Description

Technical Field

[0001] This application relates to the field of waterproofing technology for high-rise buildings, and in particular to a waterproofing structure for high-rise buildings. Background Technology

[0002] During building construction, some exterior wall sections are typically constructed using on-site casting. The process involves erecting and supporting formwork on-site, using tie rods to secure the formwork and ensure its stability. A steel mesh is then installed inside the formwork. Next, concrete is poured into the inner area of ​​the formwork. After the concrete has hardened, the formwork and tie rods are removed.

[0003] After the tie rods are removed, many tie rod holes are left on the exterior wall, which are often sealed with concrete. However, this method of sealing the tie rod holes results in relatively poor waterproofing, allowing water from outside the wall to easily seep into the interior when the exterior wall is exposed to rain, thus reducing the overall performance of the exterior wall. Summary of the Invention

[0004] In order to improve the seepage prevention effect at the screw hole and enhance the performance of the building's exterior wall, this application provides a seepage prevention structure for high-rise buildings.

[0005] This application provides a high-rise building waterproofing structure using the following technical solution:

[0006] A high-rise building anti-seepage structure includes an outer wall with screw holes and a concrete layer for sealing the screw holes. A stepped cavity is opened at one end of the screw hole, and a water baffle is laid in the stepped cavity. The water baffle covers the screw hole, and the concrete layer fills the screw hole and the stepped cavity.

[0007] By adopting the above technical solution, during installation, the baffle plate is installed first, and then the concrete is filled to seal the bolt hole. In the process of use, the baffle plate acts as a water barrier for the bolt hole, reducing the possibility of water seeping into the room from the bolt hole, improving the anti-seepage effect of the building wall at the bolt hole, and improving the service effect of the building exterior wall.

[0008] Optionally, the baffle plate has an installation cavity on the side facing the screw hole, and a water-absorbing block is embedded in the installation cavity, which covers the screw hole. The bottom of the installation cavity is connected to a drain pipe.

[0009] By adopting the above technical solution, when some water seeps into the room from the screw hole, the water will be absorbed by the absorbent block after it approaches the baffle plate, reducing the possibility of water continuing to seep into the room through the baffle plate; and if the absorbent block absorbs a lot of water, some water will gather downwards and be discharged from the drain pipe at the bottom of the installation cavity, reducing the possibility of water overflow, thereby further ensuring the seepage prevention effect.

[0010] Optionally, the bottom wall of the mounting cavity is inclined, and the drain pipe is connected to the lower end of the inclined structure on the mounting cavity. The bottom of the water-absorbing block protrudes towards the drain pipe and has a gathering part.

[0011] By adopting the above technical solution, the bottom of the installation cavity is set as an inclined structure, which is conducive to the timely discharge of water from the installation cavity; and, the bottom of the water-absorbing block is set with a gathering part, so that when the water inside the water-absorbing block falls due to gravity, the water will gather into water droplets in the gathering part, which will facilitate the separation of water from the water-absorbing block, thereby facilitating the discharge of water and further improving the use effect.

[0012] Optionally, the baffle plate is fixed with a protective plate, which abuts against the side of the water-absorbing block away from the baffle plate and passes through the screw hole.

[0013] By adopting the above technical solution, the protective plate provides protection for the water-absorbing block, thereby blocking the concrete layer during filling and reducing the possibility of interference from the concrete layer to the water-absorbing block. At the same time, the protective plate provides better support for the concrete layer, making the concrete layer more stable when filled into the screw hole.

[0014] Optionally, the protective plate is fixed with multiple support columns, which are distributed along the edge of the protective plate and inserted into the water-absorbing block.

[0015] By adopting the above technical solution, when the water-absorbing block is used, the supporting column provides support for the water-absorbing block, so that the water-absorbing block maintains a better unfolding effect, and the water-absorbing block can more fully absorb the water that seeps into the screw hole, thus ensuring better use effect.

[0016] Optionally, the drain pipe has a dual channel inside, and a fan is connected to the drain pipe. The air outlet of the fan is connected to one of the channels inside the drain pipe.

[0017] By adopting the above technical solution, when in use, the fan is turned on, and air is blown into one of the channels in the drain pipe. The airflow can blow onto the water-absorbing block in the installation cavity and dry the water-absorbing block, so that the water-absorbing block has a better water absorption effect when used later. In addition, during the drying process, the other channel in the drain pipe facilitates the airflow in the installation cavity, making the drying effect of the water-absorbing block even better.

[0018] Optionally, the air outlet end of the fan is covered with a sealing plate, which is elastically hinged to the inner wall of the drain pipe, so that the sealing plate has a tendency to automatically rotate toward the inside of the drain pipe, and the drain pipe is provided with a control component for controlling the sealing plate to close the air outlet end of the fan.

[0019] By adopting the above technical solution, the sealing plate can be rotated by the control component, thereby controlling the sealing plate to open or close the air outlet of the fan. As a result, when water flows in the drain pipe, water is less likely to enter the fan, reducing the impact on the fan.

[0020] Optionally, the control component includes a button and a traction rope. The button is used to control the start and stop of the fan, and one end of the traction rope is connected to the pressing part of the button, and the other end is connected to the sealing plate.

[0021] By adopting the above technical solution, when the button is pressed to control the fan to start, the button can release the traction of the traction rope, and then the sealing plate can automatically rotate towards the drain pipe, releasing the sealing effect on the air outlet of the fan, so that the airflow can blow normally into the drain pipe; when the button is pressed again to turn off the fan, the button can pull the sealing plate through the traction rope, thereby sealing the air outlet of the fan.

[0022] Optionally, a filling groove is provided at the end of the screw hole away from the stepped cavity, and the filling groove is filled with a sealant layer.

[0023] By adopting the above technical solution, the sealant layer has a better sealing effect on the gap between the side wall of the screw hole 11 and the concrete layer, thereby improving the seepage prevention effect at the screw hole.

[0024] Optionally, a reinforcing frame is installed in the filling groove. The reinforcing frame is embedded in the sealant layer. The reinforcing frame is fixed with a connecting rod inserted into the concrete layer. The reinforcing frame has an avoidance notch at the part corresponding to the gap between the inner wall of the screw hole and the concrete layer.

[0025] By adopting the above technical solution, the connecting rod is pre-embedded in the concrete layer during filling, and then the reinforcing frame is fixed to the connecting rod. The sealant layer is then filled into the filling groove, resulting in a better sealing effect on the gap between the screw hole sidewall and the concrete layer. Furthermore, the reinforcing frame provides better support for the sealant layer, making it more stable during application. The avoidance notch also allows the sealant layer to properly cover the gap between the screw hole sidewall and the concrete layer, ensuring excellent sealing and seepage prevention.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. During installation, the water baffle plate acts as a barrier against moisture in the screw holes, reducing the possibility of moisture seeping into the room from the screw holes, improving the waterproofing effect of the building wall at the screw holes, and enhancing the usability of the building's exterior walls;

[0028] 2. If some water seeps into the room from the screw hole, the water will be absorbed by the absorbent block, reducing the possibility of water continuing to seep into the room through the baffle plate; in addition, some water inside the absorbent block will gather downwards and be discharged from the drain pipe at the bottom of the installation cavity, reducing the possibility of water overflow, thereby further ensuring the seepage prevention effect.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a waterproofing structure for high-rise buildings. (Refer to...) Figure 1 The high-rise building's waterproofing structure includes an exterior wall 1 with bolt holes 11 and a concrete layer 2. A stepped cavity 12 is formed at the interior end of the bolt hole 11, and a water-blocking plate 3 is laid inside the stepped cavity 12, covering the bolt hole 11. The concrete layer 2 fills the bolt hole 11 and the stepped cavity 12, thus embedding the water-blocking plate 3 within the concrete layer 2.

[0037] During installation, the baffle plate 3 is installed first, followed by concrete filling to seal the bolt hole 11. Then, during use, the baffle plate 3 acts as a moisture barrier for the bolt hole 11, reducing the possibility of moisture seeping into the room from within the bolt hole 11, improving the waterproofing effect of the building wall at the bolt hole 11, and enhancing the overall performance of the building's exterior wall.

[0038] Reference Figure 2 and Figure 3 At this time, the water baffle 3 has an installation cavity 31 on the side facing the screw hole 11, and the installation cavity 31 is set with its opening facing the screw hole 11. A water-absorbing block 4 is embedded in the installation cavity 31. The water-absorbing block 4 is made of water-absorbing sponge and covers the screw hole 11. The bottom of the installation cavity 31 is connected to a drain pipe 5. A water collection tank can be set at the end of the drain pipe 5 away from the installation cavity 31, or the end of the drain pipe 5 away from the installation cavity 31 can be connected to the building drainage channel.

[0039] Reference Figure 2 and Figure 3 Meanwhile, the bottom wall of the mounting cavity 31 has an inclined structure, and the drain pipe 5 is connected to the lower end of the inclined structure at the bottom of the mounting cavity 31. In addition, the bottom of the water-absorbing block 4 has a downward protruding gathering part 41, which faces the water outlet at the bottom of the mounting cavity 31.

[0040] During use, if some moisture seeps into the room from the screw hole 11, the moisture will be absorbed by the absorbent block 4 as it approaches the baffle plate 3, reducing the possibility of moisture continuing to seep into the room through the baffle plate 3. Furthermore, if the absorbent block 4 absorbs a large amount of moisture, some of the moisture will gather downwards and be discharged from the drain pipe 5 at the bottom of the mounting cavity 31, reducing the possibility of moisture overflow and further ensuring the seepage prevention effect.

[0041] In addition, the bottom of the mounting cavity 31 is designed with an inclined structure, which facilitates the timely drainage of water from the mounting cavity 31. Furthermore, the bottom of the absorbent block 4 is provided with a gathering part 41, which allows water inside the absorbent block 4 to gather into water droplets when falling due to gravity. This facilitates the separation of water from the absorbent block 4, thereby making it easier to drain the water and further improving the performance.

[0042] Reference Figure 3 The baffle plate 3 is equipped with a protective plate 32, which abuts against the side of the absorbent block 4 away from the bottom wall of the mounting cavity 31. The protective plate 32 passes through the screw hole 11 and abuts against the inner wall of the screw hole 11. A connecting post is fixed to the protective plate 32, and the connecting post passes through the absorbent block 4 and is fixed to the baffle plate 3.

[0043] During installation, the protective plate 32 protects the absorbent block 4, thus blocking the concrete layer 2 during filling and reducing the possibility of interference between the absorbent block 4 and the concrete layer 2. Simultaneously, the protective plate 32 provides better support for the concrete layer 2, resulting in greater stability when the concrete layer 2 is filled within the screw hole 11. Furthermore, the protective plate 32, located within the screw hole 11, also provides some barrier against moisture.

[0044] Reference Figure 3 The protective plate 32 is fixed with multiple support columns 321, which are distributed along the edge of the protective plate 32 and are all inserted into the water-absorbing block 4. Therefore, when the water-absorbing block 4 is in use, the support columns 321 provide support, ensuring the water-absorbing block 4 maintains a good unfolding effect and allows for more comprehensive absorption of water seeping into the screw hole 11, thus ensuring optimal performance.

[0045] Reference Figure 3 and Figure 4 The drain pipe 5 has a dual-channel structure, and both channels are connected to the installation cavity 31. The drain pipe 5 is connected to a fan 6, which is embedded in the outer wall 1. The air outlet of the fan 6 is connected to one of the channels inside the drain pipe 5.

[0046] Reference Figure 4 The air outlet of the blower 6 is covered with a sealing plate 61, which is elastically hinged to the inner wall of the drain pipe 5. The hinge part of the sealing plate 61 is located on the side of the blower 6's air outlet away from the mounting cavity 31. In actual installation, a torsion spring can be installed at the hinge part of the sealing plate 61, or the sealing plate 61 can be set as an elastic lever, so that the movable end of the sealing plate 61 has a tendency to rotate towards the channel of the drain pipe 5. At this time, the drain pipe 5 is equipped with a control component 62, which includes a button 621 and a traction rope 622. The button 621 is electrically connected to the blower 6, so that pressing the button 621 can control the blower 6 to start and stop. One end of the traction rope 622 is connected to the movable end of the sealing plate 61, and the other end is connected to the pressing part of the button 621.

[0047] In use, pressing button 621 turns on fan 6, which blows air into one of the channels in drain pipe 5. The airflow blows onto the absorbent block 4 in mounting cavity 31 and dries it, ensuring better water absorption for subsequent use. Furthermore, during the drying process, the other channel in drain pipe 5 facilitates airflow within mounting cavity 31, further enhancing the drying effect of absorbent block 4.

[0048] In addition, pressing button 621 releases the traction of the traction rope 622, allowing the sealing plate 61 to automatically rotate towards the drain pipe 5, thus releasing the sealing effect on the air outlet of the fan 6 and allowing the airflow to blow normally into the drain pipe 5. Furthermore, after the sealing plate 61 is opened, it also guides the airflow, allowing the airflow to blow more stably into the mounting cavity 31, improving the performance.

[0049] When button 621 is pressed again to turn off the fan 6, button 621 can pull the sealing plate 61 through the traction rope 622 to close the air outlet of the fan 6. As a result, when water flows in the drain pipe 5 later, water is less likely to enter the fan 6, reducing the impact on the fan 6.

[0050] Reference Figure 2 and Figure 5 A filling groove 111 is provided at the end of the screw eye 11 away from the stepped cavity 12, and the filling groove 111 is filled with a sealant layer 7.

[0051] Reference Figure 5 In addition, a reinforcing frame 71 is installed in the filling groove 111. The reinforcing frame 71 is equipped with a connecting rod 72, which is anchored in the concrete layer 2. The reinforcing frame 71 is fixed to the connecting rod 72 by bolts. The reinforcing frame 71 has an avoidance notch 711 at the part of the gap between the side wall of the screw hole 11 and the concrete layer 2.

[0052] During installation, after the concrete layer 2 is filled, the reinforcing frame 71 is fixed to the connecting rod 72. Then, the sealant layer 7 is filled into the filling groove 111, thereby providing a better seal between the sealant layer 7 and the gap between the screw hole 11 sidewall and the concrete layer 2. Furthermore, the reinforcing frame 71 provides better support for the sealant layer 7, making its application more stable. The clearance notch 711 also allows the sealant layer 7 to properly cover the gap between the screw hole 11 sidewall and the concrete layer 2, ensuring a better sealing and seepage prevention effect.

[0053] In actual construction, a finishing layer can be installed on the exterior of exterior wall 1 to further improve the waterproofing effect of exterior wall 1 and also enhance the aesthetic appeal.

[0054] The implementation principle of the anti-seepage structure for high-rise buildings in this application embodiment is as follows: During use, if some water seeps into the room from the screw hole 11, the water will be absorbed by the absorbent block 4 after approaching the baffle plate 3, reducing the possibility of water continuing to seep into the room through the baffle plate 3. Furthermore, if the absorbent block 4 absorbs a large amount of water, some of the water will accumulate downwards and be discharged from the drain pipe 5 at the bottom of the installation cavity 31, thereby reducing the possibility of water seeping into the room from the screw hole 11, improving the anti-seepage effect of the building wall at the screw hole 11, and enhancing the usability of the building's exterior wall.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
