Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, and in particular to a self-regulating pressure system within the exterior wall structural layer and a building exterior wall. Background Technology

[0002] The exterior wall structural layer is an important concept in building exterior wall design. It is typically composed of multiple layers and components, mainly including the base layer, insulation layer, waterproofing layer, exterior finish layer, and auxiliary components. The base layer, as the foundation of the exterior wall, is usually made of concrete or masonry, providing structural stability and support. The insulation layer, located above the base layer, is usually made of materials with good thermal insulation properties. The waterproofing layer protects the building from rainwater erosion and penetration. The exterior finish layer is the decorative layer on the building's exterior, providing not only an aesthetically pleasing appearance but also reflecting the building's style and characteristics.

[0003] Maintaining the exterior wall structural layers is crucial for the long-term stability and service life of a building. Due to the influence of indoor and outdoor environments, many exterior wall structural layers inevitably develop various problems after years of use.

[0004] In terms of temperature, temperature changes will cause thermal expansion or contraction in the exterior wall materials, resulting in thermal stress. If the exterior wall structure is not designed properly, this stress may lead to cracks or structural damage.

[0005] Regarding humidity, the difference in humidity between indoors and outdoors causes water vapor to diffuse through the exterior wall structural layer and condense inside, resulting in excessive humidity inside the structural layer. Excessive humidity not only leads to condensation and mold, affecting the health of residents, but also accelerates the aging of the insulation layer, causing a decrease in the bonding strength of the insulation layer, and also accelerates the natural shrinkage process of the exterior wall materials, leading to cracking.

[0006] Furthermore, under the influence of temperature and humidity, if the internal temperature of the exterior wall structure layer is too high, causing the air to expand due to heat, or if the internal moisture content is too high and evaporates to form a large amount of water vapor, it will lead to an increase in the internal pressure of the exterior wall structure layer, creating a pressure difference with the external atmospheric pressure. This not only affects the overall waterproof and thermal insulation performance, but also leads to fatigue and aging of the exterior wall materials, causing them to deform, crack, lose strength, and be prone to emergency damage. Utility Model Content

[0007] The purpose of this utility model is to provide a pressure self-regulating system for the internal structure layer of an exterior wall and a building exterior wall, so as to realize the pressure self-regulation inside the exterior wall structure layer.

The exhaust pump is electrically connected to the control module, and the exhaust pipe is interconnected with the outlet of the exhaust pump. The outlet of the exhaust pipe is open to the external environment of the exterior wall structural layer. The power supply module provides power to the control module, the sensing module, and the exhaust module.

[0010] Furthermore, the sensing module also includes a temperature and humidity sensor, which is communicatively connected to the control module.

[0011] Furthermore, the sensing modules are provided in at least two sets, and are arranged vertically at intervals.

[0012] Furthermore, the exhaust module also includes a two-position three-way solenoid valve, the exhaust pipe includes a first branch pipe and a second branch pipe, the two-position three-way solenoid valve is electrically connected to the control module, and the two-position three-way solenoid valve has a normally closed port, a normally open port and a common port; the normally closed port is connected to the exhaust port of the exhaust pump through the first branch pipe, and the common port is connected to the external environment of the outer wall structure layer through the second branch pipe.

[0013] Furthermore, the two-position three-way solenoid valve is a miniature solenoid valve, and the exhaust pump is a miniature air pump.

[0014] Furthermore, the exhaust module also includes an installation limiting member, which is fixedly disposed on the outside of the exhaust pipe and has an adhesive backing on the side near the exhaust pipe outlet.

[0015] Furthermore, the power supply module includes a battery and a solar photovoltaic panel for charging the battery, with the side of the solar photovoltaic panel that receives sunlight exposed to the exterior wall structure layer.

[0016] Furthermore, it also includes a data display module, which is exposed on the exterior wall structure layer and is communicatively connected to the sensing module.

[0017] A building exterior wall includes a base layer, an exterior finish layer, and a pressure self-regulating system within the aforementioned exterior wall structural layer located between the base layer and the exterior finish layer.

[0018] Furthermore, the exterior trim layer comprises multiple interlocking dry-hanging trim panels, and the exhaust outlet of the exhaust pipe is located at the joint of the dry-hanging trim panels.

[0020] 1. This utility model provides a pressure self-regulating system for the internal structure layer of an exterior wall and a building exterior wall using the system. The sensing module can monitor the internal pressure of the exterior wall structure layer in real time. Based on the detected air pressure value, the exhaust module is opened in time to exhaust air, which can reduce the internal pressure of the exterior wall structure layer, achieve pressure self-regulation, maintain a good pressure environment, and facilitate the maintenance of the exterior wall structure layer.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , 2As shown, this utility model discloses a pressure self-regulating system within an exterior wall structural layer. The system mainly includes a control module 1, a power supply module 2, a sensing module 3, and an exhaust module 4, all built into the exterior wall structural layer. The power supply module 2 supplies power to the control module 1, sensing module 3, and exhaust module 4. The sensing module 3 includes a pressure sensor 31. The exhaust module 4 includes an exhaust pump 41 and an exhaust pipe 42. The pressure sensor 31 is communicatively connected to the control module 1, the exhaust pump 41 is electrically connected to the control module 1, and the exhaust pipe 42 is interconnected with the exhaust pump outlet 412. The exhaust pipe outlet 423 is connected to the external environment of the exterior wall structural layer, i.e., the outdoors.

[0029] The air pressure sensor 31 can monitor the internal air pressure of the exterior wall structural layer in real time and feed the measured air pressure value back to the control module 11. The control module 11 can process the received air pressure information and determine whether the internal pressure of the exterior wall structural layer is too high. The control module 11 can control the exhaust pump 41 to operate when the air pressure exceeds a preset value. After the exhaust pump 41 is turned on, it can draw gas from inside the exterior wall structural layer and discharge it through the exhaust pipe 42, thereby reducing the internal pressure of the exterior wall structural layer and promoting the balance of internal and external pressure of the exterior wall structural layer. Similarly, when the internal pressure of the wall structural layer is too low, the exhaust pump 41 can be turned on to reverse the operation to adjust the internal pressure environment of the wall structural layer.

[0030] In addition, during the exhaust process of the exhaust pump 41, the generated airflow can also carry away and expel moisture from inside the wall structure layer, while uniformly distributing humidity inside the wall structure layer and accelerating the evaporation of moisture, thereby reducing the relative humidity inside the wall structure layer. Therefore, the exhaust module 4, in addition to regulating air pressure, also has a dehumidification function. Correspondingly, the sensing module 3 is also equipped with a temperature and humidity sensor 32, which is communicatively connected to the control module 11. It can monitor the temperature and humidity data inside the wall structure layer in real time and feed it back to the control module 11 so that the control unit can start the exhaust pump 41 for dehumidification as needed.

[0031] At least two sets of the sensing modules 3 are provided for multi-point monitoring. Preferably, the sensing modules 3 are arranged vertically at intervals, and together with the temperature and humidity sensors 32, they can accurately locate the leakage point when leakage occurs from top to bottom, so as to quickly resolve the leakage problem. In this embodiment, the sensing modules 3 are installed at the beams separating the upper and lower floors, and one set is installed every few floors.

[0032] In addition to the exhaust pump 41 and the exhaust pipe 42, the exhaust module 4 also includes a two-position three-way solenoid valve. The exhaust pipe 42 includes a first branch pipe 421 and a second branch pipe 422. The two-position three-way solenoid valve is electrically connected to the control module 1 and has a normally closed port 431, a normally open port 432, and a common port 433. The normally closed port 431 of the two-position three-way valve 43 is connected to the exhaust pump outlet 412 through the first branch pipe 421, and the common port 433 is connected to the external environment of the exterior wall structure layer through the second branch pipe 422.

[0033] Under normal circumstances, the internal and external pressures of the exterior wall structure are maintained through the normally open port 432 and common port 433 of the two-position three-way valve 43, and the second branch pipe 422. When the internal and external pressure difference is large, the normally closed port 431 of the two-position three-way valve 43 can be opened, and the exhaust pump outlet 412 and the second branch pipe 422 can be connected through the first branch pipe 421 to provide conditions for rapid exhaust. When the exhaust pump 41 is turned on, the airflow inside the exterior wall structure can be discharged sequentially through the exhaust pump inlet 411, the exhaust pump outlet 412, the first branch pipe 421, the normally closed port 431, the common port 433, and the second branch pipe 422.

[0034] Preferably, the two-position three-way solenoid valve is a miniature solenoid valve, and the exhaust pump 41 is a miniature air pump for easy installation. Additionally, the exhaust module 4 is equipped with an installation limiting member 44, which is annularly fitted around the outside of the exhaust pipe 42 and fixedly connected to it. The installation limiting member 44 is positioned near the outlet of the exhaust pipe 42, and during installation, it abuts against the back of the trim panel, providing a limiting function. An adhesive backing 441 is provided on the side of the installation limiting member 44 near the exhaust pipe outlet 423, allowing the trim panel to be adhered and providing initial fixation.

[0035] The power supply module 2 in the system includes a battery 21 and a solar photovoltaic panel 22 for charging the battery 21. The side of the solar photovoltaic panel 22 that receives sunlight is exposed to the exterior wall structure, meaning it faces outdoors to continuously receive sunlight to charge the battery 21. In addition, the system also includes a data display module, which is communicatively connected to the sensing module 3. Similar to the solar photovoltaic panel 22, this data display module is exposed to the exterior wall structure and can display air pressure, temperature, and humidity data monitored by the sensing module 3 for easy viewing. In this embodiment, the data display module and the solar photovoltaic panel 22 are combined.

[0036] In summary, the pressure self-regulating system within the exterior wall structure layer has excellent self-regulating functions for air pressure, temperature, and humidity, and can maintain the pressure, temperature, and humidity within the exterior wall structure layer within a suitable range, thus maintaining the various performance characteristics of the exterior wall structure layer at their best.

[0037] Based on this, such as Figure 3 , 4 As shown, this utility model also discloses a building exterior wall, including a base layer 5, an exterior finishing layer 6, and the aforementioned pressure self-regulating system within the exterior wall structural layer. The exterior finishing layer 6 comprises multiple interlocking dry-hanging decorative panels 61, with sealant filling the gaps between the panels to form sealant joints 62. This pressure self-regulating system is located between the base layer 5 and the exterior finishing layer 6, enabling continuous maintenance of the building exterior wall, ensuring it remains in good working order and has a long service life.

[0038] The solar photovoltaic panels 22 and data display module in the system are partially exposed on the exterior finish layer 6 to receive sunlight and display monitoring data. The exhaust pipe outlet 423 in the exhaust module 4 is fixedly installed at the joint of the dry-hanging decorative panel 61, that is, one end of the second branch pipe 422 is fixed at the sealant joint 62. Before fixing, the exhaust pipe outlet 423 can be initially fixed to the joint of the dry-hanging decorative panel 61 using the adhesive 441 on the mounting limiter 44. After initial fixing, it can be fixed to the dry-hanging decorative panel 61 using sealant. Then, the remaining portion of the exhaust pipe 42 located outdoors can be cut off to smooth the exterior finish layer 6. It is evident that the fixing operation of the exhaust pipe outlet 423 is convenient and does not damage the dry-hanging exterior finish panel.
