COMPLEX TYPE FIREPROOF SYSTEM AND METHOD OF HIGH STRENGTH CONCRETE MEMBERS

摘要

PURPOSE: Composite fireproof structure and construction method for preventing explosion of a high-strength concrete member are provided to maximize the performance of each fireproof material using a metallic sheet if a fireproof-board installation method and a fireproof-paint coating method are simultaneously applied. CONSTITUTION: A composite fireproof structure for preventing explosion of a high-strength concrete member comprises a high-strength concrete member(10), a fireproof board(20), a metallic sheet(30) and fireproof paint(40). The fireproof board is attached to the outer surface of the high-strength concrete member. The metallic sheet is attached to the outer surface of the fireproof board. The fireproof agent is coated on the outer surface of the metallic sheet.
