Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of color steel corrugated board, especially to a polyurethane heat preservation and waterproof color steel corrugated board applied to industrial plants. BACKGROUND

[0002] Corrugated board is a building material widely used in industrial construction and plant construction, especially in roofing and wall systems. Corrugated board is made by pressing metal sheets through a profiling process, presenting a unique wave-shaped corrugated structure. The shape of the corrugation not only gives it an aesthetic appearance, but also significantly improves its structural performance, making it perform better in load bearing, wind resistance, and seismic resistance. The emergence and development of corrugated board provide an economic, efficient, and practical solution for industrial construction, and it is one of the indispensable materials in modern architecture.

[0003] The most distinctive feature of corrugated board is its wavy corrugated structure on the surface. This structure can be formed by plastic processing of metal sheets through a profiling machine. According to different types of sheets, common corrugated board materials include steel, aluminum, galvanized steel sheet, stainless steel, etc. Among them, galvanized steel sheet is the most widely used in industrial construction due to its good corrosion resistance and cost-effectiveness.

[0004] The design structure of corrugated board is generally divided into several different corrugated shapes, the most common of which are three types:

[0005] Single corrugation: refers to only one trough between each peak. This design is simple and low-cost, suitable for small-area or low-load-bearing buildings.

[0006] Double corrugation: refers to two troughs between each two peaks. This design increases the strength of the sheet and is widely used in buildings that need to bear heavy loads.

[0007] Triple corrugation: this corrugated board design uses multiple troughs and peaks, with high load-bearing capacity and stability, usually used in high-strength buildings.

[0008] In addition to differences in shape and structure, the thickness of corrugated board is also an important factor in determining its performance. Common thicknesses are generally between 0.3mm and 1mm, and the specific choice depends on the actual needs of the building.

[0009] As a building material, corrugated board has many excellent properties that make it highly valuable in the field of industrial construction.

[0010] Corrugated sheets effectively increase the strength and rigidity of the sheet through its unique wavy structure. In roofing systems, corrugated sheets not only bear the weight of the building itself but also resist external loads such as wind and snow. Therefore, corrugated sheets can be used stably on large-span and large-area roofs, reducing the need for structural support.

[0011] Due to its unique wavy structure, corrugated sheets exhibit good wind resistance under wind pressure. In strong wind weather, corrugated sheets can effectively disperse wind pressure, avoiding damage caused by wind concentration. In addition, the rigidity and elasticity of corrugated sheets make them better at dispersing vibrations in earthquakes, thereby increasing the seismic capacity of buildings.

[0012] Corrugated sheets themselves have a lower self-weight, usually much lighter than traditional concrete or brick walls, thus reducing the overall burden of the building. Especially in industrial plants that require large-span, light-weight roofing systems, the use of corrugated sheets can reduce the need for steel structural support, thereby reducing construction costs. In addition, the smooth surface of corrugated sheets can effectively reflect sunlight, having certain energy-saving effects.

[0013] The corrosion resistance of corrugated sheets depends largely on the metal material used and the surface treatment method. Galvanized corrugated sheets, by coating a zinc layer, perform outstandingly in terms of corrosion resistance, effectively resisting oxidation, acid and alkali corrosion and other factors in the external environment, thereby prolonging the service life. At the same time, the design of corrugated sheets can also prevent water accumulation, reducing the risk of corrosion.

[0014] Due to its wavy structure, corrugated sheets have good sound insulation performance to some extent, especially in noisy environments, they can effectively reduce noise transmission. In addition, the multi-layer structure of corrugated sheets also has good thermal insulation performance, which can reduce heat conduction and effectively improve the energy utilization efficiency of buildings.

[0015] Corrugated sheets are widely used in various industrial buildings, warehouses, commercial buildings and other fields, and their unique advantages make them perform well in many aspects.

[0016] Corrugated sheets are widely used in the roofing and wall systems of industrial plants and warehouses. In particular, in steel structure plants, corrugated sheets are used as roofing, exterior walls and enclosure structures, providing high strength and rigidity to ensure the stability and safety of the building. The waterproof performance of corrugated sheets also makes it an ideal roofing material in areas with more rain.

[0017] Corrugated sheets are also widely used in the agricultural field, especially in greenhouse and greenhouse construction. They have good light transmission and can provide suitable lighting conditions to promote plant growth. In addition, corrugated sheets have strong wind resistance and pressure resistance, which can effectively prevent damage to greenhouses in strong wind weather.

[0018] With the popularization of green building and sustainable development concept, corrugated board is also gradually applied in commercial buildings. Through its good heat and sound insulation performance, corrugated board provides effective guarantee in energy saving and comfort. In addition, the appearance design of corrugated board is modern and beautiful, which meets the aesthetic needs of many commercial buildings.

[0019] Corrugated board is also applied in the construction of some traffic facilities, especially in the roofing system of large facilities such as bridges, stations and airports. Corrugated board can effectively improve the overall strength of the building and ensure the safe operation of traffic facilities.

[0020] The construction of corrugated board is usually simple, which is one of the reasons for its wide application. Corrugated board can be directly installed on the roof and wall through special lock and connection method, with short construction period and low labor cost. However, corrugated board needs regular inspection and maintenance during use. Especially for corrugated board exposed to the outside for a long time, attention should be paid to whether there are cracks, corrosion and other problems on the surface to ensure its good performance.

[0021] With its excellent strength, rigidity, wind resistance, corrosion resistance and other characteristics, corrugated board has become a widely used building material in modern industrial buildings, warehouses, commercial buildings and other fields. With the continuous progress of technology and the continuous improvement of production process, the performance of corrugated board will be more perfect, and the application field will be further expanded. Through reasonable design and maintenance, corrugated board can provide stable, safe, economic and environmentally friendly solutions for buildings.

[0022] The existing corrugated board installation steps are numerous, and various tools are needed for fixing. The splicing process needs a lot of pretreatment of the plate, which increases the construction time and cost, and affects the splicing efficiency. SUMMARY

[0023] In order to make up for the above shortcomings, the utility model provides a polyurethane heat preservation and waterproof color steel corrugated board applied in industrial plant, which aims at improving the problem that the existing corrugated board has many installation steps and affects splicing efficiency.

This design ensures that the corrugated boards can be accurately inserted between them, thereby improving the overall structural stability.

[0050] The design of the slot and the limiting block makes it difficult to misalign during installation, avoiding poor sealing or tight joints caused by improper installation.

[0051] The clamping groove further enhances the stability of the connection, making the connection between the two plates more secure.

[0052] 5. Stable structure of fixing block and connecting groove
