Description

Technical Field

[0001] The present application relates to the technical field of doors and windows, and in particular to a sealing structure based on energy-saving framed doors and windows. Background Art

[0002] Doors and windows are an important part of the building's exterior structure and have multiple functions. They not only provide physical protection, but also play a role in regulating the internal environment of the building. Specifically, doors and windows can separate the indoor and outdoor sides of the building to maintain the indoor temperature in a relatively stable range, isolate the wind and moisture from the outdoor side, and maintain a relatively comfortable environment indoors.

[0003] The energy-saving additional frame on doors and windows refers to an auxiliary frame installed between the edge of the doors and windows or the window sashes and the structural layer of the wall (the main load-bearing part of the wall). Its purpose is to improve the thermal insulation, heat insulation, sound insulation and other performances of the doors and windows, while enhancing the overall stability and safety of the doors and windows.

[0004] During the installation of conventional doors and windows, the gap between the door and window frames and the wall usually needs to be sealed with sealing materials to ensure the airtightness and watertightness of the doors and windows. However, due to the temperature difference and humidity changes between indoors and outdoors, as well as the difference in thermal expansion coefficients between the door and window frames and the wall, water vapor will be generated in the wall near the frame. If this water vapor cannot be discharged in time, it may condense inside the wall, causing the wall to become damp and moldy, the installation screws to rust, and the performance of the sealing material to deteriorate. This will not only affect the overall durability of the building, but also increase the cost of maintenance and repair.

[0005] The existing technology mainly uses foaming agents or sealants to fill the gaps between the frames of doors and windows and the walls. However, although these materials can play a certain sealing role, they cannot effectively deal with the problem of water vapor accumulation. Especially in doors and windows with energy-saving auxiliary frames, water vapor may enter the gap between the energy-saving auxiliary frame and the plaster layer of the wall through the plaster layer. In long-term use, water vapor may be retained inside or around the energy-saving auxiliary frame and the sealing material, eventually causing the energy-saving auxiliary frame to rust, deteriorate and deform, and the sealing material to age, crack, or even detach from the substrate. Therefore, how to effectively discharge water vapor and prevent it from being retained inside the door and window structure has become a technical problem that needs to be solved urgently in the existing technology. Summary of the invention

[0006] The purpose of the present application is to provide a sealing structure based on energy-saving framed doors and windows to address the above-mentioned problems, which can discharge water vapor in the door and window structure and improve the above-mentioned problems.

[0007] This application is achieved through the following technical solutions:

[0008] The present application provides a sealing structure based on energy-saving attached frame doors and windows, which includes a frame, a first partition and a second partition.

[0009] In the technical solution of the embodiment of the present application, the frame is installed on the wall through the energy-saving auxiliary frame, and the frame is in contact with the wall through the energy-saving auxiliary frame; the first partition and the second partition are both bonded to the energy-saving auxiliary frame and the wall, one side of the first partition is bonded to the plaster layer, and the other side of the first partition is bonded to the energy-saving auxiliary frame, one side of the second partition is bonded to the plaster layer, and the other side of the second partition is bonded to the energy-saving auxiliary frame, the first partition is located on the outdoor side of the frame, and the second partition is located on the indoor side of the frame, the first partition and the second partition are relatively arranged with the energy-saving auxiliary frame as the center, the first partition has the characteristics of waterproof and breathable, which can block liquid water and allow gaseous water vapor to pass through, and the second partition has It has waterproof and air-proof properties and can block the passage of water and water vapor; wherein, the plaster layer on the wall surface is provided with an opening extending to the structural layer inside the wall, the energy-saving auxiliary frame is located on the inner side of the opening of the plaster layer, the first partition cavity is filled with a first filler, and the energy-saving auxiliary frame and the structural layer are filled with a second filler, the first filler and the second filler can respectively fill the cavity between the energy-saving auxiliary frame and the frame and the cavity surrounded by the energy-saving auxiliary frame, the structural layer, the first partition and the second partition, thereby reducing the air in these cavities and reducing the air flow in these cavities, which causes the indoor temperature to be easily affected by the outdoor temperature or the water vapor to condense into water in these cavities, leaking into the room or corroding the frame, the energy-saving auxiliary frame and / or Or the risk of the first filler and the second filler, improve the air tightness and water tightness between the energy-saving auxiliary frame and the wall, and extend the service life of the frame and the energy-saving auxiliary frame; the first partition and the second partition separate the energy-saving auxiliary frame, the first filler and the second filler from the plaster layer, the internal structural density of the structural layer is higher than the internal structural density of the plaster layer, the structural layer can be regarded as an object that is not easily permeable to water and air, and the plaster layer may contain water or gas. Therefore, the first partition, the second partition, the energy-saving auxiliary frame and the structural layer can form an installation cavity with a certain sealing effect. When the indoor temperature is higher than the outdoor temperature, the internal temperature of the installation cavity is affected by the indoor side and the internal air pressure of the installation cavity increases. The pressure difference is greater than the internal pressure of the plaster layer on the outdoor side. The air pressure difference allows the air inside the installation cavity to pass through the first partition and move to the plaster layer on the outdoor side. During the air flow, the water vapor contained in the installation cavity can be taken away from the installation cavity, thereby reducing the moisture content in the installation cavity, allowing the interior of the installation cavity to remain in a relatively dry state. On the one hand, it prevents the water vapor in the installation cavity from absorbing or releasing heat when the state changes, affecting the internal temperature of the installation cavity, thereby affecting the temperature on the indoor side. On the other hand, it prevents the water vapor in the installation cavity from condensing into water in the installation cavity, causing the energy-saving auxiliary frame and / or the second filler to deteriorate and be damaged, thereby extending the service life of the energy-saving auxiliary frame and the second filler. The door and window sealing structure provided by the present application can discharge the water vapor immersed in the installation cavity by the plaster layer, reduce the risk of water vapor entering the room or corroding the energy-saving auxiliary frame and the second filler, and allow the installation cavity to remain dry for a long time, with good water tightness and air tightness.

[0010] In some embodiments, a portion of the first partition and the second partition bonded to the energy-saving auxiliary frame is located between the first filler and the energy-saving auxiliary frame, and the other portion is located between the plaster layer and the energy-saving auxiliary frame.

[0015] In the technical solution of the embodiment of the present application, a plurality of first pads for supporting the energy-saving auxiliary frame are also arranged on the structural layer. The first pads can allow a cavity to exist between the energy-saving auxiliary frame and the structural layer, thereby avoiding the risk of damage to itself and / or the structural layer due to the difference in thermal expansion coefficients between the energy-saving auxiliary frame and the structural layer, which may cause the energy-saving auxiliary frame to squeeze the structural layer when heated up, thereby preventing the energy-saving auxiliary frame from being damaged and / or the structural layer. The first pad is located on the inner side of the opening of the plaster layer, and the second filler fills the gap between any two adjacent first pads among the plurality of first pads, thereby reducing the risk of gaps around the first pads allowing water vapor to condense; the first partition and the second partition are respectively bonded to the opposite ends of the pad, and the pad presses the first partition and the second partition against the plaster layer, and the first pad can limit the first partition and the second partition and support the first partition and the second partition to fit the plaster layer, thereby improving the structural stability of the installation cavity.

[0016] In some embodiments, a third partition is also included. A first opening facing the outdoor side and a second opening facing the indoor side are provided between the frame and the energy-saving auxiliary frame. The third partition is bonded to the frame and the plaster layer. The third partition has waterproof and air-proof properties. The third partition closes the second opening and fits with the first filler.

[0017] In the technical solution of the embodiment of the present application, the third partition has the characteristics of being waterproof and airtight. The third partition closes the second opening and fits with the first filler. The third partition can prevent water and water vapor from the indoor side from entering the cavity between the frame and the energy-saving auxiliary frame through the second opening, so that the first filler can remain in a relatively dry state, reducing the risk of the first filler being degraded by water.

[0018] In some embodiments, the portion where the third spacer is bonded to the frame is located between the first filler and the frame, and the portion where the third spacer is bonded to the frame is pressed against the frame by the first filler.

[0019] In the technical solution of the embodiment of the present application, the portion where the third partition is bonded to the frame is located between the first filler and the frame, so that the portion where the third partition is bonded to the frame can be blocked by the frame, preventing external factors such as liquid inside the room from affecting the bonding effect between the third partition and the frame, and the portion where the third partition is bonded to the frame is pressed tightly to the frame by the first filler, so that the third partition is tightly fitted to the frame, reducing the risk of gaps between the third partition and the frame.

[0020] In some embodiments, the third partition is bonded to the surface of the plaster layer facing the frame, and the portion of the third partition bonded to the plaster layer extends from the second opening toward the interior of the room; the portion of the second partition bonded to the plaster layer is pressed against the plaster layer by the window sill.

[0022] In some embodiments, a plurality of second pads for supporting the frame body are also provided on the energy-saving auxiliary frame, and the plurality of second pads are arranged at intervals along the length direction of the frame body, and the second pads are located between the first opening and the second opening, and the first filler fills the gap between any two adjacent second pads among the plurality of second pads; one end of the second pad is flush with the second opening and is bonded to the part of the second opening closed by the third partition.

[0023] In the technical solution of the embodiment of the present application, a plurality of second pads for supporting the frame are also provided on the energy-saving auxiliary frame. The second pads can allow a cavity to exist between the frame and the energy-saving auxiliary frame, thereby avoiding the risk of damage to the frame and the energy-saving auxiliary frame due to mutual squeezing when heated due to thermal expansion. The first filler fills the gap between any two adjacent second pads among the plurality of second pads, thereby reducing the risk of gaps around the second pads allowing water vapor to condense; one end of the second pad is flush with the second opening and is bonded to the part of the third partition that closes the second opening. The second pad can limit the third partition and support the third partition to block the second opening 22, thereby improving the structural stability of the third partition.

[0024] In some embodiments, a foam rod is also included. The foam rod is located on the indoor side. The foam rod is located between the second cushion block and the window sill located on the indoor side. The foam rod is pushed by the window sill to press the portion of the third partition located at the second opening onto the second cushion block.

[0025] In the technical solution of the embodiment of the present application, the foam rod is arranged between the second pad and the window sill located on the indoor side. When the second pad or the window sill expands due to heat, the foam rod can be squeezed to deform it, thereby avoiding mutual squeezing of the second pad and the window sill, which may cause damage to both. The foam rod abuts against the second pad and the window sill, so that it is difficult for a gap to remain between the foam rod and the second pad and the window sill. The foam rod fits with the first filler, reducing the risk of a gap between the two.

[0026] In some embodiments, one end of the second spacer bonded to the third separator does not exceed the energy-saving auxiliary frame, and the third separator is bonded to the second separator bonded to the energy-saving auxiliary frame.

[0027] In the technical solution of the embodiment of the present application, one end of the second gasket bonded to the third partition does not exceed the energy-saving auxiliary frame, thereby avoiding the risk that the second gasket pushes the third partition to contact the plaster layer, resulting in the plaster layer being sealed by the third partition and difficult to be self-permeable and breathable. The third partition is bonded to the second partition bonded to the energy-saving auxiliary frame to increase the sealing between the third partition and the second partition, thereby avoiding the water vapor on the indoor side from contacting the first filler or the energy-saving auxiliary frame from between the third partition and the second partition.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0041] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0042] According to some embodiments of the present application, optionally, Figure 1 to Figure 4 As shown, the present application provides a sealing structure based on energy-saving attached frame doors and windows, and the sealing structure based on energy-saving attached frame doors and windows includes a frame 2, a first partition 4 and a second partition 5. The frame 2 is installed on the wall 1 through the energy-saving attached frame 3; the first partition 4 and the second partition 5 are both bonded to the energy-saving attached frame 3 and the wall 1, the first partition 4 is located on the outdoor side of the frame 2, and the second partition 5 is located on the indoor side of the frame 2, the first partition 4 has the characteristics of waterproof and breathable, and the second partition 5 has the characteristics of waterproof and air-proof; wherein, the plaster layer 10 on the surface of the wall 1 is provided with an opening extending to the structural layer 11 inside the wall 1, the energy-saving attached frame 3 is located on the inner side of the opening of the plaster layer 10, the first partition cavity is filled with a first filler 20, and the energy-saving attached frame 3 and the structural layer 11 are filled with a second filler 30, and the first partition 4 and the second partition 5 separate the energy-saving attached frame 3, the first filler 20 and the second filler 30 from the plaster layer 10.

[0043] The top surface of the energy-saving auxiliary frame 3 facing the frame 2 is not lower than the top surface of the plaster layer 10 facing the frame 2, so that the frame 2 and the first filler 20 are staggered with the plaster layer 10, avoiding the contact between the plaster layer 10 and the frame 2 and / or the first filler 20 and then allowing the water vapor in the plaster layer 10 to contact the frame 2 and / or the first filler 20, reducing the risk of the frame 2 / and the first filler 20 being corroded by water vapor.

[0044] The frame 2 mentioned in this article can be composed of a thermal insulation aluminum profile. The frame 2 has a thermal insulation structure. The thermal insulation structure is usually used to describe a building material or component design, where "bridge" refers to the "cold and hot bridge" in materials science, and "break" means interrupting the heat transfer path in some way. In the thermal insulation aluminum material, this design blocks the rapid conduction of heat through the metal by adding non-metallic thermal insulation materials in the middle of the aluminum alloy material, thereby significantly improving the thermal insulation performance of the material.

[0045] When the frame 2 is made of thermal insulation aluminum profiles, the temperatures of the indoor and outdoor sides of the building are separated by the location of the thermal insulation structure of the frame 2, and the location of the partition is the location of the isotherm of the frame 2.

[0046] The first separator 4 can be made of, but is not limited to, the following materials:

[0049] Polyurethane membrane (PU membrane): PU membrane is both waterproof and breathable, suitable for environments that require air circulation. It has high flexibility and is suitable for use in the telescopic parts of buildings, while preventing external rainwater from penetrating.

[0050] Polytetrafluoroethylene (PTFE membrane): This membrane material, due to its unique microporous structure, can provide extremely high air permeability while being waterproof. It is one of the high-performance building materials and is often used in buildings that require high durability and sealing in special environments.

[0051] The second separator 5 can be made of, but is not limited to, the following materials:

[0052] Aluminum foil composite film: Aluminum foil has good air barrier properties and can effectively block water vapor. It also has a certain function of reflecting heat energy. In buildings with high insulation requirements, aluminum foil composite film is a common choice;

[0053] Multilayer polyethylene (PE) film: Compared with single-layer PE film, multilayer PE film can provide better air barrier effect while maintaining flexibility, which is suitable for indoor air barrier to prevent indoor moisture from entering the sealed structure;

[0054] Polyester film (PET film): PET film has good vapor barrier and mechanical strength, can be used in high humidity environment, and provides high heat resistance and wear resistance;

[0055] Polyvinyl chloride film (PVC film): PVC film can well isolate water vapor, and its cost is low, and it is widely used as moisture-proof and moisture-proof gas-barrier film material;

[0056] EVA film (ethylene-vinyl acetate copolymer): EVA has high transparency, flexibility and air barrier effect, and is widely used in occasions that require moisture resistance and high elasticity.

[0057] Both the first filler 20 and the second filler 30 have certain expansion characteristics, and can expand and solidify after being filled between the frame 2 and the energy-saving auxiliary frame 3 and between the energy-saving auxiliary frame 3 and the structural layer 11, thereby reducing the risk of gaps between the frame 2 and the energy-saving auxiliary frame 3 and between the energy-saving auxiliary frame 3 and the structural layer 11; the first filler 20 can be, but is not limited to, expansion cotton, and the second filler 30 can be, but is not limited to, a foaming agent.

[0058] The frame 2 is installed on the wall 1 through the energy-saving auxiliary frame 3, and the frame 2 contacts the wall 1 through the energy-saving auxiliary frame 3; the first partition 4 and the second partition 5 are both bonded to the energy-saving auxiliary frame 3 and the wall 1, one side of the first partition 4 is bonded to the plaster layer 10, and the other side of the first partition 4 is bonded to the energy-saving auxiliary frame 3, one side of the second partition 5 is bonded to the plaster layer 10, and the other side of the second partition 5 is bonded to the energy-saving auxiliary frame 3, the first partition 4 is located on the outdoor side of the frame 2, and the second partition 5 is located on the indoor side of the frame 2, the first partition 4 and the second partition 5 are relatively arranged with the energy-saving auxiliary frame 3 as the center, the first partition 4 has the characteristics of waterproof and breathable, which can block liquid water and allow gaseous water vapor to pass through, and the second partition 5 has waterproof and air-insulating properties. The energy-saving auxiliary frame 3 is located inside the opening of the plaster layer 10, and the first partition cavity is filled with a first filler 20, and the energy-saving auxiliary frame 3 and the structural layer 11 are filled with a second filler 30. The first filler 20 and the second filler 30 can respectively fill the cavity between the energy-saving auxiliary frame 3 and the frame 2 and the cavity surrounded by the energy-saving auxiliary frame 3, the structural layer 11, the first partition 4 and the second partition 5, thereby reducing the air in these cavities and reducing the air flow in these cavities, which makes the indoor temperature easily affected by the outdoor temperature or the water vapor condenses into water in these cavities, leaking into the room or corroding the frame 2, the energy-saving auxiliary frame 3 and the structural layer 11. / or the risk of the first filler 20 and the second filler 30, improve the air tightness and water tightness between the energy-saving auxiliary frame 3 and the wall 1, and extend the service life of the frame 2 and the energy-saving auxiliary frame 3; the first partition 4 and the second partition 5 separate the energy-saving auxiliary frame 3, the first filler 20 and the second filler 30 from the plaster layer 10, the internal structural density of the structural layer 11 is higher than the internal structural density of the plaster layer 10, the structural layer 11 can be regarded as an object that is not easily permeable to water and air, and the plaster layer 10 may contain water or gas. Therefore, the first partition 4, the second partition 5, the energy-saving auxiliary frame 3 and the structural layer 11 can form an installation cavity with a certain sealing effect. When the indoor temperature is higher than the outdoor temperature, the internal temperature of the installation cavity is affected by the indoor side and increases. The internal air pressure of the installation cavity is greater than the internal pressure of the plaster layer 10 on the outdoor side. The air pressure difference allows the air inside the installation cavity to pass through the first partition 4 and move to the plaster layer 10 on the outdoor side. During the air flow, the water vapor contained in the installation cavity can be taken away from the installation cavity, thereby reducing the moisture content in the installation cavity, so that the inside of the installation cavity can be kept in a relatively dry state. On the one hand, it prevents the water vapor in the installation cavity from absorbing or releasing heat when the state changes, affecting the internal temperature of the installation cavity, thereby affecting the temperature on the indoor side. On the other hand, it prevents the water vapor in the installation cavity from condensing into water in the installation cavity, causing deterioration and damage of the energy-saving auxiliary frame 3 and / or the second filler 30, thereby extending the service life of the energy-saving auxiliary frame 3 and the second filler 30.The door and window sealing structure provided in the present application can discharge water vapor that is immersed in the installation cavity by the plaster layer 10, reduce the risk of water vapor entering the room or corroding the energy-saving auxiliary frame 3 and the second filler 30, so that the installation cavity can remain dry for a long time and has good water tightness and air tightness.

[0059] In some embodiments, the frame 2 is made of an insulating aluminum profile, and the projection of the insulating strip of the frame 2 on the second filler 30 is located between the first partition 4 and the second partition 5. The distance between the insulating strip and the first partition 4 is closer than the distance between the insulating strip and the second partition 5, that is, the isotherm with the largest temperature difference between the inside and outside of the frame 2 is close to the first partition 4. When the temperature on the indoor side is higher than that on the outdoor side, when the water vapor in the part of the installation cavity closer to the indoor side moves toward the first partition 4, the water vapor will not be affected by the temperature difference until it moves to the first partition 4 close to the outdoor side, and will pass through the first partition 4 before condensing into water droplets. Since the first partition 4 has the characteristics of waterproof and breathable, the water vapor passing through the first partition from the installation cavity can be easily removed. 4, the condensation of water vapor in the installation cavity will be blocked by the first partition 4, thereby reducing the humidity of the installation cavity. In addition, the arrangement of the heat insulation strip close to the first partition 4 allows most of the installation cavity to be mainly affected by the temperature of the indoor side, and the overall temperature inside the installation cavity is easy to increase, thereby increasing the air pressure inside the installation cavity and guiding the gas inside the installation cavity to move toward the outdoor side, so that the water vapor in the installation cavity can be more easily discharged from the installation cavity; when the temperature inside the indoor side is lower than that outside, the water vapor in the plaster layer 10 on the outdoor side will be affected by the lower temperature cold air toward the indoor side of the heat insulation strip when it approaches the first partition 4, thereby condensing into water and being blocked by the first partition 4, thereby reducing the risk of water vapor on the outdoor side entering the installation cavity.

[0060] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, a portion of the first partition 4 and the second partition 5 bonded to the energy-saving auxiliary frame 3 is located between the first filler 20 and the energy-saving auxiliary frame 3, and the other portion is located between the plaster layer 10 and the energy-saving auxiliary frame 3. The first partition 4 and the second partition 5 are clamped by the energy-saving auxiliary frame 3 and the plaster layer 10.

[0061] The first partition 4 and the second partition 5 can be firstly pasted on the energy-saving auxiliary frame 3, and after the second filler 30 and the energy-saving auxiliary frame 3 are installed, cement or the like is applied on the outer surface of the structural layer 11 to form a plaster layer 10. The plaster layer 10 pushes the first partition 4 and the second partition 5 to deform along the energy-saving auxiliary frame 3, thereby reducing the probability of a gap between the first partition 4 and the second partition 5 and the energy-saving auxiliary frame 3.

[0062] A portion of the first partition 4 and the second partition 5 bonded to the energy-saving auxiliary frame 3 is located between the first filler 20 and the energy-saving auxiliary frame 3, so that the portion of the first partition 4 and the second partition 5 bonded to the plaster can be blocked by the plaster layer 10, thereby preventing external factors such as liquids on the indoor or outdoor side from affecting the bonding effect between the first partition 4 and the second partition 5 and the plaster layer 10; the other portion is located between the plaster layer 10 and the energy-saving auxiliary frame 3, and the first partition 4 and the second partition 5 are clamped by the energy-saving auxiliary frame 3 and the plaster layer 10, so that the first partition 4 and the second partition 5 can fit tightly with the energy-saving auxiliary frame 3, thereby reducing the risk of gaps between the first partition 4 and / or the second partition 5 and the energy-saving auxiliary frame 3.

[0063] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, a portion of the first partition 4 and the second partition 5 bonded to the wall 1 is located between the plaster layer 10 and the structural layer 11, and the first partition 4 and the second partition 5 are clamped by the plaster layer 10 and the structural layer 11, a portion of the first partition 4 located between the plaster layer 10 and the structural layer 11 is extended toward the outdoor side by the second filler 30, and a portion of the second partition 5 located between the plaster layer 10 and the structural layer 11 is extended toward the indoor side by the second filler 30.

[0064] The first partition 4 and the second partition 5 can be first pasted on the structural layer 11, and after the second filler 30 and the energy-saving auxiliary frame 3 are installed, cement or the like is applied to the outer surface of the structural layer 11 to form a plaster layer 10. The plaster layer 10 pushes the first partition 4 and the second partition 5 to deform along the structural layer 11, thereby reducing the probability of a gap between the first partition 4 and the second partition 5 and the structural layer 11.

[0065] The first partition 4 and the second partition 5 are clamped by the plaster layer 10 and the structural layer 11, so that the first partition 4 and the second partition 5 can fit closely with the structural layer 11, reducing the risk of gaps between the first partition 4 and / or the second partition 5 and the structural layer 11. The portion of the first partition 4 located between the plaster layer 10 and the structural layer 11 extends from the second filler 30 toward the outdoor side, and the portion of the second partition 5 located between the plaster layer 10 and the structural layer 11 extends from the second filler 30 toward the indoor side, so that the portions of the first partition 4 and the second partition 5 bonded to the structural layer 11 can remain flat and away from the second filler 30, so that the bonding area between the first partition 4 and the second partition 5 and the structural layer 11 is larger, the connection stability is better, and the gaps in the bonding portions of the first partition 4 and / or the second partition 5 and the structural layer 11 are avoided to affect the drying degree of the second filler 30.

[0066] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 to Figure 5As shown, a plurality of first pads 110 for supporting the energy-saving auxiliary frame 3 are also provided on the structural layer 11, and the plurality of first pads 110 are arranged at intervals along the length direction of the frame body 2, and the first pads 110 are located on the inner side of the opening of the plaster layer 10, and the second filler 30 fills the gap between any two adjacent first pads 110 among the plurality of first pads 110; the first partition 4 and the second partition 5 are respectively bonded to the opposite ends of the pads, and the pads press the first partition 4 and the second partition 5 against the plaster layer 10.

[0067] The first cushion block 110 is used to support the surface of the energy-saving auxiliary frame 3 , and there is a channel between the energy-saving auxiliary frame 3 for the second filler 30 to pass through, so that the second filler 30 can fill the installation cavity more easily.

[0068] A plurality of first pads 110 for supporting the energy-saving auxiliary frame 3 are also provided on the structural layer 11. The first pads 110 can allow a cavity to exist between the energy-saving auxiliary frame 3 and the structural layer 11, thereby avoiding the risk of damage to the energy-saving auxiliary frame 3 and the structural layer 11 due to the difference in thermal expansion coefficients between the energy-saving auxiliary frame 3 and the structural layer 11, which may cause the energy-saving auxiliary frame 3 to squeeze the structural layer 11 when heated, thereby preventing itself and / or the structural layer 11 from being damaged. The first pads 110 are located on the inner side of the opening of the plaster layer 10, and the second filler 30 fills the gap between any two adjacent first pads 110 among the plurality of first pads 110, thereby reducing the risk of gaps around the first pads 110 that allow water vapor condensation; the first partition 4 and the second partition 5 are respectively bonded to the opposite ends of the pads, and the pads press the first partition 4 and the second partition 5 against the plaster layer 10, and the first pads 110 can limit the first partition 4 and the second partition 5 and support the first partition 4 and the second partition 5 to fit with the plaster layer 10, thereby improving the structural stability of the installation cavity.

[0069] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, it also includes a third partition 6. A first opening 21 facing the outdoor side and a second opening 22 facing the indoor side are provided between the frame 2 and the energy-saving auxiliary frame 3. The third partition 6 is bonded to the frame 2 and the plaster layer 10. The third partition 6 has waterproof and air-tight properties. The third partition 6 closes the second opening 22 and fits with the first filler 20.

[0070] The material of the third partition 6 may be the same as that of the second partition 5 ; or, the material of the third partition 6 may be different from that of the second partition 5 .

[0071] The third partition 6 has the characteristics of being waterproof and airtight. The third partition 6 closes the second opening 22 and fits with the first filler 20. The third partition 6 can prevent water and water vapor from the indoor side from entering the cavity between the frame 2 and the energy-saving auxiliary frame 3 through the second opening 22, so that the first filler 20 can remain in a relatively dry state, reducing the risk of the first filler 20 being degraded by water.

[0072] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, the portion where the third separator 6 is bonded to the frame 2 is located between the first filler 20 and the frame 2 , and the portion where the third separator 6 is bonded to the frame 2 is pressed against the frame 2 by the first filler 20 .

[0073] The third partition 6 can be pasted to the frame 2 before the frame 2 is installed, and then pasted to the wall 1 after the first filler 20 fills the cavity between the frame 2 and the energy-saving auxiliary frame 3. The third partition 6 is deformed according to the shape of the solidified first filler 20 before being pasted to the wall 1, reducing the risk of gaps between the third partition 6 and the filler.

[0074] The portion where the third partition 6 is bonded to the frame 2 is located between the first filler 20 and the frame 2, so that the portion where the third partition 6 is bonded to the frame 2 can be shielded by the frame 2, thereby preventing external factors such as liquid inside the room from affecting the bonding effect between the third partition 6 and the frame 2, and the portion where the third partition 6 is bonded to the frame 2 is pressed against the frame 2 by the first filler 20, so that the third partition 6 and the frame 2 fit tightly, reducing the risk of gaps between the third partition 6 and the frame 2.

[0075] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, the third partition 6 is bonded to the surface of the plaster layer 10 facing the frame 2, and the portion of the third partition 6 bonded to the plaster layer 10 extends from the second opening 22 toward the indoor side; the portion of the second partition 5 bonded to the plaster layer 10 is pressed against the plaster layer 10 by the window sill 12.

[0076] The window sill 12 mentioned in the present application refers to a material installed on the window or bay window sill, also known as a window sill. The window sill 12 can prevent rainwater from seeping into the room, thereby preventing the wall from getting moldy or the putty from falling off.

[0077] The portion of the third partition 6 bonded to the plaster layer 10 extends from the second opening 22 toward the indoor side, so that the portion of the third partition 6 bonded to the wall 1 can remain flat and be located outside the cavity between the frame 2 and the energy-saving auxiliary frame 3, so that the bonding area between the third partition 6 and the wall 1 is larger, the connection stability is better, and the gap between the bonding portion of the third partition 6 and the wall 11 is avoided to affect the dryness of the cavity between the frame 2 and the energy-saving auxiliary frame 3; the portion of the third partition 6 bonded to the plaster layer 10 is pressed against the plaster layer 10 by the window sill 12, thereby strengthening the connection strength between the third partition 6 and the plaster layer 10.

[0078] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 to Figure 5 As shown, the energy-saving auxiliary frame 3 is also provided with a plurality of second pads 31 for supporting the frame body 2, and the plurality of second pads 31 are arranged at intervals along the length direction of the frame body 2, and the second pads 31 are located between the first opening 21 and the second opening 22, and the first filler 20 fills the gap between any two adjacent second pads 31 among the plurality of second pads 31; one end of the second pad 31 is flush with the second opening 22 and is bonded to the portion of the third partition 6 that closes the second opening 22.

[0079] The second pad 31 is used to support the surface of the frame 2 and there is a channel between the frame 2 for the first filler 20 to pass through, so that the first filler 20 can easily fill the cavity between the frame 2 and the energy-saving auxiliary frame 3.

[0080] The energy-saving auxiliary frame 3 is also provided with a plurality of second pads 31 for supporting the frame body 2. The second pads 31 can allow a cavity to exist between the frame body 2 and the energy-saving auxiliary frame 3, thereby avoiding the risk of damage to the frame body 2 and the energy-saving auxiliary frame 3 due to mutual squeezing when heated due to thermal expansion. The first filler 20 fills the gap between any two adjacent second pads 31 among the plurality of second pads 31, thereby reducing the risk of gaps around the second pads 31 allowing water vapor to condense; one end of the second pad 31 is flush with the second opening 22 and is bonded to the part of the third partition 6 that closes the second opening 22. The second pad 31 can limit the third partition 6 and support the third partition 6 to block the second opening 2222, thereby improving the structural stability of the third partition 6.

[0081] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, it also includes a foam rod 7, which is located on the indoor side. The foam rod 7 is located between the second cushion block 31 and the window sill 12 located on the indoor side. The foam rod 7 is pushed by the window sill 12 to press the part of the third partition 6 located at the second opening 22 onto the second cushion block 31.

[0082] The foam rod 7 can be but not limited to polyethylene foam, also known as pearl cotton, which is a new type of environmentally friendly packaging material that is light, soft, and has good cushioning and heat preservation properties. It is made of low-density polyethylene resin through a physical foaming process to form countless independent bubble structures, and has good water-proof, moisture-proof, shock-proof, sound-proof, and heat-insulating properties.

[0083] The foam rod 7 is arranged between the second pad 31 and the window sill 12 located on the indoor side. When the second pad 31 or the window sill 12 expands due to heat, the foam rod 7 can be squeezed to deform it, thereby avoiding the second pad 31 and the window sill 12 being squeezed against each other and causing damage to both. The foam rod 7 abuts against the second pad 31 and the window sill 12, so that it is difficult for a gap to remain between the foam rod 7 and the second pad 31 and the window sill 12. The foam rod 7 fits with the first filler 20, reducing the risk of a gap between the two.

[0084] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, one end of the second cushion block 31 bonded to the third partition 6 does not exceed the energy-saving auxiliary frame 3 , and the third partition 6 is bonded to the second partition 5 bonded to the energy-saving auxiliary frame 3 .

[0085] One end of the second gasket 31 bonded to the third partition 6 does not exceed the energy-saving auxiliary frame 3, so as to avoid the second gasket 31 pushing the third partition 6 to contact with the plaster layer 10, resulting in the risk that the plaster layer 10 is closed by the third partition 6 and is difficult to be self-permeable and breathable. The third partition 6 is bonded to the second partition 5 bonded to the energy-saving auxiliary frame 3 to increase the sealing between the third partition 6 and the second partition 5, so as to avoid the water vapor inside the room from contacting the first filler 20 or the energy-saving auxiliary frame 3 from between the third partition 6 and the second partition 5.

[0086] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
