Description

Technical Field

[0001] This invention relates to the field of wall waterproofing structure technology, specifically to a method and a waterproofing structure for preventing the corner finishing layer from getting damp and peeling off. Background Technology

[0002] Dampness in the walls is closely related to the absorbency of the basement floor slab and walls, as well as capillary action. Capillary action occurs when liquid rises or falls inside a narrow tube due to the difference between cohesive and adhesive forces, overcoming gravity. The surface of the wetting liquid in the capillary is concave, exerting a pulling force on the liquid below, causing it to rise along the tube wall. When the upward pulling force equals the weight of the liquid column inside the tube, the liquid stops rising, reaching equilibrium. Because the wall bricks and mortar have relatively high porosity, water absorption coefficient, and expansion coefficient, under capillary action, the bricks easily absorb and permeate water from the natural environment. This leads to freeze-thaw weathering, salt crystallization, biological weathering, and mineral dissolution under the influence of temperature and humidity changes, soluble salts, and microorganisms, exacerbating wall weathering and causing various deterioration conditions such as surface powdering, warping, and peeling. The existing solution only involves removing the wall finish down to the structure and applying a new finish, which is a temporary fix and cannot completely solve the problem. Summary of the Invention

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, the present invention provides a method and a waterproof structure for preventing the corner finishing layer from getting damp and peeling off. The method and the waterproof structure for preventing the corner finishing layer from getting damp and peeling off are easy to construct and have low maintenance costs, and can effectively solve the problem of wall finishing layer peeling off due to moisture seepage from the bottom.

[0004] To achieve the above objectives, a first aspect of the present invention provides a method for preventing the corner finishing layer from peeling off due to moisture, wherein the wall includes a wall structural layer and a wall finishing layer, and the ground adjacent to the wall includes a protective layer and a ground structural layer from top to bottom, the method comprising:

[0017] S23. Apply a continuous second waterproof layer over the first waterproof layer in the grooves of the wall finish layer and the ground protection layer, extending up to the top of the water-blocking groove.

[0018] Optionally, the first waterproof layer may be a cement-based waterproof coating, and the second waterproof layer may be a polyurethane waterproof coating.

[0019] Optionally, sealant can be applied to the bottom edges of the water-retaining groove on both sides parallel to the wall base line.

[0020] In some embodiments, the waterproof structure may further include a waterproof additional layer, and S2 further includes: providing the waterproof additional layer at the right angle position between the wall finish layer groove and the ground protection layer groove;

[0021] And / or, the ground adjacent to the wall may be the basement floor, and the wall may be an interior wall of the basement;

[0022] And / or, the ground may also include an existing waterproof structure located beneath the ground structure layer.

[0023] A second aspect of the present invention also provides a waterproof structure for a corner finishing layer, wherein the wall comprises a wall structural layer and a wall finishing layer, and the ground adjacent to the wall comprises a protective layer and a ground structural layer from top to bottom, and the waterproof structure for the corner finishing layer comprises:

[0024] The wall finish groove is formed by chiseling away the wall finish layer down to the wall structure layer;

[0025] The ground protective layer groove is formed by chiseling away the ground protective layer down to the ground structural layer, and communicates with the wall finishing layer groove; and

[0026] The waterproof structure fully covers the bottom surface of the grooves in the wall finish layer and the floor protection layer.

[0027] Furthermore, the waterproof structure may include a waterproof layer applied to the grooves of the wall finish layer and the floor protection layer, the waterproof layer being used to seal the floor structure layer and the wall structure layer.

[0028] Furthermore, the waterproof structure may also include a water-retaining groove for directing water to the drainage system, the water-retaining groove being disposed on the side of the ground protection layer groove away from the wall.

[0029] In addition, the water-blocking groove can be in the shape of a hollow square tube and is provided with water passage holes and water guiding channels. The water passage holes are connected to the water guiding channels and are set away from the wall. The water guiding channels are connected to the drainage system.

[0030] In addition, a filter screen for filtering mud and sand can be provided on the water passage hole.

[0038] Compared to existing technologies that merely redo the finishing layer, the method and waterproof structure for preventing corner finishing layers from becoming damp and peeling, as described in this invention, removes the wall finishing layer and the ground protective layer connected to it, and then continuously re-applies a waterproof layer on the back side. This, along with new water-blocking measures, solves the problem of water leaking from the base plate seeping through the protective layer to the base of the existing wall, causing the corners to become damp and peel off due to capillary action. In other words, it addresses the problem of dampness in the wall finishing layer from the source of the water, effectively preventing repeated dampness issues. Furthermore, the newly implemented water-blocking measures prevent water from leaking from non-repair areas from flowing into repaired areas, even if the leak point cannot be found on the ground. In addition, the method and waterproof structure for preventing corner finishing layers from becoming damp and peeling not only reduce the cost of finding and repairing leaks but also significantly reduce the difficulty of construction for workers, resulting in good time and quality benefits.

[0039] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0055] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0057] In the embodiments of the present invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of the components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0058] like Figure 1 As shown, existing wall structures generally include a wall structural layer 12 and a wall finishing layer 11, while the ground adjacent to the wall includes a protective layer 21 and a ground structural layer 22 from top to bottom. When the wall becomes damp, it can cause surface powdering, peeling, and flaking. In such cases, it is difficult to pinpoint the actual leak point, and usually only the finishing layer is redone, but the problem of wall dampness will recur. Therefore, this invention provides a method for preventing the corner finishing layer from becoming damp and peeling off, and a waterproof structure for the corner finishing layer, which can prevent the erosion of the wall by seeping water even when the ground leak point cannot be found.

[0059] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0060] The first aspect of the present invention provides a method for preventing the corner finishing layer from peeling off due to moisture, such as... Figure 5 As shown, the method includes:

[0061] S1. Remove the wall finishing layer 11 to the wall structural layer 12 to form a wall finishing layer groove 111, and remove the ground protective layer 21 to the ground structural layer 22 that are connected to the wall to form a ground protective layer groove 211 that is connected to the wall finishing layer groove 111.

[0062] S2. A waterproof structure is installed on the wall finish layer groove 111 and the floor protection layer groove 211.

[0063] The method of preventing corner finishing layers from detaching due to moisture in this invention involves removing the wall finishing layer 11 to the wall structural layer 12 and the ground protective layer 21 to the ground structural layer 22, and then continuously reapplying a waterproof layer on the back side. This effectively prevents water leaking from the base plate from seeping through the protective layer on the base plate to the base of the existing wall, and from repeatedly causing the corners to become damp and detach due to capillary action. Because the waterproof layer on the back side of the wall is continuously installed with the waterproof layer on the ground, even if the leakage point on the ground cannot be found, the method of preventing corner finishing layers from detaching due to moisture in this invention can block the erosion of the wall by the leaking water, thus solving the problem of repeated dampness of the wall finishing layer by addressing the source of the water. Furthermore, since the method of preventing corner finishing layers from detaching due to moisture in this invention only requires removing the wall finishing layer 11 and the protective layer 21, without removing the ground structural layer, it not only reduces the cost of finding and repairing leakage points, but also greatly reduces the difficulty of construction for workers, resulting in good time and quality benefits.

[0064] Specifically, in step S1, the surfaces of the wall finishing layer 11 to the wall structural layer 12 are removed, and the surfaces of the ground protective layer 21 to the ground structural layer 22 that are in contact with the wall are also removed. Figure 2 As shown, after chiseling away the wall finish layer 11 downwards at a predetermined height on the wall, a wall finish layer groove 111 is formed. A protective layer 21 is chiseled away from the wall base outwards at a predetermined distance along the ground, forming a ground protective layer groove 211. The bottom of the wall finish layer groove 111 is the surface of the wall structural layer 12, and the bottom of the ground protective layer groove 211 is the surface of the ground structural layer 22. The wall finish layer groove 111 and the ground protective layer groove 211 are connected, thus the waterproof structure in step S2 can form a continuous structure within the wall finish layer groove 111 and the ground protective layer groove 211. After step S1 and before step S2, the bottoms of the wall finish layer groove 111 and the ground protective layer groove 211 can be cleaned, ensuring the bottoms are flat and free of dust. The bottoms can be observed to check for leaks. If leaks are found, they can be repaired and waterproofed before the waterproof structure is installed.

[0065] Furthermore, the waterproof structure may include a waterproof layer, and S2 includes:

[0066] Waterproofing material is applied to the grooves 111 of the wall finish layer and 211 of the floor protection layer to form a connected waterproof layer on the back side of the floor structural layer 22 and the wall structural layer 12.

[0067] like Figure 3 As shown, a special functional back-water pressure waterproof material can be applied to the wall surface layer groove 111 and the ground protective layer groove 211 to seal and waterproof the ground structural layer 22 and the wall structural layer 12.

[0068] Furthermore, the waterproof structure may also include a water-retaining channel 31 for directing water to the drainage system, and S2 may also include:

[0069] A water-retaining groove 31 is installed on the waterproof layer on the side of the ground protective layer groove 211 away from the wall. The water-retaining groove 31 is used to guide water to the drainage system. Figure 3 As shown, the water-blocking groove 31 is set parallel to the baseboard and extends along the extension direction of the baseboard. When a leakage point appears in the groove 211 of the ground protective layer, the leaking water can be discharged to the drainage system through the water-blocking groove 31, thereby preventing the leaking water from seeping into the wall.

[0070] Optionally, S2 may also include:

[0071] A water-guiding channel 312 and a water-passing hole 311 are opened on the side of the water-retaining groove 31 facing away from the wall. The water-guiding channel 312 is connected to the drainage system, and a filter screen capable of filtering mud and sand is installed on the water-passing hole 311. Figure 3 and Figure 4 As shown, the water-blocking channel 31 can be in the shape of a hollow square tube and includes a first sidewall and a second sidewall parallel to the wall. The hollow cavity serves as a water-guiding channel 312. The first sidewall is relatively close to the wall to block water, while the second sidewall is relatively far from the wall and has multiple water-passing holes 311 spaced apart along its extension direction. The water-passing holes 311 communicate with the water-guiding channel 312, allowing leaked water to enter the water-guiding channel 312 through the water-passing holes 311 and be discharged into the drainage system. A filter screen (not shown in the figure) for filtering sediment can be provided on the water-passing holes 311 to prevent sediment from entering the water-guiding channel 312 and the drainage system.

[0072] In some embodiments, such as Figure 6 As shown, the waterproof layer may include a first waterproof layer 32 and a second waterproof layer 33, and S2 includes:

[0073] S21. Apply the first waterproof layer 32 to the grooves of the wall finishing layer and the floor protection layer.

[0074] S22. A water-blocking groove 31 is provided on the first waterproof layer 32 on the side of the ground protective layer groove 211 away from the wall;

[0075] S23. Apply a continuous second waterproof layer 33 to the top of the water-blocking groove 31 on the first waterproof layer 32 in the wall finish groove 111 and the ground protection layer groove 211.

[0076] like Figure 3 As shown, the first waterproof layer 32 and the second waterproof layer 33 are continuously set in the groove of the wall finishing layer and the groove of the ground protection layer, and the water-blocking groove 31 is sandwiched between the first waterproof layer 32 and the second waterproof layer 33. In this way, a waterproof structure with simple structure and reliable waterproof performance is formed.

[0077] Optionally, the first waterproof layer 32 can be a cement-based waterproof coating, and the second waterproof layer 33 can be a polyurethane waterproof coating. The cement-based waterproof coating can be Keshun Company's XS-507 special functional backwater pressure waterproof coating. XS-507 special functional backwater pressure waterproof coating is a composite cement-based waterproof coating composed of high-quality materials such as silicate cement, quartz sand, and special active chemical substances. It has high adhesion and impermeability, and is particularly suitable for waterproofing and leak-stopping on the back side of the surface.

[0078] Optionally, such as Figure 3 As shown, sealant 34 can be applied to the bottom edges of the water-retaining groove 31 on both sides parallel to the wall base line. In this way, by applying sealant 34 to the inside corner of the water-retaining groove 31, the waterproof sealing performance of the waterproof structure can be further enhanced, and the leaked water can be prevented from seeping into the wall through the gap between the water-retaining groove 31 and the first waterproof layer 32.

[0079] Optionally, such as Figure 3 As shown, the waterproof structure may also include a waterproof additional layer 35, and S2 may also include: a waterproof additional layer 35 is provided at the right angle between the wall finish layer groove 111 and the ground protection layer groove 211.

[0080] Optionally, the floor adjacent to the wall is the basement floor, and the wall is the basement interior wall, which typically has a decorative finish. Due to the special location of the basement, it is more prone to water leakage than other buildings; therefore, waterproofing the corner finish is particularly important.

[0081] Optionally, such as Figure 3 As shown, the ground may also include an existing waterproof structure 23 located below the ground structure layer 22 to prevent ground leakage.

[0082] Optionally, the method may further include a step S3 set after S2, wherein step S3 includes:

[0083] The wall finish layer 11 is restored on the waterproof structure in the wall finish layer groove 111, and the ground protection layer 21 is restored on the waterproof structure in the ground protection layer groove 211.

[0084] In this way, the aesthetics of the wall can be restored, and the newly applied wall finish layer 11 will not suffer from the problem of moisture and peeling again.

[0085] A second aspect of the present invention also provides a waterproof structure for a corner finishing layer, such as... Figure 3 As shown, the wall includes a structural layer 12 and a finishing layer 11. The ground adjacent to the wall includes a protective layer 21 and a structural layer 22 from top to bottom. The waterproof structure of the corner finishing layer may include:

[0086] The wall finish layer groove 111 is formed by chiseling away the wall finish layer 11 down to the wall structural layer 12;

[0087] The ground protective layer groove 211 is formed by chiseling away the ground protective layer 21 down to the ground structural layer 22, and communicates with the wall finishing layer groove 111; and

[0088] The waterproof structure fully covers the bottom surface of the grooves 111 in the wall finish layer and 211 in the floor protection layer.

[0089] Furthermore, the waterproof structure may include a waterproof layer applied to the wall finish layer groove 111 and the floor protection layer groove 211, the waterproof layer being used to seal the floor structure layer 22 and the wall structure layer 12.

[0090] It should be noted that the waterproof structure can be a single layer of waterproof coating, or multiple layers such as two or three layers. The bottom layer of the multi-layer waterproof material can be a cement-based waterproof material. When both the front and back of the wall are covered with a wall finish layer, a waterproof structure can be installed on both sides of the front and back of the wall accordingly.

[0091] Furthermore, the waterproof structure also includes a water-retaining channel 31 for directing water to the drainage system, the water-retaining channel 31 being located on the side of the ground protective layer recess 211 away from the wall. For example... Figure 3 and Figure 4 As shown, the water-retaining groove 31 can be in the shape of a hollow square tube and is provided with a water passage hole 311 and a water guiding channel 312. The water passage hole 311 and the water guiding channel 312 are connected and set away from the wall. The water guiding channel 312 is connected to the drainage system. A filter screen for filtering mud and sand is provided on the water passage hole 311. The water-retaining groove 31 is set parallel to the base line and extends along the extension direction of the base line. The extension length of the water-retaining groove 31 corresponds to the length of the wall. In order to further improve the waterproof sealing performance of the waterproof structure, sealant 34 can be provided on the bottom edges of the water-retaining groove 31 on both sides parallel to the base line.

[0092] Optionally, the waterproof layer may include a first waterproof layer 32 and a second waterproof layer 33, with the water-blocking groove 31 sandwiched between the first waterproof layer 32 and the second waterproof layer 33.

[0093] Optionally, the first waterproof layer 32 may be a cement-based waterproof material, and the second waterproof layer 33 may be a polyurethane waterproof coating.

[0094] In some specific embodiments, since the corner of the wall base is a weak point in waterproofing, the waterproof structure may also include a waterproof additional layer 35, which may be set at the right angle between the wall finishing layer groove 111 and the ground protection layer groove 211.

[0095] Optionally, the ground surface in contact with the wall is the basement floor, and the wall is the basement interior wall. The ground surface may also include an existing waterproof structure 23 located below the ground structural layer 22.

[0096] In addition, the waterproof structure of the corner finishing layer also includes a new wall finishing layer 11 and a new protective layer 21. The new wall finishing layer 11 is disposed on the waterproof structure in the wall finishing layer groove 111, and the new protective layer 21 is disposed on the waterproof structure in the ground protective layer groove 211. Figure 3 As shown, a new wall finish layer 11 and a new protective layer 21 are applied to the second waterproof layer 33.

[0097] In summary, the method and waterproof structure for preventing corner finishing layers from becoming damp and peeling, as described in this invention, solves the problem of water seeping from the base plate through the protective layer to the base of the existing wall, causing the corners to become damp and peel off due to capillary action. This is achieved by removing the wall finishing layer and the ground protective layer connected to it, and then continuously re-applying a waterproof layer on the back side and setting up a water-blocking groove. In other words, it addresses the problem of dampness in the wall finishing layer from the source of the water, effectively preventing repeated dampness issues. Furthermore, because the waterproof layer on the back side of the wall is continuously installed with the waterproof layer on the ground, it can prevent water seepage from eroding the wall even if the leak point on the ground cannot be found. In addition, the method and waterproof structure for preventing corner finishing layers from becoming damp and peeling not only reduce the cost of finding and repairing leaks but also significantly reduce the difficulty of construction for workers, resulting in good time and quality benefits.
