[0024] The technical solution of the present invention will be further described below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0025] Example 1: Figures 1 to 3 as well as Figures 5 to 7 A parapet hidden flashing installation node is shown, including a wall 1, which is a wooden parapet. A waistline layer 6 is provided on the outside of the wall 1, and the waistline layer 6 is a decorative layer on the outside of the wall 1. A first flashing board 2 is provided on the top of the wall 1, and a second flashing board 8 is provided between the waistline layer 6 and the wall 1. In this solution, by cleverly using the flashing board, the waterproof, insect-proof and anti-seepage requirements are met, and the overall aesthetics of the top of the wall 1 and the outside of the wall 1 are improved.

[0026] Specifically, the first flashing plate 2 is a bent piece, and is bent as follows Figure 2 and Figure 3 As shown, the top of the first flashing board 2 has a certain slope, and the first flashing board 2 is erected as a whole at the top position of the wall 1, with the top of the wall 1 as the main supporting part of the first flashing board 2. The two sides of the first flashing board 2 extend to the inside and outside of the wall 1, and are bent beyond the edges on both sides of the wall 1 to form a drip edge 4. The drip edge 4 extends downward and is lower than the top position of the outer wall finish 17, and then bends toward the wall 1 again to form a gap 5 between it and the wall 1, and finally bends into a vertical shape and is embedded in the position of the water strip 3 inside the wall 1.

[0027] In this solution, the first flashing plate 2 is formed by bending a single piece of 1mm thick stainless steel. After bending, the interior is hollow, significantly reducing the weight of the first flashing plate 2. Finally, the first flashing plate 2 is initially secured to the wall 1 by bending its two ends (embedding portions 14). Of course, to enhance the securing effect of the first flashing plate 2, screws can be used at the embedding portions 14 of the first flashing plate 2 to ensure a firm fit between the first flashing plate 2 and the wall 1. Furthermore, since the embedding portions 14 of the first flashing plate 2 are located inwardly of the drip edge 4, screws and other components can be concealed, significantly enhancing the aesthetics of the first flashing plate 2 and the top of the wall 1.

[0028] It should be noted that in this scheme, the structure of wall 1 is: from the outside to the inside, there are 17 layers of wall exterior finishing, 12mm cement board, 25×38 anticorrosive wood water strip 3, 0.1mm breathing paper, 10mm OSB, 38×140SPF keel 18 (the top is a stainless steel first flashing board 2), 10mm OSB, 0.1mm breathing paper, 25×38 anticorrosive wood water strip 3, 12mm cement board, and wall interior surface layer.

[0029] Water-adapting strips 3 are used on both the inside and outside of the wall 1 to ensure that the water vapor on the breathing paper flows downward along the water-adapting strips 3, making the wall 1 breathable. Insect-proof nets 16 are provided on the top of the water-adapting strips 3 on both sides of the wall 1. The insect-proof nets 16 are respectively in contact with the cement boards and the breathing paper on both sides, and the first flashing board 2 is embedded between the insect-proof nets 16 and the breathing paper. The top of the first flashing board 2 is fixed by the top limit of the wall 1, and the embedded part 14 at the bottom of the first flashing board 2 is fixed by screws and the internal layer structure of the wall 1, so that the first flashing board 2 can be completely fixed.

[0030] It should be noted that the slope of the top of the first flashing plate 2 is generally set between 2% and 3%. In this embodiment, the slope of the first flashing plate 2 toward the sides of the wall 1 is 2%, which is a percentage representation of slope, the most commonly used method of expressing slope. That is, the slope on both sides of the top of the first flashing plate 2 is approximately 1.12°. The bend angle at the bottom of the drip edge 4 is close to 45°, which creates an effective ventilation space inside the drip edge 4, improving the air permeability of the wall 1.

[0031] The outside of the wall 1 is also provided with a waistline layer 6 as a decorative layer, and an embedding groove 7 is provided between the waistline layer 6 and the wall 1. The embedding groove 7 is generally provided at the upper position of the waistline layer 6, and a second flashing board 8 is installed in the embedding groove 7.

[0032] Specifically, such as Figures 5 to 7As shown, the second flashing plate 8 is a double-layered metal structure made of aluminum sheet with a thickness of 0.8 mm. The second flashing plate 8 includes an open end 10 and a closed end 9. The upper and lower aluminum sheets of the open end 10 of the second flashing plate 8 are bent obliquely outward toward the closed end 10 to form an insert 11. One side of the open end 10 of the second flashing plate 8 is embedded in the inlay groove 7, forming a snap-fit ​​fit between the insert 11 and the inlay groove 7. Because the second flashing plate 8 is made of aluminum sheet, it has a certain degree of elasticity. When pressure is applied to the upper and lower aluminum sheets of the second flashing plate 8, the open end 10 of the second flashing plate 8 closes and becomes thinner, reducing the overall thickness of the second flashing plate 8. When the pressure is released, the open end 10 reopens, restoring its original thickness. Therefore, the open end 10 of the second flashing plate 8 can be embedded in the inlay groove 7. Specifically, when installing the second flashing plate 8, the second flashing plate 8 is pressed up and down, causing the open end 10 to close and thin out to fit the size of the slot 7. After the open end 10 of the second flashing plate 8 is inserted into the slot 7, the pressure on the second flashing plate 8 is released. The open end 10 of the second flashing plate 8 is then reopened, and the inserts 11 on either side of the open end 10 snap into the slot 7 to secure it. Finally, the slot 7 can be filled with weatherproof glue or other materials to completely secure the second flashing plate 8 within the slot 7. After the second flashing plate 8 is installed, there is no gap between the exterior wall finish 17 and the upper surface of the second flashing plate 8, ensuring aesthetics. The slot 7 utilizes a dovetail groove with a larger inner portion and a smaller outer portion, which effectively engages the inserts 11 and secures the second flashing plate 8.

[0033] The closed end 9 of the second flashing plate 8 is a bent portion 12, which is made of two layers of aluminum plates joined together and bent. The bending direction is downward, and the bent portion 12 is located outside the waistline layer 6. The closed end 9 can achieve the external sealing of the second flashing plate 8 on the one hand, and can also play a drainage and diversion effect on the other hand. The bottom of the second flashing plate 8 is arranged horizontally, so that the bottom of the second flashing plate 8 is in contact with the waistline layer 6. Since the second flashing plate 8 is composed of two layers of aluminum plates and arranged at an angle, the bottom aluminum plate is arranged horizontally, and the top aluminum plate will be in an inclined state, which can achieve a good drainage and anti-seepage effect. The second flashing plate 8 is suitable for situations where the wall exterior finish 17 has been completed and the wall layer 1 cannot be disassembled for pre-embedding. The use of a double-layer metal second flashing plate 8 utilizes the metal elasticity to complete the installation limit, which is convenient to operate.

[0034] Example 2: Figures 1 to 2 as well as Figures 4 to 7A parapet hidden flashing installation node is shown, including a wall 1, which is a wooden parapet. A waistline layer 6 is provided on the outside of the wall 1, and the waistline layer 6 is a decorative layer on the outside of the wall 1. A first flashing board 2 is provided on the top of the wall 1, and a second flashing board 8 is provided between the waistline layer 6 and the wall 1. In this solution, by cleverly using the flashing board, the waterproof, insect-proof and anti-seepage requirements are met, and the overall aesthetics of the top of the wall 1 and the outside of the wall 1 are improved.

[0035] Specifically, the first flashing plate 2 is a bent piece, and is bent as follows Figure 2 and Figure 4 As shown, the first flashing board 2 includes a sealing top 13 and an embedded part 14. The sealing top 13 has a certain slope, and the sealing top 13 is built as a whole at the top position of the wall 1, with the top of the wall 1 as the main supporting part of the first flashing board 2. The two sides of the sealing top 13 extend to the inside and outside of the wall 1, and are bent beyond the edges on both sides of the wall 1 to form a drip edge 4. The drip edge 4 extends downward and is lower than the top position of the outer wall finishing 17, and then bends toward the wall 1 again to form a gap 5 between the wall 1, and the embedded part 14 is an inverted L-shape. The long side of the embedded part 14 is arranged vertically and embedded in the layer structure of the wall 1, and the short side of the embedded part 14 is arranged horizontally and has a section of inclined sheet layer at the end that fits with the end of the drip edge 4. The sheet layer and the bottom of the drip edge 4 are clamped and limited at the upper and lower positions toward the wall 1 to achieve the fixing effect of the sealing top 13.

[0036] In this solution, the first flashing plate 2 is composed of a top cover 13 and two mounting portions 14 located on either side of the top cover 13. Both the top cover 13 and the mounting portions 14 are 1mm thick stainless steel plates. The mounting portions 14 and the top cover 13 form a hollow interior, significantly reducing the weight of the first flashing plate 2. Finally, the two ends of the first flashing plate 2 (the mounting portions 14) are embedded within the wall 1, completing the initial fixation of the first flashing plate 2. Of course, to enhance the fixing effect of the first flashing plate 2, fasteners 15 can be used at the mounting portions 14 of the first flashing plate 2 to secure the first flashing plate 2 to the wall 1. These fasteners 15 can be screws. Furthermore, since the mounting portions 14 of the first flashing plate 2 are located inside the drip edge 4, screws and other components can be concealed, significantly improving the aesthetics of the first flashing plate 2 and the top of the wall 1.

[0037] It should be noted that in this scheme, the structure of wall 1 is: from the outside to the inside, there are 17 layers of wall exterior finishing, 12mm cement board, 25×38 anticorrosive wood water strip 3, 0.1mm breathing paper, 10mm OSB, 38×140SPF keel 18 (the top is a stainless steel first flashing board 2), 10mm OSB, 0.1mm breathing paper, 25×38 anticorrosive wood water strip 3, 12mm cement board, and wall interior surface layer.

[0038] Water-adapting strips 3 are used on both the inside and outside of the wall 1 to ensure that the water vapor on the breathing paper flows downward along the water-adapting strips 3, making the wall 1 breathable. Insect-proof nets 16 are provided on the top of the water-adapting strips 3 on both sides of the wall 1. The insect-proof nets 16 are respectively in contact with the cement boards and the breathing paper on both sides, and the first flashing board 2 is embedded between the insect-proof nets 16 and the breathing paper. The top of the first flashing board 2 is fixed by the top limit of the wall 1, and the embedded part 14 at the bottom of the first flashing board 2 is fixed by screws and the internal layer structure of the wall 1, so that the first flashing board 2 can be completely fixed.

[0039] It should be noted that the slope of the top of the first flashing plate 2 is generally set between 2% and 3%. In this embodiment, the slope of the first flashing plate 2 toward the sides of the wall 1 is 2%, which is a percentage representation of slope, the most commonly used method of expressing slope. That is, the slope on both sides of the top of the first flashing plate 2 is approximately 1.12°. The bend angle at the bottom of the drip edge 4 is close to 45°, which creates an effective ventilation space inside the drip edge 4, improving the air permeability of the wall 1.

[0040] The outside of the wall 1 is also provided with a waistline layer 6 as a decorative layer, and an embedding groove 7 is provided between the waistline layer 6 and the wall 1. The embedding groove 7 is generally provided at the upper position of the waistline layer 6, and a second flashing board 8 is installed in the embedding groove 7.

[0041] Specifically, such as Figures 5 to 7As shown, the second flashing plate 8 is a double-layered metal structure made of aluminum sheet with a thickness of 0.8 mm. The second flashing plate 8 includes an open end 10 and a closed end 9. The upper and lower aluminum sheets of the open end 10 of the second flashing plate 8 are bent obliquely outward toward the closed end 10 to form an insert 11. One side of the open end 10 of the second flashing plate 8 is embedded in the inlay groove 7, forming a snap-fit ​​fit between the insert 11 and the inlay groove 7. Because the second flashing plate 8 is made of aluminum sheet, it has a certain degree of elasticity. When pressure is applied to the upper and lower aluminum sheets of the second flashing plate 8, the open end 10 of the second flashing plate 8 closes and becomes thinner, reducing the overall thickness of the second flashing plate 8. When the pressure is released, the open end 10 reopens, restoring its original thickness. Therefore, the open end 10 of the second flashing plate 8 can be embedded in the inlay groove 7. Specifically, when installing the second flashing plate 8, the second flashing plate 8 is pressed up and down, causing the open end 10 to close and thin out to fit the size of the slot 7. After the open end 10 of the second flashing plate 8 is inserted into the slot 7, the pressure on the second flashing plate 8 is released. The open end 10 of the second flashing plate 8 is then reopened, and the inserts 11 on either side of the open end 10 snap into the slot 7 to secure it. Finally, the slot 7 can be filled with weatherproof glue or other materials to completely secure the second flashing plate 8 within the slot 7. After the second flashing plate 8 is installed, there is no gap between the exterior wall finish 17 and the upper surface of the second flashing plate 8, ensuring aesthetics. The slot 7 utilizes a dovetail groove with a larger inner portion and a smaller outer portion, which effectively engages the inserts 11 and secures the second flashing plate 8.

[0042] The closed end 9 of the second flashing plate 8 is a bent portion 12, which is made of two layers of aluminum plates joined together and bent. The bending direction is downward, and the bent portion 12 is located outside the waistline layer 6. The closed end 9 can achieve the external sealing of the second flashing plate 8 on the one hand, and can also play a drainage and diversion effect on the other hand. The bottom of the second flashing plate 8 is arranged horizontally, so that the bottom of the second flashing plate 8 is in contact with the waistline layer 6. Since the second flashing plate 8 is composed of two layers of aluminum plates and arranged at an angle, the bottom aluminum plate is arranged horizontally, and the top aluminum plate will be in an inclined state, which can achieve a good drainage and anti-seepage effect. The second flashing plate 8 is suitable for situations where the wall exterior finish 17 has been completed and the wall layer 1 cannot be disassembled for pre-embedding. The use of a double-layer metal second flashing plate 8 utilizes the metal elasticity to complete the installation limit, which is convenient to operate.
