[0002] Settlement joints in exterior walls are a key structural feature in buildings to address settlement deformation, but they can also become a potential source of rainwater leakage.

[0003] Settlement joints in the exterior walls of frame structures are mainly concentrated at the junction of the secondary structure (masonry structure) and the primary structure (beam-column concrete structure). Because the two are made of different building materials, they have different coefficients of thermal expansion under different thermal expansion and contraction conditions, which can easily lead to cracking and widening of gaps at the junction, directly causing water seepage in this area.

[0017] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] See Figures 1 to 2 To further elaborate on this application: The exterior wall settlement joint waterproofing structure 20 includes a shielding layer 30, which is disposed on the surface of the exterior wall 10 to shield the settlement joint 00 on the exterior wall 10; the shielding layer is pasted on the exterior wall surface; wherein, the shielding layer is EPS line, which has a certain elasticity and can adapt to slight settlement deformation to avoid direct cracking.

[0019] A crack-resistant layer 40 is provided between the top of the shielding layer 30 and the outer wall 10. The crack-resistant layer 40 can enhance the connection strength between the shielding layer 30 and the wall, prevent the shielding layer 30 from cracking due to temperature changes and structural settlement, and at the same time lay the foundation for subsequent waterproofing processes.

[0020] A waterproof layer 50 is located outside the shielding layer 30, covering the shielding layer 30 and the crack-resistant layer 40, and is used to block rainwater.

[0021] The waterproof layer 50 includes a first waterproof structure 510 and a second waterproof structure 520. The first waterproof structure 510 covers the shielding layer 30 and the crack-resistant layer 40. The second waterproof structure 520 is connected to the outer wall 10 and covers the first waterproof structure 510.

[0022] A sealing layer is provided between the outer wall 10 and the second waterproof structure 520 for sealing and connecting the outer wall 10 and the second waterproof structure 520.

[0023] This application uses a shielding layer 30 to cover the outside of the settlement joint 00 to accommodate settlement deformation and prevent rigid cracking. The top of the shielding layer 30 and the surface of the outer wall 10 are provided with a crack-resistant layer 40 to enhance the overall structural integrity. It is covered by two layers of waterproof structure, and then a sealing layer seals the space between the outer wall 10 and the waterproof structure to prevent rainwater from seeping in between, thereby improving the overall waterproofness of the structure and preventing moisture from seeping into the settlement joint 00.

[0024] In this embodiment, the first waterproof structure 510 includes a waterproof coating and a mesh fabric, with the mesh fabric disposed within the waterproof coating. The waterproof coating is a waterproof mortar; it can also be a cement-based penetrating crystalline waterproof coating or a high-elasticity JS waterproof coating, etc. The mesh fabric enhances the crack resistance of the waterproof mortar layer, preventing it from drying and cracking, thus ensuring its waterproof effect.

[0025] The second waterproof structure 520 includes a water-blocking plate, which provides physical waterproofing. The upper part 5210 of the water-blocking plate is fixedly connected to the exterior wall 10, and the lower part of the water-blocking plate is attached to the first waterproof structure 510. The upper part 5210 of the water-blocking plate can be fixed to the exterior wall 10 using expansion bolts, or alternatively, steel nails. The lower part 5220 of the water-blocking plate, attached to the first waterproof structure 510, effectively reduces the gap between the water-blocking plate and the shielding layer 30, thereby reducing leakage. In this embodiment, the water-blocking plate is an aluminum composite panel, which is lightweight and weather-resistant.

[0026] The lower part 5220 of the water-blocking plate extends downward from the shielding layer 30. It can form a water-blocking eave, thereby preventing rainwater from directly washing the first waterproof structure 510 on the surface of the shielding layer 30. At the same time, it can spatially isolate rainwater from contact with the bottom of the shielding layer 30.

[0027] In one embodiment, a water-guiding structure 60 is further provided on top of the shielding layer 30, and the water-guiding structure 60 is located between the crack-resistant layer 40 and the first waterproof structure 510. The water-guiding structure 60 covers the crack-resistant layer 40 and is inclined outward from the outer wall 10. The water-guiding structure 60 can promptly drain rainwater, preventing water accumulation in the corner between the shielding layer 30 and the outer wall 10.

[0028] In this embodiment, the water-guiding structure 60 is made of a waterproof material, such as waterproof mortar or waterproof coating. The water-guiding structure 60 can be integrated with the first waterproof structure 510; that is, when arranging the waterproof coating in the first waterproof structure 510, the water-guiding structure 60 is directly formed between the shielding layer 30 and the outer wall 10 using the waterproof coating, and then the mesh fabric is arranged.

[0029] The sealing layer is a sealant. In this embodiment, the sealing layer is a silicone structural sealant; the sealant forms the sealing layer through the gap between the upper part 5210 of the baffle and the outer wall 10, thereby preventing rainwater from seeping in from the top of the baffle.
