Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy building structure technology, specifically an aluminum alloy door and window watertight and seepage-proof structure. Background Technology

[0002] Water tightness is a crucial performance indicator for aluminum alloy doors and windows. Typically, water tightness is achieved through elastic sealing strips at the edges of the various profiles. These sealing strips are usually designed with a hollow, ring-shaped cross-section. When the edges of the aluminum profile compress and deform the sealing strip, the original gaps are filled, achieving a pressure seal. Furthermore, using multiple sealing strips from the outside to the inside, forming a multi-layered seal, results in even better water tightness.

[0003] However, in practical use, the pressure difference between indoor and outdoor air is the biggest obstacle to traditional watertight structures. Even with multiple layers of high-pressure sealing strips, the air pressure difference can still overcome the seals and seep into the room. Therefore, how to further enhance the watertightness and seepage prevention of aluminum alloy doors and windows remains a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] To solve the above problems, this utility model provides a watertight anti-seepage structure for aluminum alloy doors and windows, which is specially designed for watertight anti-seepage of aluminum alloy doors and windows. It changes the traditional watertight sealing method that uses high-pressure compression sealing, and has a good anti-seepage effect and is durable.

[0005] The specific solution of this utility model is as follows:

[0006] A watertight and seepage-proof structure for aluminum alloy doors and windows is provided, wherein the gap between the sash and the frame is sealed by a sliding sealing strip, and the gap between the sash and the subframe is sealed by a pressing sealing strip A and a pressing sealing strip B; rainwater flows from the outside to the inside, forming two chambers, watertight chamber A and watertight chamber B; rainwater passage holes are provided in the outer cavities of the sash and the subframe, and a drain one-way valve is provided on the outer wall of the frame.

[0007] In traditional sealing strategies, all joints along the rainwater path are sealed with compression-type sealing strips. This creates two low-pressure chambers, watertight chamber A and watertight chamber B. During heavy rain and wind outside, the air pressure in these two chambers is much lower than the outdoor air pressure. This causes watertight chamber A to tend to draw air (water) out through the joints, resulting in it filling with rainwater. Even if watertight chamber A has drainage holes, the internal pressure prevents proper drainage. When the rainwater volume in watertight chamber A reaches a certain level, the pressure difference between watertight chamber B and watertight chamber A causes watertight chamber B to draw air (water) into watertight chamber A through the gaps, ultimately allowing rainwater to enter the room from the outside.

[0008] In this invention, the outermost compression-type sealing strip is replaced with a sliding sealing strip. The sliding sealing strip is not pressed tightly against the edge of the profile, but rather allows for free contact and isolation. Two small notches are cut on both sides of the strip, ensuring that the air pressure in watertight cavity A is essentially the same as the outdoor air pressure, forming an isobaric cavity. During heavy rain and wind, the sliding sealing strip blocks most of the rainwater. A small amount of rainwater enters watertight cavity A and is easily drained to the outside through the rainwater passage holes in the outer cavity of the fan material and subframe. Rainwater cannot reach the gap between watertight cavity B and watertight cavity A, thus effectively preventing rainwater from entering watertight cavity B and achieving an indoor watertight seal.

[0009] Meanwhile, due to the slight deformation of the wind-pressure glass, rainwater seeps into the inner cavity of the fan material through the gaps in the glass sealant. Since the inner cavity of the fan material is connected to the airtight cavity A and the air pressure is equal, the rainwater will also flow out from the drainage holes of the fan material and will not seep into the gaps in the glass sealant inside.

[0010] The root of the sliding sealing strip is embedded in the mounting groove of the fan material, the head of the cantilever sliding part contacts the edge of the frame, and the head surface of the cantilever sliding part is provided with a guide coating.

[0011] The fan profile, frame, and subframe are all made of thermally broken aluminum, and are connected by a thermal insulation strip between two profiles. Thermal insulation strip A is installed in the middle of the fan profile, thermal insulation strip B is installed in the middle of the frame, and thermal insulation strip C is installed in the middle of the subframe.

[0012] The thermal break structure can effectively block heat between indoors and outdoors, resulting in better heat insulation.

[0013] The advantages of this utility model are:

[0014] 1. This utility model structure is specifically designed for watertight and seepage prevention of aluminum alloy doors and windows. It changes the traditional watertight sealing method that uses high-pressure compression. By using a sliding rubber strip for the first layer, the air pressure in the outermost watertight cavity is reduced, while also blocking most of the rainwater. This makes it easier for the rainwater in the outermost watertight cavity to drain, thereby protecting the inner watertight cavity from the effects of rainwater infiltration.

[0015] 2. This utility model adopts a drainage process of "staggered layering and staggered positioning" to increase the drainage stroke. Combined with a one-way valve drain cover, it solves the problems of rainwater backflow and whistling, and the watertight performance is more guaranteed.

[0016] 3. This utility model is easy to implement; it only requires replacing the sealing strip, making it highly practical. Attached Figure Description
