Abstract

This article presents a team of authors that discusses two different methods of fire protection of wooden beams, with one method characterized by deep impregnation of fire retardant solutions and the other characterized by lining with fireproof plywood made of impregnated veneer. Both methods are used for identical samples that are made of solid wood and are subjected to fire tests using a standard temperature curve to determine the depth of charcoal and charcoal formation. The experimental results of the fire resistance tests are given in this article and partly allow us to draw conclusions about the limit of fire resistance of wood beams and to determine the most effective method of fire protection for wood beams. In addition, we have to determine the strength properties of wooden beams.
