Abstract: In order to realize the over temperature alarm when the structural members in the building reach the failure temperature, based on the characteristics of high temperature melting of solid metal, over temperature alarm device and high temperature protection method of structural members are developed with the experimental research and finite element analysis. The research results show that the developed over temperature alarm device can realize the over temperature alarm when the structural member reaches the failure temperature. The high temperature protection of the over temperature alarm device can be effectively realized by using the thermal insulation protection method of the combination of fireproof board and aerogel blanket.
