Description :

　　Steel skeleton lightweight board, Shenbo new type of concrete prefabricated panel assembly

　　The steel structure lightweight energy-saving composite roof panel is made of cold-formed thin-walled steel as the outer frame; Using steel truss or reinforced concrete as auxiliary ribs; Using high-performance ultra lightweight foam cement or other insulation materials as the core material; A new type of roofing material composed of alkali resistant glass fiber mesh reinforced polymer cement mortar (GRC) as the upper and lower layers.

　　The steel structure lightweight energy-saving composite roof panel not only inherits the reliability of traditional reinforced concrete slabs, abandons the factors of heavy weight and high energy consumption of traditional slabs, but also fully compensates for the defects of short service life, susceptibility to wind overturning, and lack of fire resistance of color steel plates. It meets the needs of modern light steel building roof construction and has become the choice for safe and durable roofs. It is an upgraded product of traditional roof panels.

　　Lightweight concrete sound-absorbing panels are rare, and most of them are sound-absorbing panels made of other materials. Steel skeleton lightweight panel is a new type of lightweight concrete sound-absorbing panel, which utilizes the special properties of foamed concrete core material. The reflection of incident sound energy by sound-absorbing materials is very small, and sound energy is easy to enter and pass through. The material of sound-absorbing materials should be porous, loose, and breathable, which is a typical porous sound-absorbing material. In the process, fibrous, granular, or foamed materials are usually used to form a porous structure; Its structural feature is that the material has a large number of interconnected micropores from the surface to the inside, which means it has a certain degree of breathability. When sound waves are incident on the surface of porous materials, they cause air vibrations in the micropores. Due to frictional resistance, air viscosity resistance, and thermal conduction, a considerable portion of the sound energy is converted into heat energy, thereby achieving sound absorption. Lightweight concrete sound-absorbing panel is defined in JC/T2122-2012 as a product with sound-absorbing function made mainly of cement and lightweight aggregate, with water and other materials added.
