[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment of a window sill waterproof structure, including a concrete window sill 1. The material of the concrete window sill 1 is reinforced concrete. As the basic supporting structure, its thickness is not less than 200mm to ensure sufficient strength and durability. The addition of steel bars improves the tensile strength of the concrete, making the window sill more stable. This design ensures that the window sill can withstand the pressure from the window, wind pressure and possible water load for a long time without deformation or damage. The left and right sides of the interior of the concrete window sill 1 are slidably connected with expansion bolts 2. The top of the expansion bolts 2 is fixedly connected with a window frame 3. The material of the window frame 3 is aluminum alloy. Aluminum alloy has better weather resistance and corrosion resistance. The top of the concrete window sill 1 is in contact with the bottom end of the window frame 3, and the window frame 3 is in close contact with the top of the concrete window sill 1. The expansion bolt 2 is fixed to ensure the sealing and overall stability of the structure. A cavity structure 4 is opened inside the window frame 3 to provide additional heat insulation and sound insulation effects. The bottom end of the cavity structure 4 is fixedly connected with a trapezoidal groove 5. A waterproof mortar 6 is arranged inside the trapezoidal groove 5. The bottom end of the waterproof mortar 6 is in contact with the top of the concrete window sill 1. The trapezoidal groove 5 is located at the bottom end of the cavity structure 4 and is combined with the waterproof mortar 6. This design not only strengthens the connection between the window sill and the window frame 3, but also improves the waterproof performance. The left and right sides of the interior of the trapezoidal groove 5 are fixedly connected with an annular plate 7. The outside of the expansion bolt 2 is in contact with the inner wall of the annular plate 7. The function of the annular plate 7 is to increase the firmness of the expansion bolt 2 and prevent the bolt from rotating or moving under load, thereby improving the stability and durability of the entire window sill waterproof structure.

[0032] Reference Figure 3、 Figure 4 and Figure 5 , the left and right sides of the front of the cavity structure 4 are threaded with self-tapping screws 8, which connect the water-proof aluminum plate 9 to the cavity structure 4 inside the window frame 3, with a spacing of not less than 500mm, to ensure a firm connection between the water-proof aluminum plate 9 and the cavity structure 4 inside the window frame 3. The design of the self-tapping screw 8 simplifies the installation process because it can drill into the material and form a thread by itself, without the need for pre-drilling or using nuts. A sealant 10 is provided on the front of the self-tapping screw 8. The sealant 10 is made of polyurethane and is arranged on the outside of the self-tapping screw 8 to fill the gaps around the screws to prevent water from leaking through these small gaps. The outer wall of the self-tapping screw 8 is slidably connected to the water-proof aluminum plate 9, the thickness of which is not less than 2.5mm, and the slope is not less than 5%. This design is conducive to the smooth guidance of water flow to the outside, reducing the possibility of water accumulation. The surface of the water-proof aluminum plate 9 is treated with fluorocarbon spraying. This treatment method provides excellent weather resistance and corrosion resistance, and extends the service life of the aluminum plate. The front end of the cavity structure 4 is in contact with the rear end of the water-proof aluminum plate 9. The front side of the concrete window sill 1 is provided with a waterproof coating 11. The material of the waterproof coating 11 is a polymer waterproof coating with excellent adhesion and elasticity. It can expand and contract with the slight deformation of the concrete without cracking, maintaining the waterproof effect. The thickness of the coating is not less than 2mm to ensure sufficient waterproof layer thickness to resist water pressure and penetration. The bottom end of the water-proof aluminum plate 9 is provided with a drip groove 1 2. The drip groove 12 is semicircular with a radius of not less than 20mm. It is used to guide water flow and prevent water from flowing down the wall and causing damage. Structural adhesive 13 is provided inside the water-proof aluminum plate 9. The material of the structural adhesive 13 is silicone weather-resistant structural adhesive. The bottom end of the structural adhesive 13 is in contact with the top of the waterproof coating 11. The structural adhesive 13 has excellent weather resistance, UV resistance and long-term stability. The structural adhesive 13 is filled between the water-proof aluminum plate 9 and the waterproof coating 11, ensuring a close connection between the two. At the same time, it provides an additional protective layer for the entire window sill waterproof system, enhancing the overall waterproof performance.

[0033] Working principle: The concrete window sill 1 is a reinforced concrete window sill 1, which serves as the basic supporting structure and has a thickness of not less than 200mm to ensure sufficient strength and durability. The addition of steel bars increases the tensile strength of the concrete, making the window sill more stable. Lightweight and corrosion-resistant aluminum alloy materials are selected to make the window frame 3, which is fixed to the concrete window sill 1 through expansion bolts 2 to ensure the stability and sealing of the window frame 3. A trapezoidal groove 5 is provided between the concrete window sill 1 and the window frame 3 for filling with waterproof mortar 6 to form the first line of defense to prevent moisture penetration; a waterproof coating 11 is provided on the outside of the concrete window sill 1. The waterproof coating 11 is a polymer waterproof coating with a coating thickness of not less than 2mm. It serves as the second line of waterproofing to enhance the waterproof effect; a water-resistant aluminum plate 9 serves as the third line of waterproofing with a thickness of not less than 2.5mm. The surface is treated with fluorocarbon spraying, which not only increases the weather resistance and corrosion resistance of the aluminum plate, but also provides drainage. The slope is not less than 5%, which effectively guides rainwater to flow to the drip groove 12 to prevent water accumulation; the drip groove 12 is semicircular with a radius of not less than 20mm. It is located at the bottom of the water-proof aluminum plate 9 to guide water flow and prevent water from flowing down the wall and causing damage; the self-tapping screws 8 connect the water-proof aluminum plate 9 to the cavity structure 4 inside the window frame 3, with a spacing of not less than 500mm to ensure the stability of the connection; the sealant 10 is arranged on the outside of the self-tapping screws 8 to fill the gaps around the screws to prevent water from leaking through these small gaps; the structural adhesive 13 is a silicone weather-resistant structural adhesive, which is filled between the water-proof aluminum plate 9 and the waterproof coating 11. The structural adhesive 13 has good adhesion and weather resistance, and can further improve the waterproof performance of the overall structure. Through the combination of these design details, the windowsill water-proof waterproof structure can effectively prevent rainwater penetration, protect the interior of the building from water damage, and also improve the beauty and durability of the building.
