Abstract
Description
Technical Field
[0001] The present application relates to the technical field of doors and windows, and in particular to a sealing structure for 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] During the installation of 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.
[0004] 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. In long-term use, water vapor may be retained inside or around the sealing material, eventually causing the material to age, crack, or even separate 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 in the existing technology. Summary of the invention
[0005] The purpose of the present application is to provide a door and window sealing structure to address the above-mentioned problems, which can discharge water vapor between the doors and windows and the wall, thereby improving the above-mentioned problems.
[0006] This application is achieved through the following technical solutions:
[0007] The present application provides a door and window sealing structure, which includes a frame, a first partition and a second partition. The frame is provided with a thermal insulation strip, and the frame is installed on a wall. A first opening facing the outdoor side and a second opening facing the indoor side are formed between the frame and the wall. The first partition and the second partition are both bonded to the frame and the wall. The first partition closes the first opening, and the second partition closes the second opening. The first partition has waterproof and breathable properties, and the second partition has waterproof and air-tight properties. The first partition, the second partition, the frame and the wall form a partition cavity, and the partition cavity is filled with filler. The projection of the thermal insulation strip on the filler is located between the first partition and the second partition, and the distance between the thermal insulation strip and the first partition is closer than the distance between the thermal insulation strip and the second partition.
[0008] In the technical solution of the embodiment of the present application, the first partition and the second partition are both bonded to the frame and the wall, one end of the first partition is bonded to the frame, the other end of the first partition is bonded to the wall, the middle part of the first partition closes the first opening, one end of the second partition is bonded to the frame, the other end of the second partition is bonded to the wall, the middle part of the second partition closes the second opening, the first partition has the characteristics of being waterproof and breathable, and can block liquid water but allow gaseous water vapor to pass through, and the second partition has the characteristics of being waterproof and air-tight, and can block water and water vapor from passing through; wherein, the first partition, the second partition, the frame and the wall form a partition cavity, and the partition cavity is filled with filler, the filler can fill the partition cavity, reduce the air in the partition cavity, and reduce the risk that the indoor temperature is easily affected by the outdoor temperature due to the air flow in the partition cavity, or the water vapor condenses into water in the partition cavity, leaks into the room or corrodes the frame and / or the filler. , improve the air tightness and water tightness between the frame and the wall, and extend the service life of the frame and the wall; the partition cavity can form a cavity with a certain sealing effect under the action of the first partition and the second partition. When the indoor temperature is higher than the outdoor temperature, the internal temperature of the partition cavity rises due to the influence of the indoor side, and the internal air pressure of the partition cavity is higher than the atmospheric pressure on the outdoor side. The air pressure difference allows the air inside the partition cavity to pass through the first partition and move to the outdoor side. During the air flow, the water vapor contained in the partition cavity can be taken away from the partition cavity, thereby reducing the moisture content in the partition cavity, so that the inside of the partition cavity can be kept in a relatively dry state. On the one hand, it is prevented that the water vapor in the partition cavity absorbs or releases heat when the state changes, affecting the internal temperature of the partition cavity, and then affecting the temperature on the indoor side. On the other hand, it is prevented that the water vapor in the partition cavity condenses into water in the partition cavity, causing aging and cracking of the frame and / or filler, thereby extending the service life of the frame;
[0009] The projection of the heat-insulating strip on the filler is located between the first partition and the second partition. The distance between the heat-insulating strip and the first partition is closer than the distance between the heat-insulating strip and the second partition, that is, the isotherm with the largest temperature difference between the inside and outside of the frame is close to the first partition. When the temperature on the indoor side is higher than that on the outdoor side, when the water vapor in the part of the partition cavity closer to the indoor side moves toward the first partition, the water vapor will not be affected by the temperature difference until it moves to the partition closer to the outdoor side, and will pass through the first partition before condensing into water droplets. Since the first partition has the characteristics of waterproof and breathable, the water vapor passing through the first partition from the partition cavity condenses into water and will be The partition blocks and reduces the humidity of the partition cavity. In addition, the heat insulation strip is arranged close to the first partition so that most of the partition cavity is mainly affected by the temperature of the indoor side. The overall temperature inside the partition cavity is easy to increase, so that the air pressure inside the partition cavity increases, guiding the gas inside the partition cavity to move to the outdoor side, so that the water vapor in the partition cavity is easier to discharge from the partition cavity; when the temperature inside the indoor side is lower than that outside, the water vapor on the outdoor side will be affected by the cold air with lower temperature from the heat insulation strip toward the indoor side when approaching the first partition, so that it condenses into water and is blocked by the first partition, thereby reducing the risk of water vapor on the outdoor side entering the partition cavity. The door and window sealing structure provided by the present application can discharge the water vapor that penetrates into the partition cavity from the wall or other places, reduce the risk of water vapor entering the room or corroding the partition cavity, and allow the partition cavity to remain dry for a long time, with good water tightness and air tightness.
[0010] In some embodiments, the portions where the first and second spacers are bonded to the frame are located between the filler and the frame, and the portions where the first and second spacers are bonded to the frame are pressed against the frame by the filler.
[0011] In the technical solution of the embodiment of the present application, the part where the first partition and the second partition are bonded to the frame is located between the filler and the frame, so that the part where the first partition and the second partition are bonded to the frame can be blocked by the frame, preventing external factors such as liquids on the indoor or outdoor sides from affecting the bonding effect between the first partition and the second partition and the frame, and the part where the first partition and the second partition are bonded to the frame is pressed against the frame by the filler, so that the first partition and the second partition can fit tightly with the frame, reducing the risk of gaps between the first partition and / or the second partition and the frame.
[0012] In some embodiments, the portion of the first partition bonded to the wall extends from the first opening toward the outdoors, and the portion of the second partition bonded to the wall extends from the second opening toward the indoors; the portion of the second partition bonded to the wall is pressed against the wall by the window sill.
[0013] In the technical solution of the embodiment of the present application, the part where the first partition is bonded to the wall extends from the first opening toward the outdoors, and the part where the second partition is bonded to the wall extends from the second opening toward the indoors, so that the parts where the first partition and the second partition are bonded to the wall can remain flat and are located outside the partition cavity, so that the bonding area between the first partition and the second partition and the wall is larger, the connection stability is better, and the gaps in the bonding parts between the first partition and / or the second partition and the wall are avoided to affect the dryness of the wall; the part where the second partition is bonded to the wall is pressed against the wall by the window sill, thereby strengthening the connection strength between the second partition and the wall.
[0014] In some embodiments, a plurality of pads for supporting the frame are further provided on the wall, the plurality of pads are arranged at intervals along the length direction of the frame, the pads are located on the inner side of the partition cavity, and fillers fill the gaps between any two adjacent pads among the plurality of pads; a portion of the first partition that blocks the first opening is bonded to one end of the pad, a portion of the second partition that blocks the second opening is bonded to the other end of the pad, an end of the pad bonded to the first partition is flush with the first opening, and an end of the pad bonded to the second partition is flush with the second opening.
[0015] In the technical solution of the embodiment of the present application, a plurality of pads for supporting the frame are also provided on the wall, and the pads can allow a cavity to exist between the frame and the wall, thereby avoiding the risk of the frame squeezing the wall when heated up due to the difference in thermal expansion coefficients between the frame and the wall, causing damage to itself and / or the wall. The pads are located on the inner side of the partition cavity, and the filler fills the gap between any two adjacent pads among the plurality of pads, thereby reducing the risk of gaps around the pads that allow water vapor to condense; the portion of the first partition that blocks the first opening is bonded to one end of the pad, and the end of the pad bonded to the first partition is flush with the first opening, and the portion of the second partition that blocks the second opening is bonded to the other end of the pad, and the end of the pad bonded to the second partition is flush with the second opening. The pads can limit the first partition and the second partition and support the first partition and the second partition to block the first opening and the second opening, thereby improving the structural stability of the partition cavity.
[0016] In some embodiments, a foam rod is further included, which is located on the indoor side and between the 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 second partition located at the second opening onto the cushion block.
[0017] In the technical solution of the embodiment of the present application, the foam rod is arranged between the pad and the window sill located on the indoor side. When the pad or the window sill is heated and expanded, the foam rod can be squeezed to deform it, thereby avoiding mutual squeezing of the pad and the window sill to cause damage to both; the foam rod abuts against the pad and the window sill, so that it is not easy to leave a gap between the foam rod and the pad and the window sill. Under the push of the window sill, the foam rod and the part of the second partition located at the second opening are pressed against the pad, so that the filler filled in the cavity between the frame and the wall can flow and expand from the indoor side to the outdoor side, thereby avoiding the trouble of cutting and cleaning when the filler expands toward the indoor side and exceeds the foam rod to block the opening formed by any two adjacent pads and the edges among the multiple pads.

[0019] In the technical solution of the embodiment of the present application, the frame has a first side facing the outdoor side, the shedding board is connected to the first side, the shedding board extends from the first side toward the outdoor side, and the shedding board exceeds the wall, so that the shedding board can guide rainwater and other liquids to flow to a position exceeding the wall before falling, so that the part of the wall close to the partition cavity is not easily wetted by the rainwater on the outdoor side, thereby reducing the risk of water vapor infiltrating into the partition cavity; the shedding board avoids the first opening, and the part of the shedding board connected to the first side is not lower than the pad, so that the water vapor in the partition cavity can smoothly leave through the first opening.

The water-shedding plate is sealed to the first side through a sealant, and the sealant covers the nut of the first screw to cover the part of the first screw located outside the frame and the water-shedding plate to prevent water and other liquids from entering the frame along the first screw.
[0022] In some embodiments, a supporting material is further filled between the shedding board and the wall, and the supporting material presses a portion of the first partition located at the first opening onto the cushion block.
[0023] In the technical solution of the embodiment of the present application, supporting material is also filled between the shedding board and the wall. The supporting material makes the gap between the shedding board and the wall solid, thereby reducing the sound of rainwater dripping onto the shedding board, reducing the noise of the shedding board, and improving the comfort of use. The supporting material presses the part of the first partition located at the first opening onto the pad, thereby strengthening the limiting effect of the first partition and reducing the risk of displacement or deformation of the first partition causing a gap between itself and the frame or filler.

[0025] In the technical solution of the embodiment of the present application, the first partition, the second partition and the gasket avoid the second screw to prevent the second screw from destroying the integrity of the first partition, the second partition and the gasket. The filler fits with the second screw to prevent gaps around the second screw that allow airflow or water vapor to pass through. In addition, the filler can also limit the second screw to improve the connection stability between the frame and the wall.
[0026] In some embodiments, a surface of the wall body facing the frame body is further provided with a waterproof coating, the waterproof coating extending from the outdoor side toward the indoor side, passing through the first opening and exceeding the thermal insulation strip.
[0027] In the technical solution of the embodiment of the present application, the waterproof coating extends from the outdoor side toward the indoor side, passes through the first opening and exceeds the thermal insulation strip. The position of the thermal insulation strip is the position of the isotherm with the largest temperature difference of the frame.

[0042] According to some embodiments of the present application, optionally, Figure 1 to Figure 4 As shown, the present application provides a door and window sealing structure, which includes a frame 2, a first partition 3 and a second partition 4. The frame 2 is provided with a thermal insulation strip 20. The frame 2 is installed on the wall 1. A first opening 21 facing the outdoor side and a second opening 22 facing the indoor side are formed between the frame 2 and the wall 1. The first partition 3 and the second partition 4 are both bonded to the frame 2 and the wall 1. The first partition 3 closes the first opening 21, and the second partition 4 closes the second opening 22. The first partition 3 has waterproof and breathable characteristics, and the second partition 4 has waterproof and air-tight characteristics. Among them, the first partition 3, the second partition 4, the frame 2 and the wall 1 form a partition cavity 23, and the partition cavity 23 is filled with filler 5. The projection of the thermal insulation strip 20 on the filler 5 is located between the first partition 3 and the second partition 4, and the distance between the thermal insulation strip 20 and the first partition 3 is closer than the distance between the thermal insulation strip 20 and the second partition 4.
[0043] The frame 2 mentioned in this article is made of thermal insulation broken bridge aluminum profiles. The frame 2 has a broken bridge structure. The broken bridge 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 "broken" means interrupting the heat transfer path in some way. In the broken bridge aluminum material, this design blocks the rapid conduction of heat through the metal by adding non-metallic thermal insulation materials (i.e., the thermal insulation strips 20 mentioned in this application) in the middle of the aluminum alloy material, thereby significantly improving the thermal insulation performance of the material.
[0044] The temperatures of the indoor and outdoor sides of the building are separated by the position where the broken bridge structure of the frame 2 is located, and the position where the partition is located is the position where the isotherm of the frame 2 is located.

[0047] Polypropylene (PP) composite fiber membrane: This material is formed into a waterproof and breathable membrane through multi-layer composite. It is widely used in the waterproof layer of buildings, roofs and walls1. It has strong air permeability and can effectively discharge water vapor to prevent internal moisture retention;
[0048] 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.
[0049] 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.
[0050] The second separator 4 can be made of, but is not limited to, the following materials:
[0051] 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;
[0052] 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;
[0053] 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;
[0054] 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;
[0055] 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.
[0056] The filler 5 has certain expansion characteristics and can expand and solidify after being filled into the partition cavity 23, thereby reducing the risk of voids in the partition cavity 23; the filler 5 can be, but is not limited to, a foaming agent.
[0057] The first partition 3 and the second partition 4 are both bonded to the frame 2 and the wall 1, one end of the first partition 3 is bonded to the frame 2, the other end of the first partition 3 is bonded to the wall 1, the middle part of the first partition 3 closes the first opening 21, one end of the second partition 4 is bonded to the frame 2, the other end of the second partition 4 is bonded to the wall 1, the middle part of the second partition 4 closes the second opening 22, the first partition 3 has the characteristics of being waterproof and breathable, and can block liquid water but allow gaseous water vapor to pass through, and the second partition 4 has the characteristics of being waterproof and air-tight, and can block water and water vapor from passing through; wherein, the first partition 3, the second partition 4, the frame 2 and the wall 1 form a partition cavity 23, and the partition cavity 23 is filled with filler 5, and the filler 5 can fill the partition cavity 23, reduce the air in the partition cavity 23, reduce the risk of air flow in the partition cavity 23 causing the indoor temperature to be easily affected by the outdoor temperature or water vapor condensing into water in the partition cavity 23, leaking into the room or corroding the frame 2 and / or the filler 5, thereby improving the frame The air tightness and water tightness between the frame 2 and the wall 1 extend the service life of the frame 2 and the wall 1; the partition cavity 23 can form a cavity with a certain sealing effect under the action of the first partition 3 and the second partition 4. When the indoor temperature is higher than the outdoor temperature, the internal temperature of the partition cavity 23 rises due to the influence of the indoor side, and the internal air pressure of the partition cavity 23 is higher than the atmospheric pressure on the outdoor side. The air pressure difference allows the air inside the partition cavity 23 to pass through the first partition 3 and move to the outdoor side. During the air flow, the water vapor contained in the partition cavity 23 can be taken away from the partition cavity 23, thereby reducing the moisture content in the partition cavity 23, so that the interior of the partition cavity 23 can be kept in a relatively dry state. On the one hand, it prevents the water vapor in the partition cavity 23 from absorbing or releasing heat when the state changes, affecting the internal temperature of the partition cavity 23, and then affecting the temperature on the indoor side. On the other hand, it prevents the water vapor in the partition cavity 23 from condensing into water in the partition cavity 23, causing aging and cracking of the frame 2 and / or filler 5, thereby extending the service life of the frame 2;
[0058] The projection of the heat-insulating strip 20 on the filler 5 is located between the first partition 3 and the second partition 4. The distance between the heat-insulating strip 20 and the first partition 3 is closer than the distance between the heat-insulating strip 20 and the second partition 4, that is, the isotherm with the largest temperature difference between the inside and outside of the frame 2 is close to the first partition 3. When the temperature inside the room is higher than that outside the room, when the water vapor in the part of the partition cavity 23 closer to the inside of the room moves toward the first partition 3, the water vapor will not be affected by the temperature difference until it moves to the partition closer to the outside of the room, and will pass through the first partition 3 before condensing into water droplets. Since the first partition 3 has the characteristics of waterproof and breathable, the water vapor passing through the first partition 3 from the partition cavity 23 condenses into water and will be The heat insulation strip 20 is arranged near the first partition 3, so that most of the partition cavity 23 is mainly affected by the temperature of the indoor side, and the overall temperature inside the partition cavity 23 is easy to rise, so that the air pressure inside the partition cavity 23 is increased, and the gas inside the partition cavity 23 is guided to move to the outdoor side, so that the water vapor in the partition cavity 23 is easier to be discharged from the partition cavity 23; when the temperature inside the indoor side is lower than that outside, the water vapor outside will be affected by the cold air with lower temperature from the heat insulation strip 20 to the indoor side when it approaches the first partition 3, so that it condenses into water and is blocked by the first partition 3, thereby reducing the risk of water vapor outside entering the partition cavity 23. The door and window sealing structure provided by the present application can discharge the water vapor that penetrates into the partition cavity 23 from the wall 1 or other places, reduce the risk of water vapor entering the room or corroding the partition cavity 23, and keep the partition cavity 23 dry for a long time, with good water tightness and air tightness.
[0059] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, the portion where the first separator 3 and the second separator 4 are bonded to the frame 2 is located between the filler 5 and the frame 2 , and the portion where the first separator 3 and the second separator 4 are bonded to the frame 2 is pressed against the frame 2 by the filler 5 .
[0060] The first partition 3 and the second partition 4 can be pasted to the frame 2 before the frame 2 is installed, and then pasted to the wall 1 after the filler 5 fills the partition cavity 23. The first partition 3 and the second partition 4 are deformed according to the shape of the solidified filler 5 before being pasted to the wall 1, thereby reducing the risk of gaps between the first partition 3 and the second partition 4 and the filler 5.
[0061] The portion where the first partition 3 and the second partition 4 are bonded to the frame 2 is located between the filler 5 and the frame 2, so that the portion where the first partition 3 and the second partition 4 are bonded to the frame 2 can be shielded by the frame 2, thereby preventing external factors such as liquids on the indoor or outdoor sides from affecting the bonding effect between the first partition 3 and the second partition 4 and the frame 2, and the portion where the first partition 3 and the second partition 4 are bonded to the frame 2 is pressed against the frame 2 by the filler 5, so that the first partition 3 and the second partition 4 can fit tightly with the frame 2, thereby reducing the risk of gaps between the first partition 3 and / or the second partition 4 and the frame 2.
[0062] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, the portion of the first partition 3 bonded to the wall 1 extends from the first opening 21 toward the outdoors, and the portion of the second partition 4 bonded to the wall 1 extends from the second opening 22 toward the indoors; the portion of the second partition 4 bonded to the wall 1 is pressed against the wall 1 by the window sill 11.
[0063] The window sill 11 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 11 can prevent rainwater from penetrating into the room, thereby preventing the wall from getting moldy or the putty from falling off.
[0064] The portion where the first partition 3 is bonded to the wall 1 extends from the first opening 21 toward the outdoors, and the portion where the second partition 4 is bonded to the wall 1 extends from the second opening 22 toward the indoors, so that the portions where the first partition 3 and the second partition 4 are bonded to the wall 1 can remain flat and be located outside the partition cavity 23, so that the bonding area between the first partition 3 and the second partition 4 and the wall 1 is larger, the connection stability is better, and the gaps in the bonding portions between the first partition 3 and / or the second partition 4 and the wall 1 that affect the dryness of the wall 1 are avoided; the portion where the second partition 4 is bonded to the wall 1 is pressed against the wall 1 by the window sill 11, thereby strengthening the connection strength between the second partition 4 and the wall 1.
[0065] According to some embodiments of the present application, optionally, Figure 1 , Figure 4-5 As shown, a plurality of pads 6 for supporting the frame 2 are also provided on the wall 1, and the plurality of pads 6 are arranged at intervals along the length direction of the frame 2, and the pads 6 are located on the inner side of the partition cavity 23, and the filler 5 fills the gap between any two adjacent pads 6 among the plurality of pads 6; a portion of the first partition 3 blocking the first opening 21 is bonded to one end of the pad 6, a portion of the second partition 4 blocking the second opening 22 is bonded to the other end of the pad 6, an end of the pad 6 bonded to the first partition 3 is flush with the first opening 21, and an end of the pad 6 bonded to the second partition 4 is flush with the second opening 22.
[0066] The spacer 6 is used to support the surface of the frame 2 and there is a passage between the frame 2 for the filler 5 to pass through, so that the filler 5 can fill the partition cavity 23 more easily.
[0067] A plurality of pads 6 for supporting the frame 2 are also provided on the wall 1. The pads 6 can allow a cavity to exist between the frame 2 and the wall 1, thereby avoiding the risk of the frame 2 squeezing the wall 1 when heated up due to the difference in thermal expansion coefficients between the frame 2 and the wall 1, thereby avoiding the risk of damage to itself and / or the wall 1. The pads 6 are located on the inner side of the partition cavity 23, and the filler 5 fills the gap between any two adjacent pads 6 among the plurality of pads 6, thereby reducing the risk of gaps around the pads 6 that allow water vapor to condense; the portion of the first partition 3 that blocks the first opening 21 is bonded to one end of the pad 6, and the end of the pad 6 bonded to the first partition 3 is flush with the first opening 21; the portion of the second partition 4 that blocks the second opening 22 is bonded to the other end of the pad 6, and the end of the pad 6 bonded to the second partition 4 is flush with the second opening 22; the pad 6 can limit the first partition 3 and the second partition 4 and support the first partition 3 and the second partition 4 to block the first opening 21 and the second opening 22, thereby improving the structural stability of the partition cavity 23.
[0068] 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 cushion block 6 and the window sill 11 located on the indoor side. The foam rod 7 is pushed by the window sill 11 to press the part of the second partition 4 located at the second opening 22 onto the cushion block 6.
[0069] 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.
[0070] The foam rod 7 is arranged between the cushion block 6 and the window sill 11 located on the indoor side. When the cushion block 6 or the window sill 11 expands due to heat, the foam rod 7 can be squeezed to deform it, thereby avoiding that the cushion block 6 and the window sill 11 are squeezed against each other and cause damage to both. The foam rod 7 abuts against the cushion block 6 and the window sill 11, so that it is not easy to leave a gap between the foam rod 7 and the cushion block 6 and the window sill 11. Under the push of the window sill 11, the foam rod 7 and the part of the second partition 4 located at the second opening 22 are pressed against the cushion block 6, so that the filler 5 filled in the cavity between the frame 2 and the wall 1 can flow and expand from the indoor side to the outdoor side, avoiding the trouble of cutting and cleaning when the filler 5 expands toward the indoor side and exceeds the foam rod 7 to block the opening surrounded by any two adjacent cushion blocks 6 and the edges of the multiple cushion blocks 6. The foam rod 7 fits with the filler 5, reducing the risk of a gap between the two.
[0071] According to some embodiments of the present application, optionally, Figure 1 to Figure 4 As shown, it also includes a water-shedding plate 8. The frame 2 has a first edge 24 facing the outdoor side. The water-shedding plate 8 is connected to the first edge 24. The water-shedding plate 8 extends from the first edge 24 toward the outdoor side. The water-shedding plate 8 exceeds the wall 1. The water-shedding plate 8 avoids the first opening 21, and the portion where the water-shedding plate 8 is connected to the first edge 24 is not lower than the pad 6.
[0072] The drip board 8 mentioned in the present application is also called a drip board, which is a protective device installed on the upper or lower part of the door and window, mainly used to prevent rainwater from penetrating into the room through the gaps of the door and window. Its design is usually a water retaining strip with an inclined surface, and the rainwater is directed to the outside, thereby protecting the wall 1 and the indoor environment.
[0073] The frame 2 has a first side 24 facing the outside of the room, and the shedding plate 8 is connected to the first side 24. The shedding plate 8 extends from the first side 24 toward the outside of the room, and the shedding plate 8 exceeds the wall 1, so that the shedding plate 8 can guide rainwater and other liquids to flow to a position exceeding the wall 1 before falling, so that the part of the wall 1 close to the partition chamber 23 is not easily wetted by rainwater on the outside, thereby reducing the risk of water vapor penetrating into the partition chamber 23; the shedding plate 8 avoids the first opening 21, and the part where the shedding plate 8 is connected to the first side 24 is not lower than the pad 6, so that the water vapor in the partition chamber 23 can smoothly leave through the first opening 21.
[0074] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, it also includes a sealant 9. The water-shedding plate 8 is connected to the first edge 24 through a first screw 80. The first screw 80 avoids the first partition 3. The water-shedding plate 8 is sealed and connected to the first edge 24 through the sealant 9. The sealant 9 covers the nut of the first screw 80.
[0075] The sealant 9 is a very critical material in the installation process of building doors and windows. It can provide a good sealing effect, prevent moisture penetration and air leakage, thereby improving the thermal insulation performance and durability of doors and windows. The sealant 9 mentioned in this application is a solid adhesive strip, which is attached to the joint between the water-shedding board 8 and the first side 24 by the operator after the water-shedding board 8 is installed on the first side 24. The solid adhesive strip can reduce the time waiting for the sealant 9 to harden during the construction process and speed up the construction efficiency. The use of solid adhesive strips can also avoid the uneven thickness of the local colloid and the thickness of the colloid in other positions when using liquid glue, resulting in uneven sealing effect of the sealant 9 between the first side 24 and the water-shedding board 8 in various places.
[0076] The water-shedding plate 8 is connected to the first edge 24 through a first screw 80. The first screw 80 avoids the first partition 3 to prevent the first screw 80 from piercing the first partition 3 and causing water to penetrate into the partition chamber 23 along the first screw 80. The water-shedding plate 8 is sealed to the first edge 24 through a sealant 9. The sealant 9 covers the nut of the first screw 80 to cover the part of the first screw 80 located outside the frame 2 and the water-shedding plate 8 to prevent water and other liquids from entering the frame 2 along the first screw 80.
[0077] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, a supporting material 81 is also filled between the water-shedding plate 8 and the wall 1 , and the supporting material 81 presses a portion of the first partition 3 located at the first opening 21 onto the cushion block 6 .
[0078] The material of the supporting material 81 can be the same as that of the filler 5 .
[0079] Support material 81 is also filled between the water-shedding board 8 and the wall 1. The support material 81 makes the gap between the water-shedding board 8 and the wall 1 solid, thereby reducing the sound of rainwater dripping onto the water-shedding board 8, reducing the noise of the water-shedding board 8, and improving the comfort of use. The support material 81 presses part of the first partition 3 located at the first opening 21 onto the cushion block 6, thereby strengthening the limiting effect on the first partition 3 and reducing the risk of displacement or deformation of the first partition 3 causing a gap between itself and the frame 2 or filler 5.
[0080] According to some embodiments of the present application, optionally, Figure 3-4 As shown, the frame 2 is installed on the wall 1 by the second screw 25 , the second screw 25 passes through the partition cavity 23 , the first partition 3 , the second partition 4 and the cushion block 6 avoid the second screw 25 , and the filler 5 fits with the second screw 25 .
[0081] The first partition 3, the second partition 4 and the spacer 6 avoid the second screw 25 to prevent the second screw 25 from destroying the integrity of the first partition 3, the second partition 4 and the spacer 6. The filler 5 fits with the second screw 25 to prevent the formation of gaps around the second screw 25 that allow airflow or water vapor to pass through. In addition, the filler 5 can also limit the second screw 25 to improve the connection stability between the frame 2 and the wall 1.
[0082] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, a waterproof coating 10 is further provided on the surface of the wall 1 facing the frame 2 . The waterproof coating 10 extends from the outdoor side toward the indoor side. The waterproof coating 10 passes through the first opening 21 and exceeds the thermal insulation strip 20 .
[0083] The first partition 3 is bonded to the wall 1 and the portion extending from the partition cavity 23 toward the outdoor side exceeds the waterproof coating 10 to prevent water from accumulating on the waterproof coating 10 and squeezing into the partition cavity 23 through a possible gap between the first partition 3 and the waterproof coating 10 .
[0084] The waterproof coating 10 extends from the outdoor side toward the indoor side, passes through the first opening 21 and exceeds the thermal insulation strip 20. The thermal insulation strip 20 is located at the position of the isotherm where the temperature difference of the frame 2 is the largest. Therefore, the water vapor in the wall 1 facing the thermal insulation strip 20 is easily condensed into water. The waterproof coating 10 can prevent the water in the wall 1 facing the thermal insulation strip 20 from penetrating into the partition cavity 23, thereby ensuring the dryness of the partition cavity 23.
