Description

Technical Field

[0001] This utility model relates to the field of composite wall panel technology, and in particular to a cement fiber composite exterior wall panel based on a capillary absorbent board. Background Technology

[0002] In accordance with the national "dual carbon" target and the State Grid's green construction requirements, most substation buildings now use steel frames, and the exterior wall panels of these steel frames are primarily made of cement fiber composite panels. Traditional cement fiber composite exterior wall panels ( Figure 2 This type of exterior wall panel consists of two layers of cement fiber precast concrete boards with rock wool sandwiched in between, forming the inner wall panel. The outer wall panel is then formed by adding a 160mm adjustable cavity containing an internal external wall keel and a single-sided cement fiber precast concrete board. The purpose of the cavity in traditional exterior wall panels is to prevent or reduce rainwater seepage into the interior, resulting in a thickness of approximately 300mm. This thickness and weight make transportation and installation inconvenient. Furthermore, traditional exterior wall panels have poor waterproofing, allowing rainwater to easily penetrate. When rainwater seeps into the keel within the cavity, it is prone to rust, corrosion, or localized deformation and breakage, severely impacting its lifespan. Rust, corrosion, or localized deformation and breakage of the keel within the cavity are difficult to detect, posing a safety hazard. Rainwater seepage into the rock wool causes it to fail, reducing its thermal insulation, fire safety, sound absorption, noise reduction, and moisture and mildew resistance, also posing a safety hazard. Utility Model Content

[0003] The present invention provides a cement fiber composite exterior wall panel based on a capillary water-absorbing board, which is thin, lightweight and waterproof.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model discloses a cement fiber composite exterior wall panel based on a capillary absorbent board, comprising a cement fiber inner wall panel, a fiber-reinforced silicate inner panel, a light steel keel rock wool layer, a fiber-reinforced silicate outer panel, and a cement fiber exterior wall panel arranged sequentially. A stainless steel plate and a capillary absorbent board are disposed between the fiber-reinforced silicate outer panel and the cement fiber exterior wall panel. The stainless steel plate is disposed close to the fiber-reinforced silicate outer panel, and the capillary absorbent board is disposed close to the cement fiber exterior wall panel.

[0006] Furthermore, the thickness of the capillary absorbent plate is 5mm.

[0007] Furthermore, the thickness of the stainless steel plate is 0.5 mm.

[0008] Furthermore, the thickness of the cement fiber interior wall panel is 5mm, and the thickness of the cement fiber exterior wall panel is 15mm.

[0009] Furthermore, the thickness of the fiber-reinforced silicate inner plate and the fiber-reinforced silicate outer plate is 9 mm.

[0010] Furthermore, a polyurethane waterproof membrane is provided between the fiber-reinforced silicate outer plate and the stainless steel plate.

[0011] Furthermore, the thickness of the polyurethane waterproof membrane is 2mm.

[0012] Furthermore, a tin foil layer is provided between the fiber-reinforced silicate inner plate and the light steel keel rock wool layer.

[0013] Furthermore, the light steel keel rock wool layer includes a light steel keel and a rock wool layer. The rock wool layer is filled inside the light steel keel. The top of the light steel keel is bolted to the roof beam, and the bottom of the light steel keel is nailed to the roof floor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application discloses a cement fiber composite exterior wall panel based on a capillary absorbent board, suitable for the exterior walls of medium to large-sized substations. The integrated, press-fit composite wall panel, composed of a cement fiber inner wall panel, a fiber-reinforced silicate inner panel, a light steel keel rock wool layer, a fiber-reinforced silicate outer panel, a stainless steel plate, a capillary absorbent board, and a cement fiber outer wall panel, avoids the need for a 160mm adjustment cavity with an internal external keel in traditional cement fiber composite exterior wall panels, significantly reducing the thickness and weight of the cement fiber composite exterior wall panel. Specifically, a stainless steel plate and a capillary absorbent board are positioned between the fiber-reinforced silicate outer panel and the cement fiber outer wall panel, with the stainless steel plate on the inner side and the capillary absorbent board on the outer side. When water seeps into the outermost layer of the cement fiber composite exterior wall panel, the capillary absorbent board quickly absorbs it. The water then flows away under gravity, preventing it from penetrating further into the inner stainless steel plate and light steel keel rock wool layer. This prevents water from seeping into the light steel keel rock wool layer, causing corrosion, rust, or localized deformation and breakage, ultimately leading to the failure of the light steel keel rock wool layer. This effectively protects the inner light steel keel rock wool layer and increases the service life of the cement fiber composite exterior wall panel. The stainless steel plate blocks water from entering the fiber-reinforced silicate outer panel, further preventing water from penetrating the light steel keel rock wool layer and causing corrosion, rust, or localized deformation and breakage, thus significantly increasing the service life of the cement fiber composite exterior wall panel. In summary, the cement fiber composite exterior wall panel based on capillary absorbent board of this application has the characteristics of small thickness and light weight, which reduces the overall weight of the exterior wall by up to 30 kg per square meter and reduces the wall thickness by about 150 mm, making it easier to transport and install. The cement fiber composite exterior wall panel based on capillary absorbent board of this application has good waterproof performance, effectively protects the light steel keel rock wool layer, and ensures the thermal insulation, fire safety, sound absorption and noise reduction, and moisture and mildew prevention performance of the light steel keel rock wool layer, thus ensuring the safety performance of the cement fiber composite exterior wall panel and greatly increasing its service life.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1As shown, this embodiment provides a cement fiber composite exterior wall panel based on a capillary absorbent board, comprising a cement fiber inner wall panel 1, a fiber-reinforced silicate inner panel 2, a light steel keel rock wool layer 3, a fiber-reinforced silicate outer panel 4, and a cement fiber exterior wall panel 6 arranged sequentially. A stainless steel plate and a capillary absorbent board 5 are disposed between the fiber-reinforced silicate outer panel 4 and the cement fiber exterior wall panel 6. The stainless steel plate is positioned close to the fiber-reinforced silicate outer panel 4, and the capillary absorbent board 5 is positioned close to the cement fiber exterior wall panel 6. The thickness of the capillary absorbent board 5 is 4mm-6mm, such as 4mm, 5mm, or 6mm. The thickness of the stainless steel plate is 0.4mm-1.0mm, such as 0.4mm, 0.5mm, or 1.0mm. The thickness of the cement fiber inner wall panel 1 is 4mm-6mm, such as 4mm, 5mm, or 6mm. The thickness of the cement fiber exterior wall panel 6 is 10mm-16mm, such as 10mm, 15mm, or 16mm. The thickness of the fiber-reinforced silicate inner panel 2 and the fiber-reinforced silicate outer panel 4 is 7mm-10mm, such as 7mm, 9mm, and 10mm. The thickness of the polyurethane waterproof board is 2mm-5mm, such as 2mm, 3mm, and 5mm. The stainless steel plate is placed close to the fiber-reinforced silicate outer panel 4, and the capillary absorbent board 5 is placed close to the cement fiber outer wall panel 6, with the stainless steel plate being closer to the inner layer than the capillary absorbent board 5. The materials of each layer can adopt existing technologies and solutions, such as prefabrication in the factory by hot-pressing composite bonding with keel to form an integrated wall panel. The cement fiber inner wall panel 1 and the fiber-reinforced silicate inner panel 2 are hot-pressed composite bonded, the fiber-reinforced silicate inner panel 2, the fiber-reinforced silicate outer panel 4, and the light steel keel rock wool layer 3 are connected by keel screws, and the fiber-reinforced silicate outer panel 4, the stainless steel plate, the capillary absorbent board 5, and the cement fiber outer wall panel are hot-pressed composite bonded.

[0024] A cement fiber composite exterior wall panel based on the above structure and a capillary absorbent board is suitable for the exterior walls of medium and large substations. This integrated composite wall panel, composed of a cement fiber inner wall panel 1, a fiber-reinforced silicate inner panel 2, a light steel keel rock wool layer 3, a fiber-reinforced silicate outer panel 4, a stainless steel plate, a capillary absorbent board 5, and a cement fiber exterior wall panel 6, avoids the need for a 160mm adjustment cavity with an internal external keel in traditional cement fiber composite exterior wall panels, significantly reducing the thickness and weight of the cement fiber composite exterior wall panel. Specifically, a stainless steel plate and a capillary absorbent board 5 are placed between the fiber-reinforced silicate outer panel 4 and the cement fiber exterior wall panel 6, with the stainless steel plate on the inner side and the capillary absorbent board 5 on the outer side. When water seeps into the outermost cement fiber composite exterior wall panel 6, the capillary absorbent board 5 quickly absorbs it. The water then flows away under gravity, preventing it from penetrating further into the inner stainless steel plate and light steel keel rock wool layer 3. This prevents water from seeping into the light steel keel rock wool layer 3, causing rust, corrosion, or localized deformation and breakage, thus effectively protecting the inner light steel keel rock wool layer 3 and increasing the service life of the cement fiber composite exterior wall panel. The stainless steel plate blocks water from entering the fiber-reinforced silicate outer panel 4, further preventing water from penetrating the light steel keel rock wool layer 3 and causing rust, corrosion, or localized deformation and breakage, which would lead to the failure of the light steel keel rock wool layer 3. Combined with the capillary absorbent board 5, this significantly increases the service life of the cement fiber composite exterior wall panel. In summary, the cement fiber composite exterior wall panel based on capillary absorbent board of this application features a thinner profile and lighter weight, reducing the overall weight of the exterior wall by up to 30 kg per square meter and decreasing the wall thickness by approximately 150 mm, thus facilitating transportation and installation. The cement fiber composite exterior wall panel based on capillary absorbent board of this application exhibits excellent waterproofing, effectively protecting the light steel keel rock wool layer 3 and ensuring its thermal insulation, fire safety, sound absorption, noise reduction, and moisture and mildew resistance, thereby guaranteeing the safety performance of the cement fiber composite exterior wall panel and significantly increasing its service life. The cement fiber composite exterior wall panel based on capillary absorbent board of this application is particularly suitable for the exterior walls of medium and large-sized substations.

[0025] As one possible implementation method, such as Figure 1 As shown, the thickness of the capillary absorbent plate 5 is 5mm.

[0026] The 5mm thick capillary absorbent plate 5 has good water absorption while ensuring good stability.

[0029] As one possible implementation method, such as Figure 1 As shown, the thickness of the cement fiber interior wall panel 1 is 5mm, and the thickness of the cement fiber exterior wall panel 6 is 15mm.

[0030] Thinner cement fiber interior wall panels 1 can reduce the overall weight of the cement fiber composite exterior wall panels based on capillary absorbent boards, which is beneficial for processing and installation. Thicker cement fiber exterior wall panels 6 can provide better strength, resistance, fire resistance, water resistance and moisture resistance, effectively protecting the internal structure.

[0031] As one possible implementation method, such as Figure 1 As shown, the thickness of the fiber-reinforced silicate inner plate 2 and the fiber-reinforced silicate outer plate 4 is 9 mm.

[0033] As one possible implementation method, such as Figure 1 As shown, a polyurethane waterproof membrane is provided between the fiber-reinforced silicate outer plate 4 and the stainless steel plate.

[0034] Polyurethane waterproofing board possesses properties such as waterproofing, moisture resistance, thermal insulation, sound insulation, and fire safety, enhancing the moisture-proof, waterproof, and fire-resistant performance of the cement fiber composite exterior wall panel based on capillary absorbent board. The polyurethane waterproofing board can be hot-pressed and bonded between the fiber-reinforced silicate outer panel 4 and the stainless steel plate.

[0035] As one possible implementation, the thickness of the polyurethane waterproof membrane is 2mm.

The tin foil layer can be hot-pressed and bonded to the fiber-reinforced silicate inner panel 2.

[0039] As one possible implementation method, such as Figure 1As shown, the light steel keel rock wool layer 3 includes a light steel keel 301 and a rock wool layer 302. The rock wool layer 302 is filled inside the light steel keel 301. The top of the light steel keel 301 is fixedly connected to the roof beam of the substation by bolts, and the bottom of the light steel keel 301 is fixedly connected to the roof of the substation by nails.

[0040] The rock wool layer 302 can be installed inside the light steel keel 301 via a snap-fit ​​connection. The top of the light steel keel 301 is fixed to the roof beam of the substation with bolts, facilitating position adjustment during installation and improving overall installation efficiency. The bottom of the light steel keel 301 is fixed to the substation roof by driving nails into it with a nail gun, enhancing impact resistance and thus improving stability. This eliminates the need for welding on-site, enabling flameless installation and eliminating safety risks.
