Abstract

Abstract

ANSYS software was used to simulate the fire resistance of ALC board, carbon steel plate, rock wool board, aluminum silicate plate and multilayer composite panels (steel plate-aluminum silicate plate-air layer-aluminum silicate plate-steel plate) under the condition of HC standard temperature rise for 3 hours, so as to obtain the temperature rise curve and fire resistance limit of the backfire surface of each board.The results showed that the time to reach the fire resistance limit of carbon steel plate was 2 743 s, and the heat resistance of carbon steel plate was the worst.ALC board and aluminum silicate plate had the best fire resistance, both of which reached the fire resistance limit after 8 000 s. However, the heating trend of aluminum silicate plate was slower than that of ALC board. If the heating time became longer, the fire resistance of aluminum silicate plate would exceed that of ALC board.For composite sandwich panels, when the thickness of aluminum silicate plate was equal, the temperature of the backfire surface decreased with the increase of the thickness of air layer. Only when the thickness of air layer was 20 mm, the fire resistance limit of sandwich board reached 180℃ at 9 543 s. When the thickness of aluminum silicate board was 30 mm, the temperature of the backfire surface reached the fire resistance limit value of 180℃ at 9 372 s, and the other boards with different thicknesses did not reach the fire resistance limit. In order to verity the fire resistance of the proposed sandwich panel, a three-hour fire test was carried out, the results showed that the sandwich panel could meet the requirements of fire-resistant limit.
