Color steel sandwich plate

Abstract

The invention discloses a color steel sandwich plate. The color steel sandwich plate is characterized by being provided with a first color steel plate body, a first silicon dioxide aerogel layer, a foam glass layer, a second silicon dioxide aerogel layer and a second color steel plate body in sequence from left to right; reinforcing materials are arranged in the first silicon dioxide aerogel layer and the second silicon dioxide aerogel layer in the direction perpendicular to the color steel sandwich plate; an upper positioning clamping plate and a lower positioning clamping plate are arranged on the upper and lower edges of the color steel sandwich plate correspondingly; a flange is arranged on the upper positioning clamping plate; and a groove used for storing the flange is formed in the lower positioning clamping plate.

Description

technical field [0001] The invention relates to a color steel sandwich panel, in particular to a color steel sandwich panel with high structural strength, strong compression resistance and convenient installation. Background technique [0002] Color steel sandwich panel is the basic material for building clean rooms such as purification workshops and operating rooms. The clean room of a large factory generally has a height of more than 7 meters, so the main wall of the color steel sandwich panel also needs to be more than 7 meters. At present, the mainstream structure of this kind of main wall is composed of multiple composite color steel plates with the same height as the clean room, which are horizontally spliced. Since the composite color steel plates are located on the ground and reach the above height, the overall weight of more than 400kg is average. It is borne by its bottom, and the upper part is prone to bending deformation. Long-term deformation will increase the ...

Problems solved by technology

[0005] At present, the board cores used in color steel sandwich panels are mainly phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, three-polyurethane and rock wool, etc., but these core materials still have many disadvantages when used, such as polyurethane is flammable , will release dense smoke containing hydrogen cyanide when burning

Also, when color steel sandwich panels are used as building walls and roofs, if the steel plate layer is damaged and water seeps in, the volume will expand several times, causing serious deformation of color steel plates and damaging the building quality.

[0006] The color steel sandwich panels in the prior art generally only pay attention to thermal insulation performance, and do not pay too much attention to fire prevention, waterproof, compression resistance, impact resistance and sound insulation performance, so color steel panels can generally only be used for temporary buildings or simple factory buildings, and due to existing The service life of color steel sandwich panels with advanced technology is short, which greatly limits the development and market of color steel sandwich panels
