Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a water-blocking structure for an aluminum alloy window sill. Background Technology

[0002] With the upgrading of product quality in the residential market and the increasing aesthetic demands of homeowners, the refined design of building facades has become an important evaluation dimension for quality residences. Currently, the construction of exterior window sills generally adopts the traditional process system of "concrete base + waterproof material + insulation material (northern regions)" / "concrete base + waterproof material (southern regions)". This traditional process for exterior window sill construction does not form an overall crack-resistant structural system, resulting in a high risk of rainwater infiltration.

[0003] When using traditional plastering mortar as a protective layer, the following problems are likely to occur after a 5-8 year service life due to long-term temperature and humidity cycles, ultraviolet radiation, and other environmental factors:

[0004] Mortar layer deterioration: Ordinary cement-based mortar has insufficient crack resistance, and a network of cracks gradually appears on the surface, which in turn leads to mortar peeling off;

[0005] Waterproofing material failure: After the protective layer is damaged, the waterproofing material is directly exposed to the natural environment, which accelerates aging (such as embrittlement of the roll material and cracking of the coating), creating a risk of leakage.

[0006] High maintenance costs: The defects are distributed in a continuous pattern, requiring complete dismantling and repair. Utility Model Content

[0007] The purpose of this invention is to provide a water-blocking structure for aluminum alloy window sills with more reliable waterproofing.

[0008] The purpose of this utility model is achieved as follows.

[0009] A water-blocking structure for an aluminum alloy window sill includes a window sill and an aluminum alloy window installed on the window sill. An aluminum alloy water-blocking plate is provided on the outer side of the bottom of the aluminum alloy window. An aluminum alloy connecting member is provided on the window sill corresponding to the aluminum alloy water-blocking plate. The bottom of the aluminum alloy connecting member is fixedly connected to the window sill. The outer ends of the aluminum alloy connecting member and the aluminum alloy water-blocking plate are sealed together. A first cavity is formed between the aluminum alloy connecting member and the aluminum alloy water-blocking plate. The gap between the aluminum alloy connecting member and the window sill is filled with a weather-resistant sealant layer.

[0010] Furthermore, the first cavity is filled with an insulation layer. This improves the thermal insulation effect and is mainly suitable for northern regions.

[0011] Furthermore, the aluminum alloy connecting component includes a first component. The bottom of the first component is connected and fixed to the windowsill via nails. The first component has a support portion extending outward from the aluminum alloy baffle, and a first limiting portion is provided on the inner side of the support portion. The bottom surface of the aluminum alloy baffle has a first slot, and the end of the first limiting portion is inserted upward into the first slot, forming the first cavity between the first component and the aluminum alloy baffle. The first component supports the aluminum alloy baffle and forms the first cavity, facilitating the installation of the insulation layer.

[0012] Furthermore, the aluminum alloy connecting component includes a second component. The top outer side of the first component has a second slot, and the bottom outer side of the first component has a third slot. The top of the second component has a first fastener, which is fastened to the second slot. The bottom inner end of the second component has a second fastener, which is fastened to the third slot. The top and bottom of the second component form inclined water-guiding slopes. A second cavity is formed between the second component and the first component. The gap between the bottom outer end of the second component and the windowsill is filled with the weather-resistant sealant layer. The second cavity improves waterproofing and insulation.

[0013] This utility model's aluminum alloy water-blocking plate and aluminum alloy connecting components serve as both a protective layer, resisting corrosion from ultraviolet rays and acid rain through the oxide film on the aluminum alloy surface, exhibiting no powdering or fading during its service life, outstanding impact resistance, and no risk of surface cracking under normal use conditions; and a waterproof layer. The modular installation of the aluminum alloy connecting components forms a complete protective system, requiring no regular maintenance. Attached Figure Description

[0015] Figure 2 for Figure 1 Enlarged diagram of A in the middle. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1, see Figure 1-2 As shown, a water-blocking structure for an aluminum alloy window sill includes a window sill 1 and an aluminum alloy window 2 installed on the window sill 1. An aluminum alloy water-blocking plate 3 extends horizontally outward from the bottom outer side of the aluminum alloy window 2, and an aluminum alloy connecting member 4 is provided on the window sill 1 corresponding to the aluminum alloy water-blocking plate 3.

[0018] The aluminum alloy connecting component 4 includes a first component 5 and a second component 6. The windowsill 1 is typically a concrete structure, which, after trimming, surface cleaning, and layout positioning, is fixed to the windowsill 1 at its bottom by nails 7, and then the aluminum alloy window 2 is installed. The first component 5 has a support portion 51 extending outwards from the aluminum alloy baffle 3. A first limiting portion 52 is located inside the support portion 51. A first slot 31 is located on the bottom surface of the aluminum alloy baffle 3. The end of the first limiting portion 52 is inserted upwards into the first slot 31, forming a first cavity 41 between the first component 5 and the aluminum alloy baffle 3. To improve thermal insulation, the first cavity 41 is filled with an insulation layer 8, as is the case in northern regions.

[0019] The first component 5 has a second slot 53 on its outer top and a third slot 54 on its outer bottom. The second component 6 has a first buckle 61 on its top, which is fastened to the second slot 53. The second component 6 has a second buckle 62 on its bottom inner end, which is fastened to the third slot 54. The top and bottom of the second component 6 form an inclined water-guiding slope 63. A second cavity 42 is formed between the second component 6 and the first component 5. The gap between the bottom outer end of the second component 6 and the window sill 1 is filled with a weather-resistant sealant layer 9. In this embodiment, the joint is sealed with weather-resistant sealant. The weather-resistant sealant layer 9 is a silicone weather-resistant sealant layer 9.

[0020] This utility model uses aluminum alloy connecting components 4 as a protective and waterproof layer, which facilitates the filling of the internal insulation layer 8, integrating the functions of insulation, waterproofing, and protection into a unified system. It has the advantages of waterproof reliability, insulation continuity, and decorative integrity. It is suitable for the integrated structure of the exterior window sill 1 of the building, reducing the loss of process connection. Through the matching combination of the protective ability of aluminum alloy and the insulation layer 8, it can adapt to structural displacement and changes in environmental temperature difference.
