FIRE-RESISTANT CASING FOR METAL THREADED STUD Russian patent published in 2021 - IPC G12B17/06 

FIELD: fire protection systems.

SUBSTANCE: proposed technical solution relates to fire protection systems and is intended for fire protection of cable facilities, including at nuclear power plants and thermal power plants, increasing the fire resistance limit of load-bearing metal structures, increasing the fire resistance limit of ventilation ducts, including at nuclear power plants and thermal power plants, finishing fire-resistant structures of industrial and construction facilities, including at nuclear power plants and thermal power plants. The invention concerns a mineral-cotton fire-resistant casing for a metal threaded stud, containing two parts connected to each other by means of a fire-resistant sealant, each of which has a coaxial cutout for the said stud for its placement in the casing when the parts of the casing are closed, and also concerns the supporting structure of the cable box, which is a suspension in the form of a metal threaded stud, equipped with the described mineral-cotton fire-resistant casing.

EFFECT: simplification of the installation process of the elements of the fire protection system of cable or cable lines, as a result, an increase in the speed of installation of the elements of the fire protection system of cable lines, as a result, a reduction in the duration of installation of the elements of the fire protection system of cable lines; as well as an increase in the fire protection of the cable economy as a whole.
