Description

Technical Field

[0001] This application relates to the field of doors and windows, and more particularly to an aluminum alloy door and window structure. Background Technology

[0002] With the continuous development of the door and window industry, the design requirements for doors and windows are gradually increasing, especially the requirements for heat insulation and sound insulation performance. Current aluminum alloy doors and windows include fixed window frames, movable sash frames, and sealing components. The fixed window frame is fixed to the wall or a fixed structure. The fixed window frame and the movable sash frame are connected at one end by a metal fitting. The sealing components are located between the fixed window frame and the movable sash frame for sealing and heat insulation. The sealing components include a pair of edge sealing components. These edge sealing components are located at the edges of the fixed window frame and the movable sash frame, achieving edge sealing between the fixed window frame and the movable sash frame of the aluminum alloy door and window. Because aluminum alloy doors and windows are relatively thin compared to building walls, their sound insulation and heat insulation effects are not significant. Sound can enter the room through the gaps between the doors and windows, failing to reduce noise. Summary of the Invention

[0003] In order to improve the sound insulation and heat insulation performance of doors and windows, this application provides an aluminum alloy door and window structure.

[0004] The aluminum alloy door and window structure provided in this application adopts the following technical solution:

[0005] An aluminum alloy door and window structure includes a fixed window frame, a movable window sash, and an insulated glass fixed inside the movable window sash. The movable window sash includes an interior connecting profile, an exterior connecting profile, and a first thermal insulation strip connecting the interior connecting profile and the exterior connecting profile. The interior connecting profile and the exterior connecting profile are each connected to a piece of glass.

[0006] The fixed window frame includes an outdoor fixed frame and an indoor fixed frame, and a second thermal insulation strip is fixed to the outdoor fixed frame and the indoor fixed frame;

[0007] The outdoor fixed frame extends inward to form a first stop plate, and the indoor connecting profile extends outward to form a second stop plate. A third heat insulation strip is pressed between the first stop plate and the second stop plate.

[0008] By adopting the above technical solution, a first thermal insulation strip is installed on the movable window sash to connect the indoor and outdoor aluminum alloy frame materials, and a second thermal insulation strip is installed on the fixed window frame to connect the indoor and outdoor aluminum alloy frame materials. This doubles the thermal insulation and sound insulation effects of the aluminum alloy doors and windows. By setting the first stop plate and the second stop plate, the gap between the movable window sash and the fixed window frame can be tightly blocked on the indoor and outdoor sides. Furthermore, a third thermal insulation strip is added between the first stop plate and the second stop plate to further eliminate the gap between the movable window sash and the fixed window frame, reduce the convection of indoor and outdoor air, and enhance the sound insulation and thermal insulation effects of the aluminum alloy doors and windows.

[0009] Preferably, the first heat insulation strip includes two main heat insulation strips on both sides, a first interlocking strip integrally formed on one of the main heat insulation strips, and a second interlocking strip integrally formed on the other main heat insulation strip, wherein the first interlocking strip and the second interlocking strip interlock in a U-shape.

[0010] By adopting the above technical solution, the first heat insulation strip is set as a split type, and the first interlocking strip and the second interlocking strip are interlocked in a U-shape. This not only gives the first heat insulation strip a certain amount of deformation holes, which facilitates the blocking of air by its own deformation when indoor and outdoor air convection occurs, thus improving the heat insulation effect, but also makes it easier to enhance the connection strength between the first interlocking strip and the second interlocking strip. The sealing, heat insulation and sound insulation effects of the first heat insulation strip are better.

[0011] Preferably, the end of the first bite bar forms a U-shaped cavity, and the end of the second bite bar is provided with a connector placed in the U-shaped cavity. The cross-section of the connector is trapezoidal, a protrusion is formed on the inner wall of the first bite bar, and a groove corresponding to the protrusion is formed on the side wall of the connector.

[0012] By adopting the above technical solution, a solid trapezoidal connector is provided at the end of the first interlocking strip and is located in the U-shaped cavity at the end of the first interlocking strip. This reduces the effect of the connector coming out of the U-shaped cavity and improves the interlocking force between the first interlocking strip and the second interlocking strip. By providing protrusions and grooves on the inner wall of the first interlocking strip and the connector respectively, when the first heat insulation strip is subjected to indoor and outdoor convection impact force, the interlocking force of the protrusions and grooves is used again at the U-shaped interlocking part to enhance the sealing and heat insulation and sealing and sound insulation effect of the first heat insulation strip.

[0013] Preferably, two first thermal insulation strips are arranged in the direction from the outdoor side to the indoor side, and the first interlocking strip and the second interlocking strip are arranged with one being longer than the other, and the two first thermal insulation strips are arranged in opposite directions.

[0014] By adopting the above technical solution, the indoor and outdoor convective air is blocked by a double-layer deflector, which further improves the heat insulation and sound insulation effect of the aluminum alloy doors and windows of this application.

[0015] Preferably, the second heat insulation strip comprises two parallel strips, with a cavity formed between the two second heat insulation strips, and the first stop plate is equipped with a water-stopping component.

[0016] By adopting the above technical solution, when the movable window sash is opened, the second thermal insulation strip is exposed to the outside. When it rains outside, some rainwater may accumulate inside the fixed window frame. Installing a water-stop component on the first stop plate makes it easier to drain the water when there is water accumulation on the fixed window frame, thereby improving the sealing effect of the second thermal insulation strip.

[0017] Preferably, the water-stopping component includes a water-absorbing element that engages with the inner side of the first baffle plate and abuts against the upper surface of the second heat insulation strip, and a draining element disposed on the outer side of the first baffle plate and communicating with the water-absorbing element. The water-absorbing element extends through the first baffle plate to the outdoor side, and the draining element wraps around the water-absorbing element. The lower surface of the draining element has a plurality of drain holes. The draining element is an elastic element with a set elastic force and is used to squeeze the water inside the water-absorbing element after the water-absorbing element absorbs water and expands.

[0018] By adopting the above technical solution, the water accumulated on the second heat insulation strip is absorbed by the water-absorbing component inside the first baffle plate. As the water absorbed by the absorbent component gradually increases, the water-absorbing component bulges outward toward the outdoor side of the first baffle plate and squeezes the elastic drainage component outward. Under the action of elastic restoring force, the drainage component squeezes the water-absorbing component in the opposite direction, so that the water in the water-absorbing component is squeezed out and discharged from the drain at the bottom, thus realizing self-drainage.

[0019] Preferably, the third heat insulation strip includes a blocking part that engages with the inner side of the first stop plate and a locking part that engages with the inner side of the second stop plate. The end of the blocking part is provided with a blocking block for engaging with the locking part, and the two sides of the blocking block are provided with clamping strips for holding the main body of the locking part together after the locking part engages with the blocking block.

[0020] By adopting the above technical solution, there is a certain adhesive force between the barrier block and the locking part. When the movable window sash is closed, the impact force between the barrier block and the locking part is used to make the clamping strip lock the locking part. Without affecting the free opening and closing of the movable window sash, the sealing effect between the movable window sash and the fixed window frame when closed is improved, and the sound insulation and heat insulation performance of the aluminum alloy doors and windows of this application are further improved.

[0021] Preferably, the end of the locking part has a bowl-shaped retaining body, and both the retaining body and the blocking block are made of soft magnetic material.

[0022] By adopting the above technical solution, a bowl-shaped clamping body is set to combine with the barrier block, so as to increase the contact area with the barrier block and ensure the contact effect. Furthermore, both the clamping body and the barrier block are made of soft magnetic material, which can not only improve the adsorption effect between the clamping body and the barrier block, but also has almost no impact when the movable window sash is opened and closed.

[0023] Preferably, two clamping strips are symmetrically arranged, each clamping strip being an inwardly curved body with gradually decreasing thickness. The main body of the blocking part is formed with a corrugated contraction section, and the two clamping strips are arranged on the corrugated contraction section. The two clamping strips are used to clamp the locking part when the corrugated contraction section is impacted and contracted by the blocking block and the locking part.

[0024] By adopting the above technical solution, when the locking part and the blocking block collide and close the movable window sash, the impact force causes the corrugated contraction section to contract. Since the clamping strip is an inwardly curved body with a thickness that gradually decreases from near the corrugated contraction section to far away from the corrugated contraction section, when the corrugated contraction section contracts, the clamping strip continues to clamp inward to hold the main body of the locking part, thereby improving the sealing effect of the third thermal insulation strip.

[0025] Preferably, a dustproof adhesive strip for sealing with the indoor fixed frame is fixed to the bottom inner side of the second stop plate.

[0026] By adopting the above technical solutions, the sealing and dustproof effects of the aluminum alloy doors and windows in this application are enhanced.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. This application achieves triple sealing of the aluminum alloy doors and windows by setting thermal insulation strips inside the movable window sash and the fixed window frame, and setting a third thermal insulation strip to seal the movable window sash and the fixed window frame together, which effectively increases the thermal insulation and sound insulation effect of the aluminum alloy doors and windows.

[0029] 2. By setting the first thermal insulation strip as a split type, and making the first interlocking strip and the second interlocking strip interlock in a U-shape, it is not easy for indoor air to flow out or outdoor air to enter, reducing indoor and outdoor air convection, enhancing the sealing, heat insulation and sound insulation effect of the first thermal insulation strip, and the first thermal insulation strip has a certain deformation margin, which makes it easy to use its own deformation to block indoor and outdoor air convection.

[0030] 3. By setting a corrugated contraction section in the main body of the barrier and placing the clamping strip on the corrugated contraction section, when the movable window sash is closed, the corrugated contraction section contracts when the locking part collides with the barrier block, thereby triggering the clamping strip to clamp inward and clamp the main body of the locking part, thus improving the sealing effect between the movable window sash and the fixed window frame.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses an aluminum alloy door and window structure. (Refer to...) Figure 1 and Figure 2The aluminum alloy door and window structure includes a fixed window frame 2 fixed to the wall, a movable window sash 1 hinged to the fixed window frame 2, and double-glazed glass 14 fixedly sealed within the movable window sash 1. The movable window sash 1 includes an interior connecting profile 11, an exterior connecting profile 12, and a first thermal break strip 13 connecting the interior connecting profile 11 and the exterior connecting profile 12. The interior connecting profile 11 and the exterior connecting profile 12 each connect to a pane of glass, forming a cavity between the two panes of glass, and each pane of glass is connected to the movable window sash 1 by a sealing strip. The fixed window frame 2 includes an interior fixed frame 21 and an exterior fixed frame 22, with a second thermal break strip 23 fixed between the interior fixed frame 21 and the exterior fixed frame 22. The exterior fixed frame 22 extends inward to form a first stop plate 221, and the interior connecting profile 11 extends outward to form a second stop plate 111, to block the gap between the fixed window frame 2 and the movable window sash 1 on the interior and exterior sides. A third thermal break strip 3 is pressed between the first stop plate 221 and the second stop plate 111. The third thermal break strip 3 is a separate piece, which does not affect the opening of the movable window sash 1 and can also achieve a sealing effect with the fixed window frame 2 when the movable window sash 1 is closed. When the movable window sash 1 is closed, a triple sealing effect can be achieved through the first thermal break strip 13 inside the movable window sash 1 itself, the second thermal break strip 23 inside the fixed window frame 2 itself, and the third thermal break strip 3 used to seal the movable window sash 1 and the fixed window frame 2, effectively enhancing the heat insulation and sound insulation effect of aluminum alloy doors and windows.

[0039] Reference Figure 2 and Figure 3 Furthermore, the first heat insulation strip 13 includes two main heat insulation strips 131 on both sides, a first interlocking strip 132 integrally formed on one of the main heat insulation strips 131, and a second interlocking strip 133 integrally formed on the other main heat insulation strip 131. Both the first interlocking strip 132 and the second interlocking strip 133 are perpendicular to the main heat insulation strip 131. The end of the first interlocking strip 132 is bent in a U-shape to form a U-shaped cavity 135, and the end of the second interlocking strip 133 is also bent in a U-shape and provided with a connector 134 for placement within the U-shaped cavity 135, so that the first interlocking strip 132 and the second interlocking strip 133 interlock in a U-shape. Preferably, the connector 134 is made of solid material, and its cross-section is trapezoidal. This means the weight at the bottom of the U-shaped cavity 135 is greater than the weight at the top, reducing the probability of the connector 134 detaching from the cavity 135. A protrusion 136 is formed on the inner wall of the first interlocking strip 132, and a groove 137 corresponding to the protrusion 136 is formed on the side wall of the connector 134. The interlocking action of the protrusion 136 and the groove 137 further reduces the probability of the connector 134 detaching. Furthermore, when the first interlocking strip 132 and the second interlocking strip 133 are subjected to indoor and outdoor air convection, they can also use their deformation to block outdoor air from entering the room, achieving excellent heat insulation and sound insulation effects.

[0040] To further improve the sealing effect of the first thermal insulation strip 13, two first thermal insulation strips 13 are provided along the direction from the outdoor side to the indoor side. Furthermore, the first interlocking strip 132 and the second interlocking strip 133 are arranged with one long and one short, and the two first thermal insulation strips 13 are arranged in opposite directions to form a Z-shaped deflection between the two first thermal insulation strips 13, thereby enhancing the blocking effect on outdoor and indoor air and improving the thermal insulation and sound insulation effect of the aluminum alloy doors and windows of this application.

[0041] The second thermal break strip 23 includes at least two parallel strips, with a cavity formed between them. Specifically, this application uses the example of two second thermal break strips 23 spaced apart on the fixed window frame 2 from the wall side to the back wall side. When the movable window sash 1 is opened, the second thermal break strips 23 are exposed to the outside. When it rains outside, some rainwater may accumulate inside the fixed window frame 2, and a water-stopping component 4 is installed on the first stop plate 221. To facilitate water drainage, the second thermal break strip 23 gradually decreases in elevation from the indoor side to the outdoor side, and one side of the second thermal break strip 23 abuts against the water-draining component. This allows the slope of the upper surface of the second thermal break strip 23 to drain the accumulated water inside the fixed window frame 2 to the water-stopping component 4, reducing the probability of water accumulating in the fixed window frame 2 and affecting the sealing effect of the movable window sash 1.

[0042] Reference Figure 1 and Figure 4 The water-stopping component 4 includes a water-absorbing element 41 that engages with the inner side of the first stop plate 221 and abuts against the upper surface of the second heat insulation strip 23, and a drain element 42 that is disposed on the outer side of the first stop plate 221 and communicates with the water-absorbing element 41. The water-absorbing element 41 extends through the first stop plate to the outdoor side, and the drain element 42 is an elastic element with a set elastic force, which wraps around the water-absorbing element 41, and the lower surface of the drain element 42 has several drain holes 421. When the water-absorbing element 41 absorbs water and expands, the drain element 42 can use the restoring force generated by its own elastic deformation to squeeze the water inside the water-absorbing element 41, so that the water in the water-absorbing element 41 is discharged from the drain holes 421. By setting the drain holes 421 only on the lower surface of the drain element 42, the probability of external water entering is reduced. Preferably, the water-absorbing element 41 of this application is made of water-absorbing sponge, and the drain element 42 is made of elastic rubber material.

[0043] Reference Figure 5The third heat insulation strip 3 includes a blocking part 31 that engages with the inner side of the first stop plate 221 and a locking part 32 that engages with the inner side of the second stop plate 111. The end of the blocking part 31 is provided with a blocking block 311 for engaging with the locking part 32. The end of the locking part 32 is integrally formed with a bowl-shaped clamping body 321. The clamping body 321 impacts the blocking block 311 to increase the contact area and improve the bonding effect. Furthermore, both the clamping body 321 and the blocking block 311 are made of soft magnetic material, which provides a certain adhesive force between the blocking block 311 and the locking part 32. This not only improves the adsorption effect between the clamping body 321 and the blocking block 311, but also ensures that the use of soft magnetic material has almost no impact when the movable window sash 1 is opened and closed.

[0044] Preferably, the barrier block 311 has clamping strips 312 on both sides for holding the main body of the locking part 32 after it engages with the barrier block 311. Specifically, there are two clamping strips 312 symmetrically arranged, each clamping strip 312 being an inwardly curved body with gradually decreasing thickness. The main body of the barrier part 31 is formed with a corrugated contraction section 313, and the two clamping strips 312 are disposed on the corrugated contraction section 313. The two clamping strips 312 are used to hold the locking part 32 when the corrugated contraction section 313 is impacted and contracted by the barrier block 311 and the locking part 32, thereby improving the sealing effect between the movable window sash 1 and the fixed window frame 2. When the movable window sash 1 is opened, due to the small adsorption force between the blocking block 311 and the clamping body 321, the blocking block 311 will move forward a distance along with the clamping body 321, so as to stretch the corrugated contraction section 313, so that when the movable window sash 1 is closed, the contraction force of the corrugated contraction section 313 can stimulate the clamping strip 312 to clamp.

[0045] Reference Figure 1 Furthermore, a dustproof rubber strip 5 for sealing with the indoor fixed frame 21 is fixed to the bottom inner side of the second stop plate 111 to enhance the sealing effect of the aluminum alloy doors and windows of this application and improve the heat insulation and sound insulation performance.

[0046] Preferably, the first heat insulation strip 13, the second heat insulation strip 23 and the third heat insulation strip 3 are all made of weather-resistant rubber strips.

[0047] The implementation principle of an aluminum alloy door and window structure in this application embodiment is as follows: by setting a first thermal insulation strip 13 on the movable window sash 1 to connect the indoor and outdoor aluminum alloy frame materials, and setting a second thermal insulation strip 23 on the fixed window frame 2 to connect the indoor and outdoor aluminum alloy frame materials, the thermal insulation and sound insulation effects of the aluminum alloy door and window are enhanced in two ways. By setting a first stop plate 221 and a second stop plate 111, the gap between the movable window sash 1 and the fixed window frame 2 can be blocked tightly on the indoor and outdoor sides. Furthermore, a third thermal insulation strip 3 is added between the first stop plate 221 and the second stop plate 111 to further eliminate the gap between the movable window sash 1 and the fixed window frame 2, reduce the convection of indoor and outdoor air, and enhance the sound insulation and thermal insulation effects of the aluminum alloy door and window.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
