DETAILED DESCRIPTION
[0022] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0023] Example 1: Figures 1 to 5The illustrated waterproof structure of an outer window node includes a wall 1 and an outer window main frame 2. The wall 1 has a window with the same shape as the outer window main frame 2 for installing the outer window main frame 2. The outer window main frame 2 is embedded in the wall 1, and the outer window main frame 2 is aligned with the outer side of the wall 1.

A second sealing material 4 is provided on the upper surface and the lower surface of the upper decorative frame 9.1. The second sealing material 4 can be made of sealant, and the sealant is used to cover the joint between the upper surface of the upper decorative frame 9.1 and the wall 1 structure, and the joint between the lower surface of the upper decorative frame 9.1 and the outer window main frame 2. Figure 3 Similarly, the upper and lower surfaces of the lower decorative frame 9.2 are also provided with a second sealing material 4, which can be a sealant, and the sealant is used to cover the joint between the upper surface of the lower decorative frame 9.2 and the outer window main frame 2, and to cover the joint between the lower surface of the lower decorative frame 9.2 and the wall 1 structure, as shown in detail. Figure 4 shown.
[0025] In such Figure 2 As shown, a first sealing material 3 is also provided on the direct connection surface between the wall 1 and the outer window main frame 2. The first sealing material 3 can be made of polyurethane foam. The outer edge installation seam of the wall 1 and the outer window main frame 2 is filled with polyurethane foam, which not only has a sealing effect, but also has the effect of stabilizing the frame of the outer window main frame 2.
[0026] It should be said that the wall 1 structure is composed of multiple layers of materials. The wall 1 structure from indoors to outdoors is: paint, 12mm fire-resistant gypsum board, 9.5mm structural oriented strand board, insulation cotton + 38*140 keel column 17, 9.5mm structural oriented strand board, breathing paper, water-repellent strip 11, 10mm cement fiber board, and paint.
[0027] like Figure 1 or Figure 5As shown, two grooves 5 are arranged on the outer frame edge of the outer window main frame 2, and the grooves 5 are distributed in an annular manner around the outer window main frame 2 and directly assembled with the wall 1 structure, and a first sealing material 3 (polyurethane foam glue) is arranged in the groove 5; the polyurethane foam glue can bond the outer window main frame 2 with the wall 1 structure, and play a stabilizing and sealing effect. Since the wall 1 structure is composed of a multi-layer structure, in order to prevent the poor sealing effect between the layered structure and the outer window main frame 2, a keel column frame 18 is sleeved on the thermal insulation cotton + keel column 17 structure of the wall, so that the first sealing material 3 is directly in contact with the keel column frame 18 and the groove 5, thereby improving the sealing effect and preventing leakage.
[0028] A window sill structure is also provided on the inner side of the wall 1, and the window sill structure includes an upper window sill 6 and a lower window sill 7, wherein the upper window sill 6 and the lower window sill 7 both include a horizontal platform 6.1 and a vertical platform 6.2, the horizontal platform 6.1 directly abuts against the inner side of the outer window main frame 2 and the layered surface of the wall 1 structure to form a closing, and the vertical platform 6.2 directly fits against the inner side surface of the wall 1 to form a closing, and the horizontal platform 6.1 and the vertical platform 6.2 form a right-angle structure, and a third sealing material 8 is provided at the closing point between the horizontal platform 6.1 of the window sill and the outer window main frame 2 and at the closing point between the vertical platform 6.2 of the window sill and the inner side of the wall 1, and the third sealing material 8 can specifically be a sealant.
[0029] By providing a three-layer sealant structure (a first sealing material 3, a second sealing material 4 and a third sealing material 8), a waterproof and anti-leakage effect is achieved between the outer window node and the house wall 1.
[0030] In the outer structure of the wall 1, the position of the water strip 11 is flush with the outer surface of the decorative frame 9 and the outer window main frame 2, and a first gap 10 is left between the water strip 11 and the wall 1 structure other than the water strip 11 and the upper surface of the upper decorative frame 9.1. Figure 1 or Figure 3 and a second gap 19 is left between the lower surface of the lower decorative frame 9.2, as shown Figure 1 or Figure 4 shown.
[0031] At the upper decorative frame 9.1, a flashing plate 12 is also arranged in the position of the water strip 11. The flashing plate 12 includes two sections, one is a vertical section 12.1, and the other is an inclined section 12.2. The vertical section 12.1 of the flashing plate 12 is clamped between the water strip 11 and the keel column frame 18 to prevent the water discharged from the water strip 11 from leaking to the keel column structure on the inner side of the wall 1; and the inclined section 12.2 is arranged in the first gap 10. The vertical section 12.1 of the flashing plate 12. 1 and the inclined section 12.2 are an integral structure, the inclined direction of the inclined section 12.2 is from the inner side of the wall 1 to the outer side of the wall 1 and is inclined downward, the inclination angle is generally set at about 15°, and the end of the inclined section 12.2 extends all the way to the outer side of the facade of the wall 1, and the water discharged from the downspout 11 and the rainwater flowing down the outer surface of the wall 1 are directly guided away through the inclined section 12.2, reducing the accumulation of rainwater between the upper surfaces of the upper decorative frame 9.1, thereby reducing the occurrence of leakage.

Since the lower surface of the lower decorative frame 9.2 is horizontally arranged, when accumulated water or rainwater slides from the upper surface of the lower decorative frame 9.2 to the lower surface, the rainwater will fall on the lower surface of the lower decorative frame 9.2. However, some accumulated water may flow along the lower surface of the lower decorative frame 9.2 to the inner side of the wall 1 and then enter the internal structure of the wall 1. Therefore, the drip groove 13 is mainly used to prevent rainwater from flowing along the lower surface of the lower decorative frame 9.2 and block it to prevent it from flowing into the wall 1. The drip groove 13 is arranged on the outer surface of the wall 1 and outside. The drip groove 13 cannot be arranged on the outer surface close to the inner side of the outer surface of the wall 1 to prevent accumulated water from dripping from the drip groove 13 into the second gap 19 and then entering the wall 1.
[0033] Example 2: Figures 1 to 5 The illustrated waterproof structure of an outer window node includes a wall 1 and an outer window main frame 2.

A second sealing material 4 is provided on the upper surface and the lower surface of the upper decorative frame 9.1. The second sealing material 4 can be made of sealant, and the sealant is used to cover the joint between the upper surface of the upper decorative frame 9.1 and the wall 1 structure, and the joint between the lower surface of the upper decorative frame 9.1 and the outer window main frame 2. Figure 3 Similarly, the upper and lower surfaces of the lower decorative frame 9.2 are also provided with a second sealing material 4, which can be a sealant, and the sealant is used to cover the joint between the upper surface of the lower decorative frame 9.2 and the outer window main frame 2, and to cover the joint between the lower surface of the lower decorative frame 9.2 and the wall 1 structure, as shown in detail. Figure 4 shown.
[0035] In such Figure 2 As shown, a first sealing material 3 is also provided on the direct connection surface between the wall 1 and the outer window main frame 2. The first sealing material 3 can be made of polyurethane foam. The outer edge installation seam of the wall 1 and the outer window main frame 2 is filled with polyurethane foam, which not only has a sealing effect, but also has the effect of stabilizing the frame of the outer window main frame 2.
[0036] It should be said that the wall 1 structure is composed of multiple layers of materials. The wall 1 structure from indoors to outdoors is: paint, 12mm fire-resistant gypsum board, 9.5mm structural oriented strand board, insulation cotton + 38*140 keel column 17, 9.5mm structural oriented strand board, breathing paper, water-repellent strip 11, 10mm cement fiber board, and paint.
[0037] like Figure 1 or Figure 5 As shown, two grooves 5 are arranged on the outer frame edge of the outer window main frame 2, and the grooves 5 are distributed in an annular manner around the outer window main frame 2 and directly assembled with the wall 1 structure, and a first sealing material 3 (polyurethane foam glue) is arranged in the groove 5; the polyurethane foam glue can bond the outer window main frame 2 with the wall 1 structure, and play a stabilizing and sealing effect. Since the wall 1 structure is composed of a multi-layer structure, in order to prevent the poor sealing effect between the layered structure and the outer window main frame 2, a keel column frame 18 is sleeved on the thermal insulation cotton + keel column 17 structure of the wall, so that the first sealing material 3 is directly in contact with the keel column frame 18 and the groove 5, thereby improving the sealing effect and preventing leakage.
[0038] A window sill structure is also provided on the inner side of the wall 1, and the window sill structure includes an upper window sill 6 and a lower window sill 7, wherein the upper window sill 6 and the lower window sill 7 both include a horizontal platform 6.1 and a vertical platform 6.2, the horizontal platform 6.1 directly abuts against the inner side of the outer window main frame 2 and the layered surface of the wall 1 structure to form a closing, and the vertical platform 6.2 directly fits against the inner side surface of the wall 1 to form a closing, and the horizontal platform 6.1 and the vertical platform 6.2 form a right-angle structure, and a third sealing material 8 is provided at the closing point between the horizontal platform 6.1 of the window sill and the outer window main frame 2 and at the closing point between the vertical platform 6.2 of the window sill and the inner side of the wall 1, and the third sealing material 8 can specifically be a sealant.
[0039] By providing a three-layer sealant structure (a first sealing material 3, a second sealing material 4 and a third sealing material 8), a waterproof and anti-leakage effect is achieved between the outer window node and the house wall 1.
[0040] In the outer structure of the wall 1, the position of the water strip 11 is flush with the outer surface of the decorative frame 9 and the outer window main frame 2, and a first gap 10 is left between the water strip 11 and the wall 1 structure other than the water strip 11 and the upper surface of the upper decorative frame 9.1. Figure 1 or Figure 3 and a second gap 19 is left between the lower surface of the lower decorative frame 9.2, as shown Figure 1 or Figure 4 shown.
[0041] At the upper decorative frame 9.1, a flashing plate 12 is also arranged in the position of the water strip 11. The flashing plate 12 includes two sections, one is a vertical section 12.1, and the other is an inclined section 12.2. The vertical section 12.1 of the flashing plate 12 is clamped between the water strip 11 and the keel column frame 18 to prevent the water discharged from the water strip 11 from leaking to the keel column structure on the inner side of the wall 1; and the inclined section 12.2 is arranged in the first gap 10. The vertical section 12.1 of the flashing plate 12. 1 and the inclined section 12.2 are an integral structure, the inclined direction of the inclined section 12.2 is from the inner side of the wall 1 to the outer side of the wall 1 and is inclined downward, the inclination angle is generally set at about 15°, and the end of the inclined section 12.2 extends all the way to the outer side of the facade of the wall 1, and the water discharged from the downspout 11 and the rainwater flowing down the outer surface of the wall 1 are directly guided away through the inclined section 12.2, reducing the accumulation of rainwater between the upper surfaces of the upper decorative frame 9.1, thereby reducing the occurrence of leakage.
[0042] At the lower decorative frame 9.2, the upper surface of the lower decorative frame 9.2 is inclined, and the lower surface of the lower decorative frame 9.2 is horizontally arranged, which increases the connection area between the lower decorative frame 9.2 and the outer window main frame 2 and the wall 1 structure, and improves the connection strength; in addition, the inclination direction of the upper surface of the lower decorative frame 9.2 is also arranged downward from indoors to outdoors, which can directly and timely guide the rainwater flowing down the window to prevent the rainwater from accumulating on the upper surface of the lower decorative frame 9.2, and the lower surface of the lower decorative frame 9.2 is also provided with A drip groove 13 is provided. Since the lower surface of the lower decorative frame 9.2 is horizontally arranged, when accumulated water or rainwater slides from the upper surface of the lower decorative frame 9.2 to the lower surface, the rainwater will fall on the lower surface of the lower decorative frame 9.2. However, some accumulated water may flow along the lower surface of the lower decorative frame 9.2 to the inner side of the wall 1 and then enter the internal structure of the wall 1. Therefore, the drip groove 13 is mainly used to prevent rainwater from flowing along the lower surface of the lower decorative frame 9.2 and block it to prevent it from flowing into the wall 1.
