FIRE-RESISTANT MULTILAYER ARTICLE FOR FIRE PROTECTION OF BUILDING STRUCTURES Russian patent published in 2020 - IPC E04B1/94 A62C2/06 F16L57/04 

FIELD: construction.

SUBSTANCE: invention relates to non-combustible structural passive fire protection devices and can be used to protect a wide range of building structures (columns and beams, links and trusses) buildings and structures, air ducts, mounting hardware (turnbuckles), cable products, as well as structures during construction of subways and tunnels. Fire-resistant multilayer article for fire protection of building structures is an insulation cover made of incombustible multilayer material, layers of which are cross-linked to non-combustible and heat-resistant ceramic, glass-fiber or silica threads. Flame retardant bands made of twisted basalt and silica filaments and having a self-tightening attachment for clasping the jacket stretched on the building structure are sewn to the jacket.

EFFECT: invention increases fire resistance of building structures by using a fire-resistant article from a multilayer material with a fire-resistant fastening element of multiple use.
