FIELD: construction.
SUBSTANCE: steel pillar double tee is equipped with fastening nuts and setting screws with hidden heads and screwed-in sharpened end. The elements of the sheet lining are fixed tightly to the shelves of the pillar double tee, elements of the tile lining - tightly to the double tee wall. Thickness of elements of fireproof lining is pre-determined with account of thermal properties of its materials, conditions of pillar double tee heating during fire and normative limit of building pillar fire resistance.
EFFECT: increased reliability of fixation of elements of large-size lining, increased limit of steel pillar fire resistance, reduced risk of pillar collapse in initial stage of fire.
