[0025] Please refer to Figure 1 and Figure 2The utility model discloses an outer window sill waterproof board, which comprises a body 1, the body 1 comprises extrusion parts 11, extension parts 12 and water retaining parts 13 which are connected with each other, the extension parts 12 are used for being supported on a horizontally arranged window sill 103 and are connected to the window sill 103 through sealing glue 4, the extension parts 12 extend obliquely downwards away from a window frame 104, the extrusion parts 11 are connected to one end of the extension parts 12 close to the window frame 104 and extend longitudinally, and the extrusion parts 11 are connected to the window frame 104 through screws 6, the side surface of the extrusion parts 11 close to the window frame 104 is recessed to form a long strip-shaped glue storage groove 112 in the middle part, the glue storage groove 112 is used for filling the sealing glue 4, and the position of the screw 6 penetrating through the extrusion parts 11 corresponds to the glue storage groove 112, and the water retaining parts 13 are connected to one end of the extrusion parts 11 away from the extension parts 12 and extend longitudinally away from the extrusion parts 11.

[0026] Before installation, the excess sealing glue 4 is pre-filled in the glue storage groove 112, when the screw 6 is locked, the extrusion parts 11 gradually approach and abut against the window frame 104, and the excess sealing glue 4 in the glue storage groove 112 overflows and is filled in the gap between the extrusion parts 11 and the window frame 104, so that the sealing property between the extrusion parts 11 and the window frame 104 is enhanced. Since the position of the screw 6 penetrating through the extrusion parts 11 corresponds to the glue storage groove 112, the sealing glue 4 surrounds and adheres to the outer side of the screw 6 after solidification, so that the connecting force is enhanced and the screw hole is sealed. When the screw 6 is embedded in the window frame 104, a small amount of sealing glue 4 is also attached to the surface of the screw 6, so that the connection between the screw 6 and the window frame 104 is more closely and firmly.

[0027] In some embodiments, the end face of the end of the extrusion parts 11 away from the extension parts 12 is an end face 111, the thickness of the end face 111 is any value in the range of 4mm to 1cm, for example, can be any value in the range of 4mm, 6mm, 8mm and 1cm, and the end face 111 is connected to the window frame 104 through the sealing glue 4. By widening the end face 111, the end face 111 and the window frame 104 can be further sealed through the sealing glue 4, which helps to enhance the waterproof performance of the outer window sill waterproof board.

[0028] In some embodiments, the extrusion parts 11 further comprise a glue strip groove 113 for accommodating the sealing strip 3, the glue strip groove 113 is formed in the side surface of the extrusion parts 11 close to the window frame 104, the shape of the inner wall of the glue strip groove 113 is matched with the sealing strip 3, and the sealing strip 3 is constrained in the glue strip groove 113. The sealing property between the extrusion parts 11 and the window frame 104 is enhanced through the sealing strip 3, which helps to reduce the risk of gap between the extrusion parts 11 and the window frame 104 due to thermal expansion and cold contraction, suppresses the generation of cracks, and thus prolongs the service life of the outer window sill waterproof board.

[0029] In some embodiments, the sealing strip 3 is configured in a cylindrical shape, and the central angle of the inner wall of the glue strip groove 113 is greater than 180°, which helps to constrain the sealing strip 3 in the glue strip groove 113 and prevent the sealing strip 3 from falling off by itself.

[0030] In some embodiments, two glue strip grooves 113 are formed on the upper and lower sides of the glue storage groove 112 respectively, so that the sealant 4 in the glue storage groove 112 is easily attached to the surface of the sealing strip 3 when it overflows, which helps to improve the synergy between the sealing strip 3 and the sealant 4 and strengthen the sealing.

[0031] In some embodiments, the water blocking part 13 is formed with an anti-back water hook 131 at the end away from the extension part 12. The anti-back water hook extends towards the window frame 104 and then extends towards the extrusion part 11, preventing rainwater from flowing to the lower surface of the extension part 12 due to wind blowing, and improving the waterproof capability.

[0032] In some embodiments, the surface of the extension part 12 away from the window sill 103 is formed with anti-skid lines 121 to enhance the surface sliding friction and facilitate the placement of articles on the extension part 12, reducing the risk of articles falling.

[0033] In some embodiments, the outer window sill waterproof plate further comprises a baffle 2, and the end of the extension part 12 away from the extrusion part 11 is further connected with a female buckle 14. The baffle 2 comprises a plate body 21 and a sub-buckle 22 connected with each other. The sub-buckle 22 is matched with the female buckle 14 and can be detachably connected with the female buckle 14. The plate body 21 is longitudinally arranged and extends away from the water blocking part 13. By installing the baffle 2, the risk of articles placed on the extension part 12 falling is further reduced. The detachable connection of the baffle 2 with the body 1 facilitates the disassembly and storage of the baffle 2 in bad weather, preventing the baffle 2 from falling and causing safety hazards.

[0034] In some embodiments, the female buckle 14 is configured in a cylindrical shape, and its side surface is connected with and tangent to the extrusion part 11. The sub-buckle 22 is configured in a hook shape matched with the single-sided opening of the female buckle 14, and the opening of the sub-buckle 22 is smaller than the diameter of the female buckle 14. The body 1 can be connected with multiple baffles 2 at the same time. The baffle 2 is configured in a shorter structure, and only needs to be installed at the required position, which helps to improve the convenience of disassembling the baffle 2.

[0035] In some embodiments, the material of the body 1 is aluminum alloy, and the material of the baffle 2 is plastic, which has the advantages of low cost and easy availability.

[0036] For details, please refer to the following embodiments.

[0037] Embodiment one:

[0038] Please refer to Figure 1 and Figure 2 , the outer window sill waterproof plate shown in a preferred embodiment of the present application comprises a body 1 and multiple baffles 2 detachably connected with the body 1.

[0039] The body 1 comprises an extension 12 and a pressing portion 11 and a water-stopping portion 13 connected to both ends of the extension 12. The extension 12 is supported by a transversely arranged window sill 103 and extends towards the obliquely downward direction away from a window frame 104. The window sill 103 is formed by a concrete wall 101 and a thermal insulation layer 102 arranged on the outer surface of the wall 101. The extension 12 of the body 1 is connected to and supported by the window sill 103, and the surface of the extension 12 away from the extension 12 is formed with anti-skid lines 121 to prevent the articles placed on the surface of the extension 12 from sliding. In the embodiment, the anti-skid lines 121 comprise a plurality of rectangular grooves extending horizontally parallel to the window frame 104, and the anti-skid lines 121 are formed on the extension 12 away from the window frame 104 to reduce the accumulation of rainwater near the window frame 104. The pressing portion 11 is connected to one end of the extension 12 near the window frame 104 and extends in the direction matching the window frame 104. In the embodiment, the pressing portion 11 extends vertically. The thickness of the pressing portion 11 is 5 mm, the side surface of the pressing portion 11 away from the extension 12 is a horizontal end surface 111, and the thickness of the end surface 111 is equal to the thickness of the pressing portion 11 as a whole. A rectangular long-shaped glue storage groove 112 is formed in the middle of the side surface of the pressing portion 11 near the window frame 104, the glue storage groove 112 extends along the horizontal direction and penetrates the body 1. A glue strip groove 113 is formed above and below the glue storage groove 112, respectively, and penetrates the body 1. The glue strip groove 113 is symmetrical to the glue storage groove 112 and has the same structure. The inner wall of the glue strip groove 113 is arc-shaped, and the central angle is 250°, which is used to accommodate and constrain the cylindrical sealing strip 3 matched with the glue strip groove 113. In the embodiment, the sealing glue 4 is silicone glue, the sealing strip 3 is EPDM rubber strip, and the sealing strip 3 partially protrudes outside the glue strip groove 113. The water-stopping portion 13 is connected to one end of the extension 12 away from the window frame 104 and extends in the vertical direction away from the pressing portion 11. The water-stopping portion 13 is formed with a water-repelling hook 131 at one end away from the extension 12. The water-repelling hook extends towards the window frame 104 and then extends towards the pressing portion 11, forming a hook-shaped opening at the top, which prevents the rainwater attached to the water-stopping portion 13 from moving close to the connection between the extension 12 and the window sill 103 under the action of wind, thereby improving the waterproof performance.

[0040] In the installation of the body 1, two long strips of sealant 4 are arranged on both sides of the window sill 103 close to and away from the window frame 104, and the foaming glue 5 is filled between the two strips of sealant 4. After the sealing strip 3 is inserted into the glue strip groove 113, the excess sealant 4 is filled in the glue storage groove 112. The extension part 12 is bonded to the window sill 103, and the extrusion part 11 is bonded to the window frame 104. Due to the excess sealant 4 in the glue storage groove 112, when the extrusion part 11 is extruded on the window frame 104, the sealant 4 overflows and fills into the connecting joint. After positioning, the screw 6 is passed through the position corresponding to the glue storage groove 112 on the extrusion part 11 and embedded in the window frame 104 to strengthen the connection. The extension part 12 and the window frame 104 are sealed by the sealant 4 at the joint, so that the sealant 4 is connected with the window frame 104 and the end face 111, and the waterproof ability is improved.

[0041] The end of the extension part 12 away from the extrusion part 11 continues to extend and expand, and a cylindrical female buckle 14 is formed on the side of the water baffle 13 away from the extrusion part 11. The long strip-shaped female buckle 14 extends horizontally, and the two ends of the female buckle 14 are flush with the edges of the extension part 12, and the length of the female buckle 14 in the direction parallel to the window frame 104 is 3m.

[0042] The body 1 is integrally formed by pressure casting of aluminum alloy, and the exposed part of the surface is coated with a color consistent with the outer surface of the thermal insulation board, thereby improving the aesthetic appearance. In this embodiment, the surface of the extension part 12 of the body 1 away from the window sill 103, the surface of the extrusion part 11 away from the window frame 104, the end face 111, the whole water baffle 13 and the whole female buckle 14 are white by painting.

[0043] The baffle 2 is integrally constructed by a hard polyvinyl chloride (PVC) plate, including a plate body 21 and a female buckle 22 connected to each other. The female buckle 22 is configured in a hook shape matched with the female buckle 14, and the opening of the female buckle 22 is smaller than the diameter of the female buckle 22, so as to constrain the female buckle 14. The female buckle 22 is sleeved outside the female buckle 14 by its elasticity, realizing detachable connection. The plate body 21 is integrally configured in a rectangular plate structure, and is connected to the edge of the opening of the female buckle 22. The end of the plate body 21 away from the female buckle 22 extends vertically towards the window frame 104 to form a blocking part 211. When the baffle 2 is connected to the female buckle 14, the plate body 21 is arranged in the vertical direction. The length of the baffle 2 in the horizontal direction parallel to the window frame 104 is smaller than the body 1, so that the same body 1 can be connected to multiple baffles 2 at the same time. In this embodiment, the length of the baffle 2 in the horizontal direction parallel to the window frame 104 is 50cm, facilitating installation and disassembly. The baffle 2 is used to block the articles placed on the extension part 12 from falling off. When encountering severe weather such as storm, the articles placed on the extension part 12 need to be transferred to the indoor, and the baffle 2 is disassembled to prevent the articles or the baffle 2 from falling off and causing safety hazards.
