[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figure 1 As shown, the composite wall structure 100 with built-in heat insulation layer of this application includes a base layer 1, a waterproof and breathable membrane 2, a heat insulation layer 3, and a flow channel 4.

[0028] The substrate layer 1 is the main supporting component of the composite wall structure 100, and it is typically made of high-strength materials such as concrete, aerated concrete, or high-density bricks. This layer not only provides mechanical strength to the entire wall structure but also serves to secure other functional layers. The substrate layer 1 constitutes a large portion of the thickness of the composite wall, and its excellent mechanical properties ensure the overall stability and load-bearing capacity of the wall.

[0029] A waterproof and breathable membrane 2 is disposed on one side of the substrate layer 1 to prevent external moisture from entering while allowing internal moisture to escape. The waterproof and breathable membrane 2 is made of a microporous material, such as polytetrafluoroethylene (PTFE) film, which has excellent waterproof performance and breathability.

[0030] The insulation layer 3 is located between the waterproof and breathable membrane 2 and the substrate layer 1. Its function is to form a thermal barrier between the internal and external environments, reducing heat transfer and minimizing the impact of temperature differences between the inside and outside on the wall. The insulation layer 3 can be made of materials with good thermal insulation properties, such as polystyrene foam board, rock wool board, or glass wool board. During installation, the insulation layer 3 must be firmly fixed between the waterproof and breathable membrane 2 and the substrate layer 1. This can be achieved through adhesives or mechanical fasteners, ensuring seamless contact between the insulation layer 3 and adjacent layers to improve the overall thermal insulation effect.

[0031] The drainage channel 4 is configured on the outer surface of the waterproof and breathable membrane 2, primarily to guide any condensate that may form out of the composite wall structure 100, preventing moisture accumulation inside the wall. The drainage channel 4 is typically designed as a groove or channel, installed along the height of the wall, and maintains unobstructed connection to the outside to ensure smooth drainage of condensate. The drainage channel 4 can be implemented by embedding it into the groove of the waterproof and breathable membrane 2 or by manufacturing and attaching a separate drainage strip to the surface of the membrane 2. The design of these drainage channels 4 must consider the water flow path to ensure timely drainage when condensate forms, effectively preventing internal dampness and mold growth.

[0032] In one embodiment, the composite wall structure 100 with built-in insulation layer of this application includes a base layer 1 and a built-in insulation layer 3. The base layer 1 is made of high-density concrete, which not only possesses excellent mechanical properties and durability but also effectively blocks the influence of the external environment on the internal environment. To improve the structure's moisture-proof and condensation-resistant performance, multiple ventilation holes 5 are provided inside the base layer 1. These ventilation holes 5 extend throughout the entire base layer 1, allowing free airflow between indoors and outdoors. Through this design, when there is a large temperature difference between indoors and outdoors, indoor and outdoor air can naturally convection through these ventilation holes 5, effectively mitigating the accumulation of condensation. Furthermore, the arrangement of these ventilation holes 5 can be further optimized; for example, the ventilation holes 5 can also be arranged along the wall to ensure a reasonable airflow path, improving the overall thermal performance and comfort of the structure.

[0033] For example, prefabricated hollow tubes or rods can be inserted during the molding process of the base layer 1, and then removed after the concrete has solidified to form the required ventilation holes 5. Furthermore, the uniform layout of the ventilation holes 5 can be ensured by precisely controlling the position and spacing of the formwork to optimize airflow. For instance, in large wall structures, ventilation holes 5 can be set segment by segment using a staged casting method to ensure the structural stability and functionality of the entire wall.

[0034] In one embodiment, in the composite wall structure 100 with built-in insulation layer of this application, the waterproof and breathable membrane 2 comprises a multi-layered microporous structure, each layer being made of a hydrophobic material, thereby ensuring that moisture can be discharged outward through the membrane layer while preventing external moisture intrusion. A uniform anti-condensation coating 6 is applied to the inner surface; this coating possesses unique moisture absorption and release functions, capable of absorbing excess moisture when cold air enters the wall and gradually releasing it under suitable conditions. This design not only effectively prevents the accumulation of internal moisture but also ensures the overall breathability and stability of the wall structure.

[0035] The application of the anti-condensation coating 6 further enhances the performance of the waterproof and breathable membrane 2. This coating, made of hydrophobic polymer material, undergoes special treatment to form a nanoscale protective film on its surface. This film traps and stores moisture entering the wall, then gradually releases the stored moisture when temperature and humidity conditions permit. This process not only prevents condensation but also maintains a dry and stable internal environment within the wall. The coating adheres tightly to the inner surface of the waterproof and breathable membrane 2, ensuring the integrity and functionality of the entire wall structure.

[0036] For example, the anti-condensation coating 6 can be uniformly applied to the inner surface of the waterproof and breathable membrane 2 by spraying or coating. The multi-layered microporous structure of the waterproof and breathable membrane 2 can be prepared using a physical lamination process to ensure good bonding and breathability between each layer of material. Specifically, a suitable hydrophobic material is first selected, and a microporous structure is formed by hot pressing, extrusion, or other suitable methods. Then, an anti-condensation coating 6 is sprayed onto its inner surface.

[0037] In one embodiment, such as Figure 2 As shown, the insulation layer 3 in the composite wall structure 100 with built-in insulation layer of this application is composed of several parallel-arranged insulation boards. These insulation boards maintain a certain distance from each other, and foamed plastic 7 is filled between adjacent insulation boards to form a honeycomb structure. This design can significantly improve the insulation performance of the wall, reduce the formation and accumulation of condensate, and further enhance the thermal insulation and waterproofing capabilities of the structure. Specifically, a fixed spacing is maintained between each insulation board by a fixing device to ensure that the foamed plastic 7 can be uniformly filled. Through this structural design, not only is the thermal insulation effect of the wall enhanced, but the occurrence of cold bridging is also effectively prevented.

[0038] For example, the insulation panels can be made of high-performance lightweight materials, such as polystyrene or rock wool, which inherently possess excellent thermal insulation properties. The foamed plastic 7 between the insulation panels can be made of polyurethane foam or expanded polystyrene, which not only provides excellent thermal insulation but also effectively prevents water and moisture damage. During actual construction, the insulation panels can be positioned using a pre-fabricated frame, and then the foamed plastic 7 is injected between the panels, finally curing to form a stable honeycomb structure. In this way, the insulation layer 3 of the entire composite wall not only provides excellent thermal insulation but also boasts outstanding waterproof and moisture-proof performance.

[0039] Return to reference Figure 1 To further reduce condensation formation, in one embodiment, the composite wall structure 100 with built-in insulation layer of this application has several heating cables 8 pre-embedded inside the base layer 1. These cables are connected to a constant temperature control system, which can automatically adjust the temperature inside the base layer 1 to ensure that the inside and outside of the waterproof and breathable membrane 2 always maintain an appropriate temperature difference, thereby effectively preventing the formation and accumulation of condensation. This design not only improves the moisture-proof performance of the composite wall but also ensures the stability and comfort of the wall under different environmental conditions. The base layer 1 is typically made of high-strength concrete or similar materials, which can provide necessary structural support while protecting the insulation layer 3.

[0040] In another embodiment, heating cables 8 are evenly distributed inside the substrate layer 1 and fixed through pre-set channels or an embedded arrangement. Each heating cable 8 is wrapped with an insulating sleeve to prevent short circuits or thermal damage, while ensuring uniform heating. The constant temperature control system includes temperature sensors and controllers, installed at different locations on the wall, capable of monitoring the internal and external temperatures in real time and adjusting the power output of the heating cables 8 to ensure the temperature remains within the set range. In this way, the temperature difference between the inside and outside of the waterproof and breathable membrane 2 is always at an optimal level, thereby preventing the generation of condensation.

[0041] Specifically, to achieve the above functions, the heating cable 8 is installed inside the substrate layer 1 through pre-designed wiring channels. The length and spacing of each wiring channel are precisely controlled to ensure uniform heat distribution. Temperature sensors are installed on the inner and outer surfaces of the substrate layer 1, respectively, and transmit the detected temperature data to the central controller. The controller adjusts the working state of the heating cable 8 according to the preset temperature difference threshold, thereby achieving the purpose of constant temperature control.

[0042] In one embodiment, the waterproof and breathable membrane 2 of the composite wall structure 100 with built-in insulation layer of this application is fixed to the insulation layer 3 by means of a groove. This groove method not only ensures a stable connection between the two, but also facilitates the assembly of other structures. The groove design typically involves pre-fabricating a groove of a certain depth on one side of the insulation layer 3 so that the waterproof and breathable membrane 2 can fit tightly and be embedded in the groove at its outer edge. To further enhance the sealing performance at the joint and avoid tension problems caused by foundation settlement or other external factors during long-term use of the building, a flexible sealing strip 9 is also filled at the joint. The flexible sealing strip 9 has excellent elasticity and sealing performance, and can adapt to structural deformation to a certain extent, thereby effectively preventing the infiltration and accumulation of condensate.

[0043] Specifically, a groove suitable for the size and shape of the waterproof and breathable membrane 2 can be first made on the insulation layer 3. Then, one end of the waterproof and breathable membrane 2 is embedded into the groove, ensuring that the embedded part is tightly attached to the groove wall. Next, an appropriate amount of flexible sealing strip 9 is applied to the joint to fill the opening of the groove, making it completely sealed. For example, the flexible sealing strip 9 can be applied evenly to the joint of the groove by hand or using a special tool to ensure that the sealing strip covers the joint evenly and without omissions. In this way, even when the building undergoes minor deformation, the flexible sealing strip 9 can maintain the sealing of the joint, prevent moisture intrusion and condensation accumulation, and ensure the waterproof and moisture-proof performance of the entire composite wall structure 100.

[0044] In one embodiment, in the composite wall structure 100 with built-in insulation layer of this application, the insulation layer 3 is embedded with a special water-absorbing material 10, which can regulate humidity under different conditions. Specifically, the water-absorbing material can absorb and store excess moisture when the relative humidity is high, and slowly release the stored moisture when the relative humidity is low, thereby maintaining a constant indoor humidity. This design not only effectively prevents condensation within the wall but also improves living comfort and energy efficiency.

[0045] In one specific implementation, the absorbent material is typically a porous polymer or natural mineral material, possessing a large surface area and excellent moisture absorption properties. The absorbent material can be evenly distributed within the insulation layer 3, ensuring uniform moisture absorption and release throughout the entire wall structure. To ensure good moisture absorption, the absorbent material can be physically filled and fixed within the insulation layer 3, or it can be mixed with the insulation layer 3 material and integrally molded, thus better integrating into the overall structure of the composite wall. For example, an appropriate amount of absorbent material powder can be added during the manufacturing process of the insulation layer 3, followed by high-pressure molding, to ensure the absorbent material is evenly distributed within the insulation layer 3. This method is not only simple but also ensures good bonding between the absorbent material and the insulation material, further enhancing the stability and functionality of the overall structure.

[0046] In one embodiment, such as Figure 3 As shown, the guide channel 4 of the composite wall structure 100 with built-in insulation layer of this application is designed in an inverted V shape to effectively manage and discharge condensate. This guide channel 4 is positioned along the height of the wall, forming a top-down guiding path to ensure that any condensate that forms can quickly flow to the bottom of the wall and be safely discharged through the external drainage pipe 11, thereby preventing moisture from accumulating inside the wall for extended periods and causing corrosion or other damage. The inverted V-shaped design not only optimizes the water flow guidance efficiency but also enhances the stability of the structure, avoiding wall deformation and material deterioration caused by moisture accumulation. Furthermore, the connection between the guide channel 4 and the external drainage pipe 11 is sealed, further ensuring the reliability and service life of the system.

[0047] In one specific implementation, an inverted V-shaped drainage channel 4 made of waterproof material can be provided on the outside of the waterproof and breathable membrane. Simultaneously, a connection interface is provided at the bottom of the wall to effectively connect the drainage channel 4 to the external drainage pipe 11. Specifically, metal or plastic connectors can be used, along with waterproof tape or sealant, to ensure that no leakage occurs at the interface, thereby guaranteeing the efficient operation and long-term stability of the entire drainage system.

[0048] In one embodiment, the composite wall structure 100 with built-in insulation layer of this application has an additional inclined moisture-proof board 12 on the outside of its waterproof and breathable membrane 2, effectively preventing rainwater or water from accumulating on the upper surface of the composite wall. This design not only reduces structural damage caused by moisture retention but also significantly reduces the probability of condensation and accumulation of steam inside the wall due to temperature changes. The moisture-proof board 12 design gives the composite wall better moisture-proof performance, thereby extending the overall service life of the wall and improving the safety and comfort of the building.

[0049] In practical applications, the moisture-proof board 12 is typically made of high-strength, weather-resistant materials, such as metal or composite materials, to ensure it maintains good moisture-proof performance over a long period under various environmental conditions. Specifically, the moisture-proof board 12 is installed at an angle on the outside, with one end fixed to the edge of the waterproof and breathable membrane 2, and the other end slightly tilted outward to guide rainwater to flow away smoothly. The connection between the moisture-proof board 12 and the waterproof and breathable membrane 2 can be achieved through bolts, fasteners, or other suitable connection methods, ensuring a firm and airtight connection to maximize its moisture-proof function. For example, a sealing strip can be added to the lower edge of the moisture-proof board 12 to further enhance its waterproof performance.

[0050] In one embodiment, the composite wall structure 100 with built-in insulation layer of this application embeds a specially designed conductive mesh within the drainage channel 4 and is linked to a dehumidifier. The purpose of this design is that when the humidity sensor detects that the humidity in the air exceeds a preset threshold, the conductive mesh can generate heat by being energized, thereby accelerating the rapid evaporation of condensed moisture within the wall and effectively preventing the accumulation of moisture inside the wall, thus protecting the wall from moisture damage. This design not only improves the waterproof performance of the wall but also extends its service life and enhances the comfort of the indoor environment.

[0051] Specifically, the conductive wire mesh is carefully installed inside the airflow channel 4, ensuring its even distribution at specific locations within the channel 4, thereby achieving effective heat transfer. Furthermore, the linkage between the conductive wire mesh and the dehumidifier is achieved through a circuit control system. This system activates immediately upon receiving an alarm from the humidity sensor, transferring current to the conductive wire mesh to heat it. The humidity sensor is installed on the side closest to the interior of the wall to accurately monitor changes in indoor humidity, ensuring timely activation of dehumidification and heating functions when needed.

[0052] In one embodiment, the composite wall structure 100 with built-in insulation layer of this application has a layer of nano self-cleaning paint 13 sprayed onto the exterior of its base layer 1. This nano self-cleaning paint 13 not only effectively cleans dust and other dirt adhering to the surface, but also effectively blocks the penetration of ultraviolet rays, thereby reducing material aging problems caused by ultraviolet radiation. Furthermore, this coating also has the ability to reduce condensation caused by environmental changes, especially in environments with high humidity or large temperature differences. The coating can reduce condensation by reducing heat exchange between the base layer 1 and the external environment. This design helps improve the durability and aesthetics of the wall structure while reducing maintenance costs.

[0053] In one embodiment, the composite wall structure 100 with a built-in insulation layer of this application has the following features: a breathable insulation cotton board 14 is added around the insulation layer 3. This breathable insulation cotton board 14 has good thermal insulation performance and breathability, ensuring that internal heat is not excessively lost while allowing internal moisture to diffuse smoothly, thereby effectively reducing moisture condensation caused by uneven internal and external air humidity. This design not only improves the overall thermal insulation effect of the wall but also solves common problems caused by moisture accumulation in wall structures, such as mold and corrosion.

[0054] The breathable insulation board 14 added around the insulation layer 3 of the composite wall structure 100 not only improves the overall energy efficiency of the building but also enhances living comfort. The thickness and density of the breathable insulation board 14 can be adjusted according to specific climatic conditions and building requirements to achieve optimal insulation and breathability. Through reasonable material selection and construction techniques, this design can significantly improve the durability and functional stability of the wall.

[0055] In practical applications, the breathable insulation board 14 is typically installed between the insulation layer 3 and the external decorative layer. This board is made of porous fiber material, possessing high air permeability and low thermal conductivity. During installation, it is crucial to ensure the breathable insulation board 14 is tightly fitted to the insulation layer 3 without gaps to maximize its insulation effect. For example, a specialized adhesive can be used to fix the board to the insulation layer 3, while sealing strips are used at the edges of the board to further enhance its sealing performance. In this way, the wall achieves effective insulation and breathability while preventing moisture accumulation inside the wall, thereby extending the wall's service life.

[0056] In practical operation, when the external environment changes, the substrate layer 1, as the main load-bearing part of the entire wall structure, provides stable physical support, ensuring the structural safety of the building. The waterproof and breathable membrane 2 covers one side of the substrate layer 1. On the one hand, it effectively blocks external moisture from entering the wall, preventing dampness; on the other hand, it has a breathable function, allowing internal moisture to escape through its surface, thus maintaining a dry environment inside the wall. The thermal insulation layer 3 is located between the waterproof and breathable membrane 2 and the substrate layer 1. Its excellent thermal insulation performance blocks heat transfer between the inside and outside, reducing energy loss due to indoor and outdoor temperature differences and improving the building's energy efficiency. Furthermore, the drainage channel 4 is designed on the outer surface. Through a reasonable tilt angle and structure, it effectively guides external condensate or other moisture that may form on the outer surface of the waterproof and breathable membrane 2, allowing it to drain directly into the wall through its openings. This avoids the risk of condensate accumulation inside the wall, further enhancing the wall's moisture resistance and durability. Overall, these four key components work together to meet the multiple functional requirements of the composite wall structure 100, providing a more comfortable and energy-efficient environment for the building.

[0057] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
