Abstract
A literature review and analysis of fire protection means of wooden structures has been carried out. It has been established that there is a certain amount of rapid methods for determining fire-protection efficiency, which need to be finalized and universalized, so it is necessary to develop a new method and device. A device and an express method for determining fire-protection of wooden structures have been developed. This method consists in the action of the burner flame over a period on the sample from the surface of the fireproof wood and further measurement of the temperature on the reverse surface by the thermocouple and its evaluation. The study of the quality of wood fire retardant treatment according to the developed express method showed: the temperature on the underside for a sample of untreated wood averaged 200 °C, which does not meet the requirements of the standard; fire-protection coating applied one-time − 143 ºC, which corresponds to the ІІd group of this standard, and when applied twice − 97 °C and impregnated with fire retardants − 130 °C, which corresponds to the Іst group of this standard. These results allow us to conclude that it is expedient to use the proposed express method for practical implementation.
