Description

Technical Field

[0001] This application relates to the technical field of building exterior wall insulation and decoration, and in particular to the waterproof structure of building insulation and decoration structural panels. Background Technology

[0002] With the continuous development of modern building technology and people's increasing demands for building comfort and energy efficiency, building insulation and decorative structural panels are being used more and more widely in various building projects. They integrate multiple functions such as insulation and decoration, which not only help improve the thermal comfort of the building interior, reduce energy consumption, and meet building energy conservation standards, but also beautify the building appearance and save construction time and costs. Therefore, they have received high attention and favor from the construction industry.

[0003] However, in practical applications, many traditional thermal insulation and decorative structural panels have significant shortcomings in terms of water prevention. On the one hand, buildings are constantly exposed to external moisture such as rainwater and water vapor. If the water prevention performance of the thermal insulation and decorative structural panels is poor, moisture can easily seep into the structure, causing the insulation layer to become damp, thereby reducing its insulation effect, increasing the building's energy consumption, and increasing the thermal conductivity of the insulation material after it becomes damp, making it easier for heat to dissipate and affecting the overall insulation performance of the building. On the other hand, water infiltration may also cause a series of durability problems, such as corrosion and mildew of the insulation layer, as well as adhesion failure between the insulation layer and other structural layers due to moisture, which seriously affect the service life of the structural panels and may even pose a potential threat to the structural safety of the building.

[0004] In view of the above problems, the construction industry urgently needs a thermal insulation and decorative structural panel with high-efficiency anti-seepage performance; it can effectively block the entry of external moisture, and at the same time properly handle the possible condensation of water vapor inside, ensuring that the insulation layer and the entire structural panel maintain good performance during long-term use, improving the quality and durability of buildings, and meeting the comprehensive requirements of modern buildings for thermal insulation, decoration and waterproofing. Utility Model Content

[0005] In order to effectively prevent the ingress of external moisture and properly handle possible internal condensation, ensuring that the insulation layer and the entire structural panel maintain good performance during long-term use, improving the quality and durability of the building, and meeting the comprehensive requirements of modern buildings for insulation, decoration, and waterproofing, this application provides a waterproof structure for building insulation and decorative structural panels.

[0006] The waterproof structure of the building insulation and decorative structural panel provided in this application adopts the following technical solution: it includes an outer shell, and an insulation board body is provided on the inner side of the outer shell. The insulation board body is arranged from the outside to the inside as an outer protective layer, a first waterproof layer, an insulation layer, a second waterproof layer, and an interface treatment layer; a high-strength crack-resistant mortar board is provided on the front side of the insulation board body, and a flow guiding component is provided between the high-strength crack-resistant mortar board and the outer shell.

[0007] Optionally, the flow guiding assembly includes a fixing plate, which is fixedly connected to the housing by screws. A flow guiding plate is installed on the front side of the fixing plate, and the flow guiding plate is inclined and disposed on the outside of the high-strength crack-resistant mortar board.

[0008] Optionally, the outer protective layer is a ceramic sheet with a thickness of 3-5 mm.

[0009] Optionally, the first waterproof layer is configured as a polymer self-adhesive waterproof membrane, the thickness of which is 1.5mm.

[0010] Optionally, the insulation layer is a rock wool board, with grooves on both sides of the rock wool board, and a limiting plate is provided in the groove, the limiting plate being installed on the inner wall of the outer shell.

[0011] Optionally, the second waterproof layer is configured as a breathable waterproof membrane, the breathable waterproof membrane being made of thermoplastic polyurethane, and the thickness of the breathable waterproof membrane being 0.3-1.2 mm.

[0012] Optionally, the interface treatment layer consists of an interface agent and an alkali-resistant mesh fabric. The interface agent is a polymer-modified mortar with a thickness of 1-2 mm, and the alkali-resistant mesh fabric is a standard fiberglass mesh with a total thickness of 0.3-0.5 mm.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model uses an insulation board body consisting of an outer protective layer, a first waterproof layer, a thermal insulation layer, a second waterproof layer, and an interface treatment layer. Each layer is made of specific materials, such as ceramic thin plates for the outer protective layer, high-polymer self-adhesive waterproof membrane for the first waterproof layer, and breathable waterproof membrane for the second waterproof layer. This effectively blocks the erosion of external rainwater and moisture, prevents moisture from seeping into the structure and causing the insulation layer to become damp, thereby maintaining the good thermal insulation effect of the insulation layer, reducing building energy consumption, ensuring the overall thermal insulation performance of the building, and meeting building energy conservation standards.

[0015] 2. This utility model is equipped with a flow guiding component. The flow guiding plate is inclined to facilitate drainage, and the rock wool board of the insulation layer cooperates with the limiting plate of the inner wall of the outer shell through the groove, so that the structure is stable. At the same time, the interface treatment layer also plays a corresponding role. This structure enables the structural panel to not only effectively block external moisture, but also properly deal with internal water vapor condensation. It avoids durability problems such as insulation layer corrosion, mildew and failure of interlayer bonding caused by water infiltration, effectively extending the service life of the structural panel, ensuring building quality and structural safety, and meeting the comprehensive needs of modern buildings.

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a waterproof structure for building insulation and decorative structural panels. For example... Figure 1 , Figure 3 As shown, it includes an outer shell 1, and an insulation board body 6 is provided on the inner side of the outer shell 1. The outer shell 1 is the protective shell of the entire structure, providing physical support and protection for many internal components. The insulation board body 6 is arranged from the outside to the inside as an outer protective layer, a first waterproof layer, an insulation layer, a second waterproof layer, and an interface treatment layer.

[0023] See Figure 3 As shown, the outer protective layer is a ceramic thin plate 601 with a thickness of 3-5mm. The ceramic thin plate 601 has good physical properties and can resist some impacts and frictions from the outside. At the same time, it is also the first line of defense to prevent external moisture and other substances from entering the interior of the structure. With its relatively dense material properties, it can prevent moisture from directly contacting other internal structural layers as much as possible.

[0024] In this embodiment, the first waterproof layer is a polymer self-adhesive waterproof membrane 602 with a thickness of 1.5mm. The polymer self-adhesive waterproof membrane 602 has excellent waterproof performance. Relying on its special polymer material and self-adhesive properties, it is tightly bonded to its adjacent structural layers. When a small amount of water breaks through the outer protective layer composed of ceramic thin plate 601, it can play a blocking role in time to prevent water from further penetrating inward, forming a second strong barrier for structural seepage prevention.

[0025] In this embodiment, the insulation layer is rock wool board 604. Polymer-modified cement-based mortar 603 is provided between the polymer self-adhesive waterproof membrane 602 and the insulation layer rock wool board 604. Grooves are provided on both sides of the rock wool board 604, and limiting plates 7 are provided in the grooves. The limiting plates 7 are installed on the inner wall of the outer shell 1 to ensure the stability of the rock wool board 604 in the structure, so that it can stably play the role of insulation, and can also maintain the integrity of the entire structure through cooperation with other components. Rock wool board 604 itself is a high-quality insulation material that can effectively prevent heat transfer and plays a key role in ensuring the thermal insulation performance of buildings.

[0026] In this embodiment, the second waterproof layer is set as a breathable waterproof membrane 605. The breathable waterproof membrane 605 is made of thermoplastic polyurethane and has a thickness of 0.3-1.2mm. While preventing water from penetrating inward, the breathable waterproof membrane 605 also has a certain degree of breathability, which can balance environmental factors such as humidity inside the structure. Even if a very small amount of water breaks through the first waterproof layer and enters the area where the insulation layer is located, it can play a final "interception" role, preventing water from continuing to penetrate inward and ensuring that water will not penetrate into the interior of the structure and affect the insulation and other performance. It is an indispensable and important link in the entire seepage prevention system.

[0027] In this embodiment, the interface treatment layer consists of an interface agent 606 and an alkali-resistant mesh 607. The interface agent 606 is a polymer-modified mortar with a thickness of 1-2 mm, and the alkali-resistant mesh 607 is a standard fiberglass mesh with a total thickness of 0.3-0.5 mm. This enhances the bonding performance between different structural layers, allowing the layers of the entire insulation board body 6 to be tightly bonded together to form a stable whole. This avoids delamination and other situations that affect structural performance, and also helps to improve the durability of the entire structure.

[0028] See Figure 1 , Figure 2 , Figure 4As shown, a high-strength crack-resistant mortar board 5 is provided on the front side of the insulation board body 6. A flow guiding component is provided between the high-strength crack-resistant mortar board 5 and the outer shell 1. The flow guiding component includes a fixing plate 2, which is fixedly connected to the outer shell 1 by screws 4. A flow guiding plate 3 is installed on the front side of the fixing plate 2. The flow guiding plate 3 is inclined and is located on the outside of the high-strength crack-resistant mortar board 5. Since the flow guiding plate 3 is installed on the outer shell 1 through the stable fixing plate 2, it can reliably guide the water flow to the appropriate direction, avoiding water from accumulating on the surface of the high-strength crack-resistant mortar board 5 for a long time or seeping into the interior of the structure, thereby better ensuring the seepage prevention performance and structural stability of the entire structure.

[0029] The implementation principle of the waterproof structure of the building insulation and decorative structural board in this application embodiment is as follows: When water comes into contact with the structural board, it will first fall on the surface of the outer protective layer composed of ceramic thin plate 601. If a small amount of water penetrates through the outer protective layer, it will be blocked by the first waterproof layer of polymer self-adhesive waterproof membrane 602 to prevent water from penetrating further inward. Even if a very small amount of water breaks through the first waterproof layer and enters the area where the insulation layer is located, the second waterproof layer breathable waterproof membrane 605 will also play a role in preventing water from continuing to penetrate inward, ensuring that water will not penetrate into the interior of the structure and affect the insulation and other performance.

[0030] When encountering rainfall or other situations, when water flows over the surface of the structure, the water will flow along the inclined guide plate 3. The guide plate 3 is firmly installed on the outer shell 1 through the fixing plate 2, which can guide the water flow to the appropriate direction and prevent the water flow from accumulating on the surface of the high-strength crack-resistant mortar board 5 for a long time or seeping into the interior of the structure, thereby better ensuring the waterproof performance and structural stability of the entire structure.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
