[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] This embodiment describes the repair of water-seeping area 7 on the exterior wall of a building. When a water-seeping area appears on the exterior wall (water-seeping area 7 is usually a hollow part), such as Figure 1-6 As shown in Figure 8,

[0036] The present invention provides a building leakage repair process, which involves the following steps:

[0037] S1: Determine the specific location of the building's water seepage zone 7;

[0038] S2: A repair area 10 is set on the seepage area 7, and a first water-stop groove 2 is opened horizontally on the upper edge of the repair area 10. The area of ​​the repair area 10 is larger than the area of ​​the seepage area 7. Furthermore, the repair area 10 is generally 1-2m larger than the seepage area 7 in terms of upward expansion, 0.5-1.5m larger in terms of left and right expansion, and 0.1-0.8m larger in terms of downward expansion. The width × depth of the water-stop groove is generally 50mm × 40mm.

[0039] S3: Install a water-proof strip inside the first water-proof groove 2.

[0040] Specifically, the waterproof strip includes a waterproof strip body 1, which includes a first fixing surface 11 and an inclined surface 12. The angle between the inclined surface 12 and the first fixing surface 11 is set to an acute angle, so that the inclined surface 12 is inclined on one side of the first fixing surface 11. The first fixing surface 11 is fixed to the exterior wall, and the inclined surface 12 is inclined on the exterior wall, so that the leaking water will flow out of the building along the inclined surface 12, preventing the water seepage area of ​​the building from bulging.

[0041] During installation, the first fixing surface 11 is fixed inside the water-proof groove by fasteners 5 (e.g., butyl tape, used for temporary bonding and water-proofing). Water from the water-proof strip body 1 is drained out through the opening of the water-proof groove.

[0042] To ensure that the water-stop strip body 1 is more securely fixed on the water-stop groove, a fastener 14 is also included. The fastener 14 is set as an anchor bolt. The fastener 14 passes through the entire water-stop strip body 1. One end of the fastener 14 is located on the first fixing surface 11, and the other end of the fastener 14 passes through the water-stop groove.

[0043] In order to prevent water from seeping into the fixed position between the water-proof strip body 1 and the fastener 14, a sealing cavity 111 is provided on the first fixing surface 11. The sealing cavity 111 is filled with sealant 6, so that the water-proof strip body 1 is more firmly fixed in the water-proof groove.

[0044] To facilitate the injection of sealant 6 into the sealing cavity 111, the fastener 14 is provided with an injection hole 141, which extends laterally through the fastener 14. The fastener 14 is also provided with a channel 142, which extends vertically from the top of the fastener 14 through the interior of the fastener 14 and communicates with the injection hole 141. The fastener 14 passes through the sealing cavity 111, and the injection hole 141 is located inside the sealing cavity 111, so that the fastener 14 can be injected with grout from the channel 142 through the injection hole 141 into the sealing cavity 111.

[0045] The angle between the inclined plane 11 and the horizontal plane is α, where α is 2°-30°. This slope structure can guide water seepage from the wall to the lower drainage structure, keeping the leaking water away from the building.

[0046] Furthermore, to increase stability, the water-proof strip is also provided with a surface part 16. The surface part 16 is attached to the outer side of the inclined surface 12 and the mounting groove 131 near the inclined surface 12, and the surface part 16 extends to the top of the mounting groove 131, so that the position where the surface part 16 contacts the inclined surface 11 is also set as an inclined surface. The surface part 16 is made of plastic or metal, and the water-proof strip allows water to flow out well.

[0047] The second fixing surface 13 is also provided with a mounting groove 131, and the fastener 14 is fixed in the mounting groove 131.

[0048] To facilitate water guidance in the waterproof strip body 1, a flashing plate 15 is provided in the mounting groove 131. The flashing plate 15 is provided with a mounting platform 151 and a water guiding platform 152. The mounting platform 151 is used to fix the flashing plate 15 in the mounting groove 131, and the water guiding platform 152 extends to the outside of the first fixing surface 11 for water guidance. The flashing plate 15 is made of galvanized iron sheet or aluminum alloy, etc., and can be processed according to the site conditions.

[0049] When only the water guide platform 152 of the water-proof strip body 1 is located outside the water-proof groove, the first fixing surface 11 is located inside the water-proof groove and does not contact the outer layer; when the first fixing surface 11 of the water-proof strip body 1 is located outside the water-proof groove, the surface member 16 on the first fixing surface 11 and the water guide platform 152 are located outside the water-proof groove.

[0050] The protruding part of the 162 water guide platform, which extends beyond the water-blocking groove, can be fitted with drip lines to ensure smoother water flow.

[0051] Furthermore, in order to make the repair more thorough, step S4 is also included: a second water-proof groove 3 and a third water-proof groove 4 are longitudinally opened on both sides of the hollow part, and the two ends of the second water-proof groove 3 and the third water-proof groove 4 are respectively connected to the two ends of the first water-proof groove 2, so that the first water-proof groove 2, the second water-proof groove 3 and the third water-proof groove 4 surround the seepage area inside.

[0052] To prevent external rainwater from entering the wall structure through small defects on the wall surface and thus affecting the repair effect, step S5 may also be included: applying waterproof material to the seepage area. The waterproof material is set as an exposed transparent waterproof coating (acrylic, silicone, or other materials can be selected according to the actual situation of the wall).

[0053] In order to ensure that the water-blocking strip body 1 can play a water-blocking role, the height of the inclined surface 12 of the water-blocking strip body 1 located at the opening of the first water-blocking groove 2 is lower than the height of the inclined surface 12 located inside the first water-blocking groove 2.

[0054] As is well known, for a building wall to leak, the following conditions must be met: first, there must be water within the wall's structural layer; second, there must be defects in the wall structure (seepage channels); and third, there must be a certain amount of pressure. Therefore, to solve the leakage problem, this application establishes a repair area within the seepage zone. The repair area is larger than the seepage zone, and waterproof strips are installed on the upper edge and both sides of the repair area. These waterproof strips block the seepage channels, but the original water content within the wall's structural layer remains almost unchanged (similar to a container; once full, no more water can enter. Aside from normal gravity and wind pressure, rainwater generally doesn't have much pressure). Therefore, no new diffusion occurs; only less water enters the wall's structural layer. Simultaneously, the waterproof strips in this application have a water-guiding function, diverting some water out of the wall to reduce water accumulation inside. Therefore, this solution effectively prevents water from entering the seepage zone, effectively solving the problem of hollow areas caused by leaks in building exterior walls and achieving the purpose of repairing building leaks. At the same time, the waterproof coating prevents external rainwater from entering the wall's structural layers through small defects in the wall surface, thus preventing it from affecting the repair effect.

[0055] Example 2

[0056] This embodiment focuses on the seepage area located on the inner wall. The difference from Embodiment 1 is that the repair area is set on the outdoor wall surface corresponding to the seepage area 7. Other repair methods are the same as in Embodiment 1.

[0057] Example 3

[0058] The repair of water-seeping areas 7 in horizontal building components such as parapet walls differs from Example 1 in that it can also be achieved by determining the bottom gap 9 of the horizontal building component above the water-seeping area 7, as shown in the attached figure. Figure 7 As shown, the upper edge of the repair area is then placed between the bottom gap 9 and the seepage area, effectively blocking the seepage water from flowing into the seepage area from the bottom gap, thereby further improving the repair effect.

[0059] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the article or apparatus that includes that element.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. The present invention has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
