Description

Technical Field

[0001] This utility model relates to the field of building wall technology, and in particular to a moisture-proof and heat-insulating wall. Background Technology

[0002] Building walls, as a key component of a building, primarily function to ensure structural safety and partition interior spaces. Wall types are diverse, ranging from single-material constructions to composite material walls with enhanced moisture resistance and thermal insulation. When designing wall solutions, it's crucial to consider not only the final aesthetic effect but also how to achieve efficient and durable moisture resistance and thermal insulation.

[0003] For example, the Chinese patent published on December 15, 2023, entitled "A Moisture-proof and Thermal Insulation Structure Layer for Building Exterior Walls" (Publication No.: CN220184487U), discloses a thermal insulation protective layer installed on the front side of the exterior wall surface. This thermal insulation protective layer includes a leveling layer, an adhesive layer, a thermal insulation layer, and a crack-resistant layer. A moisture-proof layer is installed in front of the thermal insulation protective layer, comprising a fireproof layer, a waterproof layer, and a finishing layer. The crack-resistant layer is located in front of the thermal insulation layer, which in turn is located in front of the adhesive layer. The adhesive layer is located in front of the leveling layer. The leveling layer is made of mortar, the adhesive layer is made of a special adhesive, and the thermal insulation layer is made of expanded polystyrene board. Through the combined use of the exterior wall surface, thermal insulation protective layer, leveling layer, adhesive layer, thermal insulation layer, crack-resistant layer, mortar layer, mesh layer, moisture-proof layer, fireproof layer, waterproof layer, and finishing layer, the thermal insulation, moisture-proof, and fireproof performance of the exterior wall surface can be effectively improved, extending its service life.

[0004] Although the above-mentioned technologies include a fireproof layer, they do not include other fireproof structures. They rely solely on a single fireproof layer as a fire barrier. Furthermore, in existing technologies, most insulation layers use flammable organic materials. In actual fire scenarios, due to the lack of multi-dimensional fireproof structures working together, it is difficult to form an effective fire barrier network. Therefore, it cannot significantly slow down the spread of flames within the building, posing a fire safety hazard. Utility Model Content

[0005] The main purpose of this utility model is to provide a moisture-proof and heat-insulating wall, which solves the problem of relying on a single fireproof layer as a fire barrier in the existing technology, thus leaving fire hazards and improving the safety of the equipment.

[0006] The technical solution of this utility model is as follows:

[0007] A moisture-proof and heat-insulating wall includes a wall body, an exterior wall surface, and a heat-insulating protective layer. The heat-insulating protective layer is disposed within the wall body. A fireproof structure is provided between the exterior wall surface and the heat-insulating protective layer. The fireproof structure includes a fireproof gasket, a fireproof isolation strip, and a fireproof breathable layer.

[0008] The fireproof isolation strip is fixedly connected to the exterior wall surface, the fireproof breathable layer is provided with several breathable holes, the fireproof breathable layer is fixedly connected to the fireproof isolation strip, and the fireproof gasket is fixedly connected to the thermal insulation and protective layer on the exterior wall surface side.

[0009] In one possible implementation, the fireproof isolation strip and the fireproof breathable layer are horizontally disposed on the bottom of the exterior wall surface, and the fireproof isolation strip and the fireproof breathable layer are disposed adjacent to each other in the vertical direction of the exterior wall surface.

[0010] In one possible implementation, the fireproof and breathable layer has at least one layer, and each of the fireproof and breathable layers is alternately arranged with the fireproof isolation strip along the vertical direction of the exterior wall surface.

[0011] In one possible implementation, the fireproof structure further includes a fireproof coating, which is applied to the side of the thermal insulation layer facing the exterior wall.

[0012] In one possible implementation, the fireproof structure further includes a mesh fabric, which is laid on the side of the exterior wall facing the fire-resistant isolation zone.

[0013] In one possible implementation, the wall edge is provided with a connecting structure, the connecting structure including a female connecting part, a male connecting part, and a sealant layer, the female connecting part and the male connecting part being respectively located on opposite sides of the wall, and the sealant layer covering the surface of the male connecting part.

[0014] In one possible implementation, the fireproof pad is disposed along the inner edge of the wall.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] First, clean the exterior wall surface, reserve and position the installation location for the connecting structure, then horizontally fix the fireproof isolation strip to the wall surface, and alternately install at least two layers of fireproof and breathable layers. Simultaneously, apply a fireproof coating to the thermal insulation layer, install fireproof gaskets at the edges, and then fix the thermal insulation layer. Finally, align and fit the male and female connectors in the connecting structure to complete the moisture-proof and thermal insulation wall construction.

[0017] This embodiment creates a three-dimensional fire protection system by designing a fireproof structure within the wall, effectively preventing the spread of fire. The fireproof isolation strip is tightly fixed to the exterior wall surface, forming a physical barrier in the event of a fire and blocking the lateral spread of flames along the wall. The fireproof and breathable layer not only has good flame retardancy itself, but its vents also ensure that the wall can breathe while preventing moisture accumulation and enhancing moisture resistance. The various fireproof components work together to construct a three-dimensional and airtight fire protection system, giving this invention strong safety features. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-5As shown, this embodiment proposes a moisture-proof and heat-insulating wall, the structure of which includes a wall body 1, an outer wall surface 11, and a heat-insulating protective layer 2. The wall body 1 serves as the basic load-bearing structure and is the main frame of the entire embodiment. The heat-insulating protective layer 2 is located inside the wall body 1, which prevents the external environment from directly damaging the heat-insulating material, extends its service life, and the internal setting can reduce the impact of external temperature fluctuations on the heat-insulating protective layer 2, ensuring its heat-insulating stability.

[0029] A fireproof structure 3 is provided between the exterior wall 11 and the thermal insulation protective layer 2. In the prior art, most thermal insulation protective layers 2 are made of flammable organic materials. The fireproof structure 3 is located in this position to effectively block the direct threat of fire sources to the thermal insulation protective layer 2, and at the same time effectively prevent the fire from spreading to the outside after the thermal insulation material is burned, thus playing a two-way fireproof role.

[0030] like Figures 3-5 As shown, the fireproof structure 3 includes a fireproof gasket 31, a fireproof isolation strip 32, and a fireproof breathable layer 33. The fireproof isolation strip 32 is fixedly connected to the exterior wall surface 11, ensuring a tight fit between the fireproof isolation strip 32 and the exterior wall surface 11. This provides strong stability and effectively prevents the spread of flames along the gap between the exterior wall surface 11 and the fireproof isolation strip 32, separating the fire source from the thermal insulation layer 2 immediately. The fireproof breathable layer 33 has several ventilation holes 331, achieving ventilation without affecting the fireproof performance. The ventilation holes 331 ensure that moisture inside the wall 1 can be smoothly discharged, preventing the performance of the thermal insulation layer 2 from deteriorating due to moisture accumulation and maintaining the long-term function of the thermal insulation layer 2.

[0031] The fire-resistant and breathable layer 33 is fixedly connected to the fire-resistant isolation strip 32. The two are fixedly connected to form a stronger fire barrier and ensure the stability of the fire-resistant and breathable layer 33 in the wall 1, preventing the breathable layer from shifting due to external forces or environmental factors, which would affect the breathability and fire resistance. The fire-resistant gasket 31 is fixedly connected to the side of the thermal insulation protective layer 2 facing the outer wall surface 11. The fire-resistant gasket 31 is tightly attached to the thermal insulation protective layer 2, filling the gaps between the thermal insulation protective layer 2 and other components, preventing flames and heat from entering from the edge of the thermal insulation protective layer 2, and playing a role in sealing and fire prevention.

[0032] like Figure 4As shown, in this embodiment, the fire-resistant isolation strip 32 and the fire-resistant breathable layer 33 are horizontally aligned with the bottom of the exterior wall surface 11 and are installed on the exterior wall surface 11, forming a continuous and uniform horizontal fire barrier. This effectively prevents the flames from spreading horizontally along the exterior wall surface 11, especially in the early stages of a fire, confining the fire to a smaller area and reducing the risk of lateral fire spread. The fire-resistant isolation strip 32 and the fire-resistant breathable layer 33 are vertically adjacent to the exterior wall surface 11, creating a vertical fire-resistant and breathable composite protection system. This saves space in the wall 1 and achieves multiple functional integrations without increasing the wall 1's thickness, meeting building fire safety requirements while ensuring structural compactness and practicality. The fire-resistant isolation strip 32 and the fire-resistant breathable layer 33 are horizontally aligned with the bottom of the exterior wall surface 11 and alternately arranged vertically, forming a two-way fire barrier that effectively reduces the speed of flame spread and provides residents with more time to escape during a fire.

[0033] In this embodiment, the fire-resistant and breathable layer 33 has at least two layers. Compared with a single-layer structure, the multi-layer fire-resistant and breathable layer 33 significantly improves the wall's ability to resist fire and slows down the spread of fire. Each fire-resistant and breathable layer 33 is alternately arranged with the fire-resistant isolation strip 32 along the vertical direction of the exterior wall surface 11, forming an interlaced structure of "fire-resistant and breathable layer 33 - fire-resistant isolation strip 32 - fire-resistant and breathable layer 33". This layout makes the functions of the fire-resistant isolation strip 32 and the fire-resistant and breathable layer 33 complementary. The fire-resistant isolation strip 32 prioritizes blocking flames, while the fire-resistant and breathable layer 33 assists in preventing the spread of flames through the ventilation holes, while simultaneously expelling moisture, thus constructing a tight fire-resistant and breathable protective network in the vertical direction. Furthermore, the alternating arrangement ensures that the fire-resistant and breathable functions are evenly distributed in the vertical direction of the wall, avoiding weak areas in protection, and effectively blocking fires regardless of their origin.

[0034] In this embodiment, the fireproof isolation strip 32 can be made of rock wool board, which has the advantages of being made of basalt and other raw materials, achieving Class A non-combustible combustion performance, and having a low thermal conductivity (≤0.040W / (m·K)). It can effectively block the spread of flames, has heat preservation function, and is lightweight, chemically stable, and not easily deformed or detached after being fixed to the exterior wall surface.

[0035] In this embodiment, the fireproof and breathable layer 33 can be made of porous clay board. Its advantages are that it is made of natural clay and has dense interconnected pores inside. The fireproof rating reaches Class A, and the breathable pore structure is stable (pore diameter 0.1-0.5mm). It can not only ensure the discharge of water vapor, but also prevent the spread of flame through the high temperature resistance of clay. It is also resistant to aging, acid and alkali, and has a long service life.

[0036] In this embodiment, the fireproof structure 3 also includes a fireproof coating 34, further improving the fireproof structure 3. It works synergistically with the fireproof gasket 31, fireproof isolation strip 32, and fireproof breathable layer 33 to form multiple fire protection lines, enhancing overall fire resistance and reducing the time and risk of fire spread in the event of a fire. The fireproof coating 34 is located on the side of the insulation layer 2 facing the exterior wall 11, tightly covering the surface of the insulation layer 2, and directly protecting it. When an external fire occurs, the fireproof coating 34 can first block flames and heat, preventing the insulation material from burning due to high temperatures, effectively protecting the integrity of the insulation layer 2 and extending its service life.

[0037] In this embodiment, the fireproof coating 34 can be an intumescent fireproof coating, such as an organosilicon-modified acrylic resin base. Its advantage is that when exposed to fire, the coating rapidly expands to form a honeycomb carbonized heat insulation layer with a thickness of 50 to 200 times. The thermal conductivity can be reduced to below 0.05 W / (m·K). It can block heat conduction to the heat insulation and protection layer 2 in high-temperature environments above 300°C. By expanding when exposed to fire, it forms a heat insulation barrier and extends the fire protection time.

[0038] In this embodiment, the fireproof structure 3 also includes a mesh fabric 35, which is disposed on the side of the exterior wall 11 facing the fireproof isolation strip 32. The fiber network of the mesh fabric 35 can enhance the adhesion between the two layers of materials, prevent the fireproof isolation strip 32 from falling off or becoming hollow, and enhance the integrity and crack resistance of the fireproof structure 3.

[0039] In this embodiment, the mesh cloth 35 can be made of glass fiber mesh cloth, which has the advantage of being woven from medium-alkali or alkali-free glass fiber yarn. After being treated with alkali-resistant coating, it has a tensile strength of ≥1300N / 50mm, is resistant to high temperature (softening point ≥800℃) and alkali corrosion, and can be tightly attached to the exterior wall surface 11 and the fireproof isolation strip 32, effectively dispersing the deformation stress of the wall and preventing the joint from cracking.

[0040] like Figures 1-2 As shown, in this embodiment, the wall 1 has a connecting structure 4 at its edge. The connecting structure 4 includes a female connecting part 41, a male connecting part 42, and a sealing layer 43. These components, through a convex-concave fit, form a snap-fit ​​connection, ensuring that the wall 1 is not easily loosened or detached after assembly. The sealing layer 43, as a flexible sealing component, can fill the connection gaps. Its elastic material can adapt to minor deformations of the wall, reducing cracking problems caused by rigid connections. The female connecting part 41 and the male connecting part 42 are respectively located on opposite sides of the wall 1, facilitating quick positioning, alignment, and installation during construction. The sealing layer 43 covers the surface of the male connecting part 42. When the male connecting part 42 mates with the female connecting part 41, the sealing layer 43 is compressed and deformed, filling the connection gap. The elasticity of the sealing layer 43 can absorb minor displacements of the wall 1 caused by temperature changes, reducing wear on the connection points and extending the service life of the wall.

[0041] like Figure 4 As shown, in this embodiment, the fireproof pad 31 is set along the inner edge of the wall 1, and can also wrap the edge of the thermal insulation protective layer 2, which can reduce the invasion of fire source on the internal thermal insulation material and moisture-proof material of the wall 1, and at the same time seal the gap between the thermal insulation protective layer 2 and the wall 1 to prevent flames from passing through the gap.
