METHOD FOR DETERMINING THE BUILDING FIRE hardwood floors

摘要

FIELD: fire-prevention facilities.;SUBSTANCE: in implementation of the method a check of individual values of quality of wood construction elements is carried out, then the dangerous sections are revealed, breed and type of wood, the value of its auto-ignition temperature, the type of rolling wood covering and ignitability values of its elements are revealed, the thickness and values of thermal diffusion of fire-retardant layer material for wood of the covering boarding is identified, and using the obtained values of quality of the elements, according to analytical expression, the fire resistance limit of wood covering of the building is revealed.;EFFECT: elimination of fire tests of wooden structures in the building, reduction of labour intensity in determining the fire resistance of wood covering with the structural fire protection, expanding the technological capabilities of determining the actual fire resistance of differently engineered wood coverings, the ability of the testing the wooden structures for fire resistance without violation of functional process in the building, improving the accuracy and expressiveness of testing.;9 cl, 7 dwg
