Description

Technical Field

[0001] This utility model relates to the field of exterior window installation technology. More specifically, this utility model relates to a waterproof and heat-insulating window installation node structure. Background Technology

[0002] In the construction industry, windows, as a crucial component of the building envelope, have a vital impact on the overall performance of a building due to their waterproofing and thermal insulation properties. However, traditional waterproof and thermally insulated windows currently suffer from numerous problems in practical applications. Inadequate sealing of the gaps between the window frame and the wall allows rainwater to easily seep into the room, causing dampness and mold, affecting not only the building's aesthetics but also its lifespan. Simultaneously, poor sealing between the window frame and the wall allows heat to easily dissipate through the gaps, significantly reducing the room's thermal insulation effect. Furthermore, existing waterproof and thermally insulated windows lack effective drainage measures at the bottom of the window frame, causing rainwater to accumulate. When rainwater accumulates to a certain level, it may seep into the room through the gaps between the window frame and the wall. Moreover, existing drainage structures are simplistic and inefficient, failing to quickly and effectively drain rainwater. In extreme weather conditions such as heavy rain, drainage problems are more likely to occur, further exacerbating the risk of indoor leakage. Existing technologies, such as the utility model patent with authorization announcement number CN217176268U, disclose a construction node for the installation of a heat-insulating window, which improves the overall waterproofness and sealing of the window, but its drainage performance is limited and needs to be improved. Utility Model Content

[0003] This utility model provides a waterproof and heat-insulating window installation node structure, which improves the waterproofness and sealing of the window while adding a drainage structure to prevent rainwater from accumulating at the bottom of the window frame.

[0004] To achieve these objectives and other advantages according to this utility model, a waterproof and heat-insulating window installation node structure is provided, including a window frame with a sub-frame between its bottom and the wall. The window frame is flush with the outer side of the wall, and the sub-frame is 30-60 mm away from the outer side of the wall. One side of the sub-frame is flush with the outer side of the wall by filling with thermal insulation mortar. The perimeter of the window on the wall is coated with waterproof paint, and the waterproof paint extends to the sub-frame. Foam is filled between the sub-frame and the wall, and between the window frame and the sub-frame. Sealant is applied to the gaps between the bottom two sides of the window frame and the wall.

[0005] Preferably, an insulation layer is provided around the window on the outside of the wall, and a drainage board with a downward slope of 3% to 5% facing the outside is provided on the bottom outside of the window frame. The bottom of the drainage board and the insulation layer are sloped by filling with insulation mortar.

[0006] Preferably, a decorative surface layer is provided on the outer side of the insulation layer, and the thickness of the decorative surface layer is 8~12 mm.

The extension direction of the multiple first drainage channels is parallel to the window frame, and the multiple second drainage channels are perpendicular to the multiple first drainage channels and connected to each other. The depth of the second drainage channels is greater than the depth of the first drainage channels.

[0009] Preferably, a siphon acceleration chamber is provided in the middle of each first drainage trough, and a hemispherical protrusion is provided inside the siphon acceleration chamber. A drainage pipe parallel to the second drainage trough is provided inside the drainage plate.

[0022] like Figure 1-4 As shown, this utility model provides a waterproof and heat-insulating window installation node structure, including a window frame 100, with a sub-frame 101 provided between its bottom and the wall 200. The window frame 100 is flush with the outer side of the wall 200. The sub-frame 101 is 30-60 mm away from the outer side of the wall 200, and one side of the sub-frame 101 is flush with the outer side of the wall 200 by filling with thermal insulation mortar 102. The periphery of the window of the wall 200 is coated with waterproof paint 103, and the waterproof paint 103 is applied to the sub-frame 101. Foam 104 is filled between the sub-frame 101 and the wall 200, and between the window frame 100 and the sub-frame 101. Sealant 105 is applied to the gaps between the bottom two sides of the window frame 100 and the wall 200.

[0023] In the above technical solution, the waterproof and heat-insulating window installation node structure mainly includes the following key components: Window frame 100, as the main frame of the window, is made of high-strength, corrosion-resistant material to ensure structural stability and durability. The bottom edge of the window frame 100 is designed with precise mating surfaces to facilitate a tight connection with the wall 200 and the sub-frame 101. The sub-frame 101 is installed between the bottom of the window frame 100 and the wall 200, and its material is usually matched with or has good compatibility with the window frame 100 to ensure the stability of the overall structure. The sub-frame 101 is designed with a width of 30-60 mm, this spacing is designed to provide an effective heat insulation and waterproof buffer zone. The window frame 100 and the sub-frame 101 are fixed with mounting nails, and the sub-frame is fixed to the wall with plastic expansion bolts 201. One side of the sub-frame 101 is specially designed to be flush with the outer surface of the wall 200 by filling with thermal insulation mortar 102, enhancing the building's thermal insulation performance. The wall 200 is the main structural component of the building. Its window perimeter is pre-coated with a high-quality waterproof coating 103. This coating not only covers the wall 200 itself but also extends to the surface of the subframe 101, forming a continuous waterproof barrier that effectively prevents rainwater penetration. High-performance thermal insulation mortar 102 is used to fill the gap between one side of the subframe 101 and the wall 200. This material not only provides excellent thermal insulation but also increases the overall structural stability. Expanding foam 104 is filled into the gaps between the subframe 101 and the wall 200, and between the window frame 100 and the subframe 101. After curing, the expanding foam 104 forms a dense foam layer, effectively isolating airflow, improving thermal insulation performance, and preventing moisture intrusion. The small gaps between the bottom sides of the window frame 100 and the wall 200 are sealed with high-quality sealant 105, ensuring good sealing even under the worst weather conditions. The waterproof coating 103 applied to the perimeter of the window and the surface of the subframe 101 on the wall 200, combined with the dual sealing effect of sealant 105 and expanding foam 104, forms a waterproof barrier, effectively preventing rainwater from seeping into the interior through the window installation joints and protecting the building's interior from water damage. The thermal insulation mortar 102 filling the space between the subframe 101 and the wall 200, along with the expanding foam layer between the window frame 100 and the subframe 101, and between the subframe 101 and the wall 200, together constitute a highly efficient thermal insulation system. These materials not only have excellent thermal resistance but also effectively block the convection of hot and cold air, significantly reducing energy loss and improving the building's energy efficiency ratio. The ingenious design of the subframe 101 and its tight connection with the wall 200 and the window frame 100 not only enhances the stability of the window installation but also, to a certain extent, disperses and resists the effects of external wind, earthquakes, and other natural forces, ensuring the safety of the window and the overall building.

[0024] In another technical solution, an insulation layer 300 is provided around the window perimeter on the outer side of the wall 200, and a drainage board 301 with a downward slope of 3% to 5% towards the outside is provided on the bottom outer side of the window frame 100. The bottom of the drainage board 301 and the insulation layer 300 are sloped together by filling with insulation mortar 102. In this technical solution, the insulation layer 300 can be made of high-density polystyrene board, rock wool board, or polyurethane foam board, etc. The installation of the insulation layer 300 not only enhances the insulation effect of the window and its surrounding area, but also significantly improves the thermal resistance performance of the entire wall 200, effectively blocking unnecessary heat transfer between indoors and outdoors. The drainage board 301 with a downward slope of 3% to 5% towards the outside is installed on the bottom outer side of the window frame 100. It is made of corrosion-resistant and wear-resistant materials to ensure that it can maintain good drainage performance even when exposed to the outdoor environment for a long time. The slope design of the drainage board 301 ensures that rainwater can be drained away from the window area quickly and smoothly, effectively preventing water accumulation. To further enhance the waterproofing effect of the drainage board 301, we filled the space between its bottom and the insulation layer 300 with insulation mortar 102 to create a slope. This measure not only ensures a tight contact between the drainage board 301 and the insulation layer 300, but also improves the waterproofing performance of the entire window installation node.

[0025] In another technical solution, a decorative surface layer 302 is provided on the outer side of the insulation layer 300, and the thickness of the decorative surface layer 302 is 8~12 mm. In this technical solution, the decorative surface layer 302 not only beautifies the building appearance, but also resists the erosion of the external environment, such as wind, rain, and sun exposure, thereby extending the service life of the window installation joint.

[0026] In another technical solution, the insulation layer 300 is a graphite polystyrene board with a thickness of 80-120 mm. In this technical solution, using a graphite polystyrene board as the insulation layer 300 effectively improves the insulation effect.

[0027] In another technical solution, the top of the drainage plate 301 is provided with multiple parallel first drainage channels 303 and multiple second drainage channels 304. The extension direction of the multiple first drainage channels 303 is parallel to the window frame 100, and the multiple second drainage channels 304 are perpendicular to the multiple first drainage channels 303 and interconnected, with the depth of the second drainage channels 304 being greater than the depth of the first drainage channels 303. In this technical solution, multiple parallel first drainage channels 303 and multiple second drainage channels 304 are provided on the top surface of the drainage plate 301 on the outer side of the bottom of the window frame 100, realizing the rapid and orderly discharge of rainwater, thereby further improving the drainage performance of the window installation node. The design of the multiple first drainage channels 303 ensures that rainwater can be smoothly guided into the drainage channels when flowing along the direction of the window frame 100, avoiding the phenomenon of rainwater accumulation around the window frame 100. The multiple second drainage channels 304 are perpendicular to and interconnected with the multiple first drainage channels 303. The design of these second drainage channels 304 converges rainwater from different directions onto the same drainage path, further improving drainage efficiency and orderliness. The first drainage channel 303 and the second drainage channel 304, through a well-designed interconnection, form a complete drainage network. This network not only ensures that rainwater can quickly and smoothly drain away from the window area but also avoids drainage problems caused by localized water accumulation. Furthermore, the interconnection design of the drainage channels takes into account the natural flow patterns of rainwater, ensuring a natural and efficient drainage process.

[0028] In another technical solution, a siphon acceleration chamber 305 is provided in the middle of each first drainage channel 303. A hemispherical protrusion 306 is provided within the siphon acceleration chamber 305. A drainage pipe 307 parallel to the second drainage channel 304 is provided inside the drainage plate 301. Multiple drainage holes 308 communicating with the drainage pipe 307 are opened on the bottom wall of each siphon acceleration chamber 305. A through hole 309 communicating with the drainage pipe 307 is opened on the top of each hemispherical protrusion 306. The top of each hemispherical protrusion 306 is higher than the bottom of the corresponding first drainage channel 303. In this technical solution, a siphon acceleration chamber 305 is provided within the first drainage channel 303 to accelerate rainwater discharge through the siphon effect, further improving the drainage performance of the window installation node. A hemispherical protrusion 306 is provided within the siphon acceleration chamber 305. When the rainfall increases and the water level in the first drainage trough rises to submerge the hemispherical protrusion 306, the rainwater can be quickly discharged into the drainage pipe 307 through the through hole 309 at the top of the shell, thereby improving drainage efficiency.

[0029] In another technical solution, the cross-section of each first drainage channel 303 and second drainage channel 304 is a trapezoidal structure. In this technical solution, the trapezoidal cross-section design can more effectively guide rainwater to flow along the channel, reduce the resistance of water flow in the channel, and improve drainage efficiency.

[0030] In another technical solution, the window frame 100 is made of aluminum, the subframe 101 is made of hot-dip galvanized material, and the thermal insulation mortar 102 is made of hydrophobic expanded polystyrene beads. In this technical solution, the use of an aluminum frame and a hot-dip galvanized subframe 101 improves the structural stability of the window, while the use of hydrophobic expanded polystyrene beads mortar 102 enhances thermal insulation performance.

[0031] In another technical solution, the waterproof coating 103 is a polyurethane waterproof coating, with a coating thickness of 1-2 mm. In this technical solution, the use of polyurethane waterproof coating improves waterproof performance.
