown includes a waterstop 1 laid in the roof expansion joint. Z-shaped hanging plates 2 are overlapped on both sides of the waterstop 1. The Z-shaped hanging plates 2 are horizontally arranged Z-shaped plate structures. Specifically, the Z-shaped hanging plates 2 have two vertical plates and one horizontal plate. The two vertical plates are located at both ends of the horizontal plate and on both sides below. The horizontal plate of the Z-shaped hanging plates 2 is located at the top of the roof expansion joint. One of the vertical plates is located on the outer wall of the roof expansion joint, and the other vertical plate is located above the gap of the roof expansion joint and extends upward. There is a gap between the two Z-shaped hanging plates 2.

[0030] Both Z-shaped mounting plates 2 are equipped with sealing elements 5 on their upper parts, which are far apart from each other. The sealing elements 5 are elastic structures.

[0031] A cover plate 3 is engaged between the upper outer sides of the two Z-shaped hanging plates 2. A hanging strip 31 that abuts against the sealing element 5 is fixed to the bottom inner side of the cover plate 3. The upper part of the hanging strip 31 abuts against the lower part of the sealing element 5 to form a seal.

[0032] A fourth sealing strip 32 is also fixed to the inner side of the cover plate 3. The fourth sealing strip 32 abuts against the middle of the sealing element 5 to form a seal.

[0033] Based on the above structure, during installation, workers only need to lay the waterstop 1 at the roof expansion joint, then place the two Z-shaped hanging plates 2 on both sides of the roof expansion joint, ensuring that the two Z-shaped hanging plates 2 are pressed tightly against the waterstop 1. After that, simply press down the cover plate 3 from above, ensuring that the upper part of the hanging strip 31 abuts against the lower part of the sealing element 5 to complete the installation. The entire installation process is simple to operate and does not require the use of bolts or other structures, which not only speeds up the construction efficiency but also avoids the leakage problems that may be caused by using bolt structures, thus improving the overall waterproof performance of the building's waterproof structure.

[0034] Furthermore, the installed hanging strip 31, the fourth sealing strip 32, and the sealing element 5 work together to form a double sealing structure. Moreover, the sealing structure is a compression seal. When the roof expansion joint deforms (referring to expansion deformation), the fourth sealing strip 32 and the sealing element 5 are squeezed against each other instead of rubbing against each other, reducing fatigue damage caused by deformation and extending the service life of the sealing element 5. This ensures that the waterproof structure of the building project can still have good sealing performance after long-term use, and the waterproof effect is further improved.

[0035] Furthermore, the sealing element 5 includes a second sealing strip 51 and a third sealing strip 52, with the second sealing strip 51 located below the third sealing strip 52, and the second sealing strip 51 and the third sealing strip 52 being fixedly connected.

[0036] The lower end of the second sealing strip 51 abuts against the upper end of the hanging strip 31 with an interference fit, and the middle parts of the third sealing strip 52 and the second sealing strip 51, which are close to each other, abut against the fourth sealing strip 32 with an interference fit.

[0037] Furthermore, abutment plates 6 are fixed to one side of both the second sealing strip 51 and the third sealing strip 52. The abutment plates 6 are fixed to the outer side of the Z-shaped hanging plate 2 by means of a retaining spring 61.

[0038] By using the abutment plate 6 in conjunction with the clamping spring 61, even if the second sealing strip 51 and the third sealing strip 52 experience fatigue deformation during long-term use, the abutment plate 6 can still force the second sealing strip 51 and the third sealing strip 52 to fit tightly against the hanging strip 31 and the fourth sealing strip 32 under the elastic force of the clamping spring 61, thus forming a good seal and further improving the stability of the sealing performance of the waterproof structure of the building project after long-term use.

[0039] Furthermore, the upper horizontal part of the Z-shaped hanging plate 2 is integrally formed with a limiting rib 22, the bottom of the second sealing strip 51 is pressed against the limiting rib 22, and the front end of the hanging strip 31 is pressed against one side of the limiting rib 22. The limiting rib 22 can restrict the position of the hanging strip 31, preventing the hanging strip 31 and the second sealing strip 51 from squeezing each other to create a bottom gap, thereby preventing rainwater from seeping inward from the bottom of the hanging strip 31 and ensuring the effectiveness of the seal.

[0040] Furthermore, a fixing notch 21 is provided on the inner side of the lower part of the Z-shaped hanging plate 2. A first sealing strip 4 is fixedly embedded in the fixing notch 21. The top of the first sealing strip 4 is pressed against the lower end of the waterstop 1, and one side of the first sealing strip 4 is pressed against the wall of the roof expansion joint, providing external sealing protection and thus enhancing the overall sealing effect of the waterproof structure of the building project.

[0041] Figures 4-5 As shown, each of the two Z-shaped hanging plates 2 has a slot 23 on one side that is close to each other. The upper end of the slot 23 is open, and a block 8 is slidably engaged in the slot 23. The two blocks 8 are elastically connected by a tension spring 7.

[0042] By applying prestress to the two Z-shaped hanging plates 2 by the tension spring 7, the two Z-shaped hanging plates 2 are brought closer to each other, which not only makes the overall integrity of the waterproof structure of the building project stronger, but also makes the connection between the two Z-shaped hanging plates 2 and the roof expansion joint more stable. In addition, it can also pre-connect the two Z-shaped hanging plates 2 before the cover plate 3 is installed, so as to facilitate the insertion and installation of the cover plate 3.

[0043] The working principle of this utility model is as follows: In daily use, the workers first need to lay the waterstop 1 at the roof expansion joint, then place two Z-shaped hanging plates 2 on both sides of the roof expansion joint, so that the two Z-shaped hanging plates 2 are pressed against the waterstop 1, and insert the clip 8 into the slot 23 so that the tension spring 7 is pre-connected to the two Z-shaped hanging plates 2. Then, simply press down the cover plate 3 from above, so that the end of the hanging strip 31 is pressed against the limiting rib 22, and the upper part of the hanging strip 31 abuts against the lower part of the second sealing strip 51 to complete the installation. The entire installation process is simple to operate and does not require the use of bolts or other structures, which not only speeds up the construction efficiency, but also avoids the leakage problems that may be caused by the use of bolt structures, and improves the overall waterproof performance of the building waterproof structure.

[0044] Furthermore, the installed hanging strip 31, the fourth sealing strip 32, and the sealing element 5 work together to form a double sealing structure. Moreover, the sealing structure is a compression seal. When the roof expansion joint deforms, the fourth sealing strip 32 and the sealing element 5 are squeezed against each other instead of rubbing against each other, reducing fatigue damage caused by deformation and extending the service life of the sealing element 5. This ensures that the waterproof structure of the building project can still have good sealing performance after long-term use, and the waterproof effect is further improved.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
