Description

Technical Field

[0001] This utility model relates to the field of color steel plate sealing technology, specifically a purification color steel plate structure with high sealing performance. Background Technology

[0002] Color-coated steel refers to pre-painted steel sheets, which are steel sheets with an organic coating. They have advantages such as good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, and the original strength of steel sheets, as well as low cost. When installing color-coated steel sheets, it is necessary to seal the joints, thus providing a highly sealed cleanroom color-coated steel sheet structure.

[0003] For example, a type of color-coated steel sheet with a sealed structure, as described in announcement number "CN218892311U," combines the advantages of zinc, aluminum, and magnesium substrates in its body, increasing the sheet's mechanical properties. An anti-corrosion layer further enhances its corrosion resistance. The sealing structure and the sheet itself work synergistically to improve waterproofing. The process is simple and has high practical value. However, the sealing method described above only applies unidirectional force through sealant and bolts, resulting in a low sealing effect and poor unidirectional stability, thus reducing the overall sealing quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that color steel plates can only be sealed by applying force in one direction with sealant and bolts, which has a low sealing effect and poor unidirectional fixing stability, thus reducing the sealing quality of the color steel plates. Therefore, a high-sealing purification color steel plate structure is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highly airtight cleanroom color steel plate structure is designed, comprising a first color steel plate and a second color steel plate, characterized in that: a color steel plate sealing structure is provided between the first color steel plate and the second color steel plate, the middle layer of the first color steel plate and the second color steel plate is a cold-rolled steel plate, and the upper surface of the cold-rolled steel plate is sprayed with a color coating.

[0007] Preferably, the color steel plate sealing structure includes a first hook, a second hook fixedly connected to the right end of the second color steel plate, a sealant spray nozzle on the inner wall of the second hook, the first hook and the second hook being hooked together, a plurality of crossbars fixedly connected to the left side of the inner wall of the first hook, the outer wall of the crossbars being inserted into the second hook, and the upper ends of the first hook and the second hook being threadedly connected to a plurality of bolts.

[0008] Preferably, the right end of the first hook is fixedly connected to the first color steel plate.

[0009] Preferably, the surface of the colored coating is coated with an anti-corrosion layer.

[0010] Preferably, a heat insulation layer is fixedly connected to the lower surface of the cold-rolled steel sheet.

[0011] This utility model proposes a highly airtight purification color steel plate structure, the beneficial effects of which are as follows: Through the color steel plate sealing structure, sealant is applied to the inside of the second hook using an external caulking gun, and a crossbar is inserted into the second hook. Then, the first steel plate is removed, and the first hook is hung in the second hook. The gap between the first hook and the second hook is filled with sealant. Multiple bolts are removed and their upper ends are turned into the first hook and the second hook. Sealant is applied to the inside of the second hook, and then the first hook and the second hook are hung together, with the crossbar limiting the second hook laterally. The connection between the first hook and the second hook is filled and sealed with sealant. By using bolts and a crossbar to rotate the first hook and the second hook respectively for fixation and lateral limitation, the connection between the first hook and the second hook at the color steel plate connection can be made more stable and tight, thereby improving the airtightness of the color steel plate.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5In this embodiment, a highly sealed purification color steel plate structure includes a first color steel plate 2 and a second color steel plate 3. A color steel plate sealing structure 1 is provided between the first color steel plate 2 and the second color steel plate 3. Through the anti-corrosion layer 5, the color coating layer 4, and the heat insulation layer 7, the color steel tile ensures its waterproof, corrosion-resistant, heat insulation, and noise reduction functions during the manufacturing and application process, thereby playing a purification role. After the first hook 101 and the second hook 103 are connected, the first color steel plate 2 can be fixed to the roof steel frame using external bolts. The middle layer of the first color steel plate 2 and the second color steel plate 3 is a cold-rolled steel plate 6. The upper surface of the cold-rolled steel plate 6 is sprayed with a color coating layer 4, which is a polyester coating. Polyester coating is one of the most commonly used coatings for color steel tiles and has good weather resistance, corrosion resistance, and color retention.

[0020] The right end of the first hook 101 is fixedly connected to the first color steel plate 2. The upper surface of the color coating 4 is sprayed with an anti-corrosion layer 5, which is made of polyurea anti-corrosion material. Polyurea anti-corrosion material has excellent aging resistance and media corrosion resistance, and can resist corrosion damage under natural conditions. Its service life is long, up to 30-50 years or even longer. The anti-corrosion layer 5 is made of transparent coating, so the color coating 4 can be seen through the anti-corrosion layer 5. The lower surface of the cold-rolled steel plate 6 is fixedly connected to a heat insulation layer 7, which is made of polystyrene foam (EPS). EPS has excellent thermal insulation performance, low thermal conductivity, and certain sound absorption performance, which can effectively reduce noise.

[0021] See attached document Figure 1-4 The color steel plate sealing structure 1 includes a first hook 101, and a second hook 103 is fixedly connected to the right end of the second color steel plate 3. The inner wall of the second hook 103 is sprayed with sealant 104, which is a neutral silicone sealant with good weather resistance, aging resistance, UV resistance and ozone resistance. It has no corrosive effect on steel plates and color coatings and is suitable for sealing between color steel plates or other materials. It is usually packaged in a tube and extruded using a pusher (squeezing gun). The first hook 101 and the second hook 103 are hooked together. Multiple crossbars 105 are fixedly connected to the left side of the inner wall of the first hook 101. The outer wall of the crossbars 105 is inserted into the second hook 103. The upper ends of the first hook 101 and the second hook 103 are threadedly connected to multiple bolts 102. The left sides of the first hook 101 and the second hook 103 are threadedly connected to multiple second bolts 105.

[0022] Working principle:

[0023] Sealing of the cleanroom-grade color steel plate:

[0024] When sealing the installation of color steel plates in building construction, firstly, use external bolts to fix the second color steel plate 3 to the steel frame of the roof. Then, use an external sealant applicator to apply sealant 104 inside the second hook 103 (e.g., ...). Figure 2Sealant 104 is a neutral silicone sealant: it has good weather resistance, anti-aging properties, UV resistance and ozone resistance, and has no corrosive effect on steel plates and color coatings. It is suitable for sealing between color steel plates or other materials. It is usually packaged in a tube and extruded using a pusher (squeeze gun).

[0025] Then, the first steel plate 2 is removed, and the multiple crossbars 105 are aligned with the grooves on the left side of the second hook 103. The first hook 101 is then hooked into the second hook 103, and the crossbars 105 are inserted into the second hook 103. (After forming) Figure 2 (In the connected state), the first hook 101 is restricted by the crossbar 105 to move only left and right. The gap between the first hook 101 and the second hook 103 is filled with sealant 104. After the sealant 104 has completely solidified, multiple bolts 101 are removed and their upper ends are turned into the first hook 101 and the second hook 103. This can fix the first hook 101 and the second hook 103. The bolts 101 and the crossbar 105 fix the first hook 101 and the second hook 103 and limit their lateral movement, making the connection more stable and tight, effectively improving the stability and sealing of the connection between the first color steel plate 2 and the second color steel plate 3.

[0026] The middle layer of the first color steel plate 2 and the second color steel plate 3 is a cold-rolled steel plate 6, and the upper surface is sprayed with a color coating 4. The color coating 4 is polyester: polyester coating is one of the most commonly used coatings for color steel tiles, with good weather resistance, corrosion resistance and color retention. The upper surface of the color coating 4 is sprayed with an anti-corrosion layer 5, which is a polyurea anti-corrosion material: polyurea anti-corrosion material has excellent aging resistance and media corrosion resistance, can resist corrosion damage under natural conditions, and has a long service life of 30-50 years or even longer. The anti-corrosion layer 5 is a transparent material, which can be seen through the anti-corrosion coating. The corrosion layer 5 is clearly visible. The color coating 4 is visible. The lower surface of the cold-rolled steel plate 6 is fixed with a heat insulation layer 7. The heat insulation layer 7 is made of polystyrene foam (EPS), which has excellent heat insulation and thermal insulation properties, low thermal conductivity, and certain sound absorption properties, which can effectively reduce noise. Through the above materials, the color steel tile ensures its waterproof, corrosion-resistant, heat insulation, noise reduction and thus plays a role in purification during the manufacturing and application process. After the first hook 101 and the second hook 103 are connected, the first color steel plate 2 can be fixed to the roof steel frame using external bolts.
