Description

Technical Field

[0001] The present application relates to the technical field of door and window installation, and in particular to a door and window system installation structure. 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] In order to improve the sealing, insulation and waterproof effects of doors and windows on the interior, it is necessary to fill the cavity between the frame and the wall with a foaming agent when the door and window frame is installed on the wall. The foaming and expansion characteristics of the foaming agent itself ensure the density of the caulking. This dense sealing effect not only enhances the sealing between the frame and the wall, but also effectively prevents moisture penetration, thereby greatly improving the waterproof performance of doors and windows.

[0004] However, in the existing construction process, the filling process of the foaming agent is relatively complicated. Usually, the foaming agent needs to be filled from the indoor side first, and then from the outdoor side. Since the curing time of the foaming agent is about 30 minutes, and the expansion amount can reach about 20%, the foaming agent may overflow from the outdoor side. After the foaming agent is cured, the operator must be required to go outdoors to cut and clean up the overflowed foaming agent. This not only increases the difficulty and time cost of construction, but also brings greater safety risks, especially during the window construction process of high-rise buildings, operators need to work on the exterior wall, and there is a high risk of falling. Summary of the invention

[0005] The purpose of this application is to provide a door and window system installation structure to address the above-mentioned problems, which can reduce the difficulty, time cost and safety hazards during door and window installation, 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 system installation structure, which includes a first foam rod, a filler and a sealant, wherein the first foam rod and the filler are used to fill a cavity between a frame and a wall; two sealants are respectively arranged on the indoor side and the outdoor side of the frame, and the frame and the wall are sealed and connected by the sealant; wherein the first foam rod and the filler are located between the two sealants, the filler is close to the indoor side, the first foam rod is close to the outdoor side, the frame has a first side facing the outdoor side, a first opening is provided between the first side and the wall, the sealant blocks the first opening and is in close contact with the first foam rod.

[0008] In the technical solution of the embodiment of the present application, the first foam rod and the filler are used to fill the cavity between the frame and the wall. After the filler is filled into the cavity between the frame and the wall, the first foam rod is inserted into the cavity between the frame and the wall before the filler is cured to prevent the cured filler from obstructing the first foam rod from entering the cavity between the frame and the wall or squeezing and damaging the first foam rod; two sealants are respectively arranged on the indoor side and the outdoor side of the frame, the frame and the wall are sealed and connected by the sealant, and the sealant is adhered to the wall and the frame at the same time; wherein, the first foam rod and the filler are located between the two sealants, the filler is close to the indoor side, the first foam rod is close to the outdoor side, the frame has a first side facing the outdoor side, and the first side is close to the outdoor side. There is a first opening between the frame and the wall. During the construction process, the operator can fill the filler into the cavity between the frame and the wall on the indoor side, and then go to the outdoor side to insert the first foam rod into the cavity between the frame and the wall from the first opening. The first foam rod is used to replace the existing door and window frame installation technology in which the operator fills the foaming agent and other fillers into the cavity between the frame and the wall from the outdoor side. On the one hand, pushing the first foam rod into the cavity between the frame and the wall can complete the operation of filling the cavity between the frame and the wall from the outdoor side, eliminating the time required to wait for the foaming agent and other fillers to solidify, speeding up the installation efficiency of the frame and the wall, and saving installation time. On the other hand, After a foam rod is inserted into the cavity between the frame and the wall, the sealant on the outdoor side can be installed, which avoids the operator staying outdoors for a long time to wait for the filler to solidify or to go outdoors again for subsequent operations after solidification, saving the time for installing the frames and walls of doors and windows, improving the safety during the installation of the frames and walls of doors and windows, and also eliminating the step of the operator cutting and / or cleaning the part of the filler that expands and solidifies after filling the cavity between the frame and the wall and exceeds the first opening, thereby reducing the difficulty of installing the frames and walls of doors and windows; the sealant blocks the first opening and is in close contact with the first foam rod. On the one hand, the sealant can improve the sealing effect between the frame and the wall, and reduce water, etc. On the one hand, the sealant has good waterproof properties, which can prevent the liquid from contacting the first foam rod or filler, avoid the risk of the first foam rod or filler being corroded by water, and improve the service life of the first foam rod and filler; the first foam rod is connected to the sealant and supports each other, reducing the risk of damage to the sealant due to physical impact such as collision, and the first foam rod can limit the displacement of the sealant by its own position and the viscosity between the sealant and the sealant, avoiding the sealant from repeatedly expanding and contracting until deformation due to thermal expansion and contraction in local areas of the wall and frame (mainly the frame), thereby improving the structural stability and service life of the sealant.

[0009] In some embodiments, the first foam rod is elastic, and the elastic deformation capability of the first foam rod is stronger than the elastic deformation capability of the sealant.

[0010] In the technical solution of the embodiment of the present application, the first foam rod and the sealant are both elastic. When the first foam rod and the sealant are squeezed against each other, the first foam rod and the sealant are subjected to stress of the same magnitude. The elastic deformation ability of the first foam rod is stronger than that of the sealant, and the elastic modulus of the first foam rod is smaller than that of the sealant. The first foam rod is more easily deformed under the action of stress than the sealant, and the elastic force applied to the sealant by the first foam rod after being squeezed and deformed is smaller, thereby reducing the risk of the sealant being pushed by the first foam rod to be deformed or moved and separated from the frame and / or wall, thereby improving the connection stability between the sealant and the frame and the wall.

[0011] In some embodiments, the first foam rod is made of polyethylene foam and the filler is a foaming agent.

[0012] In the technical solution of the embodiment of the present application, the material of the first foam rod is polyethylene foam cotton, which can be deformed during the process of being inserted into the first opening so that it can be more easily inserted into the cavity between the frame and the wall. The filler is a foaming agent, which can expand after being filled into the cavity between the frame and the wall, so that it can easily fill the cavity between the frame and the wall, thereby reducing the risk of gaps between the filler and the frame or wall, and reducing the probability of water vapor or air with a large temperature difference with the indoor temperature entering the room through the gaps between the filler and the frame or wall.

[0013] In some embodiments, the first foam rod is fitted with a filler, and the filler fills a gap between the first foam rod and the wall and / or between the wall.

[0014] In the technical solution of the embodiment of the present application, the first foam rod is fitted with the filler. When the first foam rod is pushed into the cavity between the frame and the wall from the first opening, the first foam rod squeezes the filler, allowing the filler to flow along the gap between the first foam rod and the frame or the wall under the squeezing and pushing of the first foam rod until the filler covers the part of the first foam rod located in the cavity between the frame and the wall. The first foam rod expands to deform itself according to the frame and the wall, and then the filler covering the first foam rod expands to fill the gap between the first foam rod and the frame and the wall, thereby reducing the risk of a gap between the first foam rod and the frame or the wall, and reducing the probability of water vapor or air with a large temperature difference with the indoor temperature entering the room through the gap between the first foam rod and the frame or the wall.

[0015] In some embodiments, a portion of the surface of the first foam rod is a serrated structure, and the first foam rod fits the filler through the serrated surface.

[0016] In the technical solution of the embodiment of the present application, part of the surface of the first foam rod is a serrated structure, and the first foam rod is fitted with the filler through the serrated surface. When the first foam rod enters the cavity between the frame and the wall from the first opening, the filler can enter the gap between the teeth on the surface of the first foam rod and fit tightly therewith, thereby increasing the fitting area between the first foam rod and the filler, thereby enhancing the connection stability between the first foam rod and the filler. In addition, after the filler hardens, it can cooperate with the teeth on the surface of the first foam rod to limit the rotation or displacement of the first foam rod, thereby improving the structural stability of the first foam rod and the filler that fill the cavity between the frame and the wall.

[0017] In some embodiments, a portion of the surface of the first foam rod is a concave-convex structure, and the first foam rod is attached to the sealant through the surface of the concave-convex structure.

[0018] In the technical solution of the embodiment of the present application, part of the surface of the first foam rod is a concave-convex structure. After the first foam rod enters the cavity between the frame and the wall from the first opening, the sealant can fit with the concave-convex structure on the surface of the first foam rod, thereby increasing the contact area between the sealant and the first foam rod, thereby enhancing the connection stability between the first foam rod and the sealant. In addition, the sealant cooperates with the concave-convex structure on the surface of the first foam rod to limit the rotation or displacement of the first foam rod.

[0019] In some embodiments, the frame has a second side facing the inner side of the room, and a plurality of pads for supporting the frame are arranged between the frame and the wall. The plurality of pads are arranged at intervals along the length direction of the frame, and the filler fills the gap between any two adjacent pads among the plurality of pads. One end of the pad is flush with the second side, and the other end of the pad is in contact with the first foam rod.

[0020] In the technical solution of the embodiment of the present application, the frame has a second side facing the inner side of the room, and a plurality of pads for supporting the frame are also arranged between the frame and the wall to prevent the frame from squeezing the filler and the first foam rod. The plurality of pads are arranged at intervals along the length direction of the frame, so that the plurality of pads can stably support the frame and share the weight of the frame, reducing the risk of damage to a single pad due to excessive weight. The filler fills the gap between any two adjacent pads among the plurality of pads, thereby improving the sealing effect of the pad on the cavity between the frame and the wall. One end of the pad is flush with the second side, so that the pad will not exceed the frame, thereby avoiding the risk of external forces affecting the pad, and improving the structural stability of the door and window system installation structure provided by the present application.

[0021] In some embodiments, a second foam rod is also included, and the second foam rod is arranged between the pad and the window sill located on the indoor side. The sealant located on the indoor side connects the second edge and the window sill and is adhered to the second foam rod; the second foam rod abuts against the pad and the window sill, and the second foam rod seals the opening surrounded by any two adjacent pads among the multiple pads and the second edge, and the second foam rod fits with the filler.

[0022] In the technical solution of the embodiment of the present application, the second 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 second foam rod can be squeezed to deform it, thereby avoiding the pad and the window sill from squeezing each other and causing damage to both. The sealant located on the indoor side connects the second side and the window sill and adheres to the second foam rod. The second foam rod supports the sealant and limits the displacement and deformation of the sealant, thereby extending the service life of the sealant. The second foam rod abuts against the pad and the window sill, so that it is not easy for a gap to remain between the second foam rod and the pad and the window sill. The second foam rod blocks the opening formed by any two adjacent pads among the multiple pads and the second side, 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 opening formed by any two adjacent pads among the multiple pads and the second side blocked by the second foam rod. The second foam rod fits the filler, reducing the risk of a gap between the two.

[0023] In some embodiments, the frame is mounted on the wall by screws, the spacer and the first foam rod avoid the screws, and the filler fits the screws.

[0024] In the technical solution of the embodiment of the present application, the pad block and the first foam rod avoid the screws to prevent the screws from passing through the pad block or the first foam rod and destroying the integrity of the pad block and the first foam rod. The filler fits with the screws to prevent gaps around the screws that allow airflow or water vapor to pass through. In addition, the filler can also limit the screws to improve the connection stability between the frame and the wall.

[0025] In some embodiments, a waterproof coating is provided on the surface of the wall body facing the frame body, and the waterproof coating extends from the outdoor side toward the indoor side, and the waterproof coating exceeds the first foam rod.

[0026] In the technical solution of the embodiment of the present application, a waterproof coating is provided on the surface of the wall facing the frame, and the waterproof coating exceeds the first foam rod, thereby reducing the probability of water vapor blocked by the sealant on the outdoor side passing through the wall into the cavity between the frame and the wall.

[0037] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. 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.

[0038] 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.

[0039] 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.

[0040] 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).

[0041] According to some embodiments of the present application, optionally, Figure 1 to Figure 4 As shown, the present application provides a door and window system installation structure, which includes a first foam rod 3, a filler 4, and a sealant 5. The first foam rod 3 and the filler 4 are used to fill the cavity between the frame 1 and the wall 2; two sealants 5 are respectively arranged on the indoor side and the outdoor side of the frame 1, and the frame 1 and the wall 2 are sealed and connected by the sealant 5; wherein the first foam rod 3 and the filler 4 are located between the two sealants 5, the filler 4 is close to the indoor side, and the first foam rod 3 is close to the outdoor side, the frame 1 has a first edge 10 facing the outdoor side, and there is a first opening 12 between the first edge 10 and the wall 2, and the sealant 5 blocks the first opening 12 and is tightly attached to the first foam rod 3.

[0042] The first foam rod 3 is elastic and can be squeezed and deformed in the cavity between the frame 1 and the wall 2 to fit the frame 1 and the wall 2 .

[0043] The size of the first opening 12 is smaller than the diameter of the first foam rod 3. After being squeezed and deformed by the first edge 10 and the wall 2, the first foam rod 3 enters the cavity between the frame 1 and the wall 2 through the first opening 12. After entering the cavity between the frame 1 and the wall 2, the squeezing force on the first foam rod 3 is reduced, and the first foam rod 3 expands rapidly to abut against the inner wall of the frame 1 and the wall 2. On the one hand, when the rod material expands rapidly under the action of its own elasticity, it is easier to deform along the inner wall of the wall 2 and the frame 1 to a shape that completely fits therewith, thereby reducing the risk that the air inside the gap between the first foam rod 3 and the frame 1 and the wall 2 is easily condensed under the influence of temperature to form water droplets and enter the room, or cause the first foam rod 3 and / or filler 4 to be damaged by moisture; on the other hand, after the first foam rod 3 expands rapidly, it can block the first opening 12 and can fit tightly with the sealing sticker that is subsequently pasted to the first opening 12, thereby improving the sealing effect at the first opening 12 and reducing the risk of water vapor and airflow with a large temperature difference from the indoor temperature entering the first opening 12.

[0044] The filler 4 is a material with a certain expansion rate and good thermal insulation effect, so that the filler 4 can expand after entering the cavity between the frame 1 and the wall 2 to fill the cavity between the frame 1 and the wall 2 by itself, thereby reducing the risk of gaps between the filler 4 and the frame 1 and / or the wall 2. The filler 4 mentioned in the present application can be a foaming agent.

[0045] The sealant 5 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 5 mentioned in this application is a solid adhesive strip, which is attached to the joint between the frame 1 and the wall 2 by the operator after the cavity between the frame 1 and the wall 2 is filled. The solid adhesive strip can reduce the time waiting for the sealant 5 to harden during the construction process, speed up the construction efficiency, and use the solid adhesive strip to 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 5 between the frame 1 and the wall 2 at various locations.

[0046] The first foam rod 3 and the filler 4 are used to fill the cavity between the frame 1 and the wall 2. After the filler 4 is filled into the cavity between the frame 1 and the wall 2, the first foam rod 3 is inserted into the cavity between the frame 1 and the wall 2 before the filler 4 is cured, so as to avoid the cured filler 4 from obstructing the first foam rod 3 from entering the cavity between the frame 1 and the wall 2 or squeezing and damaging the first foam rod 3; two strips of sealant 5 are respectively arranged on the indoor side and the outdoor side of the frame 1, and the frame 1 and the wall 2 are sealed and connected by the sealant 5, and the sealant 5 is also adhered to the wall The first foam rod 3 and the filler 4 are located between the two sealants 5, the filler 4 is close to the indoor side, the first foam rod 3 is close to the outdoor side, the frame 1 has a first side 10 facing the outdoor side, and there is a first opening 12 between the first side 10 and the wall 2. During the construction process, the operator can fill the filler 4 into the cavity between the frame 1 and the wall 2 on the indoor side, and then go to the outdoor side to insert the first foam rod 3 into the cavity between the frame 1 and the wall 2 from the first opening 12, and use the first foam rod 3 to replace the existing In some installation techniques of the frame 1 of doors and windows, the operator fills the cavity between the frame 1 and the wall 2 with a foaming agent or other filler 4 from the outside. On the one hand, the first foam rod 3 is pushed into the cavity between the frame 1 and the wall 2 to complete the operation of filling the cavity between the frame 1 and the wall 2 from the outside, eliminating the time required to wait for the foaming agent or other filler 4 to solidify, speeding up the installation efficiency of the frame 1 and the wall 2, and saving installation time. On the other hand, after the first foam rod 3 is inserted into the cavity between the frame 1 and the wall 2, the The sealant 5 on the outdoor side can be installed, which avoids the operator staying on the outdoor side for a long time to wait for the filler 4 to solidify or to go outdoors again for subsequent operations after solidification, saves the time for installing the frame 1 and the wall 2 of the door and window, improves the safety during the installation of the frame 1 and the wall 2 of the door and window, and also saves the operator from cutting and / or cleaning the part of the filler 4 that expands and solidifies after filling the cavity between the frame 1 and the wall 2 and exceeds the first opening 12, thereby reducing the difficulty of installing the frame 1 and the wall 2 of the door and window;

[0047] The sealant 5 blocks the first opening 12 and is in close contact with the first foam rod 3. On the one hand, the sealant 5 can improve the sealing effect between the frame 1 and the wall 2 and reduce the probability of the circulation of liquids such as water or gases with a large temperature difference between the indoor and outdoor areas. On the other hand, the sealant 5 has good waterproofness, which can prevent the liquid from contacting the first foam rod 3 or the filler 4, avoid the risk of the first foam rod 3 or the filler 4 being corroded by water, and improve the service life of the first foam rod 3 and the filler 4; the first foam rod 3 and the sealant 5 are connected and support each other, reducing the risk of damage to the sealant 5 due to physical impacts such as collisions, and the first foam rod 3 can limit the displacement of the sealant by its own position and the viscosity between the sealant and the sealant, avoiding the sealant 5 from repeatedly expanding and contracting until it is deformed due to the thermal expansion and contraction of the local areas of the wall 2 and the frame 1 (mainly the frame 1), thereby improving the structural stability and service life of the sealant 5.

[0048] According to some embodiments of the present application, optionally, the first foam rod 3 is elastic, and the elastic deformation capability of the first foam rod 3 is stronger than the elastic deformation capability of the sealant 5 .

[0049] Elasticity refers to the property of a material being able to deform under the action of an external force and return to its original shape and size after the external force is removed.

[0050] Both the first foam rod 3 and the sealant 5 are elastic. When the first foam rod 3 and the sealant 5 are squeezed against each other, the first foam rod 3 and the sealant 5 are subjected to stress of the same magnitude. The elastic deformation ability of the first foam rod 3 is stronger than that of the sealant 5, and the elastic modulus of the first foam rod 3 is smaller than that of the sealant 5. The first foam rod 3 is more easily deformed under the action of stress than the sealant 5, and the elastic force applied to the sealant 5 by the first foam rod 3 after being squeezed and deformed is smaller, thereby reducing the risk of the sealant 5 being pushed by the first foam rod 3 to be deformed or moved and separated from the frame 1 and / or the wall 2, thereby improving the connection stability between the sealant 5 and the frame 1 and the wall 2.

[0051] According to some embodiments of the present application, optionally, the first foam rod 3 is made of polyethylene foam and the filler 4 is a foaming agent.

[0052] Polyethylene foam, also known as pearl cotton, 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.

[0053] Foaming agent is a substance that can make a substance form holes. It can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Foaming agent is widely used in building materials, plastic products, food industry, pharmaceutical industry and aerospace. In building materials, foaming agent is often used to make thermal insulation materials, heat preservation materials and lightweight concrete.

[0054] The first foam rod 3 is made of polyethylene foam cotton, which can be deformed during the process of being inserted into the first opening 12 so that it can be easily inserted into the cavity between the frame 1 and the wall 2. The filler 4 is a foaming agent, which can expand after being filled into the cavity between the frame 1 and the wall 2, so that it can easily fill the cavity between the frame 1 and the wall 2, thereby reducing the risk of gaps between the filler 4 and the frame 1 or the wall 2, and reducing the probability of water vapor or air with a large temperature difference with the indoor temperature entering the room through the gap between the filler 4 and the frame 1 or the wall 2.

[0055] In some embodiments, the first foam rod 3 may be made of an environmentally friendly material, such as degradable polylactic acid (PLA) or other biodegradable materials, to ensure that the first foam rod 3 can be recycled or naturally degraded after reaching the end of its service life, thereby reducing the impact on the environment.

[0056] According to some embodiments of the present application, optionally, Figure 3 As shown, the first foam rod 3 fits the filler 4 , and the filler 4 fills the gap between the first foam rod 3 and the wall 2 and / or the wall 2 .

[0057] When the filler 4 is filled into the cavity between the frame 1 and the wall 2 from the indoor side, the filler 4 flows from the indoor side toward the outdoor side.

[0058] After the filler 4 is filled into the cavity between the frame 1 and the wall 2 from the indoor side, the opening of the filler 4 entering the gap between the frame 1 and the wall 2 from the indoor side can be blocked, allowing the filler 4 to flow and expand toward the outdoor side, so that the filler 4 can fit more closely with the first foam rod 3.

[0059] The first foam rod 3 is fitted with the filler 4. When the first foam rod 3 is pushed into the cavity between the frame 1 and the wall 2 from the first opening 12, the first foam rod 3 squeezes the filler 4, allowing the filler 4 to flow along the gap between the first foam rod 3 and the frame 1 or the wall 2 under the squeezing and pushing of the first foam rod 3 until the filler 4 covers the part of the first foam rod 3 located in the cavity between the frame 1 and the wall 2. The first foam rod 3 expands to deform itself according to the frame 1 and the wall 2, and then the filler 4 covering the first foam rod 3 expands to fill the gap between the first foam rod 3 and the frame 1 and the wall 2, thereby reducing the risk of a gap between the first foam rod 3 and the frame 1 or the wall 2, and reducing the probability of water vapor or air with a large temperature difference with the indoor temperature entering the room through the gap between the first foam rod 3 and the frame 1 or the wall 2.

[0060] According to some embodiments of the present application, optionally, a portion of the surface of the first foam rod 3 is a serrated structure, and the first foam rod 3 is fitted with the filler 4 through the serrated surface.

[0061] The teeth of the serrated structure on the surface of the first foam rod 3 will be deformed to fit with other teeth after being subjected to force, so that the deformation of the surface of the first foam rod 3 is larger, which is convenient for deformation under the extrusion of the expanded rod material. The reaction force generated by the deformation of the teeth on the surface of the first foam rod 3 is smaller, thereby reducing the magnitude of the internal stress generated by the mutual extrusion of the first foam rod 3 and the filler 4 between the frame 1 and the wall 2.

[0062] Part of the surface of the first foam rod 3 is a serrated structure, and the first foam rod 3 is fitted with the filler 4 through the serrated surface. When the first foam rod 3 enters the cavity between the frame 1 and the wall 2 from the first opening 12, the filler 4 can enter the gap between the teeth on the surface of the first foam rod 3 and fit tightly therewith, thereby increasing the fitting area between the first foam rod 3 and the filler 4, thereby enhancing the connection stability between the first foam rod 3 and the filler 4. In addition, after hardening, the filler 4 can cooperate with the teeth on the surface of the first foam rod 3 to limit the rotation or displacement of the first foam rod 3, thereby improving the structural stability of the first foam rod 3 and the filler 4 that fill the cavity between the frame 1 and the wall 2.

[0063] According to some embodiments of the present application, optionally, a portion of the surface of the first foam rod 3 is a concave-convex structure, and the first foam rod 3 is bonded to the sealant 5 through the surface of the concave-convex structure.

[0064] Part of the surface of the first foam rod 3 is a smooth curved surface with a concave-convex structure, which can evenly disperse the force applied to the contact surface between the first foam rod 3 and the sealant 5 when they are squeezed against each other, thereby reducing the risk of damage to the sealant 5 due to the concentrated force from the first foam rod 3 when the first foam rod 3 and the sealant 5 are attached to each other.

[0065] Part of the surface of the first foam rod 3 is a concave-convex structure. After the first foam rod 3 enters the cavity between the frame 1 and the wall 2 from the first opening 12, the sealant 5 can fit with the concave-convex structure on the surface of the first foam rod 3 to increase the contact area between the sealant 5 and the first foam rod 3, thereby enhancing the connection stability between the first foam rod 3 and the sealant 5. In addition, the sealant 5 cooperates with the concave-convex structure on the surface of the first foam rod 3 to limit the rotation or displacement of the first foam rod 3.

[0066] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4 As shown, the frame 1 has a second side 11 facing the inner side of the room, and a plurality of pads 6 for supporting the frame 1 are arranged between the frame 1 and the wall 2. The plurality of pads 6 are arranged at intervals along the length direction of the frame 1, and the filler 4 fills the gap between any two adjacent pads 6 among the plurality of pads 6. One end of the pad 6 is flush with the second side 11, and the other end of the pad 6 is in contact with the first foam rod 3.

[0067] The second side 11 is crimped onto the top surfaces of the plurality of pads 6. When the filler 4 is injected into the cavity between the frame 1 and the wall 2 from the indoor side, the filler 4 can be filled in turn from the gaps between the plurality of pads 6, so that the filler 4 can fill the gaps between any two adjacent pads 6.

[0068] The process of installing the frame 1 to the wall 2 through the door and window system installation structure provided by the present application is: install the pad 6 to the wall 2, press the frame 1 onto the pad 6, fill the filler 4 into the cavity between the frame 1 and the wall 2 from the indoor side, insert the first foam rod 3 into the cavity between the frame 1 and the wall 2 from the outdoor side, and finally install the sealant 5 (first the outdoor side, then the indoor side, to reserve sufficient curing time for the filler 4).

[0069] The frame 1 has a second side 11 facing the inner side of the room. A plurality of pads 6 for supporting the frame 1 are also arranged between the frame 1 and the wall 2 to prevent the frame 1 from squeezing the filler 4 and the first foam rod 3. The plurality of pads 6 are arranged at intervals along the length direction of the frame 1, so that the plurality of pads 6 can stably support the frame 1 and share the weight of the frame 1, thereby reducing the risk of damage to a single pad 6 due to excessive weight. The filler 4 fills the gap between any two adjacent pads 6 among the plurality of pads 6, thereby improving the sealing effect of the pad 6 on the cavity between the frame 1 and the wall 2. One end of the pad 6 is flush with the second side 11, so that the pad 6 will not exceed the frame 1, thereby avoiding the risk of external forces affecting the pad 6, and improving the structural stability of the door and window system installation structure provided in the present application.

[0070] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4As shown, it also includes a second foam rod 7, which is arranged between the cushion block 6 and the window sill 20 located on the indoor side, and the sealant 5 located on the indoor side connects the second edge 11 and the window sill 20, and is adhered to the second foam rod 7; the second foam rod 7 is in contact with the cushion block 6 and the window sill 20, and the second foam rod 7 blocks the opening surrounded by any two adjacent cushion blocks 6 among the multiple cushion blocks 6 and the second edge 11, and the second foam rod 7 is in contact with the filler 4.

[0071] The material of the second foam rod 7 may be the same as that of the first foam rod 3 , or the material of the second foam rod 7 may be different from that of the first foam rod 3 .

[0072] The top surface of the window sill 20 is flush with the plane of the cushion block 6 .

[0073] The second foam rod 7 is arranged between the cushion block 6 and the window sill 20 located on the indoor side. When the cushion block 6 or the window sill 20 expands due to heat, the second foam rod 7 can be squeezed to deform it, so as to avoid the cushion block 6 and the window sill 20 being squeezed against each other and causing damage to both. The sealant 5 located on the indoor side connects the second edge 11 and the window sill 20 and adheres to the second foam rod 7. The second foam rod 7 supports the sealant 5 and limits the displacement and deformation of the sealant 5, thereby extending the service life of the sealant 5. The second foam rod 7 abuts against the cushion block 6 and the window sill 20, so that the second foam rod 7 and the cushion block 6 and the window sill 20 are unlikely to have a gap, and the second foam rod 7 blocks the opening formed by any two adjacent pads 6 among the multiple pads 6 and the second edge 11, so that the filler 4 filled in the cavity between the frame 1 and the wall 2 can flow and expand from the indoor side to the outdoor side, avoiding the trouble of cutting and cleaning the filler 4 after it expands toward the indoor side and exceeds the opening formed by any two adjacent pads 6 among the multiple pads 6 blocked by the second foam rod 7. The second foam rod 7 fits with the filler 4 to reduce the risk of a gap between the two.

[0074] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 to Figure 5 As shown, the frame 1 is installed on the wall 2 by means of screws 8 , the cushion block 6 and the first foam rod 3 avoid the screws 8 , and the filler 4 fits with the screws 8 .

[0075] The pad 6 and the first foam rod 3 avoid the screw 8 to prevent the screw 8 from passing through the pad 6 or the first foam rod 3 and destroying the integrity of the pad 6 and the first foam rod 3. The filler 4 fits with the screw 8 to prevent gaps around the screw 8 that allow airflow or water vapor to pass through. In addition, the filler 4 can also limit the screw 8 to improve the connection stability between the frame 1 and the wall 2.

[0076] According to some embodiments of the present application, optionally, Figure 1 , Figure 3-4As shown, a waterproof coating 9 is provided on the surface of the wall 2 facing the frame 1 . The waterproof coating 9 extends from the outdoor side toward the indoor side, and the waterproof coating 9 exceeds the first foam rod 3 .

[0077] The waterproof coating 9 may extend beyond the end surface of the cushion block 6 facing the outdoor side.

[0078] The surface of the wall 2 facing the frame 1 is provided with a waterproof coating 9, which exceeds the first foam rod 3, thereby reducing the probability of water vapor intercepted by the sealant 5 located on the outdoor side passing through the wall 2 and entering the cavity between the frame 1 and the wall 2.

[0079] 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.
