Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a water-repellent liner for exterior walls and an exterior wall waterproofing structure. Background Technology

[0002] In the current construction industry, exterior wall waterproofing plays a crucial role in ensuring the stability of building structures and improving the quality of indoor living environments. Exterior wall flashing boards, as a key component of exterior wall waterproofing structures, directly affect the waterproofing effect due to their performance.

[0003] Traditional exterior wall drip edges have revealed numerous problems in practical applications. In terms of installation, most drip edges are monolithic structures, making them difficult to adapt flexibly to installation locations of different sizes and shapes. Construction workers often need to cut and bend the drip edges on-site, which is not only time-consuming and labor-intensive but also makes it difficult to guarantee processing accuracy, easily leading to gaps after installation and reduced waterproofing performance. Furthermore, when a part of the drip edge is damaged, due to its monolithic structure, the entire drip edge usually needs to be replaced, resulting in high repair costs and a cumbersome process.

[0004] Current technologies often use sealants such as silicone adhesives to bond the drip edge to the perimeter of the exterior wall and fix the drip edge by drilling holes. The drawbacks are that the sealant is significantly affected by ultraviolet radiation, rainwater erosion, and temperature changes. After long-term use, the adhesive layer is prone to aging and cracking, leading to gaps between the drip edge and the exterior wall. Furthermore, drilling holes damages the structural integrity of the wall, creating potential seepage points. If waterproofing is not properly applied, rainwater can easily seep into the wall through the holes.

[0005] Therefore, it is necessary to use drip edge boards and waterproof structures for the exterior walls. Utility Model Content

[0006] The main purpose of this utility model is to provide a flashing board for exterior walls and an exterior wall waterproofing structure, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An exterior wall flashing includes a bent plate, a groove is provided on the vertical rear portion of the bent plate, a plurality of water guiding grooves are provided on the upper horizontal portion of the bent plate, splicing components are fixedly connected to both ends of the bent plate, and a sound insulation component is fixedly connected to the lower end of the horizontal portion of the bent plate.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figures 1 to 5 As shown, an exterior wall lining includes a bent plate 1. A groove 2 is provided on the vertical part of the rear side of the bent plate 1. Several water guide grooves 6 are provided on the upper horizontal part of the bent plate 1. Splicing components 4 are fixedly connected to both ends of the bent plate 1. A sound insulation component 5 is fixedly connected to the lower end of the horizontal part of the bent plate 1.

[0026] In the specific implementation process of this utility model, firstly, the staff measures the length of the lower outer wall of the window to be installed, and then takes out several bending plates 1 according to the length. Then, under the action of the internal structure of the splicing component 4, the several bending plates 1 are spliced ​​together. Then, the entire spliced ​​device is placed on the lower edge of the window outer wall. At the same time, the internal component structure of the sound insulation component 5 can ensure that the horizontal part of the bending plate 1 is always tilted forward. When the entire device is placed in a suitable position, the slide 2 is connected to the water guide hole on the lower outer side of the window. Then, the staff installs the locking mechanism 3 into the slide 2, so that the locking mechanism 3 slides in the inner cavity of the slide 2 to the position connected to the water guide hole. Then, by rotating the internal structure of the locking mechanism 3, the "insertion-rotation adjustment" quick installation mode fixes the entire device in the water guide hole of the window, avoiding the problem of difficult separation after the adhesive ages or leaving marks on the wall due to drilling fixation.

[0027] Then, while it is raining outside, the rainwater hits the horizontal part of the bent plate 1. The sound insulation component 5 effectively reduces the sound of the rainwater hitting the surface of the bent plate 1. The water guide channel 6 allows the rainwater to fall in an oblique line when it comes into contact with the horizontal part of the bent plate 1, preventing the rainwater from accumulating or splashing at the edge of the bent plate 1, improving drainage efficiency, ensuring that the rainwater is quickly drained away from the wall, reducing the erosion of the wall and window sill by rainwater, and extending the service life of the building.

[0028] Example 2: In order to achieve the purpose of installing the bent plate 1 at an angle, refer to... Figure 2In this solution, the sound insulation component 5 includes a sound insulation board 51, which is fixedly connected to the lower end of the horizontal part of the bent plate 1. Support plates 52 are fixedly connected to the front and rear sides of the lower end of the sound insulation board 51.

[0029] Furthermore, the length of the rear support plate 52 is longer than that of the front support plate 52.

[0030] In the above, by directly placing the bent plate 1 at the lower edge of the outer wall of the window, the two support plates 52 are in contact with the lower edge of the outer wall. Then, by setting the support plates 52 at different heights, the horizontal part of the bent plate 1 is tilted forward during installation, so that the water can flow forward and be discharged. Then, under the action of the sound insulation plate 51, the rainwater can effectively absorb the rainwater hitting sound when it falls on the horizontal part of the bent plate 1.

[0031] The sound insulation board 51 mentioned above can be made of various types such as mineral wool sound insulation board, metal sound insulation board, glass fiber sound insulation board, calcium silicate board, rock wool board, foam plastic board, glass board, etc., with an average sound insulation of 30-37dB, which can effectively reduce the sound of rainwater falling on the horizontal part of the bent board 1.

[0032] Specifically, in order to achieve the goal of splicing, refer to Figure 3 In this solution, the splicing component 4 includes a T-shaped block 41 and a T-shaped groove 42. The T-shaped block 41 is fixedly connected to the left end of the horizontal part of the bending plate 1, and the T-shaped groove 42 is opened at the right end of the horizontal part of the bending plate 1.

[0033] In the above, the purpose of splicing is achieved by directly sliding the T-shaped block 41 on the right end of one bending plate 1 into the inner cavity of the T-shaped groove 42 on the front left end of another bending plate 1. After splicing the T-shaped block 41 and the T-shaped groove 42, even if rainwater falls into the splicing gap, it will slide out from the front as the bending plate 1 tilts, preventing rainwater from accumulating in the splicing gap.

[0034] Specifically, in order to lock the bending plate 1 into the window's drainage hole, refer to... Figure 4 In this solution, the locking mechanism 3 includes a fixed cylinder 31, which is movably connected to the inner cavity of the slide groove 2. A stop plate 33 is fixedly connected to the rear end of the fixed cylinder 31. A threaded hole 32 is opened in the middle of the front end of the fixed cylinder 31. A screw post 36 is threadedly connected to the inner cavity of the threaded hole 32. A turntable 37 is fixedly connected to the front end of the screw post 36. A cylinder 34 is fixedly connected to the rear end of the turntable 37 away from its axis. A pressure plate 35 is fixedly connected to the rear end of the cylinder 34.

[0035] Furthermore, the diameter of the hole in the middle of the cylinder 34 and the pressure plate 35 is larger than the diameter of the hole in the fixed cylinder 31.

[0036] In the above process, the operator directly inserts the fixing cylinder 31 and the abutment plate 33 horizontally into the inner cavity of the slide groove 2, and then the abutment plate 33 enters the water guide hole of the window. Then, the fixing cylinder 31 is rotated so that the abutment plate 33 is in a vertical state, and the two ends of the abutment plate 33 hook onto the inner wall of the water guide hole. Then, the rotating turntable 37 drives the screw post 36 to rotate, so that the screw post 36 is screwed into the inner cavity of the threaded hole 32. At the same time, the cylinder 34 rotates and moves backward on the surface of the fixing cylinder 31, so that the pressure plate 35 contacts the surface of the vertical part of the bending plate 1. Then, by gradually tightening the screw post 36, the pressure plate 35 and the abutment plate 33 move closer to each other and clamp the vertical part of the bending plate 1, thereby achieving the purpose of fixing the bending plate 1.

[0037] This utility model also discloses an exterior wall waterproofing structure having the above-mentioned exterior wall drip edge.

[0038] It should be noted that the specific installation method of the sound insulation board 51 used in this utility model is a conventional design, and will not be described in detail here.

[0039] The working principle of this utility model is as follows: First, the staff measures the length of the lower outer wall of the window to be installed. Then, according to the length, several bent plates 1 are taken out. Then, under the action of the internal structure of the splicing component 4, several bent plates 1 are spliced ​​together. Then, the entire spliced ​​device is placed on the lower edge of the window outer wall. At the same time, the internal component structure of the sound insulation component 5 ensures that the horizontal part of the bent plate 1 is always tilted forward. When the entire device is placed in the appropriate position, the slide 2 is connected to the water guide hole on the lower outer side of the window. Then, the staff installs the locking mechanism 3 into the slide 2, so that the locking mechanism 3 slides in the inner cavity of the slide 2 to the position connected to the water guide hole. Then, by rotating the internal structure of the locking mechanism 3, the "insertion-rotation adjustment" quick installation mode fixes the entire device in the water guide hole of the window, avoiding the problem of difficult separation after the adhesive ages or leaving marks on the wall due to drilling fixation.

[0040] Then, while it is raining outside, the rainwater hits the horizontal part of the bent plate 1. The sound insulation component 5 effectively reduces the sound of the rainwater hitting the surface of the bent plate 1. The water guide channel 6 allows the rainwater to fall in an oblique line when it comes into contact with the horizontal part of the bent plate 1, preventing the rainwater from accumulating or splashing at the edge of the bent plate 1, improving drainage efficiency, ensuring that the rainwater is quickly drained away from the wall, reducing the erosion of the wall and window sill by rainwater, and extending the service life of the building.
