Abstract
The invention discloses a fire-resistant steel plate, which includes a steel plate layer and a fire-resistant layer, wherein the fire-resistant layer is a rankinite layer or a hard fiber layer; the outer side of the steel plate layer is wrapped with the fire-resistant layer; and the fire-resistant layer is adhered to the steel plate layer through silicate adhesive bonding agent, and is 5-15 mm in thickness. The fire-resistant plate provided by the application of the invention is simple in construction condition, has stable quality, is light as the fire-resistant steel plate is wrapped with the plate, has strong shock resistance and weatherability, avoids chalking or cracks during the use, needs no special maintenance after the construction, and effectively guarantees the durability and reliability.
Description
technical field [0001] The invention relates to the technical field of mechanical materials, in particular to a fireproof steel plate. Background technique [0002] Steel structure is one of the basic structural types of construction engineering. At present, steel structures are mainly used for long-span roof structures, load-bearing skeletons and supports of industrial plants, crane beams, high-rise building structures, high-rise building (structure) structures, and industrial equipment device frames. Steel structure has the advantages of high strength, light weight, small structure size, good ductility, excellent seismic performance, convenient construction and high degree of industrialization, so it is widely used in construction projects. [0003] However, due to the poor fire resistance of steel, the application of steel structures in construction projects has attracted great attention. Lessons learned from steel frame building structures and long-span roof steel stru...
