[Abstract]:With the continuous development of high-rise buildings, people pay more and more attention to the fire problem of high-rise buildings. Elevators cannot be used as a means of escape in case of fire. Mainly limited by the elevator door fire resistance. In this paper, the fire resistance of the elevator door is studied. Through the development of the fire resistance test device, the test method, simulation analysis and fire resistance test are made to explore the fire resistance of the elevator layer door. The main research contents and results are as follows: (1) the overall layout of fire resistance test device for elevator door is constructed, including heating furnace, gas system, data acquisition system and control and analysis system. For the data acquisition system, the corresponding measuring instruments are adopted and the corresponding temperature measuring system, pressure measuring system and gas leakage measuring system are developed. The test method for the fire resistance test of the elevator door is determined, including the corresponding test principle. Test conditions, test procedures, evaluation criteria and data analysis, in which test conditions include heating conditions, pressure conditions and layer door samples, and data analysis includes the calculation of gas leakage, Using ANSYS to analyze the thermal-stress coupling of the elevator door, the temperature and stress distribution of the elevator door in the course of fire are studied, and the structure of the elevator floor door is optimized. By reasonably arranging the interval of reinforcement bars on the back fire surface of the layer door, the quantity can effectively reduce the range of the highest temperature area on the fire surface of the layer door. The fire resistance test of the elevator door is carried out. The test results are analyzed and compared with the simulation results. It is found that the experimental results are in good agreement with the simulation results. Finally, the fire resistance of the elevator door is evaluated.
