AI Technical Summary
In existing aluminum-clad plastic doors and windows, water tends to accumulate in the interlayer between the aluminum and plastic, leading to poor drainage. Furthermore, the expansion of water when it freezes can cause deformation of the aluminum and plastic.
Water storage gaps are made on the outer side of the PVC frame of the mullions, frames and sashes of aluminum-clad plastic doors and windows, and water troughs are connected to the inner surface of the outer aluminum material. The opening of the water trough is facing upward and located in the water storage gap. Combined with the drainage hole design, the water storage space is expanded and water is stored independently, which enhances the drainage effect.
It improves the drainage function of doors and windows, prevents water accumulation, prevents deformation of aluminum and plastic, keeps the building appearance clean, and extends the service life of doors and windows.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum-clad plastic doors and windows technology, specifically to an aluminum-clad plastic door and window with improved drainage function. Background Technology
[0002] In the construction industry, aluminum profiles are widely used in doors, windows, curtain walls, and other components. For doors and windows, rainwater infiltration is a critical issue. Especially in rainy areas or high-rise buildings, rainwater can seep into the interior through gaps in doors and windows or the surface of the profiles, leading to problems such as mold growth on walls and damage to interior finishes. Curtain walls, as an important component of the building facade, also face the challenge of rainwater drainage. Good drainage can prevent rainwater from accumulating inside the curtain wall, avoiding structural damage and leaks caused by water accumulation, extending the curtain wall's lifespan, and maintaining a clean building appearance.
[0003] In existing doors and windows, water tends to accumulate in the interlayer between aluminum and plastic, making it difficult for water to drain. When the water freezes, it expands and causes the aluminum and plastic to deform. This invention solves the above problems. Utility Model Content
[0004] This invention addresses the technical problem in existing doors and windows where water tends to accumulate in the interlayer between aluminum and plastic, making drainage difficult and causing deformation of the aluminum and plastic as the water freezes. The invention provides an aluminum-clad plastic door and window with improved drainage function.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum-clad plastic door and window with improved drainage function, comprising: a mullion, a frame, and a sash. The outer side of the plastic steel frame of the mullion and the frame is provided with a water storage gap. The plastic steel frame is covered with an outer aluminum material. A water trough is connected to the inner surface of the outer aluminum material. The opening of the water trough faces upward and is located in the water storage gap. A drainage hole is provided on the water trough.
[0006] Preferably, the mullion includes a plastic steel mullion frame, with a water storage notch on the outer side of the plastic steel mullion frame, and the outside of the plastic steel mullion frame is covered with an aluminum frame cladding material. A water tank is connected to the inner surface of the aluminum frame cladding material, with the opening of the water tank facing upward and located inside the water storage notch.
[0007] Preferably, the frame includes a plastic steel frame, a water storage gap two is provided on the outer side of the plastic steel frame, the plastic steel frame is covered with an outer aluminum frame material, and a water tank two is connected to the inner surface of the outer aluminum frame material, with the opening of the water tank two facing upward and located inside the water storage gap two.
[0008] Preferably, the fan includes a plastic steel fan frame and an aluminum cladding material for the fan frame. The plastic steel fan frame is covered with the aluminum cladding material for the fan frame, and the aluminum cladding material for the fan frame has a corner bracket cavity inside.
[0009] Preferably, when the mullion and frame plastic steel frame are not covered with outer aluminum material, auxiliary materials are snapped into the water storage gap.
[0010] Preferably, the edges of the mullion and frame plastic steel frame are integrally formed with a snap-fit platform, a rubber strip groove, and a pressure strip groove. The snap-fit platform is flush with the upper surface of the rubber strip groove and the pressure strip groove, and the snap-fit platform has multiple nail channels inside.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The water tank located within the water storage gap expands the water storage space and makes the water storage space independent. Water entering the water tank will not accumulate elsewhere, and the drainage effect is very good when combined with the drainage hole.
[0013] The snap-fit platform works in conjunction with the adhesive strip groove and pressure strip groove, making the connection of the adhesive strip and pressure strip more stable and aesthetically pleasing compared to the existing groove design. At the same time, the snap-fit platform can add multiple nail channels, enhancing the stability of the connection. Attached Figure Description
