History of sandwich board development

Sandwich board, as a new building material, is a self-supporting composite board composed of bimetal surface and insulation core material bonded between two metal surfaces. It can be seen in many industrial buildings. How did the sandwich board develop? Let's look at it together.

Sandwich plate origin:

Sandwich panels were first manufactured in the United States in 1947 to cover roofs and insulate homes, and have since been increasingly produced and used in a variety of applications.

With the discovery of sandwich boards, many insulators are using sandwich boards, and institutions are developing vigorously. Since the Second World War, some European countries in order to cure the war as soon as possible to the construction of severe trauma, in the early 1950s to vigorously promote the construction speed of assembled wall panel building. After the world energy crisis, most developed countries such as Europe and the United States, in order to reduce building energy consumption, which accounts for about 40% of the total energy consumption, have vigorously promoted energy-saving building, prefabricated wall panel building with high energy-saving rate and light insulation composite board building with steel structure in industrial and civil buildings since 1973. As a result, sandwich panels became more and more popular, and continue to be today.

The development of sandwich panel in China:

After 1979, cities such as Beijing, Tianjin, Shanghai and Shenyang should gradually realize industrial production, construction and assembly, installation and transportation mechanization of construction products, and widely adopt new materials, new products, new structures and new technologies. The development of rock wool, glass wool, gypsum board, asbestos cement board, composite board, aerated concrete board (block), sliding form, rising board, light aggregate concrete insulation large wall panel (also known as 62111 project). A large number of lightweight, high-strength residential buildings of new materials and structures have been built in Beijing and other places.

In 1980, China launched a number of directional predictive soft research projects, one of which is to predict China's residential floor area, residential thermal environment, building energy consumption in 2000. The conclusion of the study is: to make the national economy sustainable development and improve people's living standard, we must do well in building energy conservation. Therefore, sandwich plate in the domestic application is also more and more, its construction technology in the past 40 years has also made great progress.

Conclusion

Sandwich board has a lightweight, earthquake, fire prevention, waterproof, decoration, heat preservation, heat insulation, energy-saving and land-saving, material saving, board face, less joints, easy to install, fast construction, thin wall, more effective use of area, low comprehensive cost, long service life, low maintenance cost, this is a multifunctional composite plate, is now widely used in large industrial workshop, warehouse, gymnasium, supermarket, hospital, Cold storage, mobile room, building layer, clean workshop and need heat insulation fire prevention places. It has become an indispensable new lightweight building material.
