FIRE-RESISTANT COATING MATERIAL OF THE PASSAGEWAY Russian patent published in 2022 - IPC E04B1/94 F16L5/04 

FIELD: firefighting.

SUBSTANCE: present invention relates to a fire-resistant coating material of the passageway and, in particular, to a fire-resistant coating material applied in creating the passageway coated for fire protection in a wooden building. The material (10) of the fire-resistant coating of the passageway applied in creating the passageway (11) coated for fire resistance in a fire-resistant beam (20), which is a fire-resistant building element in the structure of a wooden building, wherein the material (10) of the fire-resistant coating of the passage part is imparted a tubular shape by stacking multiple plasterboard parts (13a) created from plasterboard sheets in the direction of thickness and connecting the multiple plasterboard parts (13a) as a whole. The material (10) of the fire-resistant coating of the passageway is imparted a tubular shape by stacking multiple plasterboard parts (13a), preferably in an annular shape, cut from series-produced and commercially available plasterboard sheets with a thickness of 9.5 to 25.5 mm, while fastening the multiple plasterboard parts (13a) with each other, preferably applying metal fasteners such as staples (14), and connecting the multiple plasterboard parts (13a) as a whole.

EFFECT: creation of a fire-resistant material for coating a passageway in a wooden building.
