Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically a rock wool fireproof sandwich panel for color steel houses. Background Technology

[0002] Prefabricated steel houses are a new type of environmentally friendly and economical building constructed using light steel H-beams and channel steel as the frame, sandwich panels as the wall material, and standardized modular panels for spatial assembly. Existing prefabricated steel houses commonly use metal sandwich panels as the wall and roof material. As a crucial component of prefabricated steel houses, sandwich panels offer numerous advantages, including light weight, ease of processing, and good economic efficiency.

[0003] To reduce the overall weight of sandwich panels and improve their thermal insulation properties, lightweight foam is often used to fill the inner layer of the sandwich panels. However, the flammable nature of foam can significantly reduce the fire resistance of the sandwich panels, making them more susceptible to accelerated fire spread in the event of a fire. Furthermore, since foam is a soft filler, its support properties are poor, resulting in a significant reduction in the central support strength of the sandwich panels. Therefore, a rock wool fireproof sandwich panel for color steel houses is proposed. Utility Model Content

Example

[0026] Please see Figure 1-5 This utility model provides a technical solution: a rock wool fireproof sandwich panel for color steel house construction, including an inner panel mechanism and an outer panel mechanism. The inner panel mechanism is used for fireproofing and flame retardancy on the inner side of the sandwich panel. The inner panel mechanism includes an inner panel filling part 5, a rock wool inner panel 6, an inner fireproof sheet layer 7, and an alloy edge plate 8. The rock wool inner panel 6 and the inner fireproof sheet layer 7 are respectively disposed on the inner sandwich side and the outer edge side of the inner panel filling part 5. Specifically, see attached figure. Figure 5As shown, the rock wool inner board 6 is a solid rock wool board in sheet form, which has good flame retardant and heat insulation properties. The inner board filling part 5 can be made of lightweight polyurethane foam. The inner board filling part 5 is integrally fixed and wrapped around the outside of the rock wool inner board 6, which can improve the heat insulation properties of the sandwich panel. The inner fireproof sheet layer 7 is a pair of rock wool mesh sheets. The two sets of inner fireproof sheet layers 7 are respectively fixed and installed on both sides of the inner board filling part 5, which can provide flame retardant isolation protection for the edges of the inner board filling part 5. The rock wool inner board 6 is set in the middle of the inner board filling, and together with the fireproof sheet layer set on the boundary side, it forms a layered flame retardant and fireproof structure, which can effectively improve the flame retardant and fireproof properties of the sandwich panel.

[0027] Alloy edge plate 8 is disposed on the edge plate portion of the inner panel filling part 5, for shielding and protecting the edge plate portion of the inner panel filling part 5, as detailed in the attached figure. Figure 5 As shown, the alloy edge plate 8 is a pair of stainless steel plates. The two sets of alloy edge plates 8 are fixedly installed on the two end plates of the inner plate filling part 5. In order to facilitate stable installation with the inner plate filling part 5, a mating insert is provided on the inner edge of the alloy edge plate 8. After installation, the inner plate filling part 5 and the mating insert are integrated and installed together.

[0028] The outer panel mechanism is integrally clamped and installed on both sides of the inner panel mechanism for external support and protection. The outer panel mechanism includes a pair of outer panel filling parts 1, reinforcing strips 2, an outer fireproof sheet layer 3, and a color steel guard plate 4. The outer panel filling part 1 can be made of lightweight polyurethane foam. The reinforcing strips 2 and the color steel guard plate 4 are respectively set on the inner interlayer side and the outer edge side of the outer panel filling part 1. For details, see attached. Figure 4 As shown, the reinforcing strip 2 can be made of plastic or metal. To improve the support characteristics, a rounded protrusion is set in the middle of the reinforcing strip 2. Multiple reinforcing strips 2 are provided and installed in an equidistant manner. The outer panel filling part 1 is integrally covered with the outside of the reinforcing strip 2. The rounded support structure on the upper part of the reinforcing strip 2 can improve the structural support characteristics of the middle part of the sandwich panel and effectively enhance the structural support strength of the sandwich panel. The color steel guard plate 4 is integrally covered with the outer edge of the outer panel filling part 1 by adhesive to shield and protect the inner core. The outer fireproof sheet layer 3 is a rock wool mesh. The outer fireproof sheet layer 3 is fixedly clamped and installed on the installation sandwich side between the color steel guard plate 4 and the outer panel filling part 1, which provides flame-retardant isolation protection for the inner outer panel filling part 1.

[0029] The inner edge of the outer panel filling part 1 is fixedly installed with the inner fireproof sheet layer 7, as detailed in the attached document. Figure 2As shown, the inner side of the outer panel filling part 1 is fixedly installed with the inner fireproof sheet layer 7 by adhesive pressing, so that the inner and outer panels form an integrated composite core panel structure. The inner and outer double-layer panel structure is adopted. The inner panel mechanism is installed by the outer panels distributed on both sides. Through the support and protection of the outer panel mechanism, the inner rock wool inner panel 6 can be prevented from being damaged by external forces, which greatly improves the working reliability of the sandwich panel. In order to achieve the edge panel docking, a docking fold is provided on the edge of the color steel guard plate 4. After installation, the edge part of the alloy edge plate 8 is fixedly installed with the outer edge of the docking fold by adhesive pressing. The adhesive sealing of the alloy edge plate 8 and the edge fold of the color steel guard plate 4 can effectively improve the edge sealing of the sandwich panel, prevent rainwater infiltration and erosion, and greatly extend the service life of the sandwich panel.

[0030] Working principle or structural principle: During processing, after the inner and outer plate mechanisms are processed, adhesive is applied to the joint side of the inner and outer plates and the splicing side of the alloy edge plate 8. Then, the two sets of outer plates are installed on both sides of the inner plate by butt pressing. After that, the side roll pressing completes the integral bonding and installation of the alloy edge plate 8 and the 4-fold edge of the color steel guard plate, thus completing the splicing process of the sandwich panel.

[0031] During installation, the sandwich panels are assembled and installed by using grooved joints and bolts for fastening. When the inner and outer sides of the sandwich panels are subjected to impact, the outer shell is supported and protected by the color steel guard plate 4, while the inner arc support structure of the reinforcing strip plate 2 can improve the structural support characteristics of the middle of the sandwich panel and prevent damage to the inner rock wool board 6. In the event of a fire, the color steel guard plate 4 isolates the fire source on the outside, and the flame-retardant protective layer composed of the outer fireproof sheet layer 3 and the inner fireproof sheet layer 7 in the middle isolates the spontaneous combustion flame of the filling part to prevent the spread of the flame. At the same time, the separation of the inner rock wool board 6 in the inner layer can prevent the flame from spreading to the other side of the board layer, achieving efficient flame-retardant isolation of the fire source and effectively improving the flame-retardant and fireproof characteristics of the sandwich panel.

[0032] In summary, this sandwich panel adopts a double-layer structure with inner and outer panels. A reinforcing strip 2 is installed within the filling section of the outer panel. The arc-shaped support structure on the upper part of the reinforcing strip 2 enhances the structural support characteristics of the middle section of the sandwich panel, effectively improving its structural strength. The inner panel mechanism is clamped and installed by the outer panels distributed on both sides. An alloy edge plate 8 is installed on the edge joint of the inner and outer panels. The bonding and sealing between the alloy edge plate 8 and the edge fold of the color steel protective plate 4 effectively improves the edge sealing of the sandwich panel. A rock wool inner panel 6 is installed in the middle of the inner panel filling, which, together with the fireproof sheet layer on the boundary side, forms a layered flame-retardant and fireproof structure. This effectively improves the flame-retardant and fireproof characteristics of the sandwich panel. Furthermore, the support and protection of the outer panel mechanism prevents the inner rock wool inner panel 6 from being damaged by external forces, greatly improving the working reliability of the sandwich panel.
