Description

Technical Field

[0001] The utility model belongs to the technical field of color steel plates, in particular to a fireproof and corrosion-resistant color steel plate. Background Art

[0002] Color steel plate is a composite material plate made of color-coated steel plate as the base material, coated with one or more layers of organic coating on the surface, and then heat-cured and cooled. Color steel plate is widely used in industrial plants, storage facilities, commercial buildings, office buildings, gymnasiums and other buildings. Color steel tiles, also known as color corrugated tiles, are made of color-coated steel plates, which are roll-rolled and cold-bent into various corrugated corrugated plates. It is suitable for industrial and civil buildings, warehouses, special buildings, roofs, walls, and interior and exterior wall decorations of large-span steel structure houses. It has the characteristics of light weight, high strength, rich colors, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long life, maintenance-free, etc., and has been widely promoted and applied.

[0003] Currently, the existing color steel tiles are installed on the roof, usually fixed directly to the beams with self-tapping screws. Due to the holes on the color steel tiles, the secondary utilization rate is greatly reduced. In addition, most of the color steel tiles are connected with lap screws at the splicing places, which easily leads to rainwater seeping in from the gaps where the screws are fixed when it rains.

[0004] A Chinese patent with publication number "CN218758316U" discloses a new type of waterproof colored steel tile, which is provided with a colored steel tile body, a placement cavity, thermal insulation cotton, a fixing mechanism and an assembly component. The thermal insulation cotton inside the placement cavity can effectively isolate the heat, thereby improving the overall thermal insulation performance of the colored steel tile body. By providing a fixing mechanism, the connection between the colored steel tile body and the beam can be made more firmly, thereby avoiding the use of self-tapping screws to directly fix the colored steel tile body on the beam. Due to the holes on the colored steel tile, the phenomenon of secondary utilization is greatly reduced. By providing an assembly component, two colored steel tile bodies can be easily spliced ​​with each other, thereby improving the splicing stability.

[0005] However, the whole is installed by bolt holes. Although the installation hole on the top is blocked by the connecting block, there is still a gap between the connecting block and the color steel tile. If there is a gap, there may be water leakage. It can be seen that its overall waterproof performance is not good, and its color steel tile structure is relatively simple. The overall fire prevention, waterproofing, thermal insulation and sound insulation capabilities are poor when in use, so it needs to be improved. Utility Model Content
