Description

Technical Field

[0001] The utility model relates to the technical field of building door and window waterproofing, in particular to a window sill board for enhancing the waterproof performance of doors and windows. Background Art

[0002] With the continuous development of modern building technology and the improvement of people's requirements for living environment, doors and windows, as an important part of buildings, their waterproof performance has received more and more attention. Especially in rainy and humid areas, the waterproof performance of doors and windows is directly related to the dryness and comfort inside the building. However, after the existing doors and windows are installed, the outdoor waterproof problem has always existed.

[0003] The window sill board is a decorative and functional component around the window. It is usually located on the horizontal plane below the window and sometimes can also extend to the vertical plane of the wall. The main function of the window sill board is to protect the window sill, prevent rainwater from entering the room, and at the same time can also serve as a buffer between the window frame and the wall surface, reducing the possible wear caused by their direct contact. In addition, the window sill board also has a certain decorative effect, which can improve the overall beauty of the window. Traditional window sill board designs often have problems with insufficient waterproof performance. Especially when the rain is heavy or the wind direction is unfavorable, rainwater is likely to penetrate into the room through the window sill board, resulting in damp and moldy walls, and even affecting the service life of indoor furniture and electrical appliances.

[0004] The existing patent CN211397170U discloses a window sill board for leak-proof and energy-saving doors and windows. A sealing gasket is arranged between the window sill board and the sub-frame; one side of the sealing gasket is in contact with the sub-frame surface; the other side of the sealing gasket is in contact with the window sill board surface; the window sill board, the sealing gasket and the sub-frame are connected by bolts. Although the sealing gasket of the above structure improves the waterproof performance to a certain extent, since the window sill board and the window frame are fixedly installed by bolts, there will inevitably be gaps between the window sill board and the window frame, and rainwater is easy to seep in along the gaps. Moreover, the bolts damage the sealing performance of the window frame, and rainwater is also easy to seep in along the gaps at the bolt installation positions. Therefore, the above window sill board for energy-saving doors and windows cannot achieve effective window sill waterproofing during actual installation and use. Content of the Utility Model

[0033] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the drawings as follows:

[0034] Embodiment 1: As Figure 1 and Figure 2 shown, the sill plate includes a sill plate body 1. The sill plate body is made of stainless steel material with a thickness of 2 mm. The sill plate body 1 is provided with two bends. One end of the sill plate body 1 connected to the window frame 2 is provided with a first bend 4, and the other end of the sill plate body 1 is provided with a second bend 5. The design of the two bends enables the sill plate to better guide the water flow when impacted by rainwater and prevent rainwater accumulation.

[0035] One end of the window sill body 1 is provided with a snap structure 3 that can be connected to the window frame 2. The snap structure 3 includes a snap bend 31 and an anti-slip protrusion 32. The snap bend matches the slot on the window frame to achieve a tight connection through snapping. The anti-slip protrusion increases the friction between the snap structure and the window frame to prevent the window sill from falling off during use.

[0036] Sealing devices are provided at both ends of the window sill body 1, and the sealing device 6 includes a first protrusion 61, a second protrusion 62 and a third protrusion 63. The first protrusion 61 is provided at one end of the window sill body 1 close to the window frame 2, and the first protrusion 61 is sealed to the window frame 2 by sealant or silicone. The second protrusion 62 and the third protrusion 63 are provided at one end of the window sill body 1 away from the window frame 2, and the second protrusion 62 and the third protrusion 63 are sealed to the window sill by filling with sealant.

[0037] Preferably, the bottom surface of the window sill body 1 is fixedly connected to the window sill 8 by means of sealant, thereby ensuring a seamless connection between the window sill and the window sill, and further improving the waterproof performance.

[0038] Preferably, the outer surface of the window sill body 1 is set as a downward inclined surface, and the angle between the inclined surface and the horizontal plane is set to 10°, which increases the diversion function of rainwater, allows rainwater to slide down quickly, improves the discharge efficiency of rainwater, and prevents water accumulation.

[0039] In addition, if Figure 3 As shown, the outer surface of the window sill body 1 is also coated with a layer of waterproof coating 7 to increase the waterproof performance of the window sill and extend its service life. The waterproof coating adopts environmentally friendly polyurethane waterproof coating, which has excellent weather resistance, water resistance and chemical corrosion resistance.

[0040] Preferably, the window sill body 1 is an inverted L-shaped structure as a whole, which is convenient for installation and use.

[0041] Embodiment 2: The window sill comprises a window sill body 1, which is made of 3mm thick stainless steel or aluminum alloy material to meet the load-bearing requirements of a specific window. The window sill body is provided with three bends to adapt to the complex structure of the window.

[0042] The buckle structure at one end of the window sill adopts a double buckle design, including two side-by-side buckle bends and an anti-slip protrusion. This design increases the connection points between the window sill and the window frame, and improves the stability and waterproof performance of the connection.

[0043] like Figure 4 As shown, this embodiment further adds plugs 9 on both sides of the window sill body. The plugs are made of highly elastic rubber material and can fit tightly with the window sill body to prevent rainwater from overflowing.

[0044] In addition, to increase the bearing capacity of the window sill board, reinforcing ribs are added inside the window sill board body in this embodiment. The reinforcing ribs are made of stainless steel and are fixedly connected to the window sill board body by welding. The addition of the reinforcing ribs not only improves the strength of the window sill board but also makes it more stable.

[0045] In terms of the waterproof coating, this embodiment adopts a double-layer waterproof coating design. The bottom layer uses epoxy resin waterproof coating, which has good adhesion and water resistance; the upper layer uses polyurethane waterproof coating, which has excellent weather resistance and chemical corrosion resistance. The design of the double-layer waterproof coating further enhances the waterproof performance of the window sill board.

[0046] The outer surface of the window sill board body 1 is set as an inclined plane that slopes downward, and the angle between the inclined plane and the horizontal plane is set to 13.5°, which is more suitable for a specific window sill, increases the discharge of rainwater, and prevents the accumulation of rainwater on the window sill board body.

[0047] In practical applications, the window sill and the window frame are fixedly connected through the window sill board body. Sealant is evenly applied around the outer edge of the window sill, and polyurethane foam is filled in the middle of the window sill. The window sill board fits the sealant and the foaming agent to be fixedly connected to the window sill. One end of the window sill board body 1 is provided with a snap structure 3 that can be connected to the window frame 2, and sealing devices 6 are also provided at both ends of the window sill board body 1. The window sill board body 1 is provided with multiple bends. The window sill board body 1 is hermetically connected to the window frame 2 and the window sill 8 through the snap structure 3 and the sealing device 6 respectively, improving the sealing performance of the connection and preventing the backflow of rainwater. The setting of multiple bends increases the friction between the window sill board body and the window sill, improves the stability of the window sill board, and extends the service life of the window sill board.

[0048] One end of the window sill board body is provided with a snap structure, which is snap-connected to the window frame through the snap bending. The anti-slip protrusions prevent the displacement of the window frame, further enhancing the sealing performance of the connection between the window frame and the window sill board, preventing the leakage of rainwater, and improving the waterproof performance of the window sill board. The adoption of the snap structure can also adapt to various door and window structures, is convenient for installation, and improves the adaptability of the window sill board.

[0049] The sealing device includes a first protrusion, a second protrusion, and a third protrusion. A first protrusion is provided at one end of the window sill board body close to the window frame. Sealant is filled between the first protrusion and the snap structure to prevent the displacement of the window frame. The first protrusion has a heightened design to prevent the overflow of the sealant, further enhancing the stability and connection tightness of the window sill board, achieving a better sealing effect, preventing the infiltration of rainwater, and improving the waterproof performance of the window sill board.

[0050] The outer surface of the window sill board body 1 is an inclined plane that slopes downward, and the angle between the inclined plane and the horizontal plane is 5° to 15°, increasing the diversion function of rainwater, enabling the rainwater to slide down quickly, improving the discharge efficiency of rainwater, and preventing water accumulation.

[0051] A seal is added to the outer edge of the window sill plate body 1 to further prevent rainwater from splashing outwards and avoid polluting the wall surface.

[0052] The window sill plate body 1 can be sprayed with different colors to better match the colors of the window frame 2 and the window sill 8. The window sill plate body 1 can be made of the same material as the doors and windows, making the doors, windows and window sill plate more integral and aesthetic.
